Industri garam di Provinsi Nusa Tenggara Timur masih menggunakan cara manual dalam proses pencampuran garam dengan yodium yaitu dengan cara mengaduk bolak-balik setumpuk garam yang telah disemprotkan larutan iodat dalam garam dengan konsentrasi tertentu. Pencampuran seperti ini sangat tidak praktis, efisien dan efektif. Dari permasalahan tersebut perlu dilakukanya Rancang Bangun Mesin Mixer Iodisasi Garam Halus Sistem Injeksi Skala Home Industri Dengan Metode VDI 2222 yang bertujuan untuk membantu proses iodisasi garam di Provinsi Nusa Tenggara Timur sehingga produksi garam konsumsi sesuai standar SNI 3556. Dari hasil perancangan menghasilkan mesin mixer iodisasi garam dengan wadah berbahan stainless steel berkapasitas 25 kg, pengaduk tipe dayung dengan putaran 60,76 rpm yang digerakan oleh motor listrik 0,5 HP 1400 rpm dengan menggunakan transmisi kombinasi puli dan sabuk untuk memperkecil putaran. Sistem penyemprotan menggunakan sistem injeksi dengan tekanan berasal dari pompa DC 12 V dengan kecepatan aliran nozzle , kecepatan aliran dan daya pompa 36 watt. Hasil pengujian kandungan yodium pada garam krosok sebelum proses iodisasi adalah 0 ppm, kemudian dilakukanya proses iodisasi dengan perbandingan komposisi pencapuran 25kg garam krosok, 1,25g kio3 dan 25ml air dan lama waktu pengadukan pada pengujian 1 = 3 menit, pengujian 2 = 4 menit dan pengujian 3 = 5menit. Dan setelah dilakukanya proses pengadukan sehingga menghasilkan garam dengan kandungan yodium pada pengujian 1= 55,65 ppm, pengujian 2 = 53,83 ppm dan pada pengujian 3 = 49.16ppm. Dengan adanya alat ini nantinya diharapkan dapat meningkatkan kualitas prokduksi garam di NTT.
Abstrak Pohon Marungga merupakan salah satu tumbuhan yang memiliki manfaat yang besar. Untuk daunnya sendiri dapat dijakdikan menjadi suplemen gizi dan juga sebagai bahan dasar kosmetik. Daun Marungga sendiri dapat dijadikan bubuk untuk selanjutnya diproses ke dalam berbagai kebutuhan. Sebelum dijadikan bubuk, sebelumnya daun tersebut harus dikeringkan. Pengeringan manual selama ini membutuhkan waktu yang panjang dan tidak higienis. Pada penelitian ini diperoleh hasil, proses pengeringan selama 19 jam diperolehhasil penurunan kelembaban tidak bisa dilakukan secara cepat. Hal ini disebabkan karena temperatur dalam ruangan tidak mampu memanaskan udara sekitar dengan cepat sehingga proses pengeringan cenderung lebih lambat. Dengan beban pengeringan 20 kg daun Marungga mentah, diperoleh sekitar 3 kg daun kering.Kata kunci: marungga; perpindahan panas; lemari Abstract Marungga tree is one of the plants that have great benefits. The leaves themselves can be transformed into nutritional supplements and also as a cosmetic base ingredient. Marungga leaves themselves can be used as a powder for further processing into various needs. Before being made into powder, the leaf must be dried beforehand. Manual drying so far requires a long time and is not hygienic. In this study the results were obtained, the drying process for19 hours obtained the result of humidity reduction could not be done quickly. This is because the temperature in the room is not able to heat the surrounding air quickly so the drying process tends to be slower. With a drying load of 20 kg of raw Marungga leaves, about 3 kg of dried leaves are obtained.Keywords: marungga; heat transfer; cabinets
Most breeders generally feed their livestock only with grass, but for the grass itself it will be food that is easily found and is mostly given to livestock. However, most people still use machetes or sickles to cultivate grass, therefore SMEs have emerged in dealing with grass processing. The tool made is a grass chopper machine, the machine that was created also has several variations, one of which is a double knife chopper machine made by one of the students of the Nusa Cendana University Kupang, namely Stenly Naitboho. Therefore, this research was conducted to assess the performance of the chopper machine based on a feasibility study, in terms of the percentage length of the chopped material and the consumption of fuel used along with the production costs of this tool. In completing this research, several methods are needed to launch it, namely literature study and observation. After using the method used, the results of the chopping can be found, namely the percentage of the length of the chopped material measuring < 5 cm (W1) obtained an average of 54.62%, while the average percentage of the length of the chopped material measuring > 5 cm (W2) is 45.28%. For the size of the good chopped results is 2-5 cm in accordance with SNI 7785.1:2003 concerning the requirements for the results of the forage chopping machine. Another result in this study is the consumption of fuel used during the census obtained an average of 0.6 /hour. Based on SNI 7580:2013 the requirements for chopper work for fuel consumption of this machine are in category A. Production costs are obtained at a price of Rp. 4,122,200/ unit.

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.
