Abstract

Currently, imported electronic products enter the Indonesian market using general import procedures, where the importer has to pay the import duty and taxes in full rate. In the absence of proper recycling systems, the electronic products that have reached their end of life and those are no longer used, end up in the landfills. Some researchers found hazardous materials inside the electronic products that could contaminate water, soil and air. Therefore, another strategy is needed to avoid negative effects on the environment. The Temporary import policy is one of the import procedures under Customs administration control, which states that goods can only be imported for a specific period, and should be re-exported afterwards. This paper tries to analyze the impact of the implementation of the temporary import policy on electronic products. By employing the Input-Output Analysis to the data from the Statistic Central Bureau and Indonesian Customs, this paper identified the impacts of the proposed procedure to some sectors in the Indonesian input-output table, namely: import activity, waste management and recycling system, transportation and storage, and final demand. The result shows increasing in quantity to be re-exported, and potential benefit from transportation and warehousing, leasing and rental services, and other business.

Abstract

Wastewater and household trash have become serious problems in major Indonesian cities due to the lack of environmental education for children and society as a whole. This paper will examine the urban lifestyle and the processing of waste, followed by an analysis of problem-based learning (PBL) experiments in elementary schools in various cities. The analysis will be supplemented with a questionnaire distributed to the students before and after the PBL trial. The article aims to offer an alternative educational environment that will evoke maximum learning results. It has been prepared using cross-tabulation research methods for three groups: The first group is comprised of students and teachers who have studied environmental education using the PBL method and through workshop activities. The second group comprises teachers who have studied environmental education using workshop activities. The third group includes teachers and students who have studied environmental education without the PBL model or workshop activities. Using cross-tabulation, show that the proportion of respondents increased after implementation compared to before is hand both Groups A and B. Group C does not show much change after implementation. From this study, authors conclude that groups using the PBL learning model with workshops showed significant changes in knowledge aspects.

Abstract

Cimahi City is located in West Java Province, Indonesia. With a population of half million and the annual waste generation per capita reaching 0.48 kg/day, managing municipal waste has become increasingly challenging. To date, waste management costs in Cimahi City have not been specifically addressed. In addition to the total cost, there is also a plan to move the final landfill site from TPA Sarimukti, which is located approximately 34 km from the city center to a new final landfill site in TPA Legok Nangka, which is located approximately 56 km from Cimahi Municipality. This move will cause an increase in the cost to Cimahi Municipality. The aim of this study was to analyze the optimum waste management strategies for Cimahi City according to the environmental and cost-benefit impacts of the landfill site move. We used life cycle assessment and cost-benefit analysis to determine the optimum solution for waste management strategies of Cimahi City. Four scenarios, including the addition of waste banks, were compared as municipal waste management strategies. The switch of landfills did not contribute significantly to the total CO2 equivalent emitted. Increasing the number of waste banks could be an alternative to reducing the cost of disposing waste to landfills. Scenario (SC)-2 the scenario with additional government waste banks established, provided the highest net present value equal to IDR 1,428,622 per tonne of waste managed and was considered the most profitable in terms of the cost-benefit ratio. Hence, SC-2 was the most preferred for implementation in Cimahi City.
