The growth of time demands human to evolve needs. House as a primary needs is inseparable from the development of human life needs, especially in urban areas. The phenomenon of urban houses requires architects, developers, and even residents to be able to plan and collaborate in considering needs and limitations of land use. Humid tropical climate condition is a challenge for the planners or architects in creating indoor condition of the building that is eligible for dwelling. This paper aims to describe a simulation of interior arrangement to proving a design of efficient energy houses. The houses in urban areas are density houses with diverse environmental situations including density environmental housing and real estate. The identity of urban houses is characterized by inability to organize a dense interior space. Therefore, the requirements of comfortable and healthy dwelling are not fulfilled properly. The efforts to develop efficient energy, environmentally friendly and sustainable houses can be done through optimization approach of architectural design. The purpose of optimization is to find answers for possibilities of architectural design problems in order to obtain the best solution. The method of this research has been done by field observations to determine the pattern of spatial planning in several houses in Medan. In the process of model optimization, a possible improvement of existing dwelling model is designed through cyclical and analyzing planning, and alternative solutions that are sustainable and affect each other. The results of this analysis are expected to be a benchmark for local architects, researchers, and also residents in developing design optimizations, especially houses that have been built. This paper is a further research related to model developments of houses for urban community in Medan. Through an appropriate alternative interior arrangement, this research is expected to achieve the optimum design of houses based on the character of the urban environment without losing its identity as dwelling. © 2017 The Authors.

This research focused on the effect of learning models and emotional intelligence in students' chemistry learning outcomes on reaction rate teaching topic. In order to achieve the objectives of the research, with 2x2 factorial research design was used. There were two factors tested, namely: the learning models (factor A), and emotional intelligence (factor B) factors. Then, two learning models were used; problem-based learning/PBL (A1), and project-based learning/PjBL (A2). While, the emotional intelligence was divided into higher and lower types. The number of population was six classes containing 243 grade X students of SMAN 10 Medan, Indonesia. There were 15 students of each class were chosen as the sample of the research by applying purposive sampling technique. The data were analyzed by applying two-ways analysis of variance (2X2) at the level of significant α = 0.05. Based on hypothesis testing, there was the interaction between learning models and emotional intelligence in students' chemistry learning outcomes. Then, the finding of the research showed that students' learning outcomes in reaction rate taught by using PBL with higher emotional intelligence is higher than those who were taught by using PjBL. There was no significant effect between students with lower emotional intelligence taught by using both PBL and PjBL in reaction rate topic. Based on the finding, the students with lower emotional intelligence were quite hard to get in touch with other students in group discussion. © 2017 Author(s).

Plectranthus amboinicus Lour Spreng is a medicinal plant that has many benefits, such as an antioxidant, hepatoprotective and immunostimulan. Immune status can be seen from hematological profile. This study aims to investigate hematology profile on rats induced BCG and leaf extract of Plectranthus amboinicus. 24 male rats aged 3 months and weighing between 140-200 grams divided equally into six groups, P0, P1, P2, P3, P4 and P5. P0 as controle was given aquadest. The P1, P2, P3, P4 and P5 treatment groups were given 19 g / kg AEP + BCG, 31.5 g / kg AEP + BCG, 19g / kg AEP, 31.5 g / kg AEP and BCG consecutively. The BCG were used as antigen. The AEP was administered orally for 30 days and 100 μl BCG were intramusculary administered on day 14 th and day 21. On day 31st, the rats we decapitated and their blood were collected for hematology (leucocyte (WBC), Erythrocyte (RBC), thrombocyte (PLT) count, Haemoglobin (Hb), erythrocyte sedimentation rate (ESR), MCV, MHC, and MHCH analysis. Data were analyzed with ANOVA. WBC increased significantly in treatment AEP 31.5 g / kg bw, 31.5 g AEP / kg bw + BCG and so were only given BCG. RBC tend to increase in all AEP treatment but tends to increase again when given a BCG. Hb increased in treatment P1, P2, T3 and P4, but the improvement was significant only in treatment P1. While PLT increase significantly in all treatments compared to the controls. HCT did not show significant differences but all of them were in the normal range. EAP without BCG and with the addition of BCG lowered ESR significantly, whereas BCG alone increased the ESR significantly. MCV increased significantly only in the treatment of P1 and show the same pattern with the MHC and MHCH. The conclusion that Plectranthus amboinicus Lour a positive impact on blood profiles with and without BCG. Plectranthus amboinicus Lour managed blood profile when administered together with BCG. © 2017 Author(s).

The quadratic assignment problem is a combinatorial problem of deciding the placement of facilities in specified locations in such a way as to minimize a nonconvex objective function expressed in terms of flow between facilities, and distance between location. Due to the non-convexity nature of the problem, therefore to get a 'good' starting point is necessary in order to obtain a better optimal solution. In this paper we propose a combined strategy (random point strategy to get initial starting point and then use forward exchange strategy and backward exchange strategy to get 'optimal' solution). As a computational experience we've solved the problem of Esc 16b, Esc 16c and Esc 16h from QAPLIB. Finally, we present a comparative study between Combined Strategy and Data -Guided Lexisearch Algorithm. The computational study shows the effectiveness of our proposed combined strategy. © 2017 Author(s).
