Tujuan dari pengabdian masyarakat ini adalah untuk memberdayakan petani pinang dengan tujuan mempercepat proses pengupasan pinang dan meningkatkan kinerja petani. Kegiatan pengabdian ini dilaksanakan di Gampong Tualang Dalam, Kecamatan Serbajadi, Kabupaten Aceh Timur, Provinsi Aceh. Salah satu permasalahan yang dihadapi oleh petani pinang adalah proses pengupasan buah pinang yang belum efisien dan masih menggunakan alat-alat sederhana seperti pisau. Oleh karena itu, tujuan dari kegiatan pengabdian ini adalah merancang dan membuat alat pengupas/pembelah buah pinang dengan menggunakan metode mekanis. Metode kegiatan pengabdian ini terdiri dari tahap persiapan, pelaksanaan, evaluasi, dan pemantauan. Kegiatan pengabdian ini melibatkan mahasiswa dan dosen, serta melibatkan kelompok mitra petani yang tergabung dalam kelompok tani pinang. Proses pembuatan alat mekanis ini dimulai dengan tahap perancangan, diikuti oleh pembuatan alat secara langsung yang melibatkan petani di desa tersebut. Selanjutnya, petani akan diajari cara menggunakan alat pengupas buah pinang ini. Alat ini digunakan dengan cara menekan buah pinang hingga terbelah menjadi dua. Setelah dibelah, buah pinang ditempatkan dalam wadah untuk diambil buah pinangnya. Hasil dari kegiatan pengabdian ini menunjukkan bahwa mitra petani pinang telah memperoleh pengetahuan tentang pembuatan dan penggunaan alat pengupas buah pinang, serta berhasil mengoperasikan alat tersebut. Pengabdian ini juga berhasil meningkatkan produktivitas kerja petani. Hasil pemantauan menunjukkan bahwa masyarakat puas dengan alat pengupas dan pembelah buah pinang ini karena mampu mempercepat kerja petani. Namun, hasil evaluasi menunjukkan perlunya pengembangan ulang untuk membuat mesin otomatis tanpa bantuan tenaga manusia.

The heat pipe (HP) is a fundamental heat transfer component frequently utilized for energy recovery in heating, ventilation, and air conditioning (HVAC). However, a heat pipe transmits heat from the hot side (evaporator) to the cold side (condenser), resulting in a temperature difference on both sides. There are numerous methods for measuring heat pipe performance. Using the temperature difference between the evaporator and condenser, the performance characteristics may be evaluated. The objective of this study is to compare the thermal performance of thermosiphon and commercial wick heat pipes (WHP) utilizing water as the working fluid and varying temperatures between the evaporator and condenser. The copper thermosiphon and commercial wick heat pipe had a diameter of 10 mm, a length of 800 mm, and a vacuum pressure of 5000 Pa. The filling ratios range between 30% and 50%, and it was evacuated at a pressure of 5000 Pa; the hot water temperatures at the evaporator were 30, 50, 70, and 90 ºC. Temperature was steadily increased every 30 minutes, and variations were observed at multiple places, including hot water, evaporator, and condenser wall. The average difference in temperature between the WHP and thermosiphon was around 0.6 degrees Celsius. The decreased temperature difference (T) indicates that the heat pipe is performing well. In addition, if the temperature difference is very great, the HP will dry up, therefore the WHP performs better than the thermosiphon.

The demand for electricity is continually increasing. Typically, electrical energy is generated using fossil fuels such as coal in thermal power plants. Generally, these power plants or other electricity generators supply power to densely populated areas such as large cities. Remote areas, however, often lack access to electricity due to their distance from urban centers. One solution to this issue is the development of micro-hydropower plants (MHPs). In MHPs, turbines are generally made of metal, which has high inertia and thus leads to lower efficiency. Therefore, this study replaces the turbine in an MHP with one made of fiberglass to assess the material's resistance to the water pressure in MHP operations. Based on the research conducted, the allowable stress for the fiberglass was determined to be 11.59801 MPa, with the water pressure applied to be 0.000985 MPa.

Renewable energy utilization has become a primary focus in addressing the negative impacts of fossil fuel usage for electricity needs. One proposed solution is using water flow energy through a Pelton turbine. However, traditional materials used in Pelton turbines, especially metals, have disadvantages such as high inertia and susceptibility to corrosion. In this study, we replaced the Pelton turbine's material with fiberglass composite, which offers lower inertia and better corrosion resistance. This study aims to evaluate the performance of the Pelton turbine using fiberglass composite material. Tests were conducted by connecting the turbine to a generator and installing three adjustable nozzles, divided into seven sections based on the number of nozzles opened. Voltage, current, and electric power were measured using a power meter. The results show that with a load consisting of LED light bulbs, the section with one nozzle open (Section 2) achieved the best power output of 1.11 watts, while the section with two nozzles open (Section 6) achieved the best power output of 1.66 watts. Without load, the highest voltage occurred in Section 2 with one nozzle open at 30.9 volts, while the highest power was recorded in Section 4 with two nozzles open at 31.26 volts

The existing drying system struggles with efficiency and costs, contradicting its intended resource-saving purpose. Addressing these issues could generate increased interest in its utilization. To tackle this, precise control of the dryer's temperature and optimization of the heat source are essential for obtaining accurate and real-time data. Employing a quantitative approach, the researcher conducted a case study, performing tests subsequent to the completion of the dryer's assembly. These tests encompassed temperature measurements on both the core and periphery of the paraffin medium, as well as at the lower, middle, and upper sections of the heat pipes. Diverse voltage levels (150V, 180V, 200V, 220V) and two distinct airflow velocities (1 m/s and 2 m/s) were implemented. The study yielded a noteworthy finding: at 200 volts and a 2m/s airflow, a stable temperature of 94.8 ºC was maintained for an impressive duration of 1 hour and 5 minutes during testing. This promising outcome holds significant implications for enhancing the system's efficiency.

Solar water heaters are widely utilized for domestic hot water production, leveraging solar energy as a renewable and sustainable resource. However, the intermittent nature of solar radiation limits their efficiency, particularly during periods of low solar intensity or at night. This study investigates the thermal performance enhancement of solar water heaters through the integration of phase change materials (PCMs), specifically paraffin, within flat plate collectors. The paraffin PCM is placed within an additional pipe in the collector to store excess thermal energy during peak sunlight hours and release it when solar radiation is insufficient. Experimental tests were conducted to measure temperature fluctuations, heat storage capacity, and overall system efficiency with and without PCM integration. The results indicate that the addition of paraffin PCM significantly improves the system’s ability to retain heat, maintaining water temperatures above 50 °C for extended periods and increasing the overall efficiency of the solar water heater by 17.10%. This study demonstrates the potential of PCM-enhanced solar water heaters in optimizing energy use and improving thermal efficiency, making them more effective in regions with variable solar exposure.
