Abstract

Comet fish (Carassius auratus) is a type of freshwater ornamental fish with a high selling value due to its unique body shape and bright colour. The purpose of this study was to evaluate the effect of different LED (Light Emitting Diode) light colours on colour brightness, growth, and survival of comet fish. This study applies an experimental approach with an experimental design in the form of a completely randomized design (CRD) and consists of 5 light treatments and 3 replications, namely A (room light), B (white LED), C (blue LED), D (green LED), and E (red LED). The results showed that LED light treatment had a significant effect on the colour quality and feed efficiency, but did not significantly affect the growth and survival of comet fish. The best colour quality was found in treatment E (red LED) with an increase in the TCF (Toca Color Finder) score of 6.22 and colour performance on the back by 80.80%, pectoral fin colour by 64.91%, and tail fin by 71 .18%. The best feed efficiency was obtained in treatment C (blue LED) with a feed efficiency value of 57.48%. The behavioural responses of comet fish did not make any difference between each LED treatment. The water quality of the comet fish rearing media has a temperature value ranging from 25.70 – 29.20 C. The pH value ranges from 7.29 to 8.50. Meanwhile, dissolved oxygen ranges from 8.00 – 12.20 mg/L.

Abstract

Kappaphycus alvarezii is used in industry as a food ingredient, a source of hydrocolloids, cosmetics, food additives, animal feed, fertilizers, biofuels, and medicinal ingredients. K.alvarezii is cultivated in several areas in Indonesia, including on the island of Lombok. The production of K.alvarezii is related to its growth and it is related to its phytohormones. K.alvarezii cultivated in Lombok is currently not known for its composition and amount of phytohormones. The content of phytohormones at different planting ages is of course different. The purpose of this study was to determine the number of phytohormones in seaweed K. alvarezii at different planting ages. This study was conducted in Ekas Bay, Lombok, Nusa Tenggara Barat from June to December 2020. The study used experimental methods and descriptive data analysis. The results of this study explain that currently cultivated K. alvarezii contains cytokinins, auxins, and gibberellins. Cytokinins obtained on the 9th day of planting were 11.62 ppm and increased on the 18th day to 12.34 ppm. At the next planting age, it continued to decrease on the 27th day to 11.43 ppm and at harvest time, the 45th day of 10.69 ppm. Auxin detected in the seeds used was 644.93 ppm, on the 27th day of 14.27 ppm, on the 36th day of 1078.25 ppm. Giberilin was detected on the 9th day at 0.49 ppm. This study concluded that K. alvarezii at different planting ages had different phytohormones content.

Abstract

This study aims to analyze the effect of different cross-sectional areas of recirculation systems on water quality in tilapia (Oreochromis niloticus) rearing. The method used is an experimental method with a completely randomized design (CRD), 4 treatments and 3 replications each. The treatments are P0 (conventional), P1 (2 cross-sectional units with an area of ​​1,087 cm2), P2 (4 section units with an area of ​​2,174 cm2), P3 (6 section units with an area of ​​3,261 cm2). Each treatment used the same filter, namely cotton, zeolite, pumice stone, and bio balls. The results of the research the highest absolute weight growth was obtained in the P3 treatment with an average value of 4.56 g and followed respectively P2 4.38 g, P2 3.03, P0 2.59 g. The highest absolute length growth rate was obtained in treatment P3 2.71 cm, P2 of 2.54 cm, P1 of 1.87 cm, and the lowest absolute length was found in treatment P0 of 1.62 cm. The highest feed conversion value was at P0 at 3.91, followed by P1 at 2.84, P2 at 2.06, and the lowest at P3 at 1.94. The highest survival value was P3 of 85.00, P2 r 83.33, P1 73.33 and the lowest was P0 of 55.00. The highest diversity coefficient value was obtained in treatment P0 of 17.58, followed respectively by treatment P1 of 16.05, P2 of 12.91 and the lowest coefficient of diversity found in treatment P3 of 12.69. The conclusion of this study is the use of different recirculation cross-sectional areas has a significant effect on absolute weight growth, absolute length growth, feed conversion ratio, survival, and water quality. The recirculation cross-sectional area in P3 treatment with a cross-sectional area of 3.261 cm2 gave good results for the survival of tilapia.

Abstract

Sargassum sp. is seaweed from the group of brown algae belonging to the Phaecophyceae class that can be found in Indonesian. Sargassum sp. contains polysaccharides in the form of alginate which can be used as raw materials and additives in the food, drug, and cosmetic industries. The aim of this study was to analyze the growth of Sargassum sp. which are cultivated with different seed weights on the floating rafts. The research was conducted from November 2020 to March 2021 in Ekas Bay, East Lombok, West Nusa Tenggara. The research method used is an experimental method using a completely randomized design (CRD) consisting of five treatments with four replications. The treatments were differences in the weight of the initial seeds used, namely treatment A (25 g), B (50 g), C (100 g), D (150 g), and E (200 g). Sargassum sp. Cultivation was carried out for a month. The results were the highest absolute weight was in treatment E with 550 g and the lowest occurred in A with 262.5 g. The highest specific growth was in treatment A with 8.13%/day and the lowest was in E with 4.4%/day. This study concluded that different seedling weights had a significant effect on the growth of Sargassum sp. cultivated using the floating raft method.

Abstract

Gouramy (Osphronemus gouramy) is a freshwater fishery commodity with a large enough demand and a fairly expensive price compared to other freshwater fish. The purpose of this study was to determine the effect of temperature on larval quality and growth of gouramy fry. The research method used is an experimental method using a Completely Randomized Design (CRD) consisting of two treatments of water media temperature, namely 1) Treatment A = The temperature of the media follows room temperature (control treatment), and 2) Treatment B = The temperature of the medium was set constant at a temperature of 30ᵒC. Each treatment was repeated six times to obtain 12 experimental units. Research parameter data were analyzed statistically using variance (ANOVA) at a 95% confidence level using the t-test. The results showed that the degree of hatching of gouramy eggs, larval size, absolute growth, relative growth, daily specific growth rate and survival rate of gouramy larvae at room temperature and 30°C were 90.38% and 98, respectively. 76%; 0.54 cm and 0.66 cm; 0.86 cm and 0.87 cm; 157.52% and 133.26%; 3.99% and 3.58%; and 74.78% and 91.22%. The study concluded that eggs incubated at room temperature (25-28°C) and 30°C gave significantly different effects on hatching rates and post-hatching larvae size. Larval rearing at room temperature and 30°C gave no significant effect on absolute growth but significantly different on relative growth, daily specific growth rate and survival rate
