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

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

Abstract

Frozen boneless milkfish is an innovative processed fishery product with high economic value, but product quality must be maintained to ensure food safety and competitiveness in the market. This study aims to analyze the suitability of frozen boneless milkfish quality at XYZ SMEs using the Statistical Process Control (SPC) approach. The quality parameters observed include sensory tests (color, aroma, taste, and texture), microbiological tests in the form of Total Plate Count (TLC), and measurements of the core temperature of the fish. The study used two storage methods, namely freezer and cold storage, with three storage periods (7, 14, and 21 days) and each was carried out three times. The results showed that all samples met the sensory quality standard with a value of ≥7, the core temperature of the fish was in the range of ≤–18°C, and the TLC value was still below the maximum limit of SNI, which is ≤5×10⁵ colonies/g. However, the results of the SPC analysis using the X-chart and R-chart control charts showed several points outside the control limits, indicating that the production process was not yet fully statistically stable. This indicates that although product quality generally meets standards, variations in the production process still need to be controlled to maintain quality consistency between batches. Therefore, the implementation of continuous quality control and production process improvements are essential to improve process stability and product quality of frozen boneless milkfish.

Tilapia can be cultivated in various places such as ponds, reservoirs, rice fields, ponds, rivers and even in waters that have higher salt levels than brackish freshwater. Experimental research experiment design, factorial design (complete randomized design) The experiment carried out in this study was the use of blue light color with different times as many as 3 treatments each repeated 3 times: Treatment A = 10 watt blue light without time change Treatment B = 10 watt blue light with 4 hours Treatment C = 10 watt blue light with 6 hours. Statistical data analysis using the ANOVA test was carried out using the help of the SPSS 16.0 program. The analysis aimed to find out the influence of blue light colour on the behaviour and growth of tilapia seeds. Based on the results of the study, it can be concluded that, Treatment of different irradiation times (0 hours, 4 hours, and 6 hours) has a significant influence on the absolute weight growth of tilapia. Treatment with a 6-hour radiation time per day showed the best weight growth compared to other treatments.

Abstract

This study aims to analyze biomass and carbon absorption in mangrove leaves and roots, especially Rhizophora mucronata and Avicennia alba. Data collection was carried out using purposive sampling techniques at two different location points. The measurement of biomass, carbon absorption in mangrove leaves and roots begins by taking samples using scissors and saws on the three predetermined trees and then taking them to the laboratory for analysis. The results showed that the average value of biomass in Avicennia alba leaves was higher (42.69 grams) than that of Rhizophora mucronata leaves (34.66 grams). Meanwhile, the highest average value of root biomass was in the mangrove Rhizophora mucronata (127.86 grams) compared to the root biomass of Avicennia alba (89.43 grams). The highest average value of leaf organ carbon absorption was in the mangrove Rhizophora mucronata (11.21%) compared to the mangrove Avicennia alba (9.09%). Meanwhile, the highest average value of root carbon absorption was in the Avicennia alba mangrove (12.17%) compared to the root carbon absorption of Rhizophora mucronata (10.85%). The results of the T-test showed that the carbon uptake in Rhizophora mucronata leaves differed significantly at 0.031 (<0.05) which means that Rhizophora mucronata leaves absorbed more carbon than Avicennia alba leaves, while others did not differ significantly (>0.05). The measured water quality parameters including temperature, pH, and salinity show that all water quality parameters are within the range of quality standards according to PP RI no. 21 of 2022 for marine life, except for the temperature at station 1 of the Rhizophora mucronata mangrove (Station 1: temperature 25.66 °C; pH 7.12; salinity 27.33 ppt and station 2: temperature 29.4 °C; pH 7.25; salinity 25.16 ppt.

Abstract

This study aimed to analyze the distribution of chlorophyll-a concentration and determine the water productivity status in Barrang Caddi Island, Makassar, Indonesia. Chlorophyll-a is widely recognized as an important indicator of phytoplankton abundance and primary productivity in marine ecosystems. The study was conducted in May 2025 using two approaches, namely direct measurements through spectrophotometric analysis and remote sensing analysis based on Aqua MODIS satellite imagery processed using SeaDAS software. Water samples were collected from three sampling stations, while satellite observations were performed weekly throughout the study period. The accuracy of satellite-derived chlorophyll-a data was evaluated using the Root Mean Square Error (RMSE) method. Spectrophotometric analysis revealed that chlorophyll-a was detected only at Station 2, with a concentration of 0.068 mg m⁻³, whereas concentrations at Stations 1 and 3 were below the detection limit. In contrast, remote sensing analysis showed higher chlorophyll-a concentrations ranging from 0.740 to 1.244 mg m⁻³ during the observation period. These values indicate that the waters surrounding Barrang Caddi Island were generally characterized by moderate productivity and classified as mesotrophic. The RMSE value between laboratory measurements and satellite-derived estimates was 1.176 mg m⁻³, indicating a considerable discrepancy between the two methods. Despite this difference, remote sensing proved effective for describing the spatial and temporal distribution of chlorophyll-a over a wide area. The findings suggest that Barrang Caddi Island waters possess moderate biological productivity and have the potential to support sustainable fisheries and other marine resource management activities
