Abstract

Guna menjaga suhu msein pada rentang 80oC-90oC maka keberadaan sistem pendinginan paksa yang di sebuah mesin otomotif sangatlah mutlak. Komponen komponen yang ada pada sistem pendinginan adalah thermostat, radiator, kipas, sensor dan pumpa air centrifugal. Baik buruknya pendinginan dipengaruhi oleh kipas dan kondisi radiator. Permasalahan utama muncul manakala kondisi radiator kator. Bebarapa solusi yang bisa ditawarkan adalah pembersihan kerak, pemakaian coolant radiator dan inovasi saluran.  Salah satu usaha untuk meningkatkan kualitas pendinginan atau radiator adalah pemanfaatan saluran bersirip yang diletakkan di saluran pra radiator. Tujuan dari pelaksanaan penelitian ini adalah untuk mengetahui efektifitas perubahan suhu kerja  mesin yang dipasang alat bantu pendingin. Metode yang dipergunakan untuk melakukan penelitian adalah penggunaan alat bantu berbahan logam dan aluminium dengan jumlah sirip yang divariasakan (enam dan sebelas). Bentuk alat bantu tersebut adalah selongsong//pipa dengan sirip siirip yang divariasikan bahan dan jumlahnya. Hasil dari penelitian ini adalah adanya kemanfaatan penggunaan sirip. Berbahan logam jumlah sirip  11 penurunannya sebesar 6.7% sedangkan jumlah sirip 6 penurunannya mencapai 6.3%. Pada penggunaan bahan dari aluminium dengan jumlah sirip 11 menunjukkan penurunan sebesar 12.5% sedangkan jumlah sirip 6 sebesar 6.3%. Sedangkan pengaruhnya terhadap radiator dalam proses pendinginan. Pada  bahan logam sirip 11 penurunannya mencapai 22.2 % pada 1250 rpm, pada sirip yang berjumlah 6 penurunannya mencapai 22.2% pada puran mesin 1250 rpm. Pada pemakaian sirip berbahan non logam (aluminium) jumlah sirip 11 penurunannya mencapai 29.4% pada putaran mesin 2000 rpm sedangkan pada jumlah sirip 6 mencapai 27.4%. pada 1750 rpm.

Abstract

The main function of an oil filter in a car is to filter the oil coming from the charter to be circulated to the engine. The main function of the oil between it is as a lubricant and engine coolant. The engine working temperature is affected by the engine cooling system and the oil function which acts as a cooler. One effort to improve the quality of oil cooling can be done with the addition of cooling aids placed in the oil filter. The purpose of this research is to determine the effectiveness of changes in the working temperature of the engine mounted cooling aids on oil filters. The method used to conduct research is the use of metal and aluminum based tools with the number of fins that are varied. The shape of the tool is a metal sleeve with fin fins that vary in number. The results of the temperature scale under the influence of engine speed in this study is the greatest level of decline with variations in the number of fins of 10oC. Whereas with the use of different materials, a 5oC reduction was obtained in the use of aluminum compared to stainless steels.

Abstract

One of the commodities of the creative industry in Indonesia, which until now is still superior, is the batik industry, both batik screen printing batik, stamp and printing. The stages of the production process of stamp batik are the process of tasting, coloring, drying and drying / drying. Problems that arise during the production process in batik UKM Pandanwangi is a coloring process that takes longer and is wasteful of the dye. The existence of a dye or dye tool is needed, a tool that is able to provide a solution to this problem is a peder. The purpose of implementing the partnership program for the community (PKM) is to help provide solutions specifically the problem of the production process. The method developed is a survey of UKM, designing tools, carrying out discussions with partners in relation to the results of tool design, tool manufacturing processes, component performance testing, work testing of tools and production processes. The results of the program are a peder with specifications: size of 157 cm x 149 cm x 144 cm, source of 0.5 Hp electric motor power, transmission (V-belt, pulleys, chains and gears), dye tanks, pressing (2 rollers and fasteners). The speed of the production process for the program results is 15 m per minute. The conclusion of the implementation of the PKM program is that SME partners are able to carry out the coloring / dyeing production process on average ± 2000 m every day.
