ABSTRACT The development of the chemical industry in Indonesia is growing rapidly. One of the chemical industries established in Indonesia is benzene, toluene and xylene (BTX). Benzene, toluene, and xylene (BTX) can be produced through the catalytic reforming process from naphtha. The chemical process that occurs is described as a dehydrocyclodimerization process and thermodynamically this pro…
ABSTRACT Acrylic acid is an organic compound in the form of a colorless liquid which is commonly used in many industries such as the diaper industry, the water treatment industry or the textile industry. In the global market, the consumption rate of acrylic acid is expected to reach more than 8,000 kilo tons in 2020. The high demand for acrylic acid is possibly due to the use of this product f…
[email protected] ABSTRACT Methanol is the simplest form of alcohol. Methanol is often referred to as methyl alcohol, wood alcohol or spirit which includes chemical compounds with the chemical formula CH3OH. Most of methanol, is produced from fossil fuels and more than 85% of global methanol production is based on natural gas reforming and gasification of coal. Biomass is biolog…
ABSTRACT Along with the times, the need for chemicals in Indonesia is getting bigger. One of the most widely used chemicals is ethylene oxide. This chemical, also known as epoxyethane is widely used in the chemical and pharmaceutical industries. The main raw material for the manufacture of ethylene oxide with the DOW Meteor process uses ethylene and oxygen. Ethylene oxide (oxirane) is the …
ABSTRACT The acetic acid industry in Indonesia is one of the chemical industries that has good prospects. This acetic acid product has a fairly wide market such as the Purified Terephthalic Acid (PTA) industry, the ethyl acetate industry, the textile industry, the rubber yarn industry and is also used as a semi-finished material to make chemicals, such as vinyl acetate, cellulose acetate, acid…
ABSTRACT High density polyethylene or high density polyethylene is one type of high-density polymer that is flexible, impact resistant, low temperature resistant, even freeze water resistant which is potential as a matrix candidate in making bone replacement composites. One process that can be used in synthesizing high density polyethylene is the CX-Mitsui process. CX-Mitsui processes there is…
ABSTRACT Polybutylene Terephthalate (PBT) is a type of synthetic plastic that is nonbidegradable or cannot be degraded by microorganisms. Polybutylene Terephthalate (PBT) is urgently needed as a raw material for the manufacture of electronics, military, shipping, medical devices to household appliances. The need for PBT increases along with the increase in the capacity of plastic food and …
Vinil Acetate is the simplest ether compound in the form of a colorless gas. Vinil Acetate has similar properties to Liquefied Petroleum Gas (LPG) so it can be used as a new energy source. The main raw materials for the manufacture of Vinil Acetate are Ethylene, Acetic Acid and Oxygen. The process used in the dimevinil acetate plant is an acetic acid gas process because it produces high yield a…
ABSTRACT In aquaculture activities, it is important to pay attention to water quality because water is the main medium for fish survival. The quality of the water used must meet the requirements needed for fish life, both in quantity and quality. One of the important aspects of water quality parameters is pH and dissolved oxygen concentration. The pH balance in the pond greatly affects the gro…
Abstract As the demands for electrical energy sources in Indonesia increases, the Indonesian government calls for developing electrical energy sources through the provision of renewable alternative energy power plants which have enormous potential, to be developed in Indonesia. Among them are solar power plants, which are realized using solar cells. An alternative power plant in the form of a …
ABSTRAK The fuels which is often used in steam power plant come from limited fpssil fuels. The limited fossil fuels forces us to fins another alternative fuels. One of alternative fuels which is used in steam power plant is biomass. Coconut coir is biomass which has potential to become alternative fuels. Availability of coconut coir in Pulau Burung is over supply. This paper aims to calculate …
ABSTRACT Solar panels have low efficiency because they cannot fully convert solar energy into electrical energy, coupled with the surrounding environmental conditions with erratic weather which also affects the output of solar panels to be unregulated or constant. The purpose of this research is to produce a design tool for a regulated dc buck boost converter power supply 24 V ± 5% of solar c…
