Abstract

At this time, the players Forex Trading generally still use the data exchange in the form of a Forex Trading figures from different sources. Thus they only receive or know the data rate of a Forex Trading prevailing at the time just so difficult to analyze or predict exchange rate movements future. Forex players usually use the indicators to enable them to analyze and memperdiksi future value. Indicator is a decision making tool. Trading forex is trading currency of a country, the other country's currency. Trading took place globally between the financial centers of the world with the involvement of the world's major banks as the major transaction. Trading Forex offers profitable investment type with a small capital and high profit, with relatively small capital can earn profits doubled. This is due to the forex trading systems exist leverage which the invested capital will be doubled if the predicted results of buy / sell is accurate, but Trading Forex having high risk level, but by knowing the right time to trade (buy or sell), the losses can be avoided. Traders who invest in the foreign exchange market is expected to have the ability to analyze the circumstances and situations in predicting the difference in currency exchange rates. Forex price movements that form the pattern (curve) up and down greatly assist traders in making decisions. The movement of the curve used as an indicator in the decision to purchase (buy) or sell (sell). This study compares (Comparation) type algorithm kernel on Support Vector Machine (SVM) to predict the movement of the curve in live time trading forex using the data GBPUSD, 1H. Results of research on the study of the results and discussion can be concluded that the Kernel Dot, Kernel Multiquaric, Kernel Neural inappropriately used for data is non-linear in the case of data forex to follow the pattern of trend curves, because curves generated curved linear (straight) and then to type of kernel is the closest curve similar to the curve trend of online forex trading is Anova kernel and kernel radial, a little closer Combination Gaussian kernel, kernel Epachnenikof and to kernel polynomial form a parabolic curve open. key words: Trading Forex, Support Vector Machine, Kernel Anova, Dot Kernel, Kernel Multiquaric, Kernel Neural, Prediction, radial Kernel, Kernel Gaussian Combination, Epachnenikof kernel, polynomial kernel, EURUSD H1

Abstract - Health Safety and Environment (HSE) in the development will be more accentuate on the prevention of occupational accidents and occupational diseases by identifying the potential to cause accidents and occupational diseases as well as anticipatory measures in case of accidents and occupational diseases. The working environment is directly in contact with toxic materials would be very harmful to the human body when exposed continuously. An environment or factory containing toxic gases as an example of CO, SO or LPG gas in certain concentrations can cause eye irritation or shortness of breath. Therefore we need an early warning system that can measure the concentration of these gases and may give a warning to workers associated with the concentration of the gas to the workers. The early warning system was made using three gas sensors, three heat sensors, LEDs and buzzer. Recitation and processing of the sensor is processed by a 16 bit microcontroller which will condition the room. In making such a system is used programmable fuzzy algorithms previously simulated with MATLAB, C Programming used as logic programming refers to the simulation results, miniature rooms created with three main space for workers in a hallway and an emergency exit. The results of such a system is in a room when the detected gas concentration exceeds the threshold, the system will activate the buzzer and will activated LED as the safest evacuation route directions.

Abstract

There are many examples based on the modernity of technology however, which affects the life (and especially thoughts and views) community and Muslims in this age is social media. If at some previous period, social media use newspapers, radio, television, wire, and other simple equipment, so today has been converted into a more easily with the technology. The most feared consequence is that social media would be more likely as a tool to launch a variety of ideas that will be largely irrelevant, and destructive to the lives according to the law, religious teachings and norms that berlaku.Oleh therefore, we should know more restrictions -batasan that 'should' in the air-the social media, the community and our people will not fall more deeply to the things that are provocative, ambiguous, confusing, and all the things that lead to moral decay and the mindset of the people.

Abstract

Pada sistem pengendali konvensional dan pengendali digital digunakan sinyal analog/ kontinyu dan sinyal diskret. Untuk menganalisa sistem pengendali konvensional digunakan persamaan dalam bentuk transformasi laplace, sedangkan dalam analisa pengendali digital digunakan transformasi z. Berbeda dengan pengendali fuzzy logic atau pengendali cerdas lainnya yang tidak membutuhkan model matematis, sehingga tidak diperlukan analisa menggunakan transformasi laplace atau transformasi z. Transformasi laplace banyak digunakan untuk menyatakan fungsi alih sistem kendali konvensional, sedangkan transformasi laplace balik (inverse laplace) digunakan untuk mendapatkan kembali fungsi alih dalam kawasan waktu. Transformasi z yang banyak digunakan pada pengolahan sinyal digital yang merupakan bagian dari sistem kendali digital. GUI Matlab dapat digunakan untuk membantu proses perhitungan transformasi sinyal, yaitu transformasi laplace, transformasi laplace balik, transformasi z, dan transformasi z balik. Untuk menentukan karakteristik suatu sistem digunakan pemodelan. Dengan menggunakan fasilitas simulasi program Matlab (simulink) dapat membantu untuk merancang simulasi suatu model, baik model yang bersifat linear maupun yang tidak linear. Dengan simulasi dibutuhkan waktu yang singkat dan biaya yang tidak terlalu besar jika dibandingkan dengan eksperimen menggunakan alat. Simulink merupakan bagian dari Matlab yang digunakan untuk mengamati dan menganalisa karakteristik dari tiruan sistem. Dalam penelitian ini simulink sangat membantu dalam memahami konversi sinyal dari sinyal analog menjadi sinyal diskret, dengan mengatur perubahan waktu pencuplikan atau sampling. 0.2 detik dan 0.5 detik.
