Abstract

Bahan baku biomassa yang dapat dimanfaatkan salah satunya adalah Kulit Kacang Tanah dengan Perekat Biji Nangka, kulit kacang tanah dan biji nangka yang melimpah di sekitar masyarakat dan kurang dimanfaatkan. Tujuan dari penelitian ini adalah untuk mengetahui komposisi variasi perbandingan perekat terbaik briket dari kulit kacang tanah menggunakan perekat biji nangka dan membuat karakteristik briket terbaik. Metode penelitian yang digunakan adalah metode eksperimen dan karakteristik fisik briket. Hasil penelitian menemukan bahwa briket kulit kacang tanah menggunakan perekat biji nangka mendekati SNI dan tidak mendekati standar mutu komersial dan baku mutu briket inggris. Dimana pada komposisi ini memiliki nilai kalor sebesar 4.342,19 kal/g, kadar air 4,12%, dan kadar abu sebesar 3,8%. Hal ini menunjukkan bahwa bahan baku kulit kacang tanah melalui metode karbonisasi dapat digunakan sebagai bahan baku dalam pembuatan briket dan perekat biji nangka digunakan sebagai bahan perekat dengan pertimbangan pencampuran perekat atau variasi penggunaan perekat.

Abstract

World energy demand continues to increase by 45% until 2030 based on projections of the International Energy Agency (IEA) with an average increase of 1.6% per year. About 80% of these energy needs supplied by fossil fuels. This increase occurred due to population growth, industrialization, lifestyle changes, and the use of increasingly complex technology. The household sector is one of the sectors that require energy to meet daily needs. Researchers conducted a study of research results related to rooftop Solar Power Plants, the use of thermoelectric as a producer of electrical energy, and the use of septic tanks for household gas with digesters that have been published in Indonesian-language journals and proceedings. The concept of a smart home base is implemented assuming a simple housing design, in this design than a technical calculation of the feasibility of a Smart Home Base is carried out which considers efficient methods in the development and provision of energy independently based on renewable energy for cost savings and supports government programs abaout Indonesia Ketahanan Energi 2030. Renewable energy applied to the smart home base concept utilizes Solar Power Plants which are hybrid with Thermoelectric Generators and biogas to replace of the LPG stove. Utilization of IoT-based technology to optimize energy savings at home. The housing concept is assumed with a simple housing design with a daily energy consumption of 5,507 Wh and 1,336 watts of power. The solar system used is 450 Wp for as many as 8 units of solar panels, 12 v 200 Ah battery capacity of as many as 8 units of batteries, and inverters with a power of 2000 Watts.

Abstract

Indonesia as one of the largest producing and exporting countries of crude palm oil (CPO). However, Indonesia still has not utilized the potential of the waste that generated by using CPO as cooking oil, namely used cooking oil. The high content of free fatty acids (FFA) in used cooking oil will cause the saponification reaction and interfere the processing into biodiesel. Cocoa bean shell charcoal (Theobroma cacao L) has a K2CO3 content similar to its commercial product, and contains some traces of silicates and sulfates so that it can increase the efficiency of reducing free fatty acids. In this study, tests were carried out to reduce FFA levels in used cooking oil using charcoal from cocoa bean husks activated with HCl, varying the concentrations of 6, 8 and 10 Molar, as well as the temperature treatment during the process of mixing used cooking oil with activated charcoal adsorbent, which was 75 , 100, and 150°C. The best FFA reduction results were found in the A3T2 reactor which reached 80%, where the best HCl concentration was 10 Molar and the temperature of the mixing process with the adsorbent was 100°C and produced a biodiesel yield of 75%. The quality of the biodiesel produced complies with SNI 7182-2015 standards, 867 kg/m3 of density, 0.5 mg KOH/g of acid number, 1.52 cSt of kinematic viscosity, 48.081 MJ/kg of calorivic value and 143.99%- mass of methyl ester content.

Abstract

The research presents a comprehensive exploration of energy calculations and pond design for smart cultivation systems, with a focus on shrimp ponds. Through interviews and analysis, the energy consumption of various components such as lights, waterwheels, and pumps was determined, leading to the calculation of total power consumption and the specification of necessary equipment like inverters, batteries, and solar panels. Furthermore, the study proposes the integration of renewable energy sources, such as solar and wind power, into the pond system, enhancing sustainability and reducing environmental impact. The incorporation of IoT technology facilitates real-time energy monitoring and optimization. Additionally, innovative solutions like water filtration systems and solar-powered automatic feeders are introduced to improve water quality and feeding efficiency, respectively. The application of microcontroller-based solar street lighting enhances energy efficiency and maintenance ease. A SWOT analysis underscores the strengths, weaknesses, opportunities, and threats of the proposed smart cultivation system, emphasizing its potential for energy efficiency, environmental friendliness, and long-term cost savings despite challenges such as weather dependence and technological limitations. Overall, the research underscores the feasibility and benefits of integrating renewable energy and modern technology in shrimp pond management for sustainable and efficient aquaculture practices.
