Guppy Fish (Poecilia reticulata) Behavior and Growth Are Affected by Variations in Light Color

This study aims to determine the effect of different colors of light on the behavior and growth of guppy fish (Poecilia reticulata). This research was conducted experimentally using a completely randomized design (CRD) with four treatments and five replications. The treatment used was treatment A with a white light color, treatment B with a red light color, treatment C with a yellow light color, and treatment D with a blue light color. The parameters observed were growth in absolute weight, fish behavior, and water quality (temperature and pH). Data analysis with One Way Anova and further test with LSD using SPSS 25. Based on the statistical hypothesis test with One Way ANOVA showed F count (3.828) > F table (3.24) 5% level for guppy fish growth parameters so that the results are the effect of different light colors on the growth of guppy fish in each treatment. Fish behavior in all treatments gave a positive phototaxis response. The quality of the water in the experimental medium was within acceptable limits for guppy fish cultivation, 26-28°C for water temperature and 7 for the degree of acidity (pH) of water.

Rangsangan Warna Cahaya terhadap Prosentase Karkas Ayam Kampung Super

The purpose of the study was to determine the effect of giving different colors of light on carcass percentage and carcass weight in Kampung Super chickens. The research design used was a completely randomized design (CRD). A total of 80 Kampung Super chickens were used in this study. The research treatments were P1 (white light color), P2 (yellow light color), P3 (green light color), P4 (red light color), P5 (blue light color). The results of the study of the highest carcass presentation were found in the treatment that was given red light with an average value of 62.455%. The highest carcass weight was found in the same treatment, which was given a red light with an average value of 674.75 g/head. The provision of different light colors did not have a significant effect on the carcass percentage and carcass weight of the finisher phase super free-range chicken.

Thermal spectrum characteristics of blue light flare irradiation and its impact on surroundings biotic and abiotic environment

A recent modification of flare light irradiation with a high-pressure system in blue light color has been causing performance improvement of the flare light so that it is more invisible at the daylight time and in the night as well. It has been reducing social complaints. Field observation was conducted in 2011 in Jambi. Blue light showed very low irradiation, illumination, quantum value and ultraviolet at the soil surface. Its surrounding thermal spectrum was recorded with an infrared thermal imager and its impact on ambient and soil temperature was found as insignificant. There was also found that latex production and understory vegetation biodiversity at the distance of 225-800 m from the radiation source was not affected by the irradiation
