Abstract

Untuk memastikan efisiensi yang optimal dari tenaga yang dihasilkan melalui pembakaran, diperlukan sistem pelumasan yang tepat. Secara umum, fungsi utama pelumas ialah sebagai perantara mengurangi gesekan dan keausan. Sistem pelumasan pada mesin kendaraan penting, karena kualitas sistem pelumasan mempengaruhi kinerja dan umur mesin. Penelitian ini bertujuan untuk menganalisis pengaruh variasi jenis base oil terhadap suhu mesin dan konsumsi bahan bakar pada mesin mobil hemat energi. Penelitian dilakukan dengan menggunakan tiga jenis base oil yaitu oli mineral grup 2, oli semi sintetik, dan oli full sintetik dengan viskositas SAE 10W-30. Pengujian dilakukan pada mesin bensin 4 tak berkapasitas 100cc dengan bahan bakar pertamax. Pengukuran dilakukan pada putaran idle ±1500 rpm selama 10 menit. Hasil penelitian menunjukkan bahwa jenis base oil berpengaruh terhadap suhu mesin dan konsumsi bahan bakar. Oli full sintetik memberikan performa terbaik dengan suhu mesin yang lebih rendah dan konsumsi bahan bakar yang lebih efisien dibandingkan dengan oli mineral grup 2 dan oli semi sintetik. To ensure optimal efficiency from the power generated through combustion, an appropriate lubrication system is necessary. In general, the main function of lubricants is to act as intermediaries in reducing friction and wear.  The lubrication system in vehicle engines is crucial as its quality affects the performance and lifespan of the engine. This study aims to analyze the influence of variations in base oil types on engine temperature and fuel consumption in energy-efficient car engines. The research was conducted using three types of base oils: Group 2 mineral oil, semi-synthetic oil, and full synthetic oil, all with a viscosity of SAE 10W-30. Testing was performed on a 100cc 4-stroke gasoline engine using pertamax fuel. Measurements were taken at an idle speed of approximately 1500 rpm for 10 minutes. The results showed that the type of base oil significantly affects engine temperature and fuel consumption. Full synthetic oil provided the best performance with lower engine temperatures and more efficient fuel consumption compared to Group 2 mineral oil and semi-synthetic oil.

Abstract

Sepeda motor merupakan alat transportasi yang digerakkan oleh mesin (motor). Jenis transportasi ini banyak digunakan karena harganya yang murah dan mudah digunakan. Sepeda motor umumnya menggunakan bahan bakar bensin. Motor bensin 4 langkah adalah motor bensin yang melakukan usaha atau kerja diperlukan 4 langkah gerakan piston dan 2 putaran poros engkol. Catalyst adalah salah satu teknologi yang digunakan untuk mereduksi gas buang CO menjadi CO2 dan HC menjadi H2O, pada saat dikeluarkan pada knalpot. Knalpot katalis B yang lebih bagus dalam mereduksi emisi gas CO disetiap rpm nya. Dan dengan menggunakan knalpot katalis C berhasil menyerap emisi gas buang HC yang signifikan pada rpm 3000 dan 5000. Penambahan katalis pada knalpot berhasil mereduksi kebisingan. Dari ketiga model variasi katalis yang divariasi, knalpot katalis B yang paling baik dalam mereduksi kebisingan. dikarena bentuk katalisnya yang dapat lebih baik menghambat aliran pembuangan pada knalpot karena itulah suara yang keluar jadi sedikit lebih senyap. A motorbike is a means of transportation that is driven by an engine (motor). This type of transportation is widely used because it is cheap and easy to use. Motorcycles generally run on gasoline. A 4-stroke gasoline engine is a gasoline engine that does work or work that takes 4 steps of piston movement and 2 rotations of the crankshaft. Catalyst is one of the technologies used to reduce CO exhaust gas to CO2 and HC to H2O when released in the exhaust. The catalyst B exhaust is better at reducing CO gas emissions at every rpm. And by using an exhaust catalyst C managed to absorb significant HC exhaust emissions at 3000 and 5000 rpm. The addition of a catalyst to the exhaust managed to reduce noise. Of the three models of varied catalyst variations, exhaust catalyst B is the best at reducing noise. because the shape of the catalyst can better inhibit the flow of exhaust in the exhaust, that's why the sound that comes out is a little quieter.

Abstract

One of the abundant biomass resources in Indonesia is water hyacinth, which can be converted into energy through pyrolysis. This research explores the effect of temperature on the co-pyrolysis process of a mixture of water hyacinth and young coal to produce bio-oil, gas, and char. The method used is pyrolysis with temperature variations on the mixture of water hyacinth and young coal in a batch reactor.  The testing was conducted at a temperature of 400°C with various compositions of water hyacinth and coal mixtures, and the resulting products in the form of bio-oil, gas, and char were then measured to determine the yield. The research results show that in the pyrolysis of pure water hyacinth, gas production reaches 120 grams, bio-oil 108 grams, and char 72 grams. The addition of coal up to 30% increases char production to 113 grams, but decreases gas production to 94 grams and bio-oil to 87 grams.  The gas produced is dominated by methane (67.315%) in a mixture of 70% water hyacinth and 30% coal, while hydrogen reaches 33.721% in pure water hyacinth.

Abstract

Backround: Despite increasing smartphone penetration in rural Indonesia, livestock micro-entrepreneurs face persistent challenges in leveraging digital technologies for business development, creating critical gaps between technology access and functional digital literacy that constrain economic opportunities.Objective: This study investigates digital literacy challenges among livestock micro-entrepreneurs in Kuningan, Indonesia, examining capability deficits, underlying barriers, and business consequences to inform targeted intervention design.Method: A rapid qualitative research design was employed over three months, conducting in-depth semi-structured interviews with 18 purposively-sampled livestock micro-entrepreneurs (poultry and cattle farmers) representing diverse demographics. Data collection integrated interviews, direct observation of smartphone usage, and literature review, analyzed through thematic analysis identifying patterns of digital literacy challenges and barrier categories.Findings and Implications: Despite universal smartphone ownership, participants exhibited profound deficits across four dimensions: operational skills (88.9% lacked file management understanding), informational literacy (88.9% never checked online prices before selling), strategic competency (100% showed no proactive customer engagement), and safety awareness (94.4% vulnerable to phishing). These gaps emerged from intersecting factors including age, education, gender opportunity structures, training absence, and infrastructural constraints.Conclusion: Business consequences included 18-27% revenue losses from intermediary dependency, preventable livestock mortality, and financial exclusion imposing higher lending costs. Digital literacy deficits impose substantial economic penalties that far exceed intervention costs. Effective inclusion requires multifaceted approaches addressing not just skills but also psychological barriers, institutional support systems, and infrastructural limitations.
