Abstract

In recent years, concerns regarding to wastewater sludge disposal have increased globally. Production of sludge has increased recently due to the growth of population. Wastewater sludge classified as a hazardous substance, it is not easy to dispose because of certain treatment is required. Typically, sludge is treated at secured landfill which its limited in availability and expensive. On the other hand, wastewater sludge originated from biological treatment contains organic substance that can be converted into alternative energy resources. A technology is needed that is able to reduce the volume of sludge and convert sludge into energy source. We present an overview of various technologies that can be used for conversion of sludge into energy resources. Those technologies are anaerobic digestion, pelletization, combustion, pyrolysis and gasification. Progress and challenges of each technology is presented in detail. A summary of sludge characteristic originated from different source will be discussed as well. Emissions and residues that determines the environmental impact is also considered. Referring to some previous research, it known that wastewater sludge, as unwanted product, has the potential to become future energy resource. This potential can only be used properly if the method of conversion are effective and efficient.

Abstract

As the first step to air pollution control and public health protection, Air quality monitoring systems provides information that indicate the extend of pollution in an area, the source of pollution and the types of pollutants. Therefore, the aim of this study is to evaluate Jakarta’s air quality monitoring system by comparing it to the US, which participates in Indonesia’s air quality monitoring system by using their own system.  In specific, parameters such as air quality index, monitoring stations, regulation and data availability are to be compared through reviewing various literatures in detail.  The result obtained shows that the monitoring station amount is already ideal and complies to the U.S regulation. Indonesia’s ambient air quality standard need to be stricter and Air Pollutant Standard Index should include PM2.5 as a parameter obtains significantly better results. Air quality data is available and accessible, although it needs to be integrated and provide real time information in a simple and effective way.

Abstract

The amount of MSMEs units about 99.99 percent of the overall number of business operators in Indonesia showed that MSMEs play a significant role in economic growth and development. At the same time, MSMEs cumulative contribution to environmental issues is not recorded MSMEs participation in the cleaner environment has not yet been noticed. Thus, the environmental management system for MSMes is crucial. This study is a literature review about the implementation of the ISO 14001 environmental management system in MSMEs, challenges and its future potential. The result and discussion discussed the case study of ISO 14001 implementation in Indonesia and other countries. Case studies from Indonesia and other countries showed that implementation of ISO 14001 is possible for MSMEs. The biggest challenges of its implementation is cost, the competence of employees, and resources available for the organization. An alternative for overcoming these challenges is implementing other models of EMS that is more suitable for MSMEs. The important aspects is the environmental awareness of the stakeholders and the internal and external drivers within the organization. Further studies can be done to research specific case studies of EMS such as ISO 14001 or AMEMs implementation in MSMEs.
