Abstract

Highly seismic activities in Indonesia, that is followed by a lot of high magnitude earthquakes, make awareness of the people to anticipate the damage that caused by this disaster. The Codes of earthquake have changed and are accompanied by the change of seismic region. There must be some efforts to improve the existing building structure. One of the efforts is retrofitting the beam-column joint which is the weakest element of structure in the building when subjected to earthquake loading. Four beam-column joint reinforced concrete specimens, namely SJC, SJ-01, SJ-02, and SJ-03, made of normal concrete and plain reinforcement were tested in this experimental program. Beam with 150 mm width, 250 mm high, and 1500 length be jointed with column that has section area of 250 mm x 250 mm, and 1750 mm length. The specimens of SJ-01, SJ-02 and SJ-03 were retrofitted by triangular voute in lower side of the beam in the beam column joint region with 125 mm, 187.5 mm, and 250 mm side length, respectively. All specimens are tested with cyclic loading using hydraulic actuator. The results show that the increasing strength of specimen SJ-01 and SJ-03 compare to the reference specimen were 12.74% and 10.29%, respectively. While the strength of specimen SJ-02 a little bit decreasescompare to the reference specimen.Keywords: beam-column joint, reinforced concrete, retrofitting, voute, cyclic loading.

Abstract

The research tries to explain the specific Hulu-Teben concept of Bayung Gede custom village as dialog result between the normative Hulu-Concept as a background knowledge with the phenomena of spatials system anomaly at Bayung Gede customvillage.The research utilized phenomenology paradigm of Hussrel where Hulu-Teben of custom village in general takes a role as background knowledge. It’s discussed with the macro spatial system of Bayung Gede custom village to show the uniqueness spatial as the architectural anomaly of mountain village. Deepening study of the anomaly above was done in gaining the community’s social-culture background/their local wisdom as thetranscendental consciousness. Further Hussrel emphasizes that the highest transcendental peak is obtained by doing the three steps of reduction, i.e : (i) a phenomenological reduction of all related information to get some empirical themes, such as ; (a) Upperengga Mala and (b) Tegak Paumahan, (ii) the eidetic reduction of the three empirical themes to generate the architecture concept and (iii) the final reduction is transcendental reduction to discovery the architecture local theory. In the context within the research of Bayung Gede custom village, the aim is only focused at the architecture concept.The research results show that Hulu-Teben concept of Bayung Gede custom village has adapted Hulu-Teben in general shown by existence of Para Kahyangan Desa (custom village religious indicator) as the appreciating expression form for community’s ancestor. On the other hand, there are some spatial anomalies as an additional and enriching the general Hulu-Teben concept. Those are related with their local wisdom, it’s not only for appreciating their ancestors (upper level of human being) but it’s also for : (i) the former king of Jaya Pangus and the queen of Ulun Danu Batur (upper level of human being but they’re not ancestors), (ii) the equal level of human being and (iii) lower level of human being (the plantation, the animal and other creature).Keyword : Hulu-Teben spatial “anomalies” Bayung Gede, Custom Village

Abstract

One of the problem faced by Indonesian batik industry is about environment issue. This is because batik industry uses synthetic dyes on their coloring process. The use of natural dyes for batik makers deemed to be impractical and has many disadvantages, including lack of bright colors, longer process, and more expensive. Therefore, this research aims to reduce the use of synthetic dye in batik design process, by developing computer aided batik color design (CAD for batik color). This development includes a method for predicting color, methods and algorithms used in the CAD and measurement of its usability level. The results showed that the method can predict color with average error rate of 5% (< 10% tolerance error established), CAD for batik color has been able to run as the concept of batik making, and its usability average value is 3.86. Therefore, it is concluded that CAD for batik color has usability aspects and can be implemented as a design batik color tool that can be operated by its user.Keywords: batik, creative, design, CAD, color

Abstract

This research was done to determine the distribution channel strategy based on characteristics of successful products. Totaling 100 products from 15 types of product categories were used as a research object. Independent variables consisted of product characteristic variables and distribution channel variable. Product characteristic variables consisted of price, safety, feature, product performance, service, convenience, brand, and design. Coverage was used as adistribution channel variable and market share as a dependent variable. Ordinary Kano and Modified Kano were used to construct some mathematical models. Each model then was evaluated with coefficient determination test. The mathematical model constructed in this study has R2 value 16,26%. Coverage included in one-dimensional requirement which means adding value to coverage variable will linearly increase market share.  Keyword: channel distribution strategy, product characteristics, Kano model, mathematical model.

Abstract

The Government has made traffic laws and regulations to create a motor vehicle safety and in order to reduce the number of fatal and serious injuries that occur in motor vehicle crashes every year. However, it’s not much effecting to diminish numbers of road accident causing by lack of knowledge, insights, driving experience, and often to take a risk. This study aimed to identify the effective education in safety driving to improve the driver’s performance which has a risk taker characteristic. This study was conducted in a laboratory simulation of ergonomics with the respondent amounted 30 people aged 18-25 years and classified into three groups: 10 respondents are educated by using a module, 10 respondents are educated by watching a video, and 10 respondents directly practice using a simulator. Holt & Laury’s Questionnaire is used to knowing Risk Attitude of respondents. This study showed that video education is the most effective education to reduce a numbers of driving perform interference for those man and woman’s respondents and afterwards followed by module’s education and the last intended by without educationKeywords: risk taker, impaired driving performance, performance time on a task
