“…Figure 3 depicts that the highest emissivity was achieved by vegetated land; while the lowest one was achieved by murky body of water. Juniarti, et al [7] figured out that vegetated land had an emissivity value of 0.99; while body of water had an emissivity value of 0.98.…”

“…Therefore, we needed a research method that might cover a wider area. One of the methods to investigate surface with a wider cover that may map geological information that cannot be terrestrially covered is remote sensing [5][6][7]. Remote sensing is a science to gain information about some particular objects, areas, or phenomena by analysis and interpretation without making any direct contact with them [8,9].…”

The research applied the remote sensing method to map land surface temperature (LST) distribution and geomorphological of Tiris geothermal area (TGA) in Lamongan Volcano Complex. This study was conducted in an area of 73 km 2 covering both TGA and Lamongan Volcanic Field (LVF). The LST distribution was gained by processing thermal infrared images Landsat-8. Geomorphological studies in the study area were done by using 567 bands composite multispectral images Landsat-8 and DEM SRTM data. The geomorphological condition was depicted by visual delineation to the map of 567 band composite and 3D topographical model. The findings argued that the study area had a LST distribution of 15.84℃ to 41.05℃. The hot spots in the study area were mostly located in built-up area and bare land. There was no high LST anomaly seen in the areas near TGA due to influenced by a mixed temperature between hot springs and water flow temperature of Tancak River. Geomorphological findings clarified that in Lamongan Volcano, there were two lineaments leading to the northwest-southeast and northwesteast and there was a fault in TGA leading to northwest-southeast associated with Tancak watershed.

“…The topography of the Ijen Caldera contains many volcanic cones due to magmatic activity [1], so the area's topography allows for the presence of rocks. In the northern part of Mount Ijen, namely the Blawan area, there are various old rocks such as breccia rocks (breccia), basaltic-tuff rocks and lava rocks.…”

Physical properties are the property of a rock after being tasted without damaging the rock. This research aims to describe the physical properties of rocks in Blawan-Ijen, including rock texture, rock density and rock porosity. The method of collecting data is carried out directly, namely conducting direct research in the field and indirect research by conducting library research. The physical properties of the rocks in Blawan-Ijen have a smooth and rough texture, holocrystalline, light and dark colors, and compact. The density value is relatively high, so it has a fairly high density and resistance. In contrast, the porosity value of the rocks in Blawan-Ijen has three categories: poor porosity, very poor porosity, and high porosity. The texture of the rocks in Blawan-Ijen is smooth, holocrystalline, has small cavities and dark in color.

The amount of land built has increased over the years as the population increases. This results in a higher building density, such as in Turikale District, Maros Regency. Each object on the earth’s surface has its distinctive temperature, such as the buildings. The heat of the earth’s surface on certain location points will be captured by the image as an area that has a different surface temperature. The purpose of this study is to determine the temporal-spatial pattern of building density and surface temperature in Turikale Subdistrict, Maros Regency in 2013 and 2018 and is expected to be useful for Turikale District spatial planning and urban environment. Building density data and surface temperature are obtained from Landsat 8 Path 114 row 063 in 2018 and 2013. The data is processed using the Normalized Difference Built-up Index (NDBI) algorithm and Land Surface Temperature (LST) using ArcGIS. Furthermore, an analysis of differences in building density patterns with land surface temperature is analyzed spatially and temporally. The results of the study show that the spatial pattern of building density grows to be higher in density each year, especially in densely populated residential areas and near Jalan Daya-Maros, Turikale District. Temporal patterns of land surface temperatures show significant increases between 2013 and 2018.
