The thresher machine plays an important role in palm oil processing as it functions to separate palm fruits from their bunches. This study designs a small-capacity thresher machine to make it accessible for farmers and community groups. The design process involves creating components such as the drum thresher, shaft, chassis, and wheels to ensure the machine is mobile. These components are then…
Hydrogen Hydrogen-Oxygen (HHO) gas is a renewable energy source that is gaining attention as a potential substitute for fossil fuels. HHO can be derived from water (H₂O) through a process called electrolysis using a dry cell HHO generator. This study aims to investigate the impact of adding HHO gas to Pertamax fuel with current variations of 2A, 3A, and 4A on exhaust emissions. The testing in…
Untuk menentukan cadangan hidrokarbon suatu reservoir dapat dilakukan dengan metode kurva penurunan produksi (decline curve). Berdasarkan hasil evaluasinya, maka metode kurva penurunan produksi hanya menggunakan data laju produksi, data kumulatif produksi dan waktu produksi. Metode kurva penurunan produksi ini digunakan untuk menentukan Ultimale Recovery, Remaining Reserves, dan Remaining Life.…

Isolate the essential oils of sweet orange peel, ylang ylang flowers, and clove leaves using steam distillation. The yield of each essential oil obtained in this research was sweet orange peel oil which was 0,25%, ylang ylang flower oil was 0…
Crude coconut oil was produced from copra extraction. Purifying crude coconut oil was important to eliminate unwanted taste and aroma. The purification process included degumming, neutralization, bleaching, and deodorization. Before purification, crude coconut oil had characteristics that did not meet the SNI 9804:2020 standard. The purification process reduced the water content and FFA of crud…
This research uses crude coconut oil as raw material for making cooking oil. Crude coconut oil has a high free fatty acid content and water content, a cloudy brown color, and an undesirable taste and smell so it must be purified first. The oil refining process generally consists of four main stages, namely degumming, neutralization, bleaching and deodorization. Citric acid is used to assist in …
The purposes of this study were to determine the effect of citric acid concentration on the content of water content, free fatty acids, and to determine the fatty acid content in the refining of crude coconut oil into coconut cooking oil. Water content and free fatty acids are important factors in determining the quality of cooking oil. The experimental method was employed by using variations i…
Staphylococcus aureus bacterial infection is a health threat. Treatment of infections using antibiotics has been widely used. However, misuse of antibiotics can cause resistance. One way to overcome typically by creating common fixings as antibacterials. BSF larvae oil (MLB) and tuna fish oil (MIT) are known to have antibacterial potential. This study aims to determine the antibacterial activit…
