Abstract

The demand for efficient distribution of oxygen cylinders at Abepura Regional General Hospital (RSUD Abepura) has been steadily increasing due to the growing needs of staff members and patients who expect high-quality service within the hospital premises. In response to this demand, this study aims to propose a transportation system that is not only automated but also time-saving, with the ultimate goal of enhancing medical services in a more efficient, eco-friendly, and safe manner. One of the main challenges faced in the distribution process is the hilly terrain surrounding RSUD Abepura. The presence of these hills makes it difficult to manually distribute the heavy 72 kg gas cylinders, which is the current method employed at the hospital. To overcome this challenge, this research suggests implementing an innovative solution—an electric trolley—that can effectively facilitate the distribution and flow of oxygen cylinders at RSUD Abepura. The findings of this study conclusively demonstrate that the electric trolley is not only a suitable but also a convenient solution for the operators and medical staff involved in the distribution process. By utilizing the electric trolley, they can distribute oxygen cylinders without facing any hindrances posed by the uphill roads, ultimately resulting in significantly improved time efficiency and service effectiveness at RSUD Abepura.

Abstract

Barapen, a cooking tradition in various indigenous Papuan communities. To date, various social science studies have been conducted to examine social values, business economics, and political economy. While research in the aspects of applied science has yet to be conducted to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs, this research was conducted. The purpose of this research is to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs. In this study, a square-shaped artificial pool (260 cm x 210 cm x 50 cm) with white batah stone walls was used to cook food in a barapen. On the four walls, a type K thermocouple is inserted to measure the temperature at 3 layers, which will be the object of research. The ingredients are vegetables, sweet potatoes, and chicken meat that has been cut and stoned. As a discussion, the temperature gradient between layers occurs due to the difference in the amount of volumetric heat against time in each layer. The difference in the amount of heat in each layer is due to the difference in the density of the hot vapor trapped in each layer. Thus, it can be said that the cooking of food in Barapen occurs due to natural heat convection.

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.
