Abstract

The study aimed to find out the long-standing difference in irradiation to the growth rate of Kappaphycus alvarezii in controlled containers. The method used is experimental. This study used a Complete Randomized Design (RAL) using four (4) treatments with 3 repeats, namely the treatment of P1 control (without irradiation), P2 (8 hours of irradiation), P3 (10-hour irradiation), P4 (12-hour irradiation). The data were analyzed using analysis of variance (ANOVA) at a rate of 5% with a confidence interval of 95% and continued with the Duncan test. In this study, the average results of absolute weight and the highest specific daily growth rate at P4 treatment of 25.67±1.53 gr, 3.30±0.06%, followed by P3 treatment 21±2 gr, 3.11±0.09%, P2 treatment 16±1 gr, 2.87±0.06%, and lowest P1 treatment 12.33±2.08 gr, 2.63±0.15%. The average value of light intensity in each treatment is P1 1053±41.00 lux, P2 1256±27.71 lux, P3 1479±0.58 lux, and P4 1668±34.64 lux. Water quality parameters during maintenance are in the normal limit range for seaweed maintenance. D treatment produces the highest growth value this is because the light is an energy source in the process of photosynthesis, in chlorophyll plants, photosynthesis is the main process determining the rate of growth. The quality and amount of light that enters affects the growth of seaweed. This research concluded that the maintenance of Kappaphycus alvarezii in controlled containers with different irradiation had a significant effect on growth. 12 hours irradiation (P4) gave the best growth with an absolute weight of 16.00 g, and a specific growth rate of 4.06% per day and gave the highest chlorophyll-a value of 2.72 mg/l. Meanwhile, the highest phycoerythrin value was found in (P1) without irradiation, which was 4.58 mg/l.

Abstract

Due to the increasing demand for lobster raw materials, the demand for lobster seeds continues to increase. UD Sari Laut as a lobster farming group is struggling to meet the demand for lobsters due to the limited number of floating net cages (In Indonesian called KJA) for running lobster seed farms. In an intensive lobster farming business, it is estimated that about 70% of production costs come from feed costs. The aim of this activity is to implement waste fishing technology using floating maps to increase the scale of lobster farming and reduce feed purchase costs. The activity method used is the demonstration plot directly with activity partners with activity stages including preparation for the purchase of floating net cages (KJA) and floating maps, group training, coaching, monitoring and evaluation. The result of this activity was the addition of KJA plots to 9 plots, previously only 6 plots giving a positive value to UD Sari Laut. Besides being able to house about 1,350 lobster seeds, with the addition of KJA plots it can also be used for lobster seed nursery operations with a profit of Rp. 2,970,000/month. The results of the garbage floating cards purchasing activity to meet the need for comprehensive lobster culture feed in KJA provides positive value for KUB Cinta Bahari. Where before having a floating card, the growers usually bought waste fish from fishermen around the site. The cost of buying waste fish ranges from Rp. 30,000 - Rp 50,000, depending on the season and the size of the business. So, with the operation of the floating card, the production cost of feed can be reduced. The existence of this floating card provides additional income, selling fish of high commercial value in the market. The conclusion of this activity is that this activity has a positive value for the target group, by increasing the number of floating net cages for the storage and breeding of lobster seeds and the availability of floating card cages.

Abstract

White snapper (Lates calcarifer) is a type of seawater fish that is in great demand by the public. This study aims to determine the 48-hour LC50 value and the effect of using betel leaf extract on the health status of white snapper. This research was conducted in July 2020 which took place at the Sekotong Coastal Aquaculture Development Center (BPBPP), West Lombok Regency, West Nusa Tenggara. This research was conducted using experimental methods. This study used 5 treatments and three replications, to obtain 15 experimental units with doses of 0 ppm, 80 ppm, 90 ppm, 100 ppm and 200 ppm. Data analysis was performed using a linear regression test, namely probit analysis by testing the mortality of tested animals and calculated through statistical data using Microsoft Excel. The higher the betel leaf extract concentration, the higher the number of white snapper seed deaths. This happens because the betel leaf extract contains active antimicrobial compounds, but at high concentrations, it can poison the white snapper seeds. For further research, it is recommended to test the toxicity of betel leaf extract on the mortality of white snapper with variations in water quality.
