Abstract

Kepulauan seribu archipelago is home to Kelapa Dua Island, a potential marine tourism destination and habitat for diverse marine life. The survival of marine biota hinges on suitable physical and chemical water parameters, encompassing temperature, pH, salinity, and dissolved oxygen (DO). This study aims to evaluate water quality and litter distribution on Kelapa Dua Island within Kepualauan Seribu National Park. Results reveal that the water quality largely aligns with established standards; however, specific points surpass limits, notably lower salinity at stasion 3 (26%o), and higher pH at station 2 (9.35). Despite meeting quality standards, the island's status as a populated area and tourist destination raises concerns about potential alterations to water quality. Furthermore, observations on litter distribution indicate a status categorized as B (0-4/m) and C (4-10/m), highlighting a relatively low level of litter presence. The interaction of human activities, both as inhabitants and visitors, may contribute to fluctuations in water quality. Understanding these dynamics is crucial for sustainable management, ensuring the preservation of Pulau Kelapa's ecological integrity as a cherished marine environment and tourist attraction. This study provides insights into the delicate balance between human interactions and environmental preservation in the context of Pulau Kelapa, Kepualauan Seribu.Keywords:Water qualityLitter DistributionKelapa Dua IslandKepulauan Seribu

Abstract

The tuna fishing industry significantly contributes to greenhouse gas (GHG) emissions primarily through fuel oil usage. This study investigates the environmental impact of tuna transportation, focusing on emissions from fishing vessels and vehicles. Carbon footprint calculations for fishing vessels utilize the IPCC, 2006 formula as referenced in KLH, 2012. Smaller purse seiners (10-20 GT) emit 2.88 kg CO2per trip per kilogram of tuna, while those (20-30 GT) in PPS Kutaraja emit 3.58 kg CO2. Larger purse seiners exhibit higher emission rates: 7.3 kg CO2 (20-30 GT), 9.9 kg CO2 (30-40 GT), 8.6 kg CO2 (40-50 GT), and 8.4 kg CO2 (50-60 GT) per trip per kilogram of tuna. Vehicle emissions for tuna transport vary, with the Honda Blade FI 125 emitting 0.00625 kg CO2, Supra X 125 emitting 0.00450 kg CO2, Viar Tiga Roda emitting 0.00458 kg CO2, Revo Fit emitting 0.0007 kg CO2, Jupiter emitting 0.00063 kg CO2, and Vega ZR Yamaha emitting 0.0006 kg CO2 per kilogram of tuna.Keywords:Carbon FootprintEmissionFsihing VesselsGreen TransportationsSupply ChainFishing Activties

Abstract

Pidie Jaya Regency is one of the districts that contributes to capture fisheries production in Aceh Province. Pidie Jaya Harbor is the Fish Landing Base (PPI) in Meureudu. As capture fisheries activities developed at PPI Meureudu, the local government began to pay attention to building several port facilities such as basic facilities, functional facilities and supporting facilities. Supporting facilities or supporting facilities are facilities that support fishing activities at the port, one of these facilities is an ice factory. The ice factory at PPI Meureudu belongs to the Aceh marine and fisheries service which was built in 2012. The Aceh Development Fund (ADF) built an ice factory with a production capacity of up to 30 tons/day at the Meureudu Fish Landing Base (PPI), through an environmentally friendly technology program for industry fishing process. Under normal conditions, the PPI Meureudu ice factory is currently producing ice cubes in excess of fishermen's needs, so ice cubes are sold by fishermen operating in the Peulimbang and Peudada areas, Bireuen Regency. Sometimes, when the fish catch is abundant, ice is not enough to meet the ice needs for ships at PPI Meureudu and must be supplied from Sigli, Pidie Regency. This study aims to determine the need for ice in fishing and handling operations to the feasibility of the ice factory business at PPI Meureudu. This research was carried out for one month, namely in November 2022 at the Meureudu Fish Landing Base (PPI), Meureudu City, Kec. Meureudu, Pidie Jaya Regency. The data used in this study are primary data secondary data. using business feasibility analysis. The results showed that the need for ice blocks at PPI Meureudu for fishing operations within one month was 221.80 tons, and the need for ice for fish handling activities at PPI Meureudu within one month required the amount of ice to be 2,879 blocks of ice or 144,864 tons which is the result of the analysis financial value obtained from the NPV Rp. 95,761,105 can be said to be feasible because the value is greater than 0. At an IRR value of 5% it can be said to be feasible because the results of the IRR calculation are greater than the discount factor, and a Net B/C value of 1 is said to be a breakeven project because = 1. These three values have been carried out in the Meureudu PPI block ice factory business that business it is worth continuing.Keywords:Business FeasibilityIce Block FacilityPidie Jaya

Abstract

This research was conducted on one of the Siak River tributaries that crosses the urban area in Pekanbaru, namely the Pengambang River. The Pengambang River flow is dammed to become a reservoir; one of its functions is as a source of raw drinking water. Increased activity along rivers and reservoirs certainly has an impact on water quality. The research was carried out in May-October 2023. Water sampling was taken at 3 points each along the river flow and in the Reservoir. The physicochemical water quality parameters measured include temperature, TSS, BOD, COD, DO, pH, TP, Nitrate, and Total coliforms for rivers and reservoirs, while Chorofil-a only for reservoirs. Water quality was evaluated using CCME-WQI, and the results of water quality evaluation according to CCME-WQI in the Pengambang River at all sampling stations could have been bad to marginal. At the same time, in the Reservoir, it was marginal. The CCME_WQI Index value in rivers ranges 42.33 to 54.97, while in reservoirs, it is higher 49-56, it indicated water quality in reservoir better than river. Parameters influencing water quality in rivers and reservoirs, especially TC and BOD come from household waste cage fish cultivation.

Abstract

Catfish (Clarias gariepinus) that are reared with probiotics as biofloc-forming agent is thought to increase the fish production. Applying swamp probiotics to the water media has never been studied to ensure the flocks' availability in the rearing media. This study aimed to determine the appropriate frequency of probiotics application collected from swamps for biofloc formation to improve the catfish production. This study used a completely randomized design with two treatments and three replications. The treatments were composed of different application frequency of swamp probiotics: (P1) once in 42 days of rearing and (P2) twice in 42 days of rearing. Data on flock volume, total bacterial colonies, absolute growth rate, feed efficiency, survival rate, and water quality were analyzed by T-test with a 95% confidence level. Meanwhile, the flock composition data were analyzed descriptively. The results showed that P2 obtained the best treatment with a floc volume of 68.33 10.41 mL/L, absolute length growth of 8.18 1.03 cm, absolute weight growth of 19.30 3.12 g, feed efficiency of 135.24 7.98%, survival rate of 89.33 6.21%, biomass production of 24639.50 1344.51 g, temperature of 28.85-29.59C, pH of 7.27-7.42, dissolved oxygen (DO) of 3.91-5.72 mg/L, ammonia of 0.45-1.15 mg/L, and total dissolved solids (TDS) of 717.33-885.50 mg/L. Therefore, swamp probiotics should be applied to catfish culture media twice for 42 days of rearing or once every 21 days.Keywords:BioflocCatfishProbiotics from swamp

Abstract

Anchovy is one of potential commodities widely found and caught by fishermen in FMA-572 West Sumatra. Examining its exploitation rate is a part of taking control and monitor toward the fishing activities to avoid overfishing possibility. This recent study aims to calculate exploitation rate and oceanographic characteristics of anchovy fishing grounds. The data was collected from Bungus Oceanic Fishing Port, West Sumatra in 2018-2022. Meanwhile, sea surface temperature and chlorophyll data were obtained from https://marine.copernicus.eu/ and https://oceancolor.gsfc.nasa.gov 2018-2022, respectively. The results showed that the exploitation rate of anchovies in 2020 and 2022 has exceeded maximum sustainable yield categorized as overexploitation with a percentage of 130.44% and 112.84%. Anchovy catches are significantly influenced by oceanographic factors with F value 0.00000115 ( 0.05). An increase in CPUE value is align with chlorophyll increase and in contrary to sea surface temperature. The findings are expected to give an overview related to anchovy fishing activities implementation and become an input for fisheries governance that lead to sustainable fisheries management.Keywords:FMA-572MSYOverfishingSustainable fisheriesStolephorus sp

Abstract

Rewataya Village is situated on Tanakeke Island, within the Takalar Regency. Despite its significance, previous studies have not addressed the mapping of changes in mangrove land area within this locale. The present research aimed to fill this gap by assessing alterations in mangrove land area from 2013 to 2023, alongside examining density and canopy cover conditions. The method employed for mapping changes in land area entailed utilizing the unsupervised method with maximum likelihood classification. Additionally, the assessment of mangrove conditions involved employing plot line transects to determine species density and hemispherical photography methods to evaluate canopy cover. Notably, two types of mangroves, namely Rhizophora mucronata and Rhizophora apiculata, are prevalent in this village. The mangrove species density in Rewataya Village, Tanakeke Island, is categorized as good. In addition, the canopy cover in Rewataya Village falls within the classification of very dense according to mangrove damage criteria. However, there has been a notable reduction in the mangrove ecosystem area between 2013 and 2023, with a decrease of 42.28 hectares (from 367.13 hectares to 324.84 hectares).Keywords: MangroveLandsat 8Rewataya villageUnsupervised
