Abstract

The exploration of natural resources as materials for engineering applications is increasingly important, as organic materials offer greater environmental benefits. The Maja fruit, a typical Indonesian plant, has not been fully utilized for engineering purposes, particularly its shells. The goal of utilizing this material is to contribute to sustainable development. In this study, Maja fruit particles were used as a filler in combination with rice husk ash. The particle compositions of Maja fruit were set at 20%, 30%, and 40%, respectively. The composite fabrication process was conducted under cold conditions at a pressure of 30 MPa. The results indicated that an increase in the composition of Maja fruit shell particles led to higher compressive strength in the composite, although this caused a decrease in surface hardness. The optimal composite performance was achieved with a composition of 40% Maja fruit shell particles and 60% epoxy resin, as determined by a weighting method. It was also observed that while the inclusion of rice husk ash tended to reduce compressive strength, it contributed to enhancing the hardness of the composite.

Abstract

The technology aimed at reducing dependence on fossil fuels and minimizing exhaust emissions involves the use of ethanol as an alternative fuel. This research investigates the effects of blending ethanol with RON 92 (Pertamax) gasoline on the exhaust emissions of a 2000cc four-cylinder gasoline engine. Experiments were conducted using varying ethanol concentrations, and the emissions of carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO₂), and oxygen (O₂) were measured and analyzed. Data were presented descriptively and compared. The results indicate that adding ethanol significantly reduces CO and HC emissions. The lowest CO concentration (0.04%) was recorded with a 10% ethanol blend (BE10%), while the lowest HC emission (2316 ppm) occurred at a 15% ethanol blend (BE15%). Conversely, CO₂ emissions increased with ethanol content, peaking at 8.97% for BE15%. These findings demonstrate the potential of ethanol–gasoline blends to lower harmful emissions, particularly CO and HC, while enhancing combustion efficiency, as reflected by the increase in CO₂ levels.

Abstract

IPST Asari, di bawah naungan PT Chandra Asri Petrochemical, mengelola sampah plastik menjadi solar plastik melalui proses pirolisis. Penelitian ini bertujuan untuk mengevaluasi kinerja mesin diesel satu silinder menggunakan bahan bakar solar plastik yang diproduksi oleh IPST Asari. Mesin diuji pada putaran 1200 RPM, 1600 RPM, dan 2000 RPM dengan pembebanan tetap 1000 Watt. Bahan bakar yang diuji meliputi solar plastik murni dan campuran solar plastik dengan dexlite dalam rasio D100, PO30, PO50, PO70, dan PO100. Hasil penelitian menunjukkan bahwa kinerja mesin dengan PO100 lebih rendah dibandingkan dengan dexlite; secara spesifik, pada 1200 RPM, daya efektif lebih rendah 16,73%, torsi lebih rendah 17,34%, dan efisiensi termal hanya mencapai 10,59%. Selain itu, konsumsi bahan bakar spesifik (SFC) dari solar plastik 33,81% lebih tinggi dibandingkan dexlite. Meskipun demikian, solar plastik tetap menjadi bahan bakar alternatif yang layak, menghadirkan solusi berkelanjutan untuk pemanfaatan energi dari sampah. Penelitian ini menyimpulkan bahwa meskipun solar plastik menghasilkan metrik kinerja yang lebih rendah dibandingkan dexlite konvensional, ia menawarkan jalur yang menjanjikan untuk konversi sampah menjadi energi, menyoroti potensi manfaat lingkungan dan ekonomi yang lebih luas.
