Abstract

Paus sperma (Physeter macrocephalus) merupakan salah satu biota laut yang dilindungi di Indonesia. Identifikasi molekuler paus sperma dari perairan Laut Sawu (Nusa Tenggara Timur, Indonesia) telah dilakukan menggunakan gen 16S rRNA. Penelitian ini bertujuan untuk menvalidasi spesies paus sperma (Physeter macrocephalus) di Indonesia menggunakan gen cytochrome oxidasesubunit I (COI) parsial. Spesimen yang digunakan merupakan spesimen jaringan dari koleksi laboratorium yang diambil dari perairan Laut Sawu tahun 2014. Ketiga spesimen tervalidasi sebagai Physeter microcephalus dengan kemiripan sebesar 100%. Komposisi basa didominasi oleh basa timin (31,7-31,8%) dengan GC konten sebesar 42,7–42,8%. Jarak genetik pada spesies yang sama didapatkan nilai sebesar 0,0015, sedangkan jarak genetik tertinggi dengan spesies Orcaella brevirostris sebesar 0,2128. Identifikasi molekuler menggunakan gen 16S rRNA dan COI telah menvalidasi spesies paus sperma (Physeter macrocephalus) di Indonesia, sehingga data genetik ini dapat digunakan sebagai dasar pengelolaan dan konservasi sumberdaya paus sperma.

Abstract

Seaweed cultivation is a major economic activity in Indonesia's coastal areas, but its sustainability challanged by complex socio-ecological interactions that are not fully captured by conventional sustainability assessment approaches. The Rapid Appraisal for Fisheries (Rapfish) method has been widely applied, but most studies still employ generic multidimensional attributes that do not explicitly reflect the principles of the Ecosystem Approach to Aquaculture (EAA). This study integrates EAA principles into the selection and grouping of Rapfish attributes to provide a holistic assessment of seaweed farming systems. This study aims to assess the multidimensional sustainability of Eucheuma cottonii cultivation in Sampolawa Bay, South Buton Regency. The analysis was conducted using the Multi-Dimensional Scaling (MDS) approach in the Rapfish tool across five sustainability dimensions: ecology, economy, society, technology, and institutions. The results showed that EAA integration enhances the comprehensive assessment framework, especially in the social and institutional dimensions. Overall, seaweed cultivation in Sampolawa Bay was categorized as moderately sustainable with an index value of 60.64. The social and ecological dimensions were the main pillars of sustainability, whereas the economic dimension was a limiting factor requiring attention. particularly regarding market accessibility and price stability to ensure the sustainability of seaweed cultivation in the future.

Abstract

Mariculture, or the cultivation of aquatic organisms, holds the potential of enhancing food security, income diversification, and overall economic sustainability. To ensure its growth in the long run, it has to be sustainable particularly from the perspective of local communities, economically profitable, and environmentally friendly. The aim of this paper is to assess the acceptability for the feasibility of potential mariculture development in Mohéli, Comoros, a place with no existing mariculture activity, using Multi-Criteria Decision Analysis (MCDA), scenario planning, and stakeholder preference elicitation. Interviews and focus group discussions were conducted with key stakeholders, including local fishers, lawmakers, and environmental experts, to collect data. The results of the study show that economic gain is the main driving force behind the support for mariculture in the assessed communities, but acceptability is also a function of environmental aspects. Of the many mariculture options, seaweed farming was found to be the most recommendable because of its short harvest period, minimal impact on the environment, and low costs. The study shows that there is a need for specific awareness campaigns, collaborative decision making, and strategically changing management measures to solve ecological and socio-economic problems. The present research can be helpful in this regard as it suggests a method of integrating community interests with scientific decision-making tools to develop a roadmap for the growth of sustainable mariculture while ensuring that there is harmony between social, environmental and economic aspects of development in coastal areas.

Abstract

In this study, as a data-poor fish stock assessment method CMSY was used to assess the current stock status of the Sword Prawn in Samboja Waters. A total of 13 years catch data (from 2012 to 2024) was used in the analysing process of study. Estimated CMSY model parameters with confidence intervals are as folloe: r=0.47 (0.29-0.7) year-1, k=14.9 (10.1-22) ton, MSY=1.75 (1.23-2.36) ton, B2024=4.2 (0.43-5.89) ton, BMSY=7.45 (5.05-11) ton, F2024=0.28 (0.2-2.71) year-1, FMSY=0.23 (0.14-0.38) year-1, B2024/BMSY=0.56 (0.05-0.79) and F2024/FMSY=1.18 (0.84-11.4). Our study has found that sword prawn population in Samboja waters has been decline due to overfishing since 2017. Until now, regulations regarding catch quotas have not been established or implemented. Therefore, it is recommended to create regulations related to catch quotas based on research findings and reduce fishing mortality to maintain populations and prevent further biomass decline.

Abstract

This study aims to assess the distribution of Cherax quadricarinatus based on depth and evaluate its invasiveness using a risk assessment in Lake Laut Tawar, Central Aceh. The study was conducted at five stations representing various lake activities: Station 1 (One-One), Station 2 (Bewang), Station 3 (Gegarang), Station 4 (Mendale), and Station 5 (Dedalu). The methodology involved direct observation in the field followed by laboratory analysis. The results showed that 284 individuals were caught, consisting of 138 females and 146 males, with carapace lengths ranging from 20 to 76 mm. No consistent distribution of male and female carapace lengths was observed across all stations. The abundance of Cherax quadricarinatus in Lake Laut Tawar was classified as very abundant (20%) at One-One and Bewang stations, both at a depth of 5 meters. In conclusion, Cherax quadricarinatus significantly dominates the lake ecosystem, as indicated by its relative abundance at different depths across the study sites. This species also shows a high potential for invasion in freshwater lakes, highlighting the need for effective management strategies.Keywords:Cherax quadricarinatusInvasive spesiesLake Laut Tawar, Aceh

Abstract

Literacy culture is a strategic condition for implementing Merdeka Belajar because independent learning requires students who can read critically, select information ethically, reflect on experience, and communicate ideas responsibly. Yet school literacy programs often remain procedural when planning, role distribution, implementation, and supervision are not managed participatively. This study analyzes how participatory management shapes the development of an independent-learning literacy culture in senior high schools in the Bangka Belitung Islands. This study employed qualitative field research in senior high schools that had implemented the Merdeka Belajar curriculum. Data were collected for 12 months through observation, semi-structured interviews, and documentation involving principals, curriculum leaders, infrastructure leaders, librarians, homeroom teachers, subject teachers, and students. Data were analyzed through data condensation, data display, conclusion drawing, and verification, while credibility was strengthened through source and technique triangulation. The findings show four interconnected management functions. Planning emerged through teacher initiatives and principal facilitation, producing a literacy team, 15-minute reading habituation, reading-corner planning, student literacy ambassadors, and library-based resource development. Organizing distributed responsibilities among the principal, literacy team, curriculum unit, library, homeroom teachers, and students. Implementation established reading routines, journals, library visits, and literacy competitions but was constrained by limited book collections, underused reading corners, and uneven library accreditation. Supervision combined direct monitoring, reading journals, peer reminders, and semester evaluation. The study contributes a participatory literacy management model aligned with Al-Tadzkiyyah's scope on Islamic educational leadership, management, pedagogical innovation, contextual dynamics, and SDG 4-oriented quality education.
