Adsorption is the process of fluid molecules contacting the surface of a solid material. This study aims to remove carbon dioxide (CO2) gas in biogas using natural zeolite-based adsorbent pellets by adsorption and desorption of CO2 from the adsorbent using air. CO2 removal was carried out to determine the percentage of CO2 removal efficiency with variations in biogas flow rates (100 mL/minute, 300 mL/minute, and 500 mL/minute) and variations in the type of adsorbent pellets (particle size, activation time, calcination time, and dealumination activation treatment). Determination of the percentage of CO2 removal is carried out by flowing the biogas into the column and contacting it with the adsorbent continuously for 30 minutes and the output gas is collected in a gas collector to analyze the remaining CO2 content. The results showed that the best CO2 removal was 97.7% using an adsorbent with a particle size of 140 mesh, 4 hours of calcination, 90 minutes of activation time, and dealumination activation at a flow rate of 100 mL/minute. The breakthrough characteristic curve presents the characteristic â€œSâ€ profile at constant flow rate (100 mL/minute).

Black soldier fly larvae shells/BSF-based chitosan can be utilized as polymer electrolyte membrane. This research aims to analyze the physical characteristics of BSF chitosan/PVA/PAN/NH4Cl by varying amount of chitosan and ratio of PVA: PAN. Membrane was fabricated using the phase inversion method. Polymer electrolyte with a mixture of 1.20 g of PVA/PAN with ratio variations of 10:90 and 20:80 and chitosan variations of 2.4 g; 2.8 g; and 3.2 g. Chitosan was also FTIR-characterized. Density and wÃ¡ter absorption of polymer electrolyte with chitosan composition of 2.4 g; 2.8 g; 3.2 g and PVA/PAN ratio of 10:90 were 0.824 g/mL; 1 g/mL and 1.51 g/mL and water absorption 28.571%; 38.333%; and 46.154%, respectively; and at PVA/PAN ratio of 20:80 were 0.734 g/mL; 1.03 g/mL and 1.096 g/mL and water absorption 62.5%; 66.667% dan 100%, respectively. Best physical property was obtained with the incorporation of 2.4 g of chitosan and 10:90 PVA/PAN ratio.

Palm oil mill effluent (POME) is the main waste generated from the palm oil industry. LCPKS has a COD level of 57,000-60,400 mg/L. High levels of COD can harm the environment. LCPKS treatment techniques generally use a combination of anaerobic and aerobic waste treatment methods. The anaerobic process has been conducted using a UASB-HCPB reactor. But, the COD levels of anaerobic results have not reached the quality standards so that further processing is needed. Microalgae have the potential to reduce contaminant levels in wastewater. Chlorella vulgaris microalgae is a microalgae that is widely used in wastewater treatment. This study utilized Chorella vulgaris in reducing the COD levels of the effluent of the UASB-HCPB biogas fermentor with variations in lighting intensity and variations in the ratio of effluent to microalgae. It was found that the lighting intensity of light:dark (24:0) hours provided optimal microalgae growth so as to provide the best COD reduction with a COD reduction efficiency of 87.5%. The ratio of microalgae to effluent of 1000 mL: 500 mL showed the best COD reduction with an efficiency of 93.75%.

Unsold vegetable waste from agricultural produce often rots and ends up being discarded at landfills, increasing waste volume and potentially causing environmental problems. To address this issue, vegetable waste can be processed into useful and marketable products such as bioethanol. Bioethanol is a renewable energy source obtained through the fermentation of biomass, including vegetable waste such as potatoes, tomatoes, carrots, mustard greens, and cabbage. In this community service program, an e-Bio production unit with a processing capacity of 5 liters has been designed, utilizing vegetable waste as raw material. The unit consists of pre-treatment equipment, a fermenter, and a distillation unit. The pre-treatment equipment includes an initial cooking tank, a crusher, and a pressurized tank. The fermenter tank is equipped with two manual paddle-type agitators with a diameter of 30 cm. Meanwhile, the distillation tank is made of stainless steel and equipped with a heater to heat the fermented solution and a cooling water tank to cool the evaporated e-Bio. The unit achieves a distillation efficiency of 95% with a production rate of 0.475 L/hour, producing 0.95 liters of ethanol after two hours of operation. The goal of this program is to implement the e-Bio production unit by utilizing vegetable waste as raw material, increase community or farmer income through e-Bio sales, and reduce the environmental impact caused by vegetable waste disposal.

Community service aims to provide tangible contributions by offering innovative solutions to various local problems. One of Indonesia’s major issues, especially in urban areas, is waste management. Every day, tons of waste are produced, but it is often disposed of without further processing. A lack of public knowledge about organic waste management is a key contributing factor. In Tadukan Raga Village, Deli Serdang Regency, Universitas Sumatera Utara implemented a community service program to educate residents on environmentally friendly organic waste processing using maggots. Maggots can decompose organic waste and produce residue that serves as fertilizer, while the larvae themselves are valuable as fish feed. Additionally, residents were trained in straw mushroom cultivation to maximize the benefits of organic waste. The program successfully increased public awareness of waste management, produced economically valuable products, and established maggot-based production facilities. This initiative not only reduced environmental impact but also supported local economic sustainability. Recognizing further potential for development, additional training continues to be conducted to strengthen the program’s outcomes.

Biogas is renewable energy that can be used as substitute of LPG and generator fuel. The utilization of waste into biogas has been implemented in Tadukan Raga Village, Sinembah Tanjung Muda (STM) Hilir District, Deli Serdang Regency since 2018 by building a facility for processing biomass into biogas by utilize rumen waste and cow dung at pilot scale. This facility has been handed over by the Ministry of Environment and Forestry to the community to manage independently. However, there is a problem in the lack of understanding of the community in the management, development and maintenance of this facility. This problem resulted in the abandonment of the biogas plant so that production and operations not running and some equipment requiring repairs. The purpose of this program is to strengthen and empower observer groups and users of biogas production facilities in Tadukan Raga Village. Therefore it is necessary to carry out: an analysis of the sustainability of the biogas plant program and the use of biogas as an alternative to overcoming livestock manure pollution in the program of Desa Binaan USU 2022, repair of biogas reactor and piping and the use of biogas stoves modified from LPG stoves.
