The policy about teacher professionalism has been applied for last decade in Indonesia. However, science and technology development, changes in society, innovation in teaching and learning theory, and all other changes demand a sustainable teacher empowerment system. Considering this demand, it is necessary for UniversitasNegeri Medan, as an educational institution and also teacher training university, to develop a policy that support the empowerment system of professional teacher. In previous funding term such a system had been developed and one of components of this system is informational system. This article describes an aspect of this informational system development process, which is the development method used to build the informational system. There are many informational system developmental methods available. The question is which one is more suitable for the purpose of empowering teacher sustainably. Considering that the function of the informational system is to connect UniversitasNegeri Medan with the stakeholders including teachers, than the system needs to put importance to the human aspect. Hence the model described in this article is called ETHICS (Effective Technical and Human Implementation of Computer Based Systems). One thatbalances the human and technical aspects in developing the informational system..

PDAM Tirtanadi Medan is a water utility company. According to [1] PDAM Tirtanadi hasn’t built new installation for 10 years. It is predicted that distribution network still forming a circuit so that hasn’t been optimized [2]. The network will be optimal if a pipe installed isn’t forming a circuit without reducing the function of the pipe water. Modification network deleted circuit can be done by looking for minimum spanning tree. Many literatures contain several algorithms to solve minimum spanning tree problem like travelling salesman problem [3,4], Prim’s algorithm [5-7] and Kruskal’s algorithm [8]. In this work, the examination of a circuit done with a minimum spanning tree using TORA software.

High intensity physical activity requires large amounts of antioxidants. Exhausting physical activity can decrease glutathione peroxides levels in response to increasing production of free radicals. Glutathione peroxides levels to eliminated free radicals and reduce oxidative damage. This study aims to know effect antioxidant redfleshed pitaya extract to increase glutathione peroxides. The subject of this research are 16 male rats, age 3 months with average weight of 200 gr, divided into 2 groups. Group 1 (OS-RFP) : the induced oxidative stress and given aquadest, group 2 (OS+RFP) : the induced oxidative stress and given 100 mg/kgWB of red-fleshed pitaya extract. Oxidative stress is given was swam for 20 minutes, thrice a week for 3 weeks. The glutathione peroxides levels in the group1higher than the group 2. There were significant differences in the increasing glutathione peroxides levels (p=0.000) between group 2 and group 1. This research shows that glutathione peroxides levels have increased in oxidative stress groups given red-fleshed pitaya extract. Red-fleshed pitaya extract has to increase glutathione peroxides levels that is can eliminate oxidative stress.

Dendrocygna javanica (Horsfield, 1821) is a member of the family Anatidae, the order of Anseriformes, class of Aves, phylum Chordata, of kingdom Animalia. This species is commonly called the Lesser Whistling-duck because it flies in a noisy sound. In Indonesia, it is known as Belibis Batu. Dendrocygna javanica is spread in the regions of Asia including Indonesia. In Indonesia, D. javanica is spread on the islands of Sumatra, Kalimantan, Java, East Nusa Tenggara and West Nusa Tenggara. This study aims to create a distribution model of Dendrocygna javanica based on habitat characteristics in North Sumatra, Indonesia, using GIS (Geographic Information System). A total of 35 distribution points of D. javanica in 8 districts in North Sumatra were analyzed using ArcGis 10.3 software to analyze habitat characteristics. The results showed that D. javanica spread on habitat characteristics Rainfall ranged from 1500-3500 mm/year, 5 soil types namely ferric acrisols (4 points), humic acrisols (4 points), dystric cambisols (2 points), orthic ferrasols (5 point), and dystric fluvisols (20 points), 7 types of land cover namely dryland forest (2 points), plantation (5 points), dryland agriculture (10 points), rice fields (2 points), swamp (4 points), plus (4 points), and body of water (8 points), and are at an elevation of 3-1072 meters above sea level. Dendrocygna javanica is spread in a limited area. This research is expected to be an important source of information in the conservation of D. javanica in North Sumatra
