Abstract

Aquaponic is a combination hydroponic (cultivation of plants without soil) and aquaculture (fish growing) that promotes sustainable food production. In order to be adopted by general population, the design of aquaponics needs to be practical and economical. The main purpose of this community outreach is to design and introduce small-scale aquaponics system that can be used by homeowners with limited backyard. For this purpose, the community located at Kelapa Dua Tangerang was chosen as the main partner. The prototype of the small-scale aquaponics was then used as education and demonstration tool to encourage the community of Kelapa Dua Tangerang to adopt eco-friendly aquaponics cultivation system. The prototype of the aquaponics worked flawlessly with the water circulation inside the system was set at 0.046 litre/second. The water was used to supply adequate nutriens for water spinach, lettuce and pak choy which can be harvested in two months. In addition, this leafy greens can enhance the overall yard aesthetics. For the aquaculture, the catfish in the tank showed steady grow rate and healthy condition. In general, the education process can be considered successful as indicated by positive responses from the community (feedback score of 2.93 out of 4). From joint evaluation, the community excited with further development of the small-scale aquaponics.

Abstract

ABSTRAKPenelitian ini membahas penurunan torka cogging pada generator sinkron magnet permanen untuk untuk aplikasi pada pembangkit listrik tenaga angin. Untuk meminimalkan nilai torka cogging, dapat dilakukan berbagai teknik, salah satunya adalah kombinasi teknik pangkasan magnet dan alur tiruan pada inti jangkar. Teknik ini diterapkan terhadap generator sinkron magnet permanen tipe integral slot dengan jumlah gigi alur 30 dan kutub 10 dan tipe fractional slot number dengan jumlah gigi alur 24 dan kutub 10. Berdasarkan hasil analisis menggunakan metode elemen hingga, didapatkan bahwa tipe fractional slot number memiliki penurunan torka cogging sebesar 98.51 % dari torka berbebannya, sedangkan penurunan torka cogging pada generator tipe integral slot number sebesar 75 % dari torka berbeban.Kata kunci: Generator sinkron magnet permanen, torka cogging, fractional slot number, integral slot number, pangkasan magnet, alur tiruan ABSTRACTThis research discusses the reduction of cogging torque on a permanent magnet synchronous generator for applications in wind power plants. To minimize the value of the cogging torque, various techniques can be carried out, one of which is a combination of magnet trimming techniques and artificial grooves on the anchor core. This technique is applied to an integral slot type permanent magnet synchronous generator with 30 grooved teeth and 10 poles and a fractional slot number type with 24 grooved teeth and 10 poles. Based on the results of analysis using the finite element method, it was found that the fractional slot number type has a torque reduction. cogging of 98.51% of the loaded torque meanwhile the decrease in cogging torque on the integral slot number type generator is 75% of the loaded torque.Keywords: Permanent Magnet Synchronous Generator, cogging torque, fractional slot number, integral slot number, magnet shaping, artificial groove
