Abstract

The assessment of potential disasters is a critical sectoral problem. Because hazard can damage and harm to people. The purpose of this research is to identify potential disasters in Parangtritis area. The identification based on the appraisal variables on some of the multi-hazards that may arise and threaten in this area based on the characteristics of the landform such as gisik, fluvio-marin plain, hills, alluvial plains, and others. This study includes exploratory and evaluation research with a qualitative approach. The results showed some potentially catastrophic hazards in the Parangtritis area, including tsunamis, abrasion, landslides, and floods. Each potential risk has a different level of insecurity and location distribution.

Abstract

Kecamatan Pagak, Kabupaten Malang is an area which is dominated by karst landform. Basically, Karst is landform which is vulnerable to drought for the very minimum of waterflow surface.  Underground river flows are more developed in karst landforms due to the large number of fractures. Based on these problems, this research seeks to solve the problem of water crisis in karst landforms by utilizing groundwater. It chose geomorphological approach to find the highly potential groundwater landforms so that these they can be used as groundwater infiltration zones. Geomorphological mapping is carried out by identifying aspects of morphology, morphogenesis, morphoarrangement, and morphocronology. Through the geomorphological mapping, it was obtained nine units of landforms in the research area. The P4Fv1 landforms are units that have high groundwater potential which can be utilized in large quantities.

Abstract

This study aims to create awareness of disasters in class X students by utilizing the Mind Mapping learning model on disaster material. The method used in this research is descriptive qualitative using literature study analysis. The results obtained from this study are a Mind Mapping learning model that is able to generate awareness of disaster in earthquake material in students. The developed media has never been tested on students so that it becomes a recommendation for further research.

Abstract

Forest fire is a hazard that common to happen in Indonesia every year, whether from natural or human-induced factor. These fires can be uncontrollable and destruct the forest. Furthermore, these can affect the health of the people, the biodiversity, the disruption in transportation and the socioeconomic of the affected region. The total area calculated was burned is 875.756 hectares in the entire country in 2019, the biggest lost after 2015. Thus, the study conducted in some affected area in Riau Province, Sumatra, Indonesia where consistently suffered from the fire by remote sensing and GIS approach. The study of the burned area was investigated using a formulated index called NBRI (Normalized Burn Ratio Index) based on Near Infrared (NIR) and Shortwave Infrared (SWIR) spectral reflectance of Landsat 8 OLI/TIRS Satellite Imageries. The two values of NBRI from post and pre-fire images were calculated to define differenced NBR (dNBR) to assess its severity. It is found that about 4,7 %, or about 11.014 hectares of the area of the study which was about 234.864 hectares was burned. 90,3 % of the burned area was located in the vegetated area, especially forest area with 50,25 % of those cover the burned area. The validation was using visual interpretation based on SPOT 7 pansharpened images resulted in acceptable agreement with kappa coefficient value of 0,83. The information on the maps can be used to develop rehabilitation planning or predict the area for potential fire hazard in the future.

Abstract

Anak Krakatau is one of the legendary mountains which was the result of the eruption of Mount Krakatau in 1883. The Krakatau area was divided into three regions, Krakatau Island, Sertung Island, and Mount Anak Krakatau. The activity of Mount Anak Krakatau in 1929 tended to be active, because in a year Anak Krakatau could experience eight eruptions. This can be seen in visual observations starting from 1929-2000 experiencing a fairly rapid development. At the end of 2018, Anak Krakatau erupted again, where the eruption caused a landslide to part of the mountain's side. As a result, the debris from the landslide, made the waters of the Sunda Strait unstable, thus forming a tsunami wave. Eruption did not only happened in 2018, Recently, Anak Krakatau became active again in 2020 by releasing its volcanic ash. The activity of Anak Krakatau which underlies the purpose of this study, namely knowing the formation process and activities of Mount Anak Krakatau. So that in the future further research can be carried out related to disaster mitigation efforts from the eruption of Mount Anak Krakatau in the area around the mountain. The analysis process used is a literature study using related journal articles and data on the cataclysmic events of the Anak Krakatau volcano eruption.

Abstract

Kalijati sub district is a district with the largest land area is 1002.96 m2 and the number of people at most that 536 people affected by the construction of toll roads Cikampek-Palimanan. In general, the condition of the land affected by the construction of the toll road is a residential area and garden. Based on the authors wanted to examine the effect of highway construction Cikampek-Palimanan on the socioeconomic conditions that include livelihood, income, and ownership of community residences district of Kalijati after land acquisition.

Population sample as many as 85 landowner. The sampling technique used in this study is proportional random sampling. Variables consisted of independent variables which include land, land prices, land types and the dependent variable consisted of socio-economic conditions. Instruments in the study comprised interviews and questionnaires. Data analysis using Chi-square and contingency. The results showed no effect of highway construction Cikampek-palimanan the principal livelihood and sideline, this is due to land in the District Kalijati land use average form settlements and gardens, in addition to the District of Kalijati few people who use the proceeds from the sale of land for opening a new business, for example opening a store or make a contract, There are significant road construction Cikampek-palimanan to influence people's income shows the value by 21% because the affected area is the construction of toll roads productive land and and there are significant road construction Cikampek-dwelling palimanan to show the influence of ownership by 32% because of the sale of public land use average to build and repair houses. Thus the construction of toll roads Cikampek-palimanan the socioeconomic conditions of the people in District Kalijati not have influence on the principal livelihood and livelihood while the side shows the influence of the income and ownership of residence in District Kalijati.
