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…
ABSTRACT Eucalyptus hybrid oil is one oil that is widely used in the cosmetic, pharmaceutical, food and beverage industries. Currently, there is no research on the extraction of essential oils from hybrid Eucalyptus leaves using ultrasound equipment. In this study, the extraction of essential oil from hybrid Eucalyptus leaves was carried out using an ultrasound device in order to speed up the …
ABSTRACT Used cooking oil is frying oil that contains carcinogenic compounds such as free fatty acids, peroxides and others. To reduce the risk due to the impact of used cooking oil, researchers are interested in recycling used cooking oil by carrying out a purification process using cassava peel charcoal as an adsorbent. This study aims to determine the effect of the size and mass of cassava …

ABSTRACT Kerosene has recently been scarce and the price is relatively expensive, therefore this study aims to find alternative fuels to replace kerosene for stoves with stoves, namely fuel from a mixture of used cooking oil and spiritus. In order to get the best performance of the burner stove that is fueled by a mixture of used cooking oil and spirit, the variation of the ratio of the used co…
ABSTRACT Adsorption is a separation process in which certain components in the fluid phase move to the surface of a solid which has absorbing properties. Active kabon is made from durian skin. Durian skin is a waste that can pollute the environment. One of the efforts to increase the economic value of durian skin can be done by processing it into activated carbon. This study aims to determine …
ABSTRACT Rubber seeds have a high nutritional content, the nutritional content contained in rubber seeds is the content of protein, fat and carbohydrates, therefore it has the potential to be processed into flour and also rubber seeds have a fairly high content of cyanide acid (HCN), the presence of cyanide acid (HCN) is high, so rubber seeds are rarely processed into food. This study aims…
