PENGARUH KONFIGURASI KELOMPOK TIANG TERHADAP PENURUNAN DAN GAYA DALAM PADA TIANG
type: item
description: Fondasi memiliki peranan penting dalam perencanaan konstruksi karena berfungsi menyalurkan beban dari struktur bangunan ke lapisan tanah yang lebih stabil di bawah permukaan. Dalam proses perancangannya, fondasi dibagai menjadi 2 bagian yaitu: fondasi dangkal dan fondasi dalam (tiang pancang/bor). Tiang pancang diklasifikasikan sebagai fondasi dalam dan digunakan saat lapisan tanah bagian atas tidak cukup kuat untuk menopang beban struktur atau bangunan, sehingga beban perlu dialihkan ke tanah yang lebih dalam dan stabil. Dalam dunia konstruksi juga dikenal sistem tiang kelompok, yaitu susunan beberapa tiang yang digabung dan disatukan menggunakan pile cap. Dalam penggunaan tiang kelompok, jumlah tiang dan bentuk pile cap dapat disesuaikan, yang biasa disebut dengan konfigurasi tiang. Penelitian ini akan difokuskan pada analis kelompok tiang pancang yang mencakup perhitungan daya dukung ujung, daya dukung selimut, serta deformasi tiang berdasarkan data tanah dan konfigurasi tiang yang telah ditetapkan. Tujuan penelitian adalah untuk menganalisis dan membandingkan penurunan konfigurasi tiang yang optimal sesuai dengan karakteristik tanah yang digunakan.

ANALYSIS OF THE EFFECT OF CH₃COOH ADDITION ON SOIL IMPROVEDWITH 10 % LIME CONTENT
type: item
description: Acid rain is a serious threat to the durability of geotechnical infrastructure, particularly in highly polluted industrial areas such as Jakarta. This phenomenon may damage the stability of chemically improved road subgrade through the dissolution of binding materials. This study aims to evaluate the strength degradation of subgrade soil stabilized with 10% lime under acid exposure. A laboratory experimental method was conducted by comparing native Puri Indah soil with lime-stabilized soil under three immersion conditions: no immersion (control) to determine initial strength, normal water immersion (pH 7.02) to simulate typical flooding, and acetic acid immersion (pH 5.21) to simulate extreme acid rain. The results indicate that 10% lime stabilization in the control condition produced a high CBR value of 46%. Normal water immersion caused a slight decrease to 44%, while acid exposure resulted in severe degradation with CBR dropping sharply to 27%. The significant gap between water and acid immersion confirms chemical deterioration due to neutralization reactions dissolving lime binders. It is concluded that although 10% lime effectively increases initial strength, this content lacks sufficient alkalinity to withstand long-term acid attack. Abstrak Hujan asam merupakan ancaman serius bagi durabilitas infrastruktur geoteknik, khususnya di kawasan industri padat polusi seperti Jakarta. Fenomena ini berpotensi merusak stabilitas tanah dasar jalan yang telah diperbaiki secara kimiawi melalui mekanisme pelarutan bahan pengikat. Penelitian ini bertujuan untuk mengevaluasi degradasi kekuatan tanah dasar yang distabilisasi dengan kapur kadar 10% akibat paparan asam. Metode eksperimental laboratorium dilakukan dengan membandingkan karakteristik tanah asli Puri Indah dengan tanah campuran kapur pada tiga kondisi perendaman: tanpa rendaman (kontrol) untuk mengetahui kekuatan awal, rendaman air biasa (pH 7,02) sebagai simulasi genangan normal, dan rendaman larutan asam asetat (p…

ANALISIS PERKUATAN FERROCEMENT TERHADAP SAMBUNGAN BALOK KOLOM MENGGUNAKAN MIDAS FEA
type: item
description: This study evaluates the structural behavior of reinforced concrete beam–column joints strengthened with ferrocement using nonlinear finite element analysis performed in MIDAS FEA. Beam–column joints are critical regions in reinforced concrete structures, particularly under seismic loading, where strength and ductility demands are significant. Five numerical models were analyzed, consisting of one unstrengthened control model and four strengthened models with variations in wire mesh diameter, number of wire mesh layers, and mortar compressive strength. The analysis focused on the load–displacement response, ultimate load capacity, ductility, and failure mechanisms of the joints. The results show that ferrocement strengthening significantly improves joint performance by increasing the initial cracking load and ultimate load by approximately 35–40% compared to the unstrengthened model. Among the strengthened configurations, the model with higher mortar compressive strength (fc45) exhibited the highest ultimate capacity and ductility, accompanied by a more stable post-cracking response and delayed crushing of the core concrete. Overall, the findings confirm that ferrocement is an effective strengthening technique for enhancing the strength, ductility, and crack control of reinforced concrete beam–column joints, with mortar compressive strength having a more dominant influence than the number of wire mesh layers. Abstrak Penelitian ini mengevaluasi perilaku struktural sambungan balok–kolom beton bertulang yang diperkuat menggunakan ferrocement melalui analisis elemen hingga nonlinier dengan perangkat lunak MIDAS FEA. Sambungan balok–kolom merupakan elemen kritis dalam struktur beton bertulang, khususnya terhadap beban gempa, sehingga peningkatan kapasitas dan daktilitasnya menjadi aspek yang penting. Dalam penelitian ini dianalisis lima model numerik, yang terdiri dari satu model tanpa perkuatan sebagai pembanding dan empat model dengan perkuatan ferrocement yang divari…

ANALISIS KESIAPAN EKOSISTEM KENDARAAN LISTRIK JAKARTA DENGAN PENDEKATAN IPA
type: item
description: This research evaluates Jakarta's readiness for Battery Electric Vehicle (BEV) adoption as a strategy to reduce emissions. Utilizing a survey of 100 car users in DKI Jakarta, the study employs Descriptive Statistics and Importance Performance Analysis (IPA) to map gaps between respondent expectations and perceptions regarding infrastructure and regulations.Findings reveal primary challenges such as limited SPKLU (charging station) availability and regulatory inconsistencies. Based on the IPA matrix, ease of access to SPKLU locations is identified as the most pressing priority (Quadrant A), rated high in importance but low in performance. Conversely, the ecosystem’s strengths (Quadrants B and D) include effective non-fiscal policies like odd-even rule exemptions, successful mitigation of range anxiety, and attractive incentives.The strategic recommendation for the DKI Jakarta Provincial Government is to prioritize the development of real-time applications to improve SPKLU information accessibility. Furthermore, maintaining successful policies is essential for promotional efforts to build public trust in the BEV ecosystem. Abstrak Penelitian ini mengevaluasi kesiapan DKI Jakarta dalam adopsi Kendaraan Bermotor Listrik Berbasis Baterai (KBLBB/BEV) untuk mereduksi emisi gas karbon. Melalui kuesioner terhadap minimal 100 pengguna mobil, data dianalisis menggunakan Statistik Deskriptif dan Importance Performance Analysis (IPA) guna memetakan kesenjangan antara ekspektasi dan persepsi responden terhadap infrastruktur serta regulasi. Hasil penelitian mengidentifikasi tantangan utama berupa keterbatasan jumlah dan distribusi SPKLU yang tidak merata, serta ketidakkonsistenan regulasi. Analisis IPA menunjukkan bahwa kemudahan akses informasi lokasi SPKLU berada di Kuadran A (Prioritas Utama), yang berarti sangat penting namun kinerjanya masih rendah. Sebaliknya, kekuatan ekosistem (Kuadran B dan D) terletak pada efektivitas kebijakan non-fiskal seperti pembebasan ganjil-genap,…

ANALISIS PERKUATAN RANGKA STRUKTUR BETON BERTULANG MENGGUNAKAN DINDING STRUKTUR DENGAN MIDAS FEA NX
type: item
description: The addition of reinforced concrete walls is an effective reinforcement solution for reinforced concrete structures. However, openings for architectural and mechanical purposes are unavoidable. This study aims to validate the accuracy of the Finite Element Method (FEM) using MIDAS FEA NX in predicting the structural behavior of walls with openings, as well as analyzing the effect of variations in the ratio of wider openings. Numerical modeling uses material properties and dimensions identical to experimental research on a 1/3 scale. Four models were validated (REF, FRCSS, HRCSS-1, HRCSS-2) with simulation results differing from the laboratory by 0.92%-3.47%. The model uses smeared crack concrete for concrete and von Mises for steel reinforcement. The results show that adding structural wall reinforcement increases the lateral load capacity up to 14 times (from 23.57 kN to 333.12 kN). However, increasing the opening ratio from 0% to 10.3%, 15%, and 20% reduced the structural capacity by 29.29%, 31.14%, and 38.04%, respectively. This study provides guidance on the optimal opening range for practical design in high seismic zones, especially in Indonesia. Abstrak Penambahan dinding struktur beton bertulang merupakan solusi perkuatan efektif pada struktur beton bertulang. Namun, keberadaan bukaan untuk keperluan arsitektural dan mekanikal tidak dapat dihindarkan. Penelitian ini bertujuan memvalidasi akurasi Metode Elemen Hingga (FEM) menggunakan MIDAS FEA NX dalam memprediksi perilaku struktural dinding dengan bukaan, serta menganalisis pengaruh variasi rasio bukaan yang lebih luas. Pemodelan numerik menggunakan properti material dan dimensi identik dengan penelitian eksperimental pada skala 1/3. Empat model divalidasi (REF, FRCSS, HRCSS-1, HRCSS-2) dengan perbedaan hasil simulasi terhadap laboratorium berkisar 0,92%-3,47%. Model menggunakan smeared crack concrete untuk beton dan von Mises untuk baja tulangan. Hasil menunjukkan penambahan perkuatan dinding struktur menin…

type: item
description: This study aims to analyze the potential implementation of a Rainwater Harvesting (RWH) system in Long Melaham Village, Mahakam Ulu Regency, East Kalimantan. The system is proposed as an alternative source of clean water for communities that are not yet served by the public water supply network (PDAM). The data used include daily rainfall records from 2015–2024 obtained from the Aji Pangeran Tumenggung Pranoto Meteorological Station (BMKG Samarinda) and roof area measurements from nine public buildings. The rainwater volume was calculated using the equation V = R × A × C / 1000, with runoff coefficients (C) of 0.8 for tile roofs and 0.9 for metal roofs, following the SNI 6728.1:2015 standard. The results show an effective rainfall of 12.24 mm/day and domestic water demand of 60–80 liters per capita per day. School, mosque, and church buildings can meet daily water needs, while village halls and health posts require additional storage capacity. Overall, the RWH system is considered effective, economical, and sustainable for rural areas. Abstrak Penelitian ini bertujuan untuk menganalisis potensi penerapan sistem Pemanenan Air Hujan (PAH) di wilayah Desa Long Melaham, Kabupaten Mahakam Ulu, Kalimantan Timur. Sistem ini diusulkan sebagai alternatif penyediaan air bersih bagi masyarakat yang hingga kini belum terlayani jaringan PDAM. Data yang digunakan meliputi curah hujan harian periode 2015–2024 dari Stasiun Meteorologi Aji Pangeran Tumenggung Pranoto (BMKG Samarinda) serta luas atap sembilan bangunan publik.

ANALISIS STABILITAS LERENG MENGGUNAKAN BAMBOO CRIB WALL
type: item
description: Slope stability is a critical aspect of geotechnical engineering, particularly on steep terrains prone to landslides. This study analyzes the effectiveness of Bamboo Crib Walls as an eco-friendly and economical reinforcement alternative by comparing single-trap and multi-trap (terraced) designs. Stability analysis was conducted using the Limit Equilibrium Method on a 14-meter high slope with a 60° inclination in Tambakmerang Village, Wonogiri. Simulation results showed the existing slope has a Safety Factor (SF) of 1.366. While categorized as relatively stable, it fails to meet the SNI 8460:2017 standard for permanent slopes with high uncertainty, which requires an SF ≥ 2.0. The single-trap design (H = 4 m, B = 3 m) increased the SF to 1.571, yet remained below the minimum national requirement. In contrast, the terraced design (2-trap) with identical dimensions achieved optimal stability with an SF of 2.823, significantly exceeding the safety standard. This study concludes that the terraced Bamboo Crib Wall is the most effective solution, as the terracing system provides superior load distribution and retention compared to the single-trap model in resisting driving forces on steep slopes. Abstrak Stabilitas lereng merupakan aspek krusial dalam rekayasa geoteknik, terutama pada topografi curam yang rentan terhadap kelongsoran. Penelitian ini bertujuan menganalisis efektivitas Bamboo Crib Wall sebagai alternatif perkuatan ramah lingkungan dan ekonomis dengan membandingkan desain tunggal (single-trap) dan bertingkat (multi-trap). Analisis stabilitas dilakukan menggunakan Metode Kesetimbangan Batas pada lereng setinggi 14 meter dengan sudut kemiringan 60° di Desa Tambakmerang, Wonogiri. Hasil simulasi menunjukkan bahwa lereng eksisting memiliki Faktor Keamanan (FK) sebesar 1,366. Kondisi ini dikategorikan relatif stabil namun belum memenuhi standar SNI 8460:2017 untuk lereng permanen dengan tingkat ketidakpastian tinggi yang mensyaratkan FK ≥ 2,0. Penerapan Bamboo Crib …

EVALUASI PERMEABILITAS CAMPURAN TANAH BSD DENGAN VARIASI BENTUK BUTIRAN PASIR MENGGUNAKAN METODE FALLING HEAD
type: item
description: This study aims to evaluate the permeability levels of soil and various types of sand, as well as to examine the influence of their physical properties on permeability values. The soil sample was sourced from Bumi Serpong Damai (BSD), while the sand samples consisted of six variants: Red Malang Sand, Black Malang Sand, river sand, Cibeet Sand, Lombok Sand, and Garut Sand. The research involved a series of laboratory tests, including index properties, Atterberg limits, soil compaction, and permeability testing using the falling-head method. The falling head tests employed standpipes with three different diameters of 4 mm, 6 mm, and 10 mm. The findings reveal that the physical characteristics of the sand—such as grain size distribution, gradation, density, and moisture content *significantly affect the permeability values. Moreover, the combination of soil and sand with mixture variations of 20%, 30%, and 40% also influences permeability levels, with higher sand content generally resulting in greater permeability. These results provide insight into the permeability variations among different soil and sand types, which could serve as a valuable reference in construction planning and implementation. This study is also expected to contribute to more effective permeability control strategies. Abstrak Penelitian ini bertujuan untuk mengevaluasi tingkat permeabilitas pada tanah dan berbagai jenis pasir serta menelaah pengaruh sifat-sifat fisik terhadap nilai permeabilitas tersebut. Tanah diambil dari Bumi Serpong Damai (BSD), sementara pasir yang digunakan terdiri dari enam varian, yaitu Pasir Malang Merah, Pasir Malang Hitam, pasir sungai, Pasir Cibeet, Pasir Lombok, dan Pasir Garut. Proses penelitian dilakukan melalui sejumlah uji laboratorium, meliputi pengujian index properties, Atterberg limit, pemadatan tanah (compaction), serta uji permeabilitas dengan metode falling head. Pengujian falling head ini menggunakan selang ukur dengan tiga variasi diameter yaitu 4 mm, 6 m…

PERBAIKAN ANGKA CALIFORNIA BEARING RATIO PADA TANAH LANAU DENGAN CAMPURAN LIMBAH ALUMINIUM & KACA
type: item
description: This study aims to evaluate the improvement of the California Bearing Ratio (CBR) value of silt soil using aluminum and glass waste mixtures. In highway engineering, a higher CBR value indicates better soil bearing capacity. The soil sample was taken from the Pantai Indah Kapuk 2 area in Tangerang, Banten, and tested at the Soil Mechanics Laboratory of Tarumanagara University. Waste mixtures were tested at 4%, 8%, and 12% concentrations for both aluminum and glass. The results show that glass waste mixtures yield more significant increases in California Bearing Ratio values compared to aluminum waste. The highest California Bearing Ratio value with glass was achieved at 12% concentration, with a 6.61% increase, whereas the aluminum mixture reached its peak at 8% with a 4.42% increase. A decrease at 12% aluminum suggests that excessive material does not necessarily improve bearing capacity. These findings suggest that glass waste is more effective in enhancing the mechanical properties of subgrade soils compared to aluminum waste. Furthermore, this supports sustainable development principles by utilizing industrial waste in civil engineering applications. Abstrak Penelitian ini bertujuan untuk mengevaluasi peningkatan nilai California Bearing Ratio (CBR) pada tanah lanau menggunakan campuran limbah aluminium dan kaca. Dalam konteks rekayasa jalan raya, nilai California Bearing Ratio yang tinggi mencerminkan daya dukung tanah yang baik. Tanah yang digunakan berasal dari wilayah Pantai Indah Kapuk 2, Tangerang, Banten, dan diuji di Laboratorium Mekanika Tanah Universitas Tarumanagara. Variasi campuran limbah yang diuji adalah 4%, 8%, dan 12% untuk masing-masing jenis limbah. Hasil penelitian menunjukkan bahwa campuran limbah kaca memberikan peningkatan nilai California Bearing Ratio yang lebih signifikan dibandingkan limbah aluminium. Nilai California Bearing Ratio tertinggi pada campuran kaca tercapai pada 12% dengan peningkatan sebesar 6,61%, sedangkan pada limbah al…

EVALUASI TARIF DAN KELAYAKAN OPERASIONAL ANGKUTAN UMUM DI TRAYEK KUPANG-NOELBAKI BERDASARKAN BOK, ATP, DAN WTP
type: item
description: Public transportation plays an essential role in supporting community mobility in developing cities such as Kupang, where informal modes like bemo remain widely used. Increasing fuel prices and vehicle maintenance costs require periodic fare evaluations to ensure operational sustainability. This study evaluates the feasibility of public transport fares on the Kupang–Noelbaki route based on Vehicle Operational Costs (BOK), drivers’ income, and passengers’ Ability to Pay (ATP) and Willingness to Pay (WTP). A descriptive quantitative approach was applied through field observations, surveys of 100 passengers, and in-depth interviews with five drivers. The results show that the annual BOK of Rp194,200,000 corresponds to a daily operational cost of Rp647,000, while average daily revenue reaches Rp912,500, resulting in a net driver income of Rp265,500 per day. The ATP and WTP values are Rp7,000 and Rp6,500, respectively, indicating that the current fare of Rp5,000 remains affordable for passengers. Fare simulation analysis suggests that a moderate fare increase to Rp6,000 is still acceptable and can improve driver income. These findings emphasize the importance of data-driven fare evaluation and service quality improvement in public transport policy. Abstrak Transportasi publik memiliki peran penting dalam mendukung mobilitas masyarakat di kota berkembang seperti Kupang, yang masih mengandalkan moda transportasi informal berupa bemo. Kenaikan harga bahan bakar dan biaya perawatan kendaraan menuntut evaluasi tarif secara berkala untuk menjamin keberlanjutan operasional. Penelitian ini bertujuan mengevaluasi kelayakan tarif angkutan umum pada trayek Kupang–Noelbaki berdasarkan Biaya Operasional Kendaraan (BOK), pendapatan pengemudi, serta Ability to Pay (ATP) dan Willingness to Pay (WTP) penumpang. Metode penelitian menggunakan pendekatan deskriptif kuantitatif melalui observasi lapangan, survei terhadap 100 penumpang, dan wawancara mendalam dengan lima pengemudi. Hasil anal…

EFEK VARIASI PERILAKU SENDI PLASTIS PADA ANALISIS PUSHOVER SISTEM RBKK TIPE INVERTED-V
type: item
description: The study was conducted on a six story plus an additional roof level of Special Concentrically Braced Frame (SCBF) steel structure. The lateral force resisting system consists of inverted-V bracing arranged as single-bay frames along each building perimeter. Variable of this study is the location of plastic hinges. In model 1, deformation controlled plastic hinges are assigned to the bracing, while force controlled plastic hinges are assigned to the columns and beams. In model 2, deformation controlled plastic hinges are assigned to columns, beams, and bracing. Structural evaluation was performed using pushover analysis by ETABS. The results show that hinge location variations have minimal influence on the performance point and ductility parameters (R, Ω0, dan Cd). The average differences in base shear dan displacement at the performance point between model 1 dan model 2 are 0.51% and 0.56% respectively. The differences in ductility parameters for model 1 and model 2 are 1%, 0%, 1.4% in the x direction and 1%, 0%, 1% in the y direction for R, Ω0, dan Cd respectively. However, it significantly affects the plastic hinge mechanism and performance level. The first component to exceed >CP level in model 2 is the bracing, whereas in model 1 it is the beams. The performance targets for model 2 at the MCE hazard level is LS for both directions but the performance targets for model 1 at the MCE hazard level are LS in the x direction and CP in the y direction. Overall, model 1 exhibits poorer structural performance level. Abstrak Penelitian dilakukan pada struktur rangka baja terbreis konsentris khusus (RBKK), 6 lantai ditambah atap.

KINERJA SEISMIK SISTEM RANGKA PEMIKUL MOMEN BEBAN GRAVITASI DENGAN SCWB DAN WCSB PADA GEDUNG BAJA 5 LANTAI
type: item
description: This study reviews the performance of the special moment resisting frame (SMRF) structure of steel structure buildings using highly ductile member (HDM) steel profiles in high seismic areas against gravity loads as a 'baseline' before further seismic analysis is carried out aimed at evaluating the performance level, how many performance points, collapse patterns, and capacity curves. This study conducted structural modeling into 4 models, model 1 was designed using joint placement and strong column weak beam (SCWB) steel profiles. Model 2 was designed using clamped placement and SCWB steel profiles. Model 3 was designed using joint placement and weak column strong beam (WCSB) steel profiles. Model 4 was designed using clamped placement and WCSB steel profiles. Then from the four models, a pushover analysis was carried out to compare the performance of the building structure which model is better.

EVALUASI KEKUATAN TANAH DASAR BERDASARKAN UJI CALIFORNIA BEARING RATIO PADA SUATU RENCANA KAWASAN WISATA
type: item
description: Subgrade strength is a crucial factor in pavement design for areas subjected to static and dynamic traffic loads. This research aims to evaluate the subgrade's bearing capacity at a planned tourism area in Lembang, West Java. The evaluation was conducted using the field CBR test method in accordance with ASTM D 4429 and SNI 1738:2011. Data collection was carried out at 12 scattered areas, covering a total of 89 representative test points. The results show that the actual CBR values varied significantly with average values at each test area ranging from 4.35% to 6.45%. Although all values met the minimum design requirement (>2%), most of the subgrade conditions were classified as "Very Poor" to "Poor-Fair" and remained below the 6% threshold. This condition indicates low subgrade bearing capacity, high deformation potential, and non-uniform subgrade properties, so it is recommended to carry out soil improvement before the pavement construction stage is carried out in the planned tourism area. Abstrak Kekuatan tanah dasar (subgrade) merupakan faktor krusial dalam perencanaan perkerasan yang akan menanggung beban lalu lintas statis dan dinamis.

ANALISIS PENYEBAB BANJIR PADA SALURAN BETON PRACETAK PADA DUA DAERAH RAWAN BANJIR DI SURABAYA
type: item
description: Flooding is a major issue in drainage channels, including those that have already implemented box culverts, eventhough box culverts are considered one of the alternatives for flood control. This issue arises due to various factors such as channel capacity, channel slope, catchment area, and sedimentation. This research focuses on two channels, which are located on Jalan Tanjung Sari and Jalan Ketintang. The purpose of this research is to determine their effectiveness and identify the main factors causes of flooding. This research using primary and secondary data analysis, calculations, and HEC-RAS simulations. The results indicate that the channel on Jalan Tanjung Sari contains a significant amount of sediment, which causes the channel to overflow. Meanwhile, the channel on Jalan Ketintang has relatively low effectiveness, which is attributed to the difference between the actual field slope and the planned design slope. Sedimentation also contributes to the reduction of channel capacity. However, the main factor causing flooding in the channel at Jalan Ketintang is the discrepancy between the actual field slope and the planned slope, which may result from construction errors or accumulated sediment that makes the slope shallower. Abstrak Banjir merupakan masalah utama pada suatu saluran, termasuk saluran yang sudah mengaplikasikan box culvert. Padahal saluran box culvert dijadikan salah satu alternatif penanggulangan banjir.

EKSPLORASI POTENSI COCOPEAT DALAM PENGEMBANGAN GEOMEMBRAN RAMAH LINGKUNGAN UNTUK PENAHAN AIR BAWAH TANAH
type: item
description: This study aims to explore the potential of cocopeat as an environmentally friendly alternative material for groundwater retention applications. Conventional geomembranes made of High-Density Polyethylene (HDPE) have been proven to be highly effective in controlling water infiltration; however, they present sustainability challenges due to their non-biodegradable nature. Therefore, cocopeat, a coconut husk by-product abundantly available in West Kalimantan, is investigated as an organic-based alternative material—not as a replacement for synthetic geomembranes, but as a complementary solution for groundwater conservation under specific conditions and scales of application. This research employed a laboratory experimental method involving the washing and drying of cocopeat, mixing with biodegradable resin and water, sample molding, and permeability testing using the falling head method. The results indicate that cocopeat-based geomembranes exhibit an average permeability coefficient of 3.5902 × 10⁻⁶ cm/s, which falls into the slightly impermeable (semi-impermeable) category. These findings demonstrate that cocopeat is capable of functioning as a water infiltration barrier, although its impermeability remains lower than that of synthetic geomembranes such as HDPE. With its fine porous structure, high water absorption capacity, and stable pH ranging from 5.07 to 6.5, cocopeat shows potential for use as a groundwater retention material in conservation-oriented applications, including infiltration ponds, small reservoirs, and eco-friendly drainage base layers. Furthermore, the utilization of cocopeat contributes to organic waste reduction and supports the development of sustainable, locally sourced materials in civil engineering. This study provides a fundamental basis for further research focusing on composition optimization, compaction techniques, and field-scale testing to expand the application of cocopeat as an alternative material for groundwater retention.

LOLEO AIRPORT REVIEW: CATALYST FOR SUSTAINABLE SHIFTING OF NORTH MALUKU’S CAPITAL TO SOFIFI
type: item
description: Fifteen years after it attained the administrative status of North Maluku's capital, Sofifi continues to suffer from political strife, infrastructural deficits and uneven spatial development, but Ternate is poised in terms of economic and social dominance. Filling the essential knowledge gap on whether airport-led infrastructure—airborne connectivity through the new Loleo Airport—can ignite Sofifi to function as an effective provincial capital, we investigate through the qualitative-descriptive approach regional planning reports (RTRW, RPJPD, RZWP3K), research and policy publications, spatial databases (land cover change, NDBI analysis), and on-site site visit in Sofifi and Ternate. Our research demonstrates airport-led development in connectivity can redirect cityward development inlandward, stimulate diversified economic activities—agritourism and logistics especially—and link marginalized sub-districts into larger transport systems. Furthermore, through integrating local wisdom in airport precinct planning and aligning legislative improvements with development planning, Loleo Airport is perceived as an integrating node reducing elite conflictiveness, leveling out deficiencies in service provision, and integrating cultural heritage. These findings underscore the necessity of marrying planned infrastructure expenditure with inclusive governance and spatial planning to attain balanced development and legitimate Sofifi as North Maluku's economic and administration capital. Abstrak Lima belas tahun setelah memperoleh status administratif sebagai ibu kota Maluku Utara, Sofifi terus menderita akibat perselisihan politik, defisit infrastruktur, dan pembangunan spasial yang tidak merata, sementara Ternate siap untuk mendominasi secara ekonomi dan sosial.

PENGARUH ABU CANGKANG KELOMANG SEBAGAI SUBSTITUSI SEMEN TERHADAP KUAT TEKAN BETON
type: item
description: Cement production grows by around 5-6.5% per year. Cement is made from a mixture of materials, one of which is limestone, with a portion of 75-90%. Most limestone is formed from shells, skeletons, and remains of dead marine organisms that go through geological processes over thousands to millions of years. Therefore, alternative materials that are more environmentally friendly and sustainable are important to reduce cement use. Hermit crab shell ash was studied in this study as a partial substitute for cement in concrete mixtures. The substitution variations used were 0%, 3%, 5%, and 7% of the cement weight. The mixture plan fc' 25 MPa based on SNI 03-2834-2000. The test specimen was a 15x30 cm cylinder and was cured by immersion for 28 days based on SNI 2493:2011. Compression testing was based on SNI 1974:2023. The results showed a decrease in compressive strength, but not significantly. A 3% substitution yielded the best results compared to the others, with a reduction in compressive strength of around 2.3%. Hermit crab shells have the potential to be a sustainable alternative material to limestone without the need for geological processes that take thousands to millions of years. Abstrak Produksi semen tumbuh sekitar 5-6,5% per tahun. Semen terbuat dari campuran bahan, salah satunya adalah batu kapur dengan porsi 75-90%. Sebagian besar batu kapur terbentuk dari cangkang, kerangka, dan sisa-sisa organisme laut mati yang melalui proses geologis dengan waktu ribuan hingga jutaan tahun. Oleh sebab itu, material alternatif yang lebih ramah lingkungan dan berkelanjutan menjadi penting untuk mengurangi penggunaan semen. Abu cangkang kelomang dikaji dalam penelitian ini sebagai substitusi sebagian semen dalam campuran beton. Variasi substitusi yang digunakan yaitu sebesar 0%, 3%, 5%, dan 7% terhadap berat semen. Rencana campuran fc’ 25 MPa berdasarkan SNI 03-2834-2000. Benda uji berupa silinder 15x30 cm dan dirawat rendam selama 28 hari berdasarkan SNI 2493:2011. Pegujia…
