Abstract

The Family Welfare Empowerment (PKK) is a community organization that plays a vital role in improving family welfare in Indonesia. Through various programs, the PKK contributes to family empowerment, particularly in education, health, and economics. However, many PKK activities are still conducted manually, including recording and managing member data and activities. This creates several challenges, such as difficulty in archiving, time-consuming information searches, and difficulties in preparing accurate and timely reports. This research aims to design and develop a web-based information system that can simplify member data management, activity recording, attendance management, and report generation more quickly, efficiently, and accurately. This system will be designed using an object-oriented approach, involving several stages, starting from needs analysis, system design, implementation, and system testing. This information system is expected to improve service efficiency, facilitate PKK administrators in monitoring member activity, and support a more precise and weighted data-based decision-making process. Another advantage is that this system will also facilitate the PKK in producing faster, more comprehensive, and more structured activity reports, thereby increasing organizational transparency and accountability. Therefore, this web-based information system is expected to be a solution to improve the PKK's performance in carrying out its function of empowering family welfare.

Abstract

The Decision Support Sistem (DSS) for selecting exemplary teachers at SMP Negeri 2 Loli aims to assist the school in determining teachers who deserve to be recognized as exemplary teachers. The evaluation of exemplary teachers involves various criteria such as teaching performance, discipline, creativity, and communication skills with students. However, the selection process conducted manually tends to be subjective and time-consuming. Therefore, a sistem is needed to simplify and accelerate the selection process while producing objective and transparent results. This sistem is developed using the Simple Additive Weighting (SAW) method, which is one of the techniques in multi-criteria decision-making. The SAW method works by assigning weights to each predetermined criterion and calculating the weighted scores for each alternative (teacher). These weighted scores are then summed to determine the ranking order of teachers who meet the criteria as exemplary teacher candidates. The results of this study indicate that the implementation of the SAW method can produce a more structured, objective, and efficient exemplary teacher selection process. The sistem facilitates the school in conducting evaluations and decision-making, while also reducing the potential for errors that may occur during manual selection. Thus, this decision support sistem is expected to make a significant contribution to improving the quality and accuracy of exemplary teacher assessments at SMP Negeri 2 Loli.

Abstract

The manufacturing industry in Indonesia has experienced significant growth. This increase has also impacted the demand for motorcycle spare parts. Currently, brake pads are composed of asbestos, which makes them prone to overheating and failure when reaching high friction temperatures. Therefore, an alternative brake pad material is an organic material mixed with coconut shell powder and bamboo fiber. This study aims to analyze the wear and hardness levels of motorcycle brake pads made from coconut shell powder and bamboo fiber. The study used varying ratios of coconut shell powder, bamboo fiber, and epoxy resin: 40:30:30, 35:35:30, and 30:40:30. Eighteen specimens were tested. Wear testing was performed using an Ogoshi Wear Tester, while hardness testing was performed using a Brinell hardness tester. The test results showed that the smallest wear rate on brake pads with variations of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin was 0.001107984 mm3/kg.m. The highest hardness level was also in the variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin at 63,0024 kg/. So it can be concluded that the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the lower the wear rate. If the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the higher the hardness level. So it can be concluded that a good brake pad variation is a variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin.

Abstract

This study aims to design a blanking die used for mass-producing mobile phone holders while prioritizing efficiency and dimensional accuracy. The die set developed includes key components such as the punch, die, stripper, guide post, and fastening bolts. The product produced has dimensions of 138 × 63 × 2 mm and uses ST 37 steel as the raw material. Based on calculations, the required blanking force is 129,000 kN, which is considered safe for the production process. The design also accounts for an optimal clearance of 0.083 mm and a die thickness of 35 mm to effectively withstand the working load. Simulations using stress analysis methods reveal that the von Mises stress distribution on both the punch and die remains below the elastic limit of SKD11 material. The maximum stress on the punch is recorded at 2.437 × 10⁵ N/m², while on the die it reaches 5.153 × 10⁵ N/m², both well below the yield strength of SKD11, which is 2.918 × 10⁸ N/m², indicating that these components operate safely without the risk of plastic deformation. To strengthen the construction, the stripper is designed with a thickness of 12 mm, and the addition of four SCM435 bolts is recommended to improve system stability. This die design is verified through manual calculations and Finite Element Analysis (FEA) to ensure its reliability. Overall, the findings of this study demonstrate that the designed blanking die can support mass production with high precision, optimal structural strength, and long-term durability.

Abstract

The purpose of this study is to develop an additional device for vehicles with fuel injection systems to improve fuel consumption efficiency and reduce exhaust emissions, even for older vehicles. The turbocyclone is an auxiliary component installed in the air intake duct before the throttle body to create a swirling airflow entering the combustion chamber. Testing was conducted at engine speeds ranging from 1500 rpm to 6500 rpm, with increments of 1000 rpm. This research aims to minimize fuel consumption and exhaust gas emissions. The experimental method was used, testing exhaust gas contents such as HC, CO, CO₂, and O₂ using a gas analyzer, and measuring fuel consumption based on fuel volume and time. Data processing employed a factorial DOE (Design of Experiments) to analyze results. The dependent variables were exhaust gas emissions and fuel consumption, while the independent variable was the turbocyclone blade angle variations of 20°, 40°, and 60°. The results show that the best reduction in exhaust emissions (HC, CO, CO₂, and O₂) and fuel efficiency occurred at a 40° blade angle, whereas fuel consumption increased at a 60° blade angle.

Abstract

An exhaust pipe is a tubular device used to channel combustion gases from a vehicle’s engine into the environment. In addition to this primary function, the exhaust also serves to reduce the noise level produced by engine combustion. The component of the exhaust system that significantly affects torque, brake mean effective pressure (BMEP), and noise level is the silencer. This study aims to compare the torque, BMEP, and noise levels produced by variations in the length and construction dimensions of elliptical filter designs in the silencer. The silencers used in this research have lengths of 280 mm, 300 mm, and 260 mm, with short ellipse filter diameters of 25 mm and long ellipse filter diameters of 30 mm, 40 mm, and 50 mm. The research employs an experimental quantitative method, and the data were analyzed using one-way Analysis of Variance (ANOVA). The experiment was conducted in a Mechanical Engineering workshop using a Yamaha R15 V3 155cc injection motorcycle (2021), a Super Dyno 50L dyno test, and a sound level meter, from February to April 2024. The engine speeds tested were 1500, 2500, 3500, 4500, 5500, and 6500 rpm. The results show that the variation of ellipse dimensions 25 mm × 50 mm × 260 mm produced a maximum torque of 12.77 N·m at 4500 rpm, a maximum BMEP of 1021 kPa at 4500 rpm, and a noise level of 80.3 dB. The variation 25 mm × 40 mm × 300 mm produced a maximum torque of 12.88 N·m, a BMEP of 1042 kPa, and a noise level of 75.60 dB, while the variation 25 mm × 30 mm × 280 mm produced a maximum torque of 12.67 N·m, a BMEP of 1013 kPa, and a noise level of 75.63 dB.

Abstract

The development of embedded sistem technology is now widely used to support automatic environmental data recording processes, such as temperature, humidity, and air pressure. However, most existing weather data loggers still operate independently and are not directly connected to a computer. As a result, data collection and processing must be done manually, which is less efficient and prone to data loss. The main problem in this research is the lack of integration between microcontroller-based data loggers and simple computer operating sistems such as the Disk Operating Sistem (DOS), making it difficult to automatically store and access recorded data. This study aims to develop an embedded weather data logger sistem based on the AVR microcontroller integrated with DOS. The development process uses the waterfall model, consisting of sistem planning, requirement analysis, sistem design, coding, testing, and implementation. The designed sistem records weather parameters in real time and stores them in a file format that can be directly read by DOS without requiring additional conversion processes. The test results show that the sistem runs stably, records data accurately, and can be easily accessed through a computer. Integration with DOS allows data storage and retrieval processes to be faster and more efficient. Therefore, this sistem provides a practical solution for automatic weather monitoring that is reliable, time-saving, and easy to use in various environmental conditions.

Abstract

The limitation of physical memory (RAM) is a primary constraint hindering optimal performance in modern operating systems, especially when running large applications or performing intensive multitasking, often resulting in crashes and high latency. This research aims to quantitatively analyze the effectiveness of Virtual Memory (VM) implementation as a solution to this RAM constraint on the Windows 10 operating system, focusing on VM’s impact on CPU performance, GPU performance, and multitasking response. The methodology employed is a controlled experiment using industry-standard benchmarks: Cinebench R20 (CPU), Unigine Heaven (GPU), and response time measurements in intensive multitasking scenarios. Experimental results demonstrate that VM activation improves CPU/GPU performance by up to 5% and accelerates multitasking response time by up to 15%, confirming VM's effectiveness in mitigating memory bottlenecks. Nevertheless, this study also identifies potential performance overhead stemming from excessive paging and swapping processes, which trigger the phenomenon of Thrashing. Therefore, the research recommends a dual optimization strategy to achieve maximum and stable performance: software optimization via the Least Recently Used (LRU) algorithm to suppress page faults, supported by hardware optimization including the use of an SSD for the swap file and increased RAM capacity.

Abstract

In today’s era, we are very familiar with operating systems that function to manage the work of hardware and software so they can be used properly. One of the most widely used operating systems is Windows, because it has an easy-to-understand interface and is capable of running multiple applications simultaneously. To support this, Windows requires a process management mechanism, namely a way for the system to organize running programs so they do not interfere with each other and remain stable. In process management, there is an important component called the Process Control Block (PCB). The PCB can be likened to an identity card or a complete record of a process, as it contains information such as the process ID, status, CPU usage, memory, and files being used. This study aims to analyze the role of the process control block, focusing on how the Process Control Block stores important information regarding the status and activity of each process, ensuring smooth, efficient, and non-conflicting application execution. In this research, experiments were conducted to measure CPU usage, memory, and execution time by various processes with different priorities to observe the information of running processes. The analysis results show that each application has its own Process ID and PCB, which records status, CPU registers, memory allocation, and I/O resources used. The PCB enables multiple applications to perform multitasking effectively.
