Abstract

The influence of carboxymethyl cellulose (CMC) concentration derived from durian rind (Durio zibethinus) and temperature variations on coconut milk quality was investigated through three stages. The first stage involved the isolation of ?-cellulose from durian rind powder, which was analyzed using FTIR to confirm its identity as cellulose. In the second stage, a series of processes including alkalization with isopropanol and NaOH, carboxymethylation with NaMCA, and neutralization using 90% CH3COOH and ethanol were conducted, followed by purification with distilled water, centrifugation, and the addition of acetone. This resulted in CMC, which showed positive qualitative analysis and FTIR peaks similar to those of commercial CMC. The final stage focused on coconut milk production, where CMC was incorporated at concentrations ranging from 0.5% to 0.7%, and temperature variations were set at 16ºC, 25ºC, and 80ºC. The quality of the resulting coconut milk was assessed for stability, pH, viscosity, moisture content, protein content, fat content, free fatty acid content, and organoleptic properties. The optimal results were achieved with the addition of 0.7% CMC at 16ºC, yielding a stability percentage of 34.78% with a shelf life of 9.5 hours, a pH of 6.21, viscosity of 12.6138 x 10² cP, moisture content of 45.81%, protein content of 7.57%, fat content of 43.51%, and free fatty acid content of 1.402%. Organoleptic tests indicated that panelists favored the coconut milk with 0.7% CMC for its color and aroma. The quality analysis results for the coconut milk with CMC addition and temperature variations met the existing SNI standards.

Abstract

Arjuna Farm Sheep and Goat Farm produces goat milk products. Goat milk can be processed into various products, one of them is cheese. This community service activity through training in making cheese products from goat milk aims to provide assistance to farmers with a focus on processing fresh goat milk into quality cheese at Arjuna Farm. Cheese has a longer shelf life than milk. By turning milk into cheese, farms can extend the shelf life of their products. The problems identified include low knowledge and skills of farmers and limited access to appropriate materials and equipment. To overcome these problems, this activity offers several solutions, including training and workshops to improve farmers' knowledge and skills for making cheese from goat milk, direct assistance in the cheese processing process, and provision of simple materials and equipment. So that Arjuna Farm not only sells goat milk, but can also produce cheese and can reach a wider market segment. The methods used in this community service are training and practice, guidance, and monitoring and evaluation.

Abstract

Desa Dalig Raya in Simalungun Regency possesses significant potential in red ginger commodities; however, its utilization remains limited to raw product sales, resulting in low economic value added. This study aims to enhance community income through innovation in processing red ginger into value-added ginger candy based on local potential. The research employs a Participatory Action Research (PAR) approach, involving stages of situation analysis, production training, and business management assistance. The results indicate that the innovation of red ginger candy products improves community skills, increases economic value added, and creates broader market opportunities in functional food products. Furthermore, the program strengthens community economic independence through downstreaming strategies and collaborative partnerships. Overall, this initiative contributes to improving community welfare by optimizing local resources and promoting sustainable rural economic development.

Abstract

Kwala Gebang Village in Langkat Regency is a coastal community whose livelihood strongly depends on the capture fishery of rebon shrimp, the main raw material for a traditional shrimp paste (terasi) that has been produced through natural fermentation across generations, including by the Kelompok Tani Hutan (KTH) Kuala Indah. A flood disaster that struck the village at the outset of the program disrupted the production, distribution, and income of the partner group, prompting the International Community Service Collaboration Program between the Faculty of Vocational Studies, Universitas Sumatera Utara (USU) and Universiti Teknologi MARA (UiTM), Cawangan Pulau Pinang, Malaysia, to focus on post-flood economic recovery through three main solutions: strengthening business management, improving packaging quality using a vacuum sealer and official labeling, and product diversification through the development of shrimp paste powder. This study employs a Participatory Action Research (PAR) approach, covering situation analysis, training module development, procurement of production equipment, hands-on training, and mentoring. As of the 80% fund-disbursement stage, the program has completed initial coordination and needs mapping, training module preparation, procurement of most supporting materials and equipment, and part of the training and mentoring activities for KTH Kuala Indah members. The results show improvement in hygienic packaging standards, the emergence of a new value-added product in powdered form, and strengthened financial management capacity among the partner group. The program is expected to support post-flood economic recovery while contributing to the achievement of the Sustainable Development Goals (SDGs 1, 8, 9, 12, 14, and 17).

Abstract

The massive flooding that struck Medan in November 2025 severely affected the Tanjung Gusta neighborhood in Medan Helvetia subdistrict, prompting the Al-Yahdi Medan Foundation to serve as an evacuation center. It also contaminated residents' clean Water sources, while the public still judges Water safety by visual clarity alone, without understanding pH as a key chemical indicator. This community service activity, under the Pioneer Service Program of the Vocational Faculty, Universitas Sumatera Utara, aimed to enhance the knowledge and skills of teachers, students, and parents at Al-Yahdi Foundation in assessing Water potability after the flood through education on pH parameters and training in portable pH meters, complementing simpler pH indicator (litmus) paper. Conducted at Al-Yahdi Foundation from April to November 2026, the activity comprised coordination, instrument design and validation, outreach, demonstrations, hands-on training, distribution of instruments and manuals, mentoring, and pretest–posttest evaluations. Average comprehension scores rose from 43.8 ('insufficient') to 87.0 ('good'). pH of Water samples from partner communities ranged from 5.9 to 7.2, with some outside the safe range set by Indonesia's Ministry of Health (6.5–8.5). This initiative effectively raised public awareness and fostered self-reliance in testing Water quality before consumption during post-flood recovery, supporting Sustainable Development Goals (SDGs) 3 and 6.
