Abstract

In connection with the easing of the Covid 19 virus in Indonesia, the Indonesian Christian University (UKI) Engineering PKM TEAM conducted welding training offline for children with special needs. The purpose of the Service for children at the Panti Karya is to be able to provide training in welding and making trash cans easily and effectively as life skills for the children of the HEPHATA HKBP Panti Karya Foundation in North Sumatra Participants, to be able to implement cleanliness around the Hephata HKBP Panti Karya Foundation in North Sumatra as well as children who already have the skills to make trash cans from welding training can generate incoming funds for the HKBP Hephata Panti Foundation in North Sumatra. With this dedication, we can equip the children of the Karya Orphanage with life skills in making trash cans and welding to increase their competence.

Abstract

Indonesia adalah negara yang memiliki potensi sumber energi terbarukan yang cukup besar, salah satunya adalah sumber energi angin yang potensinya mencapai 100 MW. Namun, pemanfaatan sumber energi angin di Indonesia masih belum maksimal, yakni baru sekitar 1.6% atau sekitar 1.6 MW. Desain turbin angin dan pengukuran kecepatan angin rata-rata merupakan hal yang penting dalam pemanfaatan potensi energi angin. Oleh sebab itu, dibutuhkan pengetahuan perihal desain dan simulai dari beberapa parameter yang mempengaruhi pemanfaatan energi angin, seperti jenis airfoil , kecepatan angin, pitch angle turbin angin, dan parameter desain turbin angin. Dalam penelitian ini, akan dilakukan desain sekaligus simulasi turbin angin menggunakan software Qblade dengan beberapa tipe airfoil yang berbeda, untuk mengetahui tipe airfoil  dengan bentuk geometrinya yang paling efisien dalam membangkitkan daya pada turbin angin.

Abstract

In the campus environment, the management of organic waste such as leaves is of particular concern, so a 2 HP organic waste shredder was designed with a rotation speed of 1450 rpm, a 150 mm diameter pulley, and a 6200 mm long shaft with 21 blades 15 mm thick, 25 mm wide, 100 mm long, and 24 mm diameter motor shaft made of S45C steel, supported by a 1.47 kW motor; Testing of this machine at various waste loads shows optimal results with different electrical power and engine rotation, such as at loads of 0.2 kg (237.8 V, 6.27 A, 1.49 kW), 3.5 kg (184 .1 V, 5.97 A, 1.15 kW , 1493 rpm), 5 kg (221.2 V, 6.37 A, 1,409 kW, 1990 rpm), and 8 kg (234.6 V, 6.38 A, 1,496 kW), so that this machine is supported by an on-grid PLTS with a power of 1740 WP which is able to increase the efficiency of electricity costs for the needs of operating the chopping machine. Keywords: 2HP AC motor; organic chopping machine
