“…By referring to the value of losses, it is necessary to carefully consider the management of coastal areas in an effort to mitigate coastal flood disasters [12]. However, the coastal flood disaster conditions may become more severe in the future due to the contribution of global warming which causes an increase in sea surface height [14], and weather anomalies resulting in various hydrometeorological disasters in coastal areas [3,4].…”

Batam City, strategically located as an economic and industrial center in the Riau Islands province, Indonesia, faces challenges stemming from rising sea levels due to climate change and unusual tidal patterns. These factors lead to recurrent coastal flooding and create new issues for coastal areas. This research project has three primary objectives: tidal forecasting, tidal flood hazard mapping, and vulnerability assessment of infrastructure and settlements in Batam City's coastal areas. To achieve these goals, a combination of methods is employed. Tidal forecasts rely on a semimean linear trend approach. Spatial flood analysis considers the Hloss scenario, with the loss distance referring to the peak of the sea flood. Additionally, losses resulting from coastal flooding disasters were assessed using the Economic Commission for Latin America and the Caribbean (ECLAC) budget base planning (RAB) method. The research results reveal that the Batam area experiences two semidiurnal tides with dynamic sea level fluctuations, reaching a peak flood height of 2 meters. Spatial analysis identified several areas affected by tidal flooding, particularly densely populated coastal areas such as Batuaji, Batuampar, Sekupang, and Bengkong subdistricts. These areas, characterized by tidal flats, are particularly vulnerable to significant coastal flooding during high tide. The impact extends to key infrastructure, including roads, mosques, housing, and social facilities, resulting in estimated losses. The number of buildings affected by flood on Batam City is 12,681 units, and the flood affected area covers approximately 10,975.76 hectares, with road infrastructure costs amounting to about US$337,131.36. Field investigations also reveal that several settlements in the region have initiated flood protection measures. However, many settlements are still directly affected, underscoring the immediate need to improve environmental quality in this area.

“…(Barun, 2017) The plantation is a real challenge and threat to the ecosystem and biodiversity. This land expansion activity is a challenge for the preservation of the peatland ecosystem (Hanif et al 2017(Hanif et al . 2019 where a pure circle of the ecosystem and many native species are less frequent within plantations than within native forests, decline species population and many incident conflicts between animal and human because of the development of plantation area on the peatland ecosystem in Riau (Saavedra andSimonetti, 2005, Uryu, 2008).…”

Peatlands are the stretch of ecosystem landscape with unique characteristics, both physically, chemically, and biodiversity. Anthropogenic activities in peatland use and disasters pose a threat to the preservation of the peatland ecosystem, which has impacts toward abiotic to the element of biodiversity (biotic). The purpose of this research is to model how the threat of the peatland ecosystem by using spatial data modeling. The method in this research using cloud-based GIS data analysis from Google earth engine, modeling distance parameter to variable modeling of interaction among landscapes on the peatland, and weight sum the value over raster-based spatial layer to determinate the thereat in the peatland ecosystem. The results of this study found zones where hot spots often occur. Modeling with euclidean distance to all modeling variables (except temperature) gives a clear effect on how the threats from each landscape interact with each other. We found that the threat of peatland damage in the high threat class dominates the plantation area reaching 30.9% of the total peatland area, whereas the forest landscape only has a high threat with a percentage of 1.9% and a low threat which the ecosystem is stable and natural reaching over 34.7 %. From this model, we succeeded in bringing up the idea to determine the priority area for policies where need to be done in handling the protection of peatland ecosystems, especially in plantations where the highest percentage of the ecosystem threat is in the high level with integrated peatland management.

“…To identification agricultural changes we use spatial analysis, which to obtain the information about the land cover can also by interpreting the Imagery [9]. Where image analysis process used multi spectral satellite image classification, this techniques used algorithm Maximum Likelihood as part of supervised classification, which is known as a well-established image classification statistical model in grouping pixels for land cover identification [10]. It possible to compute the statistical probability of a pixel vector being a member of each spectral class [11].…”

Techno-ecological agriculture seeks to combine the strengths of ecological agriculture with technologically advanced agriculture, so that a more productive, efficient and quality agricultural model with less risk and environmentally friendly will be formed. Population growth will encourage people to open new agricultural lands, causing a decrease in the carrying capacity of agricultural land. The objectives of this study are (1) to analyze land use changes in the city of Padang in 2007 and 2019, (2) to analyze the benefits of the techno-ecological agricultural model in determining the capacity of land in the city of Padang, (3) to calculate the carrying capacity of land for food as a result of its application. Techno-ecological agricultural model in Padang City. This study uses an approach, namely a quantitative descriptive approach, with these variables concerning changes in land use, land capability and carrying capacity of agricultural land for food crops. The population in this study were all areas in the city of Padang consisting of 11 districts, while the sample was areas that were only planted with rice. The results of the study describe (1) The change in paddy fields occurred from 2007 covering an area of 7,266,815 hectares, while in 2019 it decreased to 5,263,489 hectares. (2) Land capability for class III covering an area of 1,399.85 ha, Class IV covering an area of 21,870.08 ha, Class VI covering an area of ?? 4,048.8, and class VII covering an area of 41,051.37 ha, (3) Carrying capacity of food land for rice fields in Padang City produces a value of 0.051 which is included in class III, which means that the city of Padang is an area that has not been able to do food self-sufficiency.
