Sumbawa’s Kuris River is one of the rivers contaminated by the island’s traditional gold mine. In order to detect contaminant levels, we examine the magnetic susceptibility, HCN levels, and the heavy metal contents on the river’s surface sediment. Environmental pollution has been widely assessed using a combination of magnetic properties and geochemical analysis. The goals of this research are to discover how magnetic susceptibility (χ) can be used as a first-order proxy for pollution. The relation between susceptibility and HCN is of particular interest, as this is a major contaminant associated with gold mining. The surface sediment samples were collected at ten different locations along the rivers. The magnetic susceptibility was determined using the Bartington MS2B, and the hydrogen cyanide (HCN) concentration was determined using Argentometric titration. The element content was determined by an Atomic Absorption Spectrometer (AAS). The low-frequency magnetic susceptibility (χlf) ranges from 71 to 115×10-8 m3/kg, with an average of 97×10-8 m3/kg, and the χfd(%) analysis ranges from 2% to 4%. The presence of spherical iron oxides, which are indicative of combustion byproducts, was also confirmed by SEM. The samples have low magnetic susceptibility but high levels of Hg and HCN. AAS results showed high Fe, Zn, and Cu concentrations in river sediments, with more variable concentrations of Hg, Mn, As, Cr, and Au. Because Fe, Cu, As, Hg, and HCN have a significant Pearson’s correlation with χfd(%), this parameter can be a useful indicator for contamination caused by gold mining waste.

Abstract Trenggalek is an earthquake-vulnerable area because it is located in the subduction zone of the Indo-Australian and Eurasian plates. Therefore, it is necessary to have the preparedness of the people who live there in order to reduce disaster risk. The Islamic boarding school that was there was also affected by the disaster. Santri have a high risk of experiencing a disaster because they live in the Islamic boarding school. There have been many studies related to the preparedness of the community and school students, but not many studies related to santri’s preparedness. Therefore, the purpose of the study was to analyze the level of santri’s preparedness against the earthquake disaster in Trenggalek. The research method is a quantitative description using questionnaires and interviews. The sample amounted to 30 and was obtained by stratified random sampling. Data analysis uses the earthquake preparedness index. The results showed that 10% were classified as extremely prepared, 35% were classified as prepared, 43% were classified as unprepared, and 17% were classified as extremely unprepared. This happens because of the lack of knowledge of students about the vulnerability of disasters that exist around the Islamic boarding school and the disaster mitigation efforts.

Abstract Floods occur in Sampang Indonesia every year, due to overflowing Kemuning rivers and rising sea levels during spring tide. The morphological conditions which are hills in the middle and syncline valleys in the south with trellis flow patterns with weak and resistant bedrock exacerbate Sampang conditions. This condition increases the threat of urban flooding and rob flooding. One of strategic effort is to know the characteristics and reduce the threat of flooding through Geography subjects in school. Geography teachers as responsible people, act as facilitators and informers who provide knowledge and shape students psychology about flood disasters. Knowledge and participation of geography teachers are very important in flood disaster risk reduction because the teachers are a source of knowledge that is trusted by students. This is a survey research with univariate and multivariate analysis using a quantitative descriptive approach (single frequency and crosstab). The researcher also used inferential analysis in the form of chi-squared to see the relationship of the variables of knowledge and teachers participation in Sampang District. The results of the study indicate that there is a relationship between teachers knowledge and participation in flood disaster risk reduction presented in the learning process. The analysis results show the probability value or Asymp Sig 0.034. so that the knowledge of the geography teachers is very influential.

Abstract Nowadays, disaster learning materials on SMA don’t usea suitable context based on conditions in the field. One of the material should be well understood by the student is flood. Susceptible area toward flood usually lies near coastal area. SampangRegency physically identified as coastal area. It’s spreadthe entire northern part and southern part of Madura Island. This region is exposed by flood every year especially on the rainy season. Typical of a flood could be divided into three kinds; tidal flood, river flood, and combination of tidal and river overflow. The recent flood was triggered by Kali Kemuning. Kali Kemuningspills over every year on rainy season. It affects local inhabitant who lives along riparian and it’s surrounding. Based on Indonesia Statistical Bureau (BPS) data people who exposed by flood in Sampang 1,793 each km2. Its large amount of people became vulnerable. This research was designed in qualitative research. The data is collected by primary and secondary. Primary data was collected from field observation and in-depth interviews. Meanwhile, the secondary data was collected from government institutions; Regional Disaster Management Agency (BPBD), National Disaster Management Agency (BNPB), Inarisk BNPB, andCentral Bureau of Statistics (BPS). The result represents several parts in Sampangthat are susceptible to flooding especially along the coastal area and river riparian. The recent condition in April 2019 showed that the Government build the river wall to reduce flood impact. Local people, insight view toward flood is a usual phenomenon. The condition above explainsthat before learning mitigation material in SMA, the students should understand well how to cope with flood disaster risk.

Abstract Tourism is often associated with magnificence and pleasure. But behind that, tourism is a very vulnerable and fragile economic activity. One of the vulnerabilities that overshadow tourism is the occurrence of natural disasters. In Indonesia, several disasters have caused an impact on the tourism industry, such as the Lombok earthquake that took place in 2018 causing 4,636 tourists to be victims, 100,000 tourists reduced, and losses of 1.4 trillion in the tourism sector. The purpose of this study is to identify tourism area management based on disaster mitigation. This research was designed using qualitative methods. The data collection uses field observation techniques, documentation, and in-depth interviews. The determination of the island of Lombok as a research location is because this region has a variety of interesting natural tourism potentials, such as the Senggigi beach which is located on the west coast of Lombok Island. Senggigi areas have a high earthquake and tsunami vulnerability. Based on research, it is known that Senggigi Beach needs to get more attention in terms of disaster mitigation, such as the making and installation of disaster-prone maps, the addition of evacuation signs, evacuation route maps, shelters, beach belts or buildings as breakwaters, and also monitoring towers. This is useful to provide a sense of security and comfort for tourists visiting the tourist sites.

Tourism is one of the sectors encouraged by the Indonesian government to increase economic growth. one of the efforts made is to establish Labuan Bajo as a national tourism strategic area. This study aims to explain the dynamics of access contested by some actors in tourism governance in Labuan Bajo. A qualitative approach was employed in this study. Data were gathered through interviews, focus group discussion, and document analysis. The results of this study indicate that tourism access is dominated by actors who have the power of capital and they control access to economic circles of the tourism management. On the other hand, societies are unable to involve as the main economic actors around the tourism governance.

The unitary state of the Republic of Indonesia is prone to natural disasters. The loss from natural disasters that occurred was quite large, both in the economic, social and tourism sectors. This requires a company, non-governmental organization (NGO) and the Government to work together to prepare, respond to, and design new effective disaster management strategies. This study aims to determine disaster mitigation efforts and their relationship to cultural tourism areas. Data were collected through literature studies, in-depth interviews, and observations. This study aims to explore disaster mitigation efforts and their links to cultural tourism areas. This research uses a descriptive qualitative approach. Data were collected through literature studies, in-depth interviews, and observations. The study found that disaster mitigation in Segenter Indigenous Village consists of structural and non-structural mitigation. Structural mitigation is based on mechanical mitigation dimensions. Meanwhile, non-structural mitigation includes dimensions of knowledge, values, decision-making mechanisms, and group solidarity. The communities seek disaster mitigation with local knowledge and education or direction from outsiders. The Segenter Indigenous Village community is open to all input as long as it has a positive impact.

This study aims to explain the management of tourism in the Komodo National Park (KNP). Besides, this study portrays the impact of tourism management on the socio-economic life of people living nearby the KNP. This study employed qualitative research methods. The data were obtained from interviews with community leaders, naturalist guides, village heads, tourism managers, fishers, and tourism management communities in the region. Two villages in the KNP were chosen as the data collection sites. The results of this study indicate that the management of tourism in the Komodo National Park area is dominated by the KNP Officer, while the local people exclusively positioned as natularist guide. Besides, this study shows that the existence of tourism in the national park only impacts on people living in the Komodo island region which exclude people living in the island of Rinca from welfare and prosperity.
