Abstract

ABSTRAKKegiatan pengabdian ini mengambil tema tentang pembuatan eco enzyme dan pemanfaatannya bagi lingkungan sekitar rumah tangga. Kegiatan ini merupakan jawaban atas keprihatinan sebagian besar masyarakat yang ada di KUB Yomavi, di RT 021, RW 001 Kelurahan Bello, Kota Kupang, tentang penanganan sampah organik rumah tangga yang cukup melimpah dan terbuang sehingga menimbulkan bau busuk di lingkungan sekitar rumah. Dari kegiatan ini masyarakat bisa memanfaatkan sampah-sampah organik ini sekaligus menjaga kelestarian lingkungan hidup. Metode kegiatan terdiri dari ceramah, diskusi, tanya jawab, simulasi dan praktek. Pembuatan eco enzyme dalam pelatihan ini yaitu sebanyak 70 liter dan akan dipanen setelah difermentasi selama 3 bulan sesuai dengan aturan pembuatan eco enzyme. Di akhir kegiatan pengabdian, tim juga berhasil membagikan eco enyme kepada masyarakat, sehingga masyarakat dapat lebih lanjut memanfaatkannya di rumah masing-masing. Hasil lain yang lebih penting yaitu masyarakat semakin sadar tentang manfaat eco enzyme bagi kelestarian lingkungan hidup, dan juga mendapatkan pengetahuan dan keterampilan tentang cara pembuatan eco enzyme  dari sampah rumah tangga berupa sisa kulit buah dan sayuran. Dengan demikian masyarakat pun bisa secara mandiri membuat eco enzyme ini di rumahnya. Kata kunci: sampah organik; eco enzyme; lingkungan hidup. ABSTRACTThis service activity takes the theme of making eco enzymes and their use for the environment around the household. This activity is an answer to the concerns of most of the people in KUB Yomavi, in RT 021, RW 001, Bello Village, Kupang City, regarding the handling of household organic waste which is quite abundant and wasted, causing a foul odor in the environment around the house. From this activity, the community can take advantage of this organic waste while preserving the environment. The method of activity consists of lectures, discussions, questions and answers, simulations, and practice. The production of the eco enzyme in this training is 70 liters and will be harvested after being fermented for 3 months according to the rules for making eco enzyme at the end of the service activity, the team also succeeded in distributing eco enzyme to the community, so that the community could further use it in their respective homes.  The more important result is that people are increasingly aware of the benefits of eco enzymes for environmental sustainability, and also gain knowledge and skills on how to make eco enzymes from household waste in the form of leftover fruit and vegetable peels. Keywords: organic waste; eco-enzymes; environment.

Abstract

The objective of this research was to get the effect of friction pressure on the tensile strength of the joining of aluminum alloy AA6061 and carbon steel, with continuous drive friction welding process. Variations of friction pressure of this research were 24 MPa, 32 MPa, and 40 MPa. In this study, a friction time 9 seconds was used. Other friction welding variables were, forging pressure 79 MPa, forging time 60 seconds, and friction rotation speed 1600 rpm. The independent variable was the ultimate tensile strength of the welded joint. The results showed that the increase in the tensile strength of the joint was not linear with the increase of frictional pressure. The rate of the increase in the tensile strength of the connection, will decrease after the frictional pressure passes through 32 MPa. When the rate of increase in the tensile strength of the joint begins to decrease, the joint will become more brittle. The maximum tensile strength of the joint in this study was 167.421 MPa at a frictional pressure of 40 MPa.
