Abstract

The salted fish processing industry was one of the small and medium-sized business sectors that played an important role in supporting the economy of coastal communities. Salted fish products not only have a relatively high economic value, but also increase the durability of marine catches through traditional preservation processes. However, amidst fairly broad market opportunities, salted fish processing business actors often faced various challenges, especially regarding production cost efficiency, raw material price transmission, and income instability. This study analysed production costs, revenues, and profits from salted fish processing. The method used in this study was the survey method. Based on the results of the research that had been conducted, it was found that the average cost incurred by salted fish entrepreneurs was IDR 47,702,088 per month, with revenues of IDR 56,612,500 per month. The average profit was approximately IDR 8,910,412 per month

Abstract

The growth of giant gouramy in the pre-enlargement phase is very important, so the fish can grow and develop optimally until the enlargement phase. Water temperature is one of the many factors that directly affect the growth of fish. Water temperature significantly affects the rate of egg hatching of giant gouramy and the development of larval organs. The aim of this research is to determine optimum of water temperature on the growth of giant gourami fingerlings in pre-enlargement phase on controlled tanks. This research used a completely randomized design method with four treatments and two replications. The treatments in this study were: Control (maintenance without water heater); P1 (maintenance at 30 oC); P2 (at 32oC); and P3 (at 34oC). This research was conducted for 30 days by using giant gouramy fingerlings measuring 3,11± 0,14 cm with 50 ind/tank. The results showed that giant gouramy fingerlings was cultured at 32oC experience an absolute length growth of 5.29±0.21 cm, a daily growth rate of 3.32±0.07% and a survival rate of 94±2.82%. This indicates that the maintenance water temperature of 32oC is able to provide optimal growth for giant gouramy fingerlings in the pre-enlargement phase.

Abstract

The exponential growth of environmental challenges, particularly those affecting water resources, necessitates innovative technological interventions beyond conventional approaches. This review explores the transformative potential of deep learning technologies in water quality management across different scales from controlled laboratory environments to complex oceanic systems. By analyzing recent developments, we identify how neural networks, especially convolutional and recurrent architectures, have revolutionized water quality parameter prediction, anomaly detection, and ecosystem monitoring. Integrating multi-modal data streams with advanced algorithms has enabled unprecedented predictive accuracy and real-time assessment capabilities, transforming reactive monitoring systems into proactive management frameworks. Despite significant progress, challenges remain in data standardization, model interpretability, and the practical deployment of these technologies in resource-constrained settings. This review critically assesses current research trajectories and identifies promising avenues for future development, emphasizing the importance of interdisciplinary collaboration in translating laboratory innovations to large-scale implementation for safeguarding our most precious resource

Abstract

This research was carried out in February 2021 in the Historic River Mangrove Tourism Area, Kayu Ara Permai Village, Sungai Apit District, Siak Regency, Riau Province. This study aims to analyze the rate of decomposition of inter mangrove litter. The method used in this study is a survey method and the determination of the sampling location by purposive sampling. The rate of decomposition of mangrove leaf litter was carried out by placing 10 g of litter in a litter bag on the mangrove forest floor in three zones for 4 weeks and taken every week as a sample. The results showed that the water quality, namely the temperature ranged from 28-30°C, salinity 30-31‰, and pH 6.1-6.4. The results of the calculation of the rate of decomposition of mangrove leaves obtained an average of 0.25–0.11 g/day. The results of the Anova test showed that the rate of decomposition of mangrove leaf litter was higher in zone 1, which is relatively always inundated by tides and is affected by sea waves.

Abstract

Polyculture is cultivation in one container that produces more than one species of fish simultaneously. The purpose of this study is to determine the effect on the growth of gouramy in polyculture system. This study uses an experimental method of Completely Randomized Design (CRD) 4 treatments and 4 repetitions that is P1 (15 species gouramy), P2 (10 species of limnetic lobster ad is species of gouramy), P3 (15 species of limnetic lobster and 15 species of gouramy), and P4 (20 species of limnetic and 15 species of gouramy). The data analysis used is analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) for futher test, while the quality of water is analysed descriptively. The observation result show that different stocking density treatment affects absolute length growth of gouramy (O.gouramy). This is because the stocking density of limnetic lobster (C. quadricarinatus) is different for each treatment on gouramy (O. gouramy). The highest average result of measure ment of absolute weight growth is 1,45 ± 0,017 g. This is because the stocking density of limnetic lobster (C. quadricarinatus) at P2 is low. Low stocking density provides suitable space for gouramy to move and live. The maintenance of the polyculture system is better done with 10 species of limnetic lobster and 15 species gouramy because it makes the best absolute length and weight growth.

Abstract

This study is to determine the relationship between primary productivity and nutrients in the coastal waters of Pelintung Village, Medang Kampai District, Dumai. The research was conducted in March 2022; the method used in this research is survey method and purposive sampling. The research location is divided into 3 station points namely tourist area, secondary vegetation forest area, and near industrial area. The results of the measurement of the highest primary productivity value are found at Station III which is 78.91 mgC/m2/hour which indicates mesotrophic water conditions, while the lowest primary productivity value is at Station II, which is 46.88 mgC/m2/hour which indicates oligotrophic water conditions. The results of the analysis of the concentration of nitrate and phosphate between stations also varied, namely for the nitrate value of 0.04 – 0.05 mg/L which was included in the less fertile category, while the phosphate concentration was 0.042 – 0.048 mg/L which was included in the fertile category in the waters. Furthermore, the relationship between nitrate concentration and primary productivity is a correlation coefficient value (r) = -0.070 which means that there is a weak relationship between nitrate concentration and primary productivity. Meanwhile, the relationship between phosphate concentration and primary productivity is the correlation coefficient (r) = 0.965, which means that there is a very strong relationship between phosphate concentration and primary productivity. So it can be concluded that nitrate and phosphate nutrients can affect the primary productivity of water.
