PENGGUNAAN METODE SLOPE DEFLECTION PADA STRUKTUR PORTAL BERGOYANG STATIS TAK TENTU DENGAN KEKAKUAN YANG TIDAK MERATA DALAM SATU BALOK DAN KOLOM

Jemmy Wijaya, Faniwaty Itang

Various method which can be used to analyze the statically indeterminate beam with beam's difference stiffness EI is a Slope Deflection method, Consistent Deformation method, Clayperon method, Cross method and Matrix. In this paper the Slope Deflection method will be discussed in the completion of statically indeterminate swaying portal with a difference of the beam's stiffness EI in beam and column. In the application of the Slope Deflection method, there are somethings that should be known in advance which is round the corner at a point and moment magnitude of the primary (fixed end moment) at the ends of the beam due to external loads and sway movement.

PERANCANGAN DAN REALISASI SISTEM PENGERING BUAH APEL MENGGUNAKAN LAMPU INFRAMERAH

Gary Jonathan Salli, Joni Fat

Drying is a way to remove water from a material with thermal energy from natural sources (sunlight) or
unnatural sources (drier). The water contained in the material should be reduced to the level which microbes
cannot grow up. Traditional fruit drying process usually lasts for 2-3 weeks under the sunlight. This device is
designed to replace heat from sunlight so it can dry fruit on unfavorable weather conditions such as night,
cloudy, and raining. The purpose of this project is to make an apple dryer system using infrared heaters for
households. It also can read the temperature, control output voltage, and estimate the time needed to dry the
apples. Apples dryer system is testing the output of lamp timer module. After receiving input from the
temperature sensing modules, the processing module regulator ordered the lights to dim the lights to lower the
temperature to avoid overheating. The design of this dryer system able to perform drying apples. Hot on the
dryer system relies on a given output voltage. The higher the output voltage can provide the heat generated by
the infrared heater. Dryer systems can dry the apples by the time desired by the user.

Wellson Susanto, Maria Veronica Gandha

Companion animal is a part of daily life for some people in DKI Jakarta. But not all of the people care about
animal welfare. We can see it from how much case about animal abuse and illegal animal transaction. That case
already reported by institution who related with animal welfare. In my research, I review about animal welfare
standart and compare it with the real companion animal’s condition in DKI Jakarta. My research method is
literature study, questionnaire and interview with institution who related with animal welfare. The result of my
research find out that people need education about companion animal and the other facilities that support it. I
present that solution with architecture design. That design is about the architecture program, the form of space
about the program and the location of the program.

USULAN PENERAPAN MATERIAL REQUIREMENT PLANNING (MRP) UNTUK PENGENDALIAN PERSEDIAAN BAHAN BAKU PRODUK ANT INK (STUDI KASUS: CV. SINAR MUTIARA)

Paula Theresia, Lithrone Laricha Salomon

CV. Sinar Mutiara is a ink manufacturing manufacture of ink or paint stencil. Based on the results of the survey
in the field, the company has yet to have a method that is specialized in raw material inventory planning. In
doing raw material inventory planning begins with a sales forecast based on historical data with DES, DMA,
Liner Regression, and Quadratic. After that calculating forecasting error parameter with MAD, ME, MSE and
MAPE then selected forecasting is DMA (5X5) method. The problems that exist in the company, especially in
raw material inventory is excess stocks of raw materials of ink or paint stencil, especially for products PSN
Yellow, PSN Orange, PSN Blue and PSN Warm Red. As a result of excess stock this increased inventory costs.
To reduce inventory costs then do the planning starts from the raw materials forecasting with the method
according to the pattern of demand and select the best method based on the value of the smallest error. Then
perform the aggregate planning, disaggregate, lot sizing calculation and application of Material Requirement
Planning (MRP). With MRP implementation, the purchase of raw materials more precisely. Lot sizing
calculations using Silver Meal, Least Unit Cost (LUC), Wagner-Within Algorithm. Wagner-Within Algorithm
method produces a total cost of inventory is Rp 958.147.746 the lowest compared to other methods.

INVENTARISASI DAN PENILAIAN BANGUNAN CAGAR BUDAYA PADA KAMPUNG BANDAR DAN KOTA LAMA KUPANG DENGAN HISTORICAL SITE INVENTORY METHOD

Maria Bergita A. Hurek, Ifana Puteri Maryudha, Suryono Herlambang

Nowadays, cities are developing in many aspect, but unconsciously it has been removing the proof of any history
and the journey story of the city. It is going on in several cities in Indonesia, the one is in Old Town Kampung
Bandar, Pekanbaru, Riau Province and the Old City of Kupang, East Nusa Tenggara Province. Application of
the Historical Site Inventory method in the stage of assessing the building's history can be an alternative to classify
the building which included a Heritage Building. It can cover up the story and identity of each city, so it can be
planned and known by the citizen and another people as the Cultural and Historical Tourism Destination. As the
inventory has been done, Old Town Kampung Bandar has 3 buidling that assessed as Heritage building Class A
(Main). That are Masjid Raya Senapelan Pekanbaru, Rumah Singgah Tuan Qhadi and Marhum Bukit & Marhum
Pekan. In Group B (Associate) there are Terminal Old City of Pekanbaru and Lembaga Adat Melayu Riau, and
so on Group C (Primary) there is Pasar Bawah or Pasar Wisata. While in the Old City of Kupang found that
buildings including heritage buildings Class A (Main) is Kopan Old Prison, Ex Netherlands Offices, Kerkoff, and
Kota Kupang’s Church and in Group B (Associate) there are Fort Concordia and Dermaga Kopan. Overall
Historcial Site Inventory method and Assessment Heritage Buildings can be easily applied to both the object of
study, although still found any difficulties and deficiencies in the application of that methods.

PERANCANGAN DAN ANALISIS KEKUATAN KONSTRUKSI DAN POWERTRAIN PADA PROTOTYPE HAND-CRANK CYCLE (SEPEDA ENGKOL TANGAN)

Hand-Crank Cycle is a type of human-powered land vehicle which powered by the arms rather than the legs as
on a bicycle. Hand-Crank Cycle is a tricycle in form, with two coasting rear wheels and one steerable powered
front wheel. On this Hand-Crank Cycle design, performed modeling and construction load simulation was made
and simulated by the help of Autodesk Inventor Professional 2017 Software. On the load simulation dan
powertrain calculation, it was shown that Hand-Crank Cycle’s construction have a good strength and abilty to
receive the maximum load that given and the power that sourced from the human’s hands still enough to drive it
safely.

PENERAPAN ASPEK PERKEMBANGAN ANAK DALAM PERANCANGAN SEKOLAH ALAM BARUNA BAHARI

Maria Veronica Gandha, Hedista Rani Pranata

Low knowledge of Indonesian children about their natural realm, especially in the maritime field, indicates the
Indonesian educational curriculum is centered on teachers and textbooks without any direct interaction with the
object of learning. This fact is an irony for Indonesia which is seizing back its maritime glory. Uplifting this
maritime field in Indonesia could be a big challenge and difficult. It takes passion from generation to generation,
not only from the government. Elementary school became the most significant point for Indonesian youth mental
revolution. Besides children spend more time in school, apparently adult’s intelligence capabilities are rapidly
growing at the age of 6-12 years. This golden era comes only once, so not to be missed. Therefore, Baruna Bahari
Nature School intends to cultivate the spirit and love of their nature, particularly in the maritime field. With
examination of children development aspects and some surveys of primary schools in Jakarta and elsewhere, this
project is resulting in a natural school design that allows learners to freely explore, along with a slight
deconstructed typology of general elementary school in Indonesia. The harmony of exterior and interior creates
limitless space, with deep consideration to physical, cognitive, social, and emotional aspects in children, so that
students have a high fighting spirit, active, and creative.
