We have successfully prepared porous carbon from water hyacinth plants using several steps, i.e., carbonization, activation, and calcination processes. Water is an alternative as a material due to the ease low cost of manufacturing process, abundant raw materials in nature, its contribution solving environmental problems. Utilization weed for will provide added value hyacinth. In this research,...

Ethiopia has a large biomass of water hyacinth (Eichhorniacrassipes) in Lake Koka and LakeTana during the summer season. Local community doesn’t use this hyacinth. So activity is designed to produce biodiesel from determine its quality parameters. This should be based on concept renewable energy discard lake. The Specific gravity (g/ml), Acid value (mgKOH/g), Water content (mg/g), kinema...

Agricultural practices can result in differences in organic matter (OM) and agricultural chemical inputs in adjacent ditches, but its indirect effects on OM composition and its inherent consequences for ecosystem functioning remain uncertain. This study determined the effect of agricultural practices (dairy farm grasslands and hyacinth bulb fields) on OM degradation by microorganisms and invert...

Abstract Urea-based multi-coated slow release fertilizer was produced using water hyacinth, humic substances, and chitosan, with rich in natural organic matter as a solvent. Elemental analysis showed that the nitrogen content of (FERT) around 20%. Swelling tests demonstrated effectiveness hyacinth crosslinker, which reduced permeability material. Leaching FERT released very low concentration am...

Water hyacinth (Eichhornia crassipes) has become a threat to many aquatic environments worldwide. This weed presents rapid reproductive capacity and outcompetes other plant species, forming dense, free-floating mats, which in instances completely cover fresh-water surfaces. The infestation leads several serious environmental (including ecological socioeconomic) impacts that are hazardous system...

Shallots (Allium ascalonicum L) is an important vegetable plant as a kitchen spice. and traditional medicine. The productivity of shallots in Riau still low, due to low soil fertility. For this reason, fertilization carried out by combining liquid organic fertilizer with water hyacinth potassium nitrate (KNO3).
 aim study was determine the main interaction influence POC Water Hyacinth KNO3...
