Abstract

This paper discusses the application of solar cell (solar cell) as a power plant with solar energy source. The electricity generated is used as the Hanphone Charger. The working principle of a solar power plant is from sunlight that contains energy in the form of photons. When this photon concerns the surface of the solar cell, its electrons will be excited and generate electrical voltage. The electric current generated from the solar cell is the direct current (DC) as the battery charger, which is then the DC (DC) current output of the 12 Volt battery is lowered to 5 Volts and becomes an alternating current (AC) using an inverter. The testing stage is carried out in the installation field with test parameters such as voltage and electric current. The battery is filled by solar cells as a result of converting solar energy into electrical energy. The resulting voltage of the solar cell ranges from 14.8 - 17.5 volts DC. Solar cell used in the form of panel type Policristal (Poly-crystalline) with 50 wp power. At the current and voltage distribution from the solar cell source, although the voltage generated by the solar cell is ± 17V, but when the battery is very stable with an average voltage of 13.5V as regulated by solar charger controller. Voltages and currents will begin to increase in the morning at 07.00 WIB, then will reach the maximum level during the day at 10:00 to 13:00 pm, and began to fall in the afternoon.

Abstract

The increasing development of data communication technology is certainly directly proportional to the security and data confidentiality aspects. There are some ways to protect information from unauthorized parties. Some of these ways are using steganography techniques and cryptographic techniques. Nowadays steganography technique is commonly used, so it still allows the inserted secret information is solved by other parties. This problem may reduce the level of data security and confidentiality. To overcome these problem, in this study steganography techniques will be combined with cryptographic techniques. Design of the built system is done by combining the application of Rivest-Shamir-Adleman (RSA) cryptography algorithm in encrypting the message on application of the image steganography method in concealing the encrypted messages generated into a color image (RGB) on the Discrete Wavelet Transform (DWT). The results to be obtained from this project is an image that has an encrypted message on the subband frequency of the image. Based on some tests that have been done on the system, the result of average performances score is showed by Avalanche Effect of 43,486%, Peak Signal to Noise Ratio (PSNR) of 67,2755%, Bit Error Rate (BER) and Character Error Rate (CER) of 0%. The conclusion is, the implementation of a combination between RSA cryptographic methods and steganography of DWT transformation image is successfully performed.

Abstract

trocardiogram (ECG) is a medical test to detect heart abnormalities by measuring the electrical activity produced by the heart, as the heart contracts. ECG can help diagnose various health conditions such as cardiac arrhythmias, heart enlargement, heart inflammation (pericarditis or myocarditis), and coronary heart disease. In general, detection of heart disease can only be done in a hospital using ECG. The system that is used now also cannot be used to automatically detect the patient's illness when using the ECG. In this paper the author makes a tool that can detect portable heart signals. From the detected heart signal we can determine that the heart's condition is normal or there is an abnormality in the heart. The heart signal was detected from the electrode clamp sensor mounted on the right arm (RA), left arm (LA) and right leg (RL). The signal from the sensor is amplified with an amplifier amplifier circuit so that it can be read by the STM32F4 ARM microcontroller. The microcontroller processes the signal from the sensor and will be displayed on the Computer Application. Connection between Microcontroller and PC using a Bluetooth serial connection. The final appearance in this final project can display the shape of the ECG signal and determine that the heart is normal or abnormal. Based on the test results obtained from the comparison of ECG devices made with the ECG type BTL-08 SD there is an error of 1.06%.
