Abstract

The source of lighting in ships can be sourced from electrical energy generated by using generators or now can utilize new renewable energy, such as solar energy using PV. Based on the existing potential, Indonesia has good solar energy potential. The measurement results show that the potential for solar energy reaches 6.37 kWh/m2/day. This potential can certainly be utilized in the marine and fisheries world. The utilization of PV as a source of electrical energy on fishing boats is expected to help support government policies in terms of the blue economy and overcome the limited number of fossil energy sources. In this study, the installation of PV with a size of 100 WP was installed on fishing boats. The need for electrical energy for PV energy output shows that it can meet 50.52% of electrical energy needs. This result is supported by the Wilcoxon test that electrical energy needs can be met by PV with a p < 0.005. The results of the economic analysis also show that the use of solar energy as a source of electrical energy provides an IRR of 9%, with a payback period of 8.87 years.

Abstract

Fishing by small and large-scale fishers must be supported by vessels and proper fishing gear. Ships have advantages in transportation and catching fish because they have a minor accident rate compared to other transportation modes. After all, ships are equipped with facilities for prevention and control. This is so important in fishing activities by fishers. A fisherman in Tablolong Village is a one-day fishing fisherman who catches fish around East Nusa Tenggara. The significant potential of the sea has made fishing activities one of the livelihoods for the community. However, if the ship is damaged, the fishermen cannot carry out fishing activities. This will affect their economy. This community service provided training and maintenance of single-cylinder boat engines on two damaged fishing boats. All fishermen participated in this activity and received good appreciation, and this training immensely helped the community. The results of this training have a good impact on the community. In the evaluation results, fishers can make repairs and carry out maintenance independently on their vessels. --- Penangkapan ikan oleh para nelayan skala kecil dan besar harus didukung dengan kapal dan alat tangkap yang layak. Kapal mempunyai keunggulan dalam pengangkutan dan juga dalam menangkap ikan karena memiliki tingkat kecelakaan yang kecil dibandingkan dengan moda transfortasi lainnya, karena kapal dilengkapi sarana untuk pencegahan dan penanggulangannya. Hal ini begitu penting dalam kegiatan penangkapan ikan oleh para nelayan. Nelayan di Desa Tablolong merupakan salah satu nelayan one day fishing yang melakukan penangkapan ikan di sekitar Nusa Tenggara Timur. Besarnya potensi laut yang ada menyebabkan kegiatan penangkapan ikan menjadi salah satu mata pencaharian bagi masyarakat. Namun jika terjadi kerusakan kapal, maka para nelayan tidak bisa melakukan kegiatan penangkapan. Hal ini akan berpengaruh kepada perekonomian mereka. Pengabdian kepada masyarakat ini dilakukan dengan memberikan pelatihan dan perawatan mesin kapal satu silinder pada dua kapal nelayan yang mengalami kerusakan. Pada kegiatan ini diikuti oleh seluruh nelayan dan mendapatkan apresiasi yang baik, dan masyarakat sangat terbantu dengan adanya pelatihan ini. Hasil pelatihan ini memberikan dampak yang baik bagi masyarakat. Pada hasil evaluasi para nelayan dapat melakukan perbaikan dan melakukan perawatan secara mandiri pada kapal-kapal mereka.

Abstract

Keterbatasan BBM dan harga yang meningkat mempengaruhi perekonomian para nelayan di Indonesia. BBM ini memegang peranan penting dalam kehidupan para nelayan karena dipergunakan untuk menggerakan mesin induk dan juga generator di atas kapal. Untuk mengatasi permasalah terebut maka dicoba untuk mensosialisasikan PLTS dan Lacuda dalam mengurangi kebutuhan BBM di atas kapal. Sistem ini dapat mengganti penggunaan generator di atas kapal dan membantu proses penangkapan ikan para nelayan. Kegiatan pengabdian diberikan kepada para nelayan di Desa Oemata Nunu, dengan metode pemaparan materi, wawancara dan kuesioner. Kegiatan pengabdian kepada masyarakat untuk meningkatkan pemahaman keekonomian penggunaan PLTS dan Lacuda pada masyarakat Desa Oemata Nunu, Kupang Barat, Nusa Tenggara Timur berjalan dengan baik dan menunjukan adanya peningkatan pemahaman masyarakat. Hasil uji Wilcoxon, diperoleh nilai signifikan 0,001 (p < 0,05), dengan demikian disimpulkan bahwa terdapat perbedaan pemahaman yang bermakna antara sebelum dan setelah kegiatan. Pemahaman keekonomian penggunaan PLTS dan Lacuda ini diharapkan berguna untuk para nelayan. Selain bisa menjadi pendorong penggunaan PLTS dan Lacuda sebagai sumber energi listrik pada kapal nelayan juga secara tidak langsung mendukung kebijakan pemerintah dalam Blue Economy.

Abstract

The use of fossil energy as a source of fuel to turn on generators on fishing boats has long been used to assist fishing activities in Tablolong Village. The availability and lack of good use of this energy continuously will certainly be very bad for the sustainability of the fishermen's economy and the environment. The utilization of solar energy which has such great potential in East Nusa Tenggara can be one solution. The use of this technology is in line with the Blue Economy policy by the Ministry of Marine Affairs and Fisheries Republic of Indonesia. This 80 Wp PV system is installed on a 3 GT ship, then the energy that can be generated is analyzed and the Wilcoxon test is carried out to determine the fishermen's response to the use of the PV System. The utilization of the PV System as a source of electrical energy on 3GT vessels in Tablolong Village can meet the electrical energy needs of fishing boats. The electrical energy generated can meet 189% of the ship's electricity needs of 320 Wh/day with energy that can be produced by PV of 604.04 Wh/day. This result is also supported by the Wilcoxon test of the energy produced by PV for the ship's electrical energy needs. Based on the assessment indicators that have been carried out from before and after PV installation activities on fishing boats, it was found that there was a significant difference in the electrical energy needs before and after using PV System with a significant value of 0.001 (p < 0.05).

Abstract

The limited stock and uncertainty of fuel prices as a source of driving the main engine and generator on ships greatly affect the lives of fishermen in Indonesia. Even though there is a policy in the form of assistance from the government in the form of subsidies, fishermen still feel doubtful about being able to get such assistance. To overcome this and with the potential of solar energy in Indonesia, as well as a manifestation of appropriate technology and blue economy policies, a photovoltaic system is made that is combined with underwater lights as a fishing tool. Activities are carried out by measuring environmental conditions and the energy that comes out of the PV system and giving questionnaires to the fishermen. The results showed that the use of PV systems combined with underwater lights in fishing activities gave good results. The result of electrical energy that can be generated is 393.24 Wh/day and can meet the ship’s electricity needs for 4 days. This result is also supported by the Wilcoxon test results for technical, economic, environmental, health, and safety aspects with a significance value of 0.001 (p<0.05).

Abstract

The production of complex machine components requires advanced and accurate techniques. Achieving optimal quality through 3D printing involves carefully examining the process parameters. However, many studies have not thoroughly explored the impact of these parameters on parts produced using Fused Deposition Modeling (FDM) 3D printing. This study evaluates how process parameters and material variations affect the dimensional accuracy of printed parts. The study focuses on input variables such as material type, infill density, infill pattern, and raster angle. Using the fractional L9 Taguchi method, the optimal settings identified were PLA+ material, 80% infill density, an infill grid pattern, and a 0° raster angle, resulting in a 1.39%-dimensional deviation and an S/N ratio of -3.29 dB. ANOVA analysis reveals material type as the most significant factor, contributing 49.81% to performance. These findings, complemented by statistical analyses, can guide decision-making in industrial applications and serve as a reference for selecting FDM 3D printing settings related to dimensional accuracy to print components in the industry.
