Abstract

Penyejuk udara biasa yang di kenal dengan istilah AC semakin banyak beredar karena dapat memberikan kenyamanan pada manusia. Untuk memperoleh kenyamanan pada manusia memiliki batas temperatur dan kelembaban, banyak faktor yang dapat mempengaruhi kenyamanan manusia baik temperatur maupun kelembaban. Berdasarkan hal tersebut dilakukan penelitian sistem pendingin yang akan berpengaruh terhadap temperatur, RH (Relative Humidity) dan humidity ratio pada AC dengan kapasitas 18000 Btu/hr dengan volume ruangan 200m3. Berdasarkan hasil penelitian di dapat bahwa mesin pendingin yang sudah berusia 8 tahun masih mampu menjaga temperatur dan kelembaban nyaman manusia, temperatur dapat mencapai 22,30C dan pengurangan kelembaban maksimal mencapai 16,4 gr/kg.

Abstract

Small-sized fire fighting vehicles such as the three-wheeled Viar are a practical solution for reaching narrow and dense locations. This study aims to compare the water pump engine based on the discharge generated when using two types of fuel, namely Pertalite and LPG gas, in the design of the three-wheeled Viar Fire Fighting System. The main focus of the research is on how much water discharge can be generated and how the operational cost efficiency of each fuel. The method used is direct experimentation, where the pump is run at a fixed engine speed of 2400 RPM. The volume of water pumped is measured at a certain duration to obtain the discharge value. In addition, the fuel consumption was analyzed and the cost incurred in one pump cycle was calculated. In order for the LPG test to run optimally, the carburetor was modified to adjust the characteristics of the gas fuel.

Abstract

The community service program, in collaboration with Madrasah Tsanawiyah Al-Amalul Khair in Palembang, aims to address the urgent need for an efficient water pump system, replacing the existing labor-intensive, unhygienic manual pulley system. The school, with approximately 388 students and 27 staff, faces difficulties meeting daily water demand of 1,500–3,000 liters, resulting in long queues and hygiene issues that disrupt religious and learning activities. The program's objectives include designing an energy-efficient pump with a capacity of at least 0.8 liters/second, providing a 1,500–3,000 liter storage tank and automatic sensors, and offering training on pump operation, maintenance, and troubleshooting. Additionally, sustainability will be ensured through manuals, internal technical teams, and partnerships. The method involves outreach, training workshops, installation, mentoring, and performance evaluation. Expected outcomes are a reliable, hygienic, energy-efficient water pump system, improved ablution facilities, operational manuals, a trained technical team, and enhanced capacity to manage water facilities, reducing costs. Ultimately, the program will improve religious practices, health standards, and overall comfort in the learning environment.

Abstract

Charcoal briquettes are an environmentally friendly alternative energy source; however, conventional production is hampered by the slow and labor-intensive manual molding process. This study aims to improve production efficiency for farmers in Lalan, Musi Banyuasin, by designing and testing a screw-type charcoal briquette press machine powered by an electric motor. The machine is designed with a capacity of 10 kg per cycle, using coconut shell charcoal powder as the test material. The research methods include the design, fabrication, and performance testing through a comparative study of the machine and manual molding processes, as well as product uniformity evaluation. The results show a significant increase in production rate. The screw machine is able to produce an average of 24 briquettes in 50 seconds, while the manual method only produces 5 briquettes in the same time, indicating an approximately 4.8-fold increase in output. The machine's measured capacity reaches 32.29 kg/hour under extended testing conditions, and the briquettes produced are uniform according to the mold. Based on the test results, the machine demonstrates greater efficiency as the molding time increases, with a total output of 144 briquettes in 300 seconds, while the manual method only produces 30 briquettes in the same time. This study concludes that the implementation of the screw-type briquette press machine effectively accelerates the production process, reduces reliance on manual labor, and has the potential to increase the economic value of biomass waste for small- to medium-scale enterprises.
