Permasalahan limbah serbuk kayu yang melimpah di Desa Tadukan Raga, Kabupaten Deli Serdang, membuka peluang untuk pengembangan energi terbarukan melalui produksi Wood PELLET (Productive Energy From Low-Cost Lumber Extraction Techniques). Limbah serbuk kayu yang selama ini tidak memiliki nilai jual optimal diolah menjadi bahan bakar alternatif berkalori tinggi menggunakan teknologi inovatif. Program pengabdian masyarakat ini bertujuan meningkatkan perekonomian masyarakat sekaligus mendukung efisiensi energi. Solusi yang ditawarkan mencakup pemberdayaan masyarakat, pengembangan teknologi Wood PELLET, serta penyediaan prototipe tungku Fuel Wood yang mendukung efisiensi pembakaran. Hasil kegiatan mencakup survei awal untuk mengidentifikasi potensi biomassa dan kebutuhan masyarakat, serta Focus Group Discussion (FGD) dengan perangkat desa. Sosialisasi dan pelatihan diberikan kepada 20 warga Desa Tadukan Raga. Pelatihan ini melibatkan praktik langsung pembuatan Wood PELLET dan demonstrasi prototipe tungku Fuel Wood yang didesain untuk efisiensi pembakaran. Prototipe ini memiliki keunggulan dalam efisiensi panas, kemudahan penggunaan, dan kesinambungan operasi. Keberlanjutan program diwujudkan melalui pelatihan dan pengawasan berkelanjutan oleh tim Universitas Sumatera Utara, memastikan transfer teknologi dan peningkatan kapasitas masyarakat. Program ini tidak hanya meningkatkan nilai ekonomis limbah serbuk kayu tetapi juga mendukung transisi energi berkelanjutan di tingkat lokal.

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.

This research explores the role of effective communication in character education to enhance nationalism among students at SMP Swasta Islam Terpadu Jabal Noor. Utilizing a descriptive qualitative approach, data were collected through observations and in-depth interviews with the principal, vice principal, and homeroom teacher. The findings reveal that effective communication strategies, including lectures, group discussions, and the use of digital media, play a pivotal role in embedding nationalistic values within students. The study highlights that integrating digital tools in delivering character education makes learning more engaging and impactful for digital-native students. Despite challenges such as limited infrastructure and digital literacy, the approach effectively instills moral and civic virtues. This research emphasizes the need for innovative communication strategies in Islamic educational institutions to bridge religious values and nationalism, fostering a harmonious and unified generation prepared to navigate the complexities of modern society.

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.
