Local Wisdom of the Tradition of Pantauan Bunting in the Besemah Tribe in Lahat Regency
Full text linkIndonesia is a multi-cultural country characterised by hereditary traditions passed down by ancestors. Strands of this traditional culture are often specific to particular communities, for example the Pantuan Bunting tradition expressed and passed down in the customs of the Besemah community of Lahat Regency, South Sumatra. The purpose of this study is to analyze the social construction of the process of the formation of Pantauan Bunting tradition, the distribution of Pantauan Bunting tradition in different regions, and the existence of Pantauan Bunting tradition in Besemah Tribe community in Lahat Regency. The method used in this study was qualitative with ethnographic, historiographic, and spatial approaches. This research was conducted in three different locations, namely in Kota Agung Village, Penang Village, and Selawi Village where the research subjects consisted of traditional leaders, religious leaders, community leaders, and the Besemah community. The results of this study showed that (1) Pantauan Bunting tradition is constructed by the Besemah community since the time of its earliest ancestors and this process of transmission still continues. This tradition is characterised by a public invitation to prospective brides to come to their prospective bridegrooms’ homes. (2) Pantauan Bunting Tradition has spread to various areas in Lahat Regency, such as Kota Agung Village, Pulau Pinang Village, and Selawi Village. (3) in the modern era, the existence of Pantauan Bunting tradition is maintained by the Besemah community, and we can still find it in various areas in Lahat Regency. The Pantauan Bunting tradition, which has been practised in various parts of Lahat Regency since ancient times and is firmly ingrained in the Besemah community, highlights the community's resiliency and commitment to the preservation of its cultural legacy
Vulnerability Analysis of School Buildings to Tsunami in the Cilacap Coastal Area
Full text linkCilacap is one of several areas that experienced significant damage due to the Pangandaran tsunami in 2007. Currently, tsunamis are one of the most serious threats to coastal areas as they can cause devastation to the function of coastal areas. The physical environment can extensively affect the probability of damage caused by tsunamis. In addition, it is critical to maintain building stability as a substantial component in the integrated management efforts of coastal areas. The aim of this research is to assess the physical susceptibility and the vulnerability of school buildings to tsunami, particularly senior high school buildings (known as SMA/MA) located in the coastal area of the Cilacap region. This research is essential for the continuity of learning and teaching activities in the coastal area. Therefore, mapping the physical environment and school buildings in the coastal area of the Cilacap region is necessary. In this study, the physical approach method and Papathoma Vulnerability Tsunami Assessment (PVTA) model were optimally applied to assess coastal vulnerabilities to tsunami. Ultimately, the results were further evaluated by using cross-tabulation. The results confirm that specific coastal areas were categorised as having “moderate to high” susceptibility. Simultaneously, owing to the field survey, we determined that school buildings at this location were made of simple reinforced concrete materials. Notwithstanding that the vulnerability of the school buildings were low, the conditions were deemed to be reasonably harmful given that the schools were located in a “moderate to high” susceptibility. The results of this study have implications for the level of potential physical susceptibility of the coastal areas and the vulnerability of school buildings to tsunamis in the Cilacap region
Leveraging Geospatial Technology for Enhanced Utility Management: A Case Study in Electrical Distribution Power Systems
Full text linkOver the years, electricity has developed into a crucial commodity for any nation. The need to evaluate the rate of electricity consumption in regard to utility management and the spatial distribution of major devices to facilitate appropriate planning within the estate is the motivation for this research. This study used geospatial technology to evaluate the electricity distribution to support planning and management in Omole Estate (Phase One) and environs within the city of Lagos, Nigeria. The focus was on determining the land use in study area, geolocations of the transformers, along with the cost of energy consumed per household. Spatial data for the research area was collected through a Hand-held GPS. Google Earth images were downloaded to supplement the data, and a comprehensive analysis of administered and recovered questionnaires was conducted to enrich the dataset. ArcGIS 10.6.1 software was employed to create the database and depict the area, whilst modifying all of the details required within. The result confirms that 72% of the respondents use electricity for domestic use, 18% for commercial use while 10% utilise it for domestic and commercial use. A significant portion of homes (33%) still use outdated postpaid meters and 35% of respondents do not know how much power they use at home each month or the cost per unit of that electricity. Regarding the respondents, 67% have a prepaid card/electrical meter installed (per kilowatt). Concerning cost, 10% of the respondents spends between N1000-N5000 for their monthly electricity consumption, 27% of the respondents between N5,000 and N10,000, 38% between N10,000 and N17,000, 24% between N17,000 and N25,000 and 2% above N25,000 per month on electricity. These findings will assist effective power distribution within the estate and provide guidance on charge rates for commercial power users which is approximately 28% overall
The Study of Food Security in the Special Region of Yogyakarta, Indonesia
Full text linkFood security is a burden to realize sustainable development in achieving the zerohunger goal. This study aimed to examine the distribution of food security levels and the factors that influence the level of food security in the Special Region of Yogyakarta. Quantitative analysis was carried out in this study based on secondary data. The method of determining food security was carried out by applying the concept of the Food Security and Vulnerability Atlas (FSVA) which consists of three food pillars, namely food availability, access, and utilization. The results proved that Gunungkidul Regency was the area with the highest score for food availability, while the lowest were Bantul and Sleman. On the pillars of food access and food utilization, the highest was in Sleman, while the lowest was in Gunungkidul. The value of food security from the highest were the City of Yogyakarta (84.47), Sleman Regency (82.37), Bantul (79, 51), Gunungkidul (79.31), and Kulon Progo (79.03). All areas in DIY are included in very good food security. Food security policies need to be directed at handling food-poor households in villages through increasing knowledge about nutrition. Meanwhile in urban areas, it can be done through expanding job opportunities and community empowerment
Spatial Analysis of Mangrove Distribution Using Landsat 8 Oli in Badung Regency and Denpasar City, Bali Province, Indonesia
Full text linkBali is an island situated among the Indonesian archipelago with huge potential to host mangrove forests. Using remote sensing technology advances, satellite images, such as Landsat images, might be employed to analyse mangrove forest distribution and density. This paper presents an analysis of mangrove distribution in Badung Regency and Denpasar City, Bali, as a basis for the management and conservation of mangrove ecosystems. This study used Landsat 8 OLI images and a vegetation index to analyse the mangrove forest distribution and density in this area. It started by identifying mangrove forests using the RGB 564 band and continued to distinguish between mangrove and non-mangrove objects using unsupervised classification, before analysing mangrove density using the NDVI formula. The results show that the mangrove forest area in 2020 was 1,269.20 ha, with an accuracy rate of 83%. Mangroves were found on the deepest or most curved coastline of the Benoa Bay area, on enclosed waters. This distribution follows the river network in the lower reach, which has thick deposits and is uninfluenced by large currents and waves. Based on the vegetation index analysis results, the mangrove forest area observed mainly had a moderate density, with a total area of 510.85 ha (40%), followed by high density (413.15 ha/ 33%) and low density (340.51 ha/ 27%)
Coastal Vulnerability Study on Potential Impact of Tsunami and Community Resilience in Pacitan Bay East Java
Full text linkCollisions or harsh shifting of earth plates accompanied by an earthquake in the ocean would pose a potential tsunami. The coastal area in Pacitan Bay East Java faces directly to the Indian Ocean and is prone to tsunami disasters. This study aims to determine the vulnerability level of the area and the resilience of coastal communities against tsunamis. The geographic Information System (GIS) method was used in this study. This study applied weighted overlay calculation with four components: elevation, slope, and distance from the beach and the river to measure the vulnerability level. Moreover, Coastal Community Resilience (CCR) method was applied to measure the predictive response of the communities. The results indicated that most of the area in Pacitan Bay (79,70%) was categorised into high to very high vulnerable against tsunamis. The CCR results showed the low index structure design and post-disaster recovery elements
Simulated Mitigation of Tsunami Disasters in the Coastal Area of Purworejo Regency, Central Java, Indonesia
Full text linkThe coastal area of Purworejo Regency has the potential to be hit by a mega-tsunami disaster because it includes the southern coast of Java Island which is faced with seismic gaps that may produce large earthquakes in the future. This study aims to simulate tsunami disaster mitigation in the coastal area of Purworejo Regency in an effort to raise awareness and increase the community capacity for dealing with potential tsunamis so that the level of loss can be minimized. The tsunami risk analysis is based on the Disaster Crunch model, which is a combination of vulnerability analysis based on the weighted overlay quantitative method and tsunami hazard analysis based on tsunami inundation reduction modeling and cost distance analysis. The planning of the tsunami evacuation route is based on the network analysis method. The tsunami-risk area with a run-up scenario of three meters in the coastal area of Purworejo Regency 126,29 square kilometers or about 72,52% of the total coastal area. There are five tsunami evacuation plan points, with five main tsunami evacuation routes that lead directly to each of these points
Predisposition Factor of Safety of Landslide Dams from Typhoon Talas, Kii Peninsula, Japan
Full text linkLandslide dams are less frequent than other landslides, and their very existence is often very-much short-lived, because the temporary dam tends to collapse rapidly. Because of the resulting lack of evidences, there has been less research done on this topic, although the potential catastrophe they can be at the origin of needs assessment. For this purpose, the present contribution aims at differentiating landslides that trigger dams against those that do not inside a group of valleys of the Kii peninsula in Japan, where landslides occurred af-ter the typhoon Talas in 2011. Using topographic map before the event and LiDAR data in its aftermath, the authors have calculated the factor of safety (FS) of different landslides in the same valleys, comparing the da-ta of landslides that created dams against those that did not. The results show that landslides that triggered dams seemed to have a higher FS than those that did not. The authors suggest that it is because larger land-slides are needed and thus appear more stable, but also because at the location where the slopes are stable, the riverbed can incise further instead of growing horizontally, and thus the sediments damming the channel have more chances to block it (as it is narrow) and stop the river from flowing
A Green Economy Approach to Solid Waste Management in Minna, Nigeria
No full textThis study is based on solid waste recycling activities in Minna, Nigeria. This study examines the potential for waste recycling to provide livelihood opportunities in Nigeria. The study identified two recycling centres in Minna and collected data through direct observation, measurements, questionnaire administration, and interviews. The collected data was analyzed using statistical packages for social sciences and livelihood approach to demonstrate the green value of recycling, identify impediments to green growth, and map the recycling cluster. The result shows that the recycling cluster occupies an area of 0.64 hectares that accommodates 141 recycling outlets, with about 40% of the outlets occupying below the standard shop size of 7.2m2. The recycling outlets use 18 types of recovered materials to reproduce 27 varieties of products. Each recycling outlet engages about 3.4 persons and offers training to an average of 6 persons each. The study highlights the importance and potential of informal solid waste recycling as a sub-sector that fulfils social, economic, and environmental benefits associated with sustainable development. However, the lack of commitment by governments to waste recycling undermines the contribution of the recycling business. Moving towards the zero-waste policy can save public funds that can be invested in the waste disposal and reduce the threat to public health from solid waste. Furthermore, safety measures should be ensured among the scavengers and the recyclers, and the physical environment of the recycling cluster should be upgraded to take care of poor accessibility and the use of makeshift structures by most of the recycling units. Governments should focus on policies that encourage waste sorting, collection, sales, and solid waste processing at all scales. We underscore the need for creative and reliable government support to achieve green growth and development in the solid waste recycling sector
Sugarcane Growing and the Livehoods of Small-Scale Farmers in Jinja District, Uganda
Full text linkThis study focused on establishing the relationship between sugarcane growing and the livelihood of small-scale farmers in Jinja District. It was guided by three objectives namely: to characterize individual farmers and their farms, establish benefits from sugarcane farming to the farmer’s livelihoods and find out the effect of sugarcane growing on household food security in the area. The study adopted descriptive research design. The target population of this study were sugarcane growing households’ heads and Village Chairpersons of sugarcane out-growers association. The study employed the purposive and simple random sampling techniques. A sample size of 42 respondents from a population of 362 small-scale farmers. The methods of data collection included; use of questionnaires, interviewing, focus group discussions and observation. The study generated both qualitative and quantitative data. The data collected was analysed by computing percentages while qualitative data was analysed by coding and establishing common themes. The study findings revealed that although women are fully involved in sugarcane growing, ownership of farms is dominated by men. The dominant age group among the sugarcane farmers is between 30 to 60 years, with mainly primary education graduates. The average farm size was 3 acres and the larges part of the farm land is devoted to sugarcane growing. There are some positive benefits from sugar growing, though many challenges have been identified. Most smallholder farmers are experiencing food insecurity. Based on the findings of the study it was recommended that there was need to encourage people owning land less than five acres to practice mixed farming, use scientific methods of farming such as intercropping, crop rotation, use fertilizers to facilitate better yields and crop diversification to improve both on their earnings and food security
