Abstract

The recirculation system, in principle, is the reuse of water that has been removed from cultivation activities. Cachama (Colossoma macropomum) is a relatively high economic value fishery commodity. This study aimed to obtain the best filter dose for water quality on the survival of cachama. The experimental method used a completely randomized design with six permitted treatments and three replications. The treatment used was P0 (without filter) with P1 (100% charcoal filter), P2 (100% zeolite filter), P3 (50% charcoal and 50% zeolite filter), P4 (25% charcoal and 75% zeolite filter), and P5 (75% charcoal and 25% zeolite filter) the fish kept for 50 days. The results of this study showed that the best treatment was P4 (25% charcoal and 75% zeolite filter), which resulted in a recent weight growth of 6.12 g, static length growth of 4.86 cm, growth rate specific growth of 2.08%, survival of 100%, and food conversion ratio of 1.95. Providing 25% charcoal and 75% zeolite filters affects water quality, growth, and survival rate

Abstract

This study aims to determine the perceptions of local communities towards marine sand mining activities in the Kepulauan Riau Province. Considering the region's dominance, Kepulauan Riau has great potential for sand mining in terms of quality and quantity. The population dynamics and high development today encourage an increased need for sand. Therefore, sand mining businesses have become social, economic, and ecological. This research uses a descriptive qualitative approach with an interview method with 60 respondents. Multiple linear regression analysis was used to predict perceptions based on social, economic, and ecological variables. The results showed that social aspects (coefficient value of 0.809) strongly influenced the sustainability of mining activities compared to ecological aspects (0.271) and economic aspects (-0.045). This finding shows that if mining activities can create good social conditions in local communities, sand mining activities can continue. However, these social conditions are related to the ecological impacts caused by mining

Abstract

Oil pollution in the waters is one factor affecting the abundance of phytoplankton, especially the diatoms. The waters of Bengkalis Strait, Pangkalan Jambi Village, and Bengkalis Regency are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundant of planktonic diatoms, and explain the relationships between the total oil content and the abundant of planktonic diatoms carried out in the Bengkalis Strait, Pangkalan Jambi Village Bengkalis Regency, Riau Province. This research uses a survey method. Station 1 is near fish ponds and mangroves, station 2 is in the harbor where the fishing boats moor, station 3 is in wharf bridge and residential areas, and station 4 is in mangrove ecotourism. The result of the oil content analysis obtained an average value of 0.216 ppm. The highest oil content at station 2 is 0.5742 ppm, and the lowest at station 4 is 0.0775 ppm. The calculations of the abundance of planktonic diatoms ranged from 3,323.28 to 11,631.48 ind/L. The highest abundance at station 3 was 9,692.2 ind/L. The lowest abundance was at Station 2, which was 4,154.1 ind/L. Simple linear regression test results obtained equation Y = 6045.927572 + (3013.071268x). The coefficient of determination (R2)= 0.049 states that 4.9% of the abundance of planktonic diatoms is influenced by oil content, and other environmental factors influence the rest. The correlation coefficient (r) = 0.0223, so the relationship between total oil content and the abundance of planktonic diatoms is very weak

Abstract

he fisheries potential in Tanjung Medang Village is highly promising for development due to its predominantly coastal location. This research aims to identify the mackerel supply chain pattern in Tanjung Medang Village using the Food Supply Chain Network (FSCN) approach. The method used is a survey method. Data analysis uses supply chain pattern analysis with the FSCN approach. The research results show that the mackerel supply chain pattern in Tanjung Medang Village has a supply chain structure consisting of primary and secondary members. Supply chain targets include the export market (Malaysia) and the local market (Tanjung Medang). The application of supply chain management includes bound and unbound partner relationships between supply chain actors, contractual agreements that occur informally, and transactions between supply chain actors using credit and prepayment systems. Supply chain business processes include collaborative planning that appears in each supply chain actor; the risks faced by each supply chain actor are different. The resources owned by the supply chain are by needs (physical resources, capital, technology, and human resources)

Abstract

Mangrove crab (Scylla serrata) catching activities generally use collapsible traps. Folding traps can be operated using bait and not using bait, but the catch is less effective if it does not use bait. The purpose of this study was to determine the effect of using different types of bait (fresh stingray, salted stingray, fresh eel, and salted eel) on the catch of Mangrove crab in Kampung Laut waters. The material of this research is the catch of mangrove crabs using fresh stingrays, salted stingrays, fresh eels, and salted eels as bait. The research method used is experimental fishing. The collected data includes environmental parameters, the number of catches, and the trap size. Data analysis used a Completely Randomized Design (CRD) and Duncan's follow-up test. The results showed that the different types of bait used affected the number of catches, catch weight, and catch size. This study concludes that the catch of mangrove crabs with salted stingray bait gets the most catches, namely 16 fish, and on salted eel bait gets 13 catches, while in fresh stingray bait treatment, it only gets seven catches and on fresh eel gets five catches.

Abstract

Research on tidal analysis based on seasons has been carried out in Lasolo Bay, Southeast Sulawesi, using secondary data, namely tidal data in 2021 in January representing the western season, April representing the transition season I, July representing the eastern season and October representing the transition season II. This study aims to determine the type of tides formed and the value of sea level elevation in each season at the research site. Tidal data processing uses the admiralty method, producing amplitudes and phase differences from 9 main harmonic components. The analysis results of the calculation of formzhal numbers show that the type of tides formed in Lasolo Bay is a mixed type of double daily inclined with a formzhal number value of 0.5618-0.7059. In addition, based on the calculation of sea level elevation, the maximum average sea level (MSL) occurs in the second transition season (October), which is 532 cm, and the western season (January) is 460 cm. For the other two seasons, the first transitional season (April) and the eastern season (July) have an average sea level of 101 cm and 130 cm
