Abstract

Chassis is the main component of the vehicle that functions to support the engine, body, suspension system, electrical system and driver. Chassis is one part of the vehicle that has an important role so careful planning is needed in its manufacture. Chassis must be strong and sturdy to support the load of the driver, electric motor and accessories. In addition, the chassis must also be light so as not to overload the work of the electric motor and be able to go through various road conditions. The vehicle body is its function to shape the vehicle and also protect the people inside. In this design, steel and aluminum materials are used, then simulated using the Autodesk Inventor software. The goal is to determine the Von Mosses stress value on the chassis design. AISI 1018 steel material with a load of 700 kg, 800 kg, and with a load of 900 kg obtained a value of 5.56. The safety factor obtained is still safe because it is above the safety factor for industrial construction design, namely 4. Aluminum 6061 material with a load of 700 kg, 800 kg and with a load of 900 kg obtained a value of 7.46. The safety factor obtained is still safe because it is above the safety factor for industrial construction design, namely 4.

Abstract

Penyediaan pasokan energi pada masa depan merupakan suatu masalah yang selalu menjadi perhatian seluruh masyarakat dunia. Hal ini disebabkan karena sumber penghasil bahan bakar minyak (BBM) yaitu fosil semakin lama semakin berkurang. Salah satu upaya untuk mengurangi konsumsi masyarakat terhadap bahan bakar fosil adalah dengan memanfaatkan energi alternatif terbarukan yaitu bioetanol. Tujuan penelitian ini untuk mengetahui pengaruh dari variasi temperatur fermentasi terhadap kadar dan volume alkohol dari limbah gula (molases) dengan menggunakan mikroaerasi. Metode penelitian yang digunakan yaitu metode experiment. Variasi temperatur fermentasi yang digunakan yaitu 30oC, 32oC, 34oC, 36oC, 38oC. Proses fermentasi dilakukan selama 48 jam terhadap 30 Liter cairan molase. Namun sebelum itu, untuk memproduksi bioetanol dilakukan proses pengembangbiakan mikroorganisme selama 3 jam. Kemudian dilakukan proses destilasi untuk mendapatkan kadar dan volume alcohol dari proses fermentasi molases. Hasil penelitian menunjukkan bahwa faktor variasi tersebut berpengaruh terhadap kadar dan volume alkohol yang dihasilkan. Perlakuan yang paling optimal untuk menghasilkan kadar alkohol paling tinggi adalah temperatur 34oC dengan rata-rata kadar alkohol sebanyak 84% sedangkan perlakuan yang paling optimal untuk menhasilkan volume alkohol paling tinggi adalah temperatur 32oC dengan rata-rata volume alkohol sebanyak 668,7 mL.
