Abstract

This research was conducted to determine the species diversity of macrozoobenthos and determine the condition of physical and chemical factors in the waters of estuary river in  Nipah Village Perbaungan District Serdang Bedagai Sumatera Utara. The result of diversity of macrozoobenthos obtained 28 species with one phylum, 2 class, 7 orders, 18 families and 20 genera. Measurement of physical and chemical factors waters obtained an average pH 7 both ebb and tide conditions; in conditions of salinity waters receded an average of 0 and at high tide the average of 5; the ebb and tide conditions an average temperature of 27-30°C; Average current speed 10,5-19,1 cm/s; Brightness average water 14-16,3cm; and an average depth of 40,3-150cm. Values obtained by the abundance of species which are 3378-5322 ind/m2. Macrozoobenthos types that dominate the river mouth Nipah are gastropods. Values Diversity Index (H ) macrozoobenthos of 2.152 to 2.762 were classified into well water. Uniformity index (E) showed a value of 0.397 to 0.532 (deployment is not uniform or uneven). Value Dominance Index (C) showed a value of 0.074 to 0.170 (the dominance of low or no kind dominance). In general, relatively good water conditions and suitable for life macrozoobenthos.

Abstract

The 21st century learning science paradigm is not simply recite facts and understanding the concept but should be able to explain how to build skills to solve problems together. The purpose of this research is to describe; (1)  the granting of aid (schaffolding) by teachers and students to other students who are still in need of assistance in the teaching and learning process, and (2) to describe student behavior after learning over at the SDIT Lukmanul Hakim Langsa about environmentally conscious efforts. The research is used descriptive qualitative methode. Data collecting tool used is a form of observation. The results showed that the importance of environmentally conscious inculcation efforts early on to be done simultaneously and consistently by all stakeholders of the school. The easiest thing is to provide live examples to the students so that they are interested in learning science.

Abstract

Asiatic citrus psyllid Diaphorina citri Kuwayama has been considered as one of important citrus pests and a vector of a serious citrus disease as well, greening disease or known as Huanglongbing (HLB). Among entomophatogenic fungi which can be used to control those pest insects isBeauveria bassiana.The objective of this study was to measure the infectivity ofB. bassianaagainst adult of D. citri.B. bassianaconidia that used were 103, 104, 105, 106, 107, and 108conidia/ml.The experiment was repeated three times and arranged in a completely randomized design (CRD). Mean was analized by Duncans multiple range test correction at the level α=0.05. B. bassianacaused mortality of D. citriat rate of 10%, 15%, 18.33%, 26.67%, 33.33% and 53.33% respectively. The result showed that LC50 of B. bassianawas 1.52 x 108conidia/ml.

Abstract

Underwater plants are plants in the form of herbaceous plants and shrubs and low plants that cover the bottom of a forest area. Thus the function of the plant here is to withstand the destructive power of the falling rain fall and the rapid flow of water above the soil surface. Sibolangit Nature Park is a forest area with an area of ± 24.85 Ha. The existence of the lower plants in Sibolangit Nature Park become the main attraction for the visitors. The purpose of the research is to obtain the inventory data of the lower plants and describe the characters morphology. The research was conducted by using the exploration method along the path of Sibolangit Nature Park. From the research that has been done, there are 48 types of plants that consist of 31 families. Of the 48 undersea species identified, 30 of them belong to the Spermatophyta division, while the remaining 18 are included in the Pterydophyta division.Underwater plants are plants in the form of herbaceous plants and shrubs and low plants that cover the bottom of a forest area.

Abstract

This research aims to study Tartrazine and Zinc (Zn) status in blood sample of Attention Deficit Hyperactivity Disorder (ADHD) children. Deductive research using the descriptive method through 3 stage, namely : 1. Taken of blood sample, 2. Analysis of Tartrazine status in blood sample was performed by using High Performance Liquid Chromatograpy (HPLC) method, and 3. Analysis of Zinc (Zn) status in blood sample were measurements by using Atomic Adsorbance Spectrophotometry (AAS) method. Data were analyzed using descriptive analysis techniques and Chi Square tests (X2) by Computer programs (SPSS 15). The result of the assessment of Tartrazine status in blood sample of ADHD children that had been was considered statistically highly significant a increase of the assessment of Tartrazine status in blood sample of ADHD children by 130 mg/ml compared with laboratory reference (control) by 28 mg/ml, HA>C** (p<0,001). The result of the assessment of Zinc (Zn) status in blood sample of ADHD children that had been was showed statistically highly significant a reduce of the assessment of Zinc (Zn) status in blood sample of ADHD children by 0,37 µg/ml compared with laboratory reference (control) by 0,64-1,18 µg/ml, HA<C** (p<0,001). This was considered a reduction and increase in Tartrazine and Zinc (Zn) concentrations induces of the Hyperactivity children by 95%.

Abstract

Leaves of sangitan (Sambucus javanica Reinw) are often found but noticed. The leaf part of the sangitan plant is used to treat swelling, insecticides, antidiarrheal, antiinfectives, wounds, smoothing the skin as it contains flavonoid chemical compounds, glycosides, anthracton glycosides, saponins, steroids / triterpenoids and tannins. Screening results of ethanol extract of sour leaves (SambucusjavanicaReinw) contain alkaloid compounds, flavonoids, glikosida, antrakinon glycosides, saponins, steroids / triterpenoids and tannins. The extraction of sangitan leaves was done by maceration using 96% ethanol. Examination of antibacterial activity of ethanol extract of sangitan leaves was done in vitro by diffusion method of wells with concentrations of 500, 400, 300, 200 and 100 mg / ml. This study used cotrimosazole as a comparator and 96% ethanol as a negative control. The extract of ethanol leaves sangitan showed anti bacterial activity against bacteria Eschericia coli and Salmonella thypi at concentration 500 mg / ml respectively 16,11 mm and 17,04 mm which is classified strong but when compared with antibiotic cotrimosazole 10 mg / ml visible diameter of inhibit ethanol extract Leaves sangitan still much lower that is 30,35 mm in bacterium Eschericia coli and 33,15 mm in Salmonella thypi bacteria whereas ethanol extract do not show inhibitory power.
