Abstract

This study aims to determine the RTRW inconsistency index by analyzing the implementation of the Siak District Settlement RTRW, which is known from the comparison between land use and the Siak District RTRW. The land use map is generated from the SAS Planet high-resolution mind, and the settlement spatial plan map is generated from the 2020–2040 RTRW in Siak District. In addition, to find out the Siak District Settlement Spatial Plan based on disaster-prone areas, a flood disaster-prone analysis was carried out using the "weighted and scoring" method, which was then combined with the Siak District Settlement Spatial Plan Map to evaluate the suitability of settlement planning in Siak District, whether to avoid flood-prone areas or not. The results show that 33.0 percent of settlement land use is not in accordance with the regional spatial plan, and 48 percent of settlement planning is not suitable because it is in a very flood-prone area. Therefore, it is necessary for the Siak district government policy to evaluate the RTRW to be more consistent, pay attention to disaster-prone areas, and implement enforcement for spatial violators.

Abstract

Learning in the 21st century is different from learning in the past. Technological advances are growing rapidly in various areas of life, including education. With this change, it gives hope to be able to realize the nation's ideals (BNSP, 2010). The aim of this research is to see the effectiveness of using E-Comic in learning disaster mitigation material in classes XI IPS 1 and XI IPS II. The results of this research obtained an experimental pre-test score of 53.40, a post-test score of 87.10, while the control class had a pre-test score of 51.87 and a post-test score of 61.53. There was a significant increase in the Pre-Test and Posttest of the Control Experiment Class. This shows that E-Comic media can be used by educators as a learning medium in the process of learning activities at school to improve learning outcomes, increase student understanding and also be able to reduce student boredom if they only use the lecture method. Based on the response from educators, the E-Comic media developed in this research responded very well.

Abstract

Floods are the most common natural disasters in Indonesia and have enormous potential. This study aims to determine the flood hazard zone and regional arrangement in the Tarusan Watershed, South Pesisir Regency. To determine the flood hazard zone using the GIS approach. The indicators used to determine flood hazard are slope, rainfall, soil type, landform, geology, and land use. Determine the direction of regional arrangement with an Interpretative Structural Modeling (ISM) approach. The results showed that the high flood hazard zone in the Tarusan watershed is about 22% of the total area, the medium index is around 58%, and the low flood hazard index is 20%. The high - hazard zone of flood disasters in the study area is caused by high rainfall and topographic conditions of the Tarusan Watershed. The main priority in the management of flood - hazard areas in the Tarusan Watershed is to find economic alternatives to reduce forest destruction. Increasing the economic value of the community can lead to reduced community activities in carrying out land conversion, especially in forest areas.

Abstract

Mangrove and coastal ecosystems play a critical role in enhancing coastal resilience; however, their effectiveness strongly depends on governance arrangements and management strategies. This study applies a qualitative comparative case study approach integrating a Systematic Literature Review (SLR) and field observations to compare mangrove and coastal ecosystem management strategies in Padang City (Indonesia) and Port Dickson (Malaysia). A structured comparative framework was used to assess biophysical conditions, governance structures, monitoring capacity, community participation, and contributions to ecological, institutional, and social resilience. The results indicate that Padang City possesses larger mangrove extent and higher species diversity, supporting stronger ecological and social resilience, but is constrained by fragmented governance and weak enforcement. Port Dickson exhibits smaller and fragmented mangrove areas with clearer institutional authority and periodic monitoring, yet limited social–ecological integration. The findings highlight that effective coastal resilience requires integrating strong regulatory frameworks, community engagement, and consistent long-term monitoring.

Abstract

This study maps shallow coastal groundwater quality in Padang, Indonesia, using four operational parameters: potential of hydrogen (pH), electrical conductivity (EC), total dissolved solids (TDS), and salinity. We characterize spatial dependence using empirical variograms, evaluate directional anisotropy, and generate prediction surfaces with Ordinary Kriging. The variogram analysis indicates stronger spatial continuity along the coastline for EC and TDS, while salinity shows shorter continuity with a distinct directional structure, reflecting localized freshwater-seawater mixing processes. Groundwater pH remains neutral to slightly alkaline and exhibits lower spatial variability than EC, TDS, and salinity. Leave-one-out cross-validation supports the reliability of the kriging estimates at the study scale, indicating low prediction error and strong agreement between observed and predicted values. The resulting thematic maps enable a three-level quality zoning that differentiates a lower-risk northern segment, a transitional central belt, and a higher-risk southern segment consistent with seawater intrusion influence. These outputs provide a practical basis for prioritizing monitoring locations, protecting vulnerable wells, and strengthening evidence-based coastal groundwater management aligned with SDG 6 Clean Water and Sanitation and SDG 11 Sustainable Cities and Communities.
