Abstract

Pemilihan lokasi tambak yang salah akan menimbulkan masalah, diantaranya adalah meningkatkan biaya konstruksi, operasional, dan dapat menimbulkan masalah lingkungan. Tujuan penelitian ini adalah untuk mengevaluasi kesesuaian lahan tambak udang dengan mempertimbangkan perencanaan sempadan pantai dan sempadan sungai di Kecamatan Cijulang dan Parigi. Penelitian ini menggunakan Sistem Informasi Geografis (SIG) dalam menentukan tingkat kesesuaian lahan tambak yang ada di lokasi tersebut. Parameter yang diperhitungkan dan dianalisis adalah: penggunaan lahan; tekstur tanah; jenis tanah; kelerengan lahan; jarak dari sungai; jarak dari pantai; pH air; dan salinitas. Hasil analisis spasial tersebut kemudian ditambahkan faktor pembatas sempadan sungai dan pantai sehingga luas tambak udang seluruhnya yang sebesar 23,8 ha terbagi menjadi tiga kelas kesesuaian, yaitu sangat sesuai sebesar 11,7 ha (49,0%); sesuai sebesar 1,0 ha (4,3%); dan tidak sesuai sebesar 11,1 ha (46,6%). Tidak terdapat tambak di area sesuai bersyarat. Tambak yang eksis di wilayah ini hampir seluruhnya berada pada wilayah yang seharusnya menjadi sempadan sungai. Agar tercipta pengelolaan tambak yang lestari, perlu adanya kerjasama yang baik antara pengelola tambak dengan pemerintah.

Abstract

Diffuse attenuation coefficient from downwelling irradiance measurement is one of the important oceanography parameter that provide information on light availability and the light penetration through waters column that represent the waters clarity, photosynthesis and other biological processes. Information about diffuse attenuation coefficient play an important role on the development of bio-optical algorithm on Ocean Color satellite data. The aim of this research is to know the variability of diffuse attenuation coefficient in the shallow water of Karang Lebar, Air and Panggang island using irradiance sensor from hyperspectral radiometer TriOS-RAMSES covering a wavelength range from 320 to 950 nm with 3.3 nm spectral resolution. In situ measurments performed by pull down the irradiance sensor on each depth vertically in waters column up to just before the sea floor. Overall, the measurement result showed that values of Kd(λ) had patterns tends to be decreased on blue-green region wavelength (380-480 nm) and increased again on green-red region (560-760 nm). We found that values of Kd(λ) inside of gobah area had greater values than the outside gobah, significantly the difference significantly occured on all regions that Kd(λ) values measured (F = 5.581 > F critical = 5.554), where each regions has different characteristics to each others. Kd(λ) values dominantly affected by absorbtion of chlorophyll-a with determination cofficient R2 = 0.808 compared with backscattering by suspended solid with determination coefficient R2 = 0.043. Kd(λ) values on visible wavelength regions (400-700 nm) can describe information about how far light can be detected by Ocean Color satellite from water column represented by one optical depth. Relationship of Kd(λ) values with one optical depth can be describe as exponential equation Kd(400-700 nm) = 0.6747*exp(-0.231*1ζ) with the determination coefficient R2 = 0.97.

Abstract

Koefisien atenuasi merupakan gambaran seberapa besar cahaya datang berkurang atau hilang dibandingkan dengan energi cahaya datang di permukaan. Pengurangan energi cahaya dikarenakan adanya proses absorpsi dan hamburan oleh kolom air dan materi yang terkandung di dalamnya seperti fitoplankton, padatan tersuspensi dan colored dissolved organic matter. Kuantitas cahaya yang mengalami atenuasi setara dengan jumlah cahaya yang diabsorpsi dan dihamburkan. Penelitian ini bertujuan untuk menganalisis hubungan antara koefisien atenuasi dengan kualitas air, serta mengkaji karakteristik optik perairan Kelurahan Pulau Panggang. Pengukuran spektral menggunakan TriOSRamses yang memiliki sensor irradiance dengan panjang gelombang antara 320 nm sampai 950 nm dan rentang kanal 3,3 nm. Perhitungan koefisien atenuasi (Kd) berdasarkan perubahan downwelling irradiance pada dua kedalaman berbeda. Korelasi Pearson digunakan untuk mengetahui hubungan antara Kd dengan kualitas air. Berdasarkan rentang panjang gelombang, Kd dibagi menjadi 4 yaitu Kd PAR, Kd biru, Kd hijau dan Kd merah. Kd biru dan Kd hijau memiliki hubungan paling erat dengan kecerahan sebesar 0,5406 dan 0,3990 serta bersifat negatif, sedangkan Kd PAR dan Kd merah paling erat hubungannya dengan muatan padatan tersuspensi sebesar 0,4015 dan 0,4073 dan bersifat positif. Perairan Kelurahan Pulau Panggang merupakan perairan turbid dengan nilai Kd PAR > 0,115 m-1.

Abstract

The blue swimming crab in the waters of Lancang Island is indicated as being overfished. Hence, the major challenge is managing its utilization in a proper manner. The purpose of this study is to explore the water's characteristics which is suitable for blue swimming crab fishing. Accordingly, the potential fishing ground around Lancang Island waters can be mapped spatially as an initial effort for species preservation. Geospatial analysis was applied to assess the physical parameters of the existing habitat. The results show that parameters such as MPT, TDS, brightness, phosphate, nitrate, depth and substrate types were remarkably suitable to support the growth of blue swimming crabs. Meanwhile, parameters such as salinity, DO, and temperature show lower quality which implied that the habitat is less suitable. However, the result of weighting and reclassification conclude that Lancang island waters is a decent habitat for blue swimming crab. Catch data show that 40% blue swimming crabs have small carapace size (7-11.83 cm) which is undersized and prohibited by law. Furthermore, about 68% of catch are quite light (30-147 gr) and the sex ratio of males to females was 1:2. It was also revealed that approximately 35% of female species were carrying eggs (BEF/barried female). Keywords: geospatial, fishing ground, suitability, Lancang Island, blue swimming crab.

Abstract

Shallow marine waters comprise diverse benthic types forming habitats for reef fish community, which important for the livelihood of coastal and small island inhabitants. Satellite imagery provide synoptic map of benthic habitat and further utilized to estimate reef fish stock. The objective of this research was to estimate reef fish stock in complex coral reef of Pulau Pari, by utilizing high resolution satellite imagery of the WorldView-2 in combination with field data such as visual census of reef fish. Field survey was conducted between May-August 2013 with 160 sampling points representing four sites (north, south, west, and east). The image was analy-zed and grouped into five classes of benthic habitats i.e., live coral (LC), dead coral (DC), sand (Sa), seagrass (Sg), and mix (Mx) (combination seagrass+coral and seagrass+sand). The overall accuracy of benthic habitat map was 78%. Field survey revealed that the highest live coral cover (58%) was found at the north site with fish density 3.69 and 1.50 ind/m2at 3 and 10 m depth, respectively. Meanwhile, the lowest live coral cover (18%) was found at the south site with fish density 2.79 and 2.18  ind/m2 at 3 and 10 m depth, respectively. Interpolation on fish density data in each habitat class resulted in standing stock reef fish estimation:  LC (5,340,698 ind), DC (56,254,356 ind), Sa (13,370,154 ind), Sg (1,776,195 ind) and Mx (14,557,680 ind). Keywords: mapping, satellite imagery, benthic habitat, reef fish, stock estimation

Abstract

The study of shoreline changes during 1990 - 2008 in the delta of the River Jeneberang, Makassar was conducted by evaluating sediment transport into and out of a cell. Longshore sediment transport was computed by considering the influence of heights and angles of the breaking waves. Results of calculation of sediment transport showed that the dominant of sediment transport was to the north during the arrival of the southwest and west waves, and to the south when the wave coming from the northwest. Comparison between shore profiles resulting from model and coastline satellite imagery showed similarity. The difference between the two tend to be occurred at the head land part of the shoreline. This was due to complexity of coastal dynamic at the area. The results of the 19 years shoreline simulation showed that there was a tendency of abrasion at the upsteam head land part as the wave energy tend to converge and accretion at the bay part as the wave energy tend to diverge. Abrasion mainly occurred at Tanjung Bunga (head land) where the coast retreat 181.1 m. Accretion occur in the bay area (Tanjung Merdeka) where the coast advance to the sea for about 59.8 m. The shoreline tend to be stable when the profile was straight such as Barombong Coast.Keywords: abrasion, accretion, sediment transport, shoreline changes.

Abstract

Suatu model batimetri digital dapat dibangun melalui interpolasi sejumlah besar titik kedalaman hasil pemeruman. Studi ini menggunakan dua skenario pengolahan yaitu menggunakan keseluruhan data perum dan menggunakan data perum terpilih. Pada setiap skenario pengolahan data, ada tiga metode interpolasi yang dibandingkan yaitu metode inverse distance to power, kriging dan minimum curvature.Nilai RMSE yang didapatkan dari masing-masing interpolator pada setiap skenario tersebut ternyata cukup bervariasi. Secara umum metode Kriging lebih efektif digunakan untuk menghasilkan gambar kontur kedalaman perairan dibandingkan dengan metode lainnya. Hasil studi ini memperlihatkan perlunya penanganan data agar pola suatu unsur spasial (kontur kedalaman) dapat ditampilkan secara lebih baik.Kata Kunci: interpolasi, kriging, inverse distance to power, minimum curvature,batimetri
