Abstract

ABC operates within the engineering and construction sector, specializing in the service and provision of advanced heavy equipment, including the DV17 type Dump Truck. This Dump Truck model features a loading and unloading body capable of supporting loads of up to several tons. However, there are noted deficiencies in the effectiveness and efficiency of the Sidewall stiffener section, which utilizes 6 supports. A modification was carried out by creating 3 variants or forms of stiffeners. The design method used is the Pahl & Beitz concept design method, with testing performed through static and dynamic simulations using Finite Element Analysis (FEA). Simulation results show that Variant 2 performed the best in both static and dynamic tests, with static simulation values showing stress at 88 MPa, strain at 0.1, displacement at 0.8 mm, a safety factor of 2.9, and a weight of 818.16 kg. The dynamic simulation for Variant 2 recorded stress at 187 MPa, strain at 0.1, displacement at 1.7 mm, and a safety factor of 1.3. When compared to the existing design by PT. ABC, Variant 2 demonstrates superior performance. The current PT. ABC design presents static simulation values of 301 MPa for stress, strain of 0.1, displacement of 4.7 mm, and a safety factor of 0.8. Dynamic simulations reveal a stress value of 411 MPa, strain of 0.1, displacement of 5.1 mm, a safety factor of 0.6, and a weight of 802.63 kg. This indicates that Variant 2 provides optimal performance and a balanced trade-off between safety and stability.

Abstract

Transportasi merupakan hal yang sangat penting bagi kehidupan masyarakat. Hal ini di karenakan dengan transportasi manusia dan barang dapat berpindah dari tempat satu ke tempat yang lain dengan jumlah yang banyak. Moda transportasi kereta api dikelola oleh PT Kereta Api Indonesia (PT. KAI). Kereta api untuk beroperasi memerlukan bahan bakar B30 sebagai sumber tenaga. Penelitian ini akan membuat perancangan konsep alat filtrasi BBM B30. Dimana alat filtrasi BBM B30 ini akan digunakan untuk menjaga kualitas BBM B30 yang disalurkan dari tangki timbun ke lokomotif. Bahan bakar minyak B30 adalah jenis minyak solar dengan campuran biodiesel 30% (B30) yang ditetapkan dalam SK Dirjen Migas No.146.K/10/DJM/2020. Bahan bakar B30 mengandung banyaknya Fatty Acid Menthyl Ester (FAME) yang menyebabkan banyaknya penggantian elemen filter ROT. Metode yang digunakan dalam perancangan alat filtrasi BBM B30 adalah metode Palhl and Beitz dan melakukan analisis kekuatan kerangka mengunakan Computer Aided Engineering (CAE) dengan tujuan menvalidasi struktur kerangka untuk menerima beban dari seluruh komponen alat filtrasi BBM B30 sebesar 100 kg. Metode eksperimen perencanaan perancangan mengunakan ukuran panjang 1500 mm, lebar 800 mm, dan tinggi 750 mm. Dalam perancangan menunjukan bahwa alat filtrasi BBM B30 mampu menfiltrasi tangki timbun berkapasitas 29.000 liter dengan waktu ±9 jam dengan kapasitas pompa 50 liter/menit dan filtrasi (Out - In) untuk pengunaan elemen filter didapatkan nilai efisiensi yang cukup signifikan sebesar 23,8 %. Telah di lakukan Uji Cleanliness hasil filtrasi dari alat filtrasi BBM B30 di laboratorium Badan Layanan Umum Balai Besar Pengujian Minyak dan Gas Bumi (LEMIGAS) sesuai ISO 4406 di dapat hasil code 18/16/13 yang dimana tidak melebihi code dari standart Diesel Engine dapat disimpulkan sesuai dengan kebutuhan yang diharapkan atau sesuai dengan spesifikasi yang ditentukan

Abstract

The process of peeling and splitting soybeans is a process carried out by industry which uses soybeans to clean the skin and at the same time peeling them using a machine that peels the epidermis and also splits the soybeans can speed up the cleaning process. The machine for peeling epidermis and splitting soy beans uses a pulper as the part that peels and splits at the same time in one machine rotation. This model of machine for peeling epidermis and splitting soy beans is intended for home industries with a processing capacity of 10 kg/hour. The performance capacity test was carried out to test the ability to peel and split soybeans using a tube pulper with soybeans that had been soaked in water for 10 hours previously. Based on the tests carried out, it was found that the peeling and splitting capability of the machine for peeling the epidermis and splitting the soybean seeds was produced based on the initial weight before peeling, the soybeans that were completely peeled were 88.2% and the weight of the waste was 11.8%, peeled in imperfect conditions. broken and not peeled based on the influence of the gap in the peeling space of 2mm.
