Abstrak— Penggerak perahu nelayan secara umum menggunakan mesin tempel yang menggunakan energi fosil (bahan bakar minyak bumi/BBM). Penggunaan BBM semakin banyak, dapat menyebabkan polusi udara. Sejalan dengan ini pemerintah juga mencanangkan hemat BBM dan BBM sudah tidak ada subsidi lagi. Hal ini menyebabkan biaya operasional bagi pengguna mesin tempel perahu nelayan semakin besar. Selain itu mesin perahu nelayan dengan menggunakan BBM dapat menimbulkan suara bising yang merambat ke dalam air laut, sehingga ikan bergerak menjauhi perahu. Hal ini menjadi kendala yang harus dipecahkan. Kendala-kendala ini dapat diantisipasi dengan mengganti mesin tersebut dengan mesin DC. Mesin DC sebagai penggerak perahu menggunakan listrik DC yang di suplai menggunakan baterao sehingga tidak menimbulkan suara bising dan tidak membuat ikan menjauh dari perahu nelayan. Pada penelitian ini akan diterapkan juga sumber listrik ramah lingkungan menggunakan tenaga matahari untuk sumber listrik pengisian baterai motor  sehingga penggunaan perahu nelayan dapat lebih lama dan nelayan tidak perlu khawatir kehabisan daya listrik selama panel surya mendapat paparan energy matahari. Perahu nelayan dengan penggerak motor listrik nantinya akan dilengkapi beberapa komponen antara lain 2 buah solar cell 100 WP, 1 buah baterai 100 Ah, dan motor listrik daya 500 watt.Kata kunci: Surya, Motor DC, Energi Terbarukan, Perahu Nelayan.Abstract— The driver of a fishing boat generally uses an outboard engine that uses fossil energy (petroleum / fuel). Increasing use of fuel, can cause air pollution. In line with this, the government has also planned to save fuel and fuel no more subsidies. This causes the operational costs for users of fishing boat outboard engines to increase. In addition, the fishing boat engine using fuel can cause noise that propagates into the sea water, so the fish moves away from the boat. This is an obstacle that must be solved. These obstacles can be anticipated by replacing the engine with a DC engine. The DC engine as a boat driver uses DC electricity which is supplied using batteries so it does not cause noise and does not keep the fish away from the fishing boat. In this research, environmentally friendly electricity sources will also be used using solar energy for motorbike charging, so that the use of fishing boats can be longer and fishermen do not have to worry about running out of electricity as long as solar panels get sun exposure. A fishing boat with an electric motor drive will be equipped with several components including 2 100 WP solar cells, 1 100 Ah battery, and a 500 watt electric motor.Keywords: Solar, DC motors, renewable energy, fishing boats.

Nowadays, almost 70-80% of industrial applications have used induction motors as the main driving component of the production process. induction motor damage causes important problems for users, especially if used in industries that can cause production process to stop [1-2]. Based on surveys conducted by Electric Power Research Institute (EPRI) on 6312 motors and IEEE-IAS Motor Reability Working Group on 1.141 motors almost 41-44% induction motor damage occurs in the bearing [3-5]. Bearing damage based on location can be categorized as outer race bearing damage and inner race bearing damage. Bearing damage causes vibration, noise, increase in operating temperature, can even cause sparks due to friction between motor components that cause damage to other parts of the induction motor. [5]. Studies of bearing damage have been carried out by several previous researchers such as detecting bearing damage based on vibration analysis in [6], although this method is quite effective, analysis will get different results based on the location of sensor so it is difficult to determine the position of sensor. Paper [7], also conducted a bearing damage detection study using noise but in practice it did not show accurate results because there were other disturbing noise around. Paper [8] analyze magnetic flux from induction motors that contain a lot of harmonics. Observation through magnetic flux can produce very accurate results in monitoring motor conditions, this can be seen in the harmonic spectrum, but this method is not practical because it requires the installation of coils at the stator core, so that the motor operation must be stopped, and the small air gap also makes this method difficult to implement. Monitoring using a stator current analysis has also been carried out on [8-10], analysis on the stator current successfully performed detection analysis on rotor bar damage, airgap,

Abstrak - Perahu merupakan salah satu armada yang digunakan para nelayan untuk mencari mata pencaharian. Namun pada umumnya pada saat perahu nelayan beropesi mengandalkan bahan bakar sebagai penggerak kapal, hal ini sangatlah tidak menguntungkan mengingat harga bahan bakar semakin mahal. Pada penelitian ini akan membahas desain dan perhitungan daya listrik penggerak perahu nelayan dimana enegi listrik didapat dari energi surya. Dengan adanya sistem pemanfaatan energi surya ini akan menghemat pengeluaran nelayan bahkan bisa dikatakan bahwa energi ini merupakan energi cuma-cuma atau gratis. Pada penelitian ini akan dihitung desain bodi perahu dengan kapasitas 2-3 orang, perhitungan kebutuhan alat penggerak, perhitungan kebutuhan energi listrik dan perhitungan panel surya yang akan digunakan. Hasil dari penelelitian ini dapat dijadikan kajian untuk pengembangan perahu ramah lingkungan, ekonomis, dan pemanfatan enegi surya yang merupakan energi terbarukan. Kapal yang dirancang mempunyai dimensi 3 meter dan lebar 1,33 meter dengan kecepatan 3-4 knot dan menggunakan panel surya dengan spesifikasi 150Wp sebanyak 3 buah.Kata kunci: perahu nelayan, energi penggerak kapal, panel surya, energi terbarukan, MPPTAbstract—Boat is one of the fleets that fishermen use livelihoods. But in general, when fishing boats oppose relying on fuel as a boat propeller, this is very unprofitable given the increasingly expensive. In this study will discuss the design and calculation of electric power driving a fishing boat where the electric energy is obtained from solar energy. Solar energy system will save fishermen's expenses. It can even be said that this energy is free energy. In this study the boat body design will be design with a capacity of 2-3 people, calculation of propulsion requirements, calculation of electrical energy requirements and calculation of solar panels to be used. The results of this research can be used as a study for the development of environmentally friendly, economical boats and the utilization of solar energy which is renewable energy. The ship was designed to have dimensions of 3 meters and 1.33 meters wide with a speed of 3-4 knots and uses 3 solar panels with capasity 150Wp.Keywords: fishing boat, boat propulsion energy, solar panel, renewable energy, MPPT
