Published: July 2020

Abstract
The connection systems of wood structures, which are often observed in Indonesia, mainly utilize bolts or nails, whereas a similar system with bolt-ring connectors is quite rare. In fact, in other countries like U.S., Netherlands, etc., such a system is commonly implemented, especially for the constructions of wood buildings which require a large capacity or a relatively large building. To show that the system also potentially excels when used for wood materials in Indonesia, especially in comparison with the ordinary bolt connection system, several empirical tests of the connection systems with materials from Mahogany wood (Swietenia spp.) were conducted. This experiment implemented six connection systems under compressive tests in order to investigate the compressive strength behavior of bolt-ring connections compared with the bolt connections. From this study, it can be concluded that the bolt-ring connection system yields better compressive strength behavior and performance than the bolt connection system. However, if used in connections with single ring, it is necessary to be careful when they are subjected to compressive loads. It is due to the connection system which may undergo rotations which can cause the system to be unstable. If stability can be safely maintained by adding some steel plate holder; then, the system will become more superior to the simple bolt connection system, in terms of compressive strength, stiffness, and ductility.

Published: July 2020

Abstract
Indonesia is a tropical country that has two seasons, dry and rainy seasons. Now this season in Indonesia is difficult to predict because of the effects of global warming. The effect of global warming is quite disturbing activities of human life, one of which is in the case of drying clothes. Then an automatic clothes dryer cabinet was made with Wi-Fi transmission media making it easier for humans to find out information in the cabinetremotely using a smartphone. The system starts when the voltage supply is turned on and the fan turns on and the other system is in standby. When the clothes are in the cabinet, the heater will turn on and the microcontroller will send information about the situation in the cabinet. The heater will turn off when it has reached the set temperature to prevent excess heat in the cabinet. Clothing weight information will appear on the smartphone through the application, if the weight of the clothes has reached <190 grams, then the clothes notification will appear dry and turn off the system on the application. The weight sensor has a role to activate the digital thermostat which has a temperature sensor to disconnect and connect the power to the heater.

Authors: Setiawan C S , Gondokusumo O 
Published: July 2020

Abstract
Preliminary cost is a support cost that needs to be done so that the construction project can run well, but costs tend to experience an increase from the planned cost that has been determined to the final cost. Preliminary cost affects profits or losses of a construction project, therefore this study is essential so it can be known the reference for preliminary cost and cause of cost overruns, which items that give a high contribution to the preliminary cost, and the relationship between preliminary cost and profit at company XYZ. At Sumatra, Kalimantan, and Papua, the actual preliminaries cost occurs by 215%, 114%, and 188% from the planned cost, thus the cost overruns happened. The cause of this cost overruns can occur because of lack of skill of the estimator for estimating and planning about cost, duration, equipment and tools, miss implementation of method statement, lack of information about the project, incomplete design, and unaquired land. The component of the preliminary cost is vary based on its location. This analysis is necessary because it can show which items are influential and contribute a large proportion to the overall preliminary so that more attention is given to those items. The preliminary cost has a contradict relationship to profit, if the preliminary cost is increased, the profit will be decreased.

Published: July 2020

Abstract
Swirling flow at recirculation zone of backward-facing step (BFS) geometry undoubtly affected by Reynolds number since it is involving rotational vortices. This flow behavior can be represented by flow intensity and reattachment length inside the geometry. BFS geometry is chosen for it is well-known characteristics visualizing swiriling flow that occur in many industrial application. Unfortunately, experimental method for visualizing rotational vortices over a BFS geometry oftenly involve advance technology including the image capturing devices. CFD method is use in this research for computionally visualize respected flows with Reynolds number variation with lower cost. The model is 3 dimensional with Step height (h) = 41mm, upstream height (H) = 81mm, expansion ratio = 1.5, total length (L) = 4050 mm and width = 20h. The mesh is triangular with 90.293 nodes. Reynolds numbers varied to Re = 4290.39; 6673.94; 7614.23; and 9287.29 which gained from experimental data. The working fluid is single phase air, with inlet and outlet temperature also gained from experimental data. The initial fluid temperature at inlet and outlet are 28.4°C and 28.8°C; 27.3°C and 28.6°C; 26.2°C and 28.3°C; 28.7°C and 29.8°C for respected Reynolds number variation. The flow condition is assumed transient with time step set of 1 and simulation is done with STD k-ε turbulence model. Highest Reynolds number variation reattached at reattachment / step height X/h = 6.82, compared to Re = 4290.39 with X/h = 11.71. CFD simulation results show that eddies inside the vortices and the X/h affected by floe velocity and so on with the flow temperature.

Published: July 2020

Abstract
Currently autonomous vehicles are equipped with a variety of sensors, controls and actuators, depending on the objectives and requirements of the vehicle. One of the biggest challenges in the development of the autonomous vehicle system for the assistance in the movement of people with visual disabilities is the high cost. Therefore, researchers with a limited budget carry out their experiments and research in simulation environments, while other researchers use small vehicles that in many cases do not accurately represent a real parametric dynamic system. This article describes the design of a low-cost prototype of an autonomous electric vehicle that includes its control systems, microcontrollers, encoders, motor controllers, sensors and cameras. Therefore, the designed vehicle has the ability to move autonomously through the use of vision and artificial intelligence algorithms to assist in the movement of the visually impaired person. The document details the first steps of the design taking into account the parameters of a real environment and artificial intelligence algorithms.

Abstract
Compressor companies in the Bogor area, planning of purchasing raw materials and planning for production are based on direct orders from customers. Sometimes customers make sudden orders or increase the number of orders, so companies must change production schedules and order additional raw materials from suppliers. Not all suppliers can meet the sudden demand of the company. Compressor raw materials and other supporting raw materials often experience delays. This study aims to mitigate the causes of supply chain risk to eliminate and minimize company losses. The mapping of the company’s supply chain activities is based on the SCOR. After risk identification, risk assessment is carried out to determine severity, occurence, and correlation. Furthermore, the ARP value calculation is performed to determine the ranking and risk prioritization. Determination of risk prioritization using the HOR method. Based on the Pareto table, the highest ARP value is above 80%, there are 2 causes of risk A1 and A2 that contribute as much as 86.55% of the total ARP supply, the causes of the risk are: A1: Sudden order addition and A2: Breakdown of internal and/or external communication. These two causes of risk are the priority for prevention by the company.

Published: July 2020

Abstract
This paper discusses how to build a network interference notification system by integrating Telegram messenger. The problem faced is that when the system has not been integrated, a technician must check for interference based on complaints faced by the customer. After getting a disturbance report from a customer, a technician must check one by one to find out the disturbance. This is of course time consuming and inefficient. So, to facilitate the performance of technicians and to improve service, the system that was previously manual is integrated using a notification system that is integrated with Telegram. This system will automatically provide notifications through periodic checks conducted by Netwatch. Testing is done using simulations using virtual machines and GNS3. The results of this paper are a website-based application and Telegram-based messenger that are ready to be implemented on a real network.

Published: July 2020

Abstract
Along with the diverse types of electronic goods and digital evidence, techniques have also developed in conducting digital forensic investigations. Another effect is the increase in types and types of tools for conducting digital forensic investigations. The problem is the increasing number of digital forensic tools is not always developed in conjunction with the manual book. So this is what makes the investigator to check the tool to make it suitable for investigations. Choosing the right tool is very important in the investigation process, because each stage of the forensic investigation process has a different treatment for each of its staging. Seeing these conditions, then in this paper we make a system design to facilitate investigators in choosing the right digital forensic tool and in accordance with using an expert system. The design system shows that it’s still needed to confirm to an expert to get a match output if there is a new rule. Later this system will be implemented with website technology.
