Abstract

This study aims to know various types, prevalence, and intensity of ectoparasite on mud crab (Scylla serrata) in mangrove area Wonorejo, Surabaya.  This study used survey method with random sampling to collect the data.  This study was conducted in July-December 2020. Ectoparasite in this study collected by smear method.  In-situ water quality measurement were applied in this study.  Mud crab in this study was obtained from local fisherman that consist of 30 crabs.  There are 3 types of ectoparasite was infected mud crab there are Octolasmis sp. (208 ind), Zoothamnium sp. (93 ind), and Epistylis sp. (116 ind).  Those ectoparasite was found in mud crabs gills.  The highest prevalence was Octolasmis sp. (70%), Epistylis sp. (30%), and Zoothamnium sp. (23%).  The highest intensity was Zoothamnium sp (13.29 ind/crab), Epistylis sp. (12.89 ind/crab), and Octolasmis sp. (9.90 ind/crab).  Based on Ministerial Decree of Ministry Environment and Forestry No. 1 of 2004 water quality in Wonorejo mangrove area was still optimal for life cycle of mud crab with average of temperature is 31.20°C, Dissolved Oxygen 5.53 mg/l, salinity 11 ppt, and pH 7.40.

Abstract

Chitosan synthesized from milkfish (Chanos chanos) scales and tiger shrimp (Panaeus monodon) shells were used as corrosion inhibitors on ASTM A36 steel. Milkfish scales and tiger shrimp shells wastes is extracted into chitosan through deproteination, demineralization and deacetylation process. The yield of milkfish scales and tiger shrimp chitosan was 31,81% and 67,16%, respectively. Corrosion rate testing using weight loss method then calculates inhibition efficiency of each inhibitor. The immersion test of specimens was carried out for four weeks with weight measurements every week. The concentrations used were 0 ppm as negative control; 60 ppm, 500 ppm and 1000 ppm for chitosan inhibitor; and 1000 ppm sodium nitrite as positive control. Inhibition efficiency values ​​produced by milkfish scales chitosan, starting from the first to the fourth week immersion, for concentration of 60 ppm were 43.9%, 46.8%, 48.9%, and 40.8%; for concentration of 500 ppm were 43.6%, 43.3%, 37.8%, and 17.8%; and for concentration of 1000 ppm were 37.5%, 44.9%, 39%, and 21.8%; while for tiger shrimp shells chitosan for concentration of 60 ppm were 37.6%, 51%, 34.6%, and 28.5%; for concentration of 500 ppm were 57.7%, 38.2%, 37.7%, and 19.6%; and for concentration of 1000 ppm were 48.6%, 41.2%, 37%, and 21.3%. Comparison of inhibition efficiency between chitosan from milkfish scales and tiger shrimp shells based on the statistical analysis One Way ANOVA resulted in a sig >0.05 which indicates a similarity in the efficiency value of chitosan from milkfish scales and tiger shrimp shells.

Abstract

This study aims to find out the activities of local sea cucumber methanol extract (Phyllophorus sp.) as a natural antifouling against macrofouler Nerita sp. This study uses experimental methods laboratory. Laboratory-scale data collection is carried out by observation of biota paste activities fouling on the aquarium (antifouling rate) as well as its regaining rate. This research uses research design complete random design (RAL) with three repetitions. Local sea cucumber methanol extract (Phyllophorus sp.) contains bioactive compounds such as saponins, alkaloids, tannins, steroids and phenolics. Methanol Extract local sea cucumber (Phyllophorus sp.) affects the antifouling rate by reducing the Nerita sp. macrofouler paste rate with increasing concentration. It's the same thing,occurs where the increasing concentration of local sea cucumber methanol extract (Phyllophorus sp.) provides a significant decrease in Nerita sp. macrofouler regaining capability. The results lethal concentration 50 or LC50 obtained a value of 185.18. This means the concentration of the extract sea cucumber (Phyllophorus sp.) is deadly 50% of all biota test at a concentration of 185.18 mg/ml. Based on antifouling rate analysis and regaining rate it is known that the concentration of the most effective that can be used as an antifouling is a concentration of 75 mg/ml. This is because a concentration of 75 mg/ml of local sea cucumber methanol extract (Phyllophorus sp.) can already inhibit paste macrofouler Nerita sp. The concentration of 75 mg/ml also has a large regaining rate of 85%.

Abstract

This study aims to find the value of the fastness test of the natural dye of mangrove leaves (Bruguiera gymnorrhiza). This research was conducted in June-November 2020. This research used descriptive and experimental methods. The samples used were cotton, rayon, and sateen fabrics. The experimental results showed the addition of fixator tunjung (FeSO4) capable of binding dye mangrove leaves Bruguiera gymnorrhiza that give color to the fabric fibers. The result of the coloring is brownish yellow. The results of the color fastness value in hot water are influenced by the difference in ΔE (colorfastness), cotton fabrics have a range of values ​​between the medium category (5.1-5.94), the medium-large category rayon cloth (5.09-9.06 ), medium category sateen (3.65-4.35). The results of the color fastness value in cold water are influenced by the difference in ΔE (colorfastness), cotton fabrics have a range of values ​​between the small and medium categories (1.96-3.68), rayon fabrics in the small category (2.83-3.9 ), the small category of sateen fabrics (1.54-2.76).

Abstract

Red tilapia (Oreochromis niloticus) has its advantages compared to other cultivated fish. Namely, it can proliferate, is easy to breed, and is efficient for feeding. Besides, these fish can also tolerate changes in the aquatic environment. With these advantages, this fish is increasingly popular among cultivators. The need for tilapia fish seeds is increasing every year. The UPT of Freshwater Aquaculture Fisheries (PBAT) of Pasuruan Regency is one of the superior seed supply units for fisheries in East Java. The superior commodity is tilapia fish seeds. The purpose of this research is to know hatchery techniques for Red Tilapia (Oreochromis niloticus) at UPT PBAT Pasuruan Regency. The research was carried out directly through active participation in all Red Tilapia hatchery activities. The results are: Red tilapia hatchery at UPT PBAT Pasuruan Regency, uses natural spawning techniques with a male to female ratio of 1: 3. The spawning period is 21 days until harvest with two types of broodstocks, namely mature sires (2500-2700gr) and novice sires (300-500gr); The hatchery technique stages are media preparation, parent selection, spawning, larva harvesting, larva treatment, nursery, and seed harvesting; Water quality is still within the quality standard set by PP. 82 of 2001 with details of the average temperature of 29C, DO 7.7 mg / L, pH 8.325, and water depth of 50 cm.
