Abstract

The high yield of coconut in Indonesia is positively related to the production of coconut shell waste which is difficult to decompose by microorganisme. Therefore, in recent years a method of utilizing coconut shell waste for charcoal and liquid smoke has been developed. So far, the process of making liquid smoke from coconut fiber (coconut coir liquid smoke) is usually carried out for 3-5 days and the amount of liquid smoke is very small. The use of liquid smoke is also adapted to clarify the qualities of liquid smoke, is used as a wood preservative and thickener, as an antimicrobial agent, and as a natural food preservative. In addition, e-liquid can also be used as a natural preservative for food, meat, and fish, it is also very suitable to be used as a natural substitute for formalin or borax for insect repellent, and a wood preservative which has received wide attention in recent years. Therefore, the purpose of this research is to design a device that produces liquid smoke from burning coconut shells from the distillation process, which can increase the amount of liquid smoke produced.

Abstract

Commercial vehicles are considered to be able to facilitate the logistics process, for example three-wheeled commercial vehicles, but on the other hand the less affordable prices make people spin their brains to modify makeshift vehicles to be used as commercial vehicles by ignoring safety, security, or comfort. Therefore, a minimalist three-wheeled scooter was created to reduce prices but not reduce safety, features, and comfort for the rider or those around him so that they can compete with products in their class. In this final project the author focuses on designing an optimal exhaust system for a minimalist three-wheeled scooter. The exhaust system serves to reduce exhaust noise from the engine and affect the comfort of the rider and those around him. With the Ulrich method, a suitable concept for a three-wheeled scooter will be selected. Based on the results of the calculation and design process on the exhaust system, the dimensions of the exhaust system channel are 433.25 mm x 98.85 mm x 95.13 mm and the muffler is 360 mm x 76.2 mm x 76.2 mm. Fluid flow analysis shows a back pressure of 15.62 Pa in the exhaust system line and 88.17 Pa in the muffler. Noise testing is carried out on the exhaust system and has met the standards of the Ministry of Environment and Forestry of the Republic of Indonesia with the highest test result of 75.2 dB with a standard of 83 dB.
