Abstract

Environmental management in industrial estate is the strategic policy model which is needed to be developed referring to the Indonesian Government Decree number 24 year 2009, that state almost all of the new industrial developments should be located in industrial estate. The complexity in this environmental management was approached by “green rating” of PROPER’s criteria regulated by Ministry of Environment & Forestry (KLHK). PROPER is the assessment program of company performance rating in environmental management. Green rating is classified by PROPER in terms of beyond compliance performance. The result of the case study in Jababeka Industrial Estate (KIJA) Bekasi, based on its environmental situational analysis year 2014 by multidimensional scaling (MDS) method, showed that only the management dimension had a sustainability performance. The results of prospective analysis on leverage factors of MDS showed that the key factors of the environmental management model were (1) DRKPL (summary document of environmental management performance), (2) implementation of water conservation and reducing water pollution program, (3)funding for water conservation, (4) monitoring and evaluation of community development program, (5) implementation of 3R (reduce, reuse, recycle) programs of hazardous waste, (6) technology of 3R, and (7) benchmarking. Based on the key parameters and referred to the possibilities conditions, three scenarios have been developed to approach the implementative policy. The moderate scenario was recommended to be the right policy in term of consideration of technology, funding availability, time of implementation and organization skills.Keywords: environmental management, industrial estate, jababeka, proper KLHK

Abstract

Dioxin/furan is one of the persistent organic pollutants (POPs) that the government and public in Indonesia has not taken care of, as there is currently no policy on reducing dioxin/furan emission, even according to previous research dioxin/furan emission has already high. Steel industries produce dioxin/furan emission that will give negative impact to the people (cancer and death) and environment. The objective of this research was to estimate dioxin/furan emission and to determine factors that influence dioxin/furan emission concentration on the air, especially from steels industries. Methods employed in this research used emission factors to estimate dioxin/furan emission and Gaussian dispersion modeling to estimate emission concentration. The result showed that dioxin/furan emission is 9,38-13,54 gTEQ and it has to be reduced. Production is main factor to contribute dioxin/furan emission to the air. Besides that, emission concentration also depends on temperature, wind speed, height of stacks and radius from the site to the recipient. The conclusion of the research is dioxin/furan emission should be reduced, by means of first or second treatment.

Abstract

It is estimated that the increase of sugarcane production will also increase the amount of bagasse. Sugar mills utilize dried bagasse as boiler fuel and the burning results a bagasse ash.Unrefined bagasse is estimated to contribute to the impact of the environment, including health problems when inhaled by humans. When covers the leaves, it will block the process of photosynthesis in plant. This are due to the size of ash and the contents of silica dioxide compound inside the bagasse. Besides providing impact, silica dioxide compounds are compounds that have high economic value as it can be used as silicon. The purposes of the utilization of bagasse ashes into silicon are to reduce the impact on the environment, to increase the economic value of bagasse ash and to empower community. The results of the feasibility analysis of silicon production from bagasse ash arethe planned production capacity of 10,000 tons/year, breakeven point (BEP) that is 3,400 tons/year or 34% of production capacity, Return of Investment (ROI) that is 28%, Payout Time (POT) of 3,6 years and 28,25% of Internal Rate of Return (IRR).Therefore, the plan to utilize the bagasse ash from silicon can be considered to be done.

Abstract

Metal coating wastes generally bring about environmental health problems resulting from liquid wastes that contain heavy metals. The waste processing carried out thus far does not solve the problems because it just move wastes to other media. Cleaner production comes to be an alternative in minimizing liquid wastes, for water consumption, and for raw material. The present research was intended to identify wastewater resulting from the production stage, get cleaner production opportunities that can be applied, and give priority to clean production opportunities. The research stages began with a quick scan to identify the sources of wastes in production process and to determine an alternative of cleaner production chance, and then an economic computation was done, including B/C ratio and payback period. The determination of the priority of cleaner production technique given to a company was conducted by using exponential comparison method. The results showed that liquid wastes were originated from the process of fat removing, metal coating and process of cleaning up the remaining oxides. Liquid waste or loss in the form of contaminated fat solvents, the quite great loss of water due to evaporation and leakage. Cleaner production opportunities that can be applied by modifying/adding tools so as to prevent alkali solutionfrom being contaminated, reducing evaporation and reducing leakages by good housekepping. Three opportunities for cleaner production obtained to have B/C Ratio of more than 1 is can be implemented. Based on the exponential comparison method, the main priority of cleaner production is found, that is pipe changes in the residual oxide cleaning process to avoid leakage, technically and operationally the easiest to implement and followed successively with modifiying/adding tools to process of fat removing and metal coating.
