Sidoarjo has a large aquaculture area, but it is a dense city with rapid industrial development. Thus, aquaculture activities such as milkfish, which is a leading commodity, are threatened by water pollution by waste and decreased water quality. Related to this, the purpose of this study is to examine the content of heavy metals lead (Pb) and arsenic (As) in milkfish (Chanos chanos). These metals are substances that have the potential to pollute river aquaculture water sources because they are found in many industrial and household wastes such as paint waste, batteries, insecticides, and pesticides, which are also likely to accumulate in aquatic biota. This study used observation and purposive sampling methods for sampling and measuring water quality, while testing heavy metals Pb and As with ICP-MS, and quantitative descriptive data analysis of several parameters including Geo-Accumulation Index (Igeo), Contamination Factor (CF), and Bio-Concentration Factor (BCF). Based on the results of the study, Pb content in water at the three points was not detected / ND. As in water obtained an average of 0.030 mg/l. While, lead in sediment the average value is 7.84 mg/kg, and 3.30 mg/kg for As. Pb in milkfish was found to average 0.082 mg/kg, and As was 0.277 mg/kg. Overall, Pb and As at the three points were still below the established threshold. However, the average concentration of As metal in water has exceeded the quality standard of KepMen LH No. 51 Th. 2004. Based on the calculation data of the Igeo index, CF, and BCF, the accumulation rate is low so that the level of pollution and contamination is considered safe. Water quality measurements are said to be good for milkfish aquaculture growth at all three points because they meet the optimal value standards for salinity, pH, DO, brightness and temperature.

C. vulgaris is photoautotrophic, which refers to microalgae that require light as an energy source. One of the light sources used to affect pigments in microalgae is UV light. The advantage of UV light is that it can change gene composition, which results in mutant genes in biopigment mutations and causes a higher number of activities compared to the natural ones, thereby increasing the growth, carotenoids, and chlorophyll-a of microalgae. The aim of this research is to determine the effect of oxidation stress of UV light on growth, carotenoids and chlorophyll-a content of Chlorella vulgaris. The treatments were given based on differences in the power of the UV-C light from, 8W, 15W and 30W. This study used the UV-Vis Spectrophotometer method was used to calculate growth, carotenoids and chlorophyll-a. Data were analysed using ANOVA test, Duncan's Multiple Range Test, and Principal Component Analysis (PCA). The results showed a significant effect of UV-C light. The best treatment was found in the administration of 30 W UV light, with the results of growth was 4.7746 × 106 cells/ml, content of carotenoids was 1.75 mg/ml and chlorophyll-a was 4.67 mg/ml of C. vulgaris. Biopigment can absorb radiation from UV-C light, which causes these microalgae to survive in environmental stress conditions. Absorbed light can affect the spectrum of pigments, thereby increasing growth, carotenoids, and chlorophyll-a.

Abstrak Ikan bandeng (Chanos chanos) merupakan potensi perikanan payau. budidaya ikan bandeng di Jawa Timur masih menggunakan sistem tradisional, dimana air baku tambak menggunakan aliran air sungai setempat dan pasang surut air laut. Budidaya ikan bandeng secara tradisional memiliki kelemahan yaitu sulit menjaga kualitas air sehingga mudah tercemar oleh limbah rumah tangga maupun limbah industri. Bioakumulasi logam berat merupakan proses peningkatan konsentrasi suatu zat yang masuk kedalam tubuh mahkluk hidup. Salah satu logam berat yang dapat mencemari perairan yaitu logam timbal (Pb). Penelitian ini bertujuan untuk mengetahui konsentrasi limbah timbal (Pb) yang terkandung pada air, sedimen, dan daging ikan bandeng di tambak tradisional Desa Watuagung (Gresik), Desa Kalanganyar (Sidoarjo), dan Desa Jarangan (Pasuruan). Selain itu, untuk mengetahui tingkat pencemaran Pb di Desa Watuagung (Gresik), Desa Kalanganyar (Sidoarjo), dan Desa Jarangan (Pasuruan). Metode penelitian ini dengan mengambil data secara acak (purposive random sampling). Dengan pengambilan sampel di tiga lokasi yang berbeda, setiap lokasi terdapat tiga stasiun yang diuji. Hasil dari penelitian ini, kandungan logam Pb pada air dan daging ikan bandeng tidak terdeteksi, pada sedimen terjadi akumulasi logam Pb namun kadarnya masih dibawah baku mutu dan masih layak untuk kegiatan budidaya ikan bandeng. Tingkat pencemaran logam Pb pada ketiga lokasi tambak (Gresik), (Sidoarjo), dan (Pasuruan) masih tergolong aman. Nilai indeks pencemaran Igeo, CF, dan BCF masih dibawah ambang batas dan masih tergolong aman. Kata Kunci: Ikan Bandeng, Logam Berat, Timbal, Bioakumulasi Abstract Milkfish (Chanos chanos) is a potential brackish water fishery. milkfish cultivation in East Java still uses a traditional system, where the raw water of the pond uses local river water flow and sea tides. Traditional milkfish cultivation has the disadvantage that it is difficult to maintain water quality so that it is easily contaminated by household waste and industrial waste. Bioaccumulation of heavy metals is the process of increasing the concentration of a substance that enters the body of a living creature. One of the heavy metals that can pollute waters is lead. This study aims to determine the concentration of lead (Pb) waste contained in water, sediment, and milkfish meat in traditional ponds in Watuagung Village (Gresik), Kalanganyar Village (Sidoarjo), and Jarangan Village (Pasuruan). In addition, to determine the level of Pb pollution in Watuagung Village (Gresik), Kalanganyar Village (Sidoarjo), and Jarangan Village (Pasuruan). This research method is by purposive random sampling. By taking samples at three different locations, each location has three stations that are tested. The results of this study, the Pb metal content in water and milkfish meat was not detected, in the sediment there was an accumulation of Pb metal but the levels were still below the quality standards and were still suitable for milkfish cultivation activities. The level of Pb metal pollution in the three pond locations (Gresik), (Sidoarjo), and (Pasuruan) was still relatively safe. The pollution index Igeo, CF, and BCF were still below the quality standards and were still safe. Keywords: Milkfish, Heavy Metal, Lead, Bioaccumulation

This study aims to evaluate the financial performance of the koi fish farming industry (Cyprinus rubrofuscus) in Indonesia through a selective breeding program. Data collected between 2021 and 2024, covering business development, operational costs, investment costs, and capital estimates, was obtained from 24 koi fish farming businesses in the Java region. Businesses using genetic screening aim to reduce financial disparities, which is different from traditional aquaculture methods. The analysis's results indicate that the implementation of the selective breeding program in a scientific manner yielded a higher profit margin of 34.2% than the traditional method, which only reached 18.7%. Although the initial investment is more substantial (about Rp28,5 million per hectare), the time frame required to pay for the investment is more efficient, i.e., between 18 and 24 months. The price of koi fish is higher than the market price, possibly reaching 2.8% of the price of koi fish, with the selling price per tail ranging from Rp450,000 to Rp1,200,000. In addition, there was a 15% increase in feed efficiency and a 3% decrease in mortality, which means a 7.8% reduction. Thus, this selective breeding program can improve koi farming production and sales performance by applying genetic technology, which can help overcome the financial crisis in the aquaculture sector in developing countries.

Manyar Sub-district, located in Gresik, is home to many fish and shrimp pond farmers. Vannamei shrimp farming is a particularly popular aquaculture activity in Tanggul Rejo Village, Manyar Sub-district. However, the shrimp and fish farming industries face challenges in production, primarily due to diseases arising from declining water quality. Many pond farmers lack knowledge about the importance of water quality management to support successful shrimp farming, highlighting the need for appropriate technology to improve production. This study aimed to apply probiotics to manage the water quality of vannamei shrimp rearing media in Manyar Sub-district. The activity was carried out in several stages, including identifying and mapping the problems faced by farmers, delivering educational materials about the use of probiotics in shrimp farming, providing assistance for probiotic application, and monitoring and evaluating the results. The findings showed that the application of probiotics to the rearing water media every two days resulted in low ammonia and nitrite levels, as well as adequate oxygen levels and pH, which are conducive to vannamei shrimp cultivation.

Graphical Abstract Highlight Research Salinity is the critical influencing the distribution of macrobenthos species based on habitat (seawater and freshwater species) in estuaries. The brackish water station exhibited the highest macrobenthos abundance, whereas the seawater station showed the highest meiobenthos abundance. Corresponding water quality parameters markedly influenced the abundance of each benthic group. The calculation of abundance and biological indexes classified the Bengawan Solo estuary as relatively stable. Abstract As key aquatic organisms, benthos are a reliable indicator of water quality owing to their relatively fixed habitats, limited mobility, and residence at the bottom of the water. This study aimed to analyze benthos’ biodiversity and community structure as bioindicators in the waters of the Bengawan Solo estuary that important for fishery activities conducted by local fishermen community. A descriptive analysis method was employed, involving identifying and analyzing benthos in density, biological indexes, and principal component analysis (PCA). The macrobenthos species composition consisted of Gastropoda, Bivalvia, Maxillopoda, Malacostraca, Polychaeta, and Clitellata while meiobenthos comprised Foraminifera, Bivalvia, Gastropoda, and Polychaeta. Macrobenthos density was 288 ind./m2, whereas meiobenthos density was 16 ind./10 cm2. Both macrobenthos and meiobenthos exhibited a moderate diversity index and a medium evenness index, although evenness values tended to be higher in macrobenthos. The dominance index for both macrobenthos and meiobenthos showed moderate values. PCA analysis revealed that macrobenthos, Bivalvia, Gastropoda, and Clitellata density was influenced by brightness and turbidity, Malacostraca and Maxillopoda density by salinity, and Polychaeta density by dissolved oxygen. In meiobenthos, Gastropoda and Foraminifera density was influenced by salinity, whereas Bivalvia and Polychaeta density was affected by brightness and turbidity. Density and biological index results indicate that the Bengawan Solo estuary is relatively stable.

Grouper (Epinephelus sp.) is a marine fishery commodity that is widely cultivated in marine cages and ponds. The export market demand for grouper fish continues to increase every year by 30.75% every year, so there is a need for improvement, through various technological applications. The main obstacle in cultivating grouper fish in ponds is the decline in water quality and disease attacks, which can cause up to 100% crop failure, just 3 – 5 days after infection. One effort that can be implemented is the cultivation method with the Immuno-Probiocirculation System (SIPBR). Brondong sub-district is one of the areas in Lamongan which has large fisheries potential, especially for breakwater water pools, which are the top among other districts. There have been many cases of grouper deaths in ponds to date, which are caused by disease attacks and water quality. The aim of this community service activity is to apply the Immuno-Probioculation System fish aquaculture technology in traditional plus pattern ponds (SI-PBR), increasing grouper fish production in Lamongan Regency, East Java. Observational method which includes socialization / counseling, planning and guidance for implementing SI-PBR technology in one period (three months). These results show positive indications. There is an increase in farmer knowledge, the SI-PBR method can reduce ectoparasite infestation and increase grouper yields from 272.43 kg / ha to 87.66 kg / ha, meaning an increase of 334%. The conclusion from this activity is that the SI-PBR model can increase fish production and can be applied in wider areas in the Lamongan region.
