Abstract

The Ir. H. Djuanda Reservoir in Purwakarta Regency is one of the priority areas in the implementation of the Citarum Harum programme, which focuses on restoring the environmental quality of the Citarum River. This study aims to determine the abundance and community structure of phytoplankton in Ir. H. Djuanda Reservoir after the implementation of the Citarum Harum Programme. This study used purposive sampling method at 11 stations in Ir. H. Djuanda Reservoir in August 2024. Phytoplankton abundance was measured based on APHA and community structure was analysed using ecological indicators including diversity, variability and dominance indices. Water quality assessment was determined using the STORET method as the analytical instrument. Statistical analyses were also conducted to assess differences in phytoplankton abundance between stations. The results showed that the phytoplankton community in Ir. H. Djuanda Reservoir during the study consisted of five classes and 31 genera with low diversity and evenness and no dominance. Phytoplankton abundance ranged from 389,048 - 710,536 cells/L and differed between stations (P<0.05). The relative abundance of Cyanophyceae (46.60%) was almost equal to Chlorophyceae (43.45%) indicating a change in the environment for the better. This study is expected to be one of the references for monitoring and evaluation materials for the implementation of the Citarum Harum programme as empirical evidence that there has been a change in the water quality status of Ir. H. Djuanda Reservoir from heavily polluted to moderately to lightly polluted.

Abstract

Litopenaeus vannamei farming intensively cannot be separated from various problems. One of the problems faced by farmers is the availability of seeds in terms of quantity and quality. Therefore, this study aims to determine the production techniques of L. vannamei shrimp nauplii produced from the mass spawning process to support the increase in the number of L. vannamei shrimp production. Mass spawning has an impact on the number of nauplii produced and the effectiveness of broodstock maintenance. This study was carried out in Banten, Indonesia. This study was conducted by surveying and observing the stages of broodstock management, spawning, nauplii harvesting, and the production of nauplii. The results of the study showed that several aspects must be considered: (1) broodstock management that includes feeding and monitoring water quality, (2) mass spawning, and (3) harvesting and production of nauplii. During the rearing period, feed, such as pellets, marine worms, and squid, was administered to accelerate the gonad maturation process, and water quality was controlled. The results of mass spawning were obtained Maturation Rate ranges 12.66 - 21.66%, Matting Rate (MR) ranges 40 - 85%, Fecundity ranges 231,951 – 486,250 eggs/shrimp, Fertilization Rate (FR) ranges 60.45 – 72.37%, and Hatching Rate (HR) ranges 71.66 – 87.24%. Total nauplii production was 4.996.398 shrimp for 28 days. Total production was slightly lower than previously reported, which was caused by an inaccurate matting process.

Abstract

Chlorella sp. is one of the microalgae that is used as natural food because it contains more nutrients compared to artificial food. In order to obtain microalgae such as Chlorella sp. The aim of the cultivation process is to obtain microalgae in good condition, so that the availability of natural food can be fulfilled through the culture process. To support the culture process, organic materials are needed in the form of POC which are easy to find and of course naturally available. One example is the use of POC organic material which is produced from adding coconut water, rice washing water and chicken egg shells, then fermented using EM4. The aim of this research was to determine the effect of using liquid organic materials (POC) on the density of Chlorella sp. and the best concentration treatment during the long-term culture process. The research method applied was a Completely Randomized Design (CRD), including four treatments and three repetitions throughout the research. Chlorella sp cell density. The highest occurred in treatment K (control concentration 25 ml/container), then treatment B (concentration 200 ml/container), treatment A (concentration 100 ml/culture container), and the lowest density was in treatment C (concentration 300 ml/container). The use of ingredients (POC) derived from coconut water, rice washing water, and chicken egg shells has an effect on the cell density of Chlorella sp. with a p value <0.05). The highest density was on day 10 with a density value of Based on the results obtained from the use of POC as a natural fertilizer for the cultivation of Chlorella sp. For this reason, it is hoped that cultivators need to use POC in the surrounding environment as an alternative fertilizer to replace chemical fertilizers because it has good nutritional content for the Chlorella sp cultivation process and does not pollute the aquatic environment.

Abstract

Mangrove forests in Subang Regency have experienced changes in area coverage due to the expansion of aquaculture ponds and coastal abrasion. This study aims to analyze the changes in mangrove area and density in Blanakan Bay, Subang Regency, during the period 2018–2022 using Landsat 8 satellite imagery. The method employed is a survey approach utilizing multispectral classification. The main assumption of this study is that changes in mangrove coverage can be observed through multitemporal satellite imagery that has undergone geometric and radiometric correction. The digitized Landsat images were overlaid to identify spatial changes in mangrove cover 2018-2022. Spatial analysis was conducted using Supervised Classification techniques and the Normalized Difference Vegetation Index (NDVI) to classify mangrove areas based on their density levels. The results showed that the mangrove area in 2018 was 553.2 hectares, which decreased to 384.2 hectares in 2022, indicating a reduction of 169 hectares.

Abstract

Bontang City, located in East Kalimantan Province, has a larger marine area than land area, offering significant potential in marine fisheries resources. One of the abundant yet undervalued marine commodities is bawis fish (Gerres sp.), which remains economically underutilized. This low economic value presents a challenge, particularly for coastal communities that depend on the fisheries sector for their livelihoods. Increasing the added value of bawis fish through processing into higher-value products is therefore essential. One such initiative is the production of bawis fish chips, developed by the Processing and Marketing Group (Poklahsar) Saputra Snack, led by a local entrepreneur in Bontang. This study aims to assess the economic value added from bawis fish chips using the Hayami value-added analysis method. The findings indicate that the product yields an added value of IDR 27,151 per kilogram, with a value-added ratio of 37%. This implies that for each kilogram of raw bawis fish processed, an additional economic value of IDR 27,151 is generated. Based on the Hayami criteria, this level of value addition is classified as moderate (15%–40%). The results suggest that processing bawis fish into chips has the potential to serve as an effective strategy for enhancing the economic well-being of small-scale fishery enterprises.

Abstract

The growth of Nirwana tilapia (Oreochromis niloticus) is strongly influenced by feed and environmental conditions in aquaculture systems. In Indonesia, tilapia productivity is often constrained by feed efficiency and fluctuating water quality. Natural feed such as bloodworms (Chironomus sp.) contains high protein levels that support length growth, while pellets provide complete nutrients for weight gain. This study aimed to evaluate the effects of bloodworms, pellets, and their combination on the growth performance of Nirwana tilapia fingerlings, as well as on water quality (temperature, pH, dissolved oxygen, and ammonia). A Completely Randomized Design (CRD) was applied with three treatments: A (15% bloodworms), B (5% pellets), and C (a combination of 7.5% bloodworms + 2.5% pellets), each with four replications. The fingerlings measured 3–4 cm and were approximately two months old, reared over a period of 50 days. The results showed that all treatments led to increases in weight and length; however, based on analysis of variance (ANOVA), there were no significant differences (p > 0.05) in all growth parameters: weight gain (2.20–2.22 g), length gain (1.32–1.48 cm), specific growth rate (2.41–2.66%/day), daily weight gain (2.73–2.85%/day), and daily length growth (0.0196–0.0210 cm/day). Descriptively, treatment B yielded the highest weight, while treatment A had the highest daily length growth. Water quality remained within optimal ranges (25.5°C temperature, pH 8.2–8.3, DO 4.5–4.7 mg/L, ammonia 0.00–0.01 mg/L). Bloodworms were more effective in stimulating length growth, whereas the feed combination was more efficient in increasing body weight. This study contributes to the development of alternative feed formulations and provides practical recommendations to enhance aquaculture productivity efficiently, sustainably, and in an environmentally friendly manner.
