Abstract: Climate change has a greater effect on the long-term viability of coastal environments and people’s livelihood. The idea of using ecosystems to help people deal with the effects of climate change is becoming more common at the international, national, and local levels, especially when it comes to spatial planning. So, learning about spatial planning-based ecosystem adaptation (SPBEA) is important for early careers because they will be the ones who have to deal with the decisions made now. Coastal communities must also understand the steps they can take to lessen the effects of coastal disasters in their area. This study looks at how the SPBEA concept can be taught to early-career practitioners and coastal communities through training and workshops, and the effectiveness of online training in transferring knowledge. The method of training used the hybrid method for comparison. A hierarchical approach was taken, starting from the compilation of SPBEA teaching materials, followed by SPBEA training for early-career practitioners to generate SPBEA zoning and transferring the training results to the coastal communities. Online training is not as good as offline one, but it was advantageous for the participants. Indeed, the pond-farming community was excited about the implementation of SPBEA.

Abstract: Forest fires in Indonesia are 99% due to human intentional factors. The practice of burning forests is done because it is easy, fast, and inexpensive, and the assumption that the ashes produced will fertilize the soil. The practice of burning forests is done primarily for the purpose of clearing agricultural land and plantations. Land and forest fires will be even worse if they occur on peat lands. Fires on peat lands consist of crown fire, surface fire, and ground fire which have a more severe impact on environmental, social and economic impacts. In terms of management, it is also more difficult and longer than fires on mineral land. On the other hand, pea tlands in Indonesia, 30%, are peat lands that have the potential for agricultural and plantation cultivation. The main objective of this paper is to use spatial modeling to provide an early warning system for forest fires on peat lands based on anthropogenic aspects in the Meranti Islands Regency, Riau Province. Data compiled based on anthropogenic aspects include: accessibility, population distribution, land clearing patterns, land use, and land status. Spatial analysis was carried out on anthropogenic aspects and the distribution of hotspots that had a level of confident (c 80%). The results of the paper indicate that anthropogenic aspects that are dominant in the occurrence of forest fires are accessibility of road than river.

Abstract: The acquisition of dynamic coastline change at fine spatial and temporal resolution is essential for enhancing sustainable coastal economic development and coastal environmental conservation. Port construction, land reclamation, urban development, and sediment deposition have resulted in extensive coastline change. In this study, the coastlines along the 56 coastal countries in 1990, 2000, 2010, 2015, and 2020 were delineated and classified into six categories using Landsat time–series images. Five relevant indices, i.e., the length, length ratio, length change rate, index of coastline utilization degree (ICUD), and fractal dimension (FD), were calculated to analyze and explore the spatiotemporal pattern of the coastlines. The results indicate that: (1) The overall length of the coastlines has increased from 3.45 × 105 km to 3.48 × 105 km in the past 30 years, with a net increase of nearly 3904 km. Between 1990 and 2020, the length of the artificial coastline increased by about 13,835 km (4.9~8.8%), while the length of the natural coastline decreased by 9932 km (95.1~91.2%). The increase in artificial coastline is concentrated in Southeast Asia and South Asia. (2) The coastline fractal dimensions (FDs) of countries and continents show that the average FD values of countries in South Asia (1.3~1.4) and Southeast Asia (1.2~1.3) were higher than other countries in the study regions, meaning that the coastlines in South Asia and Southeast Asia are more complex and curved. (3) The value of the ICUD index increased consistently between 1990 and 2015 (177.7~186.6) but decreased sharply between 2015 and 2020 (186.6~162.4), implying that the impact of human activities on the coastline continued to increase until 2015 and began to decrease after 2015. Our study examined the changes in various types of coastlines, which could be significant for sustainable development and environmental protection in coastal areas.

Abstract: Fishers residing in small islands are heavily dependent on the surrounding resources. The dynamics of these resources influence the fishers’ level of resilience. The purpose of this study is to analyze the correlation between the fishers’ resilience and available resources using a dynamic model. The method used is dynamic system analysis. The research site is located in is Karimunjawa islands, Central Java, Indonesia. The primary data collection was conducted between March-April 2018. The dynamic model consists of ecological and economical subsystems. The findings show that fishers’ resilience experienced a downward trend yearly. Based on the simulation of resources dynamic on the Karimunjawa islands, changes in resource conditions forced fishers to adapt to ongoing changes. The dynamics of marine and fishery resources in the Karimunjawa Islands have forced the fishers to adapt to the changing conditions. The adaptation made is that fishermen change their fishing grounds, especially as they adopted a new technology of GPS and fishfinder . Efforts can be made to improve the fishers’ resilience by increasing their productivity and fishing results. It can be achieved by improving the fishers’ capacity through training programs to improve their fishing skills.

Abstract: Ecosystem-based adaptation to climate change impacts, such as shoreline retreat, has been promoted at the international, national, and even local levels. However, among scientists, opinions about how to implement it in spatial-planning practices are varied. Science-based environmental factors, human wellbeing, and sustainable development can be strengthened by developing spatial-planning-based ecosystem adaptations (SPBEAs). Therefore, this article aims to assess how the SPBEA model can be developed within an area prone to shoreline retreat. A coastal area of the Sayung subdistrict in Central Java, Indonesia, was selected as a study area because it has experienced a massive shoreline retreat. A multicriteria analysis (MCA) method was employed for developing the model by using the geographic information system (GIS) technique of analysis, ided into three steps: the fishpond zone determination, which involved the analytical hierarchy process (AHP) method in the process of model development the fishpond site determination SPBEA fishpond site development. The results show that the SPBEA model is the best practice solution for combatting shoreline retreat because of tidal waves and/or sea-level rise. The spatial site management should empower the coastal protection zone and the sustainable fishpond zone by implementing a silvofishery approach.

Abstract: Marine spatial planning has become the crucial issues for an archipelagic state such as Indonesia. The global market demand on marine economic species has been initiated the exploitation of the marine species which will become the hindrance in maintaining the sustainable marine bio ersity. Besides that, the degradation of marine species will also become the problem for traditional fishermen. Therefore, a model has to be employed to spatially manage the coastal waters as the alternative for fishermen activities during closed seasons, such as floating fish net culture. The aim of this study was to develop marine spatial planning model based on ecological approach in order to identify the potentiality of marine waters for marine culture such as floating fish net culture. The method for the model consisted of social assessment using the Delphi for developing the rule of marine planning for floating fish net culture and the spatial analysis technique for determining the model of marine spatial planning for floating fish net culture. The area of Kupang Bay waters, East Nusa Tenggara was used as the study area. The result indicated that the model can be used to sustainable marine spatial planning, especially for floating fish net culture. The model considered the aspects of potential area for marine culture, the management of zonation and transportation lanes, the conservation and protected area and the strategic area. Application in Kupang bay illustrated the aspect of technology input such as raceways since the majority of the area of Kupang Bay waters is classified as medium potential. Further research still needs to optimum the application of model to others marine area.

Abstract: This research aims to protect Digital Elevation Model (DEM) data from piracy or counterfeiting. An invisible watermark inserted into the data, which will not considerably change the data value, is necessary. The proposed method involves the use of the two-dimensional discrete cosine transform (2D DCT), a combination of 2D DCT and discrete wavelet transform (DWT), and two-dimensional discrete Fourier transform (2D DFT) in the frequency domain. The data used include a National DEM file downloaded from the geoportal of the Geospatial Information Agency (Badan Informasi Geospasial—BIG). Three files represent mountainous, lowland/urban, and coastal areas. An “attack” is also conducted on the watermarked DEM by cropping. The results indicate that the watermarked DEM is well recognized. The watermark can be read 100% for 2D DCT, while that for 2D DFT can be read 90.50%. The distortion value of the elevation data under the DCT technique demonstrates the smallest maximum value of 0.1 m compared with 4.5 and 1.1 m for 2D DFT and 2D DCT–DWT. Meanwhile, the height difference (Max Delta), the peak signal-to-noise ratio, and the root mean squared error (RMSE) are highest in mountainous, lowland, and coastal areas, respectively. Overall, the 2D DCT is also superior to the 2D DFT and the2D DCT–DWT. Although only one can recognize the nine watermarks inserted on each sheet, DEMs attacked by the cropping process can still be identified. However, this finding can sufficiently confirm that DEMs belong to BIG.

Abstract: Land degradation (LD) is an important issue worldwide because it affects food production and people’s welfare. Many factors cause land degradation, but in humid tropical areas, erosion is the main factor. More than 100 countries including Indonesia are affected by LD. Watershed management should be prioritized owing to budget constraints, while on the other side, the area affected by LD is very large compared to the size of the existing land area. The middle Citarum sub-watershed (MCSW) is one of the most degraded drylands in Indonesia, where the environment can be considered a typical humid tropical watershed. The objective of this study was to map degraded lands and prioritize restoration using a combined approach of the universal soil loss equation (USLE), the analytical hierarchy process (AHP) and geographic information systems (GIS) in a multiple-criteria decision analysis (MCDA) environment. The severity of LD was estimated quantitatively by analyzing the parameters of land use and land cover, slope, soil erosion, productivity, and management. The results indicated that the MCSW is dominated by the potentially degraded land classes (38%), followed by the degraded land classes (21%). The prioritization of LD restoration is suggested in the area of very high and high degraded land. The method developed in this research work could be adopted as a tool to guide decision-makers toward sustainable land resource management in humid tropical watersheds affected by LD.

Abstract: Experiences with natural disasters have intensified recent efforts to enhance cooperation mechanisms among official disaster management institutions to community participation. These experiences reveal a need to enhance rapid mapping technical assistance to be developed and shared among young scientists through a summer school. However, the question arose of how effective this summer school to be used as a tool to increase scientists’ understanding and capacity. This study sought to evaluate the extent to which human resource capacity building can be effectively implemented. The methods used for this evaluation is through observations, questionnaires and a weighted scoring based on knowledge, skills and attitudes’ criteria. The results indicate a significant improvement in knowledge (94.56%), skills (82%) and attitudes (85.20%) among the participants. Even though there are still gaps in participants’ skills, the summer school was found to be an effective way to train the young scientists for rapid mapping.

Abstract: Natural disasters are natural phenomena that cannot be avoided by humans, but human beings are able to mitigate its impact for the humanitarian aspects. Therefore monitoring, predicting and managing natural phenomenon in the earth is one of the methods to mitigate disaster - one of them by using remote sensing technology. Integrated of imageries from near real-time remote sensing satellite system to the higher resolution with the support of the ancillary data may develop spatial information for any mitigation purposes. Therefore, the aim of the study is to assess rapid information of the prone area and the possibility of developing a projection model with the remote sensing approach. The steps included the assessment of prone area by implemented the integrated method of NDVI, fussy and high pass and the overview of the projection model using remote sensing approach. The disasters associated with landslides may be used for ex le, because this disaster often struck the Asian region. The result of the assessment indicated the integration of NDVI, fussy and high pass method can give faster information of the landslides hazards that is needed for disaster and humanitarian institutions. Meanwhile, to develop a projection model for the hazards cannot be developed only on remote sensing technique, but better support by GIS technique and other in situ ancillary information.

Abstract: The drivers for coastal flooding may vary from extremely high intensity and persistent rainfall, morphological factors of the coastal area, to extreme waves from the ocean. This means that the flood vulnerability of a coastal area does not solely depend on a single driver but can be a combination with others. A national standard for coastal flooding based on rainfall drivers has been developed. As an evaluation, this study aimed to develop a method for coastal flood-prone mapping by combining rainfall with tidal waves. The steps included the assessment of the coastal flood-prone areas driven by rainfall (CFR) and the coastal flood-prone areas by combined drivers (CFC), which was developed by employing the analytic hierarchy process (AHP), spatial-overlaid, weighted-scored, and logical tests. The coastal area of Mataram City on the Island of Lombok in Indonesia was selected as the study area, since it is frequently affected by flooding. The findings determined the essentiality of the CFC method for identifying flood vulnerability areas. Thus, the minimum standard for CFC parameters can be defined with climatic and land characteristic factors. Further, the findings also identified the need for expert judgment in the development of the CFC weighted score-based method.

Abstract: Port cities in Southeast Asia (SEA) have been undergoing intensive land use and land cover change (LUCC) because of rapid socio-economic development in recent decades. However, various development statuses among these cities could result in ergent LUCC transitions and therefore affect the local ecosystem at different levels. This study investigated the historic land-use transition in the SEA port cities by classifying Landsat images from 1990 to 2020 with the random forest algorithm, and further integrated these patterns with land-use modeling to inform the future land uses under the current developing mode. DIVISON was used to assess land-use fragmentation and investigated its relationship with development levels represented by the average nighttime light index (ANLI). The results showed an intensive LUCC in SEA port cities in 1990–2020, with artificial surface increasing by 9.2% (175.9 km 2 ) of the total area, mainly converted from cultivated land which decreased by 136.9 km 2 . An inverted V-shaped relationship between fragmentation and development level was found at the landscape level and for cultivated land, in which both turning points (TPs) occurred in the mid-developed stage (ANLI = 41.1 and 20.0, respectively). Artificial surfaces tended to be more aggregated in later developed stages, showing a TP of ANLI around 53.2. Under the current developing mode, the aggregation trend will be generally continued for the next three decades, mainly resulting from the increased connection in artificial surfaces. The findings also highlighted a tradeoff between city development and agricultural production in SEA port cities, leading to increased food insecurity in more developed stages. Recent developments also negatively affected aqua ecosystems, such as aquaculture, mangroves, and natural waterbodies in several cities. This study underscored the importance of the sustainable LUCC strategy in SEA port cities and provides insights into rationalizing land-use policies for other port cities worldwide.

Abstract: Indonesian waters hold the world’s mega bio ersity of coral reefs. However, a range of anthropogenic pressures are threatening the coral reefs persistence. Since the early 20 th century, remote sensing data has been assessed to map and monitor coral reefs. The reef habitats are monitored at various hierarchical spatial scales using integrated remote sensing and field data, but the level of detail and accuracy at a single point still questionable. Therefore, this study aims to assess the coral reefs methodology based on an integrated digital image processing approach. The method will employ a multi-pair and a single pair or an initial pair of Depth Invariant Index (DII) transformation bands, pixel-based Isodata and K-Means algorithm, and supervised classification method based on maximum likelihood and nearest neighbor algorithms. Object-based classification images, training areas, and data references were supported by previous research. The findings indicate that the maximum likelihood algorithm is better to apply for supervised classification for a single transformation band, while the K-Means algorithm is better for pixel-based classification since better accuracy can be obtained. However, various remote sensing data, band combinations, and clusters may affect the difference in results.

Abstract: The disharmony between land and marine spatial planning is threatening the planning of sustainable coastal development. In Indonesia, land spatial planning has firstly been implemented, followed by the spatial zonation of coastal waters. Therefore, to achieve sustainable coastal zone management, the harmonization between the regional spatial plan or RTRW with the zoning plan for coastal waters and small islands or RZWP3K is urgently needed. This paper aims to examine the spatial problems in the process of integrating these two spatial plans. Using the spatial review method, the stages of study consist of forming the seamless spatial planning maps of 8 provincial regions in Indonesia that have stipulated the second regional regulation on spatial planning regimes and then integrated them with the coastal waters spatial planning zonation map (rzwp3k). The findings show the potential conflict in some areas, especially in protected areas with cultivation and public use, and between the cultivation areas, fisheries, and industries. Other findings are on the technical aspect, which shows the differences in the coastal area due to the use of two different coastlines and base maps. Regarding substance, there are differences in the content of the framework of the RTRW and RZWP3K mandates in regional regulation.
