Abstract

Most tofu producers still use steamers as boilers, which poses a risk to tofu quality. To reduce the risks and losses caused by this, a safe boiler construction is designed according to ASME (American Society of Mechanical Engineers) design standards. This research uses a Research and Development (R&D) approach supported by software capable of analysing model characteristics. The boiler construction was designed according to the ASME (American Society of Mechanical Engineers) standard, then the boiler design was created using Autodesk Inventor and a theoretical analysis was conducted using internal pressure loads to evaluate stress and displacement in the boiler construction. The results of the study obtained the specifications for a horizontal type of boiler with an operating steam pressure of 2 bar and a design pressure 4 bar. Boiler dimensions 600 mm in diameter, 1200 mm in length. Fuel uses firewood and the maximum volume of water that can be filled in the boiler is up to 113.1 litters. The material used for the plate is 5 mm stainless steel plate 304.

Abstract

The rapid evolution of technology has transformed the automotive industry, transitioning from internal combustion engines to electric vehicles (EVs) to reduce greenhouse gas emissions and dependence on fossil fuels. This study focuses on developing a body electrical system for electric motorcycles by integrating components like lead-acid batteries, pulse-width modulation (PWM) controllers, waterproof DS18B20 temperature sensors, DC-DC converters, and energy-efficient LED lighting. The system is designed to comply with Indonesia’s National Standards (SNI). Employing the 4D research methodology (Define, Design, Develop, Disseminate), the electrical system underwent rigorous validation and testing. Results highlight enhanced performance, improved energy efficiency, and effective thermal management. The integration of a temperature control system reduced the risk of overheating, ensuring safety and operational reliability. This research contributes to advancing EV technology, offering a framework for optimizing body electrical systems for electric motorcycles in compliance with safety and performance standards

Abstract

The increasing volume of hazardous and toxic waste (B3), particularly from used cooking oil, poses significant environmental and health challenges. One promising solution is converting this waste into biodiesel, thereby promoting renewable energy development while reducing ecological risks. This study investigates the yield percentage of biodiesel produced from waste cooking oil using a magnetic stirrer. The research aims to determine the optimal stirring duration to maximize yield and evaluate the flame duration of the resulting biodiesel. The process involved tool and material preparation, biodiesel production via transesterification, and subsequent data collection and analysis. The findings revealed that the highest biodiesel yield, 58.4%, was achieved at a stirring duration of 45 minutes, whereas the lowest yield, 51.2%, occurred at 60 minutes.

Abstract

The demand for crude oil continues to increase in line with expanding needs, but this contrasts with its limited availability in nature. The oil and gas industry is one of the key sectors in the global economy, encompassing exploration, refining, processing, transportation, distribution, and sales. Given the high-risk working environment, safety is a crucial factor that must be considered. In recent decades, numerical methods have been widely used to enhance the effectiveness and efficiency of safety analysis, particularly in risk identification, equipment condition monitoring, and optimizing hazard mitigation strategies. This report discusses the application of numerical methods in improving the quality of planning, maintenance, and failure mitigation of various components and infrastructure at PT Pertamina Patra Niaga Fuel Terminal Boyolali. The study focuses on MOV with the friction coefficient between the stem and stem nut, pipeline systems concerning corrosion in elbows caused by chemical compounds carried by oil, and storage tanks related to temperature control within the tank to maintain the quality and quantity of oil as per demand. A comprehensive study shows that lubrication can limit the friction coefficient in MOV, while viscosity is a significant issue in pipeline systems and storage tanks. Numerical approach methods can improve the energy industry's safety, reliability, and efficiency. Modeling can reduce costs, time, and worker safety risks compared to experimental approaches.

Abstract

Microhydro power plants (MHPP) are a potential renewable energy solution for remote areas that have abundant water resources. However, monitoring the performance of MHPP systems in these areas is still a challenge, especially in terms of reliability and energy conversion efficiency. This research aims to design and develop an Internet of Things (IoT)-based monitoring system capable of monitoring real-time voltage and current in MHPs. The system was tested using the Archimedes Screw turbine in a laboratory-based test scale, and a literature study was conducted to compare the effectiveness of several types of micro hydro turbines such as Pelton, Crossflow, Turgo, and Archimedes Screw. The results showed that although the efficiency of screw turbines is relatively lower, they are suitable for use in locations with low head and stable water flow. The 4D approach method was used in the development of this monitoring system, and the results show that the system is able to provide accurate data and support the improvement of MHPP operational reliability.
