Abstract

Down syndrome is characterized by maxillary hypoplasia with a short and narrow palate, resulting in a smaller shape and volume of the oral cavity. Research findings by experts on the cavum oris volume of individuals with Down syndrome indicate differences due to genetic abnormalities, secondary causes,and age. This purpose of this study is to analyze the relationship between age and  cavum oris volume in children with Down Syndrome at the Special School in Yogyakarta City. An observational study with a cross-sectional approach was conducted on 28 children with Down syndrome at the Yogyakarta Special School who met the inclusion and exclusion criteria. The digital printing of the cavum oris is performed using Shining 3D Dental. Measurement of cavum oris volume using 3Shape 3DViewer and Inventor Professional 2020. The relationship between age and cavum oris volume was analyzed using statistical tests of correlation coefficients and T-tests with a 95% confidence level. The results show an R value of 0.942, which means there is a very strong positive correlation between increasing age and increasing cavum oris volume. The T-test shows that the age variable has a t-value of 3.967 with p=0.058 (p<0.05), indicating that the age variable does not have a significant effect on the volume of the cavum oris. The research conclusion is that in children with Down syndrome, the volume of the cavum oris increases with age, but this increase is not significant.

Abstract

Soybean yields in Rokan Hulu continue to increase along with the increasing population and the increasing diversity of basic soybean growth, the increasing demand for soybeans is not accompanied by growth by Rokan Hulu farmers, this is due to the decreasing area of ​​land that can be planted with soybeans and low soil fertility, so efforts need to be made towards the growth and yield of soybeans, it is hoped that the use of organic mulch of alang-alang can increase soybean yields. This study was conducted to determine the effect of giving several doses of organic mulch of alang-alang on the growth and yield of soybeans. This study used a Randomized Block Design (RAK) with 5 treatments, each treatment had 4 groups of plants, where each plot consisted of 10 plants. The treatments are P0 = without organic mulch of cogongrass, P1 = organic mulch of cogongrass 5.6 kg, P2 = organic mulch of cogongrass 7.2 kg, P3 = organic mulch of cogongrass 8.8 kg, P4 = organic mulch of cogongrass 10.4 kg. The variables observed were plant height, leaf width, number of plants, flowering age, harvest age, number of filled pods, wet seed weight, dry seed weight, weight of 100 seeds. The results of this study were seen from the results of the Duncan multiple distance test (DMRT a 5%). The provision of organic mulch of cogongrass on soybean plants had a significant effect on harvest age, flowering age, number of filled pods, wet seed weight, dry seed weight, weight of 100 seeds and had no significant effect on plant height, leaf width, number of leaves. This is due to the suboptimal nutrients given to the soil. The provision of organic mulch of alang-alang grass with a dose of 8.8 kg tends to affect the growth and yield of soybean plants.
