Abstract

This research aimed to study Piridoksin (Vitamin B6) status in blood sample of Attention Deficit Hyperactivity Disorder (ADHD) children. Deductive research using the descriptive method through 2 stage, namely : (1) Taken of blood sample, and (2) Analysis of Piridoksin (Vitamin B6) status in blood sample was performed by using High Performance Liquid Chromatograpy (HPLC) method. Data collected and assessed by once in one time. Data were analyzed using descriptive analysis techniques and Chi Square tests (X2) by Computer programs (SPSS 15). The result of the assessment of Piridoksin (Vitamin B6) status in blood sample of ADHD children that had been was considered statistically highly significant a reduce of the assessment of Piridoksin (Vitamin B6) status in blood sample of ADHD children by 0,422 ng/ml compared with laboratory reference (control) by 0,36-1,8 ng/ml, HA<C** (p<0,001). This was considered a reduction in Piridoksin (Vitamin B6)) concentrations induces of the Hyperactivity children by 95%.

Abstract

Lemon Citrus (Citrus limon (L.) Burm f.) is one of the plants that has potential as a traditional medicine, and is an excellent source of vitamin C and calcium. Lemon leaf lemon can help overcome cancer, heart and liver. The purpose of this research is to characterize simplicia leaf and to know the chemical compound group contained in leaf. Characterization of simplicia include macroscopic and microscopic examination, determinations of loss on drying, determinations of water soluble extract, determination of ethanol soluble concentration, determination of total ash content, and determination of acid ash in soluble. Phytochemical screening includes the test for alkaloids, flavonoids, steroids/triterpenoids, tannins and saponins. The result obtained from examination of lemon citrus leaf characteristic gave loss on drying 69,29%; total ash content 6,40%; acid insoluble ash 1,23%; ethanol soluble extract 17,73%; water soluble extract 24,79%. The result of phytochemical screening showed that lemon leaf simplicia extract contains alkaloids, flavonoids, steroids/triterpenoids and tannins.

Abstract

Zingiberaceae is one of perennial herbaceous plant that was unique to its rhizomes. This is because the Zingiberaceae contains evaporated oil or had an aromatic odor. This research was conducted in February to March 2018 in the Telagah Forest of Gunung Leuser National Park, Langkat Regency. This research used descriptive procedures with observation techniques. The result based on observations obtained 11 species of Zingiberaceae, with 7 Genus of Zingiberaceae. The Globba Genus has the most number of species, 4 species (Globba nawawii Ibrahim & K. Larsen; Globba paniculata Valeton; Globba patens Miq; and Globba pendula Roxb.), Etlingera Genus (Etlingera alatior (Jack) R.M. Sm.; and Etlingera littoralis (J. Konig) Giseke), Amomum Genus (Amomum ochreum Ridl.), Curcuma Genus (Curcuma sp.), Hedychium Genus (Hedychium coronarium Koenig.), Hornstedtia Genus (Hornstedtia tomentosa (Blume) bakh.f.) and Zingiber Genus (Zingiber multibracteata Holtt).Keywords: Zingiberaceae. Rhizomes, Gunung Leuser National  Park.

Abstract

Pirdot is a natural medicinal plant contains flavonoids that has antibacterial properties. The bacteria tested in this experiment is E. coli that causes of diarrhea. This study was to determine the antibacterial effect of pirdot leaves made in an extract preparation by the diffusion method using paper discs.. This study also used Tetracycline as a comparison, where this antibiotic is very sensitive to E. coli bacteria. Pirdot leaf extract was made in various concentrations, namely 12.5%, 15%, 17.5% and 20% and 20 mcg and 30 mcg of Tetracycline concentrations. The results showed that pirdot leaf extract in E. coli was able to inhibit with a concentration of 12.5% of 10.41 mm, 15% of 11.71 mm, 17.5% of 14.08%, and 20% of 15.43 mm, while the 20 mcg Tetracycline comparison was 18.73 mm and 20.71 mm at 30 mcg. So the conclussion from this research are the concentration of 12.5% and 15% can not be not said to be antibacterial but at concentrations of 17.5% and 20% can be said to be antibacterial. Keywords: Pirdot leaf, Eschericia coli, antibacterial.

Abstract

This study aims to determine levels of nutrients N, P, K, C- organic and ratio of C/N on papaya fruit liquid organic fertilizer, knowing the effect of giving papaya fruit liquid organic fertilizer on growth and yield tomato plants (Solanum lycopersicum L) and find out the optimal concentration of liquid organic fertilizer of papaya waste on the growth anad yield of tomato plants (Solanum lycopersicum L). This research was conducted at the green house, Faculty of Science and Technology, North Sumatra State Islamic University in November to February 2020. The paraneters used are stem height, Number of leaves, Number of branches, number of flowers, and number of fruits. This study used a completely randomized design with four treatment and five replication as the trearment used is treatment 0 (0 %) , treatment 1 (10 %), treatment 2 (20 %), treatment 3 (30 %). The highest research results were found in treatment 3 concentrations of 300 %, while treatmen 2 concentrations of 200 % and treatment 1 concentrations of 100 % good growth, while the lowest growth was found in control. Keywords: Tomatoes, Liquid Organik Fertilizer, Papaya Waste.
