Abstract

Prototype cars are future vehicles with special designs that maximize efficiency. An important part of the vehicle, one of which is the chassis, which functions to support the passengers, engine, body and the weight of the chassis itself, so it is necessary to design a lightweight and strong chassis. The purpose of this research is to determine and study the stress, strain, displacement and safety factors that occur in the prototype type electric car chassis designed. 3-dimensional design modeling and simulations were performed on Autodesk Inventor software. Based on the simulation results of loading 60kg, the optimal material is aluminum 6061 compared to aluminum 6063 with the results obtained for stress, strain, displacement, and safety factor. on aluminum 6061 with successive values of 59.712 MPa, 0.000796, 1.299 mm, 4.605. While the aluminum 6063 with a value of 59.628 MPa, 0.000806, 1.316 mm, 3.585. The greater the load, the greater the stress and strain.Key words: Chassis, Desingn, Prototype, Simulation

Abstract

The purpose of this study was to determine the effect of the ratio of used cooking oil on the combustion characteristics of polypropylene (pp) plastic pyrolysis fuel oil. This study used a mixture of used cooking oil and pyrolysis oil of 75%:25%, 50%:50%, and 25%:75%, respectively. The results of mixing the used cooking oil are burned using a combustion container in an open space with. The maximum temperature obtained from each mixture was 20 minutes for a mixture of 75%: 25% used cooking oil, a 50%:50% mixture, 42 minutes for a mixture of 25%:75%. is 34 minutes.Key Words: Used cooking oil, plastic pyroliysis oil.

Abstract

Hydroponics is water management that is used as a medium for plant growth, deep flow technique hydroponics is a hydroponic system that circulates water continuously in a closed flow circuit using a pump. DFT hydroponics. This research was carried out by paying attention to the piping system and drawing the installation of the piping system using the Inventor software and then testing. Data collection was carried out by analyzing the supply system, calculating the flow rate, determining the type of flow and performing a strength simulation on the DFT hydroponic rack using the Inventor software application. The research shows the flow rate is 1.43 L/minute and the pump flowrate is 10 L/minute so that the water supply efficiency is 0.143 L/minute (14%). The resulting Reynolds value is 1304.61 m2/s, so the flow that works is laminar flow. Based on the simulation results, the maximum stress on the DFT hydroponic rack is 1616 MPa while the load on the DFT hydroponic rack is 37.8426 MPa so it is safe to use.Keywords:Piping system, hydroponic deep flow tehnique

Abstract

In rural areas, water supply is needed for agricultural, livestock, and fishery activities. In this problem a pump with the right technology, efficiency, and economy is needed so that its management does not depend on fuel and electricity. As a solution to this problem is the use of a hydraulic ram pump. Hydram pumps are an alternative in distributing water from low places to high places. This study aims to design a hydraulic ram pump at Cemping Ground. In this study, the main system is a hydraulic ram pump (hdyram pump) which can drain water from a low place to a high place without using electricity. The flow capacity produced by this pump at a height of 5 meters is 0,000057 (m3/s) or 0,057 (liter/s), the flow rate produced by this tool is 0,00072 (m/s), the efficiency of the hydraulic ram pump produced is 75,83 %, it takes 58,26 minutes per day to meet the 200 L water requirement, for the stress that occurs in the pipe is 0,0554 N/mm2 and for the strain that occurs in the pipe is 0,0000185.Keywords: Alternative, Tool, Design, Pump, Hydraulic
