Abstract

Temperature is one of the important parameter for volcano eruption prediction. Remote Sansing Data can be used to measure land surface temperature. The land surface temperature can be calculated with the band 4 and 5 of NOAA Satellite data by implementing the land surface temperature algorithm (LST). From field observation and measurement of volcano Merapi temperature indicate a significant pattern between the creater temperature and the land surface temperature derived from satellite data which shows increasing near eruption.

Abstract

Kerusakan Daerah Tangkapan Air (DTA) dan penurunan kualitas perairan danau telah banyak terjadi di wilayah Indonesia sehingga Pemerintah Indonesia membuat program pengelolaan dan penyelamatan bersama ekosistem danau prioritas. Kegiatan ini mengkaji pendugaan laju erosi tanah di DTA Danau Kerinci menggunakan data satelit multi temporal Landsat TM/ETM+ dan SPOT-4. Standarisasi data dilakukan untuk menjaga konsistensi nilai Normalized Difference Vegetation Index (NDVI) karena pengaruh perbedaan waktu perekaman, sensor perekaman dan pengaruh tutupan awan. Informasi NDVImin dan NDVImax diekstrak dari 19 data Landsat TM/ETM+ periode 2000-2009, kemiringan lahan diekstrak dari data Digital Elevation Model (DEM). Sebaran spasial laju erosi tanah di DTA dipetakan dengan menggunakan metode NDVI-slope untuk tahun 2009 dan 2012. Laju erosi tanah di DTA yang dihasilkan dianalisis perubahannya dan diverifikasi dengan membandingkan perubahan laju erosi tanah dengan perubahan koefisien aliran permukaan. Hasil memperlihatkan bahwa laju erosi tanah di DTA mempunyai kecenderungan meningkat, yang sama dengan kecenderungan peningkatan koefisien aliran permukaan selama periode 2009-2012. DTA Danau Kerinci diperkirakan mengalami peningkatan laju erosi tanah, dari 0,39 mm/tahun pada tahun 2009 menjadi 0,46 mm/tahun pada tahun 2012. Kata kunci: Laju erosi tanah, Ekosistem danau, Data satelit multi temporal, Metode NDVI-slope

Abstract

Shore line is important to define seawater administration borders of a province, a district, and a city related to decentralization. The shore line can be extracted from remote sensing data. However, the definition of vertical datum reference for the shore line and low water level place are totally defferent. The sea water level position for shore line used in the hydrographic mapping is mean high sea level (MHSL), while the sea water level for shore line used in the geodetic mapping is mean sea level (MSL). However, remote sensing data were recorded in specific time that also have a specific sea water level, might be in a high or a low sea level depending on the location. Objectives of this research are to understand the position of the sea water level for the shore line mapping when the Landsat 7 is acquired and how to adjust to make a standard shore line definition. The landsat ETM+ compositing of 543 (RGB) Maritime and Navigation Map of 1 : 50.000 scale were overlaid and compared in same condition of spheroid, datum, and projection system. In the area where there is no significant change due to the dynamic of coastal processes, the result of the overlaid image and map indicated that the shore line matched between each other. However, in the area where there are some indicated change, resulted on some differences between the shore line from the image and the map. The sea level position when the image was acquired was in high sea level and the image shore line was as same as the hydrographic shore line. There are two conditions when an image is acquired on a difference water level position. The shore line position would not change in area without 0 meter contour line and would change in area have 0 meter contour line. Adjustment should be made in the second condition.

Abstract

Polarimetric and Interferometric Airborne SAR in L band (PiSAR-L2), yang merupakan kelanjutan dari program PiSAR, bertujuan untuk melakukan eksperimen sensor PALSAR-2 yang akan dibawa oleh ALOS-2. Selanjutnya pada tahun 2012, Japan Aerospace Exploration Agency (JAXA) dan Kementerian Ristek dan Teknologi Indonesia telah melakukan kerjasama riset untuk mengkaji pemanfaatan data PiSAR-L2 di wilayah Indonesia. Penelitian ini bertujuan untuk memanfaatkan kanal-kanal polarisasi data PiSAR-L2 untuk klasifikasi penutup lahan kawasan hutan di Provinsi Riau. Hasil survei lapangan tim JAXA setelah perekaman data PiSAR-L2 dijadikan sebagai data referensi untuk pembuatan training data dan training pengujian hasil klasifikasi. Pengolahan data dilakukan dengan merubah nilai dijital menjadi backscatter (Sigma naught) dan melakukan Lee filter, kemudian melakukan klasifikasi terbimbing dengan metode Maximum Likelihood Enhanced Neighbour dengan 3 perlakuan, yaitu menggunakan input 3 kanal polarisasi SAR (HH, VV dan HV), menggunakan input 3 kanal polarisasi dan 3 kanal tekstur (deviasi HH, deviasi VV dan deviasi HV), serta menggunakan input 6 kanal (3 kanal polarisasi dan 3 kanal tekstur) dan perbaikan training sampel berdasarkan hasil confusion matrix. Selanjutnya dilakukan pengujian akurasi dengan menggunakan metode confusion matrix. Hasil menunjukkan bahwa kanal tekstur dapat menaikkan tingkat pemisahan antara kelas obyek vegetasi, khususnya hutan dan akasia. Hasil klasifikasi dengan menggunakan 6 kanal dan perbaikan training sampel berhasil meningkatkan akurasi klasifikasi penutup lahan sehingga diperoleh nilai overall accuracy sebesar 80% dan nilai kappa sebesar 0.612. Kata kunci: PiSAR-L2, klasifikasi maximum likelihood, Kanal polarisasi, Kanal tekstur, Confusion matrix

Abstract

The aim of this paper is to analyze the spatial distribution of the water discharge in the Ciliwung watershed based on the remote sensing satellite data. Digital elevation model (DEM) is processed to determine the watershed border using the steepest slope method and also used to calculate pixels area. The calculated pixels area are used to determine the watershed and landcover areas in 3 dimension perspective, the landcover of the Ciliwung watershed is mapped by using SPOT-4 image acquired in 2007. All generated information are used as the input to determine the spatial distribution of the water discharge using the run-off coefficient table produced by related institutions. In the next step, the total water discharge in some oulets (Katulampa, Depok and Muara Ciliwung) are compared and the relationship between the landcover condition and the water discharge is evaluated. The result shows that DEM can be used to determine the watershed border and calculate the watershed area, which the results are almost same with the real condition. The spatial distribution of the water discharge is useful to analyse the water discharge contribution of each part of watershed to the total water discharge in the Ciliwung watershed. It shows that the water discharge in Katulampa outlet contributes 44 % of the total water discharge in the Ciliwung watershed. Further, some landcover types are identified in the high water discharge area. This kind of information is very useful for the regional planning and flood management activities.

Abstract

Oil Palm Plantation (Elaelis Guineensis Jacq), in its growth will undergo physical change so that it can be monitored by remote sensing data, that is by observing the influence of age towards spectral band reflectance or indices that can be obtained from Landsat-TM data. The analysis shows Landsat spectral band that correlates with oil palm plantation's age is Band-5 (r=-0.75), Band-7 (r=-0.52), Band-4 (r=-0.50). The indices that correlate with oil palm plantation's age is ratio Band 5/3 (r=-0.71), IRI (r=-0.56) and MIRI-1 (r=-0.48). NDVI and IRI do not correlate with the plantation's age. From the research carried out towards several function froms between age and oil palm plantation a good relationship is obtained on multi-regression linear function (R2 = 0.69), where the equation is: Y=61.3- 0.54 XI + 39.39 X2-42.31 X3, (Xi more than 0), where Y : age, X1=B5, X2=IRI dan X3=MIRI1 (untuk α = 0.05)

Abstract

Total Suspended Matters (TSM) defined all solids or particles with a larger size 1 μm that are suspended in water resulting in decreased quality of water until the water can not be used as intended. There are various methods that have been made in mapping the TSM based on remote sensing satellite data both low and high resolution. This paper describes TSM mapping which TSM algorithm was directly applied to the digital number value of Landsat image. The mapping process was preceded by a thresholding method to separate the water with other objects (clouds, cloud shadows and the mainland), then the TSM concentration was calculated through the algebraic sum of band1, 2.3, and 4 and ended with density slice range process. Based on the TSM analysis, the TSM concentration in the Semangka Gulf was caused by human waste and also the material carried by streams of water from ponds and sewage waste soil erosion. TSM concentration areas was spread out in water of the Wonosobo District until 640 meters of spreading length and Kota Agung Timur districts until 3240 meters of spreading length.

Abstract

Land cover analysis plays an important role in many environmental applications nowadays. The objective of this study is to assess the capability if Moderate Resolution Imaging Spectroradiometer (MODIS) scene for land cover mapping over Nanggroe Aceh Darussalam (NAD) provonce, Indonesia. Standard supervised classification techniques were used in this study namely maximum likelihood, minimum distance-to-mean, parallelepiped and parallelepiped (with Maximum Likelihood Tie Resolution) by using PCI Geomatica 9.1 image processing software. The accuracy of each classification map was assessed using the reference data set consistend of a large number of samples collected per category. The result from this multispectral classification analysis of this study area indicated that urban features could be cleanly identified and classified relative to the surrounding terrain and its associated desert features. In this study, Kappa statistic and overall accuracy were calculated and compared for the three supervised classification technoques. Geometric correction was performed for the digital image using the nearest neighborhood method with second order polynomial. This indicates that land features can be carried out using remote sensing classification method of the MODIS imagery.
