Abstract

Porong estuary is a place where materials transported along the river have been accumulated as well as Sidoarjo sludge. The amount of sediment in the estuary causes high turbidity levels of the river. The objective of this study is to determine the pattern and the concentration of Total Suspended Solid (TSS) spreading in Porong estuary for 15 days with SED2D models from software SMS 8.1 using maximum and minimum riverflow input, thus, the model results that are closer to reality in nature can be obtained. Tides, currents, and TSS were used as primary data sources, while Porong riverflow, Juanda wind and bathymetry maps Java-North Coast Surabaya to Bali Strait scale 1: 200.000 Sheet V No.82 year 2006 as secondary data sources. The results of the research showed that the concentration of TSS spreading for maximum riverflow 248–158 mg/l and minimum riverflow input 248–160 mg/l with spreading pattern tend to go to southeast direction. TSS concentration spreading model verification indicates that the model with the maximum riverflow data input has smaller MRE value than the model with the minimum riverflow.

Abstract

ENGLISHThe first fisheries management goal is to improve small fishermen’s quality of life. The small fishermen’s quality of life depends on the amount of income earned from the fishing activities. The purposes of this research are (1) to analyze the factors that influence the production of the fishermen in Pecangaan Village, (2) to calculate the return to scale of fishermen in Pecangaan Village. This research used descriptive quantitative method and was conducted on August 2016. The research location is in Pecangaan Village, Batangan Subdistrict. It mainly used primary data derived from the respondent (the fisherman in Pecangaan village). Secondary data were derived from the government of Pecangaan Village, Batangan Subdistrict. The number of processed data was 50 samples. The data analysis used Cobb-Douglas production function, in which dependent variable was production quantities and independent variable were: the amount of solar; the number of days at sea; the number of hours at sea; the sailing distance;fishermen’s consumption during the sailing, GT boats, number of crew and net’s width. The results of the research are (1) the significant factors are the number of days at sea; fishermen’s consumption during the sailing, GT boats and net’s width. Meanwhile, the insignificant factors are the amount of solar; the number of crew, the sailing distance and the number of hours at sea. (2) The value of return to scale in the production offisherman in Pecangaan Villageis -8.699, means it is in the condition of decreasing return to scale. INDONESIATujuan pengelolaan perikanan yang pertama yaitu untuk meningkatkan taraf hidup nelayan kecil.

Abstract

ABSTRAKPenelitian ini berlokasi di Muara sungai Suwatu sampai pantai Bulumanis Kidul dengan pengambilan sampel air dilakukan pada tanggal 4 April 2012 (musim penghujan). Latar belakang yang mendasari penelitian ini adalah karena terdapat muara Sungai Suwatu di pantai Bulumanis Kidul sehingga menjadi wilayah yang rentan terhadap pencemaran. Di muara sungai akan terakumulasi semua bahan buangan yang berasal dari sepanjang aliran sungai Suwatu dan dari laut yang terbawa oleh pergerakan arus. Penyebaran bahan buangan ke laut akan terdorong ke pantai akibat gerakan arus atau gerakan pasang surut, sehingga pantai sekitar juga akan terkena dampak pencemaran yang terjadi di sungai. Kondisi status mutu air Sungai Suwatu yang tercemar berat akan mempengaruhi kondisi pantai Bulumanis Kidul. Tujuan penelitian ini adalah mengkategorikan status mutu air laut di pantai Bulumanis Kidul dengan perhitungan indeks pencemaran. Data yang diperlukan yaitu data konsentrasi parameter fisika (TSS) dan kimia (pH, BOD, DO dan CN). Metode yang digunakan adalah deskriptif kuantitatif dengan teknik pengambilan sampel air menggunakan metode sampling purposif. Pengambilan sampel air dilakukan di empat stasiun yaitu ST1, ST2, ST3 dan ST4. Hasil Penelitian menunjukkan status mutu air di pantai Bulumanis Kidul dengan menggunakan perhitungan indeks pencemaran (IP) berdasarkanbakumutu TSS untuk mangrove yaitu dalam kondisi tercemar sedang dengan nilai indeks pencemaran (IP) antara 5,67-8,22. ABSTRACTThis research is located in the Suwatu estuary to South Bulumanis coast with water sampling conducted on 4 April 2012 (rainy season). The research background based on the existence of Suwatu estuary in South Bulumanis coast that making the area vulnerable to contamination. In the estuary will accumulate all waste material derived from along the Suwatu river and from the sea carried by the movement of currents. The spread of waste material into the sea will be pushed to the shore due to the movement of currents or tidal movements, so the surrounding coastal areas will also be affected by pollution that occurred in the river. Water quality status of Suwatu river that heavily polluted will affect the South Bulumanis coast. The objective of the research is to categorize the water quality status in the South Bulumanis coast using Pollution Index calculations. The required data are concentration of physical parameter (TSS) and chemical parameters (pH, BOD, DO, and CN). The research uses descriptive kuantitative method which the water sampling techniques using purposive sampling method. Water sampling is conducted at four stations ST1, ST2, ST3 and ST4. The result of the research shows that the water quality status of South Bulumanis coast using Pollution Index calculation based on quality standard TSS for mangrove is in condition of moderately polluted IP values between 5.67 to 8.22.
