Surfactant production in Indonesia reaches 70,000 tons per year, wh…
ABSTRACT Nitric acid (HNO₃) is a crucial industrial chemical widely used in various sectors, particularly as a raw material for producing ammonium nitrate fertilizers, explosives, and in the metal industry. The increasing demand for nitric acid in Indonesia each year is not aligned with the still limited domestic production capacity, causing Indonesia to rely on imports to meet national need…
ABSTRACT Acetic acid is an essential chemical widely used across various industries. It is utilized in the production of polymers such as polyethylene terephthalate (PET), cellulose acetate, and polyvinyl acetate, as well as in various types of fibers and textiles. In addition, acetic acid serves as an acidity regulator in the food industry, a raw material in chemical industries such as Purifi…
ABSTRACT Hydrogen peroxide is widely used as an oxidant, bleaching agent, disinfectant, polymer initiator, and cross-linker in various fields, such as papermaking, textiles, chemical synthesis, military, electronics, food, pharmaceuticals, cosmetics, environmental protection, and metallurgy. Hydrogen peroxide production in Indonesia reaches 110,000 tons per year, which is insufficient to meet …
ABSTRACT Phthalic anhydride (C8H4O3) is a chemical used in the manufacture of plastics and polymers. One of its main applications is as a raw material for the production of plasticizers, unsaturated polyester resins, alkyd resins, and other derivative products. Indonesia's phthalic anhydride needs are met by PT Petrowidada in Gresik, Indonesia, with a production capacity of 70,000 tons/yea…
Anandathov Kiswara ABSTRACT Caprolactam is an organic compound with the chemical formula (C6H11NO). At room temperature, caprolactam is a white crystalline solid with a distinctive odor. Caprolactam is categorized as an industrial product because it is used in the textile industry as a raw material for the manufacture of nylon-6, which is the starting material for the manufacture of synthetic…
ABSTRACT High-density polyethylene(HDPE)is apolymer producedof repeatingethylenemonomer units with the chemical formula (C2H4)n. HDPE is produced through the polymerization process of ethylene, 1-butene, hydrogen, a Ziegler-Natta catalyst, and the addition of hexane as a solvent. Demand for HDPE in Indonesia continues to increase, but local HDPE production is insufficient to meet domestic dema…

ABSTRACT The high dependence on fossil fuels has encouraged the Ministry of Energy and Mineral Resources (ESDM) to develop environmentally friendly fuels. In addition to implementing the use of fuel from a mixture of diesel and fatty acid methyl ester (FAME) of 30 percent (B-30), the government is also encouraging the development of green diesel with crude palm oil (CPO) as its raw material. C…
ABSTRACT Hexamine (C6H12N4) is a strategic chemical that is widely used in the production of resins, explosives, pharmaceuticals, textiles, and various national downstream industries. The continuously increasing domestic demand is still dominated by imported products, so the establishment of a hexamine plant in Indonesia is very important to reduce import dependence as well as to strengthen th…
Biodiesel is an alternative fuel derived from renewable resources such as vegetable oils and animal fats. Its quality is highly influenced by the composition of its fatty acids, which include saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). A high PUFA content can reduce the oxidative stability of biodiesel and accelerate degradation d…
In Indonesia, the incidence of bone fractures in 2018 reached approximately nine million cases, with various types and causes. Hydroxyapatite (Ca₁₀(PO₄)₆(OH)₂ or HAp) is one of the bioceramics commonly used in biomedical applications due to its biocompatible and osteoconductive properties, allowing it to integrate well with bone. This study aims to determine the time required for…
Palm Kernel Expeller (PKE), a by-product of palm oil milling, is a lignocellulosic biomass with high potential as a renewable energy source. However, the direct pyrolysis of PKE often yields bio-oil with poor fuel properties due to its high oxygen content, necessitating catalytic upgrading strategies. This study aims to optimize the yield and energy quality of bio-oil derived from the catalyti…
ABSTRACT Oyster mushroom baglog waste that is not utilized properly will cause problems such as environmental pollution and can also be a source of pollution for cultivated oyster mushrooms. Making biobriquettes from mushroom baglog waste is an alternative for managing oyster mushroom baglog waste. However, the briquettes produced must also be of good quality based on SNI 01-6235-2000. Therefo…
ABSTRACT Empty oil palm bunches are lignocellulose biomass waste that has great potential as an alternative fuel. This study aims to evaluate the quality of charcoal briquettes from empty oil palm bunches with variations in the type and concentration of natural adhesives, namely starch and molasses, at concentrations of 7%, 8%, and 9%, respectively. The parameters tested included moisture cont…
