Abstract

STUDI LAJU EVAPORASI PADA DIRECT EVAPORATIVE COOLING BERBAHAN PAD JERAMI PADI DAN TAPIS KELAPA. Penggunaan sistim pendingin yang berbasis kompresor telah terbukti dapat menyebabkan peningkatan penggunaan energi bahan bakar fosil, dan juga dapat meningkatkan kerusakan lingkungan. Sistim pendingin evaporative banyak dikembangkan sebagai sistim pendingin alternative pengganti sistim pendingin berbasis kompresor. Dalam penelitian direct evaporative cooling ini akan dipelajari laju evaporasi yang terjadi pada cooling pad yang berbahan jerami padi dan tapis kelapa. Penelitian dilakukan dengan tiga variasi kecepatan putar fan 1440, 1470 dan 1500 rpm, dengan dua material pad yang berbeda jerami padi dan tapis kelapa, dan dengan waktu pengujian selama 60 menit dengan pencatatan data setiap selang 15 menit. Dari penelitian ditemukan bahwa laju evaporasi tertinggi terjadi pada kecepatan putar rendah 1440 rpm sebesar 0.00157 liter/menit dan 0.00293 liter/menit masing-masing untuk jerami padi dan tapis kelapa. Sebagai kesimpulan dapat dinyatakan bahwa tapis kelapa menghasilkan laju evaporasi yang lebih tinggi dibandingkan dengan jerami padi pada kecepatan putar rendah yang sama.

Abstract

Kemampuan kelompok nelayan tradisional di bidang kemampuan teknologi pengolahan ikan masih sangat rendah. Hal ini disebabkan kurangnya pengetahuan dan terbatasnya sarana-prasarana yang mendukung. Sehingga berdampak pada pendapatan nelayan menjadi tidak maksimal. Teknologi pengolahan ikan merupakan suatu metode untuk menjaga kondisi ikan agar bisa bertahan lama dan tidak mudah rusak. Dari beberapa teknologi yang ada, pada pelaksanaan pengabdian masyarakat ini bertujuan untuk meningkatkan pemberdayaan masyarakat nelayan tentang proses pengawetan ikan dengan menggunakan mesin pendingin. Mitra pengabdian yang dipilih adalah kelompok nelayan Amertha Segara yang berlokasi di Desa Bugbug, Kabupaten Karangasem. Metode pelaksanaan pengabdian masyarakat meliputi melakukan survey awal, melakukan evaluasi kemampuan masyarakat sebelum pelatihan, memberikan penyuluhan dan pelatihan pengawetan ikan menggunakan mesin pendingin, mengevaluasi pehaman masyarakat pasca pelatihan dan memberikan bimbingan teknis tentang pengoperasian dan perwatan mesin pendingin. Dari hasil yang diperoleh pada awalnya kemampuan masrakat nelayan tentang mekanisme pengawetan ikan menggunakan mesin pendingin masih sangat rendah, setelah adanya penyuluhan dan pelatihan pemahaman masyarakat menjadi meningkat, masyarakat mengikuti penyuluhan dan pelatihan sampai akhir dengan semangat.

Abstract

ABSTRACT Electroplating is a metal or non-metal coating process with electrolyze that use direct current (DC) and electrolyte (chemical solution) that has a function as medium to supply metal ions. The function of electroplating are protecting metal from corrotion attack, adding surface hardness and improving quality of metal surface. Electroplating process basically has four steps; cleaning, washing, coating and protecting. For a quality result, the coating process need a right and optimum condition of operation, such as, a right concentration of electrolyte, a right voltage or current, and a right temperature.

Abstract

Indonesia is an archipelago that is known as a maritime nation. Indonesia is rich in marine resources of fishery subsector. The majority of Indonesia's population are their livelihood as fishermen, especially in coastal areas. Bugbug village located in East Bali which is a coastal area that some community livelihood as fishermen. There are more than four groups of fishermen in this village, one of which is a fishermen group of Amerta Segara. The education level of their members are from elementary, middle and high school are dominated by primary school education. The number of members amounted to 25 persons. The encountered often problems on the fishermen is the fish handling a problem. When the harvest that the fish marketing become not good, the price is very cheap and fishermen's income decreases or not the maximum. Lack of knowledge about the fish processing cause fishermen's group is overwhelmed and being resigned on the situation. Seeing this condition, with our dedicated of team doing technical guidance on the fish processing technology to fishermen group of Amerta Segara on the Bugbug village, Karangasem District, Bali Province. The method is used the counseling and evaluation before and after counseling. The results obtained, that the community of the fishing groups of Amerta Segara very seriosly to listen the counseling and an increase in knowledge or understanding on the technologies presented.

Abstract

Production process of boiled [of] sea fish still uses the traditional technology ( boiled with the opened vessel).The business of boiled fish in Kusamba increases quite a lot although it is still traditionally applied. It is the consequence required by effort of development of design system of boiled with the pressure vessel system. System of boiled with the pressure vessel to yield the thrift energy of equal to 25 % compared to by application of boiled standard for the capacities of same and poaching temperature increase to 30? C. The application of boiled with pressure vessel compared to the opened vessel was more effective.

Abstract

Comfort and coolness when traveling by vehicle especially car is highly needed. So many attempts have been made byhumans that comfortable traveling by car can be achieved. One of the effective ways in which comfortable traveling by car can beobtained is by installing air conditioning. The performance of air conditioning system is highly influenced by how the compressorworks. In other words, the pressure resulting from the suction highly determines the performance of air conditioning system,which then affects how the compressor works, the compressor power, the refrigeration effect, the efficiency of isentropic andcoefficient of performance (COP) of the car air conditioning sytem especially that of the car air conditioner type ET 450. Fromwhat has been described above, the writer would like to conduct a research entiled “ Analysis of the Performance of the Car AirConditioning system Type ET 450 with Variation of the Compressor Pressure”.The test was conducted on the car air conditioner type ET 450 with variations of suction 2.8 bar, 3 bar, 3.2 bar, 3.4bar, 3.6 bar and 3.8 bar. The data were obtained from the pressure of compressor output (P2), the temperatures in each point areT1, T2, T3, T4, the compressor rotationn is n, the strength of electrical current is I, and the volumetric flow rate. The data werethen processed and analyzed so that so that the performance of each variation of the suction could be actually and theoreticallyobtained.The findings show that the bigger the suction, the bigger the performance of the car air conditioner type ET 450 wouldbe. The theoretical coefficient of performance (COP) produced was bigger than the actual COP. The optimal COP took placewhen the suction was 441.325 kPa, the actual COP was 3.513177 and the theoretical COP was 3.632062

Abstract

Pengeringan dengan tujuan pengawetan pada industri pangan dilakukan dengan cara konvensional seperti menjemur dan sistem oven. Metode pengawetan lainnya dapat dilakukan dengan dehumidifier. Proses dehumidifikasi dapat menggunakan sistem refrigerasi. Pengeringan dengan dehumidifier ini dapat dilakukan dengan pengamatan pada laju pengeringan pada material uji jamur, kemudian hasilnya akan dibandingkan dengan metode konvensional. Dari penelitian ini dapat disimpulkan bahwa sistem pengeringan dengan dehumidifier lebih baik dari pada sistem konvensional dimana didapat kadar air cukup rendah dan kualitas tekstur tetap segar.
