One of the biggest obstacles to development progress in Eastern Indonesia is the unavailability of electricity,especially on small island islands. The potential of ocean currents is one of the most renewable sources ofenergy considering that the majority of Eastern Indonesia is the ocean and has not been utilized optimally. Thepurpose of writing this paper is to reference the calculation of ocean currents for Indonesian coastal islands thathave minimal electricity. This research method uses literature studies on the morphology of the flow velocity andwind that occurs in the Capalulu Strait and the calculation of the potential of electrical energy in the CapaluluStrait so that the results of this calculation are used as one of the renewable energy methods that are able tomeet the electricity needs of island islands. which has not been electrified in Indonesia, especially in the SulaIslands, North Maluku.Keywords: Electric Energy, Ocean Flow Turbine, Renewable Energy, Strait of Capalulu

Energy has important meaning in social and economics achievement to continously development and support to national economics activities. Energy consumption in Indonesia increases rapidly parallel with economics engagement and people growth. To supply energy requirement, renewable energy source should be developed. Renewable energy potency like solar energy hasn’t been used for big scale although Indonesia has big energy potency. Indonesia be included on tropical area which is exposed sun radiance almost year. It means solar energy has good prospects to be developed in Indonesia. Solar energy is one kind of energy which is gotten by converting sun calor energy to another type of energy. Solar energy can be used in form solar cell for electrical power plant. The utilization of solar cell can help people who lives on isolated area which is far from electrical network to use electrical energy.

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

Ocean Thermal Energy

The ocean, which covers two-thirds of the land surface, receives heat from the sun's rays. Ocean water also receives heat that comes from geothermal heat, which is magma located under the seafloor. Ocean surface temperatures are warmest near the equator, with temperatures from 25°C to 33°C between 0 degrees and 20 degrees north and south latitude. This temperature difference can be utilized to run the driving machine based on the thermodynamic principle. A technology called Ocean Thermal Energy Conversion (OTEC) is capable of converting the temperature difference into electrical energy. OTEC is a power plant by utilizing the difference in the temperature of seawater on the surface and the temperature of deep seawater. This paper briefly overviews of how ocean heat can be utilized as a renewable energy source to produce electrical energy. The development and exploitation of renewable marine energy in the future are feasible and this will involve multidisciplinary fields such as robotics and informatics.

Accounting regulations approved through Order 1802/2014 makes remarks regarding the reflection of green certificates in accounting.      Green certificates are titles that attest the production of a quantity of electrical energy from renewable sources. These can be traded distinctly from the amount of electrical energy that they represent. A.N.R.E. (National Agency of Energy Regulation) rewards producers of renewable electricity to benefit the promotion of sustainable energy through green certificates. Electricity providers and some producers are required to purchase a number of green certificates on a quarterly basis. They are then required to transmit to the National Agency of Energy Regulation, in the specified format and by the deadline set by them, the quantities of electrical energy for which they need to purchase green certificates, in conformity with law 220/2008. The cost of green certificates is billed separately from the price of electric energy inaccounting tratament the invoice sent to the final customers. Providers or producers that do not meet the yearly quota must pay the value of green certificates not acquired in said timespan. According to the ministry’s of public finance Order 1802/2014, producers of renewable energy, that benefit from green certificates provided by the transport and system operator must register the green certificates received into their accountings using specific accounting accounts

Aceh Tamiang is the province o f Aceh. The use of electrical energy is still not resolved in this case because of the lack of appropriate policies that can be taken because there is still no research how the amount of electrical energy consumption in Aceh Tamiang. the research method used is a model based approach to End Use of data population and households, the data GDP at constant prices, and consumption of electrical energy. All data is sourced from related agencies such as Bappeda Aceh Tamiang Data PLN Kuala Simpang branch. Forecasting electric energy consumption in Aceh on five sectors is the year 2013 was 48.8 GWh, while, in 2030 total energy consumption reached 76.5 GWh, this is an increase of 63.7 percent. The household sector accounted for the largest increase in consumption compared with other sectors for each year.
