    The recent technology of the television is implementation the digital system over transmitter, transmission channel and receiver. Therefore, television system in Indonesia is dominated by analog system, that less flexible for system development and communication on digital communication system. So that, it need actions to develop the digital broadcasting system to replace the analog broadcasting system. Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The limited channel capacity endorse to save all aspect on the telecommunication system. There are some research on audio signal coding to obtain the lower bit rate for transmission channel usage saving. The audio signal is processed, so that the redundant component can be decreased, then we obtain the simple size of information that reliable to be transmitted. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research will be done is develop an audio signal coder on the low bit rate with the suitable decoder. The decoder consists of the parameters detector, signal synthesizer, and the periodic signal generator. The encoder and the decoder development is implemented using C++ software. The hardware for the simulation process consists of microphone, digital signal processor and the personal computer equiped with sound card for audio signal acquisition

    Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research will be done is develop an audio signal coder on the low bit rate with the suitable decoder. The proposed audio signal coder consists of signal existention detector, period width detector, average amplitude counter, separation of the vibrating and the nonvibrating signal, determination of the period signal and parameters coding. One period signal is coded using sinusoidal model. The decoder consists of the parameters detector, signal synthesizer, and the periodic signal generator. The research results contribution for digital broadcasting is the method developing for decreasing the audio signal rate. So that the communication channel usage can be saved

    Economic model assumes that an individual committing crimes is rational because the income which is generated through illegal occupations has greater expected utility than the legal. The expected utility which is the result of cost-benefit analysis will be weighted whether if illegal or legal occupations committed or not. Therefore, some experts developed supply of offense function as economic model, which indicates the factors affecting the total number of crimes as empirical study. The application of supply of offense function supported with multiple linear regression function, the factors affecting the total number of crimes in Indonesia have following results: wage rate variables indicated a negative and significant result and government expenditure variables indicated positive and significant result, but the imprisonment rate variables did not have significant result with the total number of crimes in Indonesia

    The purpose of this study was to analyze the significance of the effect of trust, security, quality of service and the perception of risk on purchasing decisions through social networking sites. In conclusion: There was a significant effect of trust on purchase decisions through social networking sites on college students in Surakarta. There was a significant influence on the purchase decision security through social networking sites on college students in Surakarta. There was a significant effect of service quality on purchasing decisions through social networking sites on college students in Surakarta. There is a significant effect on the perception of the risk of purchasing decisions through social networking sites on college students in Surakarta. F test analysis results it is concluded that the model used to test the effect of the independent variables are trust, security, quality of service, and the perception of risk to the dependent variable is the purchase decision through social networking sites on college students in Surakarta is right. The results of the analysis of the value of the coefficient of determination obtained Adjusted R Square = 0,535 means known that the influence exerted by the independent variables are trust, security, quality of service, and the perception of risk to the dependent variable, namely purchasing decisions through social networking sites on college students in Surakarta for while the remaining 53,5 percent

    Stabilization of domestic currency exchange rate towards international currency especially US Dollar is important part of macro economy policy. This policy always is strived for a government in good certain time period in short-run or long-run. Based on discussion in this paper, there are some factors that can be source the happening of rate fluctuation. Theoretical, financial market variables and riel macroeconomic variables are the important factor that can influence rate fluctuation. Some of the variables are interest rate, money supply, financial liberalization, domestic and international price, productivity, government expenditure, and employment. Meanwhile, the result of empirical study by Daly (2006) indicated that riel macroeconomic variables were obvious more important role in influencing rate fluctuation movement at amount of country

    This study aims to provide a description of the visual aesthetics contained in the show Puppet Theater Petta Puang in South Sulawesi in connection with the network of symbolic meaning inherent in it. The method used is descriptive-interpretivime method symbolic, with data collection techniques through direct observation, interviews, and documentation. The result of the research shows that in the performance of Petta Puang Puppet Theater there is a visual aesthetic that characterizes the main character «Petta Puang» in every appearance that is jas tutup, songkok guru (songkok to Bone), and lipa ‘sabbe\u27. Some visual aesthetics have symbolic meaning directly related to the socio-cultural values of the people of South Sulawesi. Lipa ‘sabbe (silk sarong) is a Bugis sarong which has a fine texture as a representation of the tenderness and social politeness of Bugis tribe, while vertical and horizontal lines are markers of human relationship with God and human relationships in the social system. Jas Tutup originally consists of two colors, namely black and white. Two elements of color is a neutral color that confirms the impression of depth and sanctity that became the patron of Bugis tribe values

    Seam carving is a method of content aware image resizing. As solutions shortest path algorithms are used to find images seams. Seam is a horizontal or vertical path of an image that has minimum energy. There are two (2) shortest path algorithms that will be discussed in this paper. This paper contains the results of shortest path algorithms comparison between Dijkstra and Directed Acyclic Graph to see which one is better than another in case of efficiency. The precomputed and recomputed methods will be compared to find the more efficient method for executing the seam carving transformation. A web application has been built for this purpose. This web app is capable of transforming image size with seam carving method. The complexity of Dijkstra and Acyclic will be compared to find which one is better. The result is Dijkstra has been won, with the O(4V) with Acyclicis O(5V). The use of precomputed and recomputed is evaluated by the conditions. If the preparation is evaluated then recomputed is more efficient, but if the preparation is not evaluated then the precomputed method is the better one and has faster performance
