Abstract

Kale (Brassica oleracea) contains some nutritional values like: vitamin C, pro vitamin A (carotenoids), and some compound belong to polyphenol are flavonoids that benefit to its consumer for the growth and health of the body. Polyphenols are bioactive molecules which play an essential role in plants response to ultraviolet irradiation, and high temperature. Flavonoids comprise the most studied group of polyphenols. This group has a common basic structure consisting of two aromatic rings bound together by three carbon atoms that form an oxygenated heterocycle. In order to support growth and increase it’s productivity, cultivation of Kale supposed to be done in good planting media. The addition of organic subtances like humic acid in planting media has proven to increase plant growth and increase productivity in several plants. The objectives of this research were to know the influence of the influence of humic acid on the growth of plant varieties and polyphenol content and to determine the best concentration of humic acid in increasing growth and polyphenol content. The current research method was carried out experimentally a completely randomize design in a split plot method. The main plot was plant’s varieties in 2 levels: V1: Kale Nero toscana (Brassica oleracea var. palmifolia), V2: Siberian dwarf Kale (Brassica oleracea Var. Sabellica). while the sub plot was the HA concentrations in 4 levels i.e 0 g.kg-1, 4 g.kg-1, 8 g.kg-1, and 12 g.kg-1 of planting medium, The parameters used in this study are fresh and dry weight. These data were obtained by weighing the roots and shoots; root’s length, chlorophyll content, and polyphenol content in kale. The data of polyphenol content was obtained by extracting the plant material following a maceration method then calculated using the Folin ciochalteau spectrophotometric. The data of plant’s growth and polyphenol content obtained was analyzed using (F test) with standard deviation rate of 5% and 1%. The results of the analysis of variance which has a significant different, followed by the least significant difference test (LSD). And for the result is the treatment of humic acid increase the growth and polyphenol content of Kale Nero (B. oleracea var. Palmifolia) and Siberian dwarf kale (B. oleracea Var. Sabellica).

BSF able to convert organic waste into nutrients for growth and development. The purpose of this study was to determine the effectiveness of the frequency of feeding carica industrial waste on the development of BSF larvae, to determine the effect of feeding frequency on the increase in larval biomass and to determine the survival rate of BSF larvae. The study used an experimental method with RAL factorial. The first factor is type of feed, carica and chicken pellets. Frequency of feeding as the second factor is the frequency of once a day, every two days and three days. Variable of the experiment is head capsule, number of prepupae larvae, larval biomass and survival rate. The data obtained were analyzed by ANOVA at an accuracy level of 95%, if it had a significant effect, it would be continued with the DMRT test. The results of the study The frequency of feeding both once a day (F1), twice a day (F2), and every three days (F3) had no effect on the development of BSF larvae (P> 0.05). The frequency of feeding affects biomass of larvae, the frequency of feeding every day (F1) has the highest biomass while the mechanism of feeding frequency every three days (F3), although given the same quantity of feed weight per day has the lowest biomass. The survival rate of carica feeding is lower, which is about 60-70% at the three different frequencies with chicken pellet feeding which still reaches 90% in each treatment.

Abstract

Alien fish are introduced to diversify farmed fish, ornamental fish, or disease vector controllers. Alien fish in aquatic generally becomes a threat for indegenous fish as competitors for food, space and as predators. This will affect fish structure populations and results in niche segregation (space utilization) to avoid competition. Niche segregation encourages certain fish to occupy niches spatial and temporal diferently. Niche segregation may also occur between O. mossambicus and O. niloticus in the Banjaran River. This research was done by using a survey method with the Purposive Random Sampling technique. Sampling was conducted at five selected stations along Banjaran River every two weeks from July until September 2018. Research variables were O. mossambicus and O. niloticus populations with parameters abundance, length and weight of fish The supporting variable was water quality with the physical parameters were temperature, brightness, and current and the chemical parameter were dissolved oxygen (DO) content, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and also potential hydrogen (pH). Data on fish population structure and niche segregation were analyzed descriptively. Correlation between physical-chemical aquatic factors and fish abundances were analyzed using PCA (Principal Component Analysis). The result showed that the O. mossambicus population was more than O. niloticus. The abundance of O. mossambicus in the five stations were different (p: 0.005), while the abundance of O. niloticus were relatively the similar (p: 0.184). There were differences in length distribution of O. mossambicus (p: 6.934E-09) and O. niloticus (6.174E-05) at five stations. The weight distribution of O. mossambicus at five stations was significantly different (p: 3.609E-09), and the weight distribution of O. niloticus (p: 6.631E-05) was also different. The temporal niche segregation between O. mossambicus and O. niloticus was recorded in stasiun 5. The abundances of O. mossambicus and O. niloticus were negatively correlated to the physical and chemical factors of the water quality of Banjaran River
