Abstract

The coastal area of Ternate Island has a high potential for tsunami disasters and complex tectonics. The tsunami on Ternate Island was triggered by an earthquake in the Maluku Sea and the eruption of Mount Gamalama under the sea. The rapid development of Ternate, especially in the tourism sector, such as Loto Agrotourism Village, West Ternate, demands attention to the safety of visitors and residents. The main problem in Loto Village is the lack of evacuation routes, so an effective evacuation strategy is needed to minimize losses during a tsunami disaster. This study aims to determine evacuation routes using UAV data and participatory mapping in Loto Village, Ternate City. UAV aerial photos were processed using photogrammetry techniques with Agisoft Metashape Professional software, producing Ortho-Mosaic Maps and Digital Elevation Model (DEM), which were analyzed in QGIS software. The ortho-mosaic map was overlaid with a tsunami hazard map to create temporary evacuation routes and points (TES), which were confirmed through participatory mapping. The Final Map shows four TESs, which are accessible via footpaths, side roads, and main roads. In the event of a tsunami, tourists and residents in the Lota Agrotourism area can use this map for evacuation. The map can also be an important reference for the government in forming disaster mitigation policies to ensure the safety of tourist destinations that are vulnerable to tsunamis.

Abstract

Currently, the role of local wisdom in agricultural land protection practices appears to be diminishing due to modernization, generational changes, and shifts in agricultural production orientation, posing a challenge to the sustainability of agriculture. This study aims to: (1) examine the types of land degradation occurring in terraced lands; (2) analyze the types of local wisdom-based land protection practices still applied by terraced land farmers; and (3) assess the influence of local wisdom-based land protection on the productivity of terraced agricultural land. From a population of 504 farmers, a sample of 100 was selected using Slovin’s formula with a 10% margin of error through simple random sampling. Additionally, 10 key informants were included, comprising farmers, farmer group leaders, and village officials. Primary data were collected using semi-structured questionnaires and in-depth interviews with informants. Sensitivity tests were conducted to ensure data consistency and validity. Data were processed using SPSS 28, and the results were presented in graphs and analyzed using descriptive qualitative methods, supported by findings from in-depth interviews. The study found that soil erosion and micro-landslides on terrace embankments are the most dominant types of land degradation experienced by farmers, which significantly affect agricultural productivity. To address these issues, farmers implement local wisdom-based land protection practices, including constructing bench terraces, using organic fertilizers derived from agricultural waste, collaboratively repairing irrigation channels, and prohibiting the burning of waste. Empirically, these practices have been able to maintain and even improve agricultural productivity.

Abstract

Regional spatial planning often requires studies of projected land-use changes. However, these land-use change projection studies often neglect the protection function aspect in their modeling scenarios. Modeling using protection function scenarios is expected to make a significant theoretical and practical contribution to regional spatial planning and geospatial analysis. The research aims to develop a model for projecting land use change based on protected scenarios to support sustainable development in Malang City. Projection of land-use change based on scenarios is carried out quantitatively and involves spatial modeling. Spatial modeling was carried out using Cellular Automata (CA), which is integrated with Markov Chain (MC) and Artificial Neural Network (ANN). Hybrid modeling of Cellular Automata (CA) – Markov Chain (MC) – Artificial Neural Network (ANN) is expected to offer more attractive advantages compared to single modeling techniques. The model was developed by paying attention to the driving factors and constraint variables as scenario variables in the form of maintained protected areas. This research produced a projected model of land use change in 2029 based on a protected scenario in Malang City. The projection results indicate potential land change for sizable settlements in Malang City, especially in the eastern and western parts around the center of activities and the Malang-Pandaan toll road. The potential development of these settlements needs to be anticipated and directed so that they do not cause various spatial conflicts in the future and do not trigger environmental degradation. With scenario-based projections, several protected areas such as city parks, green belts, city forests, and river banks can be relatively maintained in 2029 according to the spatial pattern plan in the Malang City spatial plan.

Abstract

Uncontrolled land-use changes driven by rapid population growth and expanding residential development have significantly heightened flood risk in the Kendal Watershed, Kendal District. The conversion of agricultural and open land into built-up areas has altered hydrological processes, reducing water infiltration capacity and increasing surface runoff. This study aims to (1) identify spatial and temporal land-use changes from 2017 to 2025, (2) analyze public perceptions regarding land conversion and flooding, and (3) assess the resulting social and environmental impacts within the watershed area. A quantitative descriptive approach was employed by integrating Geographic Information System (GIS)-based analysis of Sentinel-2A satellite imagery with primary data collected through Likert-scale questionnaires administered to 96 respondents residing in flood-prone areas. The results indicate a substantial decline in rice field areas by 44.19 hectares, accompanied by a notable increase in residential land of 36.12 hectares over the study period. Community perceptions reveal that these land-use changes have contributed to increased flood frequency, greater flood intensity, and longer inundation duration. The observed social impacts include disruptions to daily activities, reduced access to clean water, economic losses, and a higher incidence of waterborne and skin-related diseases. Environmental impacts are reflected in declining sanitation conditions, increased waste accumulation, river sedimentation, and persistent water pollution. These findings underscore the urgent need for stricter land-use regulation, restoration of green and infiltration areas, and adaptive, sustainable spatial planning to reduce flood risk and enhance community resilience in the Kendal Watershed
