Abstract

ABSTRAKDesa Tubuhue merupakan salah satu daerah di Kecamatan Amanuban Barat, Kabupaten TTS. Desa Tubuhue berjarak ±96 KM dari Kota Kupang dan hanya dapat ditempuh dengan perjalanan darat dengan waktu tempuh ± 1,5 s/d 2,15 jam. Mayoritas masyarakatnya bermata pencaharian sebagai petani palawija dan peternak. Satu-satunya hasil pertanian andalan masyarakat desa Tubuhue diluar palawija adalah buah jagung, yang dipanen sekali dalam setahun pada bulan September. Pemahaman masyarakat akan potensi alam dan pola pikir yang hanya mengandalkan hasil alam yang telah ada/disediakan alam tanpa ada upaya pengembangan, menjadi penyebab utama keterpurukan ekonomi atau kemiskinan yang melanda hampir seluruh masyarakat Desa Tubuhue. didesa ini terdapat sumber mata air dan danau yang selalu menyediakan air meskipun pada musim kemarau. Namun sumber air yang terbilang maksimal ini tidak dimanfaatkan secara baik untuk kegiatan ekonomi produktif dan hanya semata-mata dimanfaatkan untuk kebutuhan MCK dan beberapa memanfaatkan untuk bertani sayur yang semata-mata untuk keperluan konsumsi. Limbah peternakan juga sama sekali tidak dimanfaatkan untuk sumber energi dan hanya sebagian yang dimanfaatkan sebagai kompos. Melalui program ini dapat memberikan pengetahuan dan pemahaman serta skill yang maksimal untuk dapat mengelola potensi yang dimiliki dengan pembuatan biogas dari kotoran ternak dalam meningkatan kesejahteraan hidup masyarakat di desa Tubuhue. Hasil dari program ini masyarakat mampu untuk memanfaatkan potensi limbah /kotoran ternak sebagai sumber energi terbarukan biogas. Kata kunci: biogas; desa tubuhue; kotoran ternak. ABSTRACTTubuhue Village is one of the areas in West Amanuban District, TTS Regency. The village of Tubuhue is ±96 KM from Kupang City and can only be reached by road with a travel time of ± 1.5 to 2.15 hours. The majority of the people make a living as secondary food farmers and ranchers. The only mainstay agricultural product for the people of Badanue village outside of palawija is corn, which is harvested once a year in September. The community's understanding of the potential of nature and a mindset that only relies on natural products that already exist by nature without any development efforts are the main causes of usage downturn or poverty that hit almost the entire community of Tubuhue Village. In this village, there are springs and lakes that always provide water even in the dry season. However, this maximum water source is not used properly for productive economic activities and is only used for toilet needs and some use it for vegetable farming which is solely for consumption purposes. Livestock waste is also not used as an energy source at all and only part of it is used as compost. Through this program, they can provide maximum knowledge and understanding as well as skills to be able to manage their potential by making biogas from livestock manure in improving the welfare of the community in the village of Tubuhue. The result of this program is that the community can take advantage of the potential of livestock waste as a renewable source of biogas energy. Keywords: biogas energy; tubuhue village; livestock waste

Abstract

The process of cooling and freezing carried out on fish products is one of the preservation methods that apply a cooling machine in its operation. The refrigeration machine used applies a steam compression refrigeration system with R404A refrigerant as its working fluid. A design that is not following the standards can result in significant losses both in material and economic terms. Besides, the wrong model can also cause the performance of the engine to cool down. The purpose of this study is to design and analyze the performance of cold storage for freezing fish using Coolselector®2 software version 3.6.1. Performance analysis is based on superheating and subcooling temperature variations to determine its effect on the performance of the cooling engine. Changes for superheat temperatures carried out at the 8K, 9K, 10K, 11K and 12K levels while the subcooling temperature is considered constant at the 3K level. Variations were made at subcooling temperatures at the 3K, 4K, 5K, 6K and 7K levels with superheat temperatures considered consistent at the 5K level. The result of cold storage room design shows that the room has a cooling capacity of 14.54 kW. Analysis of the performance of the engine coolant design shows that the refrigeration machine has excellent performance. It will be proved by the higher subcooling and superheat temperatures, the COP also increase. The most top COP is at the 12K superheat temperature level of 2.045, while for the subcooling temperature at the 7K level of 3.144

Abstract

The design of several vehicles by changing the design of the vehicle body and household materials using composites has already been carried out in Indonesia using various methods and using natural materials that are easy to find. A unique motorcycle body design can give an attractive impression from the appearance of the motorcycle in use, seen from the new physical conditions with the image of a motorcycle that is easily engineered in such a way that it becomes an opportunity for motorcycle manufacturers to design motorcycle bodies with natural materials that can received potential market share. One of the natural materials that can be made or designed to be used as an alternative to composite raw materials as motor designs that are easy to find in the NTT region is one of them is palm fiber, whose use is still limited.
