Abstract

The construction of a new airport in tsunami disaster prone area in Kulon Progo Regency has been impacting in land use and land value. The changes in land use will impact on changing tsunami hazard model. This research aims to analyze the impact of a new airport on physical changes and land value changes in Temon District with geographic information system. The research begins with inventory of spatial data from various agencies. Multi-temporal image interpretation is resulted in 2015 and 2020 land use maps. Physical changes and tsunami models analysis were carried out using spatial analysis in ArcGIS. The making land value change maps using 2015 and 2021 land value zone maps. The analysis effect of new airports and tsunami hazard using multiple linear regression. Data validation was carried out by sampling techniques and field surveys. The results of spatial analysis is physical growth from 2015-2020 covering an area 418,019 m² and loss of a built area 149,261 m². The changes in the tsunami model from 2015-2020 increased by 118,740 m². The changes in land value from 2015-2021 is increasing the average value of Rp. 1,317,088/ meter² or 652%. The results of multiple linear regression analysis and community interviews concluded that the existence of an airport is very influential on increasing land value compared to the effect of tsunami vulnerability.

Abstract

According to the National Disaster Management Agency, in 2021 there were 5,402 incidents recorded, one of them being drought disasters. During the drought, the availability of clean water was minimal, so clean water assistance came from other areas. The problem that is often encountered in the field is delays in water distribution assistance due to sudden information and the location of the aid is in areas that are difficult to reach. This research developed a water tank technology equipped with a sensor to provide information about water availability, the location of the tank placement to speed up information on dropping water in drought areas. This technology uses the NodeMCU ESP8266 module which functions as a microcontroller, to provide sensor-based information that detects the quantity and quality of water as well as the location of the tank. This system is based on the Internet of Things (IoT) and Blynk Android which makes it easier for people to get information in real time. The water availability indicator is presented in a three-color graphical display, namely green is a safe sign (sufficient water), yellow is a warning sign (water is reduced), and red is a sign that water availability is running low and it is necessary to drop clean water. Other information presented is water quality parameters such as pH, TDS, turbidity, and temperature as well as the location of the tank. This technology supports the achievement of SDGs, namely goals number 6 (clean water and proper sanitation) and 11 (sustainable cities and settlements).

Abstract

The purpose of this study was to identify the influence of physical and social vulnerability factors due to the eruption of Mount Merapi in Yogyakarta. Furthermore, this study identifies the significance of physical and social vulnerability to the achievement of the SDGs in Yogyakarta. The achievement of SDGs number 11 is supported by indicators of the percentage of the number of dead or missing victims to the total number of disaster events, disaster risk index, regional resilience index, number of resilient villages/kelurahan that have been formed, integrated early warning system, and availability of contingency plans. The achievement of SDGs number 13 is further explained using a simple indicator, namely greenhouse gas emissions. In this case, the research contribution is expected to add an indicator explaining the achievement of SDGs number 13 in addition to climate change. This study uses IRBI (Indonesian Disaster Risk Index) data to indicate the achievement of disaster risk reduction in the research area. The achievement of the SDGs, which has increased every year, certainly has positive implications for handling vulnerable groups. The location of this research study is the District of Turi. Turi sub-district is important to be studied considering the current conditions and potential future exposure to the eruption of Mount Merapi. This study utilizes the Analytical Hierarchy Process (AHP) technique to determine the weight of the indicators used in vulnerability modeling. The research data were tested using statistical analysis of data normality, probabilistic Poison, and the two-way ANOVA effect test. The results showed that there was no influence of the variables of physical vulnerability and social vulnerability on the existing SDGs. The conclusion of the research on the effect of physical and social vulnerability factors on the eruption of Mount Merapi Volcano shows that there is no influence of the value of physical and social vulnerability in Turi District on the achievement of SDGs in the form of the DIY Disaster Risk Index

Abstract

Every city keeps growing as a result of population growth and has an impact on space requirements. Same as Banda Aceh City which continues to grow, but its development has stopped due to the 2004 tsunami disaster. Residential areas tend towards the north or the coast, which is tsunami-prone zone. The purpose of this study is to describe the direction and built-up area development of Banda Aceh City after the tsunami from 2005-2011, 2011-2015, and 2015-2020. The data used in this study is spatial data such as maps and satellite images sourced from Banda Aceh planning and development agency. Data analysis uses spatial approach with the overlay method. Development of the built-up area of Banda Aceh city based on the period 2005-2011, 2011-2015, and 2015-2020 shows that the built-up area leads to the northern and southern parts of Banda Aceh City. Development of the northern part of the city, Districts of Jaya Baru, Meuraksa, Kuta Raja, Kuta Alam, and Syiah Kuala was a result of the rehabilitation and reconstruction efforts such as housing, roads, and facilities after tsunami and turned the ponds and vacant land into housing and service trading areas. The northern part of Banda Aceh City was tsunami hazard-prone zone. Meanwhile, development of the southern part of the city, districts of Banda Raya, Lueng Bata, and Ulee Kareng, was influenced by Mohamad Hasan and Ali Hasyimi street which triggered the development of residential areas, office areas, service trading areas, and public facilities. Southern part of the city was not directly affected by the tsunami disaster. In addition, built-up area development has spread to the Aceh Besar regency.

Abstract

The theme of cultural landscape function becomes very important along with the awareness to create a balance of ecological and social landscape functions in urban areas. Urban settlement strongly influences cultural function, both as a form of landscape and demographic characteristics. This paper aims to examine the existence of several important social values in urban settlement landscapes and the role of landscape features in influencing social values aspects of informal residents such as social cohesion, recreation, sense of place, spiritualism, cultivation, and business activities. The research method used is a mixed quantitative and qualitative method by using observations, questionnaires, and interviews for data collection based on a sociological approach with community members. Questionnaire data were collected for further analysis in which the Spearman coefficient was used to examine the relationship between social values and landscape features. The results revealed that residents in Airmata and Manutapen have different percentages of social values in terms of their landscape features, and it can also be seen that the values of social cohesion, sense of place, and local business present a stronger relationship to landscape functions. These results show the importance of social values in informal societies as a potential approach to achieving sustainable landscape management.

Abstract

Rawabogo Village is one of the tourist villages in Bandung Regency with insignificant development since its establishment. Community participation is important in the stages of development. However, measuring context in real time and accurately is generally difficult. Neuroscience can be used to control the validity and subjectivity of the questionnaire and interview methods used to examine neural responses to tourism conditions. Thus this study aims to identify the people of Rawabogo Village's interest in developing a tourism village based on neuroscience methods. The results of the data analysis show that the people of Rawabogo Village have a strong interest in developing a tourist village. The result is indicated by the entropy value obtained and the results of the questionnaire scoring. The neuroscience method in tourism village development acts as a method that supports, complements, and validates existing tourism village development concepts or methods such as Community Based Tourism (CBT).

Abstract

Currently, many people live in urban areas and more than 30% of them live in slums or squatter settlements. Urbanization is one of the most transformative trends occurring worldwide, especially in developing countries like Indonesia. At present, more than half of the total population in Indonesia lives in urban areas. The dominance of the urban population shows the urgency to make the urban environment inclusive, safe, resilient, and sustainable as it is intended to be realized through Goal No. 11 - SDGs 2030. Cities require large spaces and are a major source of wealth and centers of innovation, culture, and politics. The urban area has become the most important arena for people, including low-income communities that live in informal urban spaces that develop spontaneously. This article will share research experiences on the settlements of marginalized communities. With the help of several institutions, the communities are trying to improve the quality of their settlements to become inclusive, safe, resilient, and sustainable. The method used in this research is the descriptive-qualitative method exploring the potential and resources within urban kampong to improve the quality of urban poor settlements. With the discovery of informal urban space patterns and community efforts to improve the quality of their settlements, a sustainable development strategy can be developed to improve urban areas inhabited by low-income people.

Abstract

Cross-infection has the potential to occur in the Dental and Oral Hospital due to cross-transmission of pathogenic microbes through dental chair surfaces that are contaminated with microbes. This  study aims to compare the effectiveness of three types of disinfectant Septalcan, Terralin, and 70% alcohol on the inhibition of pathogenic microbes originating from the oral cavity of patients who contaminate the surface of dental chairs in aerosol and non-aerosol clinics. Sampling of microorganisms was carried out using the technique of wiping/swab the surface of dental chairs in aerosol and non-aerosol clinics before and after the disinfection process with three types of disinfectants. The decrease in the number of germs before and after the disinfectant process is used as a parameter for the effectiveness of the disinfectant. The results of the one-way ANOVA statistical test shows that there is no significant difference in the effectiveness of the three types of Septalcan, Terralin, and 70% alcohol in reducing the number of germs on the surface of dental chairs. The three types of disinfectants are able to minimize the risk of cross-infection due to pathogenic microbial contamination on the surface of the dental chair.
