Semen glass ionomer merupakan salah satu bahan yang inakan untuk penutupan pit dan fisur guna pencegahan karies i gigi tetap muda. Penggunaan semen glass ionomer, relatif jrhana karena tanpa teknik etsa email. Sebelum pemakaian semen ;s ionomer, permukaan email cukup dibersihkan untuk [hilangkan plak. Dikenal 2 macam cara pembersihan email yakni ira mekanik menggunakan 'rubber cup' dengan pasta abrasif dan ira kimia, dengan pengolesan larutan asam. Penelitian ini ikukan secara laboratorik, guna menilai keefektifan suatu m pembersih email dengan cara membandingkan kekuatan ikatan .1-semen glass ionomer yang diperoleh. Sampel yang digunakan gigi premolar satu atas yang telah dicabut untuk keperluan lodontik. Sebagai bahan pembersih email digunakan pasta :ate dan larutan asam sitrat 50%. Test uji tarik dilakukan ;an alat 'Comten' dan hasilnya dihitung secara statistik :an 'Student t-test'. Dari hasil penelitian, ternyata ipatkan kekuatan ikatan email-semen glass ionomer yang :uat adalah setelah email dibersihkan dengan larutan asam at 50%. Sedangkan kekuatan ikatan terlemah setelah iersihan email tanpa bahan pembersih. Pembersihan email dengan ?a sircate hasilnya tidak berbeda bermakna dengan pembersihan.

This paper explains the development of a parallel computing platform using the available LAN at the Inter University Center for Computer Science of Indonesia. A software toll like parallel virtual machine enables the networked stations to be harnessed as a huge computing resource, combining various type of computing nodes to run parallel computing tasks. The research was aimed at first: to develop a number of parralel high complexity algorithms such as modelling air pollution distribution based on Gaussian Air Pollution Dispersion Formula which simulates dispersion of pollutant emiotted from industrial exhaust and also from vehicle exhaust ont the road. Secondly these algorithms were used to test the platform to obtain networkd behaviour in supporting the implementation of parallel algorithms. From the experiments conducted there are strong indications that the network based computing facility could be used as a suitable platform for running parallel programs with some restrictions. Optimum performance with near linear speed up could be obtained by carefully partitioning the problems, limiting message passing activities and balancing the load of the participating processors.

Osteogenesis depends on the originals cells, which are indirect or endochondral osteogenesis, and direct or intramembraneous osteogenesis. The skeletal of craniofacial consist of bones, group of bones, and cartilages. The function of the skeletal of craniofacial is supported and covered the part of soft tissues in the calvaria. Basically the skeletal ontogenesis of craniofacial same to the other bones which are deposition-resorption, growth field, remodeling, and growth movement. The skeletal osteogenesis of craniofacial controlled by growth sites and growth centers.

Makalah ini menguraikan analisis kinerja jaringan unicast pada saat protokol-protokol SCTP (Stream Control Transmission Protocol) dan TCP (Transmission Control Protocol) berada bersama dalam satu jaringan. Kedua protokol tersebut di ujicoba dengan aplikasi File Transfer Protocol (FTP) dan aplikasi traffic Constant Bit Rate (CBR). Dari simulasi dapat disimpulkan bahwa SCTP mampu mencapai throughput yang lebih tinggi dibandingkan TCP baik pada aplikasi FTP maupun pada aplikasi traffic CBR dengan tingkat fairness, baik intrafairness maupun interfairness; yang cukup tinggi. Peningkatan waktu simulasi menghasilkan nilai kinerja jaringan yang meningkat dan relatif stabil. Peningkatan jumlah sesi pada kapasitas bandwidth kecil menghasilkan peningkatan total throughput dan utilisasi jalur. Hasil simulasi menyatakan bahwa penerapan SCTP dan TCP dalam satu jaringan unicast umumnya dapat dilakukan tanpa menurunkan kinerja jaringan secara keseluruhan dan masih menghasilkan indeks fairness yang tinggi, diatas 0.85 untuk berbagai variasi traffic.

This paper elaborates the performance analysis of a unicast network when two protocols, SCTP (Stream Control Transmission Protocol) and TCP (Transmission Control Protocol) coexist in the network. These two protocols are tested using File Transfer Protocol (FTP) and Constant Bit Rate (CBR) based traffic. From the simulations, it could be concluded that SCTP could achieve better throughput compared to TCP in both FTP and CBR based traffic, with sufficiently high fairness index of both intrafairness and interfairness. The increase of simulation time yields to the increase and relatively stable network performance. The increase of the number of sessions of small bandwidth applications resulted in the increase of troughput and link utilization. The simulations show that implementation of SCTP and TCP in a unicast network generally could be done without having to degrade the network performance, with relatively high fairness index, over 0.85 for various traffic variations.
