Isobutylene is an intermediate product that has an important role in various chemical industries. Considering the increasing demand for isobutylene while the isobutylene producers themselves, especially in Indonesia, are still limited, it can be concluded that the market for isobutylene factories is still very open, both domestic and foreign markets. In Indonesia, the product, namely isobut…
Coffee grounds are used as raw material for making biodiesel because the oil content in the seeds is quite high, around 15-25%. Coffee grounds oil was obtained by maceration extraction using n-hexane. As much as 286ml of oil was obtained from the results of the separation with the rotary evaporator. In this study, esterification process was carried out to reduce the water content and high free …
Banana cobs and jackfruit seeds have a high enough starch content that has the potential to be used as raw material for bioethanol production. The purpose of this study was to determine the effect of the combination of a mixture of banana weevil and jackfruit seeds on the glucose concentration resulting from the hydrolysis process and to determine the effect of the mass of the yeast Saccharomyc…

Domestic diphenylamine needs continue to increase, recorded in 2019 according to the Indonesian Central Statistics Agency (2019), which imported 71.463 tons of diphenylamine, which was the highest import compared to previous years. In Indonesia, there is no industry that produces diphenylamine, so there are still many imports from countries such as China, Japan, and America. To reduce the numbe…
Epichlorohydrin is a derivative compound of allyl chloride which has the molecular formula C3H5OCl. Epichlorohydrin is also used in the manufacture of elastomers, glycidyl ethers, cross-linked food starch, surfactants, plasticizers, dyes, pharmaceutical products, oil emulsifiers, lubricants, and adhesives. In Indonesia, the need for epichlorohydrin compounds is still very dependent on impor…
Acetic acid industry in Indonesia is one of the chemical industries that has good prospects. Acetic acid product has a fairly wide market, such as the Purified Terephthalic Acid (PTA) industry, the ethyl acetate industry and the textile industry. Acetic acid, as the main product, manufactured using Acetica process through carbonylation reaction of methanol, with heterogeneous Rhodium catalyst e…

Dimethyl formamide ((CH3)2HCON) or abbreviated DMF is an organic compound in the form of a colorless liquid that can be mixed with water and most organic liquids. DMF has the main function as a solvent with a low evaporation rate. The estimated percentage of DMF consumption in various sectors is acrylic fiber production at 44%, pharmaceutical production at 38%, polyurethane manufacturing at 8% …
Indonesia as a developing country is currently trying to meet the needs of various chemicals to expedite the industrialization process. In fact, until now there are many chemicals that cannot be fulfilled by themselves and must be imported from other countries. One of the industrial raw materials that has not been fulfilled in Indonesia is butadiene compounds. An important use of butadiene is a…
Industrial sector is a very important factor for the nation's economic development. The chemical sector is one area that may be expanded to minimize Indonesia's reliance on foreign industries, lowering foreign exchange expenditures on materials such as benzyl alcohol imports. Benzyl alcohol is a compound that is widely used as a base material or as a supporting material in the manufacture of me…
Ammonia is one of the most widely used materials in human life, such as raw materials for making fertilizers, refrigerants, pharmaceuticals, and others. The main raw materials for ammonia using the KBR (Kellog Braun and Root) process are hydrocarbons and air. The KBR (Kellogg Braun and Root) process is a process with lower energy consumption and higher ammonia purity. This ammonia factory is pl…

In the current era, the world is witnessing a social economic revolution from various types of industries. In Indonesia, the textile industry is growing rapidly along with population growth. However, industrial progress has an impact that is generated in the form of textile waste. One of them is methylene blue, which is a waste that is difficult to degrade by the environment. The AOP (Advanced …
Abstrak In the process of making tofu, wastewater will be produced which has a high protein content and is acidic, so it can cause environmental pollution. One method that can be used to reduce environmental pollution is to use moringa seed coagulants. From these problems, research was carried out on tofu wastewater treatment using Moringa seeds as coagulants. This study aims to study the effe…
ABSTRACT Piles of rice husks have no selling value and become one of the wastes that cause the surrounding environment to be unhealthy, so an appropriate technique for processing rice husk waste is needed. One technique for processing rice husk waste is to process it into activated charcoal. Activated charcoal is widely used as an adsorbent in wastewater treatment to remove various types of he…
