Bacterial isolation was conducted on chitin medium incubated at 31 ÌŠC. Chitinolytic index was measured as ratio of clear zone diameter divided by colony diameter. Crude enzyme activity of the isolates was spectrophotometrically assayed using Schales reagent at 420 nm.Bacterial identification was conducted by using its 16S rRNA gene sequences. Twelvebacterial isolateswere isolated from digestive tract oftokay gekko and eight were isolated from digestive tractof golden skink.LK12 and KD5 showed to haverelatively highchitinolytic index of 1,551 and 1,098 respectively. Optimum enzyme activity of LK12 and KD5 was observed in 6 days of incubation with activity of 0,205 U/mL and 0,225 U/mL, respectively.

Amount of children spend time at home because studying online, it means that they spend a lot of time outside with friends. This allows children to consume addictive substances. From the initial survey conducted in village of Bandar Labuhan district of Tanjung Morawa regency of Deli Serdang, it was found that children secretly consume addictive substances which are harmful to their own health, such as smoking. The method of implementing community service activities is carried out in three stages, including the stages of preparation, implementation and guidance. Addictive substances are substances that cause addiction or dependence and are harmful. From the results of the dedication, it was found that most of the abuse of addictive substances in children in village of Bandar Labuhan district of Tanjung Morawa was cigarettes, glue and gasoline.

This study aims to determine the effect of some artificial diet on the breeding of R. fuscipes assassin bug in the laboratory. This research was conducted from July to August 2018, at the Laboratory of Plant Diseases, Faculty of Agriculture, Universitas Sumatera Utara. The research method used a Non-Factorial Completely Randomized Design (CRD) consisting of controls (T. molitor), egg yolks, Artemia salina, plant foods from soybean (Glycine max). The results showed that control treatment F = 85,397 (p <0.05), egg yolk F = 17,552 (p <0.05), Artemia salina F = 8,936 (p <0.05), plant feed from soybean juice F = 8,377 (p <0.05) significant effect on R. fuscipes body length, on R. fuscipes body width only egg yolk treatment F = 7.161 (p <0.05) which had a significant effect on body weight and only soybean treatment F = 12.297 (p <0.05) which was significant.

Odonata are insect which function as bioindicator and conservation of an environment status in the area. The sampled were collected using a sweep net (400 μm mesh, 60 cm x 90 cm) with six times the swing starts at 0900 until 1200 noon hour and identified in the laboratory. Consist of two sub-orders, 4 families, 24 genera, 32 species and 156 individuals identified dragonfly. Orthetrum sabina, Pantala flavescens and Agriocnemis femina are the kinds of dragonflies dominant, while two types of Vestalis/Arethystira amoena and Tholymis aurora is found only in the Station 3. As much as 54% relative abundance of family Coenagrionidae dominated, followed by Libellulidae (35%), Gomphidae (8%) and the smallest recorded from family Calopterygidae (35).

This study aims to measure the content of heavy metals lead, Pb (sediment and white shrimp) and how much heavy metal of lead is accumulated by white shrimp (Penaeus merguiensis) from sediments. Lead, Pb of heavy metals in white shrimp and sediments were analyzed by using Atomic Absorption Spectrophotometer (AAS). The results showed that the average concentration of Pb heavy metals in sediments was found of 5,90-6,78 mg / kg, when the average concentration range of Pb heavy metals in white shrimp was found of 0,014-0,089 mg / kg, while the average accumulation of heavy metals Pb in white shrimp from sediments was found the value of 0,0075. The bioaccumulation value categorized was lower because the value was found below than 1. Penaeus merguiensis indicator of organisms can be used in measuring exposure to heavy metal Pb in water.

High-rise buildings in general minimize the use of construction materials that has a heavy weight to reduce the building load and achieving efficiency. One of construction parts that can be minimized weight is a wall construction. The materials of partition wall which produced are glass, gypsum, concrete and wood. This research uses of wood fiber materials from oil palm trunks which have reached the age of replanting. It is constituted by the growing oil palm plantations and palm oil mills in Indonesia so that it will also increase waste produced. This research uses experimental methods to determine the mixture of adhesive and oil palm trunk fiber (OPTF) in order to reach the standards of strength by find out the physical and mechanical properties of the partition. The result shows that using ratio 70:30 of adhesive and OPTF reach the standard partition wall that ...

One of the attorney's objectives must be encouraging the jury's acceptance of scientific concepts and the scientific method as applied to forensic science. Although each case is decided based upon its facts and circumstances, the laws of nature and practice of good science are still applicable to the case. Scientific evidence is derived from a process governed by the scientific method. Forensic science is the application of science to law. Law enforcement agents extensively rely upon evidence couched in what are presented as scientific principles and technology in criminal prosecutions. All cases involving criminal charges generally entail some aspect of scientific evidence and forensic science. The discipline of criminalistics utilizes familiar laboratory techniques and procedures to solve crime but does not always do so scientifically. Forensic science is applicable to civil cases in certain instances. Forensic science is the most persuasive of all evidence. Jurors must be prepared to treat it as science and be given basic scientific tools to evaluate it by the attorneys in the case.
