Abstract

Microplastics are the result of degradation and fragmentation originating from plastics with a size of <5 mm. Currently, many people use broiler chicken intestines which are possibly contaminated by microplastics as food for pomfret (Colossoma macropomum) in floating net cages (KJA). The purpose of this study was to determine the number and type of microplastics present in the intestines of broiler chickens and the digestive tract of pomfret cages (C. macropomum) and to see the correlation level of the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed using intestines. broiler chicken. The method used in this study was purposive sampling for the sampling of pomfret cages (C. macropomum). A sampling of broiler chicken intestines was carried out at random from KJA fish cultivators in Teluk Kenidai Village. The results obtained were microplastics of film type, fiber, and fragments found in the intestines of broiler chickens and the digestive tract of pomfret (C. macropomum). The number of microplastics found in broiler chicken intestines was 322 film particles, 112 fiber particles, and 52 fragment particles. While in the digestive tract of pomfret (C. macropomum) 343 are film particles, 203 fiber particles, and 63 fragment particles. The relationship between the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed with broiler chicken intestines has a very strong relationship with a correlation value of 0.952.

Abstract

Spirulina platensis is a highly nutritious cyanobacterial microalga. This microalga is rich in protein, vitamins, minerals and antioxidants. The use of media and cultivation methods that are not appropriate can affect the nutritional content of this microalgae. This study aims to evaluate the effect of urea on growth, biomass production, nutrient content and pigments of S. platensis on an outdoor scale. Technical media such as urea are used instead of nitrate in standard media (zarrouk). This study used four treatments with three replications. The treatments used were different doses of urea, namely 0.1 g/L, 0.4 g/L, 0.7 g/L, and 1 g/L. The results showed that the use of urea affected the growth and nutritional content of S. platensis. The use 0.4 g/L urea producued comparable results than that of nitrate as nitrogen source. However, phycocyanin content was still lower than nitrate-based media. Inconclusion that urea was potential alterative nitrogen source for spirulina cultivation.

Abstract

Hand line is a type of fishing gear that is active and environmentally friendly and is often used by traditional fishermen to catch fish with high economic value. The right bait is one of the factors for maximizing catches. Fishermen around the village of Fiditan, Jellyfish Island, Kota Tual generally use various kinds of bait, such as Momar fish (Decapterus sp), Sikuda fish (Letrinus lenca) and Nipah worms (Namalycastis). This research was held in November – December 2022. The objectives are: to know the composition of hand line catches with different baits and to determine the type of bait that gives the most catches. This research is expected to provide information and knowledge to fishermen about hand line fishing gear units using different baits. Data analysis used a randomized block design, with baits used were Momar fish, Sikuda fish and Nipah worms. During the study, a total of 346 fish were caught consisting of Sikuda fish (Letrinus lenca) with a total of 294 fish (85.5%), followed by Gora fish (Lutjanus carponotatus) 25 individuals (7.33%), Sand-sand fish ( Taeniura ymma) 20 individuals (1.16%) and the smallest catch was Gace fish (Lutjanus malabericus) with a total of 1 fish (0.29%). The results of the analysis of variance showed that the Fcount for the treatment (8.66) was greater than the Ftable (0.05); 14:2) (88.5) so statistically H0. This means that the difference in the use of bait has a very significant effect at the level of ά = 0.05 on the catch. The BNT test results also showed differences in the value of each bait so that it was concluded that the three baits used by fishermen had a significant difference in the catch obtained with Sikuda bait with the highest yield, followed by Nipah worm and Momar fish bait.

Abstract

Coral reefs are ecosystems in the sea formed by lime-producing marine biota, especially stony corals and calcareous algae, along with other biota that live on the ocean floor. Coral reefs are ecosystems that play an important role in coastal areas but are vulnerable to internal and external changes. The purpose of this study was to calculate the percentage of coral reef cover and assess the condition of coral reefs on the Kapoposang Island. Coral Point Count with Excel Extension (CPCE) was used to analyze coral reef data. The data used were photos of coral reefs taken using the Underwater Photo Transect (UPT) method from six observation stations scattered around Kapoposang Island. Each processed photo contained 30 randomly selected points. The results of the assessment of the condition of coral reef health at five stations showed that station 1 (one) 35.62% was in moderate condition, station 2 (two) 43% was in moderate condition, station 3 (three) 46.67% was in moderate condition, station 4 (four) 40.53% is in moderate condition, station 5 (five) 41.84% is in moderate condition and station 6 (six) 29.25% is in moderate condition. From the five data collection stations the condition of coral reefs on Kapoposang Island was in the moderate category with a percentage of 39.49%.

Abstract

Blackskin catfish (Clarias meladerma Bleeker, 1846) is one of the endemic freshwater fish that has economic value but this fish has not been cultivated, besides that the problem is that this fish still has slow growth and low survival in the larval stage. One approach that can be taken to increase growth and survival is by administering vitamin C through natural feed enrichment in the form of Daphnia sp., so the aim of this study was to evaluate the impact of giving Daphnia sp. enriched with vitamin C on the growth and survival of blackskin catfish larvae. The research method used was a Completely Randomized Design (CRD) with 4 treatments to wit Daphnia sp. enrichment. with a dose of vitamin C each of 0 mg/L, 150 mg/L, 200 mg/L and 250 mg/L and each treatment was repeated 3 times, for the enrichment process by immersing Daphnia sp. with vitamin C carried out for 3 hours. Rearing of the larvae was carried out in an aquarium with a volume of 10 L of water and a stocking rate of 2 fishes/L with an initial size of larvae 0.70 ± 0,00 cm. During rearing the larvae were fed 4 times a day. The results showed that the administration of Daphnia sp. enriched with vitamin C gave the best growth in the P3 treatment (250 mg/L), specifically the absolute length growth was 0.81 cm better than the control treatment, the absolute weight growth was 0.43 g better than the control treatment, the specific growth rate was 0.54% better than the control treatment and survival 18.4% better than the control treatment. (P<0.05). So based on this study, it was concluded that the enrichment of Daphnia sp. with vitamin C has a positive impact on the growth and survival of blackskin catfish larvae (Clarias meladerma Bleeker, 1846).

Abstract

The operation of the engine on a ship is supported by sufficient fuel. Fuel is converted into mechanical energy to drive engines on the ship, such as the main engine and auxiliary engines. The Phinisi Natural 001 ship is one of the tourist ships that operates tourist services in the Komodo National Park Tourism area, so to support these activities it is necessary to have appropriate fuel requirements. There is a lack of information about the fuel requirements on this ship, so an analysis was carried out on the fuel consumption needs of the main engine on the Phinisi Natural 001 ship. This is important to be able to predict and prepare for fuel needs during tourist trips. Descriptive methods were used to support this activity, namely interview procedures, direct observation, regression analysis, work analysis and T Test. Based on the results obtained, significant differences were found between calculated and observed fuel consumption results on the 2D1N journey (p<0, 05), but in the 3D2N trip no significant differences were found (p>0.05). From the calculation results, the average amount of fuel used in the 2D1N and 3D2N travel programs was 95.31 liters and 146.66 liters, while the observation results obtained were 113.33 liters and 136.67 liters. The differences in the results of calculations and observations are caused by internal and external factors such as blockages in the nozzle, the ship floating, shipping routes, and weather influences, such as currents and sea waves during the trip.

Abstract

Marine debris is widespread in oceans around the world, including in the most remote locations. Here, we conducted on the accumulation of macro debris on the Misool Island beach, an island ± 192 km away from the mainland of Sorong. The aim of the research is to examine compositions, densities, and accumulation rates of marine debris in two locations, namely Salafen and Waigama beaches at April-Mei 2023. The total amount of marine debris collected was 125 items during the survey conducted at two beaches with a total of 1.498 grams. The mean of densities marine debris is 0.12 ± 0.05 items/m2 and 1.49 ± 0.85 gr/m2 based on the weight. As much as 93% of the debris was marine debris categories plastics, followed by metals (3%), glass, and rubber as much as 2% respectively from a total of debris. The mean of debris accumulation rates showed the highest debris accumulations were found in Salafen beach (39.9 gr/days) than in Waigama beach (31.4 gr/days). Long-term monitoring is most important for more understanding of the path and temporal changes for the management of marine debris in the future.

Abstract

Heavy metal pollution and its hazards are global issues that need proper attention. Heavy metals are toxic to the environment and aquatic organisms. As a filter feeder, Kepah are able to absorb and accumulate heavy metal from the environment into their body. Kepah is edible bivalve that widely consumed because its potential nutritional value, so that the biotoxic effect in human are great concern. Peniti River has important roles for the coastal community, especially in Mempawah Regency. This area has been developed for various uses. These activities greatly influenced water condition and were considered as sources of pollution, including heavy metals. The aim of this study was to evaluate the Pb content in Kepah flesh, water, and sediment collected from the mangrove ecosystem area of Peniti Village. The sample collection and measurement of environmental parameters were carried out at two stations based on the presence of Kepah. The standard technique was used to quantify the Pb level in the samples. The analysis of Pb content was performed using an Atomic Absorption Spectrophotometer (AAS). The concentrations of Pb in the water and sediment samples were above the threshold. Meanwhile, the metal content of Pb in Kepah flesh was still below the maximum limit that had been determined. Therefore, Kepah from the mangrove ecosystem of Peniti Village, Mempawah Regency, were still good for consumption.
