Abstract

In mathematics, beauty can be thought of as a "certain expectation" for a "natural outcome". Mathematical sciences application have appeared in the field of art, particularly music. One example of its application namely Fibonacci sequence and Golden Ratio. This research aims to create two songs with the Fibonacci sequence and Golden Ratio. The first song were created by applying the elements of the Fibonacci 100% while the second song with the implementation of Fibonacci 64%. Then the sense value ratio from both songs are analyzed using the Wilcoxon test with 16 respondents from ISI Denpasar students (Indonesian Art Institute in Denpasar). This research is expected to add knowledge about the mathematics application to the arts, escpecially the art of music.

Abstract

This research aimed to study the effect of brand image, users’ expectation, and users’ satisfaction  as the determinants for users’ loyalties of Samsung Smartphone by applying Partial Least Square–Structural Equation Modeling (PLS-SEM) method. Data gathered from 100 Samsung smartphone users at Denpasar, Indonesia were collected using questionnaires with 5 Likert’s scales during February–May 2015.  The results showed users’ loyalties was significantly affected by image of Samsung and users’ expectation.  The path coefficients for these causal relationships were 0.533 and -0.230 respectively, demonstrated images’ effect very dominant in forming users’ loyalties.  In addition, products’ image significantly affect users’ satisfaction, but user’s satisfaction did not significantly affect users’ loyalties. The final model had Goodness-of-Fit (GoF) index as much as 0.495 shows the model was sufficient to use for elaborating the relationship between contracts.

Abstract

Hierarchical data are data where objects are clustered in their groups and for each of groups the variable(s) are set at different levels. It is common to analyze hierarchical data without examining individual’s data membership which affects the accuracy of analysis’ results.  Multilevel regression analysis is a method that can be chosen to overcomes issues regarding hierarchical data. This essay is aimed to apply multilevel regression analysis to evaluate score of national examination data from elementary school students at District of South Kuta, Bali.  These data were structured so that students are position as first level and are nested within their classes as the second level.  Furthermore, each of classes is nested within its respective elementary school as third level data. The application of three-level regression for these data set showed student’s score for national final test was significantly affected by teacher educational level of respective class.

Abstract

One of the efforts to develop the rural economy is the establishment of economic institutions such as Village-Owned Enterprises (BUMDes) which are supported by the role of the local government and are based on the wishes of the village community. This BUMDes is expected to be able to increase market demand based on proper management of the existing village potential. Through cooperative behavior (social capital), synergy and a good entrepreneurial orientation in BUMDes managers and the positive role of the government it is hoped that there will be an increase in BUMDes business performance in Jembrana Regency. The purpose of this study is to comprehensively analyze the role of government and social capital of business managers through entrepreneurial orientation towards BUMDes business performance in Jembrana Regency. The basis of multivariate analysis used is Structural Equation Modeling (SEM). Through a research sample of 90 respondents from BUMDes managers in Jembrana Regency, the results are obtained: (1) social capital and the role of government directly have a positive but not significant effect on business performance, while entrepreneurial orientation has a positive and significant effect on business performance, and (2) social capital and the role of the government in a total positive and significant effect and require full mediation (full mediation) through entrepreneurial orientation to the business performance of BUMDes in Jembrana Regency, Bali.

Abstract

Miopia merupakan gangguan penglihatan yang menyebabkan penderitanya tidak dapat melihat objek yang jauh dengan jelas. Fakta menunjukkan bahwa derajat miopia seseorang dapat mengalami perubahan, baik itu meningkat maupun menurun. Peningkatan derajat miopia berbanding lurus dengan potensi terjangkit gangguan penglihatan lainnya, seperti katarak, ablasi retina, dan glaukoma. Oleh karena itu, peningkatan derajat miopia perlu diwaspadai. Beberapa penelitian sebelumnya hanya memperhitungkan faktor waktu dalam memprediksi perubahan derajat miopia. Padahal, perubahan derajat miopia juga dipengaruhi oleh beberapa faktor yang berkaitan erat dengan identitas dan perilaku individu yang bersangkutan. Penelitian ini bertujuan untuk memprediksi perubahan derajat miopia pada manusia berdasarkan beberapa faktor penyebab miopia. Penelitian ini menggunakan data yang telah di-scaling dengan fungsi keanggotaan fuzzy untuk diolah dengan ANN dalam proses memprediksi perubahan derajat miopia. Dengan arsitektur ANN 6-2-3 yang menggunakan 80 data latih, 20 data uji, dan 1 data prediksi, diperoleh hasil prediksi perubahan derajat miopia mata kanan sebesar 1.1 dioptri, mata kiri 1.2 dioptri dan diakumulasi keduanya adalah 2.3 dioptri, dengan persentase akurasi berturut-turut sebesar 87.79%, 78.47%, dan 83.21%.

Abstract

The objective of investment in the capital market is to acquire dividends and capital gain. The fact proves that the advantage of investation risky assets is uncertain . This is because of the difficulty in analyzing and predicting Return and stock losses due to factors that affect the movement of the stock price , such as economic factors , political , social , and security. The model can be used by investors in predicting stock returns expected that Generalized Autoregressive Conditional Heteroscedaticity (GARCH). In this study calculations beta value of some leading stocks in Indonesia by using Generalized Autoregressive Conditional Heteroscedaticity (GARCH) are presented . The data used this search is secondary data covering daily data sampled 5 shares of PT Unilever Indonesia Tbk , PT Indosat Tbk , PT Indofood Sukses Makmur Tbk , PT Telkom Indonesia Tbk , PT Holcim Indonesia Tbk. From the results described fifth beta value of these shares using the method GARCH beta greater than the market in the period from 23 September 2013 until 24 September 2014.
