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

The ability of East Manggarai Regency to meet the electricity needs of the region is estimated at only 44.91%. This metter is caused by natural conditions that have a dry climate and critical land, making it difficult to can improve of community economy and generaly region for development of adequate electricity. Therefore, the electrical energi need has been to development challenge, while fossil energi untenable. The construction of a biomass from the Gamal (Gliricidia sepium) plant is a potential alternative to develop. This research aimed to identify the potential lands for Gamal and predict the electricity potency. The method was image analysis from Citra TM 8 using GIS Version 10.1 as an analysis tool. Collecting data was through community interviews with purposive sampling method. The results of this study described the degraded land areas of 187.462,01 hectares which are the potential land for Gamal planting. Prediction of critical lands could produce 98 181.76 m3 of wood products and generate 18.90 MW / year of electricity.

Abstract

PT. YMI is one of the automotive manufacturers for two-wheeled vehicles. As a part of the Astra Group, the company strives to become a "Green Company" through the AGC (Astra Green Company) program. One of its assessments is a 30% wastewater recycle program per month which aims to save or use clean water efficiently. The technology used for purification of effluent water from waste water treatment is by Reverse Osmosis technology with initial treatment by using Cation Resin, Activated Carbon and Micro-filtration process. The membrane used for this Reverse Osmosis system is the Filmtec 30-4040 TW / BW. The result of the application of Reverse Osmosis technology to clean water usage in PT. YMI is 34.99% which this success can be achieved due to the recycling of effluent water contributing 100%. In addition, there are also benefits obtained from the absence of effluent water into the industrial estate. Income fee earned amounted to Rp 23,591,675, - / month. For expenses (electricity usage, spare part and overtime) Rp 11.470.172, - / month so the profit earned is Rp 12.121.503, - / month. Payback Period for this R.O. system will be achieved for 24 months or 2 years.

Abstract

Kecamatan Selat Nasik is one of the subdistricts in Belitung Regency with limited avaliability of clean water. It is because the district located in the archipelago with limited clean water sources. The purpose of this study is to determine the potential of clean water. The analysis of this study are: clean water analysis, population growth analysis, and water availability analysis. The final result shows availability of clean water both 466.366 liter per person per day (in 2018) and 519.611 liter per person per day (in 2023). While the necessity of clean water required both 586.260 liter per person per day (in 2018) and 556.470 liter per person per day (in 2023). In other words, the needs of clean water in Kecamatan Nasik until 2023 can not been able to cover necessity of clean water population yet.

Abstract

Abstract:. The key factors which supported to develop sustainaibility in the environmental management in the industrial estate was studied by many approaches. The principles of analysis were elaborated by the multi dimension key factors that affecting the policy of the environmental manager in ecology, economy, social, technology and estate management aspects. This study was initiated by considering and combining the dominant factors which the results of prior researches that using Multi-Dimensional Scaling (MDS) method. The dominants factors were reveiwed by expert judgment approach by Bourgeois matrix as the propective analysis tool. The analysis was focus in the key factors that has low value in the dependence (<1) but has high value in the influence (>1) of the normalized graph of dependence-inluence. The key factors were a) implementation of 3R for hazardous waste; b) industrial wastewater quality; c) industrial estate wastewater quality ;d) labor condition, and e) industrial water demand. The study was analyze that the optimistic scenario can be obtainedby the industrial estate manager by conducting the strategic steps. The initial program was recommended by enforcing the industrial companies to improve their waste water quality and increasing 3R of hazardous waste, that will enhance increasing the waste water quality of the centralized wastewater treatment of industrial estate. The environmental synergy between industrial company and industrial estate management will promote the good labour condition and stakeholders trust for more business opportunities that indicated by increasing industrial water demand.
