Abstract

The automotive industry continues to evolve with the integration of sophisticated computational tools to optimize design, analysis, and control systems. MATLAB, known for its powerful numerical and simulation capabilities, has emerged as a key tool in achieving efficiency, accuracy, and automation across automotive engineering processes. This study explores the strategic utilization of MATLAB in areas such as engine modeling, vehicle dynamics simulation, embedded system development, and control system design. The research employs a qualitative method supported by case studies from various industrial applications, highlighting how MATLAB toolboxes like Simulink, Stateflow, and Simscape contribute to reducing development time and improving system performance. Results show that optimized MATLAB use not only accelerates prototyping and testing phases but also enhances precision in control strategies, especially for electric and autonomous vehicles. This paper concludes by emphasizing the growing importance of MATLAB proficiency among automotive engineers and its role in driving digital transformation in the industry.

Abstract

The global energy crisis and increasing awareness of the negative environmental impacts of fossil fuels have driven the development of sustainable alternative energy sources. One promising renewable fuel is bioethanol, especially when produced from agricultural waste such as young coconut waste. This study aims to evaluate the effect of using bioethanol derived from young coconut waste on the thermal efficiency of the Honda GK5 engine through thermodynamic analysis based on the Otto cycle model and verification using experimental data. The research method includes laboratory testing of the Honda GK5 engine with variations in fuel mixtures: E0, E10, E20, and E30. The test results show a significant increase in thermal efficiency up to the E20 mixture, with an experimental efficiency of 31.8% and a theoretical efficiency of 32.0%. This improvement is attributed to the high octane number of bioethanol, which supports more complete combustion. However, at the E30 mixture, a decrease in efficiency is observed due to the lower heating value of bioethanol. The Otto cycle model successfully represents the trend of thermal efficiency with an average deviation of 1–1.5% compared to experimental results. Therefore, bioethanol from young coconut waste proves not only to be environmentally friendly but also capable of enhancing engine energy performance optimally without requiring significant modifications.

Abstract

Micro Hydro Power Plant is a small scale power plant that uses hydropower as its energy source. The power to drive the PLTMH turbine is in the form of water flow originating from irrigation canals and rivers. The undershot turbine is a type of water turbine that utilizes river flow or irrigation channels as the driving force for the undershot turbine. In this research, based on the problems used in undershot turbines in order to get maximum results, the researcher designed a PLTMH prototype by analyzing the effect of the number of blades and the turbine blade model on the power produced by the generator in the undershot turbine of a micro hydro power plant so that it would be known that the number of blades was 12 , 14, 18 and the triangular blade model which obtains better PLTMH output. In this study, the number of blades was 14 which was the best with a resulting voltage of 9.4 volts, a current of 0.96 amperes and a power of 9.02 watts.

Abstract

Abstract. Geothermal power plants rely heavily on the efficiency of their cooling systems to optimize overall energy conversion. This study investigates the performance of the primary cooling systems, namely direct contact condensers and mechanically induced flow cooling towers in Unit 3 of PT. Pertamina Geothermal Energy Tbk, Ulubelu Area, Lampung. Performance metrics are assessed using parameters such as range, approach, and effectiveness for the cooling tower, and thermal efficiency calculations for the condenser and steam turbine. Daily operational data were collected and analyzed. The results show that fluctuations in cooling tower effectiveness significantly affect condenser vacuum and turbine efficiency. The average actual cooling tower effectiveness is 70.06%, lower than the design effectiveness of 78%. The condenser shows an average thermal efficiency of 93.80%, with effectiveness variations between 83.23% to 86.44%. The turbine efficiency based on design is 87.51%, while the actual efficiency drops to the range of 81.84% to 82.48%. This decrease indicates a performance degradation of approximately 0.94% per year. This finding underlines the important role of cooling system optimization in improving the performance of geothermal power plants.

Abstract

Pemantauan ketinggian air sangat penting untuk mencegah kerugian dan korban jiwa akibat banjir. Pengembangan sistem real-time untuk pengambilan keputusan sangat diperlukan dalam konteks ini. Penelitian ini menggunakan metode fuzzy sugeno pada prototipe pendeteksi banjir, dengan ESP 32 sebagai mikrokontroler yang dilengkapi logika fuzzy dan sensor ultrasonik A02YYUW untuk mengukur ketinggian air. Metode ini melibatkan proses fuzzifikasi, inferensi, dan defuzzifikasi. Pengujian menunjukkan sensor ultrasonik A02YYUW memiliki rata-rata eror sebesar 0,1% dan waktu respon pengambilan keputusan fuzzy sekitar 0,115 detik. Simulasi menggunakan matlab menghasilkan rata-rata eror 0%. Dengan demikian, pendeteksi banjir ini menggunakan sensor ultrasonik A02YYUW dan metode fuzzy sugeno dapat menjadi solusi efektif untuk memantau dan menginformasikan kondisi ketinggian air guna mengurangi resiko banjir.

Abstract

The main problem faced by the partner, SMA Negeri 10 Bandar Lampung, was the absence of a technology-based security system and the low level of technological literacy among students. To address these issues, a community service program was conducted through training and implementation of an embedded system focused on designing and applying a microcontroller-based doorlock security device. The activity employed several stages, including observation, interactive training, hands-on practice, and evaluation. The program was carried out over three months with five visits, involving 30 participants consisting of teachers and students. The results showed a significant improvement in participants’ knowledge, with an average increase of 51.26%, and an active participation rate reaching 95%. Furthermore, the developed security device functioned properly and was successfully implemented in one of the school’s rooms. This activity not only enhanced school security but also fostered awareness of the importance of technology utilization in education, supporting the development of digital literacy and 21st-century skills among the participants.
