Abstract

This study examines the production of briquettes based on agricultural waste from sago pulp and coffee grounds using natural sago flour as a binder, through a laboratory experimental approach. The analysis covers the physical and chemical characteristics, as well as the thermal performance of 3 cm cube-shaped briquettes. The results show that coffee pulp briquettes have the highest heat transfer rate (0.528 Watts) and the highest calorific value (5018 kcal/kg), indicating superior combustion efficiency compared to sago pulp briquettes (0.205 Watts; 4856 kcal/kg) and mixed briquettes (0.347 Watts; 4966 kcal/kg). These differences in characteristics were influenced by the composition of the materials, while the size of the briquettes affected the ignition time. Overall, all types of briquettes showed potential as an environmentally friendly alternative energy source based on local biomass.

Abstract

Access to clean water is a fundamental necessity that underpins effective public health services and the operational efficiency of health facilities, including the Bonggo Health Center in Sarmi Regency. Recognizing the importance of reliable clean water access, a community assistance initiative was launched to establish a sustainable water installation system at the Bonggo Health Center. This initiative is crucial to enhancing the health center’s ability to deliver quality healthcare services, as safe, clean water is essential for various healthcare functions, from sanitation to patient care. The primary aim of the assistance program is to equip the Bonggo Health Center with a dependable source of clean water, ensuring it meets health and safety standards for use in medical services. To achieve this goal, the implementation method was carefully structured, involving several sequential steps. First, the service team conducted a comprehensive location survey to assess the water requirements and potential challenges. Following this, the team engaged in in-depth problem discussions, planning sessions, and preparatory work to lay the groundwork for the installation. The actual construction of the water installation was then carried out, followed by rigorous testing and evaluation to ensure functionality and quality. Through close collaboration with the Armopa Village community, the service team successfully completed a fully operational clean water installation. This unit now provides a reliable supply of high-quality water for the Bonggo Health Center, significantly improving the center’s capacity to serve the healthcare needs of the surrounding community. This installation not only meets immediate needs but also sets a foundation for sustained health service enhancements and community well-being in the region.

Abstract

Kualitas jagung yang dihasilkan oleh para petani sangat dipengaruhi oleh proses pengeringan pasca panen. Selain mengandalkan pengeringan langsung di bawah panas matahari, petani juga sangat membutuhkan alat pengering yang memadai, terutama jika masa panen berlangsung di musim hujan. Kegiatan ini bertujuan untuk memperkenalkan pengering tenaga surya (solar dryer) kepada masyarakat petani jagung, khususnya pada Kelompok Tani Berkat Rama yang berkedudukan di Kampung Bibiosi, Distrik Arso, Kabupaten Keerom sebagai salah satu sentra jagung di Jayapura. Pada kegiatan pengabdian ini, solar dryer yang disosialisasikan dilengkapi dengan kolektor sekunder dan turbin ventilator. Berdasarkan hasil penelitian sebelumnya, proses pengeringan menggunakan solar dryer dengan kolektor sekunder dan turbin ventilator akan berlangsung lebih cepat serta kualitas produk hasil pengeringan akan lebih baik karena temperatur di dalam ruang pengeringan dapat terjaga (tidak terlalu tinggi). Selain itu dengan menggunakan solar dryer maka proses pengeringan akan aman dari gangguan hujan dan hewan/ternak. Kegiatan PKM ini mendapat sambutan dan animo yang baik dari para petani jagung yang tergabung dalam Kelompok Tani Berkat Rama dengan mengikuti kegiatan sosialisasi hingga selesai. Kelemahan dari solar dryer adalah daya tampung yang masih terbatas sehingga masyarakat petani mengusulkan agar bisa dibantu oleh pemerintah setempat dalam hal pengadaan alat dan bahan untuk membangun sebuah alat pengering jagung yang berukuran memadai.

Abstract

Technical skills in lathe machine operation are highly demanded in the manufacturing industry, particularly in the production of machine components and other equipment. However, in Heram District, Jayapura City, access to technical training remains limited, resulting in low competitiveness among the local workforce. The lack of training facilities and qualified instructors has become a major obstacle in developing the skills of productive-age youth. Therefore, basic training in lathe machine operation serves as an important step in improving the quality of human resources, particularly for productive-age youth in Heram District, Jayapura City. The objective of this community service program is to equip productive-age youth in Heram District with fundamental skills in lathe machine operation, thereby enhancing their employment opportunities and economic independence. The methods implemented in this program include: identifying training participants who meet the productive-age criteria; providing training facilities and equipment, including lathe machines, safety gear, and training modules; coordinating with competent instructors in the field of machining; delivering the training through both theoretical and practical sessions with a composition of 30% theory and 70% practice; and conducting evaluations through theoretical and practical examinations to assess participants’ competencies after the training. Based on the post-training evaluation results, participants demonstrated a solid understanding of the basic concepts in theory, and most were able to perform basic turning operations accurately. The training was highly relevant to participants’ needs, and the majority expressed satisfaction with the program. The final evaluation concluded that, on average, participants achieved good to excellent scores, with high satisfaction ratings for material delivery, instructor preparedness, practical sessions, and the facilities provided.
