"Pemanfaatan energi angin saat ini cukup meningkat sebagai energi terbarukan. Karena angin adalah salah satu bentuk energi alami yang paling mudah diakses dan tidak menghasilkan zat-zat berbahaya. Berdasarkan hasil pemetaan distribusi kecepatan angin, didapat kecepatan angin yang tinggi (6 - 8 m/s) di onshore terjadi di pesisir selatan pulau Jawa, Sulawesi Selatan, Maluku, dan NTT. Sementara kecepatan angin di daerah offshore menunjukkan angka lebih dari 8 m/s terjadi di Offshore Banten, offshore Sukabumi, offshore Kupang.[15] Turbin Angin sumbu vertikal (TASV) merupakan salah satu jenis turbin angin yang lebih mudah diaplikasikan pada tempat yang memiliki potensi angin tidak terlalu besar. [16] Tujuan dari penelitian ini adalah untuk membuktikan potensi TASV pada kabupaten Sukabumi.

The utilization of wind energy as a renewable energy source has been increasing recently. This is because wind is one of the most easily accessible natural energy forms and does not produce harmful substances. Based on the results of wind speed distribution mapping, high wind speeds (6 - 8 m/s) onshore occur on the south coast of Java Island, South Sulawesi, Maluku, and NTT. Meanwhile, wind speeds in offshore areas show figures of more than 8 m/s occurring in Offshore Banten, Offshore Sukabumi, and Offshore Kupang[15]. Vertical axis wind turbines (VAWTs) are one type of wind turbine that is easier to apply in places with relatively low wind potential.[16] The purpose of this research is to prove the potential of VAWTs in Sukabumi Regency."

"Alternative energy, nowadays, becomes more necessary than fossil fuels which might be destructing and polluting the earth’s environment. Wind can be one of the most cheap, secure, environment friendly and reliable energy supplies. Building Integrated Wind Turbine (BIWT) is becoming increasingly common as a green building icon and new method of assessing optimal building energy. However, to employ BIWT, it is important to design the building shape and swept area carefully to increase wind velocity. Some of numerous design forms of BIWT will be explained in this paper using CFD (Computational Fluid Dynamics) analysis to find the most effective BIWT design in urban area. This paper will focus on the maximum wind velocity which passes the swept area to get maximum wind power. The result shows that, building energy can be optimized through aerodynamic building design to get the maximum wind power for building energy consumption."

"Untuk mengurangi ketergantungan yang sangat besar terhadap energi fosil-yang mencapai 95% (Pusdating, KESDM, 2012) perlu pemanfaatan energi yang berasal dari bahan bakar bukan fosil. Pengembangan energi alternatif juga mendukung realisasi tujuan pembangunan berkelanjutan dalam menyediakan energi baru dan terbarukan mengacu kepada PP No. 2 Tahun 2017 tentang Rencana Umum Energi Nasional/RUEN Indonesia memiliki potensi yang besar dalam pengembangan energi gelombang laut sekitar 17.989 MW dengan kapasitas terpasang sebesar 0,3 MW (0.002%) dan energi angin sekitar 60.647 MW (> 4 m/s) dengan kapasitas terpasang 3,1 MW (0,01%). Penggunaan energi terbarukan sebagai sumber listrik menjadi solusi untuk mengurangi penggunaan bahan bakar fosil. Namun energi baru terbarukan ini memiliki kekurangan dikarenakan bergantung pada kondisi alam, maka energi yang diberikan tidak dapat ditebak menyebabkan energi yang dikeluarkan tidak stabil dan memungkinkan tidak ada ketika diperlukan. Makalah ini bertujuan untuk mengetahui kemampuan gelombang laut menjadi solusi lain untuk PLTB dalam menghasilkan energi listrik, dikarenakan energi angin memiliki potensi ketiga terbesar setelah Surya dan Hydro tapi kapasitas terpasang dan pemanfaatanya masih sangat minim.

To reduce the huge dependence on fossil energy-which reaches 95% (Pusdating, KESDM, 2012) it is necessary to utilize energy derived from non-fossil fuels. The development of alternative energy also supports the realization of the sustainable development goals in providing new and renewable energy referring to PP No. 2 of 2017 concerning the National Energy General Plan / RUEN Indonesia has great potential in the development of marine wave energy of around 17,989 MW with an installed capacity of 0.3 MW (0.002%) and wind energy of around 60,647 MW (> 4 m / s) with an installed capacity of 3.1 MW (0.01%). The use of renewable energy as a source of electricity is a solution to reduce the use of fossil fuels. However, this new renewable energy has its drawbacks because it depends on natural conditions, the energy provided cannot be guessed causing the energy released to be unstable and allows it to be absent when needed. This paper aims to determine the ability of ocean waves to be another solution for PLTB in producing electrical energy, because wind energy has the third largest potential after Solar and Hydro but its installed capacity and utilization are still very minimal."

"Salah satu upaya untuk mengatasi krisis energi adalah mengurangi ketergantungan terhadap sumber energi fosil dengan cara memanfaatkan sumber energi alternatif. Salah satu energi alternatif yang dapat digunakan adalah energi angin. Energi angin dapat dimanfaatkan pada pembangkit listrik tenaga angin. Pembangkit listrik tenaga angin merupakan suatu metode untuk membangkitkan energi listrik dengan cara memutar turbin angin yang dihubungkan ke generator, kemudian energi listrik yang dihasilkan oleh generator disimpan dalam elemen penyimpan energi listrik (baterai). Energi listrik yang tersimpan dalam elemen penyimpan akan dibebankan kepada beban beban rumah tangga yang berdaya rendah sehingga dengan pembangkit ini akan terlihat penggunaan sistem pembangkit listrik tenaga angin ini dengan turbin angin berporos vertikal tipe savonius.

One effort to overcome the energy crisis is to reduce dependence on fossil energy sources by utilizing alternative energy sources. One of the alternative energy that can be used is wind energy. Wind energy can be utilized in wind power. Wind power is a method for generating electrical energy by rotating wind turbines connected to generators, and electrical energy generated by the generator is stored in the elements of electrical energy storage (batteries). Electrical energy stored in the storage element will be charged to expense burden of households with low power so that this generation will be seen savings on residential electricity costs. "

Demand for energy from renewable sources continues to drive the need for wind power

plants in Indonesia. The purpose of the study is to describe modeling decision making for wind

turbine locations and to design wind turbine technology that is well used in Indonesia. This

study uses the Multi-Criteria Decision Making method as a decision-making method that is

integrated with the Geographic Information System method as a location determination

method and suitable technology for building wind turbines. Furthermore, the results will be

used as initial design parameters for wind turbine technology. During the analysis process,

multivariate factors are considered. The area covered in this study is Indonesia.

The results of the study are in the form of a suitability map of the area with wind energy.

The match parameter is divided into four, namely "very suitable", "suitable", "less suitable",

and "not suitable". The results conclude that 40% of Indonesia's area falls into the "suitable"

category for wind energy, especially on the islands of Sulawesi and East Nusa Tenggara.

Meanwhile, 20% of Indonesia's area falls into the "unsuitable" category based on local

geographic conditions, despite high wind speeds, and is vulnerable to natural disasters.

Identification of this suitability area will be the initial consideration for the optimal wind

turbine technology design for Indonesia.

This modeling framework can encourage the renewable energy transition regardless of

special regions which are expected to contribute as much as 8% of the total target of achieving

Indonesia's 2025 renewable energy transition."
