Plants require essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), but their availability in soil is often inefficient due to evaporation, leaching, and binding. Controlled-release fertilizers (CRFs) provide a solution by regulating nutrient release over time. This study evaluates the effects of two coating materials, polyethylene glycol (PEG) and humic acid, on the release patterns of N, P, and K during an 18-week incubation using Inceptisol from Bogor, Indonesia.

- The biggest hurdle for global fisheries recovery is the need to cut fishing efforts and profits in the short term, which many countries are reluctant to do due to political and social pressures.
- By focusing on eliminating illegal, unreported, and unregulated (IUU) fishing, nations can effectively recover their fisheries without these immediate costs.
- For example, Indonesia's strict measures against IUU fishing led to a 25% reduction in fishing effort, resulting in potential increases in both fish catch and profits, showing that reform is possible without hurting local economies.
To reduce the production cost of biodegradable plastics, the fermentation performance of L-lactic acid for a new fermentation medium, fresh cassava roots (FCRs) as a substrate slurried with tofu liquid waste (TLW) as basal medium, was investigated by batch fermentation of Streptococcus bovis. The fermentation properties of the three substrates, namely, FCR, tapioca (cassava starch) and glucose, which were independently mixed with TLW, were compared with those independently mixed with the standard basal medium, trypto-soya broth (TSB). Experiments were conducted at various sugar concentrations of the substrates with CaCO(3) as a neutralizer.
