Mega Waty — Thu, 31 Aug 2023 00:00:00 +0000

During construction, change orders often occur. Change orders that occurred in 10 road construction projects in the
DKI Jakarta province were calculated by the job change index. The biggest job change index was in structural work
(88.768%), and the average index of additional work changes in asphalt pavement was 77.28%. Producing the largest
added job change index in drainage work (26.31%) and less job change index of 87.6% in road performance
maintenance work. Also produces the largest average change in return on minor conditions of 107.35%. The technical
reasons for the change order in these 10 projects are: Spec and design change group, scope change group, disruption
of the project operations group, contract document discrepancies group, incompetent consultant group, document
delays group, and client financial changes, and the last is the lack of coordination with the authorities. Initiators causing
change orders are contractors, owners, other parties, and consultants.

Kevin Adrian, Wilson Kosasih, Lithrone Laricha Salomon — Thu, 31 Aug 2023 00:00:00 +0000

In the last four years, the price of fabric raw materials has increased globally supported by fluctuations in the price
of the Dollar exchange rate causing the costs required by textile companies to increase by 81.97%. Based on
production data obtained from the company, product quality decreased by 10.28% from 2019 to 2022. Poor product
quality accompanied by increasing costs of production raw materials adversely affect company finances, so this
study aims to reduce the costs required in the production process. The cost of this production process can be
reduced by reducing the waste that occurs during the production process. To deal with this problem, this research
was conducted on one of the textile companies in Indonesia that produces fabric. The research began by identifying
the existing waste problem by conducting a special questionnaire survey called waste assessment questionaire
(WAQ). The respondents in this survey were three people from the textile company who were responsible for the
course of the fabric production process in the factory. The results of this questionnaire were used to model the
relationship between the types of waste and the types of waste that occurred the most. The results of data analysis
showed that there were four types of waste that significantly occurred, namely idle time by 23.9%, unnecessary
processes by 20.7%, waste due to product defects by 20.1%, and waste due to excess production by 18.9%. These
four types of waste will be further analyzed to eliminate the waste effectively and efficiently.

I Wayan Sukania, Lamto Widodo, Fanny Lorensa, Jennifer Juyanto — Thu, 31 Aug 2023 00:00:00 +0000

Every consumer wants a quality product. Likewise, consumer needs for quality tote bag products.
A quality tote bag describes the suitability of the specifications of the tote bag with the needs and
desires of consumers. Research to improve the quality of tote bag products was conducted at an
MSME in Indonesia that sells tote bag products in one of the largest marketplaces in Indonesia.
Based on the results of the initial data collection, information was obtained that the quality of the
tote bag could still be improved. Therefore it is necessary to do research to produce a better tote
bag design. The Quality Function Deployment (QFD) approach is used to improve the design and
specifications of the tote bag product. The research began by gathering information from
respondents regarding the needs and desires regarding the tote bag product. The needs and desires
that have been identified will become the basis for the development of tote bag products using the
House of Quality (HoQ) method. Through the design stages produced several concepts to be
selected according to predetermined criteria. Two types of tote bag designs were prototyped to be
assessed by consumers. The survey results prove that consumers prefer the newest tote bag product
compared to the previous tote bag product.

Frederico Fitz, Viny Christanti Mawardi — Thu, 31 Aug 2023 00:00:00 +0000

The use of point-of-sale cashier systems in commercial companies is still limited to using networks and
computers in some areas of the store, resulting in transaction performance being suboptimal when customer traffic
is high. However, the lack of speed in cashier machines serving customers forces them to wait for a long time in
front of the cashier counter, making it difficult for other customers to see products while shopping and disturbing
their comfort. The purpose of creating a barcode in mobile-based point-of-sale is to distribute cashiers throughout
the store to facilitate customer purchases and add cashless features that will reduce expenses such as computer
repair costs and monthly electricity bills.
The mobile-based point-of-sale application is created in the Dart language using the Flutter platform and Visual
Studio Code to write the code. The result of this application is a mobile point-of-sale display that can conduct sales
transactions simply by scanning the barcode to obtain the product code, followed by size selection and finally the
last transaction, which is cashless payment. This can make it easier for customers to avoid waiting too long and
reduce crowding in the store during peak hours. This application can also be connected to a Bluetooth printer to
easily send receipts and issue payment receipts efficiently, smoothly, sophisticatedly, and quickly

The development of automation in the industry is accelerating rapidly. The presence of automation is a technology
that is very helpful in increasing production. Automation cannot be separated from the existence of a control system
to regulate or process an instruction or order. The Modular Production System is a station unit consisting of various
types of stations that simulate production system designs on a small scale before being realized in real situations. The
work process of the Modular Production System is controlled using a PLC. PLC needs to be programmed to manage
the work process of the Modular Production System. The programming language commonly used in PLC
programming is ladder diagrams. The existence of a control system on the Modular Production System using PLC
will make the Modular Production System run automatically. It can communicate with other Modular Production
Systems to become more efficient. Therefore this design discusses controlling the Modular Production System using
a PLC with a ladder diagram. The distribution stations and pick and place stations are selected for the Modular
Production System. With a control system on the Modular Production System distribution station and pick and place
station, the Modular Production System can work automatically and communicate with each other between stations.

Sukhwinderjit Singh, Hadian Satria Utama, Joni Fat — Thu, 31 Aug 2023 00:00:00 +0000

Smartphones have become an integral part the lives of individuals and their priorities The present moment. The most
visible uses are to chat and chat programs Most of these apps do does not provide the necessary protection and
privacy information exchanged between users. Chat apps have become one of the most important and popular
smartphone apps. It has the ability to exchange text messages, images and files that can freely communicate with each
other. All messages must be protected and in this paper the encryption to used for secure all messages is by using AES
encryption. AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used to keep data
confidential in Internet networks. AES uses a block cipher with a block length of 128 bits and can encrypt data with
keys consisting of 128, 192, or 256 bits. AES is one of the strongest encryption algorithms available today. It has been
adopted by many organizations, including governments, banks, and technology companies. AES security is based on
mathematical complexity and is difficult to crack even on ultra-fast computers. The AES encryption process involves
multiple steps such as replace, move, and merge. The original data is split into smaller blocks and encrypted with the
provided key. The blocks then change periodically, complicating the data patterns an attacker might find

Dheanatasya Truece Rumangun Weripih, Endah Setyaningsih, Hadian Satria Utama — Thu, 31 Aug 2023 00:00:00 +0000

Waste is still a problem that is often faced in the community, the accumulation of waste in the environment must be
overcome with good management, because if not it will have a negative impact on all components of life. Waste
problems still often arise due to the habits of people who still throw garbage out of place, so that the existingarbage
becomes scattered in several places that cause a very pungent odor, even triggering flood disasters. The problem
that is difficult to handle is the placement of metal and non-metal waste, if the two wastes are mixed, it is difficult to
manage the two types of waste. One solution that can be applied to the trash can is to make a trash can that can
separate the location of waste according to its type, namely metal and non-metal. The innovation of a trash can that
can detect objects and the cover automatically opens, then the garbage will be sorted into metal and non-metal
waste based on a microcontroller aims to provide convenience to everyone who will throw away garbage by
automatically separating the types of waste. Using the processing module in the form of arduino nano as the
processing center, the sorting module in the form of an inductiv proximity sensor as a metal or non-metal detector,
the object detection module in the form of an ultrasonic sensor as a distance detector, the drive module in the form
of a servo motor as a garbage cover drive and a metal and non-metal garbage separator bar drive. A healthy
environment will encourage people to live healthy and realize a clean environment by creating a sense of "concern"
for the importance of environmental cleanliness and body health without waste

Artificial intelligence is on the rise and has undergone massive growth in the industry, especially in computer
vision. The emergence of computer vision from autonomous cars, robotics, surveillance, and many more has led
to challenge Artificial intelligence's confidence accuracy in detecting an object. Many artificial intelligence
algorithms are used by the industry, one of them is You Only Look Once version 8 (YOLOv8). YOLOv8 is a deep learning model for object detection. YOLOv8, which is developed by Joseph Redmon and Ali Farhadi is a powerful
method to detect an object in real time because YOLOv8 has the capability of processing high-resolution images
at high speeds. The research discusses about accuracy YOLOv8 in detecting object with a certain distance from
far to very close distance. The dataset is used to train the model of YOLOv8. The dataset is collected by taking
photos of an object with constant lighting but different distances. This research aims to obtain the most effective
distance that the YOLOv8 computer vision algorithm model could detect. The hipothessis is there is connection
between distance and detection accuracy of YOLOv8. If the distance increases, the detection accuracy decreases.
However, if the object is close the detection accuracy increases. So based on the results, a conclussion could be
concluded that a YOLOv8 model would have the highest accuracy at a certain distance.

stages of Cadman and Topping to anticipating possible risks and looking at alternative development scenarios under
the influence of a pandemic, and developments’ digital technology. The case study that will be taken in this paper is
the LRT CITY Ciracas Project in Jakarta, which is an Apartment and Retail complex project developed with the
TOD concept or Transit Oriented Development, where the project complex is directly connected to the LRT CITY
Ciracas station. The property development process is complex and high risk. Land value-oriented developers will
create development scenarios that seek to analyze the best land value to be developed in accordance with the
regulations and market needs at that time by presenting innovative designs or superior designs that meet feasibility
studies and are presented with development stages that can also maximize land value. The Evaluation stage is the
deciding point where the developer can make a decision to move forward until the development is complete, even
though there are difficulties and risks that might hinder the development process that must be faced or the developer
can decide to back off and change his development plan. In addition to risk, developers need to take into account the
development steps so that unexpected things do not arise.

AVOID FORGETTING TO PRESS THE LEFT SIGN BUT TURN RIGHT WITH SMART LIGHT-TURN SIGNAL (SLTS)

Lamto Widodo, Lina Gozali, Cherry Atmodjo — Thu, 31 Aug 2023 00:00:00 +0000

Turn signal lights function to give a signal when a motorcyclist wants to turn right and left or when overtaking other
motorists. By turning on one side of the light, right or left, it gives information to the riders behind and in front that
you want to turn. Some of the factors that cause drivers to forget to turn off the turn signal are a lack of
concentration and the color of the turn signal indicator during the day is less visible. Turn signal lights that stay on
cause confusion for other motorists. Confusion of other drivers can break the concentration of road users and cause
traffic accidents. The method used in this study is the distribution of questionnaires and design based on the
Analytical Hierarchy Process. The “Smart Light Turn Signal –SLTS”Mirror design consists of 4 alternative
variants. The chosen alternative is the fourth alternative. The selected product is then prototyped and implemented
on the user's motorcycle. As a result, most users no longer forget to turn off the turn signal

PRINCIPLE STRESS IN SHEAR CAPACITY

Thu, 31 Aug 2023 00:00:00 +0000

The design and construction of reinforced concrete high-rise building structures are currently changing for the better,
this is due to technological advances in the base materials of concrete that leads to a higher quality. A higher quality
concrete in multi-story buildings can reduce the cross-sectional dimensions of lateral resisting elements (earthquake
forces). Normal concrete is formed from aggregates (coarse + fine) and paste (a mixture of cement, sand, water, and
additives) in general. High-quality concrete is achieved through the use of innovative materials such as steel fiber.
Additionally, to form ultra-high concrete, it is made to be close to homogeneous. For this reason, the use of coarse
aggregates is eliminated, hence fine aggregates can blend perfectly with cement and other innovative ingredients to
form a concrete paste with higher strength than coarse aggregates. Concrete structural elements cannot be separated
from shear problems. Shear forces generally combine with bending, torsion, and axial forces. Therefore, it is
important to understand the interaction between shear and other forces.

DETERMINING THE CAPACITY OF A PILE WITH THE CONDITION OF ENCOUNTERING SOIL WITH MANY LENSES

Thu, 31 Aug 2023 00:00:00 +0000

In a structural construction, one of the important parts that need to be made to support the structure is the foundation.
The foundation plays a crucial role, so if there is a settlement in the foundation of a structure, an investigation is
needed to address it. In a project in Serpong, South Tangerang, there is a case where there is a layer of soil with
lenses, which is a condition where there is a hard soil layer with an N-SPT value greater than 50 and a thickness of
about 1-4 m, this hard soil layer is located between two layers of soil with an N-SPT values less than 50. The presence
of these soil lenses, located at depths of 8 m, 14 m, 24 m, and 42 m with varying thicknesses, cannot be identified
through the Cone Penetration Test (CPT) and is feared to cause a settlement in the pile foundation. This is because
the maximum capacity of the cone penetration test is only up to 2.5 tonf and cannot penetrate these soil lenses. This
research uses soil data in the form of two boring log data, which will then be analyzed and compared for the axial
bearing capacity and the settlement that occurs if the foundation piles occupy each soil condition that has a soil lens
layer. The Meyerhoff and Hanna method is used to calculate the ultimate bearing capacity, while the Alpha
Thomlinson method is used to calculate the settlement.

The foundation becomes an element that receives forces from the building construction above, channels, them to the
subsoil, and serves to support the building so that there is no structural failure from the bottom. The sole foundation
itself is a foundation that supports structures directly on the ground whose depth is arguably shallow, or generally at
most 3 meters above ground level. This shallow foudndation is analyzed and designed in such a way as to be able to
support a two-story house building with soil conditions that are former rice fields. This research starts from analyzing
existing case studies. Before proceeding with the data calculation process, it is necessary to understand the basic
theory and also the formulas that will be used in this research. Afer that, the data calculation process and sondir test
results were carried out, which can be concluded that the dominant soil is dense clay. Therefore, a shallow foundation
is still feasible to use for lower structure. Next thing is to do the planning and calculation based on bearing capacity
and settlement permit. The planning results will then be analyzed to determine the coefficients used in determining
the costs in the use of shallow foundations. In this study, the cost calculation that has been carried out has a total of
Rp 119,678,664.38. From the total costs, it can be concluded that the use of shallow foundations still makes sense and
is one of the best options in the construction of this two story house

FINDING THE OPTIMAL REINFORCEMENT FOR VERY DEEP BORED PILE FOUNDATION

Gregorius Sandjaja Sentosa, Aniek Prihatiningsih, Kilian Rohan, Ricky Putra — Thu, 31 Aug 2023 00:00:00 +0000

The foundation is the most important part of any structure in the construction process. A failure in the foundation
can cause the entire structure to fail if cannot withstand the forces or weight of the structure above. The foundation
is required to bear the external loads or weight of the structure, even though the upper structure may be strong and
sturdy. Bored pile foundation is the most commonly used foundation type for building projects or multi-story
structures. The distribution of forces on pile foundations is inversely proportional to its depth, and the part of the
pile close to the forces will bear a greater load than the deeper part of the pile. This consideration makes the design
of reinforcement for pile foundations variable according to the distribution of forces acting on the pile according to
its depth. This study analyzes the reinforcement requirements for a pile foundation using laboratory-calculated soil
parameters and data specific to the Jakarta area. The first step is to determine the soil parameters, then calculate
the force diagram using the Matlock and Reese method, and finally, determine the reinforcement requirements
based on the force diagram obtained. After that, the calculated reinforcement needs to be adjusted according to the
applicable requirements for a pile with a length of 65 meters and a diameter of 1800 mm. The required
reinforcement is D13-75 for transverse reinforcement, 20D32, 16D29, and 8D32 for longitudinal reinforcement
according to their depth.

The Triangle Hedging Robot or Expert Advisor is designed for the MetaTrader 4 (MT 4) platform. The robot can monitor signals, open positions, close positions both for each currency pair and as a whole. The robot is also designed to be able to run automatically or semi-automatically. The robot is implemented in the foreign exchange (forex) market for the EURJPY, GBPJPY and EURGBP pairs. Position opening is based on technical analysis using the Moving Average (MA) method. A Buy position will be opened if there is an upward cross from the small period MA to the big period, and conversely a Sell position will be opened if there is a downward cross from the small period MA to the big period. The robot works based on two cycles that have been defined, namely the first cycle in the form of buying EURJPY, selling GBPJPY and selling EURGBP; and the second cycle is selling EURJPY, buying GBPJPY and buying EURGBP. Each cycle is a complete position of Triangle Hedging. Robots can also work with user interaction. If the user opens a position with a certain lot size, the robot will perform lot calculations and determine cycles to hedge properly. The results of testing the robot show that the robot works well according to its purpose. It's just that the robot still needs to be tested more intensively to determine whether the robot can provide benefits for the user in the medium or long term.
