Abstract

This study aims to identify and analyze mitigation and adaptation to natural disasters carried out by the Mentawai tribe. This study uses a qualitative research type with an ethnographic approach. Determination of informants in this study used the snowball sampling method, a sampling technique that starts with a small number then develops along with the data collection process. Data collection techniques: direct observation in the field, interviews, documentation, and literature studies. Data analysis was carried out through the stages of data collection, data reduction, data presentation, and drawing conclusions. Results of this study indicate that there are two models of natural disaster mitigation based on local wisdom, namely the stilt house (Uma) which is located in coastal communities and arat sabulungan which is located in hilly communities. Local wisdom of Uma which is located in coastal areas is used and trusted for mitigating earthquakes, tsunamis and floods. Local wisdom of arat sabulungan for mitigating landslides in the Mentawai hills. This study also shows structural adaptation strategies, socio-cultural adaptation and economic adaptation of the community in dealing with natural disasters in the Mentawai Islands region. Conclusion is that with local wisdom, communities are able to maintain the existence of their lives.

Abstract

This study aims to assess the carrying capacity of the Anai River Basin (Watershed) in West Sumatra Province in response to increasing anthropogenic pressures and environmental changes. The research employed a spatial analysis approach utilizing remote sensing data and geographic information systems (GIS) to evaluate land cover conditions, water quality, and erosion levels. Carrying capacity analysis was conducted by calculating an environmental carrying capacity index, which included hydrological aspects, water quality, and the ecosystem's capacity to provide environmental services. The results indicate that the Anai River Basin is experiencing significant ecological pressure from land use changes, particularly the conversion of forests into agricultural land and settlements. Erosion rates in several sub-watersheds reached moderate to severe categories, with an average value of 15-25 tons/ha/year. River water quality demonstrated a decline in several parameters, especially increased turbidity levels and sediment content during the rainy season. The hydrological carrying capacity of the Anai watershed remains in a moderate category (index 0.65) but has shown a declining trend over the last five years. The findings indicate the necessity for implementing sustainable watershed management strategies. Management recommendations include forest conservation in upstream areas, the application of soil and water conservation techniques on agricultural land, the development of a regular water quality monitoring system, area zoning based on vulnerability levels, rehabilitation of 2,500 hectares of critical land, and the strengthening of watershed management institutions involving the active participation of local communities.

Abstract

As centers of academic activity, universities generate significant waste volumes requiring systematic and sustainable management. This research aims to analyze the current state of waste management at Universitas Negeri Padang (UNP) across technical-operational, socio-institutional, economic, and regulatory dimensions; assess the participation level of the academic community; and formulate an efficient, sustainable development strategy. This study employed a qualitative descriptive method with a case study approach. Data were gathered through observation, interviews, questionnaires, and documentation studies. The strategic framework was developed using SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis, supported by Internal Factor Analysis Summary (IFAS) and External Factor Analysis Summary (EFAS) matrices. The findings reveal that UNP’s current waste management remains conventional (collect-transport-dispose), handling 1.5 to 2 tons daily without integrated source-sorting. SWOT analysis identified strong internal legal foundations and a large human resource pool as primary strengths, while the conventional system and low community participation constitute main weaknesses. Although external threats include public apathy and landfill dependency, significant opportunities exist through governmental regulatory support and potential collaborations. With an IFAS score of 1.1 and an EFAS score of 0.29, UNP is positioned in the aggressive strategy (SO) quadrant. Furthermore, economic valuation indicates a potential daily revenue of IDR 1,545,100 from recyclable waste, highlighting the viability of an integrated system. To achieve sustainable management, UNP must leverage its internal strengths to seize external opportunities. The study recommends a transition from conventional methods to an integrated model by strengthening internal regulations, optimizing 3R (Reduce, Reuse, Recycle) infrastructure, implementing sustainable education programs, and fostering multi-stakeholder partnerships.
