Abstract

The data obtained in banking and financial research is often in the form of panel data, while panel data is a combination of cross section and time series data. The aim of this paper is to apply panel data regression analysis to obtain an appropriate model. The case taken is the analysis of the influence of the ratio of Loan to Deposit Ratio (LDR) and Non Performing Loan (NPL) to the Return On Assets (ROA) of Bank for Regional Development (BPD) in Indonesia in the period 2012 to 2016. From the model specification test results obtained that the fit model is the Fixed Effect Model (FEM). The empirical test result between individual and time effect showed that fit model is is individual effect model, i.e. slope coefficients constant but the intercept varies across 20 bank of BPD samples. The main LDR and NPL variables have no significant effect on ROA. While individual Bank BPD which has significant effect on ROA is BPD of DIY, BPD of Central Sulawesi, BPD of Southeast Sulawesi BPD of West Java BPD, BPD of East Java, and BPD of South Kalimantan.

Abstract

Perancangan basis data merupakan proses membuat desain yang akan mendukung operasional dan tujuan suatu instansi. Pemanfaatan basis data pada e-library memungkinkan untuk menyimpan dan men-download e-book ataupun e-journal dengan mudah. Tujuan dari e-library itu sendiri terkait dengan efisiensi biaya penyimpanan fisik dan mempermudah civitas akademika FMIPA Udayana untuk mencari referensi-referensi yang akan digunakan dalam penelitian mereka. Metode yang digunakan dalam merancang basis data e-library adalah metode perancangan basis data relasional sampai dengan bentuk normal ke 3 (3-NF) dan skema basis data yang dihasilkan digambarkan dengan menggunakan SQLyog. Hasil perancangan sistem basis data e-library ini berupa tiga buah tabel yaitu tabel daftaranggota, tabel download, dan tabel katalog yang sudah memenuhi third norm form. Melalui rancangan basis data e-library ini pengguna dapat mengetahui laporan mengenai data mahasiswa yang menjadi anggota e-library, data download, dan data katalog berupa e-book ataupun e-journal yang tersedia, serta dapat mengetahui beberapa informasi lain yang bermanfaat bagi pengguna berkaitan dengan data pada tabel daftaranggota, tabel download, dan tabel katalog.

Abstract

Silat is a class of indigenous martial arts found in some countries in Southeast Asia such as Indonesia, Malaysia, Brunei, Singapore, and south of Thailand. In Indonesia, silat is organised by several silat organisations according to its style (aliran) or school (perguruan). This essay is aimed to study the motivation of playing silat and classify it into its motivational factors by applying confirmatory factor analysis. The data were collected by distributing self-administered questionnaire to 180 members of Perisai Diri at Bali Province, one silat school in Indonesia. Six factors were confirmed as motivational factors for playing silat. These factors, order decreasingly according to their variance explained, are Appreciation of Indigenous Culture, Personal Achievement, Self-Defence, Recreation, Health Maintenance, and Mental & Spiritual Building.

Abstract

Human Development Index (HDI) is a quality measure that can be used to determine the quality of human development that has been achieved. HDI is a composite index that composed of 3 components, such as: Length of life measured by life expectancy at birth, Education measured by average school duration and expectations school duration and standard of living measured by Purchasing Power Parity (PPP) in rupiah. The model used in this research is Spatial Error Model (SEM) to identify Influence of Variables X on IPM value and pattern of HDI distribution in a region with Ordinary Linear Square (OLS) parameter estimates. From the map thematic data that obtained, it can be seen that the pattern of the spread of Human Development Index (HDI) in Maluku Province has no effect on the distance of a region. There is a correlation between the components of HDI compilers to the HDI value in Maluku Province, because there is a spatial dependency on the dependent variable. Lambda value coefficient which is negative and significant at ? = 10% indicates that there is no correlation of HDI value in a region with other adjacent area. Also indicated by spatial residuals in adjacent areas do not have the same characteristics.

Abstract

Weaving industry is one of the creative industries based on local wisdom of Bali, need to be developed with the concept of modern entrepreneurship (orange economy). Regional economic development strategies need to take into account the dynamics of local community life or social capital in addition to the role of government and other physical capital, in order to improve the performance of weaving industry in Jembrana regency, Bali. Based on empirical theory and facts, this study aims to analyze how the direct and indirect influence of the role of government, social capital and business performance on and subjective wellbeing on the business actors of weaving industry in Jembrana, Bali. Through the modeling of the resulting structural equations is studied: (1) the direct influence of the government's role on business performance and subjective well-being; (2) the direct influence of social capital on business performance and subjective wellbeing; (3) the direct impact of business performance on subjective well-being; (4) the indirect and total influence of the government's role on subordinate welfare mediated by business performance; and (5) the indirect and total social capital influences on subjective well-being mediated by business performance. Based on surveys and structured interviews on 70 business actors of weaving industry in Jembrana District, Bali through data analysis techniques using SEM-PLS with the help of Smart PLS 3.0 software, in the business actors weaving industry found that: (1) directly the role of government have positive and significant (2) direct social capital has a positive and significant effect on business performance, but not significant to subjective wellbeing, (3) directly the business performance have a positive and significant effect on subjective wellbeing, (4) the role of the government indirectly has a positive but insignificant effect on subjective wellbeing, but through full mediation of business performance, the role of the government has a positive and significant effect on subjective wellbeing, and (5) social capital indirectly has a positive and significant effect on the subjective achievement, so totally through the full mediation of business performance, social capital has a positive and significant impact on subjective wellbeing although it directly does not have a significant effect.

Abstract

Tourism is a leading sector in developing process of many countries. For Bali, tourism contributes more than 30 percent on the formation of Bali’s Regional Domestic Product. To assure tourism at this island will run in sustainable manner, three aspects have to be considered. This research is aimed to classify the positive as well as the negative effects of socio-cultural dimension arose from tourists activities at coastal area of Badung regency of Bali. A hundred of local community leaders at North Kuta district were selected and their perception regarding effect of tourism on socio-cultural aspect were collected on June – September 2017 and analysed by using factor analysis. Three groups were identified as the positive effects i.e. (a) women empowerment as the economic agents for the family; (b) the increasing of Balinese values; and (c) the raising of community capacity building in developing culture-creative products. Viewed from the burden of cost, we found the potency of increasing the social as well as family conflicts because of different perspectives in viewing tourism.

Abstract

This paper introduces the joint life satatus for married couples with independent and dependent mortality models. Using Frank copula and Indonesia Life Tables 2011, we evaluate the impact of dependent future lifetimes on the net single and level premium. The results show premium rates are reduced if models of dependent future lifetime are used compared to the models using an assumption of independence.
