"Model is a representation of a system. Through model, it can be easier to forecast and control the changing of each element system. Electricity distribution is also a system. Losses are general problem that exist in a distribution network system. But with the right methods, specifically technical energy losses can be reduced in order to increase the efficiency. By making model of the distribution network, the value of technical energy losses in the whole network as well as in every line can be observed. Simulation can also be used to see all losses reduction alternatives. By comparing results from each alternatives, the best alternative, which gives best result can be decided and implemented."

"In this study we discuss how to handle DDoS attack that coming from the attacker by using detection method and handling mechanism. Detection perform by comparing number of packets and number of flow. Whereas handling mechanism perform by limiting or drop the packets that detected as a DDoS attack. The study begins with simulation on real network, which aims to get the real traffic data. Then, dump traffic data obtained from the simulation used for detection method on our prototype system called DASHM (DDoS Attack Simulation and Handling Mechanism). From the result of experiment that has been conducted, the proposed method successfully detect DDoS attack and handle the incoming packet sent by attacker.Dalam paper ini dibahas bagaimana menangani serangan DDoS yang datang dari penyerang dengan menggunakan metode deteksi dan mekanisme penanganan tertentu. Deteksi dilakukan dengan membandingkan jumlah paket dan jumlah aliran. Sedangkan mekanisme penanganan dilakukan dengan membatasi atau menjatuhkan paket yang terdeteksi sebagai serangan DDoS. Penelitian diawali dengan simulasi pada jaringan yang nyata, yang bertujuan untuk mendapatkan data lalu lintas real. Kemudian, dump data lalu lintas yang diperoleh dari simulasi yang digunakan untuk metode deteksi pada sistem prototipe kami disebut DASHM (DDoS Attack Simulation and Handling Mechanism). Dari hasil percobaan yang telah dilakukan, metode yang diusulkan berhasil mendeteksi serangan DDoS dan menangani paket masuk yang dikirim oleh penyerang."

"The Three-Volume-Set CCIS 323, 324, 325 (AsiaSim 2012) together with the Two-Volume-Set CCIS 326, 327 (ICSC 2012) constitutes the refereed proceedings of the Asia Simulation Conference, AsiaSim 2012, and the International Conference on System Simulation, ICSC 2012, held in Shanghai, China, in October 2012. The 267 revised full papers presented were carefully reviewed and selected from 906 submissions. The papers are organized in topical sections on modeling theory and technology, modeling and simulation technology on synthesized environment and virtual reality environment; pervasive computing and simulation technology, embedded computing and simulation technology, etc."
