Abstract

Durian peel is identified to take a long period of time to decay or degradation, thus it requires a pretreatment to simplify the process of hydrolysis. This study aims to determine the condition of chemical physic composting using cow’s rumen liquor. The study used several concentrations and combinations of treatment. Parameters observed in this study include substrate temperature, moisture content, pH, Total Organic C, Total Organic N, and C/N ratio as well. The results obtained i.e. the average temperature of the substrate is 29,090C, the average moisture content of the substrate is 87.55%, and the average pH of the substrate is 7.82. The percentage change of the Organic C is 0.52% for the treatment of 30%. The percentage change of the Organic N is 36.76%. The Percentage change of C/N ratio is 41.36%. These results indicate a distinctive percentage value from various treatments with the highest concentration at 30% of cow’s rumen liquor on Organic C, Organic N as the control, and C/N ratio as well.

Abstract

This research aims to know the feasibility of financial businesses organic fertilizer from waste cattle beef cattle on small and medium enterprises (SME) Komonitas Natural farmer Village Sidera Subdistrict Sigi Biromaru Sigi Regency based on criteria of Net Present Value (NPV) Net, B/C Ratio, Internal Rate of Return (IRR), Peyback Period (PP) analysis and research Sensivitas. Location determined intentionally (Purposive) with the consideration that SME Produce Natural Komonitas is the only group of farmers who are making business manage organic fertilizer. The respondent's determination was done deliberately (Purposive) with the number of respondents as much as 3 people consisting of 1 Chairman, 1 Treasurer and 1 employee part production. Methods of analysis using financial feasibility analysis, with some indicators that were used i.e. Net Present Value (NPV), the Net Benefit Cost Ratio (Net/B/C), Internal Rate of Return (IRR), Payback period (PP) analysis and Sensitivity calculation of  financial feasibility. Result of organic fertilizer on SME venture Komonitas Natural Farmers are financially viable to run based on the assessment criteria i.e. NPV, IRR, Net B/C and Payback Period, and sensitivity. Organic fertilizer venture acquire the value of NPV is IDR. 25.284.439 Net value, B/C of 3,48, value of 29.31% IRR is greater than the specified level of the discount rate, and PBP are before the project ends i.e. 2 years 9 months 8 days. The results of the sensitivity analysis also showed that organic fertilizers on SME venture Komonitas the Natural Farmer is still worth running and profit despite rising prices of raw materials amounting to 23 percent.
