The Banggai cardinalfish (Pterapogon kauderni) is a species of ornamental fish endemic to the Banggai Archipelago, Central Sulawesi, Indonesia. The high level of exploitation has caused the population of the proud fish to decline. The government seeks conservation by issuing KEPMEN KP Number 49 of 2018 concerning the Protection Status of Banggai cardinalfish. The purpose of this study/research is to determine the effectiveness of implementation after the policy is issued. Bali is one of the exit points for the export trade of the Banggai cardinalfish commodity. Banggai cardinalfish export from Bali in 2019-2020 only reached 60 thousand, increasing to 111 thousand fish with a frequency of 303 export data in 2021. Export destinations are the United Kingdom, France, China, Taiwan, Hongkong, Denmark, Netherlands, Brazil, Poland, and Germany. Banggai cardinalfish in its trade must be free from disease infections, listed in the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia No. 17 of 2021. Commodities must be examined by checking for types of quarantine fish diseases, namely Megalocytivirus infection. The prevalence value of Megalocytivirus or Banggai Cardinal Iridovirus (BCIV) from Banggai cardinalfish to exporters in Bali in 2020 was 1.49 and in 2021 it was 4.10. The current condition of the Banggai fishery in its utilization must meet the requirements attached to the Indonesian Minister of Maritime Affairs and Fisheries Decree No. 21 of 2021 regarding quotas, and Government Regulation Number 85 of 2021 regarding PNBP rates.

Abstract. The screen-printing process produces wastewater like organic compounds that are difficult to degrade and heavy metals such as chromium, copper, manganese, and lead, which are toxic and can accumulate in the human body through the food chain. Phytoremediation is one method that utilizes plants' ability to reduce organic and inorganic pollutants, including heavy metals. Objective: This study aimed to describe the concentration of screen-printing waste that can be tolerated by apu wood plants and analyze the effectiveness of apu wood as a heavy metal remediator. Technology or Method: The method used in this research is a combination of filtration and phytoremediation using apu wood to reduce heavy metals such as Pb and Cr,6+ and a preliminary test of Pb and Cr6+ contained in the screen-printing wastewater was carried out. Results: Apu wood lives and thrives on screen-printing wastewater, with an average of 34 new individuals' tillers growth within 15 days. The propagation of apu wood in screen-printing wastewater produced total biomass with an average of 145 grams per reactor. The effectiveness of apu wood as a remediator of Pb was 13.65%, and accumulated in the leaves was 0.0911 mg/L. The accumulation of Cr6+ in the leaves was 0.6635 mg/L. The Cr6+ component in the waste during 15 days of treatment did not show a positive effect on metal removal because the higher chromium element oxidation reaction occurred in the wastewater during the research process. Keywords Apu wood; chromium (VI); filtration; phytoremediation.

Many freshwater fish farming activities are carried out to meet the increasing demand for fish consumption. One commodity with high market demand is African catfish (Clarias gariepinus). The success of cultivation activities is the maintenance of broodstock is very influential on the eggs production. It is necessary to pay attention to the nutrients in the feed during cultivation. This study aims to determine the effect of adding soybean oil to feed on hatching eggs carried out at the Regional Technical Implementation Unit (UPTD) of Freshwater Aquaculture, Denpasar City. African catfish (C. gariepinus) were fed twice a day with feed mixed with soybean oil with three treatments namely 0%, 3% and 5% for five months. The fecundity and hatchability of eggs were calculated using a 10x10cm transect and analyzed using ANOVA analysis. Water quality observations were carried out once a week and ammonia at the end of each month. The results of this study obtained that fecundity values ranged from 214-546 grains/transect and egg hatchability values ranged from 0-62,62%. The results of observations of water quality showed a value that could still be tolerated by African catfish during the study. These results indicate that adding of 3% soybean oil to the broodstock feed of African catfish helps to increase the quality and quantity of hatching eggs.

Indonesia has a high potential for pearl oyster farming due to its diverse marine habitats, warm waters, and abundant supply of seaweed, which is the preferred food for pearl oysters. Indonesia is home to several species of pearl oysters, including the Pinctada maxima, which are prized for their large size and the quality of their pearls. Water quality plays a crucial role in the cultivation of Pinctada maxima. Factors such as temperature, pH, salinity, dissolved oxygen levels, and the presence of pollutants and pathogens can all impact the health and survival of Pinctada maxima. In addition to feed quality and seed availability, good water quality management is the key to the success of this biota seedling. This research was carried out by measuring parameters including temperature, salinity, pH, and dissolved oxygen levels in the waters temporally in the morning and evening every day of cultivation. Variables of ammonia, nitrite, total suspended solids, total bacteria, and vibrio bacteria were carried out once a week. The results of temperature measurements range from 28.2-290C. Measurement of total suspended solids 0 mg/l. pH measurements ranged from 8.1-8.3. Dissolved oxygen measurements ranged from 4.16-4.27 mg/l. Salinity measurements obtained results of 35 ppt. Ammonia measurements range from 0-1.55 mg/l. Nitrite measurements range from 0.012-0.026. Measurement of total bacteria obtained <1 X 101 cfu/ml from all samples. Measurement of total vibrio yielded <1 X 101 cfu/ml from all samples. Based on the research that has been done, the results show that water quality is still in the optimal range for pearl oyster (Pinctada maxima) hatchery activities.

One of the parameters that play an important role in the success of vannamei shrimp cultivation is salinity. This study aims to determine the effect of decreasing salinity on the behavior and stress response of vannamei shrimp. The test animals used were vannamei shrimp, which were in logs with an average weight of 4.6 – 6.3g. This study used a completely randomized design (CRD) with different salinity reduction treatments in each maintenance medium, namely Treatment A without decreasing salinity, Treatment B decreasing salinity 2 ppt per 6 hours for 24 hours, Treatment C decreasing salinity 2 ppt per 4 hours for 24 hours, Treatment D decreased salinity 2 ppt per 2 hours for 24 hours, each treatment was repeated 3 times. Blood glucose was measured after the decrease in salinity and on the last day of the study. Blood glucose collection was carried out at the fifth swimming leg on white shrimp using a 1 ml syringe that had been rinsed using Na Citrate with the aim that the blood glucose taken did not clot quickly. The results showed a decrease in salinity caused by shrimp stress. The concentration of vannamei shrimp blood glucose increased (13.66 – 52.37mg/dl). Treatment D was the best glucose concentration to suppress blood glucose concentrations (13.66mg/dl). Based on the data analysis of blood glucose concentration (p<0.05) it continued with the real difference test. Vannamei shrimp behavior during salinity reduction showed a response that was not different from all treatments. Salinity 6 ppt is good salinity in the process of suppressing blood glucose concentrations when changes in water salinity occur.

The groove planting system (GPS) is one of the modifications in the plant planting system on ex-limestone mining land. The method used in the implementation of the GPS is to create a basin in the form of an elongated groove on the ex-limestone mining land that has not been reclaimed. Tectona grandis can be grown on less fertile land. This is even recommended by the government, where forest areas were set for planting with teak limited to places that are less fertile and steep. The growth of a plant can be influenced by environmental factors and genetic factors. The interaction between these two factors will determine the growth of a plant. The purpose of this study was to analyze the effectiveness of the Groove planting system (GPS) on the growth of teak (Tectona grandis) in limestone ex-mining areas. The method in this research was an experimental method that was carried out in the former limestone quarry of PT Semen Indonesia in 2020. The results showed that the growth of teak seen from the parameters of plant height, bar chart, leaf number, and leaf color increased. For example, leaf color with a conventional system has a scale of 3 with a GPS scale of 5. Conclusion The GPS method is very effective for the growth of teak (Tectona grandis) because there is an increase in growth and color scale in terms of plant height, stem diameter, number of leaves, and leaf color parameters.

The method used in the implementation of the GPS is to create a basin in the form of an elongated groove on the ex-limestone mining land that has not been reclaimed. Tectona grandis can be grown on less fertile land. This is even recommended by the government, where forest areas were set for planting with teak limited to places that are less fertile and steep. The growth of a plant can be influenced by environmental factors and genetic factors. The interaction between these two factors will determine the growth of a plant. The purpose of this study was to analyze the effectiveness of the Groove planting system (GPS) on the growth of teak (Tectona grandis) in limestone ex-mining areas.

The aims of this study were to determine clinical symptoms, mortality, prevalence, and histopathology of Cantang hybrid grouper fish infected with Oodinium sp. on the Cantang. The study was conducted by direct observation of clinical symptoms, calculating the number of fish mortality, and measuring the quality of water in the tank using the Cantang. While histopathology was conducted in the laboratory using 10 samples of sick fish with an average total length of 10.6 ± 0.69 cm and a weight of 18.6 ± 1.77 g. The results showed that the fish seen swimming weakly on the surface of the water near aeration or standing still at the bottom of the tub, decreased appetite, had pale or darker body color, and were thin. Observation of skin and gill mucus under a microscope showed the presence of ectoparasites Oodinium sp. in massive quantities in almost every gill sheet. The mortality of fish infected with Oodinium sp. in the Cantang of 26.84±3.9%, with a prevalence of 49.59%. Histopathologically the gill lamellae of fish infected with Oodinium sp. shows the occurrence of hyperplasia which causes the union of several gill lamellae.
