Abstract

Sistem dinamik dapat dikembangkan dalam berbagai bidang kehidupan.Seperti dalam bidang ekonomi, salah satu sistem dinamik dalam bidang iniadalah model siklus bisnis. Ada beberapa model siklus bisnis, diantaranya modelIS-LM. Dalam penelitian ini akan dianalisa model siklus bisnis IS-LM dengan parametertime delay. Perbedaan antara keputusan investasi dengan implementasinyamenganjurkan untuk merumuskan model siklus bisnis IS-LM yang baru, yang memperlihatkanbahwa dinamika model sangat bergantung pada parameter time delay(waktu persiapan periode investasi). Dalam penelitian ini akan digunakan teoremabifurkasi Hopf untuk memprediksi kejadian dari limit cycle untuk parameter timedelay, yang menggambarkan siklus dari model IS-LM.

Abstract

The main goal of every company in business is the optimal profit. Challenges that often faced by companies in achieving maximum profit is the difficulty of combining every available resources of the company. The purpose of this study was to determine the maximum profit that can be obtained by Ls Garment using the simplex method and determine the impact of the changes that occur in the objective function coefficients and constants right side constraints to the optimal solution. Based on the results of the application method used, it was obtained maximum profit of Rp. 1.893.184,00 per day with the amount of Dress Payung, Celana Aladdin XL, Celana Aladdin XXL, Celana Aladdin ¾, Dress Kerut, and Daster Haji respectively are 34, 60, 68, 96, 26, and 26 pieces. Profit remain in optimal condition if the change of coefficients value at the objective function is less than or equal to the coefficient of the objective function at the initial model.

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

Nadir Compromise Programming (NCP) is one of method that can be used to solve multiobjective problem using certain parameter. One of the problem that can be solved by these method is to get the optimum value of stock portfolio. The purpose of this study was to determine on what value of parameter among six values of parameter, NCP models effective in determining the optimum value of the stock portfolio. The data used in this research was secondary data in the form of daily data from the price of 6 types of stocks from October 2013 to October 2015. In this study, the optimum value of the stock portfolio was calculated by the the NCP model at 6 parameter values, i.e. 1, 10, 100 , 1000, 10000, and 100000. As a result of this study showed that the NCP model effective in determining the optimum value of the stock portfolio on parameter 1.

Abstract

Tourism has been positioned as rising industry since year 2000s. Despite of its position as the primary mover for economic development and increasing the welfare of local people at the destination, tourism also induces some negative impacts regarding the social as well environment dimension for the destination and its surrounding. This essay is directed to study the impacts of marine tourism that take places at coastal region of Badung regency of Bali province. Utilising proportionally random sampling, 180 local people at District of Mengwi at Badung were selected as the sample's members for the study. Three dimensions of tourism sustainability i.e. economic, socio-cultural, and environment dimension were positioned as the exogenous latents while tourism impact was perceived by the local is placed as the endogenous one. In additon, this impact is hypothesed a ects the sustainability of marine tourism at this district. A covariance-based structural equation model was built to elaborate the causal relationship among these latent variables. Our research confirmed all of exogenous latents significantly affect people perception about tourism impact with socio-cultural dimension dominates the others' impact, and in turn, this impact - from supply perspective - affects marine tourism sustainability at Mengwi district of Badung regency.

Abstract

Distribution activities in company which related in distribution sometimes have a problems, one of the problems is transportation problem. To solve that problem can be used a transportation model to obtain the distribution route so the cost that come out is more minimum. The aim of this research is to compare the initial solution of RAM and IVAM and to know the distribution route in distribution of bottled water in the CV. Prasarana Fortuna Prima so obtained the minimum distribution costs after optimality test using MODI. The results showed that RAM gave a lower initial solution than IVAM and the initial solution of RAM was optimum after optimality test using MODI with a distribution routes is from depo Klungkung to Toko Bintang, Toko Subur, Toko Cahaya Melati, Toko Mawar Sari, and Coco Mart Ubud, from depo Kapal to CV. Sumber Jaya, Toko Sol Mandala, and Toko Kayana, from depo Mahendradatta to Toko Sinar Wangi and Toko Aris.

Abstract

The purpose of the study is to forecast the price of rice in the city of Denpasar in 2017 using backpropagation neural network method. Backpropagation neural network is a model of artificial neural network by finding the optimal weight value. Artificial neural networks are information processing systems that have certain performance characteristics similar to that of human neural networks. This analysis uses time series data of rice prices in the city of Denpasar from January 2001 until December 2016. The results of this research, concludes that the lowest rice price is predicted in July 2017 at Rp9791.5 while the highest rice price in April 2017 for Rp9839.4.
