TSM (Total Suspended Matter) adalah material tersuspensi berupa zat organik maupun anorganik yang memiliki diameter >1mm yang berada di permukaan air, sedangkan Klorofil-A adalah kelompok pigmen fotosintesis yang menyerap cahaya biru, dan merah, serta merefleksikan cahaya hijau. Keduanya dengan jumlah yang besar dapat menutupi permukaan air dan membuat air menjadi hangat dan mengurangi kemampuan air untuk memenuhi kebutuhan oksigen untuk kehidupan biota laut dengan kata lain dapat menganggu ekosistem perairan. Dalam pengamatan kualitas air, perlu adanya pengamatan tentang TSM dan Klorofil-A untuk waktu dan tempat yang spesifik, serta berkelanjutan. Data pengideraan jauh dapat menganalisa beberapa parameter dalam cara spasial dan temporal. Akan tetapi masalahnya adalah sulit untuk menemukan algoritma yang sesuai untuk setiap daerah. Dikarenakan setiap daerah memiliki karakteristik yang belum tentu sama. Dengan menggunakan data time series akan lebih baik dalam memonitoring kondisi kualitas air. MODIS adalah satelit yang memiliki time series harian, jadi sangat bagus untuk pengamatan daerah perairan. Data yang digunakan dalam pengamatan ini adalah Terra-MODIS level 1B resolusi 250 meter dan 500 meter bulan januari sampai september dan di validasi dengan data in situ bulan Agustus 2012. Beberapa model persamaan digunakan dalam penelitian ini untuk menganalisis sebaran konsentrasi TSM dan Klorofil-A. Hasil pengolahan data didapatkan transformasi kromatisiti kanal merah pada MODIS dapat digunakan untuk analisa sebaran koefisien TSM dengan nilai koefisien korelasi (R2) sebesar 0,484 sedangkan rasio antara kanal NIR dengan Kanal biru dapat digunakan untuk analisa sebaran konsentrasi Klorofil-A dengan koefisien korelasi sebesar (R2) 0,924.

The spatial and temporal capabilities of remote sensing data are very effective for monitoring the value of total suspended solids(TSS) in water using optical sensors. In this study,TSS observations were conductedin the westseason, transition season 1, east season, and transition season 2 in 2018 and 2019. Landsat 8 image data wereused,extracted into TSS values using a semi-analytic model developed in the Mahakam Delta, East Kalimantan, Indonesia. The TSS data obtained were then analysed for distribution patterns in each season. The sample points were randomly scattered throughout the study area. The TSS distribution pattern in the west season showeda high concentration spread over the coastal area to theoff sea, while the pattern in the east season only showeda high concentration inthecoastal areas. Transitional seasons1 and 2 showed different patterns of TSS distribution in 2018 and 2019, with more varied values. The distribution of TSS is strongly influenced by the season. Observation of each cluster resultedin the conclusion thathuman activity and the rainfall rate can affect the concentration of TSS.

Sediment is a collection of particles that come from weathering both soil and rock, biological and an anthropogenic process. Sediment flows from upstream to downstream areas. Topographic conditions are one of teh factors in sedimen distribution. The topography in the Wonorejo area tends to be low because it is located in a coastal area. The purpose of this study is to determine the effects of topographic changes in Wonorejo on the distribution of sediments in the area. The method used in this study is descriptive method by collecting data including primary data and secondary data. The primary data used are Landsat 7 and Landsat 8 satellite imagery, while the secondary data used is in the form of Surabaya village administration map data, Surabaya DEM data and Indonesian SHP data. Data processing was performed using ArcGIS 10.3 software. The results indicated that the topographic conditions of the region did not have a significant influence on the distribution of sediments in the Wonorejo area. The distribution of sediment in those area was more influenced by hydro-oceanographic factors such as currents, tides and waves. Other factors that influence are anthropogenic factors such as development and land conversion.

Ekosistem mangrove adalah salah satu obyek yang bisa diidentifikasi dengan menggunakan teknologi penginderaan jauh. Letak geografis ekosistem mangrove yang berada pada daerah peralihan darat dan laut memberikan efek perekaman yang khas jika dibandingkan obyek vegetasi darat lainnya. Efek perekaman tersebut sangat erat kaitannya dengan karakteristik spektral ekosistem mangrove, hingga dalam identifikasi memerlukan suatu transformasi tersendiri. Pada umumnya untuk deteksi vegetasi digunakan transformasi indeks vegetasi. Penelitian ini bertujuan untuk memetakan sebaran dan luasan vegetasi hutan mangrove; dan menentukan tingkat kerapatan atau kesehatan vegetasi mangrove menggunakan indeks vegetasi NDVI dan EVI dari citra Landsat dan SPOT di daerah Segara Anakan, Cilacap, Jawa Tengah. Ekosistem mangrove sebagai salah satu ekosistem penting di kawasan pesisir pantai terus mengalami tekanan di seluruh dunia.Lokasi penelitian Tugas Akhir ini berada di Segara Anakan yang terletak di Kabupaten Cilacap, Propinsi Jawa Tengah, tepatnya pada 7 30’ - 7 44’ LS dan 109 03’ – 109 42’ BT. Indeks vegetasi merupakan suatu algoritma yang diterapkan terhadap citra satelit, untuk menonjolkan aspek kerapatan vegetasi ataupun aspek lain yang berkaitan dengan kerapatan. Metode analisa indeks vegetasi yang digunakan pada penelitian kali adalah NDVI (Normalized Difference Vegetation Index) dan EVI (Enhanced Vegetation Index).Luas tutupan lahan yang didapatkan dari citra Landsat 5 TM tahun 2000 sebesar 50,214.87 ha dan citra SPOT-4 tahun 2008 sebesar 29,774.16 ha. Sedangkan luasan mangrove yang pada tahun 2001 sebesar 5722.74 ha sedangkan pada tahun 2008 sebesar 5453.32 ha. Sehingga bisa disimpulkan terjadi pengurangan luasan mangrove sebesar 269.42 ha.

Clove and soybean are plantations that have high enough economic pontetial. Both of these commodities need suitable land climate condition to grow in optimum. The process of Remote Sensing and climate data with Geographic Information System can determine a suitable land for clove and soybean plantations. Land potential evaluation uses Land Use data that is extracted from Landsat-TM data. The land suitability level is then determined based on climate parameter (rainfall and draught period) and land physical properties for sorbean and clove in Banyuwangi Regency.

The application of Remote Sensing and Geographic Information System are used to evaluate land potential that is suitable for cultivation of fishpond. The parameter that is used in this research is the existing land use by remote sensing and analysis process, topographic/land slope,kind of land, climate data (such as; rainfall and amount of dry season). The evaluation of land potential gives 4 land suitability levels, they are 1)Suitable level:2)Rather suitable level:3)Less suitable level and:4)Non suitable level. The analysis shows that are three areas in Banyuwangi sub-province that is suitable for fishpond cultivation: they are Muncar, Rogojampi, and Pesanggrahan districts.

Segara Anakan and its surrounding which is located in Cilacap Regency Central of Java, is the study area for this research. This region, like other estuaries, has a unique ecosystem which is protected and surrounded by the mangrove forest that can cause very dynamic development. In the upland, there are three big rivers flow; Citanduy, Cibeureum, and Cimeng. The main issue in this region is that the lagoon to become narrowing because of rapid sedimentation process. Landsat MSS, TM, and ETM of the years 1978, 1995, 1998, and 2003 are remote sensing data used in this research. An analysis in term of correlation between landuse/landcover changes and sedimentation was carried out by looking at their changes in the upper land especially along the rivers that have big contribution to the sedimentation in the lagoon. The result shows that there is high relation between landuse/landcover changes in the upper land and sedimentation around the lagoon.

The study of landused change: forest area become coal industrial area and its impact in Total Suspended Solid is done by remote sensing data. The different combination channel of remote sensing data are taken to extract landuse and Total Suspended Solid (TSS) spatial information. The supervised classification is used for land used spatial extraction and otherwise for TSS, there is a specific algorithm; TSS = 3.8926 * exp (31.417*Red Band). The result showed that there was the relationship between landuse change from forest into coal industrial, shrub, paddy field, bareland and settlement area and the dynamic change of TSS along Berau watershed.
