Abstract

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.

Abstract

Universitas Samudra sangat mendukung pelaksanaan kampus merdeka belajar seperti yang diinstruksikan oleh Kemendikbud. Khususnya Fakultas Teknik telah mengupayakan pencapaian kurikulum merdeka belajar sebagai wujud implementasi kampus merdeka, salah satunya melalui program KKN tematik/membangun desa. Mahasiswa merupakan generasi muda yang memiliki intelektual dan semangat yang tinggi dan harus mampu memberi andil terhadap masalah pembangunan bangsa dan negara. Dalam kegiatan ini mahasiswa dapat mengembangkan rasa kepekaan dan solidaritas terhadap masyarakat sebagai makhluk sosial dalam membantu proses pembangunan. KKN-Tematik adalah salah satu program Pengabdian pada Masyarakat yang telah dilakukan oleh mahasiswa Fakultas Teknik Universitas Samudra. Pelaksanaan kegiatan dilakukan bertempat di Desa Matang Peulawi yang berada di kecamatan Peureulak, Kabupaten Aceh Timur, provinsi Aceh, Indonesia. Secara geografis Desa Matang Peulawi terletak pada bagian utara Kuala Bugak atau pun pada bagian barat Pasir Putih yang merupakan bagian dari Kabupaten Aceh Timur. Termasuk ke salah satu Desa pemasok ikan kecamatan Peureulak. sok ikan kecamatan Peureulak.

Abstract

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

Abstract

The manufacturing industry is growing rapidly, especially in terms of industrial workshops. According to BPS data for 2017, in 2016 the development of the manufacturing industry increased by 4.74%. Engineering design or machine design is a series of processes that translate the results of a system into performance, to explain work in detail on the components used. Mechanical pressing is the process of extracting fat or oil through pressure applied to grains with an oil content of around (30%-70%). The aim of the research is to design a machine for squeezing avocado seeds into oil using a screw press, to obtain the length of time for pressing avocado seeds using a screw press and the percentage of biodiesel raw material oil obtained from avocado seeds in 1 kg after going through degumming. This research was carried out using the machine design method, calculating the length of pressing time and the amount of avocado seed seepage. The load pressure on the press is 360 N/m with an electric motor capacity of 0.88 HP and a rotation speed of 17.5 ????????m. Pressing 1 kg of avocado seeds is 58:39 seconds then the raw material for biodiesel oil is 23 grams/1 kg.

Abstract

This research created an innovative single-stage U-type Savonius wind turbine with water hyacinth composite material, intended for low wind speeds. With the steps of wind speed measurement, turbine rotation monitoring, and power measurement, interesting results such as a wind speed of 4.52 m/s producing a power of 5.17 volts were revealed. The significance lies in the potential of the water hyacinth composite turbine in utilizing low wind speeds to generate electricity. The conclusion notes the achievements in the manufacturing process of Savonius turbine blades and suggests that these findings provide an important basis for the development of composite-based wind turbines as an environmentally friendly renewable energy source.

Abstract

The scarcity of fossil fuels, environmental concerns, and the sharp rise in fossil fuel prices have driven scientists to search for alternative fuels. The characteristics of biodiesel have made the quest for high-quality biodiesel production particularly appealing. The use of waste cooking oil is a key component in reducing biodiesel production costs by 60-90%. Researchers have employed various types of transesterification reactions with both homogeneous and heterogeneous catalysts for biodiesel production; in this study, a 0.5% NaOH catalyst is used. The objectives of this study are to produce biodiesel fuel based on waste cooking oil, evaluate the impact of reaction time variation on the oxidation value and acid value of biodiesel produced from waste cooking oil, and statistically test the effects of reaction time on the oxidation value and acid value of biodiesel produced from waste cooking oil using analysis of variance (ANOVA). The optimum yield was obtained at a reaction time of 90 minutes, achieving 97%. The results for acid number and oxidation value for various reaction times complied with ASTM, EN, and SNI standards. Linear regression analysis of ANOVA for the acid number concluded that the P-value t3 is 0.399, which is greater than Alpha = 0.05, indicating that the variation in reaction time does not have a significant effect on the acid number. Linear regression analysis of ANOVA for the oxidation number concluded that the P-value t3 is less than Alpha (0.047 < 0.05), indicating that reaction time has a significant effect on the oxidation number.
