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.

This community service activity aims to find solutions to the problems faced by the Aisyiyah Organization mothers in Kampung Dadap, Medan, regarding the utilization of kasgot, a residue from household organic waste processing using Black Soldier Fly (BSF) maggots. The partners own agricultural land that requires additional nutrients to produce high-quality crops. Kasgot fertilizer is rich in amino acids and microorganisms that enhance soil nutrients without harming the environment. To reduce chemical fertilizer use, partners were trained to process kasgot with starch, molasses, and rice bran into solid granular organic fertilizer. The outcome is an eco-friendly, sustainable organic fertilizer.

Cempedak peel contains 38.85% pectin compounds and has the potential to become biofilm raw material. The characteristics of pectin-based biofilm can be improved by the addition of a glycerol plasticizer. This study aims to determine the effect of variations in glycerol concentration (0%; 3%; 5%; 7% and 9%) on biofilm charactersitics and biofilm application on the shelf life of mango fruit. Pectin was extracted using 5% citric acid at 85°C or 90 minutes. Biofilms were applied on mango fruit for 8 days. Analysis of pectin compounds showed a yield 22.09%; ash content 7.40%; equivalent weight 588.235 mg; methoxyl content 6.20%; galacturonic acid content 36.12%. Analysis of physical properties and biofilm application on mango fruit showed a density value of 2.833 g/mL; water solubility 79.41%; mango weight loss of 33.47%; and a deacrease in vitamin C of 5%. SEM-EDX analysis showed the pectin particles were homogeneous fine grains and dominated by the element of oxygen (O) 88.84%. FTIR analysis of cempedak fruit peel pectin and biofilm showed functional groups of O-H; C-H (methyl); C=O; C-O; C-C.

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.

Kegiatan Pengabdian kepada Masyarakat (PKM) REHEAT (Reusing Cooking Oil as Alternative Household Fuel in Response to the Energy Crisis) bertujuan memanfaatkan minyak jelantah (Waste Cooking Oil, WCO) sebagai bahan bakar alternatif kompor rumah tangga melalui pemberdayaan masyarakat bersama Aisyiyah Kampung Dadap. Minyak jelantah yang dikumpulkan dari dapur rumah tangga diolah melalui penyaringan sederhana dan diuji pada kompor berbasis WCO. Program ini juga melibatkan pelatihan teknis kepada ibu-ibu Aisyiyah terkait pengolahan dan penggunaan WCO. Hasil uji coba menunjukkan bahwa WCO mampu menghasilkan nyala api stabil dengan efisiensi yang memadai untuk aktivitas memasak dasar. Program ini memberikan manfaat ganda, yaitu mengurangi pencemaran lingkungan akibat pembuangan minyak bekas serta menekan biaya energi rumah tangga. Tantangan utama yang ditemui adalah kualitas minyak yang bervariasi dan keterbatasan pengumpulan rutin.Ke depan, penguatan sistem pengumpulan minyak serta pengembangan desain kompor yang lebih efisien diharapkan dapat meningkatkan keberlanjutan program. Model REHEAT berpotensi direplikasi di komunitas lain sebagai penerapan ekonomi sirkular yang mengintegrasikan aspek lingkungan, energi, dan pemberdayaan masyarakat.
