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.</p> Fadli Fadli Fadhlin Akbar Atsiqah Tapaul Rozi Lilik Hidayati Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-30 2025-06-30 11 2 277 284 10.29303/jstl.v11i2.877 Kajian Kelayakan Usahatani Jamur Tiram Putih (Pleurotus ostreatus) (Studi Kasus Pada UMKM Agro Jamur Lombok Kecamatan Gunungsari Kecamatan Lombok Barat) https://jstl.unram.ac.id/index.php/jstl/article/view/876 <p>White oyster mushrooms are one of the alternative foods that can be produced by farmers to meet the food needs of the community. The purpose of this study was (a) to determine the costs incurred by farmers in white oyster mushroom farming activities, and (b) to determine the feasibility of white oyster mushroom farming in Lombok Agro Mushroom UMKM. This study uses a descriptive method, where data sources include primary data and secondary data. The number of respondents in this study was 3 people consisting of business owners and employees. The analysis tools in this study used the R / C Ratio and B / C Ratio. The results showed that the total cost incurred in this farming business was IDR 2,633,763, while the income obtained was IDR 6,000,000 and income was IDR 3,366,237. This white oyster mushroom farming business is feasible to run because the R / C Ratio value&gt; 1 and the B / C Ratio value&gt; 0 were obtained. The R / C Ratio value obtained in this white oyster mushroom farming business was 2.28 and the B / C Ratio value was 1.28.</p> Fadli Fadli Aeko Fria Utama FR Lilik Hidayati Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-30 2025-06-30 11 2 285 294 10.29303/jstl.v11i2.876 Studi Karakteristik Pohon Bertengger Celepuk Rinjani (Otus jolandae) di Desa Wisata Jeruk Manis, Lombok Timur, Nusa Tenggara Barat https://jstl.unram.ac.id/index.php/jstl/article/view/875 <p>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</p> Ahmad Jupri Isrowati Isrowati Komang Ratna Aprilia Sukraeni Ahmad Sadam Khazimi Tri Rahmi Fitri Alda Lilik Hidayati Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-30 2025-06-30 11 2 268 276 10.29303/jstl.v11i2.875 Karakteristik Habitat Pohon Pakan dan Populasi Lutung di Wisata Jeruk Manis, Resort Kembang Kuning, TNGR Sebagai Upaya Konservasi https://jstl.unram.ac.id/index.php/jstl/article/view/874 <p>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.

Indonesia, as the largest archipelagic country in the world, is home to six of the world’s seven sea turtle species, making it a globally significant habitat for the sea turtle life cycle. The Gili Matra Marine Protected Area, encompassing the three islands of Gili Trawangan, Gili Meno, and Gili Air, is one of the strategic regions with high potential for sea turtle conservation. This study aims to document and analyze the spatial distribution and habitat use of green turtles (<em>Chelonia mydas</em>) and hawksbill turtles (<em>Eretmochelys imbricata</em>) in the Gili Matra Marine Protected Area. Data collection was carried out during the period of September to October 2024, adjusted to weather conditions and water visibility. The method used was the Underwater Turtle Visual Census Methodology. The composition of sea turtle species and habitat characteristics were analyzed using descriptive analysis to summarize the patterns of species presence, habitat types, and environmental conditions observed during the survey. The findings indicate that the area supports both species, with sea turtles observed at various depths (9–16 meters) across multiple dive sites. The predominance of female individuals and the variation in species presence across sites suggest species specific habitat preferences and potential influences of environmental conditions. Both sea turtle was mostly observed in locations associated with coral reef structures.<strong>&nbsp;</strong></p> Wiwid Andriyani Lestariningsih Mahardika Rizqi Himawan Ibadur Rahman Gonzalo Araujo Cakra Adiwijaya Muhammad Hafidz Ibnu Khaldun Himaya Kartika Cahaya Dita Hikmatul Alam Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-30 2025-06-30 11 2 317 325 10.29303/jstl.v11i2.869
