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.

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

Hydrogen Electrolysis Power Efficiency Experiment Final Report
Abstract
An experimental research into the power efficiency of hydrogen electrolysis is presented in this work. Hydrogen electrolysis is a promising approach for creating hydrogen as an environmentally friendly and sustainable energy carrier. However, several factors like electrode materials, electrolyte composition, and operating circumstances influence the overall efficiency of the process. A systematic examination of power efficiency was performed in this study by altering these parameters in a laboratory-scale electrolysis cell. The findings show that electrode material has a substantial impact on power consumption and hydrogen production rate. The effects of electrolyte content and operation temperature on efficiency were also investigated. The findings shed light on how to improve the power efficiency of hydrogen electrolysis, which is critical for expanding the commercial feasibility of this technology in a sustainable manner.
I. Introduction
As a clean and adaptable energy carrier, hydrogen has emerged as a possible solution to the challenges of achieving a sustainable energy future. Its prospective uses in sectors including transportation, electricity generation, and industrial processes have sparked considerable interest around the world. Water electrolysis stands out as a major method of hydrogen generation due to its potential to generate hydrogen from renewable energy sources such as solar and wind. The process of splitting water molecules (H2O) into their basic elements, hydrogen (H2) and oxygen (O2), is known as electrolysis. This chemical process takes place in an electrolyzer, which is made up of two electrodes immersed in an electrolyte solution. When a direct current is provided, the cathode attracts and reduces positively charged hydrogen ions (H+) to make hydrogen gas (H2), while the anode attracts and oxidizes negatively charged hydroxide ions (OH-) to produce oxygen gas (O2). This paper aims to investigate the power efficiency of hydrogen electrolysis through a comprehensive experimental approach. By systematically varying key parameters such as current density, electrode materials, and electrolyte composition, we seek to understand the factors that influence the efficiency of the electrolysis process. Furthermore, we aim to explore the potential of optimizing these parameters to enhance power efficiency and contribute to the development of more efficient and sustainable hydrogen production systems. The findings from this research have significant implications for the design and optimization of electrolysis systems. By identifying the factors that influence power efficiency, we can provide insights to guide the development of advanced electrolyzer technologies, inform policy decisions regarding hydrogen production, and contribute to the broader goal of achieving a carbon-neutral and sustainable energy ecosystem.
