Abstract

Cassava peel has high carbon content. It becomes potential as an adsorbent in adsorbing laundry phosphate compounds. Utilization of cassava peel into activated charcoal is an effort to reduce waste from the cassava processing industries. This study used two types of activated carbon from cassava peel, i.e. acid activated charcoal using HCl 0.4 M and alkaline activated charcoal using KOH 0.4 M. The objectives of this research were to determine: (1) the optimum contact time of adsorption at 30, 60, 90, 120, 150, and 180 min treatment time; (2) the optimum pH value of adsorption at pH 4, 6, 8, and 10; and (3) the adsorption capacity using adsorbent concentration treatment of 0.5%, 1%, 1.5%, 2%, and 2.5% (w/v). The experimental design used was a Single Factor Randomized Block Trial Design, ANOVA-DNMRT statistical analysis, and linear graphic for descriptive analysis. The analysis of the activated charcoal showed that water contents of the acid activated charcoal and the alkaline activated charcoal were 3.49% and 2.89%, respectively; the ash contents were 6.78% and 9.03%, respectively. The water content and ash content meet the standard of SNI 06-3730-1995. The performance test showed that the optimum contact time and pH of acid activated charcoal were 30 min and pH 4, while the alkaline activated charcoal was 90 min and pH 6. The adsorption capacity of acid active charcoal was 0.26 mg/g and the adsorption capacity of alkaline active charcoal was 0.49 mg/g. Activated carbon from the cassava skin can be used as an adsorbent to reduce phosphate concentrations in laundry waste. Keywords: activated charcoal, adsorption, cassava peel, laundry waste, phosphate

Abstract

The drying performance technology is one of the most critical operations in copra production. This study aims to identify various drying methods in copra production and determine the best copra drying method based on the criteria of drying operation, environmental impact, and copra product quality. The research was carried out with the stage of identifying the drying methods of copra through literature studies and secondary data collection and continued with the stage of determining the best drying method using the composite performance index (CPI) method. Of nine drying methods, six range were identified as coconut processing scale 20–1200 kg, copra drying temperature 40–70°C, drying time 7.9-48 hours, drying rate 1.05–5.70%/hour, energy use 110.7–32140 kJ/kg-product, and the emission of 0.1–34.074 kg-CO2/kg-product. The nine methods of drying copra produce good quality copra based on copra product standards. Based on the calculation of alternative values using the CPI method, it has been shown that the best drying method was using a dryer with a drying temperature of 68°C and a drying rate of 5.70 %/hour. This drying method uses the energy of 14824 kJ/kg product and produces an emission value of 1.25 kg-CO2/kg product. The copra produced by this drying method gives 5% moisture, 60% oil, and 1% free fatty acid. Keywords: coconut, composite performance index, copra, drying technology

Abstract

Waste minimisation in paper industry activities can be done by applying cleaner production methods. The objective of this research was to study of opportunity of cleaner production implementation in sack kraft industry. These stages of research were identification of process stages, identification of problems, identification of cleaner production opportunities, feasibility analysis of technical, environmental and financial aspects, and election priority cleaner production opportunities with Exponential Comparison Method (ECM). The processes of the sack kraft production included stock preparation, sheet formation, pressing section, drying section, scrolling and cutting. These Sack Kraft Industry used 110 tonnes of cardboard afval and produced 90.742 tonnes of sack kraft, 3.65 tonnes failed paper, 2.443 tonnes scattered paper, 4.915 tonnes defected paper and 8.25 tonnes solid waste in the form of plastic and metal. The problems often had been occured were downtime machine, broken machine, solid waste production, failed paper, scattered paper, and defected paper. Recommendation of cleaner production opportunities were making pellets from solid waste as fuel substitution (PBP 0.1 years and B/C 8.31), application of Standard Operating Procedure (SOP) for machine maintenance (PBP 3.9 years and B/C 1.3), Good manufacturing practice training (PBP 0.63 years and B/C 2.58). The priority order of cleaner production using ECM was application of SOP for machine maintenance, GMP training, and making pellets as fuel substitution. Keywords: cleaner production, sack kraft, paper industry, exponential comparison method

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
