Abstract

The Merapi volcano is the most active volcano in Indonesia until now, because of eruption occur every two or five years. To minimize the impact of volcanic eruptions need to monitor the volcanic activity, one effort in monitoring is to monitor the surface changes (deformation) around the volcano. These surface changes can be monitored with InSAR technique. In this study monitoring by analyzing the Digital Elevation Model (DEM) and displacement map from result processing using InSAR technique. The accuracy of DEM compare with Shuttle Radar Topography Mission (SRTM) DEM. These results showed that after the eruption in 2006 led to the deflation that occurred in 2007. In 2010 after the eruption led to deflation in some areas of Merapi volcano. Whereas in 2008 due to the absence of volcanic activity that occurred then the deformation is not so large changing. Test on the DEM from the process of InSAR compare with SRTM DEM produced an accuracy of 96%.

Abstract

The growth of tourism in the Nusa Penida Tourism Area has an impact on the socio-cultural environment due to the development of tourism supporting facilities and infrastructure. Socio-cultural spaces also experience pressure due to conflicts of interest in the use of sacred areas for tourism, resulting in a process of desacralization. Social interactions are declining and arrogance is increasing at some tourist attraction points. Some physical spaces have become economic spaces. Road border, roadside, coast have become economic space. The way of thinking has been hegemony by the interests to get more economic access. The construction of the mind is filled with capitalist desires. Arrogance and ego between groups began to be seen in each particular area. The narrowing of social and cultural space has increased the critical power of the community towards the use of the area, especially spaces that are related to religion. Fighting egoism and social cultural conflict to catch up with the material culture. The social and cultural life of the Nusa Penida people is forced to adapt to material cultures. So fast tourism to Nusa Penida leaves the mindset, knowledge and culture that has been developing in the Nusa Penida community.Keywords: impact; social; culture; tourism; nusa penida

Abstract

Nusa Penida is part of the Province of Bali which consists of three small islands, namely Nusa Penida Island, Nusa Lembongan and Nusa Ceningan within the administrative area of Nusa Penida District, Klungkung Regency. The development of tourism in Nusa Penida has increased access to physical development and supporting facilities for the region. The leap of development of tourism facilities began to be felt starting in 2005, namely on the islands of Nusa Lembongan and Nusa Ceningan. The development of massive tourism facilities took place in 2015 until 2019 since the 2014 Nusa Penida Festival was held. Many coastal and inland areas were built with tourism accommodation, which naturally led to land conversion and land depreciation. The purpose of this study was to determine land use change from 2003 to 2019 using the overlapping analysis method of Google maps and maps derived from quick bird imagery. Transfer of land functions in the Nusa Penida Region from 2003 to 2019 reached 164.84 ha or the rate of land use change that occurred in the Nusa Penida Region was 0.85%.

Abstract

Rainfall erosivity is a measure for the erosive force of rainfall. Rainfall kinetic energydetermines the erosivity and is in turn greatly dependent on rainfall intensity. Research hasbeen conducted to validate monthly rainfall erosivity derived from the Tropical Rainfall MeasuringMission (TRMM) Multisatellite Precipitation Analysis(TMPA)3B43 version 7 usingraingauge data analysis from 2003 to 2012. Rain gauge located in the south Bali regions wereemployedto monitor erosivity value from two different methods that are base on Bols (1978)andAbdurachman(1989). Therelationship of erosivity and their other factor from TRMM3B43andrain gauge data statistical analysis measures consisted of the linear correlation coefficient,themean bias error (MBE), and the root mean square error (RMSE). Data validation wasconductedwith point-by-point analysis. The results of these analyses indicate that satellitedatahave lower values than the gauge estimation values. The point-by-point analysis indicatedsatellite data values of high to very high correlation, while values of MBE and RMSEtendedto indicate underestimations with high square errors. Moreover,monthly rainfall erosivityderived from TRMM give high correlation from both methods, with has high bias androot-mean-squareerror. In general, the data from TRMM3B43 version 7 are potentially usabletoreplace rain gauge data based on erosivity estimation, but after inconsistencies and errorsaretaken into account.

Abstract

High population density is the main factor in environmental problems, where the high speed of human growth caused the vegetation area became deminishing. The aims of this research was to functionized the ALOS/AVNIR-2 image satellites and GIS to calculate the percentage of vegetation in Denpasar city with three index vegetation formulas: NDVI, SAVI dan MSAVI in order to get one formula to build the distribution map based on the percentage of vegetation. This map was used to evaluate the urban planning map 2003 in Denpasar city. Result showed that there was relationships between vegetation index of ALOS/AVNIR-2 images and percentage of vegetations, where the vegetation index of NDVI and SAVI had the highest coefficient determination. The formula of “Percentage Vegetation = 132.71 (NDVI)2 + 3.461 (NDVI) + 5.6775” was used to generate the percentage distribution vegetation map. Based on that map, the dominant vegetation distribution found in settlement area (with percentage vegetation area) lower than 25%. The urban planning for green open area “KDB” 0% was dominated by the area which had a percentage of vegetation between 25-50% and 50-75%. In the other hand, the urban planning for “Tahura”, was dominated by the area which had a percentage of vegetation of more than 75%.

Abstract

Development in ??Batur UNESCO Global Geopark which has an area of ??19,422.39 ha has increased significantly in recent years. The existence of limited land and to know the suitability of land use, it is necessary to evaluate of land use with regional spatial plan (RTRW). Landsat 8 satellite remote sensing data on 27 September 2017 is used to create land use maps. Land use maps obtained through the process of image classification using supervised classification method and verified by ground check. From this technique result 11 classes of land use. Furthermore, to evaluate of land use suitability was conducted by comparing land use with regional spatial plan (RTRW). In this process, there is an overlay between the land use maps with regional spatial plan (RTRW) map using geographic information system (GIS). The results of evaluation land use in Batur UNESCO Global Geopark with regional spatial plan (RTRW) overall has suitable area 10,863.14 ha (55.93%), not suitable area 8,275.58 ha (42.61%) and not detected/cloud interference 283.67 ha (1.46%).
