Abstract

Abstrak: Ikan karper merupakan ikan yang penting dalam memberi kontribusi terhadap akuakultur dunia. Salah satu kendala dalam budidaya ikan karper adalah penyakit Tanaman ketapang merupakan tanaman yang dapat berfungsi untuk medis. Penggunaan ragi Saccharomyces cerevisiae dapat meningkatkan sistem imun. Penelitian bertujuan untuk mengetahui pengaruh ekstrak daun ketapang (Terminalia cattapa) dan ragi terhadap prevalensi dan intensitas ektoparasit pada ikan karper (Cyprinus carpio). Penelitian menggunakan metode eksperimental dengan 4 perlakuan yaitu, P1 : daun ketapang 1,2 g/L; P2 : daun ketapang 1,2 g/L + 2,75 g ragi dalam 16 L air; P3 : daun ketapang 1,2 g/L + 5,5 g ragi dalam 16 L air; dan P4 : daun ketapang 1,2 g/l  + 11 g ragi dalam 16 L air. Data penelitian dianalisa dengan menggunakan analisa sidik ragam dan analisa regresi linier. Hasil penelitian menunjukkan bahwa penambahan ragi dan bubuk daun ketapang tidak berpengaruh nyata terhadap prevalensi dan intensitas ektoparasit pada ikan karper. Berdasar hasil analisa regresi menunjukkan bahwa penambahan bubuk daun ketapang dan ragi mampu meningkatkan kelangsungan hidup ikan karper. Kata kunci: ikan karper, ketapang, ragi, ektoparasitAbstract: Carp is an important fish in contributing to world culture. One of the obstacles in carp cultivation is the disease. Cattapa plants can function for medical purposes. The use of yeast can improve the immune system. The study aimed to determine the effect of cattapa leaf extract (Terminalia cattapa) and yeast on the prevalence and intensity of ectoparasites in carp (Cyprinus carpio). The study used an experimental method with 4 treatments, namely, P1: cattapa leaves 1.2 g / L; P2: cattapa leaves 1.2 g / L + 2.75 g yeast in 16 L water; P3: cattapa leaves 1.2 g / L + 5.5 g yeast in 16 L water; and P4: cattapa leaves 1.2 g / l + 11 g of yeast in 16 L of water. The research data was analyzed using variance analysis and linear regression analysis. The results showed that the addition of yeast and leaf powder of cattapa had no effect on the prevalence and intensity of ectoparasites in carp. Based on the results of the regression analysis, it was found that the filling of cattapa and yeast leaf powder was able to increase the survival of carp.Keywords: carp, cattapa, yeast, ectoparasite

Abstract

The purpose of this research is to examine the use of mathematics in the field of fisheries. This literature review research examines scientific articles or research journals consisting of 7 national journals and 5 international journals. The study is limited to taking the results of previous research which includes results related to the use of mathematics in the field of fisheries. The results of the study show that mathematics in the field of fisheries is proven to be widely used, both in the use of mathematics on basic matters or entrenched habits (ethnomathematics) such as counting the number of fish, calculating feed, calculating the area of ponds, calculating buying and selling, weighing seeds and feed and predicting schedules. harvest and others. The use of more specific mathematics, for example ethnomathematics in the cultivation process by Indramayu shrimp cultivators, application of mathematical modeling to determine the growth in weight of a fish species, construction and dynamic analysis of mathematical models of fishing systems (a case study of the Nusantara Brondong fishing port), mathematics as a tool for efficient fisheries management and economic growth in Gashua, application of optimum control on fish harvesting models in non-reserved zones taking into account reserve zones, mathematical modeling applied to renewable fisheries management, mathematical modeling of predator-prey fisheries in polluted water ecosystems, mathematical modeling applied to sustainable management of marine resources, marine capture fisheries production, rainfall, and sea surface temperature with vector autoregressive (VAR) models, mathematical models of fish harvesting with selective harvest policies, and least square method mathematical models (least square method) on body shape fishing boat

Abstract

Tiger grouper is a type of fish whose habitat is in waters, especially rocky waters with a water depth of about 0.5-3 cm (young) and 7-40 cm (adults) from the surface. Tiger grouper is caught with bottom line and net. The purpose of this study was to determine growth parameters regarding growth patterns and condition factors, and to determine reproductive biology parameters regarding gonads, eggs and ficundity of tiger grouper. This study used a dependent descriptive survey method which was carried out in Labangka waters, Sumbawa Regency. Data analysis used simple regression analysis. The results of data processing showed a positive LWR (length weight relationship) pattern (ln W = -a + b ln L) and a hyper-allometric growth pattern (b>3) with a value of b = 3.6. While the value of the condition factor is K average = 1.41 where the K value obtained indicates that the body of the grouper fish in Labangka is less flat and fleshy and is still in its infancy. The results of fecundity data processing produced 675,073.34 eggs/gonads with a gonad weight of 30 g, a gonad length of 8.8 cm and a parent fish weight of 489 g and a length of 29.8 cm

Abstract

The purpose of this study was to determine the effect of different weights and media on the growth rate of Infusoria (Paramecium sp). The method used in this study is an experimental method using a completely randomized design (CRD). The results of the Variety Sidik Analysis (ANASRA) showed that the growth of Infusoria (Paramecium sp) in each treatment was significantly and very significantly different (Significant) where F count > F table 5% (5.795 > 3.68) and (8.765 > 3.68 ), means that the growth rate of Infusoria (Paramecium sp) is different in each treatment or experiment. The highest cell division was on day V (five) with 5,160 cell divisions and an average of 1,720 cells in the A2B1 treatment and the lowest division occurred on day IX (nine), namely 40 cells with an average of 13.4 cells in treatment A1B3. Further test results using the Least Significant Difference (LSD) test showed a significant (significant) difference in the A2B1 and A2B3 treatments (3,563 > 2,940.452), whereas in the A2B1 and A2B2 treatments (2,563,333 < 2,940,452), A2B2 with A2B3 (1000 < 2940.452), A1B1 with A1B2 (2320 < 2940.452), A1B1 with A1B3 (2780 < 2940.452) and A1B2 with A1B3 (460 < 2940.452) this shows no significant difference (non significant

Abstract

Water pH is an important external factor for the success of hatching fish eggs. PH stimulates the chorionase enzyme to be more active, it can soften the egg chorion. The purpose of this study was to determine the optimum pH value for Pangasianodon hypophthalmus hatching eggs. This research was conducted at the Batu Kumbung Fish Seed Installation, Lingsar, West Lombok. The research design used a completely randomized design with 5 treatments and 3 replications. Treatments are P1 (pH6), P2 (pH7), P3 (pH8), P4 (pH9) and P5 (pH10). The results showed that the different pH values of the water had a significant effect on the hatching percentage and the survival of Siamese catfish larvae. The highest hatching percentage (77.54%) was in the pH 8 treatment, the highest Siamese catfish larvae survival rate (95.12%) was in the pH 7 treatment which was not significantly different from pH 8 which produced 94.54%.

Abstract

The research aims to know the cross results of a better growth rate than the uncrossed missed. The cross is measured in units of weight (gram) and length (cm) of fish, Survival Rate (SR) and Feed Conversion Ratio (FCR). The design used in this study is the group Random Plan (RAK) with a replay of 3 times and analyzed using a print analysis of variance (ANOVA) at a real level of 0.05 with a confidence interval of 95%. Based on the results of the study gained that the results of the cruciation ? Sangkuriang >< ? Masamo has the highest growth value weighing 302, 0a g/tail and length 31, 2a cm/tail For 60 days of maintenance and Feed Conversion Ratio (FCR) is best of 0.9 different real (p < 0.05) Other uncrossed and missed results.
