Abstract

Abstrak Perhitungan beban kalor perlu dilaksanakan terlebih dahulu sebelum dilakukan perencanaan sistem pengkondisian udara di suatu ruangan. Hal ini diperlukan karena besarnya beban kalor sangat berpengaruh terhadap kapasitas pendinginan yang dibutuhkan, sehingga kenyamanan dapat diperoleh. Salah satu ruangan yang menggunakan AC adalah ruang Kepegawaian Rektorat Undana. Kapasitas AC yang terpasang adalah 16 PK. Berdasarkan rekening listrik bulanan di gedung Rektorat Undana, biaya pemakaian listrik berkisar sekitar Rp.801.301.531.- per tahun atau sekitar Rp.66.775.128.- per bulannya. Sehingga perlu dilakukan pengamatan kembali terhadap Intensitas Konsumsi Energi (IKE) listrik dari AC apakah masih hemat atau tidak. Berdasarkan hasil penelitian, beban kalor pada ruang tersebut berkisar antara 175.491,3685 Btu/h sampai dengan 306.961,6477 Btu/h. Namun kondisi yang terjadi didapati ada jendela yang terbuka akibatntya infiltrasi beban kalor pada ruang tersebut besar, sehingga membuat 16 PK AC yang terpasang menyerap arus listrik yang besar akibatnya IKE dari 16 PK sebesar 31,06 kWh/m2/bulan, tergolong sangat boros. Apabila tidak ada jendela yang terbuka maka beban kalor puncak yang seharusnya terjadi adalah 125.434,6370 Btu/h, sehingga AC yang seharusnya beroperasi adalah 14 PK. Nilai IKE dari 14 PK adalah 6,63 kWh/m2/bulan tergolong dalam kriteria sangat efisien.

Abstract

ABSTRAK Pemberian vaksin adalah salah satu cara untuk mencegah penyakit pada hewan ternak sebagai anti body. Vaksin ini sangat rentan karena tidak boleh terkena sinar matahari secara langsung dan tidak boleh dibekukan. Untuk beberapa jenis vaksin harus disimpan pada temperatur 2oC - 8oC. Kendala terberat ketika harus membawa vaksin ke daerah-daerah terpencil yang sulit dijangkau dan tidak memiliki infrastruktur utama seperti jalan yang memadai. Perencanaan tabung pendingin ini memiliki dimensi tabung yang digunakan berukuran 3’’ dan 4’’. Tinggi tabung 3’’ adalah 14,6 cm dan tinggi tabung 4’’ adalah 19,8 cm berbahan dasar polyvinyl chloride. Hasil perencanaan diperoleh tegangan tarik yang terjadi pada selubung tabung pendingin 38,144 kg/. Tegangan tarik pada selubung ruang isolator 68,766 kg/. Tegagan geser penutup ruang pendingin 0,00093 kg/. Tegangan geser pada penutup tabung kg/. Tegangan tekan yang terjadi untuk logam las 8,656 kg/. Tegangan tarik ijin baut 74 N/mm2. Tegangan geser ijin baut 44,4 N/mm2. Diameter baut yang dibutuhkan 0,278 mm.

Abstract

ABSTRACT A reality for today's business world, that many small and medium industries and households are trying to build themselves to meet the growing need for fish feed. Based on this, it is appropriate that the production equipment owned must be optimized to support the effectiveness and efficiency of the fish feed production process. The VDI 2221 method uses a systematic approach to design for engineering systems and engineering products. This VDI 2221 method makes it easier for designers to make a product so that product design can be achieved. The author has a design to make a fish feed printing machine in the hope that it can be used as an alternative to produce products faster and more efficiently. The results of the design using the VDI 2221 method of fish feed printing machine are, using a motor power of 1 HP = 750 watts with a tool capacity of 42 kg/hour. Keywords: design, VDI 2221 method, feed printing device.

Abstract

An in-depth study is needed on the use of alternative energy to overcome human energy needs. This study aims to analyze the potential of ocean wave energy that can be converted by the "Oscillating Water Column" device on the Kolbano coast as a renewable energy source. Kolbano Beach is located in Kolbano Village, Kolbano District, and TTS Regency (South Central Timor) East Nusa Tenggara Province with an area of​approximately 17 sq km stretch of Kolbano beach area facing the Indian Ocean so that the consistency of the wave height produced is quite large. The wave height is large enough to be used as an alternative power plant. This research was conducted in Kolbano coastal waters, data on wave height and wind speed from BMKG (Metrology, Climatology, and Geophysics Agency) Kupang City in 2019 – 2021m with wave heights ranging from 0.31 to 2.3 m and wind speeds ranging from 1 .05 to 8.48 Watts.

Abstract

Desalination is the process of distilling seawater using a heat source from solar energy to obtain fresh water. Therefore, one of the methods used to increase the results of the seawater desalination process is to make a tool using solar energy and charcoal material. This research was conducted to determine the effect of using charcoal material on the seawater desalination process. The use of charcoal material is expected to increase the absorption of heat energy and accelerate the evaporation process of seawater. In this study, the highest efficiency was obtained in basin I with a mass of 500 grams of charcoal, namely 5.393% with 70 ml of water produced, followed by basin IV without using charcoal material with an efficiency of 6.116% with fresh water produced of 60 ml, followed by basin IV. II with a mass of 400 grams of charcoal obtained an efficiency of 1.585% with 59 ml of water produced. And in basin III the efficiency and fresh water produced is less, namely 0.004% and the water produced is 41 ml

Abstract

Solar desalination is the process of reducing brine salinity by using heat from the sun to produce fresh water. Distillation is one of the traditional solar desalination methods, but it has a low evaporation rate. Recently, interfacial solar evaporation by thermal localization at the liquid interface has been proposed as a promising alternative to evaporation. In this study, briquettes were investigated as as the interface solar absorber to increase vapor production. Experiments were carried out in 4 single-slope type distillers for 8 hours under clear sunlight using 10, 15 and 20 mm thick briquettes. For comparison, we also looked at distiller (basin) with no charcoal. Temperatures and humidity were measured at several position within the basin to identify factors contributing to seawater evaporation. We found that the vapor production increases when temperature is high and humidity is low. While condensation is highly dependent on humidity, high humidity is able to make water vapor molecule reach its dew point faster. This condensation process will greatly impact the productivity of the distillate.

Abstract

Abstrak Pemeliharaan ternak babi oleh sebagian masyarakat Kota Kupang adalah kegiatan usaha petemakan yang merupakan bentuk kegiatan komplementer dalam rumah tangga. Banyak warga yang memilih memelihara ternak, khususnya ternak babi ditengah pemukiman masyarakat, yang membuat warga sekitar mengeluh soal bau kotoran ternak. Kotoran ternak babi yang tidak ditangani merupakan masalah yang mengganggu  masyarakat karena pencemaran lingkungan yang ditimbulkannya. Untuk mengatasi masalah tersebut, kotoran ternak babi yang ada bisa diolah dalam sebuah unit digester untuk menghasilkan biogas. Selain itu, kotoran ternak babi yang telah diolah tidak akan menimbulkan bau yang mengganggu, dan menjadi pupuk dengan kualitas tinggi. Program pengabdian kali ini diharapkan dapat menyelesaikan masalah yang dihadapi mitra yaitu penanganan kotoran ternak babi. Disisi lain dengan membuat biogas dari kotoran ternak, juga dapat membantu perekonomian masyarakat. Gas yang dihasilkan dapat dijadikan bahan bakar pengganti minyak tanah maupun gas elpiji yang semakin langka dan mahal di pasaran, sehingga masyarakat akan lebih berhemat. Kata kunci: kotoran ternak; biogas; energialternatif. Abstract The rearing of pigs by some residents of Kupang City is a livestock business activity which is a form of complementary activity in the household. Many residents choose to keep livestock, especially pigs in the middle of residential areas, which causes local residents to complain about the smell of livestock manure. Untreated pig waste is a problem that disrupts people's lives because of the environmental pollution. The solution of this problem, existing pig manure can be processed in a digester unit to produce biogas. Apart from that, processed pig manure will not cause odorspolution and becomes high quality fertilizer. This service program is expected to be able to solve the problems faced by partners, namely handling pig manure. On the other hand, making biogas from livestock manure can also help the community's economy. The gas produced can be used as fuel to replace kerosene or LPG gas which are increasingly rare and expensive on the market, so that people will save more. Keywords: animal manure; biogas; alternative energy.
