Abstract

Macrobrachium is one of prawn genera which has largest species number in family Palaemonidae, with some species of this genus being important commodity in aquaculture. Morphological characters for identification of this genus depend on environmental condition, growth phase, sex, and social dominance. This makes morphological identification on this genus quite difficult and tricky. Alternative approaches are required for better methods of Macrobrachium identification. DNA barcoding using 16S mitochondrial rRNA appears to be one promising method for Macrobrachium identification. This research aims to identify Macrobrachium from Tegenungan Waterfall using morphological and molecular analysis. Samples were taken from 4 sampling sites beneath the waterfall. All specimens were identified using morphological methods according to Holthuis (1950) dan Short (2004). Specimen CR 07a and CR 10 were identified using molecular method. The molecular analysis utilized 16Sar as forward primer and 16Sbr as reverse primer. From 11 specimens, 10 were identified as Macrobrachium. Specimen CR 07a was identified morphologically as M. horstii. According to BLAST analysis, specimen CR 10 was recognized as M. horstii with similarity up to 99% to GenBank specimens (JF310718.1 dan FM986616.1). Specimen CR 07a only reach 97% similariry to both GenBank specimens. Genetic distance analysis between specimen CR 07a and CR 10 assumed high genetic diversity, or even cryptic species indication in M. horstii population of Tegenungan Waterfall.

Abstract

The spangled gudgeon (Ophiocara porocephala Valenciennes,1837) is one of the fish that live in the waters of Belawan and has important economic value to the community. But lately the wild population continues to decline due to factors that supposedly over fishing, waters pollution and habitat degradation. Cultivation effort is one of the solutions to keep the preserved and decrease arrests in nature. The study of associated cultivation efforts need to be made through research. The purpose of this research is to know the frequency of feeding the shrimp kecepe (Acentes japonicus) the right against the growth of absolute spangled gudgeon fish. The benefits of research as the basis for the management and preservation of fish decreased as well as the increasingly Spangled Gudgeon fish efforts do local fish conservation in Belawan Rivers. Results of the study showed the average length of the highest absolute growth was at the treatment D (1.10 cm), followed the treatment C (0.90 cm), treatment B (0.80 cm), and the lowest at the treatment A (0.73 cm). Variansi analysis results indicate that the Fh (8 **) > 0.05 Ft (4.07) means the treatment of natural feeding shrimp kecepe very real influence (highly significant) against the growth of the absolute length of the juvenile spangled gudgeon.

Abstract

Pepper is a commodity of high economic value, but the production is still low due to the use of seeds that are not qualified. The use of seedling from vegetative propagation is the best way to ensure the quality of the seed production. Pepper has been comemercially propaged by rooting of cuttings. To induce roooting in cuttings, use of growth regulators can stimulate root growth. This research was conducted at Teaching and Research Farm, Faculty of Agriculture, Jambi University, in order to find the suitable type of PGR to stimulate pepper root growth. The experimental design used was Completely Randomized Design with one factor plant regulator consisted of seven treatments, Rootone-F 12.5 g /l, coconut water concentration 25%, cow urine concentration 25%, extract of green bean sprouts + 25% moringa leaf extract, 25 % of young corn seed extract + 25% moringa leaf extract, 25% of bamboo shoot extract and 25% of hump banana extract. The observed variables were live crop percentage, percentage of cuttings sprouted, root cutting percentage, shoot length, shoot diameter, root length, dried shoot weight and root dry weight. The results of this study indicate that synthetic plant growth regulators and natural plant growth regulators have a significant effect on the growth of pepper cuttings. The natural plant growth regulator of coconut water with concentration of 25% can increase the growth of pepper cuttings.
