Based on the necessity to improve the fabrication and assembly of a gravimetric dosing system, an automated testing system, based on Hardware-in-the-Loop (HiL) simulation, has been developed to assess its Factory Acceptance Testing (FAT). The developed testing system consists of (i) a limited real-time HiL simulation and interface implemented with off-the-shelf components, (ii) a user interface for defining the test automated execution, and (iii) a verification engine for the automated collection and validation of the test. Although experimental, the adopted testing system architecture proved sufficient for the specified test procedures, while the modularity of the implementation could prove beneficial for further applications. The proposed setup is able to recreate the real system behaviour along the necessary process parameters, which was proofed by computing the correlation coefficients between real-world data and the simulation.

Pati has a high certainty of raw material supply but Pati salt farmers experience quality and price problems. Currently, there is another potential high-value salt, namely as an energy source (Cathode battery). To solve this problem, the cathode terminal was built by considering the existing sand. Supply chain network design (SCND) is one of the most important strategic decisions in supply chain management. This paper presents novel research on the network design of a simplified single product multi farming and multi-terminal for salt raw material in cathode battery. The proposed optimization model minimized cost to determine the location of the cathode battery terminal by using Lingo Sofware. This paper will explain when the terminal opened and any farmer delivery salt raw material. This study develops a mathematic model for making a decision cathode battery terminal opened by mixed-integer linear programming (MILP). The result shows terminal 1 (Z1) receives a greater supply of raw materials and the least received supply from farming is terminal 3 (Z3).

Human-machine collaboration (HMC) has been a growing trend in research and real-world implementation. Many manufacturers started to integrate the robot into their production line and able to collaborate with the human. The aim is to boost the production system performances by taking advantages of both human and robot. However, the human-machine collaboration required a comprehensive design to make sure the system run well, thus enhance the production system productivity and efficiency. This paper elaborated a human-machine collaboration design for a cartoys assembly line. The design is modelled by using discrete event simulation (DES) approach. The simulation goal to give picture and prediction regarding system performances and behaviour from the HMC assembly line design. Several sequencing rules are applied to the system's resources. Comparison between sequencing rules and Pareto Frontier analysis are conducted in the study to give insight regarding the system performance and to obtain the preferable sequencing rules that applied to the resources. The result is sequencing rules provide a significant effect on system performances such as resources utilization, throughput, and flow time. The most preferable sequencing rule for the assembly line has been identified.

Indonesia has a high potential of solar energy due to its location on the equator and in this paper, experimental testbed for PV-Battery hybrid system is developed and discussed. The hybrid system is designed to supply electricity during the night time with on-grid inverters. Practical and inexpensive solar PV-Battery hybrid system was developed and tested in Tangerang area with flexible AC electric production during the daytime as well as the night time. Practical issues for hybrid system were discovered such as limited range of inverter output voltage, sensitivity of solar panel electric production to its position and shading, accurate DC current sensor, cable and component overheating, lower inverter conversion efficiency than what specification states, safety on charging Lithium-Ion battery. Conclusions from this study are that wet battery seems to store more electric energy and more robust than the free maintenance battery, battery voltage is not a good indicator for battery level of charged, solar panel electric production is sensitive to its position and clearness from the shading, measurement of cable and component temperature is needed to justify enough cable size to deliver designed electric power, enough capacity of the component and quality of connections, care need to be taken when Lithium-ion batteries are used due to possible explosion for too high charging current.

Risk is an important factor that determines the success of mobile application development. Identifying risks will help developers minimize failures. Likewise, the determination of risks that affect usability can support taking preventive action before failure occurs. Previous researches have shown that many risks have been identified in mobile application development. However, it is rare to determine usability risks in mobile applications. This study aims to identify the risks that affect the usability of mobile application users. This study uses a literature study with several stages, namely: identifying a combination of usability attributes, identifying risk factors (potential risks), and determining the potential usability risk of each usability attribute at each stage of information system application development. This study resulted in 8 usability attributes, 107 risk factors (potential risks), and usability potential risks for each usability attribute at each stage of mobile application development. The results of this study can also determine the usability attributes that affect each phase of mobile application development.

The first job search time is one of the measurement values of a university, an "A" accredited university if the average time for a student's job search is less than three months. According to the Telkom University tracer study in 2016-2018, there was a significant increase of students who experience the first job search time for more than three months from 18% up to 54%. The purpose of this study is to classify which students will have the potential to experience the first job search time for more than three months based on tracer study, history of organization type, position, Grade Point Average (GPA), and remaining semester credit units. With the results of using the classification process with decision tree C5.0 algorithm, the model has accuracy 54.7% with three attributes that are considered, GPA, study period, and participating in educational/reasoning/arts organizations. This helps Telkom University in monitoring students who are indicated to be experiencing a short or long first job waiting time. Therefore, Telkom University can provide specific activity recommendations for students, based on their GPA, remaining semester credits, and organizational activities. For further research, it can be more variables can be added to develop a model with higher accuracy.
