The reference of QoS standard is the standard issued by ETSI (European Telecommunications Standards Institute) and ITU (International Telecommunication Union). The use of queuing scheme is also effective for reducing the value of delay and jitter for video and VoIP services, as proven in the graph that looks down from the beginning to the end. The WFQ queue scheme overall has the best QoS value, which means it provides weight with 50% on the video, 40% on the VoIP, and 10% on FTP proved effective for the design of topology and configuration in these research. Results all of queuing scheme such as FIFO, PQ, and WFQ queues generally satisfy of the QoS standards issued by ETSI and ITU, but delays in VoIP services have more value than the preferred standards but still far from the limit standards. Keywords: WAN, QoS, FIFO, PQ, WFQ ABSTRAK: Penelitian ini mengimplementasikan beberapa skenario skema antrian, yaitu FIFO ( First in First Out) , PQ (Priority Queuing) dan WFQ ( Weighted Fair Queuing) pada router yang terhubung dengan jaringan WAN . Simulasi dilakukan menggunakan OPNET Modeler 14.5 dengan topologi jaringan WAN yang menghubungkan Data Center dengan beberapa user atau client yang berbeda kota, untuk mengamati parameter QoS seperti packet loss, delay , dan jitter pada layanan multimedia seperti FTP, video , dan VoIP. Standar QoS yang menjadi acuan adalah standar yang dikeluarkan oleh ETSI ( European Telecommunications Standards Institute ) dan ITU ( International Telecommunication Union ). Penggunaan skema antrian juga efektif menurunkan nilai delay dan jitter pada layanan video dan VoIP, terbukti pada grafik yang terlihat menurun dari waktu awal ke akhir. Secara keseluruhan skema antrian WFQ memiliki nilai QoS yang paling baik, yang berarti pemberian bobot konten paket 50% pada video , 40% pada VoIP, dan 10% pada FTP terbukti efektif untuk perancangan topologi dan konfigurasi yang dibuat. Hasil skema antrian FIFO, PQ, dan WFQ secara umum sudah memenuhi standar QoS yang dikeluarkan oleh ETSI maupun ITU, namun delay layanan VoIP memiliki nilai sedikit diatas standar istimewa tetapi masih jauh dibawah dari standar limit yang ditentukan.

Block cylinder is made from cast iron material (FC 230) which must be melted with temperature >1400 ° C. The temperature of cast iron molten metal into the mold is a very important factor to guarantee final quality of block cylinder. Process pouring of molten metal into a mold using a ladle to pouring 15 molds. Pin hole defects often occur in the final castings, this is due to molten metal temperature drop at the end, the one factor is air convection suction smoke collector. Smoke collector is required to move the gas that arises during the pouring process to outside the factory in order to make a comfortable and healthy work process, but it has side effect speed up decreasing temperature of molten metal. To solve the decrease temperature is minimize the rate of heat transfer that occurs from molten metal to environmental air. One way is to close the ladle with the cover to reduce the heat transfer that occurs in the metal liquid. The material used as a ladle cover is Kaowooltm SZr, where it has low thermal conductivity and light density. The rate of heat transfer occurring in the metal liquid to the surrounding air without cover is 4,5563 kW. After using the ladle cover the rate of heat transfer from metal liquid to air decreases to 1.8287 kW.
