Abstract

The damage rate of mangrove forests in Indonesia is considered as the fastest and largest in the world. The reduced density of mangroves can be influenced by the water quality and the organic matter content around the mangrove ecosystem, causing changes in the mangrove leaves both in the shape of the length and width. This study was conducted in the mangrove ecosystem in the western part of Dumai City, with the aim of determining the morphometric size of the leaves of Rhizophora apiculata and its relationship with the content of organic matter in the sediment. The method used in this study was survey method, where observations and sampling were performed directly in the field and some of samples were analyzed in the laboratory. Mangrove density obtained from the research results ranges from 1966.66 - 4700 ind/ha, organic matter content 10.88 -17.21%. The morphometric size of the leaf length varies from 13.03 - 15.05 cm, the leaf width varies from 4.65 - 5.42 cm, and the length of the petiole varies from 1.59 - 1.91 cm. There is no significant relationship between the mangrove leaf morphometric with sediment organic matter in the studied area.

Abstract

This research has been carried out from November to December 2019 at the Laboratory of Parasites and Fish Diseases at the Fisheries and Marine Faculty of Riau University. The aim of the study was to obtain the best dose of mango leaf solution for the treatment of striped catfish (P. hypophthalmus) infected with E. tarda, seen from the erythrocyte picture. The method used was an experiment with a Completely Randomized Design (CRD) of a factor of five treatment levels and replications three times. Test fish used were striped catfish measuring 8-12 cm, with a total of 150 fish. The treatments used for treatment were 1000 ppm, 1200 ppm, 1400 ppm, negative controls (not infected and not treated), and positive controls (infected and not treated). Parameters measured and observed among others; total erythrocytes, hemoglobin levels, hematocrit values, erythrocyte cell morphology and survival rate. The results showed that apple mango leaf solution (M. indica) was able to treat conjoined striped catfish infected with E. tarda by Emmersion method. The best treatment of 1200 ppm is characterized by an average total erythrocyte, mean total erythrocytes 149.33 x 104 cells / mm3, hemoglobin level 9.03 g / dL, hematocrit value 35.67% and the survival of the test fish after treatment is 86.67%. The results of water quality measurements during the study, namely temperature 27.00-27.46 0C, pH 6.1-6.77, dissolved oxygen 3.53-3.87 mg/L, and ammonia 0.02 mg/L.

Abstract

Many of marine ecotourism activities on Nirwana Beach has had a negative impact to the development of seagrass ecosystems. Pressure that occurs on the coastal ecosystem becomes a trigger factor seagrasses to adapt with produce certain compounds for maintain immunity, the name is bioactive compounds. This research was aimed to know toxicity to Artemia salina and phytochemical component of Thalassia hemprichii seagrass from Nirwana Beach by using experimental method. Two seagrass extracts with different solvents have been made in the Marine Chemistry Laboratories for use in toxicity and phytochemical tests. The results of the test are displayed in tabular or graphical form and analyzed descriptively. The results of toxicity testing showed that seagrass had a toxicity level of 446.872 ppm (n-hexane solvent) and 218.183 ppm (methanol solvents), both of extract are toxic to the Artemia salina. Phytochemical testing shows tannin compounds founded in extracts with n-hexane and methanol solvent, alkaloids and triterpenoids compound contained in extracts with methanol solvent

Abstract

Prayang is traditional fishing gear, a prohibition on the use of cantrang fishing gear by the Ministry of Maritime Affairs and Fisheries (KKP) requires an alternative replacement fishing gear, considering that the condition of the Java sea waters is already overfished. The study aims to determine the effect of using different color lights on prayang fishing gear on catches. The research method is an experiment by applying "light fishing" technology. The initial stage of the study was the use of lighting aids with different colors. Based on the results of statistical tests the lamp color treatment had no significant effect, the catch was dominated by white shrimp species for the use of white light and the shrimp continued to prefer green

Abstract

Palembang is the capital city of South Sumatra Province which has special foods which main raw material is fish. Many pempek entrepreneurs use cork fish meat for pempek raw material resulting in abundance of cork fish bone waste, therefore researchers utilize cork fish bone waste as an alternative into raw material in making gelatin. In this study, researchers used several weak acids derived from natural ingredients such as lime extract and starfruit extract and as a comparison researchers used synthetic weak acids namely citric acid in the market. The purpose of this research used several types of acids in the demineralization process to produce better gelatin production. This study used a Completely Randomized Design, with several acid treatments with and consisting of 3 (three) treatment levels, each treatment was repeated 3 times. The treatment in this study was a demineralization process with the addition of citric acid was (A1), lime extract was (A2), and starfruit extract was (A3). The parameters examined in this study include: Gelatin yield, Gelatin acidity (pH), Moisture and Sensory content (color and aroma). Data from proximate observations were analyzed by analysis of variance (ANOVA) and further tested based on the coefficient of diversity. From the results of this study, it was found that the best treatment of using variations in acid was gelatin demineralized using citric acid which produced a yield was 6%, a moisture content was 9.21%, pH 6, the panelist's favorite value of color was 4.3 and aroma 3, 8

Abstract

Sunu grouper fish belongs to the Seranidae family whose pattern of reproduction is anti hermaphrodite protogyny, which is the gonad as an organ that changes the transition from the female to male phase. The aims of this research is to study the growth pattern of Sunu grouper fish and find out the total of female Sunu grouper or male Sunu grouper that caught a lot. This research was conducted at the Port of Kurau Coastal Fisheries, Central Bangka Regency, Bangka Belitung Province from February to March 2020 using a survey method. The results showed that the catch of tiger grouper fish reached 399,94 kg, consist of 283,44 kg or 581 female fish species and 116,50 kg or 69 fish according to male sex. The total number of fish caught during the study was 650 fish with the growth pattern is allometric positif. The results also showed a coefficient of determination (R2) of female groupers 0.938 and a value of determination (R2) of 0.701 in male groupers. Based on the results of research that has been done can conclude the growth pattern of female Sunu grouper is allometric positif with value 3,09 and the growth pattern of male Sunu grouper is allometric positif with value 3,87. The total of Sunu grouper fish catch along research is about 650 fish consist of 581 female grouper fish and 69 male grouper fish.

Abstract

Bamboo clam (Solen lamarckii) is a type of mollusck of the Solenidae family known as “sepahat” by the people around Bengkalis. This study was conducted at Api-Api village waters, Bengkalis Regency in January 2020. This study aims to investigate the fecundity produced by each female of bamboo clam and egg diameter in each phase of maturity gonad stage. This study used survey method and sampling location determined by simple random sampling. Fecundity was calculated using the modificated volumetric method. The result showed, the fecundity of bamboo clam ranged from 290,325-1,902,391 with an average 1,105,285 ±1,074,724 eggs for 50.3-72.8 mm in shell length. Egg diameter ranged between 30-110 μm. Average diameter in each phase of maturity gonad stage, the stage I gonads was 46.7 μm, stage II 65.2 μm, stage III 82.8 μm and stage IV 101 μm
