Introduction

Hello everyone, my name is Muhammad Dhia Andriyanto - 2006517796 currently this is my 6th semester in Mechanical Engineering at Universitas Indonesia. This page is my summary about Energy Conversion System 2.

Chat With ChatGPT

on 21 February 2023, my friends and I chat with ChatGPT regarding the correlation between sugar cane factory, automotive factory, and oil & gas factory. When I asked ChatGPT about this topic, ChatGPT said that the correlation is the use of ethanol and its production process.

One potential link between these factories is that they are all part of the same supply chain. The sugar cane factory, for example, may supply sugar to the automotive factory, which uses it to make ethanol for fuel. The oil and gas factory may also supply fuel to the automotive factory, and some of the ethanol may be used as a blend component for gasoline. Furthermore, the oil and gas plant may provide diesel or other fuels to power the sugar cane factory's machinery. The energy is required by the sugar cane factory to power its machinery and process the sugar cane into sugar or ethanol. Fuel is required by the automotive factory to power its assembly lines and other operations. Energy is required by the oil and gas industry to extract, refine, and transport oil and gas. These factories may also be connected in terms of electricity or heat supply, depending on their location and available energy sources.

All of these factories have the potential to have serious environmental consequences. If the sugar cane factory relies on clearing land for new plantations, it may generate waste that must be disposed of or contribute to deforestation. The automotive factory's manufacturing processes may pollute the air or water, or it may contribute to greenhouse gas emissions through the use of fossil fuels. Of course, the oil and gas factory is directly involved in the extraction and processing of fossil fuels, which have numerous environmental consequences.

Apology

On Friday, 24 February 2023...I went to class 15 minutes late and Mr. DAI, Bang Tanwir, and my friends are already in class. I feel terrible and regret for what I did. Hope for the best for the future. Thank you Mr. DAI, Bang Tanwir, and friends

Class Summary

24/02/2023

On this date, my friends and I were given a tutorial by Bang Tanwir regarding how to burns fuel and air to produce power and fuel gases on Internal Combustion Engine using OpenModelica. by using OpenModelica there were ThermosysPro library inside the application and used the ICE (alternating Engine), Fuel Source, Air source, Sink, Water, and singularPressureLoss.

Desalination is the process of removing excess salt content from water in order to create water that can be consumed by humans, animals, or plants. Solution to the Clean Water Crisis. Desalination, which converts seawater with a high salt content that is unfit for consumption into drinkable fresh water, is one solution to the clean water availability crisis that frequently occurs in Indonesia.

By utilizing seawater and processing it as drinking water, we are also reducing the use of underground water, which is thought to be the primary cause of land subsidence in various locations, particularly in Jakarta. Unfortunately, it is difficult to find investors due to the expensive equipment for desalination.

The future for water purification/filtration is using Graphene. In the laboratory, graphene oxide membranes have been shown to be extremely effective at removing contaminants from water. Today's graphene membrane research is bringing the possibility of providing clean, safe drinking water to human being.

Calculating & Modelling The Efficiency Combination Between Air and Fuel on Gokart 2-Stroke Engine For Race Purpose

I. Abstract

II. Introduction

A go-kart is a four-wheeled vehicle that lacks suspension and a differential. It is a lightweight racing vehicle that is used for racing. In comparison to other vehicles, the go-kart has a low ground clearance. Engine, wheels, steering, axle, and chassis are the components of a go-kart. The go-kart uses a 150cc engine. In this case, I used Ninja 150 Super Kips 2-Stroke Engine.

III. Preliminary Question

1. Does setting a carburetor affect engine performance?

2. What is the best setting of engine for race purpose?

3. Does External factor affect engine performance?

IV. Literature Study

A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston up and down during one power cycle, with this power cycle being completed in one crankshaft revolution. A four-stroke engine needs four piston strokes to complete a power cycle in two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the start of the compression stroke occur simultaneously, as do the intake and exhaust (or scavenging) functions.

Two-stroke engines frequently have a high power-to-weight ratio, with power available in a limited range of rotational speeds known as the power band. There are fewer moving parts in two-stroke engines than in four-stroke engines.

Electrolysis Project Report

I. Introduction

Michael Faraday popularized the term "electrolysis" in the nineteenth century. It was a method for studying chemical reactions and obtaining pure elements. Electrolysis is now commercially important because it is widely used to separate or obtain pure elements from naturally occurring sources such as ores.

II. Literature Study

Electrolysis is a promising method for producing carbon-free hydrogen from renewable and nuclear resources. The process of splitting water into hydrogen and oxygen using electricity is known as electrolysis. This reaction takes place in a device known as an electrolyzer. Electrolyzers can range in size from small, appliance-sized equipment suitable for small-scale distributed hydrogen production to large-scale, central production facilities that could be directly linked to renewable or other non-greenhouse-gas-emitting forms of electricity generation.

Electrolysis involves the exchange of ions and atoms caused by the addition or removal of electrons from the external circuit. In general, when current flows, cations move to the cathode, take electrons from the cathode (provided by the supply source-battery), and discharge into the neutral atom. If the neutral atom is solid, it is deposited on the cathode; if it is gas, it moves upwards. The cation is reduced at the cathode during this reduction process. At the anode, water reacts to produce oxygen and positively charged hydrogen ions. (protons). Hydrogen ions combine with electrons from the external circuit at the cathode to form hydrogen gas. Reaction at the anode: 2H2O O2 + 4H+ + 4e- & Cathode Reaction 4H+ + 4e- 2H2
