The use of unprocedural and ineffective intensive synthetic pesticides by farmers in Batu City has become commonplace and is common. An alternative treatment that can be done is to utilize the activity of microorganisms to degrade these pesticides, which is called bioremediation. Preliminary research was conducted to determine the quality of pesticide-contaminated soil by varying the C/N ratio and water content. The main research was carried out by calculating pesticide residues in the soil using the shaker method and then injecting them into Gas Chromatography-Mass Spectrometry (GC-MS). To determine the activity of microorganisms, we isolated microorganisms. The composting temperature is close to room temperature on days 25–28. The decrease in temperature causes the activity of bacteria to decrease. The C/N 30 treatment showed the lowest residue concentration compared to the C/N ratios of 35 and 40. The C/N 30 treatment consisted of soil, cow dung, organic matter residue, and sawdust. The reduction in pesticide residues (99%) was higher than the control and treatment, with a C/N ratio of 40. The variation in the C/N ratio in the bioremediation process affected the rate of degradation of the pesticide. Pesticide residues in the control, C/N 40, C/N 35, and C/N 30, respectively, decreased in concentration during the 28 days of the composting process as follows: 48.3%, 86.2%, 89.7%, and 99.3%. Based on these results, it can be concluded that the C/N 30 treatment had the highest pesticide degradation rate. The results of testing the growth of the population or colony of microorganisms showed that the increase in the number of colonies of microorganisms and the activity of microorganisms was followed by a decrease in pesticide residues. The reduction in pesticide residues at C/N 30 was 98%; this result showed a higher value compared to the control, C/N 40, and C/N 35.

In this study, the environmental impact is determined using the life cycle assessment (LCA) method, on the products and emissions produced as well as the materials used, such as raw materials, chemicals and fuels. Environmental impact assessments were carried out using an endpoint approach using the 2016 recipe method and divided into three main categories including human health, ecosystem quality and resources. In this study, SimaPro 9.4.0.2 and Open LCA 1.11.0 software are used to determine the extent of the environmental impact of the LCA process. In the LCA results, the most important moisture category in the entire ZA II fertilizer production process is resource impact with the “lost fossil” impact category, while the process unit that produces the highest impact value is drying and cooling. The effects seen in this unit are due to the presence of ammonia chemicals from dirt-repellent materials, the resulting ammonia and carbon dioxide emissions, and excessive electricity consumption. Therefore, it is necessary to provide alternative recommended repair programs. Alternative programs that can be used to minimize the impact include: reducing anti-caking doses, using transformers, and combining reducing anti-caking doses & using transformers.

Violces (Viola odorata) is an herbal plant from the Violaceae family and is used in traditional medicine. This is believed to be due to the presence of phytochemical compounds in the Violces plant that provide the pharmacological activity. This study aims to determine the extract yield value and chemical compound groups contained in Violces leaves. The research method consists of four stages, namely extraction, evaporation, yield value calculation, and phytochemical screening. Violces leaf extract was obtained by maceration for 3 days using methanol as the solvent, then filtered and concentrated using a rotary evaporator. The concentrated extract of Violces leaves was then used to calculate the yield value and subjected to phytochemical screening for alkaloids, flavonoids, tannins, saponins, steroids and terpenoids. The method used for the identification of secondary metabolite compounds involve the use of chemical reagents, indicated by color changes, precipitate formation, foam/bubbles, and rings. The results of the study showed a methanol extract yield of Violces leaves of 26,70%. The phytochemical screening test of the methanol extract of Violces leaves revealed the presence of tannins, saponins and steroids.

Livestock manure which is produced every day can be a problem for the environment if not handled properly. Vegetable waste is generally only allowed to accumulate in the market and immediately disposed of in a landfill without further processing, it can pollute the environment and disturb the aesthetics of the environment. Utilization of organic waste as raw material for renewable energy can be a solution. This study aims to determine the C/N ratio, methane gas production and flames produced from biogas production, as well as knowing the ratio of the ratio of substrate composition and the optimum time to produce the best biogas. This study combined Vegetable Waste (VW) and Cow Manure (CM) with ratio of 90:10, 70:30, 50:50, 30:70, 10:90. Variation of fermentation time was carried out for 5 days, 10 days, 15 days, 20 days and 25 days using a 19 liter volume reactor. The results show that the best ratio of substrate composition in biogas production is VW:CM 70:30 with a C/N ratio of 21.39% and produces 93.78% methane gas and produces a blue flame for 102.35 seconds.
