Abstract

Agriculture is an attempt to establish an artificial ecosystem in charge of providing food for humans. The location of this research was conducted in Tosari Village, Tosari District, Pasuruan Regency. Tosari District is one of the areas located on the slopes of Mount Bromo. This research was conducted for 2 days, starting from October 29 to October 30, 2022. The data used in this study were primary and secondary data. The Tengger indigenous people who live in Tosari Village almost 90% depend on agricultural land for their lives. The geographical condition of the Tengger Tribe which is located in a mountainous area forces them to still be able to utilize the land into agricultural land using a profitable vertical cropping pattern (Larian). Potato is one of the main commodities produced by the local community. In addition, leeks, cabbage, carrots, corn and wheat are also plants that are often planted by the community

Abstract

Vinasse, a highly polluting byproduct generated during ethanol production, exhibited a very high chemical oxygen demand (COD) of 132,000 mg/L, making its treatment a critical environmental challenge. To reduce COD levels in vinasse, the Fenton process was employed in this study. The experiments were carried out for 1 hour in batches at atmospheric pressure and ambient temperature. The chemical reagents used for the reaction consisted of a 50% H₂O₂ solution and Fe(NO₃)₃·9H₂O, with the key variable being the H₂O₂ addition method of direct addition (one-shot, 80 mL at t=0) and stepwise (gradually, 20 mL aliquots at t=0, 10, 20, 30 min). Samples were collected every 10 minutes for COD analysis. While both dosing methods demonstrated time-dependent COD removal, the stepwise addition proved to be significantly more efficient, achieving a maximum measured removal of 57.39% compared to 39.12% for the direct H2O2 addition method. Furthermore, biphasic kinetic modeling showed that the direct addition of H₂O₂ exhibited a rapid initial oxidation phase (k1=0.0925 min⁻¹) followed by a slower and almost stagnant phase (k2=0.0005 min⁻¹). In contrast, the stepwise addition resulted in a lower but more sustained degradation rate (k1=0.0246 min⁻¹; k2≈0 min⁻¹), indicating a more uniform oxidation behavior under stepwise oxidant loading.
