Ecological studies on the Durian (Durio spp.) in Intuh Lingau District, East Kalimantan Province was conducted on December 2005. One plot (0,6 ha) was establised at durian habitat for vegetation analysis. As the result, the forest type is secondary forest. Total number of trees (Stem diameter > 10 cm) were 183 individu which dominated by Durio zibethinus, Macaranga triloba, Ficus variegata, Octomeles sumatrana and Strombosia javanica. While, total number of sapling (stem diameter 2-9,9 cm) were 287 individu/0,15 ha which dominated by Leea rubra, Saurauia nudiflora, Monocarpia marginalis and Bridelia glauca. Vegetation structure and composition at study site will also discussed.

The objective of this study is to understand the performance of microbial degradation activities in textile wastewater treatment unit. Result of BOD, COD, DO and microbial measurement indicated that DO concentration in activated sludge wastewater treatment unit was < 0.5 mg/L, ratio of BOD and COD was >1.99 and microbial density was around 1 x 107 ind/mL. Based on parameter measured, firstly, the DO concentration is not enough for biodegradation process but this condition still work for biofloculation process; secondly, the BOD and COD ratio is indicating that wastewater compound could not fully degrade, eventhough the microbial density in the wastewater unit is in normal number.

Eceng gondok (Eichornia crassipes (Mart)(Solms) is a floating plants that creates problems on the maximum of waters utilization. On the other side, eceng gondok is a potential organic matter that can be used for a growing media. The utilization of the organic matter for growing media will support of organic farming and minimize the use of chemical materials. Process of eceng gondok decomposition can produce a growing media with high nutrients contain for plants growth. The experiments of growing media from eceng gondok for sawi hibrid plants show positive respons in which the plant has freshly growth and free of diseases.

Residential solid waste is being a critical problem in many cities including Jakarta. Community-based management is the most important strategy even when sophisticated treatment such as bio-energy or waste industrial park would be implemented soon, as every waste processing needs separated wastes. Increasing the participation through community-based management is more effective than change people’s perception and behavior on domestic wastes. In some cases, to change community behavior in waste separation and recycling need more than ten years i.e. at Kampong Banjarsari, but with appropriate support system on social planning only took two years i.e. Kampong Rawajati. The implementation constraint of this programme is on replication or expandability of the programme to implemented in another place. There are also lack of government’s significant efforts to push and to support that action. It’s true that some communities develop the same model, but without acceleration and expandable programme, the significance of that effort is very poor. This study tried to ellaborate the model of a system based on spatial analyses to determine residential typology and found five residential types i.e. high,middle-high,middle,middle-lower and lower level of residential, quantitative analyses to determine typology of community participation and found four types of community participation i.e. moral-normative, moral-remunerative, calculative-remuneraive and calculative- coercive. Qualitative analyses had been ellaborated to determine authority or goverment policies typology especially on strengthening the government institution and limiting the scope of government function. Breaking down from these classification, three strategies could develop, namely community participation strategy, infastructure development strategy and institutional management strategy.Implementation of these models could accomodate the heterogeneity ofcommunities and give positive impact on social acceptability.

NATRIUM SILIKAT SEBAGAI BAHAN PENGHAMBAT API AMAN LINGKUNGAN Achmad Hidajat Effendi

This research aims at investigating the effectiveness of fire retardant siliceous based materials which is made of natrium silicate (Na2SiO3.2H2O). Factors related to selection of mixed composition with respect to fire such as the easiness in processing or coating as well as the optimum weight of coating per m2 are investigated. Experimental method is used in this research with equipment used in this experiment include Fire Propagation Test Apparatus (based on JIS A 1321, 1994, # 605). Experiment is done on Borneo and Red Meranti Wood and comparison is done on the result of test undertaken on these types of wood which are treated with siliceous based fire retardant materials. Investigation also reveals that the more natrium silicate absorbed by the wood will increase the temperature rise (td è) and smoke developed index. Experiment on mixture composition of 1 : 1 on both woods has proven it. The best mixture of siliceous based fire retardant against fire while ensuring ease workmanship is under the ratio 7 : 1 up to 10 : 1, with the layer optimum weight per m2 is approximately 0.7 kg. Using this type of fire retardant has proven the increase in the quality ofBorneo wood and Red Meranti wood from quality class 4 (Semi fire retardant) to become quality class 2 (Semi non combustible).

The diffusion of Waste Management System to the society should be followed by the change of not only their knowledge and attitude, but also their behavior. To find out the effects of the diffusion to the society, some measurements can be used. These are the number of society adopted the system and how fast the society can adopt it. In order to measure the success of its implementation, the knowledge on the natures of innovation in waste management technology is required, as well as the components influencing how fast it is adopted. By doing so, the system socialization is expected to be more acceptable by all parties. It is needed to avoid the incompleteness of waste management system socialization carried out so far by society and government elements.

Study on richness diversity plants in Kakenauwe Nature Reserve and Lambusango Game Reserve had been conducted. One hundred and seventy species of Spermatophyta, 12 species of Pteridophyta and 24 species of Bryophyta are collected from this area. One hundred and four species of Spermatophyta and 6 species of Pteridophyta are reported as potential species of plants. The largest group is timber (32 species) and other is ornamental plants (24 species), medicinal plants (17 species) and edible fruits (13 species). This study also reported that Orthorrhynchium phyllogonioides is recorded as “new record” of Bryophyta collections in Sulawesi.

APLIKASI SISTEM FUEL CELL SEBAGAI ENERGI RAMAH LINGKUNGAN DI SEKTOR TRANSPORTASI DAN PEMBANGKIT Achmad Hasan

Fuel cell is a device which is purposed to convert chemical energy into electric energy and produce water as side result. Fuel cell technology doesn’t produce emission and doesn’t make noises and also as environmental friendly energy has a high efficiency until 45% in fuel conversion to electricity, and it can be higher until 60% – 80% if it isco-generation. A fuel processing system converts hydrocarbon or other organic fuels to hydrogen of composition and purity suitable for fuel cell operation. The fuels include petroleum derived liquids, such as naphtha and gasoline, petroleum derived gases, such as methane and propane, and other fuel such as methanol and ethanol. The electrolyte in the center allows only the protons to pass through the membrane to the cathode side of the fuel cell. The electrons cannot pass through this membrane and flow through an external circuit in the form of electric current. As oxygen flows into the fuel cell cathode, another catalyst helps the oxygen, protons, and electrons combine to produce pure water and heat.

One million hectare peat land development project in Central Kalimantan Province has been conducted based on Presidential Instruction, Number 80, 1998 dated June 5, 1995 for Foot Sustainability and followed by Presidential Degree, Number 82, 1995 dated for Development Of Peat Land To Be Utilized As Horticulture Field. The main goal of the project is to convert peat wet land into rice field, in the Central Kalimantan Province. This is also aimed to keep the rice self-support up attained by Indonesia in 1984. This program is in line with the government policy in fulfilling the foot supply, i.e. by extensification of newly open lands, increasing growing intensity to improve food productivity.
