During this time, the remaining milk that has been consumed only wasted. Milk content is strongly associated with nutrients to increase crop productivity. This requires innovations in the manufacture of organic fertilizer products. The purpose of this study was to determine the best composition comparison between stale milk, EM4 solution and cocopeat in the process of making liquid and solid organic fertilizer and determine the c-organic value, Ntotal, P2O5total, K2Ototal, and pH value. Initial analysis of liquid organic fertilizer obtained pH values of 5.10, P2O5total Â of 0.342% and Ntotal of 0.569% at initial control (stale milk only) and final values of 1.010% ofÂ P2O5total, 1.113% of Ntotal and 10.480% of organic carbon in R3 ( 30: 5: 1). Initial analysis of solid organic fertilizer obtained pH values 5.26%, 2.668% P2O5total, 0.952% K2Ototal and 2.780% Ntotal at R1 (10: 5: 1) and final values obtained 1.578% P2O5total at R1 (10: 5: 1) , 2.937% Ntotal in R2 and 43.912% carbon organic in R3. This shows that stale milk with the addition of EM4 and cocopeat solutions has an effect on phosphorus and nitrogen nutrients in liquid and solid organic fertilizer.

Shellfish shells and rice husks can be processed into charcoal and ash. Shellfish ash and rice husk charcoal contain chemical compounds such as pozzolan, lime (CaO), alumina and silica compounds which can replace cement in paving block mixtures. The use of rice husk charcoal and full-blooded clam shell ash as an alternative provides stronger pressure resistance. This research aims to determine the effect of the composition of a mixture of shell ash and rice husk charcoal on the quality of paving blocks. The results of this research were a mixture of composition A3 (2:1) with 66.6 grams of rice husks and 33.3 grams of full-blooded clam shells as well as 500 grams of cement and 1500 grams of sand, resulting in a compressive strength of 14.3 Mpa and was classified as C. Composition A5 (3:1) mixture with 25 grams of rice husks and 75 grams of full-blooded clam shells as well as 500 grams of cement and 1500 grams of sand, produces a compressive strength of 16.7 Mpa and is classified as B. Meanwhile, the composition of the A0 (0:0) mixture without A mixture of rice husks and shells only produces a compressive strength of 9.05 Mpa and is classified as D. The conclusion of the research is that paving blocks of composition A5 show the best water absorption quality with water absorption results of 7.69%.

One of the biomass that can be used for making biogas is fish waste. Based on the research, fish waste has a small c / n ratio so it requires mixing with other organic materials that have a higher c / n ratio. The addition of water hyacinth and cow dung will increase the c / n ratio in the anaerobic process to make biogas. The aim of this research is to analyze the process anaerobically of biogas formation from a mixture of fish waste, cow dung, and water hyacinth. Biogas is made with a variation composition of cow dung (D1), a mixture of cow dung, water hyacinth, and fish waste (D2), and a mixture of cow dung and fish waste (D3).) The Variation ratio of each composition is 1: 0: 0; 5: 1: 1 and 2: 0: 1.

Increased population growth results in increasing human needs over time. Meeting the high needs triggered the development of industries that meet the needs. Problems arise from the many industries that emerge, one of which is an environmental problem. Many industries in Indonesia have not used good waste treatment standards, causing pollution from the rest of the production process in the industry, one of which contains heavy metals such as Pb, Zn, Mercury and so on. Heavy metal is a type of pollutant that is harmful to plants, animals and humans through the process of bioaccumulation in the food chain. The purpose of this research is the content of heavy metals that are harmful to the sustainability of ecosystems in the environment requires a long time so that one way to prevent heavy metal compounds that can be released to the environment is by managing the bioremediasi process with fragrant root medicinal plants (Vetiveria Zizanioides) which has hyperaccumulator properties which can absorb one of the heavy metals namely Cadmium (Cd) and Lead (Pb).

Proper management of company-generated wastewater, specifically wastewater generated from acid correction testing in GCV analysis conducted by service providers and consulting firms, is crucial. Coagulation-flocculation emerges as an effective treatment method, utilizing biocoagulants derived from abundant blood clam and green mussel shells in Cilacap Regency. This study aims to identify the optimal calcination temperature for CaCO3 to CaO decomposition, assess the effectiveness of CaO biocoagulants in treating acid correction testing wastewater, and evaluate the impact of CaO biocoagulant dosage on pH, TDS, TSS, Turbidity, COD, and BOD5 parameters. Results indicate 1000°C as the best calcination temperature, with elemental compositions of Ca at 55.3% for blood clam shells and 58.7% for green mussel shells. The CaO coagulant's efficacy, derived from these shells, demonstrated significant pH increase (5 to 12.10), and substantial reductions in TDS (60%), TSS (79%), Turbidity (91%), BOD5 (93.71%), and COD (88%). The study reveals a dose-dependent relationship, with higher doses elevating pH and decreasing TSS, BOD5, and COD, while lower doses exhibit greater efficacy in reducing TDS and Turbidity values. This research underscores the potential of blood clam and green mussel shell-derived CaO biocoagulants in wastewater treatment, promoting environmental sustainability.
