Abstract

Development of information technologies is often misused by an organization or a person to take criminal acts, such as the ability to steal and modify information in the data distribution for evil criminal purpose. The Rural Bank of Boyolali is conducting online financial transactions rather intensively, thus it requiring a security system on the distribution of data and credit transactions for their customer among branches offices to head office. The purpose of this study was to build a security system in credit transactions in Rural Bank of Boyolali for their customers among branches offices to head office. One way in protecting data distribution was used XML encryption and XML signature. The application of encryption technique in XML and digital signature in XML by using web service by using the AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman) algorithms. This study was resulted the SOAP (Simple Object Access Protocol) message security system, with XML and WSDL (Web Services Description Language), over HTTP (Hypertext Transfer Protocol) to protect the customers’ credit transactions from intruders. Analysis of examination indicated that the data size (bytes) transferred as results of uncompressed XML encryption were larger than compressed XML Encryption, which leads to significant changes between the data transferred that was the processing time of the compressed data was faster than uncompressed XML encryption.

Abstract

Concrete that used for under water construction need to be proportioned to spread readily and self consolidate.  High Flowable Concrete (HFC) is a kind of High Performance Concrete (HPC) that able to spread readily (flowability more than 50 cm according to BS – 1881). This kind of concrete can be resulted by using higher water/binder ratio or adding some High Range Water Reducer (HRWR) agent. This reseacrh proposed to evaluate effects of water/binder ratio and High Range Water Reducer based on polycarboxylatether (Sika Viscocrete-5) dosage on fresh concrete properties, compressive strength and water absorption of underwater concrete. The research has done with o,40 and 0,45 water/binder ratio and 0.3, 0.6, 0.8, 1.0 and 1.3 percent of HRWR by total wight of binder. 30 cubes (15cm x15cm x15cm) of underwater concrete  were used for absorption examination according to ASTM C-127-68 underwater concrete cylinders (Ø 15cm x 30cm) were investigated for compressive strength in 56 days. Test result indicates that HRWR based on polycarboxylatether could improve flowability up to 3.24 % for 0.4 water per binder ratio and 23.90 % for 0.45 w/c. High Range Water Reducer also improve durability of underwater concrete, indicates by the reduction of water absorption up to 11.11 % for 0.4 water per binder ratio and 18.28 for 0.45 water per binder ratio. Better durability of underwater concrete could be obtained by reducing the value of water per binder ratio that indicated by lower water absorption.

Abstract

This writing aims to give the understanding training method to increase speed. Sprinting speed can be improved although improvement of the very limited speed, because limited by talent. Improvement of sprinting speed can be enlarged by increasing speed support components i.e ; power, anaerobic (speed endurance), flexibility, coordination and skill of run technique. Training of speed better be addressed at improvement of motion frequency by exceeding ability of motion frequency before all. Steps that need to be followed to develop speed consisted of: (1) Basic training to develop all qualities of movement to a level that will provide a solid base on which to build each successive step, (2) Weight training to develop functional strength and explosive movements against medium to heavy resistance. (3) Flexibility and ballistics training. Ballistics to develop high-speed sending and receiving movements, (4) Plyometrics to develop explosive hopping, jumping, bounding, hitting, and kicking, (5) Sprinting form and speed endurance to develop sprinting technique and improving the length of time you are able to maintain speed (6) Sport loading to develop specific speed. The intensity is 85 to 100% of maximum speed, (7) Over speed training. This involves systematic application of sporting speed that exceeds maximum speed by 5 to 10% through the use of various over speed training techniques

Abstract

Perkembangan teknologi otomotif sekarang ini semakin pesat yaitu dengan fasilitas accessories mobil yang semakin lengkap. Namun berbagai fasilitas yang terdapat dalam mobil tanpa disadari menyimpan ancaman bahaya bagi pengguna mobil salah satunya ketika system pada AC (Air Conditioner) terjadi kebocoran maka gas CO (karbon monoksida) akan memenuhi ruang mobil yang tertutup. Gas CO ini sangat berbahaya karena gas ini tidak berwarna, tidak berbau, dan tidak berasa sehingga sulit untuk dideteksi yang dapat menyebabkan orang yang ada didalam mobil menjadi mati lemas tanpa disadari karena menghirup gas CO yang bocor. Dengan fenomena tersebut dibutuhkan sebuah alat yang dapat mendeteksi dan mengontrol kebocoran gas CO untuk memberikan rasa aman kepada pengguna mobil. Alat ini menggunakan kendali logika fuzzy sebagai proses pengambilan keputusan sebagai hasil nilai dari inferensi kerja array sensor. Pengendali utama pada sistem menggunakan mikrokontroller ATmega32. Ketika array sensor yaitu TGS2442 dan TGS2600 mendeteksi kadar gas CO >29,0 ppm berarti dalam status bahaya sehingga buzzer akan aktif diikuti motor DC yang menggerakkan kaca mobil agar terbuka. Berdasarkan lima kali pengujian yang dilakukan didapatkanlah rata-rata selisih error output gas sebesar 0.29 ppm disaat kondisi aman dan 3.87 ppm disaat kondisi bahaya.

Abstract

Non Linear Frequency Modulation (NLFM) method can suppress the peak sidelobe level without additional windowing function. NLFM doesn’t require any weighting function because it has inbuilt one. NLFM has a variable frequency deviation function due to the relation between frequency and time of the signal which is not linear so that it is possible to suppress of peak sidelobe level. This paper studies the characteristic of various NLFM waveform, such as NLFM Tri Stage Piece Wise (TSPW), NLFM S, and NLFM Taylor. The study of Pulse Compression of NLFM waveform consists of three aspects. First, analysis of pulse compression performance. Second, analysis of background noise. Last, analysis of Doppler effects. The simulation is done using Matlab software. The lowest  value Peak Sidelobe Level (PSL)of NLFM TSPW is about -20 dB while NLFM S and NLFM Taylor are about -32 dB and -39 dB. Additive White Gaussian Noise (AWGN) and Doppler Effect influenced the value of PSL for each NLFM waveform. NLFM Taylor has the best NLFM waveform when the Doppler Effect and AWGN cause the value of PSL become high. Comparison between NLFM Taylor and Linear Frequency Modulation(LFM) is done in radar surveillance applications to analyze the detectability performance where the condition of Radar Cross Section (RCS) for each target has different significant value. The three targets are commercial airplanes, helicopter and fighter. For detectability performance, NLFM Taylor can detect more clearly than LFM conventional.
