Abstract

Since Indonesia have signed and ratified Stockholm Convention on Persistent Organic Pollutants (POPs) in 2009, the country must make efforts to manage POPs appropriately. A number of pollution evident of POPs has occurred in Indonesia, either air, soil or water. Agricultural soils are not excluded from POPs pollution as the result of halogenated pesticide uses or other unidentified sources. Contamination of POPs to humans have been detected, as well as indicated potential exposure of POPs to humans. Based-catalyzed decomposition is a method that can be used to decompose or decontaminate POPs. Limestone can be processed to produce calcium-based catalyst that can apply for POPs decomposition. Indonesia is a country rich in limestone natural resources to produce calcium. However, calcium is inferior to sodium or potassium in reactivity for the dehalogenation of POPs. Thus, more evaluation is needed in order for synthesizing proper and economical calcium-based catalyst to alleviate POPs pollution in Indonesia.

Abstract

PT YZ is a palm oil industry that has a processing capacity of 60 tons of FFB/hour with its main products in the form of Palm Oil (CPO) and Kernel. The palm oil industry in addition to producing the main product in the form of CPO, also produces a large amount of waste. The waste consists of solid waste, liquid waste and gas waste. The purpose of this research is to identify the flow of materials, products, and non-products in the production process of the palm oil processing industry and waste treatment processes, identify cleaner production alternatives that can be applied to the palm oil industry and determine the priority scale of cleaner production opportunities in the palm oil processing industry. The methods used include literature study, observation, mass balance analysis, technical feasibility analysis, economics (B/C and PBP), environmental, and Exponential Comparison Method (MPE). PT YZ has handled it by reusing the waste formed as boiler fuel (solid waste) and land application (treated liquid waste), but there were still waste and loss problems. The strategy for implementing cleaner production that technically, economically and environmentally feasible were 1) Modification of the process by adding a reservoir for condensate water and oil, with B/C value = 2.5 and PBP = 0.50 years, 2) Application of good housekeeping by reducing dirt on fruit with GMP (good manufacturing practice) training, with B/C value = 1.61 and PBP = 1.63 years, 3) Application of good housekeeping by controlling or supervising the use of water by adding a water meter in each unit of process and repair of leaking pipes, with B/C value = 2.16 and PBP = 4.31 years and 4) The application of good housekeeping by reducing oil spills in the digester by repairing leaks in the digester tank and pipe, with B/C value = 1.48 and PBP 6.30 years. Based on the score obtained, it shows that the implementation of good housekeeping by reducing oil spills in the digester is the main priority. Keyword: cleaner production; MPE; palm oil

Abstract

Charcoal is a coconut derivative product produced from burning coconut shells. In this study, coconut shell charcoal was obtained from the by-product of copra processing. The processing of coconut shell charcoal produces emissions that pollute the environment, which are greenhouse gas (GHG) emissions equivalent to CO2-eq. Life cycle assessment (LCA) is a method that can assess the environmental impact of a product throughout its life cycle. Net energy calculation was carried out to determine the energy efficiency of charcoal production in the form of net energy value (NEV) and net energy ratio (NER). The LCA studied was gate-to-gate, namely from coconut shell transportation to processing into charcoal with emission function units per 1 kg of coconut shell charcoal product. The study was conducted at CV X, located in Sukabumi, West Java, Indonesia. The calculation results show that the raw material transportation stage produced 0.0626 kg CO2-eq/kg charcoal, while the pyrolysis stage produced 0.212 kg CO2-eq/kg charcoal. Energy efficiency analysis showed NEV 9,398.66 MJ and NER 1.09. Recommendations for improvement that can be given are to produce charcoal in one place with a copra factory and produce liquid smoke from the combustion of charcoal. Charcoal production in one factory with a copra factory could reduce the GHG impact by 48%, increase NEV to 12,823.19 MJ, and increase NER to 1.13. Utilization of smoke into liquid smoke increased NEV and NEV to 107,715.75 MJ and 2.03. Combining the two scenarios increased NEV and NER to 211,856.62 MJ and 2.10. Keywords: coconut shell charcoal, life cycle assessment, net energy ratio, net energy value

Abstract

The health belief model is used as a framework to identify factors that influence the risk of pesticide poisoning. Research on the factors that influence knowledge and behavior to reduce pesticide exposure using the Health Belief Model and the Structural Equation Model – Least Square has been conducted. This study aims to analyze the effect of the health belief model in predicting behavior to reduce the health impact of pesticides. This type of research is an analytic observation with a cross-sectional design. Structural Equation Model – Least Square is partly an approach used to determine latent variables with bootstrap parameter estimation. The results showed that all latent variables had an effect on farmers' self-efficacy. Increasing the farmer's self-efficacy by 1% can reduce the level of poisoning by 81.3%. Farmers must be able to increase their self-efficacy regarding the risk of pesticide exposure and implement safe pesticide use procedures.  Abstrak: Model kepercayaan kesehatan digunakan sebagai kerangka kerja untuk mengidentifikasi faktor-faktor yang mempengaruhi risiko keracunan pestisida.
