Polyploidy is a common phenomenon in plants, especially on the species of ferns. The objectives of thisresearch are to find out the variation of the ploidy levels, to know the effects on the stomata index and size ofstomata and spore in Adiantum raddianum. The materials used to conduct this observation of chromosomes numberwere made from root tips or young leaf tips (croziers). The modified squash method was used in microscopicpreparation. The result of the observation showed that there was a variation in ploidy levels from 2n = 2x (diploid) to2n = 7x (septaploid). It appeared to be general trend that the higher level the ploidy causes the lower the indexstomata but the bigger the stomata and the spore size.

Yoghurt is a fermented milk product that can provide beneficial effects to the health of consumers. Increasing the quality of yoghurt can be made by combining the benefits of probiotic with prebiotic to produce sinbiotic yoghurt. Inulin is a prebiotic that found in many dahlia tuber (Dahlia variabilis Willd.). Pure inulin were expensive, so the alternative is using dahlia tuber flours filtrate as prebiotic ingredients. This study aimed to examine the addition of Dahlia Tuber Flours Filtrate (DTFF) as a prebiotic in sinbiotic yoghurt making using Lactic Acid Bacteria (LAB) Lactobacillus bulgaricus, Streptococcus termophilus dan Lactobacillus acidopilus as probiotic. This research using Completely Randomized Design (CRD) with 4 concentration treatments DTFF 0%, 3%, 6% and 9% with 3 replications. Observed variables consist of the number of total LAB, lactic acid level, pH and organoleptic attributes (aroma, flavor, consistency and impression). Data the number of total LAB, lactic acid level and pH values â€‹â€‹were analyzed by ANOVA, continued by Duncan test, while the organoleptic data was analyzed by Mann-Whitney U test with 95% significant level. The results showed that the addition of DTFF significantly affect the increasing of total LAB, lactic acid level, organoleptic assessment and decreasing pH of sinbiotic yoghurt. Sinbiotic yoghurt with 3% of DTFF concentration is most preferred by panelists and required the criteria of Indonesian National Standard (SNI) for yoghurt with enough likely aroma, sour taste/specify and enough thick texture with total LAB 2,4 x 108 CFU/ml, 1.3% lactic acid levels and 4.2. pH.

Quail child has a tremendous potential to continue further descent because quails have almost all the potential that can be exploited by humans, either for consumption or economic. Children quail superior quality can be produced from superior quality parent, so the parent quail quality must be considered. Additional food in the form of powder turmeric supplements can increase the phytoestrogen which stimulates the liver to produce vitellogenin as theÂ material forming the yolk. Egg yolk is a source of nutrients for the development of quail embryos. This study aimed to analyze the differences in the quality of the parent male quail chicks were given supplements of turmeric powder to the testis weight, testis size, number of spermatogonia and spermatids amount contained in the seminiferous tubules. The study design used was completely randomized design (CRD) that is 3 treatments and 5 replications. By using quail male child as much as 15 tails as test animals, divided into three groups, namely K0: F1 generation of the female quail are not given turmeric powder supplement, K1: F1 generation of the female quail turmeric powder supplemented with a dose of 54 mg/tail/day and K2: kuturunan F1 of the parent quail turmeric powder supplemented with a dose of 108 mg/tail/day. The variables measured were testis weight, testis size, number of spermatogonia and spermatids number. Data were analyzed using Analysis of Variance (ANOVA) followed by a further test Duncan Multiple Range Test (DMRT) at the 95% significance level. The results showed that the quality of parent child quail turmeric powder supplemented with a dose of 108 mg/tail/day for better views of the process of spermatogenesis.Â Keywords: Child Â quail Â (Coturnix Â coturnix Â japonica.

Oleoresin cinnamon bark belonging to the phenolic compounds that are known to have potential as antioxidants. On the basis of the potential of these compounds may be used to prevent or repair tissue damage, whether caused by the factors of age and condition of oxidative stress hypercholesterolemia. This study aimed to obtain skin and bone collagen profile of Wistar rats at various ages after oxidative stress treated hypercholesterolemia and oleoresin from the bark of cinnamon (Cinnamomum sp). This study used 54 male Wistar rats with body weight (200 Â± 5 g), which are grouped into six treatment groups combined with the three age groups of mice that is three, six or nine months with three replications. Each group received treatment oleoresin and hypercholesterolemia. Giving oral oleoresin conducted on rats given oral way during the 7 days with a dose of 12 rats mg/200-gr bw / day. Hypercholesterolemic rats was conducted by feeding cholesterol content within 1% during the two months. The results showed that the profile of skin and bone collagen content of the highest found on threemonth old rats treated with oleoresin, oleoresin hypercholesterolemia and given again (P6, 2), namely 57.44 tg / mg and 33.47 tg / mg, while the profile of skin and bone collagen content of the lowest found in rats aged 9 months to get treatment without treatment of hypercholesterolemia oleoresin (P2, 9), namely 28.26 tg / mg and 10.65 tg / mg. From this research can be concluded that the condition of hypercholesterolemia and duration of the aging effect on skin collagen levels decrease and bone, and vice versa oleoresin at the age of young rats that received the treatment of oxidative stress could repair or prevent hypercholesterolemia decreased content of skin collagen and bone. In general, the rats are treated oleoresin and young age profile of the collagen content of skin and bones better compared with rats that do not get treatment in conditions of oxidative stress oleoresin hypercholesterolemia.
