Abstract

Indonesia contains about one-third of the world’s total mangroves areas,but experts say more than half of the country’s mangrove forest havebeen destroyed since the 1940s. The main sustainable alternatives tocoastal aquaculture pond development within or associated withmangrove are silvofisheries and mariculture. Silvofishery is a form ofintegrated mangrove tree culture with brackish water aquaculture. Thisintegrated approach to conservation and utilization of the mangroveresource allows for maintaining a relatively high level of integrity in themangrove area while capitalizing on the economic benefits of brackishwater aquaculture. Traditional models of silvofishery is the Empang Paritmodel, which is sometimes reffered to as Tambak Tumpangsari, wasdeveloped in Indonesia, tracing its roots back perhaps over a thousandyears. The modern version of Empang Parit is today being promoted bythe Indonesian Ministry of Foretry and the Directorate General ofFisheries. Silvofisheries have been successfully developed in Indonesiasuch as in Sinjai (Sulawesi), Cikeong (West Java), Pemalang (CentralJava), and Bali.

Abstract

Economically, Rawa Danau is important fresh water source for cities ofCilegon and Serang and industrial estates in the area. Ecologically, RawaDanau is the last and the only mountainous freshwater swamp still exists inJava island. In the last decade there are several studies that recommendincreasing the capacity of Rawa Danau as water storage. Recently, theMaster Plan of Rawa Danau has been published by the Province of BantenPlanning Agency. It is concluded that increasing the water level in RawaDanau by 2 meters would satisfies the 2010 projected water demand inSerang and Cilegon. We belief that the action could endanger theexistence of both the swamp forest and the rice field in the vicinity. In thispaper we describe an alternative action that could increase the waterstorage capacity of Rawa Danau whilst the ecological function of theswamp could be preserved as well.

Abstract

Test were conducted to find the biopotency of pituitary glands that havebeen dry-preserved for 0, 1, 2 3 and 4 months. Pituitary glands, obtainedfrom the waste of fillet production plant of Pangasius pangasius, weredried gradually in acetone. The treatments were dry-preservation timespan in dessicator: 0, 1, 2, 3 and 4 months. This hormone biopotencytesting used extract of late-stage of gonad maturation from female andfrom induced-spawning. No significant differences were found in thepercentage of late-stage gonad maturation and ovulation, relativefecundity, fertility and hatchability from every treatment. The number offemales reaching late-stage of gonad maturation were 100% (for allmonths of preservation), while the mean percentages of : relativefecundity was 18.05% (for 3 months of preservation), fertility was 95.73%(for 1 month of preservation), 24-hour hatchability was 31.63% (for 0month of preservation). No significant differences were found for allpreservation time span.

Abstract

Linear alkylbenzene sulfonate (LAS) represents one of active substanceof surfactants in detergents of which in high concentrations may causeenvironmental pollutions. The aim of the research was to know theefficiency of exclusion of LAS and the rate of LAS degradation indetergent wastes by the anaerobic process at fixed bed reactor equippedwith cross flow material. This research was done in Process Laboratory ofBalai Teknologi Lingkungan BPPT PUSPIPTEK Serpong. Reactoroperation was done through continuous process with close circulation, upflow and 5 hours Rate Time Hour (RTH). Exclusion of LAS of detergentwaste was recorded for 17 days. The degree of acidity after the processwithout inoculum (P1.0) was to 8.45, and for an anaerob condition withadded inoculum (P1.1) was 7.88. The efficiency of the highest exclusionof CO soluble was equal to 80.96% (P1.1) with effluent 476 mg/L, and 76.81 % (P1.0) with effluent 531 mg/L. The exclusion of LAS of detergentwastes was 99.19% (P1.1) with LAS effluent equal to 17.51 mg/L and98.3% (P1.0) with LAS effluent equal to 27.84 mg/L. The maximum rate ofLAS surfactant degradationunt 0.95 ppm/day (P1.1) and 0.44 ppm/day(P1.0).

Abstract

Shrimp culture has became one of the most important Indonesian exportcommodity since 1985 up to the beginning of 1990`s. Due to theincreasing intensification, the pressure on the shrimp ponds environmenthas became a serious problem. The problem was indicated by thedecrease in shrimp production since 1992. Dimethylsulfide (DMS) isknown as a major contributor to total sulfur emission from land and coastalmarine and also known to inhibit nitrification. In this respect, we arestudying the influence of DMS on nitrification process in saline water.This paper describes the DMS concentration observed in several places inthe Western Coast of North Java. The minimum and maximum concentrations observed were 790.32 ηM and 6483.87 ηM respectively. These figures are higher than concentration detected in any other coastal area where shrimp productions are concerned. We speculate that DMS has given some contributions in the depletion of shrimp production.

Abstract

Forest resources are really under pressure nowadays and leave only theconservation areas, although they are already standing on a risky zone ofencroachments and illicit felling. The most important issues to beaddressed in order to enable social forestry and work toward alleviatingpoverty security of land and resource tenure and access, and useplanning, streamlined mechanisms for registering rights and resolvingconflicts.

Abstract

In this experiment, Lemna sp. was exposed to surfactants LAS and ABSand a commercial detergent following method described by OECD. In thetest, 10 fronds of Lemna sp. were grown in a modified MS mediumcontaining the surfactants and detergent in the concentration of 0 ppm to79 ppm and incubated for 7 days under continuous fluorescence lamps.The EC50 values of the detergent and surfactants vary depending on thecompounds and the testing parameter. For LAS and ABS, the value ofEC50 from number of fronds is higher than EC50 from the total chlorophyllcontent, i.e. 14.83 and 14.36 mg/l for LAS and 11.75 and 7.56 mg/l forABS, respectively. However, the total chlorophyll content is not sensitivefor commercial detergent “A” and results in a higher EC50 value of 31.53mg/l. LOEC values for LAS and ABS is 5 mg/l respectively, and is 25 mg/for detergent ”A”.

Abstract

Duriangkang Reservoir including the estuary resevoir is built by makingresevoir at the estuary of Duriangkang River. The main function ofDuriangkang Reservoir is the raw water resources to support 78 % ofdrinking wate supply needs on Batam Island. One of several problem ofDuriangkang eservoir is erosion as a result of land clearing and building ofland at Duriangkang Catchment area. Based on the research,sedimentation rate at Duriangkang Catchment area system is as themayor sources that potentially influence the carrying capacity ofDuriangkang Reservoir.In this study, an influence to carrying capacity ofDuriangkang Reservoir is conducted toward sedimentation rate atDuriangkang Reservoir by measuring the water column depth ofDuriangkang Reservoir.

Abstract

Mangrove area in Muara Angke was dominated by api-api (Avicenniamarina) and bakau (Rhizophora mucronata). We asume that thesespecies was able to acumulate h eavy metals, since both of them haveadapted in this environmental condition which content of highconcentration h eavy metals. The objective of this experiment was toanalyze heavy metals content in the tissue of api-api (Avicennia marina)and bakau (Rhizophora mucronata) in Muara Angke Jakarta. The resultsshowed that Cu was highest heavy metal content in root of bakau(24.431 ppm) . While 23.674 ppm of Cu was content in api-api roots. Cucontent in sediment was 26,640 ppm.

Abstract

PT. Medco Ethanol Lampung has been constructed factory for cassavaand mollase processing in order to product Rectified-Ethanol at Talang JaliVillage, Kotabumi North Lampung. The estimation of capacity productionis around 190.000 liter per day. Maximum necessity of fresh water forfactory operasional is about 8.507 m /hari. For the measurement depthand water volume Tirta Shinta Reservoir get the volume is about3.155.434 m with the avarage depth for 1 – 6 meter, while the dischargeof water at outflow for agricultural is about 138.270 m per day at rainyseason. If the water from Tirta Shinta reservoir use for main factory, andthe total capacity reservoir only used 4.3 %, if nothing flow from riverbecause dry season, and now Tirta Shinta reservoir can be supply only17.7 month during dry season. Based on the environmental aspect, ifbetter, a fresh water supply for ethanol factory from river has a big rate offlow. This present, beside for farming activity and tourism, the most ofsurface water reservoir covered by water plant that make problem forfactory operational, specially for water pump.
