Abstract

Goldfish cultivation currently faces several major problems, such as the high prevalence of parasitic infections, particularly those caused by Argulus japonicus. This study aims to identify and analyze the relationship between MCV, MCH, and MCHC values as indicators of parasitic anemia in goldfish (Cyprinus carpio) infested with Argulus japonicus and the effect of bromelain enzyme supplementation in commercial feed. The research stages include aquarium and maintenance media preparation, bromelain enzyme production from pineapple core, treatment feed production, and Argulus japonicus culture. The experiment employed a factorial-based Completely Randomized Design (CRD) comprising eight treatment combinations, and data analysis utilized the Pearson correlation test in conjunction with multiple linear regression. The results showed a strong positive relationship between MCV and MCH, reflecting normal erythropoiesis, in which erythrocyte enlargement is followed by an increase in hemoglobin per cell. In practice, these findings can be used to detect anemia early, potentially reducing aquaculture productivity. The application of the results of this research can potentially increase fish resistance to disease and support production efficiency in intensive fish farming

Abstract

Mangrove ecosystems in the coastal area of West Tanjung Jabung Regency are under increasing pressure from anthropogenic activities, highlighting the need for continuous monitoring of changes in their spatial extent and density. This study aims to analyze the changes in the area and density of mangrove ecosystems along the coastal region of Tanjung Jabung Barat Regency during the period 2015–2024 using Landsat 8 OLI satellite imagery. The data were obtained from the USGS Earth Explorer (path 125, row 61) with cloud cover less than 10%. Image processing involved several stages, including preprocessing, band composition, visual digitization, and supervised classification using ArcGIS 10.8 software. Mangrove vegetation density was analyzed using the NDVI (Normalized Difference Vegetation Index), which was categorized into three density classes: sparse, moderate, and dense. The results showed that the total mangrove area decreased by 14%, from 3,488.78 ha in 2015 to 3,009.98 ha in 2024, representing a reduction of approximately 478.8 ha. The most significant decreases occurred in Sinar Kalimantan Village (172.82 ha) and Sungai Dualap Village (42%), while a slight increase was observed in Pangkal Duri Ilir Village (1%). The NDVI-based density analysis indicated that dense mangrove areas increased substantially in Muara Seberang Village by 377.54 ha, whereas the largest decline occurred in Sinar Kalimantan Village by 78.72 ha. Overall, the findings reveal a trend of mangrove degradation mainly driven by land conversion and anthropogenic activities, alongside localized improvements likely due to rehabilitation efforts. These results provide valuable insights for sustainable management and conservation planning of mangrove ecosystems in the coastal zone of Tanjung Jabung Barat Regency

Abstract

The salted fish marketing business in Pasar Belakang Village, Sibolga Kota District, Sibolga City has developed as a solution to the low absorption of fresh fish in the market while also providing employment opportunities for the local community. However, this business faces challenges related to fluctuations in the prices of raw materials, which affect production costs and profitability. The purpose of this study is to analyze the total costs, revenues, and profits, as well as to assess the financial feasibility of salted fish marketing businesses in Pasar Belakang Village, Sibolga Kota District, Sibolga City. This research employed a survey method involving 27 business actors. The data were analyzed using profitability analysis, Break Even Point (BEP), Revenue Cost Ratio (R/C), Return on Investment (ROI), and Payback Period (PP). The findings indicate that business actors who purchase ready-made salted fish incurred an average investment cost of Rp34,230,130, fixed costs of Rp871,010, and variable costs of Rp110,767,435 per month, with an average sales volume of 4,205 kg, revenues amounting to Rp121,330,435, and profits of Rp9,691,990. Meanwhile, businesses producing salted fish independently required an investment cost of Rp54,418,750, fixed costs of Rp1,591,025, and variable costs of Rp94,091,250 per month, with an average sales volume of 6,975 kg, revenues of Rp116,500,000, and profits of Rp20,817,725. The feasibility analysis shows that both types of businesses are financially viable, with BEP values of 347 kg and 495 kg, R/C ratios of 1.09 and 1.22, ROI of 28% and 38%, and Payback Periods of 0.29 years (3.48 months) and 0.22 years (2.64 months), respectively. Based on these results, the salted fish marketing business in Pasar Belakang Village, Sibolga Kota District, Sibolga City is declared financially feasible, with independently producing businesses demonstrating better financial performance.

Abstract

Batu Belubang Village plays a strategic role in the fisheries sector, with the floating lift net (bagan apung) as the main fishing gear, yet this sector continuously faces major challenges, notably catch fluctuations and rising operational costs. Within the framework of sustainable fisheries business, financial feasibility analysis serves as a fundamental theoretical basis for assessing business efficiency and resilience. Given the lack of comprehensive financial studies in this area, this research aims to analyze the financial feasibility of the floating lift net business through the indicators of profit (????), Rasio Penerimaan terhadap Biaya (R/C), Payback Period (PP) and Return on Investment (ROI). Understanding these metrics is crucial for providing strategic insight to fishermen and the government in managing resources for sustainable welfare.The analysis results show a business profit of Rp 8.283.963.333-,with an R/C value of 63.72, indicating that every rupiah of cost generates 63.72 times the revenue. The measured Payback Period is only 0.069 years or approximately 25 days, signifying a rapid return on capital. The ROI value, reaching 14.29%, confirms the financial feasibility of the floating lift net business, but this low figure indicates operational inefficiency and vulnerability to market fluctuations. Therefore, strategic interventions focused on processed product development, digital market expansion, and cost efficiency optimization are necessary to increase the ROI and ensure the business’s sustained profitability.
