Denpasar as a rapidly growing city needs good traffic (road ways, bridges and traffic lights) inventory. However, in actual fact, at present the government agents in charge are still using graphical data in the form of maps and manual information data (blueprints and paper) which results in various problems. Some of the problems include problems in data storage since the map and information data available at present are saved using paper media which would not last very long and easily damaged, problems in planning the maintenance of road ways, bridges and traffic lights because of the relatively long time spent to check the condition, last maintenance time, and associating acquired data with the maps, which could take half a day (according to the amount of data searched) since the checking of data is done manually and separately (disintegrated) from the information data in the maps. Furthermore, manual data checking has a low level of accuracy, since there could be data skipped in the checking process. To overcome the problem of traffic inventory (road ways, bridges and traffic lights) in Denpasar, a GIS-based System (Geographical Information System) is designed and made in this final project, which could deliver information on road ways, bridges and traffic lights in Denpasar in detail. This system would give solutions to the problems such as digital (softcopy) and integrated map data and information data storage so that the map data will last longer and not easily damaged (not including the condition of force majeure), decision making in planning the maintenance of road ways, bridges and traffic lights could be made faster since the checking of the condition, last maintenance time and map marking is done by the system to the integrated data and takes just a few seconds to complete. Moreover, data checking done by the system will have relatively high accuracy, as there would be no data skipped in the checking process

The voltage applied to the epoxy resin sample at 3.5 kV and 50 Hz frequencyThe experimental results showed that the addition of silicon rubber in epoxy resin makes the surface materialcontact angle increases. The higher percentage of silicone rubber, the greater the contact angle and the longer timerequired for the occurrence of surface discharge.

The growth of the mobile industry is an important aspect in the link of the global village. Another aspect is theInternet. The introduction of VoIP, video conferencing, emailing and TV reviewing also support the communicationbecoming much easier. The Internet becomes a reliable source of information; Users learn more from the Internetthan anywhere else. Therefore, there are many educational institutions publishing their learning material on theInternet. So that e-learning becomes an essential learning method now days. Student can access the learning materialeverywhere, every time. While the mobile industry offers many 3G services, mobile operators still lack of theapplication that allowing users to access learning material while on the move. Mobile learning is an excellentsolution to solve this problem. This will be supported by mobile features improvement, cheaper and faster data rates.This paper gives a simple idea of developing mobile learning where users can access learning material in similarway to blackboard via mobile devices, called blackboard mobile.

Kasus kebakaran yang diduga karena listrik masih sering terjadi. Dari tahun 1991 sampai 2006 kasus kebakaran di Jakarta yang diduga karena listrik mencapai rata-rata 50% dari total kasus kebakaran. Peluang terjadinya kebakaran karena listrik dapat terjadi karena adanya usaha pengurangan kualitas intalasi listrik baik disengaja maupun tak disengaja dan perilaku menyimpang dari pengguna listrik. Adanya peraturan untuk instalasi listrik dan penggunaan peralatan canggih, ternyata masih belum bisa menjamin supaya tidak terjadi kebakaran karena listrik. Semua ini masih dimungkinkan terjadi karena sampai saat ini PT.PLN sebagai pemasok listrik hanya memasang pengukur konsumsi energi (KWh meter) dan pembatas daya tersambung (MCB) saja. Berdasarkan pengalaman dan pengamatan di lapangan, penyimpangan penggunaan instalasi listrik terjadi setelah serah terima pekerjaan pemasangan instalasi listrik, artinya hal ini lebih didasari perilaku pelanggan pemakai listrik. Untuk bisa mengantisipasi perilaku yang kurang baik tersebut perlu dilakukan upaya pencegahan; yaitu dengan menerapkan model sistem intalasi listrik dengan pengaman yang komprehensip. Pada paper ini diusulkan model sistem instalasi listrik yang dilengkapi sistem pengaman terpadu yang dapat mengamankan instalasi listrik secara teknis dan dapat juga diantisipasi perilaku pengguna listrik yang kurang baik dan menyimpang.

Motor arus searah (motor dc), khususnya tipe penguatan terpisah, memiliki karakteristik pengaturan kecepatan yang sangat baik, karena flux-producing dan torque-producing components currents dalam keadaan independen satu sama lain. Hal ini terjadi karena konstruksi fisik motor dc dimana komponen arus yang menghasilkan torsi dan komponen arus yang menghasilkan fluk sudah terdekopel secara alami. Dengan demikian pengaturan kecepatan motor bisa dilakukan dengan teknik pengaturan yang tidak rumit dan tidak memerlukan perangkat keras mahal. Pengaturan kecepatan motor dc bisa dilakukan dengan pengaturan arus jangkar atau arus medan secara bebas dan/atau simultan. Pemilihan variabel kontrol ini tergantung dari daerah operasi dari drive.Untuk pengaturan kecepatan dari diam sampai dengan kecepatan nominal dilakukan dengan pengaturan arusjangkar dimana arus medan dijaga konstan. Sedangkan untuk pengaturan kecepatan di atas kecepatan nominal dilakukan dengan memperkecil arus medan (field weakening). Dalam paper ini akan dibahas modeling pengaturan motor dc penguatan terpisah yang disimulasikan dengan Matlab Simulink.

Network traffic generator can be produced using OPNET. OPNET generates the traffic as explicit traffic or background traffic. This paper demonstrates generating traffic in OPNET 7.0 as background traffic. The traffi generator that was simulated is self-similar traffic with different Hurst parameter. The simulation results proved that OPNET with background traffic function can be as a qualified self-similar traffic generator. These results can help in investigating and analysing network performance for self-similar traffic input

This paper proposes a new approach to estimate the effective bandwidth for self-similar traffic in ATM network. In this approach we use the tail distribution of queue length based on FBM model. This approach is derived from the inequalities for Mills’ ratio. Then a comparison with Norros and Trinh&Miki schemes are analysed. The results demonstrate reasonable agreement between numerical and simulation results and between all schemes. Their bandwidth estimation tends closer for CLP improvement.

Solar cell is an energy conversion that changed solar energy into electrical energy. The energy produced by solar cell is the most energy which safe to the environment, but the area covered of its installation will be very wide. Beside that, solar cell most depends on the intensity of sun radiation, for where its continuity is questionable and become another problem. In order to make solar energy as an electrical power generator, the weakness of the problem should be eliminated. This paper will explain how solar energy could be used as an alternative energy in order to anticipate the electrical crisis in Bali.
