Abstract

Nusa Tenggara Timur (NTT) terletak di sekitar daerah ekuator yang memiliki ketersediaan sinar Matahari sepanjang tahun dan potensi kelautan yang begitu besar. Sebagai salah satu daerah dengan kegiatan penangkapan ikan yang begitu besar tentunya akan membutuhkan energi listrik yang besar. Seiring dengan kebutuhan dan berbagai jenis kapal yang berkembang, kebutuhan tenaga listrik di atas kapal akan sangat beragam, khususnya pada kapal yang berukuran 5 GT. Sumber listrik di atas kapal selain menggunakan generator juga dapat memanfaatkan energi dari sinar matahari sebagai sumber energi listrik alternatif. Energi matahari dapat digunakan sebagai pengganti energi konvensional yang mulai terbatas dan harganya yang cukup mahal. Potensi energi surya di NTT sebesar 6,07 kWh/m2 tentunya dapat dimanfaatkan secara maksimal sebagai sebagai sumber energi listrik. Pemanfaatan energi surya sebagai energi listrik dapat dilakukan dengan menggunakan PLTS. Energi listrik yang dihasilkan dapat digunakan untuk menghidupkan peralaan listrik dan lampu kapal di malam hari, dan digunakan sebagai alat bantu penangkapan ikan. Dalam sehari sistem ini dapat menghasilkan energi sebanyak 0,53 kWh/hari. Sistem ini juga telah mudah diperoleh dan tersedia, baik di toko-toko konvenional atau online. Sehingga jika terdapat permasalahan dapat diatasi secara cepat. Penggunaan energi surya sebagai energi listrik tentunya diharapkan dapat meningkatkan kesehatan dan mengurangi pengunaan energi fosil yang kurang baik untuk lingkungan.

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 limited fossil energy and uncertain prices have an indirect effect on fishing activities using a fixed lift net. Therefore, energy diversification is carried out by utilizing solar energy with photovoltaics on the fixed lift net. This energy is very abundant and available throughout the year, except during the rainy season. This study uses observation, interviews, and questionnaires given to fishermen and tries to compare the utilization of photovoltaic (PV) systems with generators using different types of lamps, such as LED, CFL, incandescent lamps, and halogen lamps. The use of PV systems in fixed lift nets from a technical and economic perspective allows it to be utilized in the long term. Based on the technical aspects, the PV system can produce 471.59 Wh per day. This technical result will be more profitable if the lamp used is a light emitting diode (LED) lamp. Meanwhile, from economic aspect, the use of electrical energy from a PV system is more profitable because it provides a lower operational value than a generator, and provides good net present value (NPV) and internal rate of return (IRR) values. This utilization is also supported by the good response from fishermen towards the energy produced and the ease of operation and maintenance of the PV system.
