Abstract

The number of motorized vehicles in Indonesia is increasing. Therefore, alternative fuels are needed to meet the needs. One of them is LPG (liquified petroleum gas). However, in its application, the engine temperature becomes hotter, making it less efficient, and specific fuel consumption is not optimal. The Water Injection System is one of the additional technologies that can be used to reduce engine heat. This study will compare the results of specific fuel consumption and engine wall temperature with adding a water injection system on a 100cc engine. The data collection results on specific fuel consumption at 3000 RPM without water injection showed the highest figure at 0.0410 (kg/HP.hour), with the addition of a water injection system, it produced 0.0405 (kg/HP.hour). The average engine working temperature without a water injection system was 90.3 0C while adding a water injection system showed 87.8 0C. Jumlah kendaraan bermotor di Indonesia semakin meningkat. Untuk itu diperlukan bahan bakar alternatif untuk memenuhi kebutuhan. Salah satunya adalah LPG (liquified petroleum gas). Namun pada aplikasinya, temperatur mesin menjadi lebih panas, sehingga kurang efisien dan konsumsi bahan bakar spesifiknya tidak optimal. Water injection System adalah salah satu teknologi tambahan yang dapat digunakan untuk mengurangi panas mesin. Penelitian ini akan membandingkan hasil specific fuel consumption dan temperatur dinding mesin dengan penambahan water injectiontion system pada mesin 100cc. Hasil pengambilan data specific fuel consumption pada 3000 RPM tanpa water injection menunjukkan angka tertinggi di 0,0410 (kg/HP.jam) dan dengan penambahan water injection system menghasilkan 0,0405 (kg/HP.jam). Temperatur kerja mesin rata rata tanpa water injection system menunjukkan 90,3 0C sedangkan ketika menambahkan water injection system menunjukkan 87,8 0C.

Abstract

The rapid development of Internet of Things (IoT) technology and smart sensors in the automotive industry opens up great opportunities in the world of education, especially at the high school level. This community service program aims to introduce Arduino-based sensor and microcontroller technology to students of SMAN Ambulu Jember through a workshop approach and project-based learning. The method used in this activity uses the PAR (participatory action research) method with an interactive workshop approach and project-based learning that includes an introduction to types of automotive sensors such as DHT11, HC-SR04, and LDR as well as sensor installation and programming practices. The evaluation results showed a significant increase in students' understanding of the concept of IoT and microcontrollers, as well as a high interest in studying the field. This workshop proves the effectiveness of the interactive learning model in improving students' technological literacy and readiness to face the challenges of industry 4.0.

Abstract

Indonesia observes a yearly rise in motor vehicle possession. Failure to consider alternate fuels in these trends may result in the depletion of gasoline. Out of the potential alternatives, Liquified Petroleum Gas (LPG) appears to be the most favorable. The sole issue lies in the elevated engine temperature and subsequent decrease in performance caused by its utilization. To address this vulnerability, it is advisable to employ a cooling injection method, such as water injection. Nevertheless, the rise in exhaust emissions linked to water injection highlights the necessity for optimization. This study aims to optimize coolant injection systems by conducting experiments with different modifications, such as conventional intake surfaces, dimple intake surfaces with gaps, and dimple intake surfaces without gaps. The gapless dimple inlet surface demonstrates superior performance in terms of exhaust emissions, power, and torque compared to both conventional inlet surfaces and slotted dimple inlet surfaces

Abstract

This study presents the optimization of burner design and experimental evaluation using liquid fuel derived from polypropylene (PP) waste pyrolysis to achieve high thermal efficiency. The increasing accumulation of plastic waste and rising energy demand have driven the development of alternative fuels and more efficient combustion systems. In this work, polypropylene waste was converted into liquid fuel through a pyrolysis process and subsequently utilized as the primary fuel in a modified burner system. The optimization focused on key design parameters, including nozzle diameter, air–fuel mixing configuration, and combustion chamber geometry to enhance atomization quality, flame stability, and heat transfer performance.Experimental tests were conducted under various operating conditions to evaluate combustion characteristics, fuel consumption rate, flame temperature, and thermal efficiency. The results show that the optimized burner configuration produced a stable blue–orange flame with improved atomization and more complete combustion compared to the initial design. The maximum thermal efficiency achieved was 105.54%, indicating a significant improvement due to better air–fuel mixing and reduced heat losses during the combustion process. Furthermore, the pyrolysis oil demonstrated strong potential as an alternative liquid fuel for small-scale thermal applications.This study provides a practical contribution to waste-to-energy technology by integrating burner design optimization with plastic waste-derived fuel utilization, offering an effective approach to enhance thermal system performance while supporting sustainable and scalable small-scale energy solutions.
