Abstract

Amed Waters, Bali, is one area that utilizes coral reefs in economic development. However, climate change, human activities and other factors have threatened the condition of coral reefs in Amed Waters. This study aims to determine the condition and social and economic potential of coral reefs and examine the appropriate blue economy strategy in maintaining the balance of coral reefs in Amed Waters, Bali. This research was conducted in September-November 2024. This research used direct field data collection methods such as Underwater Photo Transect (UPT), interviews and the Analytical Hierarchy Process (AHP). Based on the percentage of coral cover and the interviews' results, the results showed that coral reefs in Amed Waters can be classified as poorly damaged, so conservation efforts and sustainable management are needed to maintain the balance of coral reefs. Coral reefs have social and economic potential in the fisheries sector, with a fishing group of 19 people and marine tourism in the form of diving and snorkelling. The main focus of community economic development is the tourism sector. The blue economy strategy that can be applied in the conservation of coral reefs in Amed Waters, Bali, focuses on environmental aspects of coral reef health, economic aspects of increasing community income, and social aspects of community participation

Abstract

This study aims to determine the effect of a reverse biofloc system on the water quality, growth, and survival of red tilapia (Oreochromis niloticus). The research method is experimental with a completely randomized design (CRD). The containers used were 13 buckets with a capacity of 100 L, with one control and three treatments, each repeated four times. Each container was filled with 10 red tilapia fish. Treatments included probiotics with doses of 5 mL, 10 mL, and 15 mL. The results showed that the treatment with 15 mL probiotics produced the highest fish weight growth, with an average of 558.75 g and an average length growth of 9.1 cm. Analysis of variance (ANOVA) showed significant differences in fish weight and length growth, indicating that probiotic concentration influenced fish growth. All treatments' survival rates (SR) reached 100%, indicating that the inverted biofloc system can maintain optimal environmental conditions. Water quality in the reverse biofloc system did not significantly affect fish growth, so other factors, such as microorganism density and nutrient availability, played a role. This study concludes that the reverse biofloc system with the addition of 15 mL probiotics provides the best results in increasing the growth of red tilapia without affecting its survival.

Abstract

This research aims to determine the form of analysis, as well as determine the obstacles and constraints in implementing the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number: PERMEN-KP No. 210 of 2023 if guided by PERMEN-KP No. 58 of 2020 concerning capture fisheries businesses. In scientific research using a qualitative approach with an interpretative normative paradigm, the available theories used for research are constructed as an imperfect building, and this research is descriptive. In implementing the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number: PERMEN-KP No. 210 of 2023 concerning Limited Protection of Terubuk Fish (Tenualosa macrura) has not been implemented in the socialization, sea patrol and monitoring activities carried out by the Government, Indonesian National Army, Police and community monitoring groups. If PERMEN-KP No. 210 of 2023 is guided by PERMEN-KP No. 58 of 2020 concerning capture fisheries businesses, there will be discrepancies between the rules made and the rules applied in the field. The effectiveness of the implementation of the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia on the availability of fish resources legally and seen from fishermen's catches has increased and is quite effective, but it is not yet significant because sanctions for violations have not been realized and the obstacles and obstacles to the implementation of the Decree when referring to PERMEN-KP No. 58 of 2020 should not be needed. Fishermen who have small boats (< 5 gross tonnage) are allowed to catch terubuk (Tenualosa macrura) in conservation areas following PERMEN – KP No. 58 of 2020.

Abstract

This study aims to identify and analyze leading commodities in the aquaculture sector of Riau Province, using the Location Quotient (LQ), Shift Share, and Klassen Typology approaches. The analysis was conducted on aquaculture production data from 2019 to 2023 to identify commodities with the greatest potential and optimal contribution to the regional economy. The results show that the leading commodities in Riau Province are pangas catfish (Pangasianodon hypophthalmus) and catfish (Clarias gariepinus), both of which have an LQ value greater than 1, indicating that they are basic commodities with high competitiveness at the provincial level. Meanwhile, commodities such as carp (Cyprinus carpio L), Nile tilapia (Oreochromis niloticus), giant goramy (Osphronemus goramy), vaname shrimp (Litopenaeus vannamei), and milkfish (Chanos chanos), despite production fluctuations, still require more efficient management to improve their competitiveness. Based on the shift-share analysis, catfish and tilapia contribute positively and significantly to the growth of the aquaculture sector in Riau Province. Furthermore, the Klassen Typology analysis shows that pangas catfish and catfish fall into the "Advancing and Growing Rapidly" quadrant, while other commodities are in the "Potential or Rapidly Developing" quadrant. This study concludes that the aquaculture sector in Riau Province has great potential for development, particularly for catfish and tilapia, which can be strengthened through improvements in infrastructure, aquaculture technology, and commodity diversification to reduce production fluctuations. Improvement of infrastructure, aquaculture technology, commodity diversification, and farmer training can enhance productivity, quality, and market competitiveness both domestically and internationally in a sustainable manner

Abstract

The gourami (Osphronemus gouramy) cultivation faces challenges in terms of relatively slow growth. Lemna sp. plants can be a natural food for gourami and improve water quality to support gourami cultivation. However, Lemna sp. plants require NPK elements that can come from POC formulations from banana peel waste and catfish offal. This study aims to determine the effect of POC formulations from banana peel waste and catfish offal on Lemna sp biomass and to determine the best dose of POC formulations from banana peel waste and catfish offal on Lemna sp and goramy cultivation media. The research was conducted from August to November 2024 at the Hatchery and Environmental Quality Laboratory of Aquaculture, Faculty of Fisheries and Marine Sciences, Universitas Riau. The experimental study used a completely randomised design (CRD) with four treatments and three replicates. The treatments used were P0 (as control), P1: 1.625 mL/L, P2: 2.625 mL/L, and P3: 3.625 mL/L. The results showed that POC formulations from banana peel waste and catfish offal affected Lemna sp.'s biomass and goramy's growth. With treatment P1 (1.625 mL/L), the best dose was in Lemna sp. cultivation media and gourami (with treatment P1 (1.625 mL/L). Treatment P1(1,625 mL/L) is the best dose on the biomass of Lemna sp, which amounted to 767.47 g/m2, and the specific growth rate of Lemna sp. plants of 6.17%/day

Abstract

This research examines the influence of the Indian Ocean Dipole (IOD) and El Niño–Southern Oscillation (ENSO) on sea surface temperature (SST) and rainfall variability in the coastal waters of West Sumatra over the period 2014–2024. The analysis draws on the Dipole Mode Index (DMI), Niño 3.4 index, SST, and rainfall data, processed using MathWorks and Excel. Regression analysis between field and satellite-derived SST data showed a strong correlation (R² = 0.936), confirming the reliability of satellite data for this study. Findings reveal that positive IOD and El Niño events are generally associated with cooler SSTs and reduced rainfall. In contrast, negative IOD and La Niña phases correspond to warmer SSTs and increased rainfall. The IOD appears to exert a more pronounced influence on SST variability than ENSO. Notably, the combined occurrence of a positive IOD and El Niño amplifies the decline in SST and rainfall. At the same time, the combination of a negative IOD and La Niña enhances increases in these variables. These results highlight the significant role of large-scale climate mode in shaping regional oceanographic and atmospheric conditions in the West Sumatra region.

Abstract

This study aims to identify the types and abundance of phytoplankton at different depths and research stations in the coastal waters of Teluk Makmur Village, Dumai City, Riau Province. Samples were taken from three different locations, namely estuary areas, tourist areas, and areas far from settlements. The number of phytoplankton samples from the three stations at three depths was 27 samples. Water quality parameters such as temperature, salinity, pH, DO, TSS, nitrate and phosphate were measured to determine the condition of the aquatic environment and the effect on phytoplankton growth. Phytoplankton were analyzed using a microscope and identified using a phytoplankton identification book. The results showed that 27 species of marine phytoplankton were found in the Bacillariophyceae, Dinophyceae, Cryptophyceae, and Conjugatophyceae classes. The most common phytoplankton found came from the Bacillariophyceae class. The highest abundance of phytoplankton between depths was obtained from a depth of 3 m, namely 368,558.0441 ind/L, while the highest abundance of phytoplankton between stations was obtained from station III, namely 360,000.452 ind/L. The abundance of phytoplankton between depths and between stations showed no significant difference (p>0.05).
