Abstract :

Background/Aims: Kaempferia rotunda (Zingiberaceae), known as kunci pepet or kunir putih in Indonesia, has been traditionally used in abdominal pain, sputum laxative, wounds and diarrhea colic disorder. This study was conducted to isolate and to investigate anti-mutagenic activity of some flavanones from K. rotunda.

Methods: The milled dried rhizoma of K. rotunda (3 kg) was extracted exhaustively with methanol. The methanol extract was partitionated three times by n-hexane, chloroform, and ethyl acetate respectively. Each fraction was fractionated by vacuum liquid chroma-tography (VLC) and purified by column chromatography gravitation. Identification struc-tures of all pure compounds were elucidated based on spectroscopic methods (UV, IR, and NMR) and compared to the spectroscopic previously reported data. Antimutagenic activity test was observed in vivo based on the number of micronucleated polychromatic cell erythrocytes (MNPCE) from male Balb-c mice (8e12 week) induced by cyclophosphamide. Results: From the dried and milled rhizoma of K. rotunda, three known flavanones, namely 5-hydroxy-7-methoxyflavanone (1), 7-hydroxy-5-methoxyflavanone (2), and 5,7-dihydrox-yflavanone (3) were isolated. The methanol extract and isolated flavanones from K. rotunda showed significant antimutagenic effect compared to control group.

DEVELOPING AN INTEGRATED MUSIC TEACHING MODEL IN INDONESIA BASED ON THE DUTCH MUSIC TEACHING MODEL
AS THE IMPLEMENTATION OF THE 2013 CURRICULUM
 
 
Abstract :

This article is based on the research done in cooperation between Yogyakarta State University
Indonesia, Hoogeschool voor de Kunsten Utrecht, and Utrecht University in the Netherlands entitled Developing The Music Thematic Teaching and Learning Based on Implementation in the Netherlands. One of the objectives of the study was to develop an integrated music teaching model as the implementation of the 2013 curriculum in Indonesia, which up to now has not been completely formulated.

The data collection techniques used were interviews, observations, documentation, and literature study. The researchers interviewed educational experts in the Netherlands, i.e. the policy makers, school principals, teachers/lecturers, students, and other stakeholders. The researchers also observed the music teaching learning processes in the Netherlands, from the early childhood education, primary school, secondary school, and the university level.

The findings showed that the integrated music teaching model developed in the Netherlands had the characteristics which were in accordance with the new curriculum of Indonesia, so that the model can be applied in Indonesia, which was in accordance with the characteristics of the teaching situations in Indonesia. The procedures are: a) the teacher gave explanation about the core materials; b) the teacher gave an assignment to be done in groups, each group having different assignments but each assignment became a part of the class project; c) the students discussed the assignment and formed the music concept and practiced the materials which would be performed; d) the students presented their works in groups; e) the students had a reflection; and f) evaluation.

The Third Information Systems International Conference
Impact of Government Support and Competitor Pressure on
the Readiness of SMEs in Indonesia in Adopting the
Information Technology

Abstract :

The use of information technology to support the business organization's performance is one thing that needs to be done by large-scale industrial sector and small industrial sector (SMEs) to face global competition. As a developing country, the SMES sector in Indonesia is still not fully adopt and utilize information technology (IT) in the business process. Factors of contributors, inhibitors and the effect of the competitive environment and government support will tend to trigger SMEs to adopt IT. This study tries to explore the influence Contributor, Inhibitor, Government Support, and Competitor Pressure, to Technology Readiness (H1, H2, H3, H4), and the Influence of Technology Readiness on Behavioral to Use (H5). The study used 446 valid sample of SMEs of craft industry and being tested using the Partial Least Square (PLS) technique. The testing result shows that the Contributor and Inhibitor have the significant effect on the Technology Readiness with p-value of .000 (<0.05) (H1 and H2 were supported). The testing result of the Technology Readiness on the Behavior to Use also shows the significant result with the p-value 0.00 (<0.05) (H5 was supported). The test of the effect of the Government Support and Competitor Pressure shows the insignificant result with the p-value of 0.81 and 0.53 (>0.05) (H3 and H4 were not supported). Further analysis also found that the Government Support and Competitor Pressure do not affect on the IT users (Behavior to Use) in SMEs. The finding also strengthen the previous claim that the Government Support and the Competitor pressure are not the component which make SMEs ready to adopt and use the IT on their business process.
