Pola Pencemaran Lokasi Penangkapan dan Ikan Hasil Tangkapan Akibat Berkembangnya Aktivitas Ekonomi di Sekitar Danau Maninjau

Maninjau Lake is the territorial waters of which contribute greatly to fish production in Agam, West Sumatra. But a lot of waste of economic activities discharged into the lake. This study aims to analyze the characteristics of fishing, contamination status of fishing ground and fish caught, to analyze the contamination pattern of fishing ground and fish caught as effect of economic activity waste. The methods used are descriptive method, physic-chemical analysis, correlation method, and multiple regression method. The results showed the fishing in Lake Maninjau, generally using langli net, lift net, hook and lines, and cast net. While the main fish caught are nile tilapia, bada fish, rinuak fish, carp, and limbek fish. Fishing ground in Maninjau Lake contaminated by ammonia, garbage, Cd and Hg metals, while the fish caught, there was found to have gills dirty. Significantly, fishing ground disturbed by the waste of hydropower (X1), lake tourism (X2), settlements (X4), and KJA fisheries (X5). The contamination pattern of fishing ground formulated by Y1=0,220X1+0,085X2+0,227X4+0,204X5-4,540. Fish production disturbed significantly by the waste from hotel and restaurants (X3), seattlements (X4), and KJA fisheries (X5). The contamination pattern of fish caught, represented by a decrease in fish production (Y2) formulated by Y2 =1,195X3+2,152X4+5,140X5-41,664.

FAKTOR-FAKTOR YANG MEMPENGARUHI KINERJA PEMBANGUNAN PERIKANAN: STUDI KASUS PADA PERIKANAN TANGKAP DI INDRAMAYU (Factors affecting the performance of fisheries development: A case study of capture fisheries in Indramayu)

Various policies of fisheries development have been implemented by Indonesian government. However, they have not reached the expected results. Until now the policy/program of empowerment has not been able to significantly increase fishermen income and welfare. Fishermen are still poor and underdeveloped compared to other community groups. Therefore, some corrective measures are needed to improve programs/policies that have been implemented over the years. To get the answer, a study that examines factors affect the success of a fisheries policy is conducted in Indramayu, West Java. By using analysis of Structural Equation Modelling (SEM), the research defines that fisheries institutions factor significantly led to the success of fisheries development.

EFFICIENCY ANALYSIS OF PURSE SEINE FISHING UNIT COASTAL FISHING PORT LAMPULO BANDA ACEH

The purpose of the study is to analyze the influence level of the production factors to development of the tuna fishing industry in Ambon City. The data collected are the vessel size, gear size, long trip, fuel use, ice use, fresh water and the number of crew. The data comes from Ambon tuna fishermen. Data collected are primary and secondary data. The analysis used is multiple regression analysis. Multiple regression analysis of the relationship of tuna production gets the value of significance (sig) 0,000. Sig be in the range of beliefs <0.005 means that the regression model can predict the tuna fishery production. Determinant coefficient (R2) of about 0.719 shows the influence of production factors together could explain 71.9% up and down the production of tuna. Base on the significance value of each production factor to production, only the use BBM (X4) and the use of ice cubes (X5) which has a significance value <0.05 (0.000). Use of X5 is influential but has no effect supports the development of tuna in Ambon City. Conclusions taken from this study is the production of factors that influence the production of tuna fisheries in Ambon is the use BBM and the use of ice cubes (X5) which has a significance value <0.05 is 0.000.

MONSOON AND SKIPJACK FISHING GROUND IN THE BANDA SEA AND ITS SURROUNDING MOLUCCAS PROVINCE

Suhu permukaan laut (SPL) dan klorofil-a (CHL) merupakan parameter oseanografi yang penting dan sering digunakan untuk memprediksi daerah penangkapan potensial menggunakan remote sensing. Tujuan penelitian ini adalah menganalisis dan memetakan daerah penangkapan ikan cakalang di Laut Banda dan sekitanya Provinsi Maluku berdasarkan perubahan musim. Data SPL dan CHL diambil dari analisis data citra satelit, hasil observasi sensor Aqua MODIS level 3 dengan resolusi spasial 4 km dan resolusi temporal bulan dan musiman. Data citra dianalisis dengan program SEADAS 5.2. Hasil analisis menunjukkan suhu permukaan laut (SPL) dan konsentrasi klorofil-a di Laut Banda dan sekitarnya mengalami fluktuasi dari bulan ke bulan. Kondisi ini mempengaruhi fluktuasi SPL dan CHL musiman. Rata-rata suhu tertinggi berada pada musim barat dan pancaroba pertama sedangkan suhu terendah di musim timur. Berbeda dengan konsentrasi klorofil-a, tertinggi pada musim timur dan terendah pada musim pancaroba pertama. Ada korelasi antara peningkatan suhu dan penurunan konsentrasi klorofil-a. Suhu permukaan laut juga memiliki korelasi negatif dengan CPUE dan mempengaruhi pembentukan daerah penangkapan ikan. Daerah penangkapan cakalang di Laut Banda dengan CPUE tertinggi pada semua musim ada di sebelah barat Pulau Seram sekitar Pulau Buano, Kelang dan Manipa atau pada posisi 126,7o-128o BT dan 2.6o-3.4o LS, di sekitar Laut Banda pada posisi 127o-130,3o BT dan 3.2o-4o LS.

EVALUASI LUASAN KAWASAN MANGROVE UNTUK MENDUKUNG PERIKANAN UDANG DI KABUPATEN CILACAP PROVINSI JAWA TENGAH (Evaluation of the Mangrove Area Extents to Support Fishing Shrimp in Cilacap Regency, Central Java Province)

ABSTRACT Cilacap waters are rich with shrimp resource, particularly from Penaidae spp species, such as shrimp Jerbung (Penaeus merguensis) and shrimp Dogol (Metapenaeus endevouri and Metapenaeus ensis). Statistic data of shrimp in Cilacap showed shrimp production keep on declining, from 1,118,644 kg in 2004 to 818,595 kg in 2008. The declining production is suspected due to the increasing intensity of catching and the damage of ecology in coastal areas, particularly the mangrove. This research is aimed at mapping the mangrove areas, and estimating stock of shrimp resource in Cilacap. Data analysis was conducted by using spatial analysis and analysis of potential resource of fish. Results of the analysis showed that estimated mangrove forest in Cilacap in 2005 was about 14,502.55 ha, reduced to about 9,326.71 ha in 2007 and continue to decline to about 2,618.78 ha in 2009. Estimated score of MSY shrimp is 955,493.34 kg/year, with optimum catch 55,014.68 trips. Keywords: analysis of surplus production, Cilacap, mangrove, shrimp, spatial analysis ------ ABSTRAK Wilayah perairan Kabupaten Cilacap kaya akan sumberdaya udang, khususnya dari jenis Penaidae spp., diantaranya yaitu udang jerbung (Penaeus merguensis) dan udang dogol (Metapenaeus endevouri dan Metapenaeus ensis). Data statistik perikanan udang di Cilacap menunjukkan produksi udang terus mengalami penurunan yaitu dari 1.118.644 kg pada tahun 2004 menjadi 818.595 kg pada tahun 2008. Penurunan produksi udang di Cilacap diduga disebabkan oleh meningkatnya intensitas penangkapan dan kerusakan ekologi kawasan pesisir, khususnya hutan mangrove. Penelitian ini bertujuan untuk menyusun peta untuk menghitung luas kawasan lahan mangrove, dan mengestimasi stok sumberdaya udang di Kabupaten Cilacap. Analisis data dilakukan dengan menggunakan analisis spasial dan analisis potensi sumberdaya ikan. Hasil analisis menyatakan bahwa estimasi luasan kawasan hutan mangrove di Cilacap pada tahun 2005 sekitar 14.502,55 ha, menurun menjadi sekitar
