Authors: Yunita R , Wibowo A , Supriatna  , Rais A F
Published: September 2022

Appropriate strategies on urban climate mitigation should be formulated by considering the physical morphology of the urban landscape. This study aimed to investigate, analyze, and promote possible strategies to mitigate Jakarta’s urban heat island (UHI) phenomena. Jakarta’s local climate zone (LCZ) was classified into 17 classes using Landsat 8 data and the random forest method. Land surface temperature (LST) characteristic in each LCZ class was analyzed from 2018, 2019 and 2020. The result revealed that most of the local climate zone in Jakarta is dominated by LCZ 6 (open low-rise) and LCZ 3 (compact low-rise), which is the typical residential area in Jakarta. However, the mean LST in 2018, 2019 and 2020 showed that LCZ 3 (compact low-rise) and LCZ 7 (lightweight low-rise) are the areas that were most likely causing high surface temperature with the highest UHI intensity. During the COVID-19 pandemic in 2020, LST in Jakarta decreased drastically in some parts of the area, especially in public facility such as airport. However, the LST value in low-rise areas (LCZ 3 and LCZ 7) remains higher than the other LCZ classes. Materials of the building and land cover play a significant role in raising the land surface temperature. Therefore, mitigation strategies for urban heat islands in Jakarta should be focused on such particular areas mentioned.

Authors: Alfatih M A , Rachmawati R
Published: September 2022

The number of positive cases of COVID-19 in the Special Region of Yogyakarta (DIY) is still increasing every single day. One of the measures which can be taken to reduce the number of positive cases of COVID-19 is to provide credible and valid information services regarding the disease. The information provider service is in the form of an interactive hotline so that people can ask for more detailed information related to COVID-19. The purpose of this study is to identify the provision of information about COVID-19 through the COVID-19 Hotline in DIY and analyze its trend of the utility. The research method used is qualitative with descriptive analysis techniques. There are two types of COVID-19 hotlines operating in DIY managed by the Regional Disaster Relief Agency (BPBD) and the Health Office of DIY. The results obtained from this study are the trend of the number of COVID-19 Hotline users in DIY is fluctuative according to the situation and conditions of the COVID-19 pandemic in DIY. The information submitted to the BPBD DIY COVID-19 Hotline is general information related to the way of handling COVID-19. Meanwhile, more detailed health information and mechanisms for handling COVID-19 can be obtained through the COVID-19 Hotline of the DIY Health Office. Through this research, it can be concluded that the COVID-19 Hotline in DIY can provide the information that the community needs. The most asked category of information was related to health services regarding COVID-19. The trend of the utility of the COVID-19 Hotline can be seen through the spread of incoming calls. The largest number of users is in the city of Yogyakarta. This is due to the highest positive cases of COVID-19 in DIY are in the city of Yogyakarta, so the need for information related to the development of COVID-19 also increases. The difference in the number of COVID-19 calls in DIY in each regency can be caused by the COVID-19 Hotline service at the city and district levels as well.

Published: September 2022

In early March, Indonesia had reported the first two cases of COVID-19 and this was the beginning for the spread of the COVID-19 outbreak in Indonesia. The need for health services is increasing along with the increasing number of COVID-19 cases in Indonesia. DKI Jakarta is the capital city of Indonesia and is a city with a dense population, causing the transmission of the COVID-19 to be faster than other areas. An assessment of the capacity of health facilities which includes infrastructure and resources is very important to determine the ability of health facilities to manage the rate of spread of COVID-19. This study aims to evaluate the capability of health facilities using the COVID-19 referral hospital readiness index in DKI Jakarta. The data used is the availability of human resources and infrastructure for COVID-19 referral hospitals. Analysis of Geographic Information Systems and Multi-criteria was used to map the readiness index of COVID-19 referral hospitals. The results show that there are no referral hospitals with a high readiness index. There are only 10 referral hospitals with a medium and 92 referral hospitals with a low readiness index. The lack of referral hospitals with a medium readiness index in areas of high vulnerability can have serious consequences in handling COVID-19 cases. Most of the referral hospitals have a low readiness index. However, referral hospitals are capable to reach almost all areas of DKI Jakarta in an emergency condition. It can be concluded that most of the referral hospitals do not have adequate facilities for handling COVID-19 patients.

Authors: Santosa H , Hadi M , Imarjoko Y
Published: September 2022

Environmental protection is a big issue of NPP technology. Approaches so far have not conducted adequate assessments for severe accidents. Efforts to correct this deficiency are carried out by utilizing the phenomenon of the Fukushima Daiichi NPP accident that has been documented. Relevant aspects were selected to be contributed to the NPP EIA thereby increasing coverage to severe accidents. Content analysis of accident reports and supporting information from international nuclear institutions as well as expert opinion was carried out. The analysis provides results in the form of eight aspects that are suitable to be contributed to the NPP EIA. The correlation between nuclear power generation capacity and environmental radioactive contamination from its accidents and recovery needs is a knowledge challenge that is still being faced. The idea of making the impact of a nuclear power plant accident easy to recover has the potential to be a direction for the development of knowledge and engineering.

Published: September 2022

Landslide is a geological disaster that is still an interesting topic to study its behavior and its management, especially for tropical climate regions such as Indonesia. One form of landslide countermeasures is the mapping of landslide susceptibility. The most commonly used landslide susceptibility mapping method is the GIS-based weighting and classification method. In the weighting method, each parameter and class has a definite weight as in the reference for making vulnerability maps that have been issued by BBSDLP (Center for Agricultural Land Resources) and PVMBG (Center for Volcanology and Geological Hazard Mitigation). However, the exact weight of each parameter sometimes does not match the real conditions in the field, so many researchers modify it. For this reason, this study tries to present an accuracy comparison of mapping the vulnerability of land motslide with the weighting method and the Analytical Hierarchy Process (AHP) method. The research location is in the Pringapus and East Ungaran areas, Semarang Regency. The results showed that the mapping of landslide susceptibility using the weighting method showed an accuracy of 77.58% while using the AHP method showed better accuracy of 84.48%.

River flood has become a severe disruption toward the community, and it can trigger loss of life, damage infrastructure and properties, suffer economic, social and cultural, and environmental degradation. Flood hazard analysis downstream of Comal Watershed in Pemalang Regency, Central Java, was designed to generate the flood hazard map to reduce the effects of flood disaster. The flood hazard was simulated for five, 10, 25, and 50 years using HEC-RAS and ArcGIS with HEC-GeoRAS. The data input was discharge, geometry, and roughness. The discharge was obtained from hydrology modelling by utilizing daily rainfall data for 22 years. The geometry data was composed of a topographic map and measured using an echo sounder, while the roughness was from land use along the flood plain. The accuracy and validation were conducted by matching the flood modelling result with the historical data from the Pemalang Disaster Management Agency and in-depth interview results with the community. The results showed the Comal River downstream flood hazard was feasible for disaster risk reduction purposes. The flood hazard levels were generated in five, 10, 25, and 50 years return periods dominated by high and very low levels. In every return period, the rising trend of the inundation width and the flood depth occurred for very high, high, and very low levels.
Mainstreaming sustainable use of suboptimal lands to support food security in Indonesia
Authors: Qurani I Z , Fawzi N I
Published: September 2022

The majority of land types in Indonesia consist of suboptimal lands. Their conditions are either too dry (i.e acidic dryland, arid land), or too wet (i.e swamps, peatland). This made the soil fertility low, highly acidic, and more costly to be managed. Despite the circumstances, suboptimal lands hold a significant contribution to support food security especially in the provinces where these land types share a large distribution. While the existing agricultural policies and practice tend to overlook the lands’ potential, this research attempted to offer a framework to mainstream the sustainable use of suboptimal lands and ways to embed them further into the nation’s development agenda. This paper adopted the Sustainable Land Management Mainstreaming Tool and used a qualitative descriptive approach to gather data and analysis based on literature study. It explored five key aspects that determine the viability of the mainstreaming effort: policies and regulations, incentives and financing mechanisms, land-use and territorial planning processes, and farmers development. Recommended policy options thus generated from each aspect and assessed using change space parameters that divided the result into high-priority, game-changing, and supplementary policies to mainstream the suboptimal land agriculture.

Published: September 2022

A disaster-prone area is an area that has a high level of vulnerability to potential threats to life, welfare, and residents’ assets when a disaster occurs. Land damage due to landslides has the potential to reduce the region’s ability to supply human resources, especially in the agricultural sector. This condition has an impact on decreasing the carrying capacity of agricultural land. This study aimed to analyze the distribution pattern and carrying capacity of agricultural land in the disaster-prone area of the Karangsambung-Karangbolong Geopark. Data sources used were secondary and primary data. The secondary data were obtained from the Central Bureau of Statistics of Kebumen Regency and the Regional Disaster Management Agency of Kebumen Regency. The primary data were obtained from observation and in-depth interviews. Data analysis was carried out in a quantitative descriptive manner. The carrying capacity of agricultural land was obtained using the Odum-Howard-Isaard agricultural land productivity approach with a classification based on Decent Living Needs (DLN). The results showed that the available land carrying capacity (LCC), especially rice fields, was lower than the farmers’ needs thus the LCC value was a deficit. In geopark areas that had low LCC and was indicated by low levels of agricultural production could not be able to carry out food self-sufficiency. The carrying capacity of agricultural land in disaster-prone areas can be increased through policies to prevent land conservation and intensify agricultural land processing.

Published: September 2022

Caota Sand Dunes Geopark was established in June 2020 and conserves a landscape of coastal sand dunes at the Taoyuan coastline. This is the first geopark in Taiwan to promote the value of coastal dunes, recognizing their ecological value and their protection function in the face of climate change. This geopark has been actively promoted and attracts many visitors owing to its unique and photogenic landscape. In the initiation phase of a geopark it is significant to get feedback on the planning and services, to evaluate the existing management strategies for future development. Therefore, this study will assess tourist perceptions through visitor comments from Google reviews, to explore how well the core values of the geopark are represented in visitors’ experiences. A qualitative methodology based on review analysis has been used to find themes and patterns. Many reviews point out that washed-up waste is still a huge issue at the Caota dunes and mention that the Geopark development has not been completed. However, there is consensus on the fact that Caota Dunes is a very promising site, and with more planning underway it can become a successful geopark. Future management strategies should address the issues that are pointed out in the reviews for the sustainable development of this scenery post the Covid-19 Pandemic.

Published: September 2022

Human-caused changes in land-use and land-cover (LULC) are most visible in metropolitan areas, when the majority of the land has been converted to urban land or built up. This study presents a modeling approach for simulating the spatiotemporal distribution of urban microclimate with the Weather Research and Forecasting (WRF) model using four urban parameterization schemes, namely a bulk, urban canopy model (UCM), building effect parameterization (BEP), and building energy model (BEM). The WRF model is set-up at 1 km spatial resolutions over the Jakarta Metropolitan Area to study the model’s sensitivity to the usage of alternative LULC datasets, the default MODIS and its modification 2017. The results show that the UCM and BEM schemes appear to be reliable in mapping urban weather conditions for all meteorological parameters examined. Given that the LULC categories in urban areas remained unchanged, changing the LULC in the model did not result in a large difference in error. The LULC dataset, on the other hand, can be used as information related to suburban areas that continue to grow in concurrently with urbanization. LULC updates can provide insight into how much temperature rise is occurring in urban areas and how it affects climate change.

Over the last ten years, the Bedog Sub-watershed area has continued to develop into an urban area. Along with these developments, land-use change processes occurred in the Bedog Sub-watershed area, especially the reduction in agricultural land, which was depressed by population growth. For this reason, the purpose of this study is to identify population pressure on agricultural land, identify the carrying capacity of agricultural land, and develop sustainable management strategies based on the carrying capacity of agricultural land in the Bedog Sub-watershed. The calculation method utilized was the measurement of population pressure on agricultural land and the carrying capacity of agricultural land, analyzed spatially with distribution maps. The sustainable management strategy was then formulated through the SWOT method. Overall, in the Bedog sub-watershed, the carrying capacity of agricultural land was low, while population pressure on agricultural land was high. Thus, sustainable management strategies in the Bedog Sub-watershed can be carried out by increasing land productivity, diversifying non-agricultural jobs, empowering farmers, optimizing land use, and innovating environmentally friendly agricultural technology.

Authors: Ni’mah Novi Maulida , Priyoga Iwan
Published: September 2022

In the realm of urban planning and design practice, understanding urban morphology can be the basis for the physical development of the built environment that is adaptive and transformative to the uncertain and rapid changes in urban areas. This study aims to identify the physical form that is expected to represent the character of the development of Indonesia’s urban areas in Yogyakarta as the ‘Inner City’ and Semarang as a ‘Coastal City’. The research used an NDBI map within two different timescales to identify the figure and ground of both case studies to generalize the urban tissue pattern. The initial results show that the two districts have a similar tendency to develop heterogeneously and dispersed with the predominant configuration of figures arranged through field blocks and open system urban fabric. However, the two districts also have differences that represent the physical characteristics of the inner city in the form of a low-density continuous development pattern and a coastal city in the form of a linear development pattern. The characters show the process of shifting from closed urban fabric to open-fragmented peri-urban fabric.

Public transportation in Jakarta is one of the leading facilities which currently being improved by the local government. Transportation facilities in Jakarta are now being strived to be integrated. However, not all areas in Jakarta have access to public transportation. This study aim to show how public transportation, especially in Central Jakarta, can be reached by pedestrians. This research used a geographic information system-based approach for assessing pedestrian accessibility in metropolitan areas, focusing on access to public transportation stops and stations. This methodology attempts to provide integrated methods to urban planning and mobility planning and decision-making assistance, with the dual goals: (1) supporting sustainable and non-motorized mobility, and (2) also boosting the appeal of public transportation. There are two main steps in method. First, identify the pedestrian walking zone of urban spaces around public transportation nodes; and second, mapping the access times to create a detailed pedestrian isochrones, and calculate how residents (or how many opportunities and facilities) are well served by the public transportation system to measure accessibility levels. This study indicates that some of the main areas already have integrated public transportation facilities, but the stopping distance is quite burdensome for pedestrians to access.

Authors: Relissiana  , Marhaento H , Subeno
Published: September 2022

Sermo Wildlife Sanctuary (SWS) is a habitat of barking barking deer (Muntiacus muntjac) that is included as one of the protected species according to Ministerial Decree of Forestry and Environment No. 92/2018. The latest report from the authority, the Yogyakarta Natural Resources Conservation Agency (BKSDA Yogyakarta), stated that in 2017, it was estimated that there are only six individual barking deer inside the SWS. Their existence is threatened due to several activities such as tourism and agriculture practices. It should be noted that SWS was formerly a production forest so that local communities have been used to involve in forest management. Apparently, after the forest status has been changed into a protected area, the activities inside the forest are still remaining and thus potentially result in disturbing the barking barking deer habitat. This study aims to assess the extinction risk of the barking deeper inside the SWS. This study used the Spatial Multicriteria Analysis (SMCA) through Geographical Information Systems (GIS) technique to assess the extinction risk of barking deer in SWS. Theresults show that 137.21 hectares or 73.77% of the total area of SWS is an area that is prone to barking deer habitat. Therefore, it is necessary to take conservation measures and increase supervision so that habitat threats can be minimized.

Published: September 2022

Ambon City has limitations in the development of residential areas because it is in an area prone to earthquake disasters, This is because Ambon City is in a very active tectonic area and 65% of settlement land / land built in Ambon City is in an active and weak fault zone and if there is a plate movement there will be an earthquake along the weak zone. One of the first steps to the effort to stigmatize disasters is to estimate how large the area of settlements that have been analyzed using cellular automata markov-chain located in earthquake-prone areas. This study aims to analyze changes in Ambon city land cover in 2012, 2017, 2021 and predict land cover in 2031 and synthesize spatial dynamics of settlement land availability with earthquake-prone areas in Ambon City in 2021 and 2031. This study uses Cellular Automata modeling to predict ambon city land cover in 2031 which will be covered with a map of earthquake-prone areas obtained from BPBD Ambon City to see residential areas that are in earthquake prone areas in Ambon City in 2021 and 2031. The results showed that the area of built land affected in earthquake-prone areas has a straight proportional relationship with the year of land development built. So that the more years then the area of land is built in areas prone to earthquakes and increasing. This research is expected to be used as a reference in the management of sustainable settlement area development and for efforts to organize space based on disaster mitigation in order to minimize losses and casualties due to earthquake disasters that will occur in Ambon City in this future.
