Desa Sibandang, situated along the eastern edge of Lake Toba in North Tapanuli, Indonesia, possesses rich cultural and historical assets, including traditional Batak architecture, ceremonial stone structures, and intangible heritage such as ulos weaving. Despite being designated part of the Lake Toba Super Priority Tourism Destination (DPSP), the village has yet to realize its full potential as a sustainable heritage tourism destination. This study explores strategic revitalization opportunities by identifying internal strengths, weaknesses, and external environmental dynamics through a qualitative descriptive approach. Data were collected via 15 semi-structured interviews, field observations, and analysis of planning and policy documents. The study employed a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis followed by a TOWS matrix to formulate actionable strategies. Findings indicate a favorable internal environment (IFE score: 2.92) and a strong external opportunity landscape (EFE score: 3.02), supporting an aggressive development strategy. Key challenges include inadequate infrastructure, weak tourism governance, and limited community capacity. Strategic directions proposed include digital heritage promotion, infrastructure enhancement, cultural interpretation training, and inclusive local governance mechanisms. This research contributes to heritage tourism planning by offering a replicable framework for integrating cultural preservation with community-based tourism development. It also emphasizes the importance of ethical, participatory planning in safeguarding the cultural integrity of heritage-rich rural villages.

Grouper is one of the non-oil and gas export commodities that has the potential to be developed. As fish, fish consumption is much needed for restaurants and luxury hotels. The weight range of 500 - 100 grams / head, especially in living conditions, has a high price compared to in the form of dead fish.In 1999, research and development for multi-species harchery carried out jointly by the Gondol Marine Aquaculture Research Center with JICA first successfully produced mass of duck grouper seeds, cromileptes altivelis and tiger grouper seeds (Kawahara, et. Al ., 2000; Sugama et.al., 2001). Whereas to mass produce sunu grouper seeds in 2005. Technology development has been disseminated to government and private hatcheries, so that the production of duck grouper seeds has increased dramatically and more than 1 million seeds in 2001 (Kawahara and Ismi, 2003). This technology is also applied to the production of tiger grouper seeds, Ephinephelus fuscoguttatus by private hatcheries. In 2002, tiger grouper seed production was more than 2.6 million. For sunu groupers up to now, more than 0.5 million in 2006.Belawan Sicanang Village Medan Belawan District Medan City is an island surrounded by several tributaries which empties into the Deli River. 40% of the population are fishermen who are looking for shrimp or fish in the river and land pond farmers. Grouper is one of the fish that lives naturally in the waters of Belawan Sicanang Village which has high economic value. But environmental damage such as logging of mangroves due to the low alternatives of community livelihoods, changes in the function of land, continuous capture of the land causes the grouper population to continue to decline.The use of the river for floating cages in grouper aquaculture can reduce the reduced supply of groupers from the natural habitat of fishermen's catches produced by this region. Cheaper cost analysis compared to terrestrial aquaculture can improve the welfare of fishermen and support culinary commodities in the development of Mango Sicanang ecotourism which is being promoted by the community and the local government.
