Abstract

Rice is a strategic commodity that directly affects the lives of the majority of the Indonesian population, therefore the program to increase rice production gets a top priority from the government to achieve food security and farmers' welfare. The work of farmers in order to increase domestic rice production, for example is the Rice Milling Unit (RMU). The technology that is usually used in producing grain into rice, one of which is a husker (husker) machine. grains of rice, in the rice mill there is a husker machine weighing 115 kg which is only based on the floor so the machine requires a support or foundation so as not to cause vibrations that can damage the structure of the building around it, therefore it is necessary to make a design the support frame is sturdy and also flexible. To determine the strength of the frame, it is necessary to analyze the calculation of the frame simulation which includes the simulation of Von misses, Displacement and Safety factor, the simulation is carried out at a load of 1127 N which produces a Von misses max value of 102,486 MPa, with the highest displacement value of 0.274 mm and the lowest value of 0. mm, and produces a safety factor value of 2,439. with the value of the safety factor, it can be said that the frame construction is safe.

Abstract

Pada era modern ini di negara berkembang dengan tingkat populasi yang tinggi, sarana transportasi yang paling umum digunakan adalah kendaraan roda empat (kendaraan keluarga). Berbagai parameter yang mempengaruhi tahanan aerodinamik pada kendaraan mobil dapat diklasifikasikan dalam tiga kelompok: (1) parameter posisi, yang menyatakan kedudukan kendaraan terhadap bidang permukaan jalan, (2) parameter fungsional, yang menyatakan kondisi bagian kendaraan yang mempunyai tugas tertentu seperti kaca jendela terbuka atau tertutup, (3) parameter bentuk, yang menyatakan bentuk badan kendaraan yang dapat dikuantifikasikan, seperti kemiringan permukaan atas. Bentuk bodi direkayasa sedemikian rupa untuk menghasilkan karakteristik aerodinamika yang optimal. Pada penelitian kali ini penulis ingin menganalisa aerodinamika pada ahmed body car dengan modifikasi desain pada bagian belakang model degan sudut kemiringan 0º menggunakan teknik CFD (Computational Fluid Dynamic) pada software Ansys Workbench 18 di varian kecepatan 80 km/jam, 100 km/jam, dan 120 km/jam. Hasil penilitian menunjukan bahwa coefisien drag terkecil adalah 0.54016 yang terjadi pada varian keceptan 80 km/jam dan yang tertinggi 0.59575 yang terjadi pada varian kecepatan 120 km/jam. Sedangkan untuk distribusi tekanan maksimum tertinggi sebesar 9.209x103 Pa terjadi pada varian kecepatan 120 km/jam. Begitu pulak yang terjadi dengan distribusi kecepatan maksimum tertinggi terjadi pada varian kecepatan 120 km/jam sebesar 220.6 m/s. Untuk nilai distribusi tekanan maksimum dan distribusi kecepatan maksimum terkecil yaitu 4.087x103 Pa dan 148.5 m/s berturut-turt yang terjadi pada varian kecepatan 80 km/jam.

Abstract

Kompresor adalah salah satu alat bantu yang dapat menggerakan mesin-mesin industri dengan sistem pneumatic dimana kompresor konsep kerja nya merubah energi listrik menjadi energi gerak. Tujuan penulisan adalah memahami mekanisme dari Compressed Air System, memahami mulai dari mekanisme, spesifikasi pada sistem kompresor mulai dari kompresor, particular filter, air receiver, air dryer dan fine filter. Menganalisa perhitungan volume yang dibutuhkan pada industri. Selanjut nya mencari data tentang sistem kompresor di PT. Agya makmur mengenai materi sistem kompresor beserta alat-alat lain nya pada sistem kompresor tersebut, yaitu kompresor, air receiver tank, particular filter, air dryer, dan fine filter. Selanjutnya menjelaskan sistem kompresor, seperti kompresor tipe screw memiliki beberapa komponen seperti air intake, intake valve, air and screw, oil sparator, air and oil cooler, dan oil filter komponen tersebut memiliki spesifikasi masing-masing dan mempunyai kegunaan nya masing-masing. Lalu melakukan penelitian mengenai menganalisa perhitungan volume yang dibutuhkan yang sesuai kebutuhan dan paling efisien digunakan dengan menggunakan rumus FAD. Dimana hasil yang di dapat pada perhitungan FAD untuk menentukan kompresor yang efisien.

Abstract

Distillation or simple distillation uses the principle of separating two or more liquids based on differences in the boiling points of each component. The distillation process itself has two main stages, namely the evaporation stage and the condensation or condensation stage. Therefore, distillation equipment uses a heating device in the form of a boiler and a cooler in the form of a heat exchanger. In the refining process, the heart of the distillation system lies in the boiler as a steam producing component. Therefore, the effectiveness of the boiler to produce saturated steam greatly determines the results of the refining process. To determine the power of the boiler, it is necessary to analyze the Boiler simulation calculations which include Von misses, displacement and safety factor simulations. The simulation is carried out at a pressure of 4.5 Bar which produces a Von misses max value. of 3.444 MPa, with the highest displacement value of 0.002 mm and the smallest value of 0 mm, and produces a safety factor value of 75. With this safety factor value, it can be said that the frame construction is safe.

Abstract

The following paper was made to understand the process, and defects from metal casting of Low Carbon Steel GS-25 CrMo 4 Bucket Teeth Adaptor for Excavator with furan molding method and how the results of the Chill Test on the product. Metal casting process of making objects by melting metal and pouring it into a mold cavity. Metal casting has been discovered and continues to be developed, one of which is Sand Casting, where there are various types of methods in making molds including the Furan, Disamatic, and Jolt Squeeze methods. The method used in this research is the Furan method which can be used to make objects with complex shapes such as the Adaptor component used in the Bucket Teeth for Excavators. The casting material used in this casting is GS-25 CrMo 4 steel which has strong and tough properties. All manufacturing processes are carried out through several stages, namely; design, model and core making, mold making, smelting, pouring, fettling and finishing, and quality control. From the results of the research that has been carried out, it can be seen that several rejections from these products include: cold shut, missrun, inoculant inclusion, slag inclusion, and sand inclusion.
