Ecotourism very support for conservation. Ecotourism may assist with preservation of natural resources and ecotourism functions in comparison to other alternatives, such as mass tourism. This study aims to analyze the sustainability status of ecotourism management for preserving natural resources and ecosystem functions. This study is a survey on ecotourism destinations Clungup Mangrove Conservation (CMC). To analyze the level of sustainability, 9 dimensions were analyzed based on theoretical and empirical studies. The dimensions consisted of (1) conservation, (2) participation, (3) recreation and education, (4) economy, (5) control, (6) government, (7) ecotourism center, (8) academics/researchers, and (9) social media. This study employed quantitative analysis using Rapfish application with Multi-Dimensional Scaling (MDS) to assess the status and sustainability index of marine tourism management (CMC). The result revealed that the sustainability status of marine ecotourism management in CMC was categorized as “highly sustainable”. The highest value was the conservation dimension and the lowest value was in the government dimension. Therefore, government support for improving the role of ecotourism regarding preservation of natural resources and ecosystem functions is required. The government can give its support through implementing regulations, facilitating ecotourism management, designing public policy for ecotourism, and planning government policies that benefit the development of ecotourism.

Mangroves that grow in coastal areas have ecological and economic values. Research on the behavior of a mangrove ecotourism system is needed as a basis for management to provide sustainable benefits. This study aimed to describe the conceptualization of a mangrove ecotourism system, formulate a mangrove ecotourism model and formulate a scenario for Kampung Blekok mangrove ecotourism in Situbondo Regency. This study used a quantitative analysis with a dynamic system approach to see the behavior of the ecotourism system on the economic and ecological dimensions. The research results on the conceptualization of the ecotourism system with causal loop diagrams showed that the economic subsystem was composed of response variables in the form of ecotourism management income and community business income in ecotourism areas and gross regional domestic product. Meanwhile, the ecological subsystem consisted of response variables in mangroves’ death, planting, and rehabilitation. Model formulation with stock-flow diagrams demonstrated the relationship between response variables to explain the system. In the economic subsystem, the variable of community business acceptance had the highest sensitivity that could affect ecotourism income. While in the ecological subsystem, the highest sensitivity was on the variable of mangrove planting, which could affect the density of mangroves. The combination of economic subsystem scenarios optimized tourist visits and streamlined spending. The combination of ecological subsystem scenarios that became the priority was the addition of mangrove seedlings and controlling pests that caused the death of mangrove seedlings. Stakeholders are expected to synergize with each other in managing activities in ecotourism. Apart from exploiting their economic potential, the community and the private sector are also expected to participate in maintaining compliance with regulations to preserve mangroves. The government should monitor and enforce regulations related to ecotourism and support the development of mangrove ecotourism so that its benefits are sustainable.

Bee Jay Bakau Resort (BJBR) is one of the main tourist destinations in Probolinggo City that utilizes the mangrove ecosystem. The study aims to analyze the advantages position mapping of BJBR. The study uses correlational approach with accidental sampling of 70 respondents. Data were analyzed by using exploratory factor analysis (EFA) and correspondence analysis (CA) with 16 attributes. This study assessed three mangrove ecotourism sites in East Java. The main factors that influence tourists visiting BJBR are tourist attractions, prices, tourism completeness and safety, mangrove preservation, as well as service friendliness. BJBR has tourism advantages in the form of complete facilities and completeness of its attractions. Meanwhile, the advantages of Wonorejo Surabaya mangrove ecotourism are among others: the availability of education related to mangroves and the cleanliness of the facilities. On the other side, The Clungup Mangrove Conservation Malang has the advantages in the form of mangrove conservation, tourism beauty, tourism memories, and tourism safety. BJBR managers need to improve the sustainability of the mangrove forest ecosystem and educational facilities regarding the benefits of mangroves in order to have a positive impact on tourists.

This study objectives to analyze the estimated development of the production of the fish catches, analyze the factors which affect on the production amount, and to analyze the base or non bases are on Malang Regency. The method used is quantitative and the type of secondary data from BPS and DKP with documentation collecting technique. Quantitative data analysis of this research are quadratic trend, multiple linear regression and LQ. The calculation shows that marine fisheries catches production has increased an average of 6.5%. Factors that affecting of the production increase are the number of fishing vessel and fishermen amount. While the average value of LQ during the last 5 years shows that Sumbermanjing Subdistrict is a base region so it has the opportunity to develop.

Pulau Kalimantan merupakan pulau terbesar kedua di Indonesia yang mempunyai lima provinsi dengan 56 kabupaten/ kota. Produksi perikanan khususnya ikan air tawar mencapai 249.393 ton. Tujuan penelitian ini adalah menganalisis komoditas unggulan dan kontibusi ikan air tawar dari Pulau Kalimantan. Jenis penelitian yang digunakan adalah library research dengan menggunakan data sekunder dari BPS tahun 2021. Analisis data dalam penelitian ini adalah Location Quotient dan kontribusi. Jenis komoditas utama ikan air tawar yang diproduksi adalah gurame, patin, lele, nila dan ikan mas. Komoditas ikan lele merupakan ikan yang menghasilkan nilai LQ lebih besar pada 37 lokasi dan mendominasi dari komoditas sejenis. Wilayah yang berpotensi untuk dilakukan pengembangan ikan lele adalah Kalimantan Utara dan Kalimantan Barat. Namun, secara keseluruhan komoditas air tawar yang memberikan kontribusi nilai produksi tertinggi adalah Kalimantan Tengah senilai Rp.2.091 milyar atau 5,71% dari nilai produksi sector perikanan pulau Kalimantan.Kata kunci: komoditas unggulan, ikan air tawar, produksi ikan, provinsi
