Abstract

This research aims to investigate the transformation of local knowledge of Lubuk Larangan toward tourism. The research method uses an ethnographic qualitative approach. This method is implemented because this research has a connection to customary societies. To gather data was used as an in-depth interview. Samples are selected through the purposive technique. The result is probed meticulously through the triangulation technique and triangulation sources. The result shows that customary community conferences locally impact the conservation of nature and fish in Lubuk Larangan. Deliberations determine the time of harvesting fish in the forbidden pit area and determine the area used as a prohibited area. There were 10 ninik mamak in attendance and one ninik mamak as the leader of the ten ninik mamak. Another finding is that democratic principles such as decisions on the basis of togetherness for the common interest are applied to the forbidden area. The last finding is that there is a transformation of social and cultural values in the Lubuk Larangan area. Customary rules are very strict, but interfering with the younger generation to overhaul traditional rules makes the traditional leaders adapt to the wishes of the younger generation to serve as fishing tourism areas. Several considerations were found at the time the Lubuk Larangan area had not been changed. The rules were detrimental because when the event opened the Lubuk Prohibition area, it resulted in the exhaustion of fish, and profits were only obtained 30 million in 3 years. When it has been converted into fishing tourism, it impacts increasing profits to reach 30 million in a month. Plus, the fish will not become extinct because the fish caught when fishing will be released again. People even get the opportunity to offer tent rental services, sell food and drinks, become tour guides, and offer to lodge for tourists who come.

Abstract

The expansion of agricultural and plantation areas, and demands for improved accessibility, particularly on gentler slopes, has accelerated deforestation in West Sumatera. This study investigates changes in forest cover in West Sumatera over the period from 2000 to 2050, using two initial cover datasets from 2000 and 2015. We used driving variables, including elevation, slope, and roads, processed through the Change Modeller in IDRISI TerrSet. Modelling results indicate that forest cover changes are significantly influenced by topography, with gentler slopes experiencing faster rates of deforestation compared to steeper areas. Regions with flat land and easy access are particularly vulnerable to large-scale conversion for agricultural use, especially for palm oil plantations. The results underscore the interplay between infrastructure development and forest cover changes, highlighting the need for careful consideration of environmental impacts in planning and policy making. This study urges the policymakers to implement strategic spatial planning and land-use monitoring to mitigate impacts of deforestation to ensure forest sustainability in West Sumatera.

Abstract

Otters (subfamily Lutrinae) consist of 13 species distributed worldwide; however, their populations have been steadily declining due to land-use changes and hunting, while information on their presence in the rice fields of 2x11 Kayu Tanam District remains undocumented. This study was conducted with the objective of identifying and document tracks and signs of otter presence in the rice fields of 2x11 Kayu Tanam District. The research was conducted from November 2023 to February 2024 using a field survey method by observing tracks, spraints, and prey remains to determine the distribution of otter signs. Based on the distribution of tracks and signs found, it is suspected that only one species occurs in the area, namely Aonyx cinereus (small-clawed otter). The presence of Aonyx cinereus in the rice fields of 2x11 Kayu Tanam District was confirmed through tracks and other signs of activity. These findings provide a foundation for further research on otter ecology in rice field ecosystems and highlight the importance of conservation efforts to sustain their habitats.
