Abstract

Mangrove ecosystem-based education is very relevant in supporting contextual learning, especially for students living in coastal areas. This program aims to improve students' understanding of mangrove ecosystems through direct exploration at Bale Mangrove Ecotourism, Poton Bako Village, as a natural laboratory. This research uses the Service Learning method with a focus on developing mangrove ecosystem-based teaching materials. The development process was carried out through interviews, observations, and field tests with students of SDN 4 Jerowaru. The results of the community service program conducted by the Bale Mangrove Thematic KKN team from the University of Mataram show that mangrove ecosystem-based teaching materials can increase students' understanding and awareness of the importance of mangroves. Learning conducted in a real and contextual environment allows students to better understand and apply scientific concepts in everyday life. In addition, this program succeeded in increasing students' knowledge about mangrove ecosystems.

Abstract

Bale Mangrove ecotourism in Poton Bako Hamlet, Jerowaru Village, East Lombok, attracts domestic and international tourists, opening up opportunities for MSME players to expand their markets. However, limited English language skills among MSME actors hinder effective interaction with foreign tourists. This study aims to improve the English language skills of MSME actors through English language training that focuses on tourism communication and English-based menu creation. The program, which was implemented between July and October 2024, showed an increase in English language skills among participants, as well as success in creating English menus that facilitate interaction with foreign tourists. This program increases the competency of MSME players in serving international tourists and supports the development of Bale Mangrove Ecotourism as a sustainable destination.

Abstract

Sesuvium portulacastrum is a coastal plant resistant to high salt content and drought. Exploration of rhizosphere bacteria is necessary to obtain potential isolates that can be developed as biofertilizers in the future. This study aims to isolate and identify rhizosphere bacteria from Sesuvium portulacastrum that are able to produce Indole Acetic Acid (IAA) and dissolve phosphate, and to test their effects in vitro on the germination of Vigna radiata L. Rhizosphere bacteria from the Bagek Kembar Mangrove Ecosystem Area, Sekotong, West Lombok Regency. A total of 14 bacterial isolates were successfully obtained and characterized based on morphological, physiological, and biochemical properties. All isolates produced IAA qualitatively and quantitatively (19.85–33.71 ppm) with isolate KT1 having the highest production (33.71 ppm). Qualitative phosphate solubilization test showed that 12 isolates were able to form a clear zone, while quantitatively it ranged from 7.86 to 16.18 ppm with isolate K8 having the highest value (16.18 ppm). Selected isolates KT1 (the highest IAA producer), K8 (the highest phosphate solubilizer), and K5 (both with high abilities) were tested for their effect on mung bean germination. Inoculation had a significant effect on plant height, root length, and dry weight (p<0.05). These results indicate that S. portulacastrum rhizosphere bacteria have the potential to be an environmentally friendly biofertilizer for plants in high-salinity soils.
