Abstract

Integrated Circuit Card or commonly named as smartcard is a properiatery devicewhich is based on ISO/IEC 7816 standard. In order to expand smartcard capabilities andinteroperabilites, PC/SC Workgroup defines a specification on interoperabilities between PCand smartcard. With this specification, which also has been implemented by Microsoft asWin32 API, one can develop applications which is using smartcard as small amount datastorage (identification key, password, or else).Smartcard-based applications can be developed in Windows operating systemenvironment easily by using Win32 API library, user interface library or Win32 COM library.The application development itself can be done by using Microsoft Visual C++ or MicrosoftVisual Basic.Keywords: ICC, smartcard, interoperable, PC/SC workgroup, win32

Abstract

Encryption is one of the most important components in security of application ofinformation technology. We need the good knowledge of encryption attack, to create thestrong, rapid, and flexible encryption algorithm. This research shows that security ofencryption algorithm does not only depend on the bits number of key, but also depend on thestructure of algorithm itself. The more complicated the algorithm is (it is hoped more secure)the slower the algorithm runs, so the algorithm is not comfortable to be used. This researchincludes cryptanalysis and programming to attack the algorithm of simple encryption, 80-bitkey, which can be broken theoretically in 19 years using 1 million computers, with brute forceattack. In this research, this algorithm can be broken less than one minute with 10 thousandcharacters of known plain text with one personal computer, although the algorithm has goodstatistical property.Keywords: encryption, cryptanalysis, brute force attack, statistical property, known plaintext

Abstract

The continuous increment of mobile communication subscribers, require a highercapacity and spectrum efficiency of the cellular system especially in an urban area where thetraffic density is high. In order to accommodate the increasing number of subscribers, smartantenna technology is used to improve system’s performance, which could increase thenumber of call and data transmission as well as simplifying the networking management. Thebasic principle of a smart antenna is to control and reduce the effect of interference toprovide the user with the highest quality of uplink and downlink signal. This can be achievedby using narrow beams with signal processing capability at the base sites and to optimize itsradiation pattern, which automatically updated according to MS movement or as signalsconditions change. In this study, two types of smart antenna were considered, which are theswitched beam systems and adaptive antenna systems. The significant difference betweenthese two systems is from the beamforming point of view. The key part of this study is todevelop a simulator for adaptive antenna systems (AAS) and switched beam systems (SBS)based on GSM 900 in order to determine the factors that could affect network’s quality andcapacity. Simulation results of different techniques are compared and the performanceevaluations of C/I are discussed. Results show that the AAS gives a better performancecompared to SBS, with average improvement of C/I around 5 to 10 dB.Keywords: smart antenna, adaptive, switched beam,C/I

Dilain pihak, pengambilankeputusan ini sering sangat sulit untuk menentukan apakah manfaat nyata apabila melakukaninvestasi dibidang teknologi informasi dalam sebuah organisasi. Tulisan inimempertimbangkan pertanyaan ini dalam ruang lingkup industri pariwisata, yang sangattergantung pada penggunaan teknologi informasi dalam kegiatan operasionalnya seharihari.Lebih khusus, penelitian ini menginvestigasi hubungan diantara investasi teknologiinformasi, penggunaan teknologi informasi, kepuasan pengguna komputer, kinerja penggunakomputer dan kinerja hotel.Sebuah survey terhadap 945 EUC (computer end-user) yang bekerja di beberapahotel di Bali, Indonesia telah dilakukan untuk menilai persepsi mereka tentang dampakteknologi informasi pada sebuah organisasi. Hasilnya menunjukkan bahwa ada hubunganyang signifikan diantara kelima variabel yang diinvestigasi. Lebih lanjut, telah diketemukanbahwa level investasi dibidang teknologi informasi dan level kinerja user secara langsungdapat mempengaruhi kinerja hotel, akan tetapi jumlah penggunaan teknologi informasi danlevel kepuasan user dapat mempengaruhi kinerja hotel secara tidak langsung melalui levelkinerja user. Dilain pihak, kepuasan user juga diketemukan memiliki pengaruh yang sangatkecil terhadap kinerja hotel. Level investasi dibidang teknologi informasi memiliki hubunganyang signifikan dengan level kepuasan user, dimana diketemukan pula secara langsungmempengaruhi jumlah penggunaan teknologi informasi. Yang tidak kalah penting adalahinvestasi dibidang teknologi informasi diketemukan memiliki pengaruh secara langsungterhadap penggunaan teknologi informasi dan kinerja user di beberap hotel. Penemuan inimenyarankan bahwa generalisasi di beberapa organisasi yang akan melakukan investigasipengaruh investasi teknologi informasi terhadap kinerja organisasi, dan hal ini tidak dapatdiabaikan.Kata kunci: information technology, organization performance, hospitality industry.

Abstract

This paper presented computer programming of concrete mix design used Microsoft®Visual Basic™: NCMD. The procedures use by this computer program are based on SKSNIand ACI method of concrete mix design. The method was developed for use with cement,aggregates, and water, which conform to the relevant Indonesian and American standard.However since this standards lay down requirements which materials must meet in order tobe suitable for good quality concrete, the procedures of SKSNI and ACI method can beapplied to concrete mix design generally. The object of this computer program is to find theproprotions in which the concrete material - cement, water, fine aggregate, and coarseaggregate - should be combined in order to provide the specified strength, workability,durability, and possibly meet other requirements, as listed in standard such the SKSNI andACI standard.Keywords: mix design, concrete, computer programming, visual basic™.
