Abstract

The increasing need for land has resulted in a higher rate of land conversion and urbanization, leading to a rise in urban density and the occurrence of an Urban Heat Island (UHI) effect. The application of remote sensing and GIS can serve as a substitute for data collection in monitoring the UHI phenomena. This work utilizes Landsat 8 OLI satellite image data, namely band 10, to analyze Land Surface Temperature (LST). Bands 5 and 4 are employed to assess the distribution of Normalized Difference Vegetation Index (NDVI) in Bekasi Regency during the years 2014 and 2020. The relationship between NDVI and LST is highly correlated as they can effectively forecast the influence of areas with sparse vegetation on temperature. The guided classification approach, employing the maximum likelihood algorithm and kappa validation, is utilized to evaluate alterations in land use. The kappa accuracy test yielded a score of 0.90% for 2014 and 0.99% for 2020. The research conducted between 2014 and 2020 revealed changes in land distribution. Specifically, the built-up land area increased by 99.92 Km2, empty land expanded by 280.82 Km2, bodies of water covered an additional 46.13 Km2, and vegetation expanded by 293.91 Km^2. According to the UHI research, it is evident that there has been a rise in surface temperature in Bekasi Regency from 2014 to 2020. In 2014, the minimum temperature reached 30 °C, and the maximum temperature reached 51 °C. In 2020, the minimum temperature was recorded at 34 °C, while the maximum temperature reached 52 °C.

Abstract

Coastal areas are experiencing a high population density that is increasing the vulnerability of community to coastal hazards. Therefore, this study aimed to comprehensively evaluate the preparation level of community to confront coastal hazards. Disaster preparedness was recognized to play an essential role in reducing potential losses caused by flood. However, limited studies assessed community preparedness on small islands using face-to-face interviews with community. A household survey was also conducted on community living on Pusong Island. The results showed that community preparedness was still low (38.34% of 100). Even though tidal flood events were experienced, community were not forced to take preparedness actions and move from Pusong Island. The low level was due to socialization activities and community capacity building related to coastal hazards rarely performed by the government. This study also suggested the importance of increasing the preparedness on remote islands through integrated coastal area management.

Abstract

Blended learning needs supporting components to be able to achieve learning objectives. The use of Blended Disaster Learning Multimedia (BDLM) is used as teaching material to support the blended learning process. The purpose of this study was to determine the effect of using BDLM on knowledge of disaster preparedness. We used a quasi-experimental design using a pretest posttest non-equivalent control group design. Data were analyzed using ANCOVA. Research participants were prospective geography teachers who are participating in the lecture program in the 2021/2022 academic year. To assess the knowledge of disaster preparedness using an essay test that is adapted to disaster preparedness indicators. The results show that BDLM integrated blended learning has an effect on knowledge of disaster preparedness. The experimental group appears to have superior knowledge of disaster preparedness with superiority in all indicators of knowledge of disaster preparedness. There is no significant effect between gender differences, because the treatment does not discriminate between gender. The interaction between BDLM learning and gender has a significant effect due to BDLM is a medium that focuses on learning activities not on the treatment of gender differences. The perceived impact is that using BDLM can increase disaster preparedness knowledge. Therefore it is necessary to apply it to prospective geography teachers more broadly.

Abstract

Bogor is one of the cities in Indonesia with a dense population and is experiencing population growth every year. Like other city problems, waste is also a problem in Bogor City. Waste generation in cities like Bogor City has been continued to increase since 2005. Even though the Bogor City Government has socialized with changes in waste management with a new paradigm, those living in residential areas are still using the old paradigm principle which is collect-transport-throw (end of a pipe). Therefore, a study was conducted to determine the waste generated and the perception and role of community participation in managing waste, especially household waste in residential areas. In this study, data collection was carried out in one of the housing areas in Bogor City, namely the Pakuan Regency. The collection of daily waste data to measure waste generation and composition is carried out based on the Indonesian National Standard 19-3964-1994 method. This data analysis technique uses a qualitative descriptive analysis with respondents differentiated on the basis of type of house and the number of occupants. This research produces data on waste generation for small, medium, and large house types 286,12 kg/houses/year, 366,57 tons/houses/year, and 523,67 kg/houses//year respectively. The result showed that the total of household waste, the level of participation and the household’s willingness to pay for TPS 3R plan made it possible to implement the TPS 3R program in this residential. Operational cost for TPS 3R can be covered from the retribution annual revenue.

Abstract

Developing new and renewable energy (NRE) is a sustainable solution to the current complexity associated with population growth and environmental problems. Some developed countries have recognized renewable energy development as a substitute for non-renewable energy such as coal, petroleum, and natural gas. Therefore, this study employed the geospatial approach scheme to identify the NRE potential in the Cipunegara watershed. This was achieved using regional research with a spatial approach and considering five locations in the upstream area of the Cipunegara watershed. Data were collected through observation, consultation with experts, and map interpretation, and analyzed using descriptive statistics. The results showed that only location 2 had a significant potential to be used in building a dam to generate electrical energy. This study was based on several aspects such as hydrology, morphology, topography, meteorology, erosion, geology, and land use. The results were derived from empirical data and geospatial modeling, and expected to serve as a significant reference for the central government in developing EBT as the tangible manifestation of the Sustainable Development Goals 2030 program and the implementation of the national research master plan 2017-2045.

Abstract

The Citarum River is facing pollution and damage due to domestic and industrial activities. The provincial and national governments have implemented several programs to address the Citarum issue. One key aspect of rehabilitating the Citarum River basin is the increase in environmental awareness among the community. This research aims to examine the influence of the Citarum Harum Program on the formation of Eco-literacy among the communities in Upper Citarum. A survey was conducted with 393 respondents who reside along the banks of the Upper Citarum River, distributed across the 8 sectors of the Citarum Harum Program. The research instruments used include structured questionnaires, documentary studies, and interview guidelines. Data analysis was performed using the Structural Equation Modeling (SEM) technique with SmartPLS software version 3.2.9. The results of the study indicate that Eco-literacy (ECO) has a positive correlation with the handling of existing problems (HP) with a t-value of 1.136. Eco-literacy (ECO) has a negative correlation with the physical, social, and environmental characteristics (CH) with a t-value of -0.486, as well as with the occurrence of problems with a t-value of -0.237. This suggests that the formation of eco-literacy among the communities in Upper Citarum is highly dependent on the efforts undertaken by the task force. However, there is currently no connectivity between the knowledge and attitudes of the community towards actions in the restoration of river pollution and damage.

Abstract

The complexities and consequences of violent crimes require a robust and effective approach to achieve a sustainable reduction of violence in our society. This paper, therefore, presents an avenue to provide the geo-quantitative analysis of violent occurrences in Kaduna State of Nigeria to determine the pragmatic interventionist strategies for managing violent crime incidence among the people of the study area. Geo-quantitative analysis entails transforming numerical data about criminal activities into a map of proportional circles to depict the distribution pattern of criminal activities and using scree plots and factor loading to show higher-order intervention measures for managing violent crimes. Five Local Government Areas (LGAs) with relatively high levels of violent incidence were purposively selected while snowball sampling method was used to administer questionnaires to 384 respondents. From the findings, the spatial distribution of violent crimes revealed that Birni-Gwari and Kachia LGAs accounted for the highest incidence of kidnapping and village raids respectively while Kajuru LGA is known for the highest cases of cattle rustling and armed robbery. The critical interventions in managing violent crimes are reconciliation efforts to restore order and normalcy, negotiation between aggrieved parties, and adoption of a traditional conflict resolution system with a rotated factor matrix of 0.828, 0.581, and 0.544 respectively. Furthermore, the strongest positive correlation exists between good government policies and equity with fairness in representation and establishment of developmental projects (r = 0.524, and p Ë‚ 0.001). Therefore, the study recommended establishing conflict mediation centers across the communities. Similarly, it is essential to have a good governance system that will give people their fair share of national resources and adequate policing of communities that could guarantee the reduction of violent incidents to the barest minimum.

Abstract

Shallow coastal bathymetric data has an important role in various applications, especially in maritime and coastal management fields. Various survey techniques to produce such data have been carried out by several researchers, one technique that is cheap, covers the wide area, flexible, and produces high-resolution bathymetric data is UAV-photogrammetry. However, this technique is affected by refraction effects that cause the estimated depth of underwater objects to be shallower than fact, thus reducing the accuracy of the bathymetric model. Therefore, the objective of this study is to present a simple refraction correction method based on the Least-Square method. To test the reliability of the method, the accuracy of the model is compared with two other methods (without correction and using a correction factor = 1.34). In addition, the effectiveness of the method was also tested through its application in various survey conditions. Overall, the proposed method outperforms the two existing methods. It is also very effective in reducing the error value during high tide conditions by up to 70%. The height of the UAV does not significantly affect the accuracy of the correction model, so in this case it is recommended to use an altitude of 100 m for survey efficiency.
