Abstract

The role of lake waters in supporting people's lives in a broad sense is largely determined by the level of lake productivity, one of which is primary productivity. The primary productivity of the lake can be seen from the abundance and diversity of phytoplankton which are the basic components in the food chain system in waters. The purpose of this study was to determine the level of primary productivity and abundance of phytoplankton. The bottle-dark-bottle-light method was used to determine the photosynthetic rate and respiration of phytoplankton. Gross photosynthesis (GP = dirty photosynthesis) is obtained by subtracting the dissolved oxygen content in the dark bottle from the dissolved oxygen content in the light bottle, after being subjected to lighting (incubation) for several hours. Result the highest abundance is at station II. The uniformity index shows that for station 3 it is the lowest category. The results of the calculation of the phytoplankton dominance index have a value that is inversely proportional to diversity. Based on the category, the index value for the three stations is categorized as low dominance. Water quality parameters measured include dissolved oxygen (DO), degree of acidity (pH), temperature, brightness, and turbidity. Based on all measurements and several aspects of conditions that occur in the waters of Lake Tamblingan, it is still classified as normal and good enough for the continuation of aquatic life. The determinant of the primary productivity among them was pH, temperature, turbidity, and brightness.

Abstract

Chronic apical periodontitis is an inflammatory disease that causes periodontal tissue destruction and forms chronic lesions. This study aims to prove that the administration of green meniran leaf ethanol extract can affect the kidney histopathology of chronic apical periodontitis Wistar rats. This study used a randomized posttest only control group design with four treatment groups and twelve replications of three sub-groups according to the time of application of the medicament paste, namely the 7th, 14th, and 21st days so that 48 Wistar rats were used. The treatment group consisted of negative control (K1), only injected with disease-causing bacteria. The positive control group was given 2% Calcium Hydroxide and Chlorhexidine digluconate. Treatment group 1(P1) was given calcium hydroxide and 10% green meniran leaf ethanol extract, and treatment group 2(P2) was given calcium hydroxide, 2% chlorhexidine digluconate, and 10% green meniran leaf ethanol extract. All samples were male Wistar rats with a weight ranging from 300-350 grams. The variables observed were congestion and necrosis with a score of 0 (normal); 1 (focal); 2 (multifocal); 3 (diffuse). The data were analyzed using the Kruskal-Wallis non-parametric statistical test and if it showed a significant effect, it was continued with the Mann-Whitney test. The results of the Kruskal-Wallis test showed that in the K2, P1, and P2 treatments, there was a significant difference (P<0.05) in the category of congestion and necrosis of the histopathological changes of the kidneys. The results of this study indicate that the ethanol extract of green meniran leaves which has a function as an antioxidant can repair kidney damage caused by free radicals in chronic apical periodontitis conditions

Abstract

Lake Batur has the potential to be a fishery resource that has not been explored and even very little attention from the community and the government so that this resource can be developed optimally. The current condition of lake Batur waters tends to change either naturally or annually or changes due to community activities around the lake. This study aims to determine the feasibility of lake Batur waters as a fish farming business field for the freshwater floating net cage system. Water samples to be tested for water quality and plankton were obtained directly at Lake Batur. The results of plankton abundance at each station were received, at station I (2.070 ind/l), station II (1.477 ind/l), station III (6.975 ind/l), and station IV (2.617 ind/l), station V (2.902 ind/l). The parameters observed are water quality parameters in the form of brightness, temperature, pH, DO, Nitrates, Nitrites, and plankton abundance in Lake Batur Kintamani, Bangli. The results of research on the quality parameters at each station showed different values. The brightness parameters at 5 stations have values in the range of 246-480 cm, temperatures 26-28.3 °C, pH 7.5-8.3, DO 7.1-8.3 mg/L, Nitrates 0.36-0.66 ppm, and Nitrites 0.02-0.04. brightness.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Hybrid grouper is a variety of grouper that has become increasingly popular in recent years. The development of grouper cultured in Indonesia utilizing the Recirculating Aquaculture System (RAS) is currently underway; nevertheless, fish cultured in the RAS system continue to struggle with infectious diseases, one of which is VNN (viral nervous necrosis) infection caused by piscine betanodavirus. The purpose of this study was to know the clinical sign, mortality, and histopathology of cantang grouper (Epinephelus fuscoguttatus x E. lanceolatus) infected with VNN in RAS. Fish samples were obtained from the hatchery using RAS. This research uses a mixed methods approach and the type of research used is exploratory research. The parameters observed were clinical signs, mortality, and histopathology. Water quality, including temperature, DO, salinity, and pH at the time of VNN infection, was used as secondary data. The results showed that clinical signs of sick fish were weakness, staying at the bottom of the rearing tank, decreased appetite, swimming with the stomach facing up and the body dark in color. Fish mortality occurred for ± 10 days with a peak of mortality reaching 26.86 ± 7.45% on day 9 from initial signs. Histopathology result, diseased fish showed vacuolization in the brain and retina of the eye.
