Abstract

The burgeoning interest in low-emission mobility has led to a focus on Hydrogen Refueling Stations (HRS) in developing nations such as Indonesia. This study, unique in its assessment of the techno-economic feasibility of two distinct HRS configurations, delves into the cascade storage system, which involves storing hydrogen in a series of pressure vessels, and the booster compressor system, which utilizes a compressor to elevate the hydrogen's pressure. The evaluation considers projected daily demand scenarios of 413 kg/day and local economic factors adjusted for inflation. A meticulous and comprehensive discrete event simulation model was developed to encapsulate the operational dynamics inherent in each scenario under consideration. This model, which incorporates key factors such as fueling time, cascade priority logic, and hourly vehicle arrival patterns, ensures that the audience is fully informed and knowledgeable about the study's findings. In conjunction with this, an economic analysis was conducted employing the robust Levelized Cost of Hydrogen (LCOH) and Rate of Return (ROR) frameworks. The study utilized specified financial parameters, including a 5.75% real discount rate, a 15-year analytical horizon, and cost adjustments to reflect the 2025 Indonesian Rupiah. The model aims to provide a robust understanding of hydrogen fueling systems' economic viability and operational efficiency in the specified context through these methodologies. The results show that the cascade system yields a lower LCOH (IDR 41.017/kg) and capital cost per kg compared to the booster system (IDR 70.833/kg). However, both reach breakeven within 9.5 years. The booster is less advantageous in smaller-scale deployments because of its higher compression efficiency and capital investment requirements. The higher requirement for capital investment and compressing efficiency. The economic feasibility of HRS configurations may be considerably enhanced by methods to boost hydrogen sales and control capital expenditure, providing a bright future for hydrogen fueling systems.

Abstract

The world is entering industry 4.0. The digital enlarges to machine maintenance known as troubleshooting. Troubleshooting is a series of actions needed to deal with machine damage treatment. Problems that often occur in troubleshooting are that technicians are not in the location, the information is still in the form of printed books, the risk of books being lost, books slipping, and the location of books far from the location of machine failure. This research was to solve this problem by developing an application called Production Machine Troubleshooting Information System (SITMEP) in relational database environment. This system was developed by integrating several methods such as machine damage knowledge obtained from tacit sourced from mechanical technicians, experts in their fields and explicit knowledge sourced from machine manual books. GT is to combine knowledge with machine hierarchies and it supports systems for database and SQL. The tool used was MS Access with VBA.

Abstract

This journal presents the development of the Material Tracking Application at PT. Pindad. During the assembly process, some components may be rejected due to defects or non-compliance with other components from different suppliers. It is difficult to identify the origin of rejected components due to the lack of rejection data from each supplier. This issue led to the development of applications that can trace the origin of components by attaching QR codes to packages. Scanning the QR code activates the Quality Function to identify the origin of the component. QR codes were chosen because of their cost-effectiveness, low operational costs, and ease of reading compared to other Automatic Identification Procedure (Auto-ID) technologies. Another problem is the administrative process when moving parts/components from the component warehouse to the production warehouse. The recording process still uses paper-based documentation which is time-consuming and error-prone. Therefore, QR codes are also used to simplify and speed up the recording process by the security function. From designing web-based applications which are then deployed and run on Google's cloud services. The researcher then carried out a testing process with 2 stages, namely the process of verification and validation. It was found that the Material Tracking Application went well according to the researchers' expectations. There are still many opportunities for the development of this Material Tracking Application. Mainly development using other Auto-ID and different case studies in the world of manufacturing.

Abstract

In the manufacturing industry, machining has developed quite rapidly from the use of conventional machines to unconventional machines. Unconventional machines that are often used today are optimize computer numerically controlled (CNC), the use of CNC in the manufacturing industry provides many benefits in product quality and productivity. One of them is CNC milling, this type is one of the main machines on the production floor. Machining optimization becomes the main goal to achieve the ideal response in order to produce products with good and consistent quality and productivity. Surface quality leads to surface roughness, while productivity leads to material removal rate. This study aims to optimize CNC milling machining parameters on AA6061 with Taguchi experimental design and preference ranking organization method for enrichment evaluation (PROMETHEE) method. Machining was controlled using wet machining conditions to maintain temperature during machining. Experiments were conducted nine times with three factors and levels. These factors included spindle speed, feed rate, and depth of cut.  The result of this research is the ideal value of the combination of surface roughness and material burning rate which is 0.565 (experiment 3). This best experiment is influenced by spindle speed 2600 rpm, feed rate 65 mm/min, and depth of cut 2.5 mm. Feed rate has the largest contribution in influencing the response which is 43.23%, followed by depth of cut 25.24%, and spindle speed 15.91%.
