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

Abstract

South Kalimantan is one of the natural habitats of gelam wood. In South Kalimantan, gelam wood can grow well and fertile. This makes the availability of gelam wood abundant and can be used for various purposes, one of which can be used as raw material for wood pellets (biomass energy). Wood pellets made from gelam wood have not been widely studied, so it is necessary to know the effect of the size of gelam wood powder and the addition of the percentage of adhesive on the physical properties of gelam wood pellets. Wood pellets made from gelam were made using various sizes of powder (mesh) 40, 50, and 60 as well as using flour adhesive (percentage of adhesive 5%, 10%, and 15%). Gelam wood pellets were then tested for physical properties in order to determine their performance. From the research that has been carried out, it is found that the volatile matter content, ash content, and water content tend to increase with the smaller size of the gelam sawdust. Meanwhile, the calorific value and fixed carbon content have a tendency to decrease with the smaller size of the gelam sawdust. volatile matter content, ash content, and water content tend to increase as the percentage of adhesive is increased. Meanwhile, the calorific value and fixed carbon content tend to decrease with the increase in the percentage of the amount of adhesive.

Abstract

A composite is a material formed from the combination of two or more constituent materials through an inhomogeneous mixture. The ironwood waste has less economic value, which makes the authors interested in conducting research using mosquito nets and particle composite ironwood waste. Which is to find out the effect of volume fraction and angle orientation of the fiber composite polyester-ulinwood powder (Eusideroxylon zwageri)-mosquito wire on the bending strength. The bending test was carried out using the ASTM D-790 standard with the three point bending test method and the composite was manufactured using the hand lay-up method with the particle composition: polyester: 10%: 90%, 15%: 85%, 20%: 80%, and 25%: 75%. The results obtained in the comparison of the composition of less ironwood powder, a finer mesh size with an orientation angle of 45°, and mosquito wire show the highest bending strength and high deformation ability (ductile), and the addition of mosquito net as one of the composite specimen fibers of polyester resin does not increase significant bending strength but can reduce the deformability reduction effect.

Abstract

Kebutuhan masyarakat akan energi listrik terus meningkat setiap tahun. Di masa depan, kebutuhan listrik akan semakin bertambah seiring dengan pertumbuhan populasi, investasi, dan kemajuan teknologi, termasuk perkembangan di sektor pendidikan di semua jenjang. Untuk memenuhi permintaan listrik yang terus meningkat, pemerintah terus berupaya mengembangkan teknologi dan membangun pembangkit listrik. Salah satu teknologi pembangkit listrik adalah microbial fuel cell. Microbial fuel cell adalah sistem bio-elektrokimia yang memanfaatkan metabolisme alami mikroba untuk menghasilkan listrik. Dalam penelitian ini, microbial fuel cell menggunakan berbagai substrat, termasuk air cucian beras, kulit pisang kepok, serta campuran keduanya, dengan masa inkubasi 3, 5, dan 7 hari. Penelitian menunjukkan bahwa campuran kulit pisang kepok dan air cucian beras menghasilkan rata-rata 67.086 mW daya listrik, yang lebih tinggi dibandingkan substrat air cucian beras atau kulit pisang kepok secara terpisah.
