Pengaruh Variasi Jumlah Data Pelatihan SVM Terhadap Unjukkerja Pada Sistem Pengenalan Pola Tulisan Tangan Aksara Jawa Nglegeno

Support Vector Machines (SVM) is one of many classification methods implemented on pattern recognition, including handwritten character recognition system. Numbers of traning set will affect the performance of the recognition system. A basic Jawanessehandwritten character recognition system based on SVM used to show the effect of training set numbers variation on system performance. The experiment result indicating that SVM has good generalization on limiting training set (on a data set, 30% data used for training set can give more than 90% success rate on all data set)

Fenomena Komunikasi Remaja Perempuan Bertato di Pekanbaru

Tattooing is a form of expression of someone who poured through the medium of the body and has a meaning for their owners. the phenomenon of tattoos among women has begun implicated. This is due to a shift in lifestyle that mimics the habit in a big city. Tattooed women in Pekanbaru assume that the tattoo is part of the appreciation of the art form. Most teenage girls with tattoos have a habit of hanging out with friends of the opposite sex until late at night, drinking alcohol, and smoking. Although not all the girls who do it but their behavior gets skewed responses from the public.This type of research uses qualitative method with phenomenological approach. Determination of research subjects and informants using purposive sampling considerations. Activity data collection can be done to no more than ten people informant. Criteria informants in this study were: (1) The informant are young women aged 18 -21 years of age or student and student who tattooed his body. (2) The informant is a citizen pekanbaru. While the object of this research is a phenomenon that appears as experienced by women tattooed in Pekanbaru. Data collection techniques in this research was conducted through observation, interviews, documentation and internet searching. Technical analysis of the data used in this study is a qualitative analysis and be open (open-ended), inductive. The technique of testing the validity of the data using the extension of participation and triangulation.The results of this study indicate the motives of women who have a tattoo is to express themselves, describe something that they love through tattoos. The shape of the tattoo drawn on their bodies is an artistic symbol that represents their motive tattooed on their bodies. The response from the public towards women with tattoos lead to negative stigma and assume women are tattooed wild woman

Jumlah Transisi Pada Ciri Transisi Dalam Pengenalan Pola Tulisan Tangan Aksara Jawa Nglegeno Dengan Multiclass Support Vector Machines

Feature extraction is one of the most improtant step on characters recognition system. Transition features is one from many features used on characters recognition system. This paper report a research on handwritten basic Jawanesse characters recognition system to found the proper numbers of transitions used on transition features. To recognize the characters,the Multiclass Support Vector Machines were used. The Directed Acyclic Graph (DAG) SVM were used for multiclass classification strategy and to map each input vector to a higher dimention space, the Gaussian Radial Basis Function (RBF) kernel with parameter 1were used. It can be shown, for basicJawanesse characters recognition system, the optimal numbers of transitions used for transition features is 4 (a half of maximum numbers of transition on all patterns)

Pengaruh Citra Merek, Kualitas Produk, Dan Promosi Terhadap Keputusan Pembelian Laptop Acer

With the increasing of human population and the growth of sains and technology causing the needing of product of technology becaming the primary needs, especially laptop. Many brands of laptop that available on the market, then there is increasingly intense effort from laptop company to capture large market share from other company. At this time segment of cars that become the market leader in Indonesia is Acer. However the sales of Acer Laptop in 2011-2014 are fluctuated. If it's not addressed it will be a threat to it's dominance on laptop market share.The purpose of this research was to determine the influences of brand image, product quality, and promotion, on purchase decision of Acer Laptop. This research method is explanatory on 100 respondents with purposive technique sampling. With data collection through interview, questioners, and literature review. The analysis technique used was quantitative. Quantitative analysis using cross tabulation, validity, reliability, correlation coefficient, coefficient of determination, simple and multiple regression analysis, as well as the significance test (t test and F test) and helped by application SPSS 16.0 for Windows.The result of statistic analysis known the influences of partially between brand image on purchase decision is 11,8 % product quality on purchase decision is 28,7 %, and promotion on purchase decision is 2,9 %,, the influences of simultaneously between product quality, promotion, and after sales service on purchase decision are 27,3 % whereas 72,7 % affected by other factors.From that results can be concluded brand image, product quality and, promotion influenced to purchase decision partially and simultaneously. Based on these conclusion so advice can be given for the Acer Company are to increasing brand image by increasing the quality of durability of laptop, notice the product quality with increasing the drurablity of laptop by replacing the hardware, doing exciting promotions and increase promotion frequency

Efek Penggunaan Scr Motor Controller Untuk Peningkatan Efisiensi Pada Motor Induksi Tiga Fasa

AC Induction motors are sized for maximum load and are operated at a constant full speed, because they are supplied with power from AC lined at a fixed-sinusoidal voltage and fixed frequency. However, load of motor does not always same at many conditions but the input voltage and power of motor is fixed. Of course, it will influence the efficiency of the motor. One method to improve efficiency of the motor is varying the voltage as loaded its and called Motor Controlled. Motor Controlled is AC Drive that using SCR (Silicon Controlled Rectifier) as the output voltage controller by controlling the firing angle. By employing SCR Motor Controller that adjust the voltage of the motor offers advantageous to improve efficiency of motor and potential for significant energy savings
