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

Papua province has nine small islands that are inhabited, but there is no access to electricity on these islands. The solution is the use of sea wind as a source of energy for a small power plant. This study aims to determine the potential of sea wind as an alternative source of electrical energy on the north coast of Papua Province. Data Measurement is carried out using an HP-866B anomometer on a hill near the coast to maximize the sea wind. There are two methods used in this research: the minimum-maximum value to determine the wind speed range and linear regression to determine the distribution pattern of the wind. The range of the sea wind is 0.2–6.18 m/s. If the minimum speed is limited to 1.6 m/s, then the range of kinetic energy is 5.59–322.22 Joules/s, mechanical power is 5.59–322.22 Watts, and actual power is 0.57–33.13 Watts. Meanwhile, the pattern shows that the sea wind from the north coast of Papua Province blows with two trends: constant and increasing, specifically in the afternoon and evening. Based on that, the development of a wind power plant on the north coast of Papua Province can be carried out using a multi-turbine system to increase the actual power that can be obtained.

Abstract

The need for electrical energy in Nehibe village is currently increasing along with the increase in population and new households. The demand for electricity in this village reaches 18 kW, with an average power per household of 450 VA. The problem is that Hachakwa Nehibe Micro Hydro Power Plant (PLTMH), which is very close to the village, has a capacity of only 10 kW. Based on that problem, this study aims to design a peltor turbine with two nozzles for the new 26 kW PLTMH. This power plant uses the water from the Tena Mroway and Yora Mroway rivers, which are located 2 km from the end of the village, as a new source of energy. This design of the turbine is based on the mathematical equations, measurement data of the head, and the flow of the rivers. This research shows that the Pelton turbine with two nozzles (nj), 0.032 meters of jet diameter (Dj), 0.330 meters of runner diameter (Dr), 0.096 meters of bucket diameter, and 21 buckets can produce 26 kW of power with 60 ltr/sec of river flow and 77 meters of head height. This specialization can be used to develop the new PLTMH in Nahibe Village.
