Abstract

Jatropha Curcas stands out as a promising plant-based feedstock, offering a non-edible oil that holds great potential as an alternative fuel to traditional diesel. Notably, Jatropha oil boasts favourable fuel properties, including a higher oil content compared to other alternatives. This attribute makes it an attractive candidate for biodiesel production. Importantly, as a non-edible oilseed feedstock, Jatropha Curcas helps mitigate concerns related to food prices and the ongoing food versus fuel debate, offering a sustainable solution to the growing energy demands. Furthermore, the plant exhibits impressive yields, with the potential to produce up to 40% oil weight per seed. This high yield not only enhances the economic viability of Jatropha-based biodiesel but also underscores its efficiency as a feedstock. The discussion extends beyond mere fuel properties, encompassing a comprehensive comparative review that delves into engine performance and emission characteristics associated with Jatropha Curcas. The novelty of this paper lies in its exploration of the crude oil aspects of Jatropha curcas, shedding light on an essential facet often overlooked. By presenting a thorough analysis of fuel properties, engine performance, and emission characteristics, the paper contributes valuable insights to the discourse on sustainable energy solutions. Moreover, it goes beyond technical aspects and provides perspectives on the current economic status, offering a holistic view of the potential impact of Jatropha Curcas in the broader context of renewable energy and economic development.

Abstract

Penelitian ini bertujuan untuk menyintesis, mengkarakterisasi, dan menginvestigasi performa tribologi dari pelumas campuran yang terbuat dari minyak nyamplung (Calophyllum inophyllum) dan minyak mimba (Azadirachta indica). Minyak dari kedua tanaman ini diekstraksi dan dicampurkan untuk menghasilkan pelumas yang ramah lingkungan, yang kemudian diuji melalui berbagai metode karakterisasi fisik dan kimia. Karakterisasi meliputi pengukuran viskositas, densitas, bilangan asam, titik nyala, dan indeks viskositas. Formulasi biopelumas yang dihasilkan memiliki nilai indeks viskositas sebesar 201,01, yang menunjukkan kestabilan viskositas yang sangat baik terhadap perubahan suhu. Selain itu, uji tribologi dilakukan untuk mengevaluasi koefisien gesekan, keausan, dan daya tahan pelumas dalam kondisi operasi mesin yang bervariasi. Hasil uji tribologi menunjukkan bahwa formulasi biopelumas memiliki diameter keausan sebesar 0,096 mm, yang mengindikasikan performa perlindungan aus yang sangat baik. Hasil penelitian secara keseluruhan menunjukkan bahwa campuran minyak nyamplung dan minyak mimba memiliki potensi yang baik dalam mengurangi gesekan dan keausan, serta memberikan performa yang stabil pada temperatur tinggi. Penelitian ini menunjukkan bahwa minyak mimba dan minyak nyamplung dapat menjadi alternatif pelumas yang berkelanjutan dan ramah lingkungan untuk industri, meskipun masih memerlukan modifikasi lebih lanjut untuk meningkatkan kinerjanya.
