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.

The need for electrical energy continues to increase every time. Concerns about the depletion of fossil energy reserves encourage the acceleration of the development of renewable energy use. One of renewable energy is the solar energy. Due to the irreversible irradiation conditions, it takes controls to keep the solar panel's maximum power. The most widely in Maximum Power Point Tracking (MMPT) is Perturb Algorithm and Observe (P&O) but P&O Algorithm has deficiency of oscillations when steady state and MPP trace errors when irradiation changes rapidly. In this paper proposed P & O-Fuzzy algorithm is a modification of conventional P & O to improve the efficiency of solar panels. This research uses Matlab for simulation and hardware implementation using microcontroller Arduino Uno and buck converter topology. The result of simulation and hardware implementation, conventional P & O has an average efficiency of 85.03% while MPPT modification with P & O-Fuzzy algorithm can improve MPP tracking efficiency with 89.67%.

The Government

At this time the cost of electricity is very expensive which is felt by the community because the government is still exploring oil and natural gas which is the need for non-renewable energy sources that are running low. This non-renewable energy still dominates for power generation in the thousands of Mega Watts. To anticipate the problem of non-renewable energy that is so big, you can use the On Grid-Tie System, sunlight is converted into DC voltage through the Solar Module, a pure DC voltage that comes out of the solar module. And Off Grid-Tie System namely sunlight is converted into DC voltage through the Solar Module, pure DC voltage generated from the solar module. Then the pure DC voltage uses a DC to DC regulation module or is called a DC regulator. DC regulator which aims to regulate the storage of DC current into the battery. Then the battery is used to supply power to the inverter. The method used in this study uses an off-grid solar home system as a power supply for households that are far from the electricity network or save electricity consumption due to expensive electricity rates. For settings for the intensity of sunlight using a portable holder, the solar panels are shifted manually in order to get the optimal light intensity to produce large output power. In off-grid application testing at household loads, from a load test of 93.5 watts to 750 watts, it shows that the load current is getting bigger and the discharging current is also large so that the duration of using the off-grid system from a load of 93.5 watts is 6 hours long and at a load of 750 watts. up to 15 minutes. This is because the condition of the lead-acid battery is maintained from 13.56 to 11.5 Volt DC, the battery should not be forced below the 11.5 Volt voltage because it will cause damage to the battery. For the use of loads that respond to very high instantaneous currents such as electric irons, dispensers, rice cookers should use more batteries and use an off-grid system voltage higher than 12 Volt DC.

Electrical energy is a very important part of human activity at this time. At present a very popular source of renewable electricity is energy (solar) through the use of solar power generation system. "Design Passive Photovoltaic 50 Wp in Renewable Energy Laboratory State Polytechnic of Malang" aims to plan and analyze the solar power generation system (PLTS), namely a capacity of 50 wp,so that it can be used as a guideline when going to design or implement PLTS on a larger scale. Based on the analysis and testing carried out, namely testing of 50 Wp passive solar panels under normal (clean) angles of 0º, 15º, 30º and shading angles of 0º, as well as the fouling angle of 0º produces the highest energy of 210.7 Wh when the condition of the solar panels is at an angle of normal 30º.

<span lang="EN-US">A main source of current renewable energy is solar energy. This source of renewable energy can be converted to electrical energy using solar photovoltaic (PV) cells. The Maximum Power Point Tracking (MPPT) earns for maximum energy extractor from PV panels by different irradiance levels. In this paper, overall efficiency of most two popular MPPT techniques utilized in PV applications are analyzed, these  algorithms are Perturb and Observe (P&amp;O) and Incremental Conductance (INC). An analysis of the results for the algorithms based on MATLAB simulation for various changes in solar irradiance is performed. Results showed that the efficiency of P&amp;O algorithm was higher than that of the INC, but to obtain the same performance for both, more concentrated calculations should be used for INC. In measuring the output power, current and voltage responses, the use of a solar array having constant and variable irradiations was employed as input for the algorithms. The output waveforms which were derived from a simulation run for the purpose of obtaining the algorithms response to changes in solar array irradiations were compared. In general, the consequences of the P&amp;O algorithm are quiet good and adequate. However, there is a need to improve the algorithm so as to satisfy the requirements of face confident timing in addition to its rapid response so as to make its performance better than that of InCond algorithms.</span>

The potential of renewable energy in the province of North Sumatra has not given confidence to the provincial government to establish Energy Independent Village (EIV). This paper aims to describe the utilization of renewable energy in the village Buluh Awar who have had success using a water-based renewable energy as a source of electrical energy for 25 (twenty-five) years. The approach in this study is qualitative and uses data collection techniques such as observation and interview. The study was conducted in May 2016 and took place in the Buluh Awar village, Sibolangit sub-district, Deli Serdang District. The village was chosen because it has been using the power source coming from renewables for 25 (twenty-five) years, but has not been designated as EIV. The informants were: the user community; plant manager; headman; Department of Mines and Energy (Distamben) North Sumatra Province; and, Distamben Deli Serdang. Analysis of the factors that play a role in the utilization of renewable energy shows that the North Sumatra Province has the ability to form the EIV. Based on the analysis of the factors that play a role in the utilization of renewable energy, it can be concluded that the village Buluh Awar has the ability to set as DME, if followed by the intervention of the local government by providing technical assistance to improve generating capacity so that it can generate more electric power so that society can do creative activity that can push economic growth at Buluh Awar village.

The transmission of electric energy from renewable energy sources requires a system of transmission of electrical energy. The most widespread system of electric power transmission is AC and DC. The chapter presents a description of a resonant system of electric power transmission on one wire. This system converts AC or DC voltage and transmits it over a single wire. At the end of a transmission line is a reverse converter that generates the standard voltage. This system of transmission of electrical energy can be applied to lighting systems.
