Abstract

The estuary of Salok Api River in Balikpapan City is geographically located right across the Makassar Strait which is a strategic area supporting the economy of the surrounding city. The aquatic environment in any watershed acts as a carrier of various pollutants and affects the water quality in the estuarine area. The main objective of this study is to assess and identify pollutants that flow into the water environment around extensive ponds in Balikpapan City for aquaculture activities. The STORET method was used in this study to determine the water quality status. Water quality data were collected at six different locations around extensive ponds in Balikpapan City in February - March of 2023. A total of 13 water quality parameters (brightness, temperature, TDS, EC, salinity, pH, DO, ammonia, nitrite, nitrate, phosphate, BOD, and COD) were analyzed at six sites to assess the STORET index at each site. The average STORET index at the six sites was (-32, -26, -26, -26, -26, and -38). The results showed that four sites were classified as moderately polluted and the other two sites were classified as heavily polluted. The STORET index at each location is high and the implication is that the area has moderate to poor water quality status due to several parameters such as EC, salinity, pH, DO, ammonia, phosphate, and COD.

Abstract

Freshwater lobsters are one of the crustacean commodities that have started to be developed through cultivation. Besides having high nutritional value, freshwater lobsters have a stable sales value or price throughout the year. Freshwater lobster is a crustacean commodity that is not easily stressed or easily attacked by disease. The availability of calcium is essential for lobster growth, especially the formation of its shell. This research aims to determine the effectiveness of adding calcium carbonate at different time intervals by adding 150 mg/L CaCO3 lime. The study was conducted from June to July 2020 at the Aquaculture Environmental Laboratory, Bogor Agricultural Institute. The research used a Completely Randomized Design (CRD) with five treatments and three replications. The treatment used was K+ and K-, and the time interval for adding CaCO3 was once every five days, once every ten days, and once every 15 days. The aquarium measures 100 x 50 x 51 cm with a water height of 21 cm. The lobster used measures 1.5 cm. The research results after statistical testing showed that aquarium A1 (addition of CaCO3 every five days) experienced an increase in length of 0.67 cm. Weight of 0.67 g, B1 (addition of CaCO3 every ten days) experienced an increase in length of 0.87 cm and weight of 0.78 g, C1 (addition of CaCO3 every 15 days) experienced an increase in length of 0.97 cm and weight of 0.98 g, K+1 experienced an increase in length of 1.05 cm and weight of 1.06 gr, K-1 experienced an increase in length of 0.46 cm and weight of 0.45 g.

Abstract

Belawan is a coastal area located in Medan Belawan District, North Sumatra Province. The aim of the research is to determine the feasibility status of the study location if it is developed as a location for floating net cages (KJA). The research was carried out in the sea waters of Belawan in August–September 2022. The research parameters observed during the research were hydrooceanographic data and water quality data including physical parameters, chemical parameters, biological parameters. Determination of water quality status using the STORET Index, CCME WQI Index and principal component analysis (PCA). Observation parameters during the research were clinical symptoms, histological observations and growth performance of Asian sea bass. The research results show that tides, COD and turbidity are parameters that do not comply with water quality standards. The types of phytoplankton consist of 15 species and 4 classes, namely Cyanophyceae, Chlorophyceae, Bacyllariophyceae and Dynophyceae. Observation total vibrio count (TVC) shows that in all water samples it is Log 105 CFU/mL and in snapper organs (gills, liver, kidneys) there are Log 104-105 CFU/g. The results of the research can be concluded that for each zone in Belawan waters there is no difference in the level of pollution between zones in terms of the STORET index (moderately polluted) and the CCME WQI index (marginal) with limiting factors namely COD and turbidity. Belawan waters are in less than suitable condition in August–September for snapper cultivation activities in floating net cages (KJA) characterized by low SR and ADG values. Keywords: Belawan Waters, CCME WQI index, STORET index, principal component analysis (PCA), water quality monitoring ABSTRAK Belawan termasuk kawasan pesisir yang terletak di Kecamatan Medan Belawan, Provinsi Sumatera Utara.

Abstract

This experiment was conducted to study the activity, protein retention, daily growth rate, and production of Dendronereis pinnaticirris cultured in different soil substrates. Forty tested worms with average body weight of 150 mg were adapted in laboratory for 30 days. Thereafter, worms were cultured for 30 days in the 13.6 L aquaria and equipped with aeration system. A triplicate experiment was conducted using 10 cm depth of sterilized soil substrate with particle diameter of either 63‒250 μm, 250‒500 μm, or without substrate. The results showed that (1) D. pinnaticirris always swims actively when cultured in the medium without substrate, thereby resulting into the mass mortality (96.7%); (2) the substrate with particle diameter of 63‒250 μm generated significantly higher daily growth rate, survival rate, and production of D. pinnaticirris, but protein retention and feed efficiency were insignificance with those cultured in the substrate of 250–500 μm.Keywords: substrate, protein retention, production, Dendronereis pinnaticirris

Abstract

ABSTRACT A series of experiments was performed to analyze protein digestibility, ammonia excretion, and also heterothropic bacteria and phytoplankton dynamics in the catfish Clarias gariepinus culture. In the digestibility experiment, catfish with an individual initial size of 43.67±0.83 g were stocked into 120 L conical fiberglass tanks at a density of 20 fish per tank. Fish were fed on with commercial diet supplemented with Cr2O3 indicator at a concentration of 1%. In the ammonia excretion experiment, catfish with an individual size of 111.6±9.5 and 40.6±3.4 g, respectively,  were placed into a 10 L chamber filled with 8 L of water. Total ammonia nitrogen (TAN) in the chambers were monitored every hour for six consecutive hours. In the bacteria and phytoplankton dynamics experiment, catfish were stocked in the 25 m2 concrete tanks which was divided into two compartments (catfish 10 m2, and heterotrof compartments 15 m2). Catfish with individual size of 42,5±0 g were stocked into the tanks at a density of 100 fish per tank. Water was recirculated from catfish compartments to heterotrophic compartments. Fish were fed with floating feed. Molasses as carbon source for heterotrophic bacteria was applied daily. The experiment was conducted for six weeks. The results showed that the protein digestibility was 61.97±7.24%. Larger fish (size of 111.6 g) excreted ammonia at a rate of 0.008±0.003 mg TAN/g fish-weight/hour, which was lower than that of the smaller catfish (size of 40.6 g), i.e. 0.012±0.004 mg TAN/g fish-weight/hour. Keywords: protein digestibility, ammonia excretion, catfish  ABSTRAK Serangkaian penelitian telah dilakukan untuk menganalisis ketercernaan pakan dan protein, ekskresi amonia, serta dinamika bakteri dan fitoplankton pada budidaya ikan lele (Clarias gariepinus).

Abstract

ABSTRACTCurrently, supply of sludge worm (Tubifex sp.) merely came from wild, so that it could not meet demand for fish hatchery. Additionally, harvest from the wild did not have a quality assurance, due to the possibility of sludge worm becoming an agent of disease. This study was conducted to evaluate the production of sludge worm culture by utilizing catfish culture waste (Clarias sp. ) in bioflok system. In this system, water from catfish culture media flowed into sludge worm culture media using recirculation systems. This study used a completely randomized design with four treatments and two replications, in which treatment A (addition of catfish culture waste from intensive system), treatment B (addition of catfish culture waste from biofloc system), treatment C (the addition of fermented chicken manure at the beginning of experiment as negative control), and treatment D (addition of fermented chicken manure at the beginning of experiment and then every five days as positive control). The results showed that the highest production was obtained by treatment B at biomass growth of 0.97 kg/m2 and sludge worm density of 388.000 individu/m2. Keywords: sludge worm, biofloc, chicken manure, catfish, catfish culture waste  ABSTRAK Saat ini pasokan cacing sutra (Tubifex sp.) hanya berasal dari alam, sehingga belum mencukupi permintaan untuk kegiatan pembenihan ikan. Selain itu, hasil tangkapan dari alam tidak memiliki jaminan kualitas, karena cacing sutra dapat menjadi agen penyakit.
