Water is one of the natural resources that is needed for the life of living things. Almost all activities require clean water, both for the metabolism of living things, agriculture and industry and is a major need. So that the availability of clean water sources needs to be maintained and looking for new sources. One source of clean water is atmospheric air which is very abundant. By using a water generator from stable atmospheric air, where the air enters the PAWG system in which there is a thermoelectric which can form a temperature difference in order to convert water into water vapor which then becomes condensate. The PAWG performance tested here is the inlet air velocity with variations of 0.27 m/s, 0.52 m/s and 0.97 m/s. The results show that the inlet air velocity affects the volume of condensate water and the performance of the Psys and COP systems. The higher the air velocity, the greater the volume of condensate water generated and the higher the Psys. But the results are different for COP, where the highest COP occurs at an inlet air speed of 0.52 m/s followed by a speed of 0.27 m/s and the smallest is 0.97 m/s.

The ultra-violet dryer integrated with the biomass furnace is a drying method with a forced mechanism. In this study, an experimental study was carried out. The drying process of porang tubers uses a hybrid system ultra violet plastic dryer (UV solar dryer) through varying the speed of the inlet air to obtain efficient drying results and porang tuber products. The results showed that the final moisture content of porang tubers after drying per day for each variation of air speed obtained the lowest value of 10.50%bb with the highest drying rate of 0.3373 kg/hour from the assumption of an initial moisture content of 70%bb, which occurs in variations airspeed of 1.8 m/s. while the speed is 1.3 m/s with the lowest drying rate of 0.330 kg/hour with a final moisture content of 11.74%.bb) Drying efficiency for variations in the speed of hot air flow into the hot air duct of the biomass furnace shows the highest value at a speed of 1.3 m/s of 16.76% with the lowest specific energy consumption (KES) of 51975.7 kJ/kg.

Abstract This activity is intended to provide understanding and skills to the community in Lasiana Subdistrict, at Kupang City, on how to use house yard land to provide added value for family needs. This activity focuses on two types of plants, ginger and turmeric. How to grow a good ginger and turmeric, and maintain it. Giving added value to these two types of plants by processing them into ready-to-eat (instant) ginger and turmeric. The method used in this activity is interactive lectures and training (practice). Entrepreneurship and marketing of home industry products is also provided as additional knowledge. The participants are able to have skills in processing ginger and turmeric, into instant ginger and turmeric, which can be seen by their ability to make these products. The interest and knowledge of the participants in entrepreneurship must be followed up on the next activity. Keywords: ginger, turmeric, home yard use, added value, home industry Abstrak Kegiatan ini dimaksudkan untuk memberi pemahaman dan juga memberi ketrampilan pada masyarakat Kelurahan Lasiana di Kota Kupang, tentang bagaimana memanfaatkan lahan pekarangan untuk memberi nilai tambah bagi pemenuhan kebutuhan keluarga. Pada Kegiatan ini lebih di fokuskan pada dua jenis tanaman yaitu jahe dan kunyit. Bagaimana cara menanam jahe dan kunyit yang baik, dan memeliharanya. Pemberian nilai tambah pada kedua jenis tanaman ini, dengan mengolahnya menjadi jahe dan kunyit instan siap saji. Metode yang digunakan dalam kegiatan ini adalah ceramah interaktif dan pelatihan (praktek) pembuatannya. Tambahan pengetahuan mengenai kewirausahaan dan pemasaran produk industri rumah tangga, juga diberikan sebagai materi tambahan dalam kegiatan ini. Peserta kegiatan mampu menguasai dengan baik ketrampilan dalam mengolah jahe dan kunyit, menjadi jahe dan kunyit instan. Hal ini terlihat dengan mampunya mereka dalam membuat produk ini. Ketertarikan dan pengetahuan peserta kegiatan ini pada kewirausahaan merupakan suatu yang mengembirakan dan harus ditindaklanjuti pada kegiatan berikutnya.
