ABSTRACT Potassium Phosphate (KH2PO4) is one of the few inorganic fertilizers produced locally. This fertilizer consists of the main components of potassium and phosphate where these elements are macronutrients needed by plants. The need for imports of Potassium Phosphate in Indonesia has tended to increase in the last five years. Potassium Phosphate production plants are still minimally estab…
SUMMARY Amylase is a group of enzymes that have the ability to break the glycoside bonds found in starch molecules. Amylase can be produced by several microbes such as Aspergillus sp. LBKURCC304 through a submerged fermentation process. This study aims to optimize the environmental conditions for the growth of Aspergillus sp. LBKURCC304 in produced amylase enzymes. The growth environmental con…

Polypropylene is the raw material for making various kinds of plastic goods with the current market price of 2500-3000 USD/ton. Polypropylene is an important and widely used thermoplastic polymer. The development of various variations and the breadth of its use, it is possible to manipulate …
Chloramphenicol is a broad-spectrum antibiotic with mechanism of action that inhibits protein synthesis and bacteriostatic. The overuse of chloramphenicol produces residues in the environment and cause bacterial resistance. Chloramphenicol can be biologically degraded using white rot fungi. The purpose of this study was to examine the ability of the white rot fungi Phellinus noxius BRB11 and Le…
ABSTRACT Indonesia as a developing country currently is trying to fulfill the needs of various chemicals to accelerate industrialization process. The need for lactic acid in Indonesia is currently still met by imports. Based on BPS 2021 data, total lactic acid imports in 2020 is amounted to 8,308,802 Kg. Therefore, efforts are needed to develop domestic lactic acid production to reduce depende…

SUMMARY Very fine activated charcoal particles were a problem in separating this adsorbent from the solution after the adsorption process, especially for large sample quantities. Magnetic adsorbents were one way to overcome this. In this research, the magnetic adsorbent Fe3O4-activated charcoal was synthesized using palm fronds as a carbon source. Palm fronds are carbonized at 600⁰C for 60 m…
