  • Investigasi sifat mekanis sambungan Dissimilar Friction Stir welding
           (DFSW) Aluminium Alloys (AA5052 to AA6061)

    • Authors: Muhammad Arsyad Suyuti, Apollo ., Muhammad Iswar, Rusdi Nur
      Pages: 49 - 53
      Abstract: The joint for two different materials (AA5052 and AA6061) can be done by the Dissimilar Friction Stir Welding (DFSW) process. Therefore, this study was conducted to analyze the mechanical properties of dissimilar welding joints. In this study the DFSW process uses a tool with a shoulder Ø 17.8 mm and a cylindrical pin Ø 5 mm. FSW blocking is done on conventional milling machines with 1300 rpm, 1950 rpm and 2850 rpm tool rotation variations, while the welding speed variations are 43 mm / min, 130 mm / min and 240 mm / min. The results of mechanical properties testing showed the highest hardness value obtained was 55.3 HBN at 1300 rpm with 240 mm / min feeding, the highest tensile strength occurred for 1300 rpm and 240 mm / min feeding at 123.51 MPa. The fracture of the tensile test results generally occurs in the HAZ area and the AA5052 base metal Nugget. Investigation results show that the DFSW connection of aluminum alloy material AA 6061 and AA 5052 adapt is well connected, but in terms of general strength the tensile strength of the joint (HAZ and Nugget) is smaller than the tensile strength of the base metal. This DFSW connection adaptation is applied to connections that do not accept load or tensile strength due to the load received by the connection not to exceed the maximum tensile strength of base metal AA 5052

  • Simulasi CFD Pengaruh Konsentrasi Nanofluida Al2O3/Air Terhadap Performa
           Perpindahan Panas Pipa Radiator

    • Authors: Yoga Arob Wicaksono, Sudarno ., Nanang Suffiadi Akhmad
      Pages: 54 - 58
      Abstract: The performance of heat transfer on a car radiator can be improved by using nanofluids as working fluids. In this study analyzes the of heat transfer performance of Al2O3/water nanofluids that pass through cylindrical pipes in 3D using the CFD simulation method for single phase approach. This research studied the effect of nanofluid concentration  0.1, 0.5, 1 and 1.5% on the heat transfer coefficient. The Reynolds number is varied between 9000 to 23000 and the ambient temperature is constant. The results showed that 1.5% Al2O3/water nanofluid increasing heat transfer coefficient up to 5.7% compared to base fluid.

  • Water-Cooled Chiller Terintegrasi Heat Recovery System pada Industri
           Perhotelan di Bali

    • Authors: Made Sucipta, Ida Bagus Oka Jeve, Ketut Astawa
      Pages: 59 - 62
      Abstract: Performance testing of water-cooled chiller integrated with a heat recovery system has been carried out at a hotel in Bali. After commissioning, testing is carried out for 2 days to determine the readiness of the components in operation. The coefficient of performance which is the reference in this study is used to determine the performance of the system with a capacity of 275 tons of refrigeration which is divided into the coefficient of performance of the refrigeration system and the coefficient of performance of the total integrated system. Data was collected with 8 hour intervals starting at 06.00, 14.00, and 22.00 Wita every day. This condition is based on the prediction of the cycle of changes in energy use in the hotel, which includes breakfast, hotel check-in and bedtime. From the research results, it was found that with the condition and situation of the hotel were not measured properly and the occupancy rate of the hotel which was not yet maximal resulted in a greater refrigeration capacity on the second day, but this was also followed by a large demand for compressor power. Although in the end the coefficient of performance was slightly larger than day 1. It was also found that the greatest need for heat transfer rate is required at 22.00 Wita during the 2-day test. This is possibly due to the need for hot water for hotel guests to shower at night. In general, an increase in the coefficient of performance is still possible if there is an increase in hotel occupancy rates.

  • Rancang Bangun Prototipe PLTPh Sebagai Listrik Penerangan Kapasitas 9 Watt

    • Authors: Muhammad Ibrahim, Iman Dirja, Viktor Naubnome
      Pages: 63 - 69
      Abstract: This study aims to realize the manufacturing of a prototype design of a pico-hydro power plant, which is expected to be a science of study and a reference for students at the University of Singaperbangsa Karawang in particular and Indonesian students in general, as well as monitoring the performance test of the prototype of pico-hydro power plant that is used as an electricity needs for lighting. The design and manufacture of this prototype require several supporting components: a). Pressure gauge; b). Pelton type turbines; c). Tacho Meter; d). Single-phase Ac generator; e). Avometer; f). Energy saving LED lamp. Pico-hydro power plant prototype testing is carried out by measuring the voltage generated by the generator, tested at no load and given a load using variations of 55%, 70%, 85%, 100% valve openings. Based on the results of the performance test, the pico-hydro power plant can work well. That matter can be seen from the largest flow valve opening which results in a high water flow rate, so that it can rotate the turbine quickly. The flow rate greatly affects the generator rotation. No-load test results, the largest voltage of 90 volts is obtained when using 100% valve opening, with the output producing an air flow of 0.0017 m3 / s, rotation (N1) 136 rpm, rotation (N2) 979 rpm. The results with the load, the largest voltage of 60 volts is obtained when using 100% valve openings, with the output producing rotation (N1) 133 rpm, rotation (N2) 957 rpm, and current 0.13 A when supplying the 4 LED lamps type of 3 watts with litting up brightly.

  • Pendekatan Malcolm Baldrige Criteria For Performance Excellent (Education
           Criteria) dalam Perancangan Sistem Pengukuran Kinerja Fakultas Teknik
           Univeritas Udayana menuju Sertifikasi AUN-QA

    • Authors: I Made Dwi Budiana Penindra, I Made Gatot Karohika
      Pages: 77 - 81
      Abstract: The Faculty of Engineering, Udayana University is one of the faculties in Udayana University. The Faculty of Engineering has 5 departments that have a lot of interest. Currently, the Faculty of Engineering is preparing to support Udayana University in obtaining the Asean University Network - Quality Assurance (AUN-QA) certification which is targeted for a visitation in 2021. One of the supporters in obtaining this certification is that the Faculty of Engineering must have a performance measurement system. In this research using an integrated performance measurement system that designed through the Malcolm Baldrige Criteria For Performance Excellent (Education Criteria) approach which is integrated with several methods, namely IPMS in determining the Key Performance Indicator (KPI) which becomes a determining indicator of later performance. assisted by using the Analytical Hierarchy Process (AHP) method in giving the weight of each KPI. After the KPI has a weight, then a comprehensive scoring is carried out using the Objectives Matrix (OMAX) method so that an index number per period is generated which is the reference for the level of performance of the department, as well as a Traffic Light System (TLS) to find out which KPIs require improvement based on color. With the creation of an integrated performance measurement system, it is hoped that the Faculty of Engineering can make continuous improvements. The results showed that the Performance Indicator from the Faculty of Engineering in this period was 427.19 with 24 KPIs being measured. The Performance Indicator shows that the overall performance of the Faculty of Engineering is above average (300). Only 2 categories are in the red zone of 21%, namely Student Criteria (KPI 1 and KPI 4) and Management Criteria (KPI 18, KPI 19, and KPI 20). In the following year, the Faculty of Engineering must focus on the five KPIs so that later they can improve performance.
