Disaster risk refers to the possibility of a loss of life, assets, health, and livelihoods to the community in the future, so it must be reduced, one of which is by implementing disaster risk management. The disaster risk management financing scheme is crucial considering the number of funds needed. This research serves as an initial exploration into alternative funding options by investigating the potential benefits of implementing the Land Value Capture (LVC) scheme. The driving question of this study focuses on the advantages of employing the land value capture concept for disaster risk funding. To address this question, a descriptive qualitative research methodology is employed, encompassing an analysis of LVC in general, a funding analysis for disaster risk management, and the implementation of LVC for disaster risk reduction specifically in Indonesia. The findings of this study reveal that the Land Value Capture (LVC) scheme can serve as an additional strategy for funding disaster risk management in Indonesia. Through the proposed framework, the integration of LVC with disaster risk financing and insurance is facilitated.

The 2018 earthquake in Palu highlighted the city's vulnerability. For this reason, disaster mitigation efforts were needed to reduce the impact of disaster. Disaster mitigation can take the form of formulating human rights-based spatial policies. The government is obliged to protect, respect, and promote human rights. The rights that must be protected in the formulation of spatial planning policies are the right to information, the right to participate, and the right to justice. This study aims to determine why disaster mitigation efforts through spatial planning policies are important for local governments to undertake and what form the responsibility of local governments in disaster mitigation efforts through human rights-based spatial planning policies in Palu City takes. This study used qualitative research methods. The data obtained comes from primary and secondary sources. Primary data includes excerpts from interviews with stakeholders and observations, as well as laws and regulations. Secondary data include scientific articles published in various accredited national journals and reports from relevant state agencies and institutions. The results of this study found that mitigation through spatial planning policies based on human rights is important to be done because, in addition to reducing the impact of disaster, it also ensures that people's rights are not violated. Through this spatial planning policy, the community can identify potential threats of disaster to their residential areas, allowing them to make informed decisions about their future quality of life in that area. Furthermore, active community participation in the implementation of this policy is encouraged to reduce the impact of future disasters. It is hoped that other regions, especially those prone to disaster, can also apply the concept of disaster mitigation through human rights-based spatial planning policies based on the results of this research.

Anak Dalam Tribe (ADT) is an indigenous community living inside the conservation area, protected as cultural heritage. ADT family is highly dependent on the forest, they used to live and fulfill all their needs from the forest. Now with the modernization and regulatory dynamics taking place, ADT family undergoes changes as a form of adaptation, leading to residing categorization i.e. traditional, transition, and bediom. The changes impact on the ecological transactions thus bring a greater potential risk of forest fires, as has happened in recent years. This study aims to discover ADT family ecological transactions based on their residing type so that potential environmental exposure can be predicted and anticipated for disaster risk reduction. The qualitative research was conducted using a cross-sectional method. Data were collected through in-depth interview, observation, and forum group discussion. Mapping was done to understand the transaction pattern. This study found that the pattern of each kampong was different, showing that development has happened following the socio-ecological changes of each kampong, either by nature or intervention from outside parties. However, the livelihood area is still the biggest and outermost area of all six kampongs despite the residing type, covering the forest area. Moreover, the area of exposure is enlarged. It vindicates the escalating disaster risk. It is suggested to create a holistic livelihood ecosystem for ADT near their residing place to minimize the disaster risk. Political identity of ADT also should be reconsidered, with the inevitable global development, how far the heritage should be kept.
Anak Dalam部落(ADT)是生活在保护区内的土著社区，作为文化遗产受到保护。ADT家族高度依赖森林，他们过去的生活和满足他们所有的需求都来自森林。随着现代化进程的不断推进和调控的不断深入，ADT家族作为一种适应形式也在发生着变化，从而形成了传统、过渡和自由的分类格局。这些变化对生态交易产生了影响，因此增加了森林火灾的潜在风险，这是近年来发生的事情。本研究旨在发现基于居住类型的ADT家庭生态交易，以便预测和预测潜在的环境暴露，以减少灾害风险。质性研究采用横断面法进行。通过深度访谈、观察、论坛分组讨论等方式收集数据。进行映射是为了理解事务模式。这项研究发现，每个乡村的模式都是不同的，这表明发展是随着每个乡村的社会生态变化而发生的，无论是自然的还是外部各方的干预。然而，尽管是居住类型，生计区仍然是所有六个甘榜中最大和最外围的区域，覆盖了森林地区。而且，曝光面积增大。它证明了不断升级的灾难风险。建议在其居住地附近为ADT创建一个整体的生计生态系统，以最大限度地降低灾害风险。ADT的政治认同也应该重新思考，随着全球化发展的必然，这种遗产应该保留到什么程度。

Changes in transportation trends can occur during and after COVID-19, such as travel distance, trip, and choice of transportation mode. The positive benefits from these changes in transportation trends should be maintained, to reduce disaster risk of environmental hazards from the CO2 emissions. Research on changes in mobility, trips, and CO2 emissions during and after COVID-19 in Indonesia is still very limited; whereas, changes in these transportation variables can be an inspiration for determining sustainable transportation policies in the future. This study aims to compare amid COVID-19 and post-COVID-19 transportation variables—travel distances, trips, and associated CO2 emissions. This research was conducted by giving questionnaires to 400 participants in Aceh Besar District. The questionnaire contains questions regarding the distance traveled, trips, fuel spent, and socio-economic characteristics. The CO2 emissions were calculated using IPCC (2006). The travel distance, trips, and transportation-related CO2 emissions during and after COVID-19 were compared respectively based on statistics. The results showed that there were significant differences in travel distances, trips, and transportation-related CO2 emissions between COVID-19 and the post-COVID-19 situation in the District of Aceh Besar. This article also presents several recommendations based on the data analysis results linked to literature studies about the sustainability of transportation as a result of COVID-19 situation; those are: providing quality public transportation, considering teleworking, providing solutions for workers who do not have access to online work, and paying attention to increasing use of private cars and car sharing post COVID-19.

Flooding may occur due to dam failure at downstream of the spillway. Stilling basin of the spillway plays an important role in reducing turbulence generated by hydraulic jumps. It can avoid flooding and local scouring as well. Therefore, this study aims to analyze hydraulic jump characteristics experimentally. Two series of structures namely initial (S0) and final (S1) were tested. The S0 model is the United States Bureau of Reclamation (USBR) III type, while S1 is set the adverse slope of 1:2 at the downstream and lowering the bottom elevation of the channel by 4 m. Measurements were taken on the length of hydraulic jumps, water level and high speed before-after hydraulic jumps at various return periods discharges (Q) of 2, 5, 10, 25, 50, 100 and 1000 years. It is found that at S1, the jump is submerged, causing the relative hydraulic jump height (y2-y1)/y1 to be 40-90% higher than S0. Furthermore, the compression of more than 50% of the hydraulic jump length ratio (Lj/y2) was indicated at S1. In addition, the energy dissipation efficiency (εt) obtained for each discharge at S1 ranged from 58-84% (good absorption). On the other hand, at S0, the εt produced was around 70-89% (Q2-Q50) and 45% (Q100 and Q1000). It can be concluded that the modification of USBR III can reduce the vulnerability of the bottom and downstream parts of the stilling basin. It is expected that the potential flood disaster due to the stilling basin failure of the dam can be eliminated. These results may be used as recommendation to the disaster management strategies, such as improving dam safety guidelines, informing emergency response plans, or guiding infrastructure design to withstand hydraulic forces.

Ground movement is one of the most frequent disasters causing major damages in Indonesia. Unmanned Aerial Vehicle (UAV) has been widely used as a rapid observation method to obtain detailed characterization of ground movement. Often, active landslide area is difficult to access. This hinders close monitoring and observations of the ground movement. This study aims to demonstrate the use of UAV as tools for monitoring and observations on active ground movement area and to validate the results. For this purpose, the study was conducted at Gampong Lamkleng, Aceh Besar-Indonesia using spatio-temporal analysis by UAV photogrammetry. The UAV was chosen because it is easy to use, practical, and safe for landslide area that are relatively small and difficult to reach. Aerial photographs were processed using the Agisoft Metashape software in modeling and analyzed using Quantum GIS (QGIS) and ArcGis. The observation results show that the largest ground movement occurred in January 20 to 23, 2021 which was related to precipitation rates measured at a nearby rainfall station. The movement volume was 1,411.063 m3 and a rate of ground movement reaching 0.69 m/day due to heavy rain. The estimated value of losses is IDR 1,055,854,000. The UAV images analysis were compared to actual ground elevation measured using Real-Time Kinematic (RTK). The validation show that the accuracy based on comparison between photogrammetric and RTK measurement was at agreeable rate (99%). Otherwise, the accuracy performed on 19 check point using Root Mean Square Error analysis found that the accuracy was still very low. The low RMSE value is due to the georeferencing process using the Ground Control Point not being carried out.

The movement volume was 1,411.063 m3 and a rate of ground movement reaching 0.69 m/day due to heavy rain. The estimated value of losses is IDR 1,055,854,000. The UAV images analysis were compared to actual ground elevation measured using Real-Time Kinematic (RTK). The validation show that the accuracy based on comparison between photogrammetric and RTK measurement was at agreeable rate (99%). Otherwise, the accuracy performed on 19 check point using Root Mean Square Error analysis found that the accuracy was still very low. The low RMSE value is due to the georeferencing process using the Ground Control Point not being carried out.","PeriodicalId":153413,"journal":{"name":"International Journal of Disaster Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128674329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is predicted that Indonesia will soon serve more than 140 million passengers a year. However, the safety records of the aviation industry have not shown a significant progress. Airlines operated in Indonesia has repeatedly experienced serious accidents killed hundreds of passengers and crew. The purpose of this study is to explore corporate communications related to safety culture. This study is concerned with the ideological role played by language in the discursive construction of safety culture. Using Thompson’s (1990) schema regarding the modes of ideology, this study analyzes annual reports of two airlines operated in Indonesia published in the last fourteen years to establish the linguistic strategies used in their communications related to safety culture. The results suggest that the companies used particular linguistic strategies in their communication of safety culture to advance the worldviews of economic efficiency and cost control based on capitalist logic. The prioritization of business growth may contribute to avoiding allocating resources on aspect that is matter most. Given high expectation of safety standards of the aviation industry, the findings have clear and significant implications. It is recommended that aviation industry must improve their safety cultures to prevent unnecessary accidents in the future.

Based on the National Disaster Management Agency, there was an increase in the total number of disasters from 2020 to 2022, which was initially 1,296 to 5402 disasters, with the highest percentage of disaster events being flood disasters with the highest frequency being in the West Java and DKI Jakarta areas (BNPB, 2022). The high frequency of floods that occur in the West Java region can certainly increase economic losses that are pretty high. On the other hand, West Java Province also contributes the third most significant national GDP. The sector that contributes the most to West Java's GRDP is the processing industry sector (BPS, 2017). Karawang Regency is one of West Java's destination areas for industrial development. In Karawang Regency, industrial areas are developing quite rapidly and are concentrated in the southern part of Karawang Regency (Telukjambe Barat, Telukjambe Timur, Ciampel, Pangkalan, Klari, and Cikampek districts). However, based on research conducted by the ITB Climate Change Center (2022), several points have a relatively high level of flood hazard in the area. That can bring considerable losses if the disaster occurs in an industrial area, so an analysis of losses due to flooding is needed at the location of the existing industrial site, which is currently in Karawang Regency. Therefore, this research was conducted to determine the condition of existing industrial land in flood-prone areas and to find predictions of economic losses that will be obtained in the event of a flood disaster on existing industrial land today. The research used secondary data in shapefiles (.shp) maps of Karawang Regency, planning documents, and related journals. Then, the analysis method that will be carried out is mapping disaster-prone areas in industrial estates and predicting economic losses due to flood disasters which will be carried out with a Geographic Information System (GIS). Based on the results of the analysis, it was found that 34.69% of the existing industrial land is located in flood-prone areas, which are predicted to impact the economic losses of IDR 65,049,705,681,272,-. That shows a need for a flood mitigation plan and the suitability of proper allocation of industrial estates to reduce the possibility of economic losses to be borne by the government.
根据国家灾害管理局的数据，从2020年到2022年，灾害总数有所增加，从最初的1296次灾害增加到5402次灾害，灾害事件百分比最高的是洪水灾害，西爪哇和DKI雅加达地区的频率最高(BNPB, 2022)。西爪哇地区频繁发生的洪水肯定会增加相当高的经济损失。另一方面，西爪哇省也贡献了全国第三大GDP。对西爪哇gdp贡献最大的部门是加工业部门(BPS, 2017)。卡拉旺摄政区是西爪哇工业发展的目的地地区之一。在卡拉旺县，工业区发展相当迅速，集中在卡拉旺县的南部(Telukjambe Barat, Telukjambe Timur, Ciampel, Pangkalan, Klari和Cikampek地区)。然而，根据ITB气候变化中心(2022)的研究，该地区有几个点的洪水危险程度相对较高。如果灾难发生在工业区，这可能会带来相当大的损失，因此需要对目前位于卡拉旺摄政的现有工业区进行洪水造成的损失分析。因此，本研究旨在确定洪涝易发地区现有工业用地的状况，并对现有工业用地在今天发生洪涝灾害时的经济损失进行预测。该研究使用了卡拉旺摄政的shapefiles (.shp)地图、规划文件和相关期刊中的辅助数据。其次，将采用的分析方法是利用地理信息系统(GIS)对工业园区的易灾区进行测绘，并预测洪水灾害造成的经济损失。根据分析结果发现，34.69%的现有工业用地位于洪水易发地区，预计影响的经济损失为65,049,705,681,272，-。这表明有必要制定一项防洪计划，并适当分配工业地产，以减少政府承担经济损失的可能性。
