Abstract

Kelangkaan data spasial kelautan merupakan permasalahan mendasar dalam perencanaan pembangunan kelautan di negara berkembang seperti lndonesia. Untuk mengatasi permasalahan ini, teknologi inderaja menjadi salah-satu alternatif pilihan. Salah satu ekosistem laut yang mengandung kekayaan sumberdaya alam adalah ekosistem terumbu karang. Pemanfaatan data inderaja untuk pemetaan ekosistem terumbu karang telah diperkenalkan di lndonesia sejak tahun 90-an dan saat ini sudah umum digunakan di Indonesia. Namun demikian, data inderaja mempunyai keterbatasan untuk memetakan objek terumbu karang karena berada hingga kedalaman tertentu yang tidak ada penetrasi cahaya. Pola distribusi terumbu karang yang mengikuti geomorfologi dasar perairan sangat mempengaruhi hasil penginderaan. Hasil penelitian di kepulauan Una-una Togean menuniukkan bahwa interpretasi dari citra satelit tidak menggambarkan kondisi terumbu karang yang sesungguhnya.Kata Kunci: Data Spasial, Kelautan, Inderaja, Terumbu Karang ABSTRACTThe lack of marine spatial data is the fundamental problems in marine development planning in developing countries like Indonesia. We need remote sensing technology to be one alternative option to get over this problem. A coral reef ecosystem is one of the marine ecosystems that contain a rich of marine resources. Utilization of remote sensing data for napping coral reef ecosystems have been introduced in Indonesia since the 90’s and now is commonly used in Indonesia. However, the remote sensing data has limitations for coral reef napping object being in a certain depth into which has no light penetration. Distribution patterns of coral reef following the bottom geomorphology of water influence the sensory results. The results of research conducted in the Una-una Togean Island showed that the coral reef map derived satellite images did not describe the real condition of the reef.

Abstract

ABSTRAKSalah satu hal yang menarik untuk dikaji mengenai perairan Indonesia adalah dengan adanya istilah yangmendunia yaitu Indonesian Through Flow atau yang dikenal dengan istilah Arus Lintas Indonesia (ARLINDO). Melaluipemahaman tentang oseanografi terutama oseanografi fisika maka dapat dipelajari kondisi fisik suatu wilayah perairanbeserta karakteristik dari perairan tersebut. Saat ini parameter oseanografi fisika dapat dideteksi denganmenggunakan teknologi penginderaan jauh. Penelitian ini bertujuan untuk memantau dinamika massa air permukaandi Perairan Selat Makassar dengan menggunakan potensi dan pemanfaatan teknologi penginderaan jauh. Data yangdigunakan dalam penelitian ini adalah data citra satelit Terra dan Aqua MODIS level 1 dengan resolusi 1 km dalamformat Hierarchical Data Format (HDF). Data sebaran Suhu Permukaan Laut (SPL) adalah data harian selama duatahun (2009-2010) dengan citra SPL untuk mendapatkan data time series. Data pendukung yang diambilmenggunakan teknologi penginderaan jauh adalah curah hujan, kecepatan dan arah angin yang merupakan datasekunder. Setiap bulan ada 2 sampai 3 data harian yang layak untuk diolah, hal yang menjadi kendala paling besaradalah banyaknya citra yang tertutup awan sehingga data yang didapat tidak dapat menggambarkan kondisi PerairanSelat Makassar. Dinamika massa air permukaan yang menunjukkan pergerakan massa air permukaan terlihat melaluipola SPL yang terbentuk di Selat Makassar. Massa air permukaan bergerak dari utara ke selatan perairan terdeteksidi Bulan Maret 2010 dan dari selatan ke utara di Bulan Juni 2010.Kata Kunci: Massa Air Permukaan, Selat Makassar, MODIS, Suhu Permukaan Laut.ABSTRACTStudy on Indonesia Through Flow of Makassar Strait is very interesting subjects considering that this term isbocome globally welknown. By understanding its physical oceanography, the characteristic of this waters can belearned. Current technology developments enable scientist to study, physical oceanographic parameters by usingremote sensing technology. This study aims to monitor the dynamics of the surface water mass in Makassar Straitusing the advancement of remote sensing technology. The data used in this study is satellite image data of Terra andAqua Moderate Resolution Imaging Spectroradiometer (MODIS) level 1 with spatial resolution of 1 km stored inHierarchical Data Format (HDF) format. Meanwhile, daily Sea Surface Temperature (SST) data of two consecutiveyears (2009-2010) were used to obtain time series data of the SST. The other supporting data were rainfall data andwind direction and speed. The biggest obstacle found in this study is that many areas were covered by cloud so thatthe images data could not be used to describe the Makassar Strait waters condition. The result of this study thatdynamics of surface water mass that show the movement of surface water mass distribution can be seen from thepatterns of SST in Makassar Strait. Surface water mass at the Makassar Strait moves from north to south in March2010 and was appeared in opposite flow in June 2010.Keywords: Surface Water Masses, Makassar Strait, MODIS, Sea Surface Temperature.

Abstract

Accurate and up-to-date information of marine resources is needed for optimum resource utilization. If the required information cannot be obtained with traditional field surveys, remote sensing as a tool for providing fast, efficient, and accurate information is used to detect the changes. The study aims to use remote sensing data for assessing distribustion and condition of marine resources in Nias water's before and after tsunami. Marine resources pararameter derived remote sensing data are sea surface temperature (SST), suspended solid matter, chlorphyll-a concentration, coral reef and mangrove distributions. Mapping and differences in coral reef and mangrove distribution were evaluated using two scans of Landsat image in 1989 and 2005. Sea surface temperature was derived from NOAA-AVHRR data, and chlorophyll-a concentration was derived from SeaWiFS data. The study showed that there were no significant changes of coral reef and mangrove distribution, SST, chlorophyll-a concentration after and before tsunami. Spectral analysis of SST and chlorophyll-a showed that the variability of the parameters was affected by monsoon system and global climate change, namely El Nino Southern Oscillation and Indian Ocean Dipole.Keywords: remote sensing, satellite, Nias, tsunami, chorophyll-a, coral reef, mangrove

Abstract

Pemetaan lahan yang potensial untuk budidaya perikanan dilakukan melalui pemetaan topografi dan tutupan lahan dari citra satelit serta survei lapang di perairan pantai Timur Belitung.  Peta Topografi estimasi dari citra satelit mempunyai pola yang sama dengan hasil pengukuran terestris dimana ketinggian lahan semakin meningkat mulai dari garis pantai menuju daratan. Data hasil pengukuran topografi secara terestris lebih tinggi dari data topografi estimasi dari data satelit. Tipe pasut di perairan pantai Belitung timur adalah tipe tunggal. Data pasut ini digunakan menjadi acuan untuk pengukuran topografi secara terestris. Peta tutupan lahan hasil intrepretasi dari citra satelit diklasifikasikan menjadi kelas: hutan primer, hutan sekunder, belukar, rawa/air, lahan terbuka, permukiman dan galian tambang. Berdasarkan peta topografi, peta tutupan lahan dan data pasang surut maka lahan di wilayah kajian pesisir pantai Timur Belitung potensial dikembangkan untuk budidaya perikanan seluas 9.000 ha. ABSTRACT Mapping potential land for aquaculture was done through topography, and land cover mapping derived satellite imagery and field survey in the east coast of Belitung. Topographic data derived satellite, and terrestrial measurement shows that topographic patterns increase as we move from the coastal line to inland. Topographic data from the terrestrial measurement was higher than satellite estimations. The type of tide in the east coast Belitung’s is the diurnal type. Within this research, tidal data was used as a reference terrestrial topographic measurement.   Land coverage maps from satellite images were classified into primary and secondary forests, grove forests, marsh/water lands, open land, inhabited land, and mining areas. According to topographic, land cover map, and tide pattern it can be confirmed that the eastern coastal area of Belitung has the potential to be developed into an aquaculture fishery area of 9,000 ha.

Abstract

Variability of chlorophyll-a concentrations of the northern Sumbawa waters was investigated based on SeaWiFS satellite data for the period of January 1998-December 2007. Chlorophyll-aconcentration was estimated employing OC4v4 algorithm. Chlorophyll-a concentrations of,SeaWiFS satellite data were obtained from the Goddard Space Flight Center, NASA archieve data. In general, fluctuations of chlorophyll-a concentration of the northern Sumbawa waters had three patterns i.e., the maximum with a range of 0,21-0,74 mg/m3 occurred during the West Season (November-February), the minimum with a range of 0.12-0.15 mg/m3 occurred during Transition Season I (March-April), and relatively high (second peak) with a range of 0.21-0.36 mg/m3 occurred during the mid-East Season until the beginning of Transition Season II (July-September).High chlorophyll-a concentration occurred during the West Season was closely related to the high rainfall, the possibility of vertical water mass mixing,and upwelling process in the northern coastal waters of Sumbawa. Meanwhile, the relatively high (second peak) of chlorophyll-aconcentration occurred in July-September was caused by the movement of water masses from the South of Makassar Strait containing relatively high chlorophyll-a concentrations and relatively low temperatures since upwelling processes occurred at this location in the same period.

Abstract

Hutan mangrove merupakan ekosistem yang rentan sehingga membutuhkan pemantauan terus menerus untuk mendeteksi berbagai ancaman seperti aktivitas manusia dan bencana alam. Penginderaan jarak jauh dan sistem informasi geografis (SIG) sangat efektif untuk digunakan dalam pemantauan ekosistem mangrove karena dapat menjangkau daerah yang luas dan dapat dilakukan sekala berkala. Penerapan teknologi penginderaan jarak jauh untuk memantau ekosistem mangrove di Pulau Sebatik belum pernah dilakukan sebelumnya. Penelitian ini penting untuk mengetahui perubahan kondisi hutan mangrove di Pulau Sebatik. Tujuan dari penelitian ini adalah untuk menghitung akurasi klasifikasi tutupan lahan dengan resolusi spasial yang berbeda, mengukur perubahan mangrove dari tahun 2005 sampai 2016, dan menganalisis korelasi antara nilai Normalized Different Vegetation Index (NDVI) dan persentase tutupannya. Klasifikasi tutupan lahan dalam penelitian ini menggunakan klasifikasi terbimbing dengan algoritma Maximum Likelihood. NDVI digunakan sebagai indikator kerapatan mangrove. Pengukuran data lapangan diambil untuk menghitung tutupan kanopi. Penilaian akurasi klasifikasi citra Landsat sekitar 83% dan citra SPOT 6 sekitar 90%. Mangrove di Pulau Sebatik mengalami peningkatan dari tahun 2005 sampai 2016 sebesar 31,27%. Korelasi antara tutupan NDVI dan kanopi dikategorikan tinggi dengan koefisien korelasi r = 0,82 (Landsat 8) dan 0,85 (SPOT 6).
