Abstract

Penelitian ini bertujuan untuk menginvestigasi pengaruh konsentrasi asam sitrat terhadap penurunan bilangan asam pada biosolar. Dalam eksperimen ini, variasi konsentrasi asam sitrat diterapkan pada biosolar, dan kemudian dilakukan pengukuran terhadap bilangan asamnya. Metode eksperimental yang digunakan memperhitungkan faktor-faktor yang mungkin memengaruhi hasil, seperti suhu dan waktu reaksi. Hasil penelitian menunjukkan bahwa terdapat korelasi antara konsentrasi asam sitrat dan penurunan bilangan asam pada biosolar. Dengan kata lain, konsentrasi asam sitrat yang tepat mampu menurunkan bilangan asam dalam biosolar. Temuan ini memiliki implikasi penting dalam pengembangan teknologi pengolahan bahan bakar, terutama dalam meningkatkan kualitas biosolar sebagai alternatif yang lebih ramah lingkungan. Dengan memahami faktor-faktor yang memengaruhi penurunan bilangan asam, dapat dirancang strategi yang lebih efektif untuk meningkatkan efisiensi proses pengolahan biosolar di masa depan. Kesimpulannya, penelitian ini memberikan kontribusi berharga dalam konteks peningkatan kualitas dan kinerja biosolar sebagai bahan bakar alternatif, selain itu penurunan bilangan asam juga dapat meningkatkan efisiensi mesin pada kendaraan, pembakaran yang lebih bersih dan pengurangan keausan pada komponen mesin.

Abstract

Indonesia, as a country rich in natural resources, has a very diverse mining sector, including oil and gas mining. In an effort to increase national oil production and improve the standard of living and welfare of the community, regulations are needed to regulate the management and business of oil. Regulation of the Minister of Energy and Mineral Resources No. 01 of 2008 concerning Guidelines for the Business of Oil Mining in Old Wells. This regulation is considered an implementation of the principles contained in Article 33 of the 1945 Constitution and provides positive support for Regional Governments that have many old wells. The regulation opens up opportunities for increasing Regional Original Income (PAD) and community welfare through the participation of Village Unit Cooperatives (KUD) or Regionally-Owned Enterprises (BUMD) in oil production in old wells in their areas. In addition, in the distribution of oil, this mode of transportation is also an important aspect for Village Unit Cooperatives (KUD) or Regionally-Owned Enterprises (BUMD) in the Bojonegoro Regency area, which, as one of the regencies in East Java Province, is an area that produces oil and gas that is still active to this day. Oil fields in Kedewan District, Bojonegoro Regency, are generally old fields that have been made since the Dutch era, so their production has decreased. Even so, the potential of old oil wells that have been closed can still be managed and utilized through traditional mining methods by involving local communities both in management and in the distribution of oil by land transportation from oil wells to storage areas in the work area of PT Pertamina EP Asset 4 Cepu Field. This study aims to obtain information about problems in the distribution of oil transportation from old wells to storage/reservoirs related to policies, regulations, infrastructure conditions, and their dynamics. The research methods that will be used involve observation, documentation, inventory, and interviews, with qualitative methods and thematic analysis. The results of this study are expected to produce outputs in the form of scientific articles or national journals.
