Abstract

Meskipun biodiesel merupakan bahan bakar alternatif yang memiliki potensi yang menjanjikan untuk digunakan pada mesin diesel. Namun nyatanya saat ini, biodiesel yang digunakan dipasaran masih dominan kandungan solar dari bahan bakar fosil dan biodiesel dijadikan sebagai bahan tambahan. Tujuan penelitian ini untuk menurunkan angka kadar emisi gas buang yang dihasilkan oleh biodiesel (B20). Penelitian ini dilakukan dengan metode eksperimen, beberapa sampel diuji terdiri dari bahan bakar biodiesel (B20), kemudian biodiesel ini ditambahkan dietil eter (DEE) dengan rasio 1%, 2%, 3%, 4% dan 5% pada tiap liternya. Pengujian beberapa sampel ini dilakukan untuk mengetahui kadar emisi gas buang (opasitas) yag dihasilkan tiap sampel menggunakan alat Smokemeter Opacity. Hasil penelitian dari penambahan dietil eter (DEE) ke dalam biodiesel (B20) mampu menurunkan kadar opasitas. Kadar opasitas terendah didapatkan pada campuran dietil eter (DEE) sebesar 5% yaitu 42,37%. Dimana nilai perbedaan atau penurunan ketebalan asap atau opasitas jika dibandingkan dengan biodiesel (B20) yaitu 2,88% untuk B20 + 1% DEE, 4,26% untuk B20 + 2% DEE, 7,70% untuk B20 + 3% DEE, 10,50% untuk B20 + 4% DEE dan 12,76% untuk B20 + 5% DEE. Kata Kunci: Dietil Eter, Biodiesel (B20), Emisi Gas Buang, Opasitas

Abstract

The increasing demand for skilled human resources in the field of automation by the workforce has encouraged vocational education institutions to align their graduates' competencies with industry needs. Students must be equipped with up-to-date skills in line with technological advancements. Currently, the availability of technical expertise programs in vocational high schools (SMK) that include industrial automation curricula is very limited. This situation does not align with the growing industrial demand for SMK graduates with automation competencies, such as wiring and PLC programming skills. Based on these circumstances, this automation system training based on PLC was conducted as part of a community service program. The activity aimed to enhance the skillsets of vocational high school students, particularly in the machining engineering department. The training utilized PLC-based automation systems with Omron CP1E E30-DR-A controllers. The PLC logic programming was performed using CX-Programmer software. The results of the program showed that most participants could grasp the material well. Moreover, all participants gained new insights and skills in industrial automation systems, which serve as valuable support when entering the workforce.

Abstract

Bus is a very important transportation for all people in the world. The majority of a bus that operates still uses non-renewable fuel. The conventional bus produces exhaust emissions that can damage the environment. Current research is about changing the conventional internal combustion engine bus into an electric bus, therefore it is necessary to test the strength of the frame structure to determine its strength after changing with the electric system. The objective of this current study is to analyze the bending strength and optimization of a medium electric bus frame structure using the Finite Element Method in static conditions. Optimization will be conducted after obtaining results of bending analysis to determine the minimum weight of the bus frame structure without violating bending strength. The results of the bending analysis are stress and displacement which will be used as a constraint in the optimization process. The optimization that will be used is size optimization. The design variable is the thickness of each bus frame structure. Results show that the weight of the structure is reduced by 12% without compromising on strength and safety requirements.

Abstract

This study aims to determine the effect of the addition of montmorillonite bentonite powder on the mechanical properties and burn resistance of phenolic resin-based composites. Composite samples were made with variations in bentonite weight fractions of 0%, 5%, 10%, and 15%. The impact test was carried out using the Izod method to determine the energy absorption and impact price, while the burn resistance was tested based on the ASTM D635 standard to determine the Time of Burning (TOB) and the Rate of Burning (ROB). The test results showed that the addition of bentonite lowered the impact price, with the highest value of 0.0082 J/mm² in the 0% fraction and the lowest of 0.0008 J/mm² in the 5% fraction. The highest absorption energy is obtained in the 10% fraction of 0.145 J. This decrease in mechanical performance is influenced by the inhomogeneous distribution of the catalyst and the presence of voids in the composite structure. In contrast, the addition of bentonite provides a significant increase in burn resistance. Composites with a fraction of 15% show the highest TOB of 20 seconds and the lowest ROB of 9.4 mm/min, indicating increased flame resistance. The mineral content of montmorillonite in bentonites, such as silica and alumina, contributes to slowing down the rate of combustion through increased material density and stable thermal properties. The results of this study show that montmorillonite bentonite powder has the potential to be used as a flame retardant additive in composite materials, but it needs to be studied further to maintain a balance between fire resistance and mechanical strength.

Abstract

The use of Honda Beat motorcycles in 2016 is still quite dominant among two-wheeled vehicle users. One of the efforts to improve vehicle performance is done by replacing standard spark plugs with racing spark plugs, installing groundstraps on coil cables, and modifying the ECU remap using the Juken 5 ECU with a limiter increased to 10,000 RPM. Groundstraps play a role in stabilizing the flow of electric current in the vehicle's electrical system, so that it can increase ignition efficiency and produce stronger and more consistent sparks on the spark plugs. The purpose of this study was to determine the effect on the performance of Honda Beat FI motorcycles that use racing spark plugs, groundstraps on coil cables and ECU remaps. This study needs to be done, so that motorcycle users can improve vehicle performance by adding groundstraps to the high-voltage coil cables. This study uses an experimental method. Dynotest is used to determine the resulting performance. The first step taken, testing, tuning and continued testing. The results showed that standard conditions produce a torque of 6.97 N.m and a power of 6.3 HP; The condition without a groundstrap produces 6.98 N.m of torque and 6.9 HP of power; while the condition with a groundstrap produces 6.99 N.m of torque and 6.4 HP of power. The torque generated by testing using a groundstrap increased compared to standard conditions, and power output also increased. Therefore, the use of a groundstrap and ECU remap affects the motorcycle's torque and power performance. Torque is essential for acceleration and climbing, while power influences top speed.

Abstract

Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keterampilan dan kapasitas peternak sapi di Kecamatan Musuk, Boyolali, melalui penerapan teknologi pencacah hijauan dan teknik fermentasi silase. Program dilaksanakan dengan pendekatan partisipatif yang melibatkan 15 peternak anggota Slamet Jaya Farm selama delapan bulan. Kegiatan meliputi perancangan dan pembuatan mesin pencacah sederhana, pelatihan teknis, demonstrasi praktik pembuatan silase, serta pendampingan berkelanjutan. Mesin pencacah yang dirancang menggunakan motor 1 HP dengan kapasitas 200 kg/jam terbukti mampu menurunkan waktu pengolahan dan menghasilkan ukuran cacahan hijauan seragam 2–5 cm. Hasil program menunjukkan bahwa 82% peserta berhasil mengoperasikan mesin dan memproduksi silase berkualitas dengan pH optimal 3,8–4,2, sedangkan 71% mulai memanfaatkan limbah pertanian sebagai bahan baku silase. Program ini membuktikan bahwa teknologi tepat guna yang dikombinasikan dengan pelatihan intensif mampu meningkatkan pengelolaan pakan dan mendukung keberlanjutan usaha peternakan sapi lokal.
