Abstract

potensi pencemaran limbah bahan berbahaya dan beracun (B3). Salah satu bentuk limbah B3 adalah lumpur asam (acid sludge) yang merupakan campuran hidrokarbon dan asam sulfat yang berasal dari proses pembuangan pabrik lilin. Penelitian ini bertujuan untuk mendeteksi daerah tercemar lumpur asam berdasarkan suhu permukaan tanah (Land Surface Temperature/LST) dari data Landsat 7 ETM multi temporal. Tahapan penelitian meliputi pengumpulan data, penyusunan algoritma LST dari data Landsat 7 ETM berdasarkan hasil regresi dengan LST Terra-MODIS, perhitungan LST Landsat 7 ETM multitemporal dan pemantauan LST pada daerah tercemar.  Sebaran nilai LST MODIS dan Brightness Temperature(Tb) Landsat memiliki kemiripan pola sehingga MODIS dapat dijadikan acuan dalam penentuan LST dari Landsat. Untuk penentuan LST dari Landsat telah dibuat model pendugaan dari regresi linier antara LST MODIS dan Tb Landsat dengan koefisien determinasi sebesar 0.84. Berdasarkan analisis LST deret waktu pada daerah tercemar lumpur asam diketahui bahwa daerah tercemar memiliki suhu yang lebih tinggi dibandingkan dengan daerah tidak tercemar.  Tidak terlihat adanya hubungan yang signifikan antara pola LST dengan proses pemulihan lahan yang dilakukan. Hal ini menunjukkan bahwa proses pemulihan lahan tercemar tidak terlalu berpengaruh terhadap suhu lumpur asam di wilayah tersebut.

Abstract

Flood is the most frequent hydro-meteorological disaster in Indonesia. Flood disasters in the Bandung basin result from increasing population density, especially in the Citarum riverbank area, accompanied by land use changes in upstream of the Citarum catchment area which has disrupted the river’s function. One of the basic issues that need to be investigated is which areas of the Bandung basin are prone to flooding. This study offers an effective and efficient method of mapping flood-prone areas based on flood events that have occurred in the past through the use of historical remote sensing image data. In this research, Landsat-8 imagery was used to observe the inundated area in the Bandung basin in the past (2014–2018) using an improved algorithm, the modified normalized water index (MNDWI). The results of the study show that MNDWI is the appropriate parameter to be used to detect flooded areas in the Bandung basin area that have heterogeneous land surface conditions. The flood-prone area was determined based on flood events for 2014 to 2018, identified as inundated areas in the images. The estimation of the flood-prone area in the Bandung basin is 11,886.87 ha. Most of the flood-prone areas are in the subdistricts of Rancaekek, Bojongsoang, Solokan Jeruk, Ciparay, Cileunyi, Bale Endah and Cikancung. This area geographically or naturally is a water habitat area. Therefore, if the area will be used for residential, this will have consequences that flood will always be a threat to the area.

Abstract

The solid form of oil heavy metal waste is  known as acid sludge. The aim of this research is to exercise the correlation between acid sludge concentration in soil and NDVI value, and further studying the Normalized Difference Vegetation Index (NDVI) anomaly by multi-temporal Landsat satellite images. The implemented method is NDVI.  In this research, NDVI is analyzed using the  remote sensing data  on dry season and wet season.  Between 1997 to 2012, NDVI value in dry season  is around – 0.007 (July 2001) to 0.386 (May 1997), meanwhile in wet season  NDVI value is around – 0.005 (November 2006) to 0.381 (December 1995).  The high NDVI value shows the leaf health or  thickness, where the low NDVI indicates the vegetation stress and rareness which can be concluded as the evidence of contamination. The rehabilitation has been executed in the acid sludge contaminated location, where the high value of NDVI indicates the successfull land rehabilitation effort.

Abstract

Green open space becomes critical in maintaining the balance of the environment and improving the quality of urban living for a healthy life. The use of remote sensing data for calculation of green open space has been done notably using NDVI (Normalized Difference Vegetation Index) method from Landsat 8 and SPOT data. This research aims to calculate the accuracy of the green open space classification from multispectral data of Landsat 8 and SPOT 6 using the NDVI methods. Green open space could be assessed from the value NDVI. The value of NDVI generated from Landsat 8 and SPOT 6’s Red and NIR channels. The accuracy of NDVI values is then examined by comparing with Pleiades data. Pleiades data which has 50 cm panchromatic resolution and 2 m multispectral with 4 bands (B, G, R, NIR) can precisely visualize objects. So, it can be used as the reference in the calculation of the green open space based on NDVI. The results of the accuracy testing of Landsat 8 and SPOT 6 image could be used to identify the green open space by using NDVI SPOT of 6 can increase the accuracy of 5.36% from Landsat 8.
