This study aims to assess the condition of coral reefs based on benthic composition in the shallow waters of Tanjung, Senggigi Beach, West Lombok, West Nusa Tenggara. Data collection was carried out through diving using the Underwater Photo Transect (UPT) method by analyzing 50 quadrat photos taken along a 50-meter transect line, processed with the CPCe software. The analysis revealed that live coral (Coral) was the most dominant benthic component, with an average cover of 91.38% ± 13.72%, which falls under the "very good" category. Macroalgae and abiotic components such as sand and coral rubble were present but in very small proportions. The coral community was dominated by complex growth forms such as Acropora tabular, Acropora branching, Coral foliose, and Coral massive, which are known for their relatively fast growth and adaptability to clear water with stable substrates. These findings indicate that the reef ecosystem in the waters of Tanjung Senggigi is in very good condition and provide a scientific foundation for developing effective management and conservation strategies for the area.

Octopus is one of the fisheries products that has high economic value and stable demand, especially from the export market. This study aims to analyze the marketing strategy of octopus in Sekotong District, West Lombok Regency, using a descriptive approach through SWOT analysis and EFAS and IFAS matrices. Data were collected through observation, interviews, and distributing questionnaires to 30 respondents consisting of fishermen and collectors. The results of the study indicate that the marketing strategy of octopus still faces a number of challenges, such as the weak bargaining position of fishermen, limited post-harvest handling facilities, minimal access to promotion, and high dependence on middlemen. The SO (Strength-Opportunity) strategy is the most recommended strategy, especially by encouraging digital promotion and the formation of fishermen's institutions to expand market access.

The study entitled Characteristics of Food Tree Habitat and Langur Population in Jeruk Manis Tourism, Kembang Kuning Resort, TNGR aims to understand the role of habitat in the survival of the Javan langur (Trachypithecus auratus), an endangered primate species. The Javan langur functions as a natural seed disperser in the forest, and its presence is very important for the plant regeneration process. This study was conducted in November-December 2024 in Kembang Kuning Village, East Lombok, using the population census method and vegetation analysis. The research method includes collecting data on the langur population through the concentration method and vegetation analysis by creating sample plots measuring 20 x 20 m. The results showed that the langur population varied in various plots, with a higher proportion of adult individuals in some locations, indicating group stability. The data also showed that the bajur tree (Pterocarpus indicus) was the main food source with a high Importance Value Index (INP) value. This study provides insight into the composition and structure of vegetation in the langur habitat, as well as the importance of conserving this species in the face of threats from hunting and habitat loss. By understanding the characteristics of the habitat and distribution patterns of the langur population
