Enkripsi dan Dekripsi File dengan Algoritma Blowfish pada Perangkat Mobile Berbasis Android

Cryptography is one of the ways used to secure data in the form of a file with encrypt files so that others are not entitled to know the file is private and confidential. One method is the algorithm Blowfish Cryptography which is a symmetric key using the algorithm to perform encryption and decryption. Applications that are built can perform file encryption-shaped images, videos, and documents. These applications can be running on a mobile phone that has a minimal operating system Android version 2.3. The software used to build these applications is Eclipse. The results of this research indicate that applications built capable of performing encryption and decryption. The results file encryption makes files into another unknown meaning. By using the keys numbered 72 bits or 9 character takes 1,49x108 years to break it with the speed it’s computation is 106 key/sec. Key length and secrecy key affecting the level of security files.Keywords: cryptography, algorithm Blowfish, symmetric key, Android, encryption, decryptionAbstrak - Kriptografi merupakan salah satu cara yang digunakan untuk mengamankan data dalam bentuk file dengan mengenkripsi file sehingga orang lain tidak berhak mengetahui file yang sifatnya pribadi dan rahasia.

Concurrent Quad-band Low Noise Amplifier (QB-LNA) using Multisection Impedance Transformer

A quad-band low noise amplifier (QB-LNA) based on multisection impedance transformer designed and evaluated in this research. As a novelty, a multisection impedance transformer was used to produce QB-LNA. A multisection impedance transformer is used as input and output impedance matching because it has higher stability, large Q factor, and low noise than lumpedcomponent.The QB-LNA was designed on FR4 microstrip substrate with er= 4.4, thickness h=0.8 mm, and tan d= 0.026. The proposed QB-LNA was designed and analyzed by Advanced Design System (ADS).The simulation has shown that QB-LNA achieves gain (S21) of 22.91 dB, 16.5 dB,  11.18 dB, and 7.25 dB at 0.92 GHz, 1.84 GHz, 2.61 GHz, and 3.54 GHz, respectively.The QB-LNA obtainreturn loss (S11) of -21.28 dB, -31.87 dB,  -28.08 dB, and -30.85 dB at 0.92 GHz, 1.84 GHz, 2.61 GHz, and 3.54 GHz, respectively. It also achieves a noise figure (nf) of 2.35 dB, 2.13 dB, 2.56 dB, and 3.55 dB at 0.92 GHz, 1.84 GHz, 2.61 GHz, and 3.54 GHz, respectively. This research also has shown that the figure of merit (FoM) of the proposed QB-LNA is higher than that of another multiband LNA

Vertebra osteoporosis detection based on bone density using Index-Singh statistical blended method

Osteoporosis is a progressive decrease in bone density so that the bones become brittle and broken. Bones are composed of minerals such as calcium and phosphate, so the bones become hard and solid. Many people do not realize that osteoporosis is a silent disease. Therefore, early detection of osteoporosis is very important. Detection of osteoporosis can be done by utilizing x-ray images of the vertebra. In this research the detection of bone density using blended statistical methods and Index-Singh. The x-ray sample used in this research was 50 images of osteoporosis patients. The result of the area calculation yields the highest white pixel is 7,983 pixels and the lowest white pixel is 5,410 pixels. Based on the results of these calculations, a statistical grouping is conducted into 6 Index-Singh. The range of statistical values is 5,410–6,266 pixels grouped into Index-Singh 1, range of data 6,323–6,512 pixels grouped into Index-Singh 2, the data range 6,520-6,747 pixels grouped into Index-Singh 3, data range 6,778-6,998 pixels grouped into Index-Singh 4, data range 7,001-7,219 pixels grouped into Index-Singh 5, and data range 7,338-7,983 pixels grouped into Index-Singh 6. Overall, the results of testing the osteoporosis detection system have been successful and can be used as an early detection system for osteoporosis. This assistance system has a detection accuracy of 76% compared to doctor's justification
