Abstract

This Community Service activity addresses sheep manure waste issues at Umroh Farm, Patumbak Village, Deli Serdang. Waste buildup causes odor and environmental pollution despite its potential as biogas material. The solution was implementing appropriate technology by constructing a household-scale biogas reactor. Activities included participatory training, equipment assembly, and field trials. The digester, with a ±200-liter capacity, was made from plastic drums and equipped with input-output, cleaning, and gas collection lines. The implementation produced an average of 0.015 m³ of biogas per hour, with fire ignition lasting 1–2 seconds. The program reduced livestock waste, improved farmers’ awareness and skills and supported clean energy and climate change mitigation goals. Its success shows that simple biogas technology can provide an integrated solution for environmental management and community empowerment.

Abstract

Briket aromaterapi merupakan inovasi untuk meningkatkan nilai tambah dari briket arang, briket aroma terapi merupakan campuran dari limbah mebel dan jahe sebagai aromaterapinya dengan perekat tapioka dan bubur koran. Pengabdian kepada masyarakat ini bertujuan membantu mitra memanfaatkan limbah mebel menjadi produk alternatif yang ramah lingkungan dan memiliki nilai jual. Metode yang diterapkan, dengan mengenalkan dan memberikan informasi melalui ceramah serta diskusi, melatih dan melakukan eksperimen. Dalam kegiatan ini, masyarakat dan pengusaha mebel diminta secara langsung terlibat aktif mengikuti kegiatan ini sehingga dapat meningkatkan pemahaman, pengetahuan dan keterampilan dalam memanfaatkan limbah mebel menjadi produk breket aromaterapi yang memiliki nilai tambah. Dari beberapa percobaan yang sudah dilakukan maka didapatlah kompisisi perbandingan sebagai berikut: bubuk briket halus dan tapioka = 8:1, tepung tapioka dan air = 1:7, tapioka dan bubur koran = 1:1, adonan (bubuk briket + tapioka + bubur koran) dan jahe parut = 1:1. Briket aromaterapi memiliki keuntungan: bahan yang murah dan ekonomis, tidak beracun, ramah lingkungan, tahan lama, aman bagi kesehatan, tanpa tambahan bahan kimia, memiliki aroma menyegarkan dan menjaga kesehatan pernapasan. Dengan adanya briket aromaterapi ini Kemang Jaya Mebel memiliki suatu usaha baru dalam memanfaat limbah mebel tersebut.

Abstract

This study aims to analyze the working postures of laboratory analysts using the Rapid Upper Limb Assessment (RULA) method to identify the risk of Musculoskeletal Disorders (MSDs). Observations were conducted during primary laboratory activities to document body posture, joint angles, and work duration. The RULA assessment indicated moderate to high risk, suggesting the need for immediate corrective actions. Major contributing factors to MSD risk included bent working postures, repetitive arm movements, and non-ergonomic workstation design. Recommended improvements involve workstation adjustment, posture correction, and the application of ergonomic principles. This study is expected to support MSD prevention efforts and improve comfort and productivity among laboratory analysts.

Abstract

This Community Service Program focuses on managing micro-business-scale food production waste. The activity was carried out at Pakcik Tanjung Morawa Roti MSMEs in the Tanjung Morawa area. These MSMEs produce used eggshell waste and cooking oil every day. The waste has not been managed systematically and could pollute the surrounding environment. This program aims to increase partners' awareness of the value of organic waste. The program also introduces the concept of waste utilization as an alternative energy source.  The activity's approach is educational and informative through field visits. The methods used include observation, interviews, and two-way discussions. The team conveyed the potential of eggshells as a source of calcium oxide.  Calcium oxide serves as a biodiesel catalyst from waste cooking oil. Activities do not yet include technical training or process demonstrations. The activity results showed an increase in the partners' initial understanding. Partners show interest in sustainable waste management. This program results in a mapping of potential waste and partner needs. The output of the activity is documented in reports and follow-up plans. This program is the foundation for the next stage of technology assistance. A simple approach is assessed based on the partner's capacity. Activities support waste reduction and community-based environmental education.

Abstract

The company faces a recurring issue related to product defects, which affect both production efficiency and customer satisfaction. To address this problem, this study applies a causal and experimental research approach using the Taguchi Method as a systematic tool for process optimization and quality improvement. The Taguchi Method is employed to identify the optimal combination of process parameters that significantly influence the quality of cardboard boxes while minimizing defects and production variability. Based on the results of data processing and analysis, it can be concluded that the optimal combination of factor levels that significantly influence the improvement of carton box product quality, as determined through the Taguchi experimental design, is Speed at level 2 (280 mpm), Air Supply at level 2 (0.88 MPa), and Steam Supply at level 2 (5 MPa). These optimal conditions demonstrate the most effective balance between production efficiency and product consistency, and must be properly maintained to ensure stable and high-quality output. Furthermore, improvement efforts based on the Taguchi method emphasize the importance of the human factor or operator in sustaining these optimal settings. Operators must be trained to respond appropriately to changes in process parameters and to maintain consistent conditions during production. The results of this research confirm that the Taguchi Method provides a robust, data-driven framework for continuous improvement, helping  reduce defects, optimize process performance, and achieve sustainable quality enhancement in its cardboard manufacturing operations
