Abstract

Micro-hydro power plants take advantage of the energy potential of low-head airflow. with the development of technology that can support it, namely the Archimedes screw turbine as the driving force. Various parameters must be considered to determine the performance of micro hydro power plants with Archimedes screw turbines. A design is carried out with a discharge parameter flow rate of 2 l/s, a turbine slope of 300, and an immersion level variation of 0.3, 0.5, and 0.7, where the final result shows the value of torque, hydraulic power, mechanical power, generator, and efficiency, which decreases with the level of water immersion in the last blade.

Abstract

Microbial fuel cell (MFC) is a technology that utilizes the biological activity of microorganisms to produce electricity from organic energy in the form of waste. Waste that is often encountered in everyday life, some of which are rice washing water and banana peel waste, which are easy to find and are often thrown away without being used, even though they contain organic content, which is a food source for microbes, which can later be converted into metabolic products from these microbes to produce electricity. Electricity within the microbial fuel cell (MFC) system. The microbial fuel cell in this research used a variety of substrates of rice washing water, banana peels and a mixed substrate of rice washing water and banana peels, as well as variations in incubation times of 3, 5 and 7 days. From the research that has been carried out, it is known that variations in the substrate mixture of rice washing water and banana peels (50%; 50%) have the greatest electric current, namely 0.262 mA at an incubation time of 5 days. In all substrate variations, there was an increase in electric current on the 3rd and 5th days of incubation and a decrease on the 7th

Abstract

Gelam wood is a natural species in swamp forests and is found in many peat swamp forests in South Kalimantan. Due to the abundant availability of gelam wood raw materials in this region and the need for biomass-based energy, wood pellets from gelam wood can be a solution. In this research, an evaluation was carried out on the quality of gelam wood pellets which included calorific value, specific gravity, and pressure test. In addition, an economic analysis of kayu gelam pellets was also carried out. This study used adhesives in the form of tapioca and wheat flour, variations in adhesive percentages of 0%, 5%, 10%, 15%, and powder sizes of 40 mesh, 50 mesh, and 60 mesh. The results of the research show that the calorific value decreases as the size of the gelam sawdust decreases and tapioca adhesive provides the best calorific value. Larger mesh sizes tend to produce higher compression test values and denser specific gravity. From an economic perspective, gelam wood pellets are relatively cheaper and easier to obtain
