Abstract

Tsunami is one of the catastrophic events that threatened coastal areas in Morotai Island Regency. This is partly because the location of the regency is among several active faults. Therefore, the study aims to analyze the tsunami inundation area and determine a tsunami evacuation route in Daruba Pantai Village, South Morotai District. This study begins with the preparation of a digital elevation model and is compiled with other related maps to produce the tsunami inundation area at the study site. The study results show that a tsunami can hit 176.65 ha, with the disastrous and dangerous category being 5.02% and 0.66%. Meanwhile, specifically for the Daruba Pantai Village area with an area of 60.59 ha, the disastrous and dangerous categories are 10.72% and 1.30%, and the safe category is 36.61% and secure 23.07%. Furthermore, the preparation of the evacuation route is based on the scenario that residents from each zone of both the Neighborhood Unit (RT) and Community Unit (RW) are directed to follow the evacuation path to move towards the temporary shelter point and towards the safety zone.

Abstract

Bunguran Besar Island in the Natuna Islands, Riau Islands Province, is dominated by a lowland topography with a sloping to steep morphological condition. In general, the plains on the island of Bunguran Besar have a plains topography with altitudes ranging from 5- 30 meters above sea level, and the highest altitude is on Mount Ranai, 920 meters above sea level. This condition causes environmental problems, especially on the plains that form basins with geodes that affect the condition of easily polluted groundwater resources influenced by the presence of shallow and close to the surface groundwater (aquifer). The condition of the aquifer, which is shallow and relatively close to the surface, has the potential for groundwater contamination by polluting sources. This study aims to determine the potential spatial groundwater pollution using the SINTACS method hydrogeological approach based on this background. The SINTACS method is a vulnerability approach by assigning a value and weight to each parameter or triggering the vulnerability. The primary data used for the vulnerability assessment were phreatic groundwater depth, soil texture, and slope. Meanwhile, the parameters of the infiltration conditions, the aeration conditions of the rocks, the compiler of lithology, and the hydraulic conductivity (K) or the passing of water in the rock were obtained from the secondary data approach. The scenario of groundwater pollution vulnerability uses the normal scenario impact approach. It is known that the condition of low vulnerability is 28% or an area of 486 km2, medium vulnerability is 20% or an area of 343.8 km2, high vulnerability is 0.04% or an area of 0.7 km2, and very high vulnerability is 52% or an area of 898.7 km2. In general, the condition of vulnerability in Bunguran Besar Island is very high.

Abstract

Kampung Dalam Bugis is an area in Pontianak City located in the Kapuas River and the Landak River branch. This area is a kampung and settlement that marked the establishment of Pontianak City. Kampung Dalam Bugis Village is located on the bank of a river, impacting flood disaster vulnerability. Therefore, it is necessary to study the correlation between the physical characteristics of the house and the level of socio-economic vulnerability. This study aims to analyze the correlation between the physical characteristics of the houses and the level of socio-economic vulnerability at the riverbanks. The analysis used to assess socio-economic vulnerability is scoring from data collected from interviews and filling out questionnaires. The study used to determine the relationship between the house's physical characteristics to indicators of socio-economic vulnerability is chi-square. The assessment of the community's socio-economic vulnerability on the banks of the Kapuas River consists mostly of high vulnerability classes. Chi-square analysis shows that indicators of socio-economic vulnerability such as the head of the family's educational level have a relationship to the house's characteristics, such as the type of house and the area of the house. This initial research still needs to be developed, such as using logistic regression analysis. There is more vital evidence that the information can be used as a basis for determining or at least as a validator for indicators of socio-economic vulnerability. Physical information of the house is easier to find data through observation and even image interpretation.

Abstract

Peri-urban provides complementary urban ecosystem services when green areas in cities are decreasing due to densification. However, land cover change in the area from natural landscapes to agriculture and settlements affects the ecosystem's capacity to provide services. This study aims to identify landscape transformation using a model and analyze its effects on cultural ecosystem services at Kawah Putih (White Crater) nature-based tourism destination area in the peri-urban in South Bandung, Indonesia. This study also analyzes how cultural ecosystem services and the increasing demand for new settlements in the area have influenced tourist visitation. Landscape change in the area (1989-2019) was identified from mapsdeveloped from Landsat imagery, using the Land Change Modeler (LCM) module in Terrset. A spatial assessment of offered cultural ecosystem services was then conducted using three indicators based on the land cover change near Kawah Putih. It is found that the composition of developed areas in the district has increased from 6.09% to 10.79% in 30 years. The quality of cultural ecosystem service has decreased, which is arguably influenced by the landscape alteration in the area. However, there was an increasing trend in the number of tourists (2016-2019) despite the deterioration of landscape quality. It is argued that the result is influenced by the visitors' perception of the landscape in the case study area. The rapid land cover change in the area was affected by the nearby city's growth, in which the tourism industry is one of the elements of such transformation.

Abstract

Fiscal decentralization is one of the government’s strategies to improve people’s welfare. The fiscal decentralization policy instrument that can directly affect the quality of local government spending is The Specific Allocation Fund (DAK). The DAK management in the financial aspect has a few problems, nonoptimal regional government performance and mismatched allocation and government needs. Proposal based The Specific Allocation Fund (DAK) hopefully could adjust the development priorities determined by regional conditions, government needs, and undeveloped villages with high-level poverty. Pandeglang and Lebak Regency are the region with the highest poverty level in Banten Province. This study aims to analyze the DAK effect of each sector on poverty in Pandeglang and Lebak Regency. The analysis used Geographical Weighted Regression (GWR) with DAK data for each field in 2018 and poverty data in 2019. The result showed that DAK variables in education, health, and agriculture tended not to reduce poverty rates. The DAK variable in the housing and settlement sector, the marine and fisheries sector, the tourism sector, and the market sector tended to reduce poverty. At the same time, the DAK variable in Road, sanitation, and village funds tended to reduce poverty levels in most districts. Based on the study, the poverty alleviation program in each district is adjusted to each of the DAK sectors that are influential. However, the result indicated that the adjustment of DAK sectors influenced the poverty alleviation program in every district in Pandeglang and Lebak Regency.

Abstract

Beach debris is an increasingly important issue to study considering its negative impact on the terrestrial and marine environment. This research aims to examine the distribution of beach debris in Timor Island as a basis for managing and overcoming waste pollution. The research was conducted in August 2020 on six government-managed tourism beaches consisting of one city (Kupang) and five regencies (Malaka, Timor Tengah Selatan, Kupang, Timor Tengah Utara, and Belu). At each location, a transect of 100 meters was made parallel to the shoreline with a transect width of 10 m perpendicular to the shoreline measured from the back of the beach. All trash in the transect was taken, then cleaned from the sand, then put in plastic bags that have been labeled. The wet litter was sun-dried before being counted. All waste was then sorted, then counted in the amount of item, weight, and length. The results showed that the entire beach had been exposed to unmanaged waste. Plastic waste dominates the entire site with a composition of numbers of items between 63 - 95% (average 80 ± 12%) and length between 60 - 93% (average 75 ± 13%). The composition of the weight of plastic waste is between 20 - 72% (average 45 ± 21%), where the weight of plastic waste does not dominate at Motadikin Beach. The dynamics of ocean currents in the eastern monsoon are thought to have played a role in causing lower debris quantification at the Motadikin Beach (Malaka Regency) and Oetune Beach (Timor Tengah Selatan Regency) than to the other four beaches located in the north of Timor Island. The source of beach debris comes from recreational activities, fishing and anchoring activities, and anthropogenic waste carried away from the sea.

Abstract

Covid-19 is a disease that attacks the respiratory tract that began to be identified in Wuhan, China. WHO then announced the condition as a pandemic that quickly spread throughout the world. The rapid spread of the Coronavirus Pandemic (COVID-19) also occurred in West Kalimantan, Indonesia. In a spatial-temporal perspective, the spread of infectious diseases can be happened by the interconnectivity or interaction between areas, populations, and transportation facilities that facilitate community mobility. This research aims to describe the interactions between regions in West Kalimantan and the relation to the spread of the Covid-19 pandemic. The method used centrality measurement and cluster analysis, where the results of these calculations are then described in line with the distribution of the Covid-19 case in West Kalimantan. From the justification, areas with high centrality in the network configuration tend to have the most confirmed cases compared to other areas. The character of these areas tends to be the main entrance (air/port), the provincial capital, and the hub area in West Kalimantan, which is also included as the same cluster. Another interesting finding is that areas with low centrality, and included in the same cluster, have several people under surveillance which is quite large compared to the previous cluster. These areas tend to have a dense population and are directly related to the Provincial Capital and neighboring countries (border).
