Minyak nabati merupakan sumber lemak esensial yang memiliki nilai gizi dan manfaat kesehatan tinggi, namun kualitasnya sangat dipengaruhi oleh proses ekstraksi. Metode konvensional seperti ekstraksi pelarut dan mekanik memiliki berbagai keterbatasan, termasuk waktu proses yang lama, penggunaan pelarut tinggi, serta degradasi senyawa bioaktif. Oleh karena itu, sonikasi atau Ultrasound-Assisted Extraction (UAE) menjadi alternatif teknologi modern yang efektif dan ramah lingkungan untuk meningkatkan efisiensi dan kualitas hasil ekstraksi minyak nabati. Teknologi ini memanfaatkan gelombang ultrasonik yang menghasilkan efek kavitasi, sehingga mempercepat pemecahan dinding sel dan pelepasan senyawa target. Kajian ini bertujuan untuk menelaah efektivitas teknologi sonikasi dalam meningkatkan kualitas dan kuantitas hasil ekstraksi minyak nabati dari berbagai bahan sumber, berdasarkan analisis literatur terkini. Hasil kajian menunjukkan bahwa sonikasi mampu meningkatkan rendemen, memperpendek waktu ekstraksi. Dengan demikian, sonikasi merupakan teknologi prospektif dalam produksi minyak nabati berkualitas tinggi.

This research explores cultural preservation strategies through the development of the tourism sector, using the Surakarta Palace as a case study. The Surakarta Palace, a cultural heritage site in Central Java with significant historical and cultural value, plays a vital role in preserving Javanese traditions while contributing to regional tourism growth. This study adopts a descriptive qualitative method with data collected through observation, interviews, and documentation. The findings reveal that the Surakarta Palace actively preserves culture through various initiatives such as organizing traditional ceremonies, staging classical Javanese art performances (like gamelan and wayang), and managing museums that house historical artifacts and royal collections. These strategies serve not only to maintain cultural continuity but also to increase the attractiveness of the palace as a cultural tourism destination. Despite these efforts, several challenges remain. These include limited financial resources, minimal use of digital media for promotion, and the lack of public awareness—especially among younger generations—regarding the importance of cultural heritage. To address these challenges, the study emphasizes the need for integrated collaboration between the government, the Surakarta Palace institution, and the surrounding community. Strengthening digital-based promotional strategies and educational outreach is also considered essential to increase public engagement and sustainable tourism impact. In conclusion, the Surakarta Palace serves as a strategic model for cultural preservation within the tourism framework. By improving stakeholder cooperation and adapting to technological advances, cultural heritage can be preserved effectively while supporting local economic development through tourism. Therefore, cultural preservation and tourism development should be positioned as complementary efforts, where the sustainability of both depends on strategic planning, inclusive participation, and adaptive innovation in facing the dynamic demands of modern tourism.

Kebun Raya Mangrove (KRM) Surabaya is the first thematic botanical garden in Indonesia that focuses specifically on the mangrove ecosystem. It serves multiple functions, including conservation, education, research, and recreation. With its ecological uniqueness, KRM has strong potential to develop into a prominent ecotourism destination. However, post-pandemic conditions have seen a significant decline in visitor numbers, indicating the urgent need for more effective and targeted marketing strategies. This study aims to identify and evaluate marketing strategies that can enhance tourist interest and increase visitation to KRM Surabaya. The research adopts a descriptive method with a qualitative approach by collecting both primary data (through observations and interviews) and secondary data, which are then analyzed thematically. The findings indicate that KRM is currently facing several critical challenges, including limited accessibility, inadequate digital promotion, and environmental maintenance issues. Existing marketing efforts—such as affordable ticket pricing, minimal promotion via the official social media accounts of the Food Security and Agriculture Service, and limited collaboration with local SMEs—have not successfully expanded KRM’s market reach or visibility. To address these gaps, the study recommends a comprehensive marketing strategy that includes the optimization of digital marketing through official KRM-managed social media channels, strategic partnerships with ecotourism influencers, the organization of thematic events (e.g., mangrove festivals), and the innovation of mangrove-based products that can boost local identity and visitor engagement. By implementing these strategies, KRM is expected to strengthen its destination branding, attract a broader audience, and establish itself as a leading model for sustainable tourism in Surabaya and beyond.
