Abstract

Used oil waste increases every year, engine maintenance waste will increase. Waste oil is classified as B3 waste which requires special treatment. In the development of cities and regions, the amount of fuel used continues to increase due to the increasing number of vehicles and car engines. Even in rural areas, you can find small companies, one of which uses oil. In other words, the distribution of palm oil waste is very wide, ranging from big cities to rural areas in Indonesia. The research process was to convert used oil into constant-temperature heating oil by using a distillation process. The method used aims to find out the best results at temperatures and variations of the zeolite catalyst. 350oC produces 1005 ml of fuel in 90 minutes. While the lowest results were obtained without using a zeolite catalyst to produce 105 ml of fuel. Thus, the use of zeolite is easy and effective in weakening the bonds of the hydrocarbon chains in the oil.

Abstract

Hydrogen energy is one of the alternative energies that will help overcome the scarcity of fossil energy. One of the steps to produce hydrogen energy is by the electrolysis method. In this study, the electrolysis process was carried out with a combination of peat water and coconut water. Given that in the South Kalimantan area the existence of peat land is very extensive and there are also many coconut trees. So the main raw materials used can be renewed. In addition, the composition contained in peat water can also help in the electrolysis process which consists of metal minerals such as Na, Mg, Al, Fe, Ca, K, and others. These mineral compounds will also help in accelerating the formation of hydrogen gas. The mineral compounds contained in coconut water and peat indirectly produce electrolyte properties and can be used as catalysts to accelerate the reaction to produce hydrogen gas by the electrolysis method. From the results of the research conducted, as much as 155 ml of hydrogen was produced. Hydrogen gas production, 0.6 A of electric current, and 7.3 Watts of electric power in the 30-minute electrolysis process were found in sample F (1.5 L of pure coconut water). In the electrolysis process, peat water and coconut water, the voltage used during the electrolysis process was 12 V which flowed through the cathode and anode.

Abstract

Starch based biofoams have emerged as a sustainable alternative to conventional plastics, yet their performance varies significantly depending on formulation and processing methods. This study aims to comprehensively evaluate the relationship between raw material composition, production techniques, and functional properties of biofoams through an integrated analysis of ten recent formulations. The methodology involved a systematic review of experimental data derived from diverse production methods, including thermopressing, microbial fermentation, evaporative drying, freeze drying, and molding. Results reveal that banana peel and cassava starch and banana stem fiber biofoam offers an optimal balance of high tensile strength 43.86 MPa, low water absorption 16.91%, and moderate biodegradability 65.82%, making it ideal for dry food packaging. In contrast, bamboo powder biofoam exhibits exceptional water absorption 97.1%, suitable for horticultural substrates, while bamboo cellulose–starch composite demonstrates outstanding compressive strength 78.74 MPa and thermal stability 410.86 °C, indicating potential for lightweight structural applications. These findings underscore that biofoam design must be application-specific, providing evidence-based guidance for developing effective, sustainable materials tailored to real world needs.
