Abstract

This study was aimed to analyze the prospects of development of the This research was aimed to analyze the relationship between plankton abundance and morphometric growth of Mud Clam (Polymesoda erosa). The study was located in an idle brackish water pond in Mahakam Delta, by culturing Polymesoda erosa in small scale. Grouping random design was applied for sampling. Treatment was divided into factor A and B. Factor A is related to shell size: size I (40 – 60,99 mm), II (61 – 80,99 mm) and size III (81 – 100 mm). Factor B is indicating to study location with vegetation (Rhizophora sp) and no vegetation. In order to analyze plankton abundance, a quantitative descriptive analysis was applied, in addition of ANOVA test to analyze the growth. The result indicated that between two study ponds is different. The number of plankton per liter water from vegetated pond has more plankton individual than the sample from non-vegetated pond. The applied treatment on study ponds and shell size determined the morphometric growth and biometric. The growth of shell length is faster than that on height and thickness. The growth of mud clam in vegetated ponds relatively better that the pond without vegetation.

Abstract

Heavy metals are compounds that can affect the quality of a waters. Various kinds and types of heavy metals that enter and settle in sediments can cause diversity to decrease to the extinction of organisms in the waters. This study was aimed to determine the content of Cd, Pb, and Cu accumulated in water, substrate, and gastropods obtained from Kersik Village, Kutai Kartanegara Regency, East Kalimantan. Samples of water, substrate, and gastropods were collected from 4 stations with 3 repetitions. Water samples, substrates, and gastropods were analyzed using AAS. Concentration ranges of Cd, Pb, and Cu in water were 0.003 - 0.011 mg/L; 0.161 - 0.731 mg/L; and 0.007 - 0.009 mg/L, respectively. The concentration ranges of Cd, Pb, and Cu on the substrate were 0.021 - 0.182 mg/kg; 19.5 - 31.12 mg/kg; and 14.29 - 15.47 mg/kg, respectively. In gastropods, the range of Cd concentrations was 0.509 - 0.675 mg/kg, while for Pb and Cu were 15.96 - 21.52 mg/kg and 57.78 - 92.4 mg/kg, respectively. The concentration of Pb in gastropods at all stations has exceeded the quality standard based on SNI-7387-2009, while the concentration of Cu in gastropods at all stations has also exceeded the quality standard based on BPOM No.03725/B/SK/89. Bioconcentration Factor (BCF) of organisms to sediment (BCFo-s), shows the ability to accumulate Cu in Gastropods which is higher than Cd and Pb. Bioconcentration Factor (BCF) analysis of organisms to water (BCFo-w), showed that the accumulation of Cd, Pb, and Cu were in the low, medium, to high categories. The average comparison of concentrations of the three heavy metals at each observation station was not significantly different (sig. > 0.05).

Abstract

Tilapia is one type of freshwater fish that has high economic value. With the increasing demand by the community, tilapia is cultivated in a semi-intensive system so that bacterial diseases caused by Aeromonas hydrophila arise. One way to treat disease in fish safely is the use of lactic acid bacteria. The purpose of this study was to examine the isolates of lactic acid bacteria in controlling diseases caused by Aeromonas hydrophila in tilapia. This study used a completely randomized design experimental method with 4 treatments and 3 replications. The treatments consisted of feed mixed with Phosphate Buffered Saline (PBS), Enterococcus faecalis isolate, Lactobacillus plantarum isolate and Lactococcus lactis isolate at a dose of 0.1 mL/g of feed at a concentration of 106 CFU/mL and mixed with 0.1 mL of egg white. The results showed that the treatment with lactic acid bacteria affected the condition of clinical symptoms and anatomical pathology of tilapia, but was better than the control treatment. The feed mixed with lactic acid bacteria also had an effect on increasing the immune response and showed higher survival than the control treatment. The condition of water quality in the rearing media showed the normal range for the life of tilapia.

Abstract

Relatively higher density at tree level was Sonneratia alba, Rhizophora mucronata at sapling and seedling level. The highest relative frequency at the tree level was Sonneratia alba, Rhizophora mucronata at the sapling and seedling level. The highest relative dominance at the tree level was Sonneratia alba, Rhizophora mucronata at the sapling and seedling level. The high mastery of these two types is influenced by environmental factors that support growth. Judging from the Important Value Index of the Coastal Mangrove Park area for the tree level it is Sonneratia alba and at the sapling and seedling level Rhizophora mucronata is dominant. In terms of using the Tourism Suitability Index for the mangrove tourism category, the coastal-free mangrove park area is categorized as appropriate (S2). Based on direct observations, the conditions in the Coastal Mangrove Park area are suitable for ecotourism activities, but it is still necessary to develop sustainable areas and manage the area sustainably. Judging by using the carrying capacity of the area, the area of beach-based mangrove tourism parks in the category of mangrove tourism is 104 people per day, to maintain a mangrove ecosystem in order to remain sustainable it is necessary to know the carrying capacity of an area so that the implementation of visitor restrictions can be estimated for the purpose of keeping the ecotourism area sustainable.

Abstract

This research was conducted to determine the effect of inulin on the efficiency of feed utilization and the hematological parameters of red tilapia. This study used a completely randomized design (CRD), with 4 treatments and 3 replications. The doses of inulin used in the treatment were 0,00 g/kg, 1,00 g/kg, 2,00 g/kg and 4,00 g/kg. Tilapia with body length of 6,00-6,50 cm and weight of 4,00-4,50 g were reared in a plastic container with a volume of 40 l of water in a semi-closed water recirculation system for 30 days. Fish were fed with treatment using the at satiation method with a frequency of 3 times a day. The results showed that the administration of inulin had no effect on the efficiency of feed utilization (p>0,05), but gave the best value on hemoglobin levels, hematocrit levels, total erythrocytes, total leukocytes, lymphocyte levels, monocyte levels, and neutrophil levels at dose 2,00 g/kg (p<0,05).
