Abstract

the population. This s tudy aims to determine how large the extent of land-us e change that occurred in the Dis trict of Palolo within 13 years (2003-2016), as well as determine the potential for lands lides in the Dis trict of Palolo due to land -us e changes that occur. The res earch location is in the Dis trict of Palolo, Sigi Regency. Res earch data included: LANDSAT 8 imagery, RBI Palolo map, DEM s lope data, rainfall, geological type, s oil type, and population dens ity. The method of data collection is done by indirect obs ervation and calculation by Geographic Information Sys tem (GIS) analys is , as well as us ing the Qua ntum GIS (QGIS) application and documentation s tudy. The method of data analys is is done us ing image interpretation analys is , s caling, coding, overlay techniques , and des criptive analys is . The res ults of the s tudy s how that land-us e changes that occurred in 2003 to 2016 covered 47,366.81 hectares of the total area of Palolo Subdis trict, which was 64,710.21 Ha or 73.2%. Areas with moderate and high levels of potential lands lide dis as ters are more prevalent in areas that experience less intens ive land-us e change (IC). The area referred to can be s een from the A2-KI-B1 land unit covering 18,013,279 ha or 38.02%, and the A3-KI- B1 land unit covering 10,491,693 ha or 22.15% of the total area that has changed ie 47,366.81 ha. This s hows that the occurrence of lands lides in the Palolo s ub-dis trict was caus ed more by the weather (high rainfall) in the Palolo s ub-dis trict.

Abstract

Air is a mixture of gases found in the layer that surrounds the earth. The cokriging method is the development of the kriging method to estimate a variable that minimizes estimation errors by utilizing cross-correlation between several variables. This research was conducted using data from 45 coordinate locations for air monitoring by the Department of Environment and Forestry of the Special Region of Yogyakarta in 2017. The results showed that the best model for estimating sulfur dioxide and nitrogen dioxide air pollution was the spherical model with the smallest Mean Square Error (MSE) value. which is 317,527. Interpolation of sulfur dioxide and nitrogen dioxide content values using cokringing resulted in 100,390 new points. The value of air pollution is in the range of 0-40, which according to ISPU means that at that point, good air quality has no impact on humans but causes a certain smell and injury to some plant species.

Abstract

Infrastructure plays an important role in improving the quality of life and human welfare. Infrastructure is a facility that is needed by every country, including Indonesia, to support various community activities in general in everyday life. However, the problem of inequality in infrastructure development in Indonesia is still a challenge for the government. This study aims to classify provinces in Indonesia based on indicators of infrastructure development. The method used in this grouping is the ward method with the multiscale bootstrap approach to determine the validity of the formed cluster. The results of the grouping show that we obtained 7 clusters where clusters with poor infrastructure development status are cluster 7, clusters with fairly good infrastructure development status, are cluster 6, clusters with good infrastructure development status, are cluster 1, cluster 2, cluster 3 and cluster 4, while cluster with a very good infrastructure development status, are cluster 5. From the 7 clusters formed, we obtained 4 clusters with an approximately unbiased (AU) value greater than and equal to 95, defined as valid clusters and 3 clusters with an AU value of less than and equal to 95, defined as invalid clusters

Abstract

The Palu City area is one of the areas that are vulnerable to the impact of the earthquake, seen from the seismicity and the Palu-Koro fault. Therefore, it is necessary to analyze the seismic vulnerability index and the thickness of the sediment layer in the Palu city area. This study uses the microtremor method with HVSR (Horizontal to Vertical Spectrum Ratio) analysis. The HVSR method produces natural frequency parameters (fo) and amplification (Ao) which are presented in the form of an H/V curve so that this method can estimate the seismic vulnerability index (Kg). The H/V then becomes the input for the ellipticity curve analysis to get the thickness of the sediment layer (h). The results of the study show that the Kg value ranges from 0.16 to 37.09. The lowest Kg value is located at the point MP2234-14 (Kawatuna Village). ) and the highest Kg value is located at MP2234-06 (Petobo Village), the high Kg value tends to be in the valley area and areas close to the coast, while the hillside tends to be low. The results of the analysis of the thickness of the sediment layer (h) ranged from 7 m to 128 m, the thick sediment layer is in the valley and coastal areas, while the thin sediment layer tends to be in the area oh the hills
