Abstract

3D scanner that uses image sensors requires the role of a computer that includes a data generator, data acquisition, and visual display. In a simply system, it can be designed the sensory system uses non-imagery sensor so the role of the data generator can be handled by the microcontroller. This research aims to make a simple 3D scanner using inexpensive non-imagery Time of Flight VL53L0X sensor and data processing can be processed directly by the microcontroller. The results of sensor distance measurements are processed on the microcontroller and desktop application. The distance and angle values are converted into Cartesian coordinate using cylindrical coordinate system. The scan results of the cubes, prisms and cylinder are similar with the reference object, but the results of the pyramid test at the top cannot be scanned properly due to the narrow surface. The laser beam from the emitter cannot bounce back to the collector properly makes distance reading is inaccurate and causes error in the point cloud conversion. The comparison error between the side of the scan results and the reference object is between 2.54-39.8%. The surface of objects with bright color has a smaller error than those with dark color. The comparison error of the height of the scan results with the reference object is between 5-32%. The angle of the emitter exclusion cone and the collector exclusion cone sensor affects the error at the side and height of the scan results.

Abstract

The die design process for casting requires repeated testing in order to get a good die and produce a product that is as planned, which takes a long time and costs a lot for die making in this trial. The purpose of this study is to determine a more efficient process in die design by conducting a casting analysis using a MagmaSoft simulation. The sample part used in this study is a motorcycle brake master cylinder which will be made by the Gravity Casting process with aluminum material. The basic method used is die design using CAD by calculating Shrinkage allowance, and casting simulation using MagmaSoft software to find out various possible defects during the casting process, such as filling, air trap, solidification, hot spots, and shrinkage porosity. The simulation results show that in the filling process there is no indication of cold shot and no air trap problem, solidification and hot spots are good and occur in the part area, and there is little porosity. In general, the simulation results show that the die design has met the requirements, although there is porosity, this porosity occurs in the area that will be lost after the machining process

Abstract

Sampah perkotaan ini merupakan suatu bahan yang terbuang atau dibuang sebagai hasil aktivitas manusia maupun proses alam yang belum memiliki nilai ekonomis. Pengelolaan sampah yang diselenggarakan oleh dinas terkait saat ini hanya fokus pada pengumpulan dan pengangkutan ke Tempat Pembuangan Akhir (TPA) tanpa melalui pengolahan tertentu. Akibatnya sampah hanya menumpuk di sudut-sudut kota sampah yang menumpuk saja dapat membawa dampak yang buruk pada kondisi kesehatan manusia dan lingkungan. Bila sampah dibuang secara sembarangan atau ditumpuk tanpa ada pengelolaan yang baik, akan menimbulkan berbagai dampak yang lebih serius. Terjadinya bencana (ledakan gas metan, tanah longsor, pencemaran udara akibat pembakaran terbuka dan lain-lain) merupakan akibat dari pengelolaan sampah yang belum dilaksanakan dengan baik. Oleh karena itu perlu adanya sistem penangkapan metana dan pengubahan biogas menjadi energi menawarkan salah satu alternatif bagi pengelolaan sampah terpadu untuk mengurangi dampak lingkungan sekaligus menghasilkan energi terbarukan. Studi ini diperlukan untuk dapat mengimplementasikan potensi yang ada tersebut sehingga akan berdampak positif bagi perekonomian dan lingkungan di wilayah yang distudi. Dalam hal ini penelitian dilakukan untuk TPA Burangkeng, Kabupaten Bekasi. Jawa Barat.

Abstract

An analysis of the relationship between locomotive speed and wind direction was carried out on the amount of drag force faced by the CC203 locomotive, one of the fastest locomotives used in Indonesia today. Based on the results of the analysis, an alternative geometry option was made for the CC203 locomotive’s nose. In the geometry option, changes are made to the front structure of the locomotive in order to reduce the amount of air drag that occurs. Based on the results of the analysis that has been carried out, the greater the speed of the locomotive, the value of the drag coefficient will tends to be constant, but the overall value of the drag force will increase. In addition, changes in wind direction facing the locomotive will also significantly increase the coefficient and air drag force. In changing the locomotive geometry, the results of geometric options are obtained that can significantly reduce the coefficient and total air resistance force. Locomotive velocity was assumed as resultant of wind velocity.

Abstract

This study aims to determine the effect of variations in quenching media with NaCl on the value of hardness, energy value of the impact and the microstructure phase formed from the carburizing pack. The results showed that the highest hardness value was obtained by quenching 25% NaCl with a value of 136.76 N/mm2 and the lowest value was obtained in specimens without raw material treatment with a value of 119.63 N/mm2, it can be concluded that the higher the concentration of salt, the higher the hardness value. The results of the impack test showed the highest value in the Raw Material specimen with a value of 14,234 Joules and the lowest value on the specimen with 25% NaCl quenching with a value of 5,694 Joules, it can be concluded that the untreated specimen has a good ductility value, while for the specimens undergoing the quenching process, experience agitation. Metallographic test results show the phase of martensive formation in the quenching process and ferlite in Raw Material
