Abstract

This paper explains the change of Dayak Bukit's dwelling in the Meratus Mountain in South Kalimantan Province, Indonesia. This research utilized naturalistic paradigm based on the axioms of the nature of reality. By focusing the study on local people, this research employed ethnography met, .od, particularly domain analysis. Interpretation of the domain came into the result that balai-adat is one of the shelters of Dayak Bukit tribes. Currently, Dayak Bukit tribes do not live in a communal dwelling anymore, but live in scuttered housing. Consequently, the function of balai-adat shift from a dwelling into a place of ceremony and cultural activities. It is concluded that balai-adat is an identity of the groups and it corltributes to maintain the existence and the representation of the structure of the Bukit Dayak tribes.Keywords: dwelling change, balai-adat, Dayak Bukit tribes, identity of the groups.

Abstract

Visual comfort Prameter is the level suficient of illumination recommended which is not exceed the threshold contrsat and stated brightness level, and no room glare occured. Not only to illuminate the work space, level of illumination also effects on the room condition (comfort and fun) that create a comfortable oflce work space.The goal of this research is to recognize the influence of furniture lay out and light spot placement on the work space, and if the color of materials effect on the reflectance value of wall and ceiling. In this study, descriptive metode applicated on the Dialux program concluded that light point and furniture lay out made effect on the illumination level of the work space, and the color of materials influence the effect of reflectance.This research is expected to serve as guidelines in designing office work space inaccordance with the recommended illumination level.Keywords: illumination, luminance, visual comfort

Abstract

This research is aimed to getji-equency spectrum of EEG signals for the motor movement and imagination of motor movement. EEG data is measured from scalp electrode of C3, C4, P3 and P4 (Central and Parietal). The motor movement in this research is "turn right” and "turn left” in which the steering wheels are used to facilitate the volunteer in having concentration. Imagination of motor movement meanwhile represents desire of volunteer to turn steering wheel either to right or to left. Fourier transform is used to transform signals in time domain becoming signals in frequency domain. The result in this research shows the difference of frequency spectrum among motor movement of "turn right" and "turn left" as well as in imagination of motor movement. Keywords: BCI, ERS/ERD, transformasi fourier, motor movement

Abstract

Adopting e-Learning in high school is challenging. The main problem in this situation is the adoption of e-Learning as a self-paced learning. In universities, the problem rarely happens since the students in universities have an awareness to explore and to learn by themselves. In high school level, student awareness is limited.High school students more likely need a control mechanism to use e-Learning. In this research, an efort is made to create a model that collaborate parents to control e-Learning usages. The collaboration of parents in e-Learning strongly believed can provides additional value of effectiveness in student e-Learning usage.The result of this research is a model called PCM (Parental Control Model). PCM is an architectural model that contains of information and software architecture that will cover business process collaboration between parent and student.Keywords: e-Learning, parental control model, software architecture, interaction model

Abstract

Theoretically environmental isotopic compositions ofprecipitation decrease with increasing altitude. Linear regression analysis was applied to environmental isotopic compositions (δ18O, δ2H) data on 15 precipitation samples collected along an altitudinal 126 to 1260 m.asl from November 2011 to February 2012 to determine the local meteoric water line for southern slope of mount Merapi. Merapi meteoric water line (MMWL) is an equation that describes the relationship between isotopic compositions of precipitation with altitude. This study was completed as part of a larger research of the groundwater dynamics studies using natural isotopes for southern slope of mount Merapi.Isotopic compositions of precipitation samples were measured using Liquid-Water Stable Isotope Analyzer LGR DLT-100 at the Center for the Application of Isotopes & Radiation Technology Laboratory, National Nuclear Energy Agency (BATAN), Jakarta. Regression results for the precipitation samples for southern slope of mount Merapi yielded a MMWL defined by the equation δ2H=8.332 δ18O+15.068(r2 =0,998); the change of isotopic compositions in precipitation with altitude of about -1.2%d100m for deuterium and -0. 1 %dl 00m for oxygen-18.This equation will be useful as reference for hydrological dynamics studies on the southern slope of mount Merapi that use isotopes of 2H and 18O to trace sources of ground-water recharge, to evaluate mixing of sea-water and groundwater, to analyze groundwater-mineral exchange, and to analyze many other groundwater contamination problems.Keywords: precipitation, isotope ratio, isotopic composition, m.asl, MML .

Abstract

Face recognition systems have been widely used in various security applications, for example in attendance system. The success of face recognition system relies on the trained face images as well as the face image captured that being recognized. Among the variables that determine the success of face recognition is face pose. Previous works showed that frontal face pose produced the best face recognition success rate. This paper proposes a face pose tracking sub system that can be used as a filter so that only the frontal face pose that will be processed in the face recognition sub system. The criteria for various face poses, i.e. frontal, tilted and turned, either left or right, have been formulated. Experimental results showed that the success rate of face pose recognition were between 64% up to 96%, with average of 84,7%.
