Abstract

Overhaul is a method of engine maintenance where the engine is dismantled and all components are checked and replaced if there is damage. In carrying out overhaul activities, engine trainer  tools are needed, therefore the operator can reach the components in the pinch point. Engine trainers on the market are usually only specific to one engine. However, in this study, a universal engine trainer was designed with various adapter arms that can rotate on one axis. This engine trainer is equipped with a buffer that is useful for reducing vibration when the engine is started. The design of the engine trainer frame was tested for strength using a static load simulation with an engine load of 400 N. The simulation showed that the frame deflection due to the load was 0.7781 mm. This value can be said to be safe from a static load test.

Abstract

Kebocoran ban merupakan salah satu kendala saat mengendarai sepeda motor, terutama jika mengalami kebocoran pada bagian sisi valve, karena alat tambal ban biasa tidak dapat menambal pada bagian sisi valve. Alat tambal ban yang diciptakan pada kali ini adalah agar dapat meminimalisir biaya pada saat terjadi kendala saat berkendara sepeda motor yaitu pada saat ban bocor. Konsep penambahan fungsional alat tambal ban ini adalah yaitu pada alat penekan ban dalam diberi lubang yang seukuran dengan valve ban, sehingga valve ban tersebut dapat masuk ke lubang tersebut. Dengan alat tambal ban ini bagian yang bocor di bagian sisi valve ban dalam dapat ditambal. Proses penambalan pada alat ini seperti alat tambal ban pada umumnya, yaitu menggunakan proses pembakaran/pemanasan menggunakan kompor gas kecil. Keunggulan dari alat ini adalah alat tambal ban ini dapat menambal ban yang bocor pada bagian sisi valve ban dalam tanpa harus mengganti ban dalam.

Abstract

This research investigates the measurement error on Wire EDM cutting products to find the pulse current's problem-solving. One of the machining parameters that affect the precision of Wire EDM is the magnitude of the current. The experimental study carried out by using the pulse current started from 4-Ampere up to 8-Ampere as the research parameters. A chamfer dimension on 6061 Aluminum alloy was investigated with the gd&t method with ISO 5459 and ISO 1101 standard. Statistic method applied and processed on Minitab with Shapiro-Wilk parameter for normal distribution. These experimental studies have a normal distribution that finds the phenomena of 8-Ampere of pulse current generate a large measurement error. Furthermore, in these experimental studies, the usage of a Profile Projector generates a massive measurement error, up to 64.5% compared with CMM. A strong commitment to calibrate the Profile Projector up to date to maintain the machining quality.

Abstract

This research complements the shortcomings of PLTB, namely by adding a Monitoring System to the Wind Power Plant at Batam State Polytechnic. By addition of sensors, installations, and a control panel containing instruments for monitoring wind conditions, Savonius turbine rpm, and pico-generator output electrical characteristics. The method used is conventional, starting from mechanical design, program development, and installation to testing. This study's preliminary results indicate that wind at the PLTB Polibatam location is not continuous. It does not occur, even though the maximum wind speed can reach 8.9 m / s. The implementation of the savonius-type wind turbine in this study can generate electricity around 87.83 kW / week or about 0.61 kW / hour.

Abstract

The research aims to analyze the effect of metering stroke on product quality. Metering strokes relate to product weight and mold capacity. The material used is Polyamide (Nylon) 66, using an ENGEL 50ton capacity Injection Molding machine.  The research method used is an experimental method before mass pre-production with stroke metering variation as a production parameter. A normality test was used to investigate the experimental data. Shapiro-Wilk's formula on Minitab® software was used to process the data. Product defects caused by an improper metering stroke often in the injection process are short mold and flashing prints. The results show that short mold production defects occur when the metering stroke is 60 mm due to the material does not fill the full cavity. Furthermore, flashing occurs when the metering stroke is 70 mm due to out of cavity capacity. Therefore, the appropriate parameter is a 65 mm metering stroke with good quality part results.

Abstract

Pemindahan area pelayaran dilakukan guna memeperluas area pelayanan Batam Marine Ambulance (BMA). Kapal BMA merupakan kapal yang dibuat dengan kerjasama 3 instansi antara lain: Lembaga Amil Zakat (LAZ) Batam, Rumah Sakit Awal Bros Batam dan Politeknik Negeri Batam. Pemindahan area memerlukan kajian secara teknis baik terkait dengan kapal maupun tingkat kebutuhan transportasi yang digunakan. Lokasi pemindahan yang direncanakan adalah dari pelabuhan Tanjung Punggur menuju ke Pelabuhan Belakang Padang (Sekupang). Pemindahan ini diharapkan dapat meningkatkan taraf kesehatan masyarakat dan kemanfaatan dari BMA. Dari hasil kajian awal dan literatur didatapkan data bahwa, banyak masyarakat yang masih membutuhkan adanya sarana taransportasi yang tidak berbayar untuk melayani kesehatan. Hal ini terlihat dari banyaknya warga yang enggan untuk memeriksakan kesehatan karena kendala pada pembiayaan transportasi. Dari segi teknis terkait dengan kondisi perairan, area pelayaran lama dan area pelayaran yang direncanakan tidak memiliki perbedaan yang signifikan, sehingga untuk dampak lingkungan terhadap gerakan kapal dirasa tidak akan begitu jauh dan masih memiliki performa yang sama.

Abstract

This study aims to test the performance of the Batam Marine Ambulance model as a medical and logistics support fleet using the comparison ship method. A series of stability and motion analysis processes were carried out, then the results were assessed to determine the best design among the proposed design options. Performance tests used three ship models (Model I, Model II, and Model III). It is known that in the stability test, the tilt angle of model III is 33.63° and the maximum GZ value is 4.673 cm. Then, in the resistance test, Model I has a lower resistance of 87.29 N and the required power is 1496.93 W compared to the other proposed models. In the seakeeping test, Model III was found to be more stable or less affected on all surface conditions because the RAO value was relatively lower, namely 90o in terms of heaving, rolling, and pitching at 135o and 180o then had lower additional resistance. The Model III design has good ship stability, drag, and seakeeping characteristics.

Abstract

The development of manufacture Industries in the world rapidly increases especially in Indonesia. One of the manufacture industries is pipe fitting. PT Flo Bend Indonesia is the only manufacturer of pipe fitting steel and iron in Indonesia. The production process of pipe fitting is carried by the machining process. Quality of product produced by PT Flo Bend is depended on jig and fixture. Some of the problems that often appear are the variation of the material dimension that can disturb the beveling process. The time is needed to be longer to change the jig and fixture that suitable with material that needs to be cut. Therefore, this study was conducted to solve the problems by designing the jig and fixture that are more flexible and can adjust to the varying material dimension. The design focuses on the varying of concentric reducer size. Fishbone diagram was used to analyze the problems so that the approximate design concept can be determined. The result of FEM simulation shows 27,3 Mpa for the stress maximum and 8,1 for Factor of safety. Based on FMEA simulation, the design can reduce the time almost 600 minutes. In addition, the design can reduce the cost of the process. Therefore, it can be concluded that the design concept is safe to use.
