Abstract

The peat fire events in Indonesia, particularly the South Sumatra area, changed the appearance of surface vegetation. The fires usually occur during the dry season from July to October. This study aims to evaluate land cover changes due to 2015’s peat fire in the South Sumatra peatlands. Remote sensing techniques using a Normalized Difference Vegetation Index (NDVI) method were used to identify the change of vegetation density in the study area. The results showed that 69% of the total South Sumatra peatland was burned due to the 2015 peat fire event. The level of vegetation density was considerably decreased by fire events. The degradation in the burned area was dominated by land cover class of ferns/shrub. The Peat fires during the observation period have a negative impact on the peat ecosystem, so improvements are needed in peatland management practices. Improvements need to be made in fire prevention and management practices, as well as restoration of burnt land.

Abstract

Photogrammetry has become a trend in large-scale mapping today. The ability to produce large-scale geospatial products in a relatively short time and low cost is very beneficial for mapping. The ability of high temporal and spatial resolution also makes photogrammetry used in the disaster mapping process. In this study, the DEM approach from photogrammetry was used for input data in tsunami run-up modeling activities in Way Muli Village. High temporal and spatial capabilities are utilized for the production of surface roughness and elevation which are key parameters for rigorous inundation modeling. The modeled inundation results show that the run-up limit achieved in residential areas is on the main road with a maximum distance of inundation from the shoreline is an average of 80 m. The results obtained can be used by the village government to preparedness in dealing with the tsunami.

Abstract

Satellite-derived bathymetry (SDB) is one of the techniques in remote sensing for extraction of ocean depth by utilizing optical imagery. Spectral data from the water column is needed for SDB process. One of SDB method is an analytical method requiring field spectral data, water attenuation, and water constituents for depth estimation processes. Spectral data and attenuation were acquired by TriOS Ramses spectrometer. Water constituents are taken from filtered water samples to be tested at the laboratory. The water constituents tested were chlorophyll, CDOM, TSS, and TOM. The depth value of bathymetry extraction is strongly influenced by light penetration behavior. This is influenced by the condition of water constituents. Water constituents affect the attenuation of water. The study gives results from 4 stations of attenuation measurement having a positive correlation with chlorophyll constituents. Chlorophyll has a positive correlation with other constituents (TOM, CDOM, and TSS). From the value of water attenuation, the water classification around Karimunjawa Port are clear water of type III and 1 which have a value of (PAR) is 0.111 m-1.

Abstract

Sesar Semangko dengan panjang 65 km merupakan wilayah yang aktif secara tektonik dan terletak di Provinsi Lampung. Sesar Semangko terbagi menjadi dua: Sesar Semangko Barat dan Sesar Semangko Timur. Segmentasi sesar Semangko Timur terlihat terputus dari citra satelit dengan resolusi spasial 30 meter ketika melalui Kota Agung karena terjadi sedimentasi. Penelitian ini bertujuan mendapatkan segmentasi sesar Semangko Timur menggunakan pengukuran fotogrametri dengan resolusi spasial yang jauh lebih baik dibandingkan citra dari satelit. Data yang digunakan adalah data pengukuran fotogrametri dan Global Navigation Satellite System (GNSS) di wilayah dengan luas 100 hektar di lokasi terputusnya sesar Semangko Timur di Kota Agung, Tanggamus. Pengukuran fotogrametri dilakukan dengan menggunakan tinggi terbang sebesar 100 meter. Segmentasi sesar dilakukan dari DSM hasil pengolahan fotogrametri dengan mendefinisikan perbedaan nilai kelerengan di sesar Semangko Timur sebelum terputus dan diterapkan di lokasi penelitian dengan ciri serupa. Nilai kelerengan diperoleh dengan pembuatan kontur dari DSM. Kualitas produk DSM hasil pengukuran fotogrametri mencapai 12,4 cm untuk ketelitian horizontal dan 36 cm untuk ketelitian vertikal. Segmentasi sesar Semangko Timur yang tergambarkan dengan pengukuran fotogrametri yaitu sepanjang 100 meter di tutupan lahan persawahan.

Abstract

Maninjau Lake is one of Indonesia's lakes for hydroelectric power plants, tourism, and fish farming activities. Some activities around the lake cause pollution, leading to massive fish kill. Therefore, it is necessary to monitor water quality regularly. One of the critical water quality parameters is biochemical oxygen demand (BOD). This study aimed to analyze BOD changes using a remote sensing approach during massive fish kills in Maninjau Lake, Indonesia. Multi-temporal Landsat-8 satellite images are processed to estimate the BOD level based on Wang Algorithm. After that, the estimated BOD value is validated using in situ data measurement. The results of the average BOD concentration that occurred in Lake Maninjau was 1.85 mg/L and showed that R2 was 0.8334, and the standard error was 0.076 between the estimated BOD and in situ data. Furthermore, the average concentration of BOD obtained on 23rd August 2017, 13th December 2017, 30th January 2018, 19th March 2018, and 7th July 2018 are 4.96 mg/L, 4.82 mg/L, 5.31 mg/L, 6.94 mg/L, and 6.60 mg/L, respectively. Increased BOD concentration in January 2018 indicates moderate pollution in the waters. BOD concentration increases after the massive fish kill due to the decaying fish across the lake.

Abstract

Dalam upaya mendukung pengembangan program Desa Agroforestri berbasis Informasi Geospasial di Desa Girimulyo, penting akan adanya data dan informasi yang berbasis geospasial. Masih kurangnya ketersediaan data dan informasi menjadi salah satu kendala terbentuknya program tersebut. Oleh karena itu kegiatan tersebut akan memerlukan data dan informasi spasial sebagai data utama dalam pengambangan program agroforestri dengan mengangkat bibit unggulan lokal yaitu Alpukat Siger. Pemanfaatan teknologi fotogrametri menjadi salah satu solusi yang tepat mengingat proses pemotretan wilayah dapat dilakukan dengan ketelitian yang tinggi (resolusi spasial tinggi). Meski sebelumnya sudah pernah dilakukan pemotretan foto udara wilayah Desa Girimulyo, tetapi masih ada sebagian kecil dari wilayah keseluruhan yang belum dilakukan pemotretan. Sebagai desa binaan dari Program Studi Geomatika ITERA, tim pengabdian akan membantu menyediakan data berupa peta foto udara yang sebelumnya masih terbatas hanya beberapa dusun. Hasil dari kegiatan ini berupa peta foto udara Desa Girimulyo yang dapat digunakan sebagai Informasi Geospasial Dasar (IGD) untuk mendukung kegiatan apapun, khususnya pengembangan program desa agroforestri.

Abstract

Traditional forest inventory methods for obtaining tree stand data in the Batu Serampok Protected Forest Management Unit (KPHL) require significant time and resources. Therefore, remote sensing technology was employed to estimate the potential tree stand density. This study utilized the Forest Canopy Density (FCD) model and the Normalized Difference Vegetation Index (NDVI) from SPOT-6 satellite imagery to assess forest density. Field surveys were conducted to validate the image processing results. Statistical analysis, including correlation and linear regression tests, was performed. Forest density classes were converted into the number of trees per unit area using regression equations. Accuracy tests compared field data with estimated tree stand counts based on vegetation indices. The FCD correlation score was 0.85, higher than NDVI's 0.78, with linear regression results of 0.73 for FCD and 0.62 for NDVI. FCD demonstrated higher maximum accuracy (90.52%) compared to NDVI (84.08%), making it the preferred method for estimating tree stand potential. Overall, FCD reconstruction proved more accurate than NDVI, with the Batu Serampok KPHL predominantly characterized by moderate-density stands.
