Title

Composting system improvement by life cycle assessment approach on community composting of agricultural and agro industrial wastes Aziz, Rizki -; Chevakidagarn, Panalee; Danteravanich, Somtip -

In order to improve a community composting system, three scenarios have set based on the critical points of initial system from sensitivity analysis result of Life Cycle Assessment of community composting system of agricultural and agro industrial wastes composting. Sensitivity analysis of initial system revealed two critical points that used as consideration on setting of improvement system scenarios. On initial system, composting process contributed the highest impact potency on acidification, eutrophication, global warming, and photochemical oxidation, while distribution was responsible for the highest impact on human toxicity potential. By comparison of initial composting system with three improvement scenarios, it found that the third improvement scenario (SC3) was the best scenario that recommended to be implemented. SC3 promoted application of compost blanket for gases emission reduction of compost pile, and substitution diesel fuel of pick-up with CNG fuel for transportation emission reduction. This scenario reduced impact of initial composting system by 29% with the highest impact reduction was on global warming potential by 54%.

Environmental Characteristics of Slum Settlements in Batang Arau Village of Padang City Aziz, Rizki -; Noer, Melinda; Risna, Lisa

In order to comprehend the problems of slums comprehensively, knowledge of the environmental characteristics of slums is needed based on the classification of aspects of facilities, infrastructure, social, economic, and disaster (hazard). This study aims to understand the characteristics of the environment in the form of infrastructure, social, economic, and slum disasters in the Batang Arau Village, Padang City. Primary data were obtained through field observations and interviews with 80 informants, while secondary data obtained from related documents and regulations. The physical condition of the area is that the regularity of residential buildings is only 102 units of households with the level of regularity of buildings, only 0.26%. The level of residential building density of 522.36 units / Ha, with the feasibility of residential buildings, is only 0.76%. Accessibility following technical requirements is only 0.40%. The condition of the drainage network that meets the minimum quality standard is 0.19%. The number of houses served with water facilities for basic needs of 0.58% with the fulfillment of 0.47%. The percentage of family latrines according to technical requirements of 0.41%, and the amount of domestic household waste that is transported at least twice a week is 49%. Socially, the number of people by sex is almost the same, with the distribution of the productive age of the population of 69.32% of the total population, the level of education varies but in general is high school education, and the most dominant ethnic group in this area is the Minangkabau. From an economic aspect, people's income varies, with work predominantly being fishermen and trade/services. This area is located on a hillside, making it prone to landslides, and due to dense houses, this area is also prone to fires.

The Effect of Compost Raw Materials (Market Waste, Yard Waste, and Cow Rumen) to Quality and Quantity of Compost Yommi Dewilda; Rizki Aziz; Hasnureta Hasnureta

This study combines market waste (MW), yard waste (YW) and cow rumen (CR) as raw materials to obtain the optimum C/N ratio of compost raw materials. Composter consists of 6 variations, namely variation 1 (70% MW: 30% YW), variation 2 (60% MW: 20% YW: 20% CR), variation 3 (50% MW: 30% YW: 20% CR), variation 4 (40% MW: 40% YW: 20% CR), variation 5 (30% MW: 50% YW: 20% CR) and variation 6 (20% MW: 60% YW: 20% CR). This study aims to analyze the effect of variations in compost raw material composition so that the most optimum variation is obtained for the composting process. The method used was semi-aerobic composting. The results of observations on compost maturity for temperature, pH, texture, color and odor parameters have met SNI 19-7030-2004 standards with composting time of 12-21 days. The results of compost quality analysis including water content, organic C, nitrogen, C/N ratio, phosphorus, and potassium have not all variations fulfilled the SNI 19-7030-2004 standard, namely the value of the C/N ratio in variation 6 which exceeds the standard. Of the total compost as much as 3 liters, the solid compost yields of 0.5-1.25 liters and liquid compost from 0.05 to 1.5 liters were obtained. Based on the results of scoring on maturity, quality, and compost quantity, the best variation was found in variation 2

One of the main challenges in agricultural practices is the heavy reliance on chemical fertilizers without being balanced by the use of organic fertilizers. This study aims to analyze the maturity, quality, and quantity of compost produced from a mixture of cow dung, garden waste, and market waste using the Takakura Layered Method with EM4 and Local Microorganisms (LMOs) as activators. The LMOs used included LMO A (tuna fish waste, sugarcane bagasse, and pineapple peel) and LMO B (tuna fish waste, banana peel, and vegetable scraps). Composting was conducted in duplicate with seven treatment variations: (A) cow dung with EM4, (B) cow dung with LMO A, (C) cow dung with LMO B, (D) cow dung mixed with garden waste and LMO A, (E) cow dung mixed with garden waste and LMO B, (F) cow dung mixed with garden and market waste with LMO A, and (G) cow dung mixed with garden and market waste with LMO B. The results showed that all treatments met the composting standards. All variations complied with the Indonesian National Standard (SNI 19-7030-2004) in both maturity parameters (pH, temperature, color, texture, odor, and composting duration) and quality parameters (moisture content, C-organic, nitrogen, C/N ratio, phosphorus, and potassium). The compost quantity was reduced by 27–58%. The best result was observed in variation (D1), which consisted of cow dung, garden waste, and LMO A, achieving a score of 39 with a composting time of only 6 days.
