<![CDATA[Saat ini di indonesia sepeda motor merupakan alat tranportasi yang sudah di produksi massal. penggunaan sparepart sepeda motor antara yang merek satu dengan merek yang lainnya sudah umum dilakukan dikarenakan komponen tersebut terkadang sulit didapatkan di pasaran. Entah karena sparepart sepeda motor tersebut tidak lagi diproduksi oleh pabrikan atau memang ada faktor-faktor lain yang mempengaruhinya. Poros adalah salah satu komponen sepeda motor , dimana poros merupakan salah satu bagian yang terpenting dari setiap mesin. Peranan utama sebuah poros adalah untuk mentransmisikan daya dari satu elemen mesin ke bagian elemen mesin lainnya. Daya tersebut dihasilkan oleh gaya tangensial dan momen torsi yang hasil akhirnya adalah daya tersebut akan ditransmisikan kepada elemen lain yang terhubung dengan poros tersebut. Poros roda merupakan salah satu komponen yang saangat penting dari sebuah sepeda motor karena poros berfungsi untuk menopang body, beban kendaraan itu sendiri maupun beban luar pada kendaraan dalam hal ini manusia atau barang muatan pada sepeda motor. Sehingga di perlukan poros yang baik untuk mencapai fungsi dari poros tersebut. Dipenelitian ini akan membahas tentang Poros dengan beban puntir dan lentur yang bertujuan untuk memberikan pengetahuan tentang poros depan, Lebih menambah wawasan pengetahuan dalam bidang otomotif dan Mampu merencanakan secara sistematis elemen-elemen mesin yang ada pada system kerja poros.

<![CDATA[Almost every year, floods disaster becomes the scourge of many countries in the world, including Indonesia. When the flood comes and submerges the houses, every item and household furniture in it will also be submerged in flood water. Furniture that is heavy and difficult to move, especially electronic equipment such as refrigerators, may be left by the owner when a flood occurs. To prevent the furniture from submerging, a lifting kit is needed. For this reason, the purpose of this work is to design a mechanical tool/kit that can lift or elevate the electronic furniture such as refrigerator to a higher position and avoid the damage caused by flood. The kit is expected to be able to cover a 100 x 80 cm base of the refrigerator with maximum load of 200 kg. The elevation of the lifting kit is set to be higher than 50 cm. Calculation for the stress and fatigue analysis is also performed to determine the strength of the structure. As a result, the obtained safety factors for the critical components under static and fatigue loading conditions show values of more than one, indicating the product is safe for real operation. In addition, the required torque to produce the elevation is also calculated and discussed.]]>

<![CDATA[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.]]>

<![CDATA[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]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[CO2 Dispersion Consequences Study using 3D CFD method in a CCUS facility Abstract Carbon Capture Utilization and Storage (CCUS) is a method and technology for CO2 gas injection that enables the capture and storage of CO2 underground. The aim is the CO2 emission reduction into the atmosphere as well as enhancing oil/gas/heat recovery. Unlike their counterparts in USA and Europe, however, the CCUS technology in China is not yet mature or still at a pilot scale. Given the large quantities and flow rates which will be used for CCUS, consequently, major releases could produce significant hazard ranges at concentration high enough to have toxic effects. This paper focuses on the consequence of CO2 releases to the neighbourhood or environment which varies in elevations to study the effect to the varied ground levels from the release points to the extent of CO2 dispersion. The effect of large equipment to the CO2 concentration extents is also discussed. ]]>
