Mixed sludge generated from wastewater treatment plant increases annually.Organic content as COD of the mixed sludge is about 20.000mg/l, which isconsidered to be high-strength wastewater. Due to the sludge have high watercontent, it cannot self-burn. In addition, in many industries, there is not enoughland for landfill. For this reason, an experiment of anaerobic treatment wasconducted to investigate the degradation of organic materials in the mixedsludge. The result shows that high degradation efficiency of organic sludge of 90, 70 and 50% was achieved at organic loading rate of 0,7; 1,4 and 2,1 g/l/drespectively. The degradation efficiency decreased drastically when the organicloading rate increased up to 2.8 g/l/d. During the experiment, gas evolution ratewas low due to low organic content of the sludge.

Urban and regional development needs space and land which then replaces the existence of natural space. The loss of natural space does not give negative impacts as long as it does not exceed ecological carrying capacity.Unfortunately, urban and regional development in Indonesia is dominated by economy motivation than ecology consideration. As a result, several natural disasters occurred such as flood, ground water depletion, land slides etc. Our research objective is to analyze land cover change from natural space to human activity space and several factors which cause it at 4 different regions: Malang Municipal, Batam Municipal, Pemalang Regency and Muaro Jambi Regency. Research result could be used as basic information for local government to arrange planning, use and control spatial change in each area. This research was conducted by using two different time data images with interval 10 years to get land cover change on each region and social economy data from National Statistic Bureau. The model was formulated by using forward stepwise multiple regressions and the result showed that each region has different factors which increase land cover change of natural space such as: (1) Malang Municipal was dominantly influenced by urban sprawl phenomenon, (2) Batam Municipal wasdominantly influenced by government policy to develop industry, (3) Pemalang Regency was dominantly influenced by appearance of several new growth poles, and (4) Muaro Jambi Regency was dominantly influenced by land necessity for agriculture activities.

Chlorine is a chemical substance, which has been used in many industriesfor a long time, especially in the pulp and paper industry and drinking watertreatment. Chlorine has been used in making dye, medicine, plastic, solvent and dry clean. In the sector of energy and electricity, chlorine is used in the cooling water system. Due to the lack of condition of chlorine’s storage, it will lead to the leakage of chlorine gas, which will endanger environment and health. Waste from industrial activity containing chlorine has a potential to damage environment. Chlorine also can easily react with many compounds because of its character as a strong oxidator. If chlorine and organic compounds are bound to each other, they will cause carcinogenic effect. Based on the consideration of the danger of chlorine on environment and health, many countries in the world strive to reduce its use in industries. Many alternatives and technologies have been developed to alternate the function of the chlorine.

Cities percieved having strategic role for implementing global program onsustainable development as established through Earth Summit at Rio de Janeiro by 1992. It is realized that cities are fundamental for economic opportunities and social interaction, as well as cultural and spiritual enrichment. However, cities also damage the natural environment and exploit natural resources in an unsustainable manner, which can jeopardize long-term prosperity and social wellbeing. This is of global concern, as more than half of the world’s population lives in cities and trends indicate that this will increase. Based on this understanding by 1994 European cities declared Aalborg principles and by 2002 several cities of the world declared Melbourne principles on sustainable cities. The principles are intended to guide thinking and provide a strategic framework for action and allow cities to develop sustainable solutions that are relevant to their particular circumstances. Despite there were Indonesian cities participate in Melbourne conference, sustainable cities is still aliens for most of city governance. Therefor there was initiative to formulate sustainable cities principles that assumed more relevance and appropriate to Indonesian situation.

Regional Spatial Planning (RTRW) of a city or a region becomesimportant due to limitation of land, while land necessity is increasing. Inorder to achive the sustainable city / region, the attention to naturalcapabilities on water conservation and flood protection should be adaptedon RTRW. The RTRW should prevent the exsisting capabilities andincrease when the capabilitis are less. Using simulation of model as tool of analysis in the spatial planningprocess, we can see the city/ region capabilities on water conservation andflood protection, and then make decision on spatial use of the city / region.The simulation in this study was applied in the City of Batam, which wasfocused in Batam Island by using data on the year of 2000. The results ofthe simulation shows that regions which are categorized as having high andvery high capabilities on water conservation occupied only 13,36%, whilethose that have high and very high capabilities on flood protection is about23,75% of the island area. By applying of reboisation scenarios, theregions that have high and very high capabilities on water conservation canbe increased to become 56,97% and those that have high and very highcapabilities on flood protection increase to 53.58% of the island area.

According to PDAM survey in Jakarta, Surabaya and other cities, surfacewater resources didn’t meet standard quality anymore for raw drinking water.Synthetic detergents, mostly anionic detergents have been widely used inIndonesia over past three decades, similar to its use in other developing countries, and residuals from such use have entered the country's riverine and estuarine systems. Detergent and other organic substance problems have become more seriuos especially in urban areas where the spread of sewerage systems are still low. According to this reason, it is important to develop low-cost technology to solve this problem such as developing biological treatment for removing detergents and organics.The present study describes the removal detergents and organic matter inriver water using submerged fixed bed biofilter with honeycomb tube plastic media. The experiments were operated by submerged fixed bed biofilter reactor using honeycomb plastic media continuously with size 21 cm x 30 cm x 59 cm, the total volume 372 litters. Results of experiments showed that using this method the removal efficiency of organic matter were affected by hydraulic retention time in reactor. The best conditions are achieved in aerobic tretment (Hydrolic retention time 4 hours) with the removal efficiency were 68,702% for organic materials,and 71,85% for detergent respectively.

The pattern of the land, natural resources and environment used will influence the sustainability of a city. Nowadays, many cities in Indonesia have been developed without consideration of ecological aspects. The development of built areas that tends to be sprawling and convert natural environments such as forests and other green areas, wetlands, and lakes that have ecological functions has been causing the increasing environmental problems such as floods, groundwater shortage, and micro climate change in many cities. Spatial planning that considers thesustainability of ecological functions is a strategic tool to manage the city’s land allocation so as to achieve sustainable cities. However, most spatial planning products of cities have been made without the support of ecological data and analysis in the planning process. The paper discusses the importance of maintaining the ecological spaces as a part of an urban ecosystem and decribes the concept of sustainable spatial planning, including data and analysis should be prepared in order to integrate ecological consideration in the sustainable spatial planning process.

Modern life and modern technology require vast use of energy. The use ofenergy in the cities has been dramatically escalated within the last decades. Since most of energy consumed by people live in urban areas is from the non-renewable resources like fossil fuels, we will certainly face problems of energy crisis and global warming to sustain our cities livable in the future. Due to the moderate prevailing climate conditions, which are close to the comfort temperature, less energy will be required to modify indoor temperature suitable for human indoor activities. Since the dependency to the energy is small, people in the humid tropic may have better chances to sustain their cities livable in the future. However, most of Indonesian cities are designed in such away with little consideration to some important design factors as climate, environment, energy, green transportation and an adequate infra structure, like urban drainage. In return, many cities are nothealthy and convinience to be lived for and are not in line with the sustainable design approach. This article provides some discussion on how tropical cities in Indonesia must be planned and designed toward sustainable built environment. Energy as the main role in sustaining our built environment is taken as a priority here to be considered in designing our humid tropical cities of Indonesia. This is in order to achieve sustainable living environment for our future generation and us.

The growth of the oil palm industry in Indonesia has been phenomenal. With only 106.000 ha planted in 1968, it has increased to more than 3,393 million ha in 2000. Fertilizer has played a major role in contributing to the advancement of sustainable oil palm yields. Currently with Asian economies experiencing an economic slow down and locally with the depreciation of rupiah, fertilizer costs have inevitably gone up causing the increase of production costs. Recently some plantations are trying to use waste water for fertilising purpose since it known that waste water contains some potential nutrient such as N, P, K and Mg. In Sei Manding this usage increases the production up to 27%.

The concept of carrying capacity of water resource is applied as amanagement tool for the operationalization of sustainable regional planning.Carrying capacity of a region, comprising its supportive and assimilativecapacities, is defined as the ability to produce desired outputs from a resourcebase to achieve a higher and more equitable quality of life, while maintainingdesired environmental quality. The proposed conceptual model for thecarrying capacity-based planning process considers problems, constrainingand supporting factors, and interrelated systems within a dynamic ecosystemto arrive at the water resource-based sustainable regional planning.
