Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jenis wadah budidaya berupa keranjang bambu dan keranjang plastik terhadap pertumbuhan anggur laut (Caulerpa racemosa) yang dibudidayakan menggunakan sistem longline dalam bak terkontrol. Penelitian dilakukan selama 35 hari di SMK Negeri 1 Maluku Tenggara, menggunakan metode eksperimental dengan rancangan acak. Parameter utama yang diamati adalah pertumbuhan berat thalus dan pertumbuhan berat mutlak. Hasil penelitian menunjukkan bahwa penggunaan wadah keranjang bambu menghasilkan pertumbuhan thalus yang lebih tinggi dibandingkan keranjang plastik dan kontrol. Analisis statistik menggunakan ANOVA menunjukkan perbedaan yang signifikan (p<0,05) antar perlakuan. Pertumbuhan yang lebih baik pada keranjang bambu diduga disebabkan oleh karakteristik fisik bambu yang menyerupai substrat alami, seperti permukaan kasar yang mendukung perlekatan rizoid. Faktor lingkungan seperti kedalaman, intensitas cahaya, dan kualitas air (suhu, pH, salinitas, dan oksigen terlarut) juga berada pada kisaran optimal untuk pertumbuhan C. racemosa. Hasil ini merekomendasikan penggunaan keranjang bambu sebagai media efektif dalam budidaya anggur laut secara terkontrol

Abstract

This study aims to analyze the biological aspects of the kejen shark (Carcharinus falciformis) landed at the Paotere Fish Landing Base (PPI), Makassar, including its size structure and growth pattern as a basis for information on sustainable resource management. The study was conducted in January–March 2025 using a field survey method. Kejen shark samples were obtained from fishermen's catches landed at the Paotere PPI. Each individual caught was measured for total length (cm) and body weight (kg). Data were analyzed to determine the size distribution and length–weight relationship using regression analysis. The results showed that the total length of male kejen sharks ranged from 65–145 cmTL and females 65–155 cmTL, with body weights of 1–13 kg and 1–25 kg, respectively. The length–weight relationship produced a regression equation with a coefficient of determination (R²) of 0.9061 and a growth coefficient (b) of 3.3188, indicating a positive allometric growth pattern. The size structure of the fish caught indicates that the catch encompasses a wide range of sizes, including sexually immature individuals. This situation has the potential to reduce the wild population of the kingfisher, given its relatively slow growth and reproduction rates, necessitating more selective and sustainable fishing management.

Abstract

This study aims to analyze the financial aspects of mantis shrimp (Lysiosquillina maculata Fabricus, 1793) fishing conducted by local fishermen and landed on Tanakeke Island. Mantis shrimp is a marine species with high economic value but has not been optimally utilized. The research was conducted over a two-month period using a quantitative method and purposive sampling technique, involving surveys of thirty fishermen. Financial economic data were obtained through interviews and used to analyze costs, revenues, and profits. The results of the study show that economically, mantis shrimp fishing provides an average annual income of IDR 211,680,000, with a net profit of IDR 98,240,000, an R/C ratio of 2, and a payback period of three years. This study indicates that the community of Tanakeke Island can experience significant economic benefits from mantis shrimp fishing. However, the presence of shrimp being caught before reaching a viable catch size

Abstract

Nickel mining plays a strategic role in supporting the national economy, particularly for the metal and renewable energy industries. However, mining activities also generate significant environmental impacts, especially land degradation and the decline of aquatic resource quality due to increased sedimentation, alterations in the physical and chemical properties of soil and water, and the introduction of heavy metals into aquatic systems. These conditions directly disrupt aquatic ecosystems and reduce biodiversity. This article aims to review rehabilitation and conservation strategies for aquatic resources in post-nickel mining areas through a literature review approach. The study employed a descriptive qualitative method by analyzing relevant national and international scientific publications focusing on land reclamation, revegetation, water quality management, and post-mining aquatic ecosystem restoration. The review results indicate that effective rehabilitation of aquatic resources requires an integrated approach, including land reclamation to stabilize soil conditions, revegetation using adaptive plant species to improve soil fertility and control erosion, and water quality management through sedimentation ponds, constructed wetlands, and riparian vegetation. The implementation of these strategies has been shown to reduce sediment and heavy metal loads, improve water quality, and support the recovery of aquatic ecological functions. Furthermore, community involvement and sustainable management practices are essential to ensure long-term rehabilitation success. With well-planned and sustainable rehabilitation efforts, post-nickel mining areas have the potential to be restored into healthy and productive aquatic ecosystems that provide ecological as well as socio-economic benefits for surrounding communities

Abstract

Urban activities are one of the main factors that put significant pressure on river ecosystems through the disposal of domestic waste, industrial waste, and surface runoff that carry various types of pollutants, along with population growth, increased economic activity, and uncontrolled land-use changes. These conditions have an impact on the decline in water quality which is characterized by an increase in the load of organic matter, nutrients, and harmful substances, thereby triggering the degradation of river habitats in the form of excessive sedimentation, damage to riparian vegetation, and changes in the physical structure of river channels, which ultimately lead to a decrease in aquatic biodiversity, both in terms of number and species composition. Many aquatic organisms, such as fish and macrozoobentos, are becoming increasingly vulnerable to pollution and habitat loss, resulting in population declines and even local extinctions. Based on these conditions, this article aims to examine the concept of conservation and rehabilitation of river aquatic resources affected by urban waste through a national literature review approach. The method used is a literature study of Indonesian scientific journals, reference books, and official government documents related to environmental and water resources management. The results of the study show that urban river conservation and rehabilitation efforts require an integrated approach that includes pollution control through effective waste management, restoration of river and riparian habitats, and sustainable management of watersheds, supported by strong environmental policies, consistent law enforcement, and active community participation to ensure the sustainability of the ecological function of rivers
