Abstract

Now, many of piston ring parts have been on the market. The products are often encountered are the 5MX-E160-10 series piston ring and the SLW-E1603-20 series piston ring which have different qualities. In this study, the hardness of the two piston ring products was analyzed by heat treatment. The heat holding time was varied 15 minutes, 30 minutes and 45 minutes at 8000C and the quenching media of SAE 40 oil. The results of the hardness of the 5MX-E160-10 series raw material were 105.97 HRB and the highest hardness value after treatment decreased 34.02% were 71.95 HRB. While the hardness value of the SLW-E160-20 series raw material were 90.26 HRB and after the heat treatment has decreased by 19%, were 71.26 HRB. The best microstructure test results were found at the 30 minute holding time series 5MX-E160-10 with a temperature of 8000C and the quenching media of SAE 40 oil. In addition, the results showed that the longer holding time in the SLW-E1603-20 series resulted in decreased hardness values.

Abstract

Tujuan dari penelitian ini adalah untuk merancang fluid fruction aparatus, dengan variasi pipa elbow berdiameter 1¼inc, 1inc, ¾inc, ½inc dengan tinggi 10 cm. Hasil penelitian menunjukkan bahwa penggunaan elbow dengan variasi diameter pipa akan menghasilkan turbulensi yang besar dan mengakibatkan hilangnya aliran pada pelepasan yang dihasilkan, yaitu semakin besar diameter pipa yang digunakan, semakin tinggi turbulensi dan gesekan yang terjadi. Sebaliknya jika diameter pipa yang digunakan semakin kecil, turbulensi dan gesekan yang dihasilkan akan kecil juga. Kata Kunci : debit, diameter pipa, rugi belokan

Abstract

This study of the influence of variations in pulley diameter driven on shallot chopper machines against the chaff yield capacity is motivated by the production and consumption of shallots in Indonesia is quite high, so it takes a red onion chopper machine to facilitate the handling and processing. The purpose of this study was to make a shallot chopper machine, to analyze the effect of variations in pulley diameter on the yield of onion chopping, and to analyze the results of onion chopping. In this study, the analyzed were chopper speed with variations in pulley diameter driven 6 inch, 7 inch, 8 inch and 1½ inch drive pulley diameter. The test method uses 200 grams of shallots per experiment with repetitions three times the experiment with variations of pulley driven 6 inches, 7 inches, and 8 inches. After testing, an analysis of the data obtained in the form of chaff yield capacity is completed. The best test results were obtained using variations in pulley diameter driven by 6 inches with a chopping yield capacity of 3.77 grams / second.

Abstract

The land area of peanut plantations reached 314 Ha, making Tegalrejo District a peanut center in Magelang Regency. As a center for producing peanuts, the demand for peanuts in Tegalrejo District is also high. The high demand makes the need for the application of technology in producing peeling peanuts. Based on the problems faced and the existing literature review, it is necessary to develop a peanut stripper that is good in stripping capacity and the quality of the peel. The purpose of this study was to analyze the effect of the distance between peanut peeling machine on the quality of the peel. The study was conducted with 3 repetitions with 1 kg of peanuts per data collection. The results obtained from the study are variations in the distance of 15 mm of test yielding the highest percentage of peanut peanut value of 80.96%. Whereas the highest capacity is obtained by varying the 20 mm peanut peeling distance, which is 28.48 kg/hour.

Abstract

Indonesia has the potential of water that can become electricity with a hydroelectric power plant. In addition, the distribution of the PLN network has not reached all regions of Indonesia. From these problems the author made a hydropower generator by comparing the number of blades used with a number of 8, 10, and 12 pieces. This study aims to determine the power that will be generated from the number of blades. Data retrieval is done by calculating the power produced by the turbine with a variation of the test time of 20 minutes by 5x. The working principle of this tool is that the water will rotate the wheel connected to the generator with the help of shafts, bearings, pulleys, and V-belts that produce electrical power in the battery so that the electricity can be directly used. The results obtained that the output power is the largest in the use of a number of 12 pieces of blades namely 0.0687 HP, while the number of blades 8 and 10 pieces produces the amount of output power of 0.0627 HP and 0.0652 HP.

Abstract

Entrepreneurial education (EE) is a process facilitating individuals to recognize, to assess, and to execute business opportunity. Besides, it is also developed as a process to enhance awareness on opportunity recognition, knowledge, self-esteem, and capability to act in various contexts (Morris, Webb, Fu & Singhal, 2013, Jones dan Engish (2004). Entrepreneurial Education has become something beyond business, but also as means or methods to build entreprenurial competences which are also impactful towards the betterment of adaptibility and competitiveness (Allan Gibb, 2002; Mwasalwiba, 2010).

Abstract

This community service activity has been carried out at the Miftahul Jannah Putri Tahfidzul Qur'an Islamic Boarding School in Pamanjengan, Moncongloe, Maros Regency. This Islamic Boarding School for Qur’an Memorizer fosters 10 children from families with underprivileged economic conditions. The capacity of the pondok buildings can accommodate more number of students, but water supply is a big problem. Therefore, the management of the school has attempted to add groundwater production wells through financing from other parties. Drilling was carried out to a depth of 60 meters. The well pumping test with a discharge of 1,440 liters/hour showed a change in the groundwater level to become static at a decrease of 1.60 meters. Thus, the condition prior to this community service activity was that there were production wells but had not been equipped with submersible pump wells. Information from the pre-test indicated that the students still felt limited clean water. Therefore, through Hasanuddin University's P2C-IKU activities, pump installations are carried out to be able to utilize groundwater from the drilled wells. The results of the post-test at the end of this activity showed that 83.30% of respondents believed that there would be sufficient water supply to meet the needs of the cottage, and 57.14% of respondents understood how to operate and maintain submersible pumps.
