Abstract

ABSTRAK           Produksi ikan yang tinggi dan mutu yang baik adalah sangat diharapkan oleh pelaku perikanan, termasuk di Teluk Jakarta.  Namun hal ini bisa terkendala bila wilayah perairan yang menjadi tempat menangkap ikan (fishing ground) berada dalam status tercemar.  Penelitian ini bertujuan mengidentifikasi status pencemaran fishing ground dan kondisi operasi penangkapan ikan, serta menganalisis dampak pencemaran tersebut terhadap jumlah produksi dan mutu ikan yang tertangkap.  Metode analisis yang digunakan terdiri dari analisis fisiko-kimia, diagram pareto, dan analisis model.Hasil penelitian menunjukkan bahwa perairan di sekitar fishing ground Teluk Jakarta tercemar kuat oleh bau, kekeruhan, sampah, dan logam Hg.  Operasi penangkapan ikan di Teluk Jakarta umumnya menggunakan kapal < 5 GT, berlangsung 1-2 hari/trip, dengan hasiltangkapan dominan berupa ikan tongkol, layang, dan layur.  Pencemaran fishing ground telah secara signifikan menurunkan jumlah produksi ikan di Teluk Jakarta (KP = -0,42, P = 0,00). Penurunan nyata terjadi pada produksi ikan layur (kelompok ikan demersal) dan ikan layang (kelompok ikan pelagis kecil).  Mutu ikan yang tertangkap juga turun secara signifikan akibat pencemaran fishing ground (KP = -0,81, P = 0,00).  Cacat mutu yang secara nyata meresahkan pelaku perikanan adalah insang kotor dan sisik berlendir. Kata kunci : mutu, fishing ground, Hg, pencemaran, ikan  ABSTRACT THE IMPACT OF CONTAMINATION OF FISHING GROUND TO PRODUCTION AND QUALITY OF FISH CAUGHT IN JAKARTA BAY. High production and quality of fish are very expected by fishery stakeholders, inclusive in Bay Jakarta.  But this matter can be burdened if territorial water with becoming fishing ground have contaminated status. The research aims to identify the contaminated status of fishing ground and operating conditions of fishing, and also to analyse the impact of its contamination to production and quality of fish caught. This research methods are physics and chemical analysis, diagram pareto, and model analysis. Research result shows that fishing ground in Bay Jakarta have been contaminated by aroma, turbidity, garbage, and Hg metal. Fishing operations in the Jakarta bay generally boat <5 GT, lasts 1-2 days / trip, with dominant catches form of tuna fish, float fish, and sword fish. The contamination of fishing ground have degraded significantlythe production amount of fish in Jakarta Bay (KP = -0,42, P = 0,00). The real degradationsare in production of sword fish (group of demersal fish) and float fish (group of small pelagic fish). The quality of fish caught also have droped significantly as impact by the contamination of fishing ground (KP = -9,81, P = 0,00).  Quality defect freting clearly to fishery stakeholders are dirty gills and muccous of fish scales. Keywords :quality, fishing ground, Hg, contamination, fish

Abstract

Mangrove ecosystem is a region that acts as a transition between land and sea. This ecosystem has ecological, socio-economic and physical functions. The decline in the quality and quantity of mangrove forests has resulted in very alarming impacts, such as increased abrasion, reduced fishing catches, seawater intrusion, and others. This study aims to analyze the biodiversity of mangrove ecosystem in the Randutatah coal. The results showed that mangrove ecosystems were dominated by Rhizophora stylosa species with the highest INP values in tillers and tree categories. Observations of fauna in the area found 2 types of mammals, 34 species of birds, 7 species of herpetofauna, and 9 species of insects. the wealth of bird species in this region is high. Phytoplankton composition is dominated by Bacillariophyceae class, zooplankton is dominated by crustacean class, and nekton is dominated by Mugilidae class. Mangrove conditions in Randutatah can increase biodiversity in these locations, as well as the condition of the waters around the mangrove ecosystem that become fertile so that it can be used by the community to catch fish or crabs that have an impact on the growth of the economic value of the community.

Abstract

The territorial waters of Jayapura City, especially the waters of North Jayapura and South Jayapura are the centers of capture fisheries activities of big pelagic species, namely tuna and skipjack tuna, which need to be utilized to provide welfare for the community, especially fishermen in a sustainable manner. For this reason, this study was conducted to analyze the level of utilization of big pelagic fisheries resources and analyze the welfare level of big pelagic fishermen households in Jayapura city waters. Primary data collection is done through interviews with respondents who are randomly selected. Utilization level analysis was carried out using multispecies bioeconomic analysis and analysis of fisherman welfare levels was carried out using the criteria of the poverty line set by the Central Bureau of Statistics. The results showed the actual utilization rates of tuna and skipjack fisheries resources in the waters of Jayapura City are still in the continuous production of MSY and MEY. Nevertheless, the utilization of these big pelagic fisheries resources needs to be supported by economic institutions that can better distribute their benefits, especially to fishermen. This is because based on the survey conducted; most of the household welfare of the big pelagic fishermen tuna and cakalang in the waters of Jayapura City are still classified as not prosperous.

Abstract

Peat nutrient dynamics research was intended to study the characteristics and distribution of macro nutrients in peat water and peat in secondary forests, shrubs and oil palm plantations. This research was conducted with purposive sampling method. Observations on oil palm plantations were carried out at three ages of oil palm (5, 12, and 16 years). Secondary forest and shrub peatlands were used as a comparison. Sampling of peat water and peat was carried out during the rainy and dry season, at four distances from the collection drain (25, 50, 75, and 150 m). The results showed that nutrient levels in peat water during the dry season were greater than the wet season. The status of peat water and peat nutrients in secondary forests and shrubs is relatively the same as that of oil palm plantations that were fertilized. Seasonal, land use and distance from the collection channel differences did not have a major influence on the distribution and characteristics of macro nutrients on peat. The macro nutrients content of peat water and peat, however, showed an increase with the distance from the collection channel.

Abstract

Community forest management are individualized according the decision of the land owners and yet have a standardized manage-ment method. Characteristics of community forest have a high diversity at the level of the land owners. Community forest sustainability can be seen from the forest stand structure. The aim of this study was to obtain horizontal stand structure model and compile yield regulation method for each community forest land ownership. Information of the community forest stand in the Cidokom Vil-lage, Rumpin District obtained exploratively and preparation of the yield regulation method analyzed descriptively.  Sample of sub-districts, villages, and community forest owners was determined by purposive sampling by considering the potential of community forests, technical convenience in the field, accessibility of research locations, and representation of land area data in community forest land ownership groups. From negative exponential function at community forest, obtained ?k? values ranges between 39.71?2318.99 and ?a? values ranges between -1.58?0.01. The results showed that the stand structure of each land owners of community forest varies and yield regulation method can be used by the community forest landowners which can be adjusted with the cutting decision and land contition to achieve community forest sustainability.

Abstract

The existence of Aesesa Flores (AF) watershed is very important for people in Ngada and Nagekeo Regency of Flores island. The AF watershed provides water, land use, economic and other environmental services. However, the excessive exploitation is a major threat for the existence of the AF watershed. The degradation of the AF watershed function such as reduction in river debit, increase of critical land, land use change as well as the problem of poverty. The upstream area is intended as a conservation area where Watu Ata nature preservation park is located, the bamboo forest and Bajawa as the capital city of Ngada Regency. The downstream area is not only as capital city of Nageko Regency but also as paddy field area. One of the activity to improve the watershed function is through a comprehensive and sustainable management policy design based on characteristics and carrying capacity of the AF watershed. This research was conducted in April-May 2018 and the the purpose of the study is to analyzed key factors and establishing an alternative for sustainable management policy development of AF watershed using a prospective method. This study using mainly primary data obtained from the seven local experts through the filling of the questionnaire. The result shows that there are 22 attribute factors and it identified as 10 key factors. The main two key factors are bamboo cultivation, processing technology of bamboo, enlargement of bamboo cultivation area and practicing the soil and water conservation technique. The 10 key factors then become input for designing the management policy of AF watershed. Bamboo become the dominant and key factor because bamboo could be developed into biomass energy plant and it serves social, economic and ecological values for the local people of Ngada and Nagekeo Regency. Bamboo cultivation has a good prospect financially for the local people.

Abstract

Bogor City has been declared a City of Water Sensitivity. For this reason, each housing needs to process domestic wastewater, one of which uses bioretension, before entering the nearest surface water body. The purpose of this study was to determine the quality of domestic wastewater from Griya Katulampa housing, where the drainage channels flow directly into the Ciliwung River and analyze the effectiveness of the use of bioretension to improve the quality of domestic wastewater caused. Bioretence with filter media includes 50% sandy soil, top soil 20-30%, and mulch 20-30% and the vegetation used consists of Kana (Canna sp), Air Jasmine (Echinoderus palifolius), Cyperus (Cyperus papyrus) made. Measuring the quality of domestic wastewater is carried out at the installation inlet and outlet. The result showed that domestic wastewater from Griya Katulampa was still below the specified quality standard. Bioretence with fiber media and cane plants can be used to reduce TSS as a parameter that has a value above the specified quality standard. To increase added value, water spinach can be planted as a hydroponic plant that can grow and has the highest productivity value.

Abstract

Municipal solid waste management is a public service that should be provided by the government and needs a significant portion of the government budget, so it is deemed as a cost center. Often, benefit from the waste management could not directly be nominalized into money. The study aims to compare the total cost needed and benefit taken, directly and indirectly, using Cost Benefit Analysis (CBA) and puts Pekanbaru City as a case study. Recently, there were 5 units of waste recycling facility (TPS 3R), 5 units of composting facility, and 145 unit of waste bank available in Pekanbaru City. In order to compare with the existing condition, the study developed 2 scenarios related to the recycling facilities, namely Scenario A for optimizing capacity of the facilities, and Scenario B for providing 2 facilities in each sub-district until 2025. The result shows that the Benefit Cost Ratio (BCR) value were 2.903 for Scenario A, and 4.478 for Scenario B, comparing to 1.624 for the existing condition. The  study provides a proof that the municpality should prioritze waste treatment rather than waste disposal as it has higher total benefit and the measure is in-line with the national policy on waste management.
