"[Penelitian ini bertujuan untuk melakukan evaluasi metode Network Breathing sebagai suatu rancangan metode konstruksi jaringan yang adaptif pada komunikasi ZigBee. ZigBee merupakan salah satu protokol komunikasi untuk Wireless Personal Area Network (WPAN) yang dibangun di atas standar IEEE 802.15.4. Karakteristik low power dari ZigBee menjadi salah satu alasan utama dalam pemilihan protokol ini. Suatu metode konstruksi jaringan yang adaptif dapat dirancang untuk mendukung karakteristik ini. Metode ini dimaksudkan untuk membentuk topologi jaringan ZigBee yang senantiasa meminimalkan jumlah router ZigBee yang harus aktif. Metode ini akan menghemat konsumsi energi pada jaringan ZigBee dengan membuat router dalam kondisi tidak aktif ketika tidak ada perangkat akhir dalam jangkauan yang harus dilayani. Rancangan metode ini memiliki prosedur implementasi seperti membentuk jaringan yang bernafas, dan memanfaatkan algoritma shortest path Dijkstra untuk menentukan jumlah minimal dan posisi router yang yang harus aktif sesuai dengan posisi keberadaan perangkat akhir yang harus dilayani. Validasi terhadap rancangan metode ini dilakukan dengan tool perangkat lunak simulasi jaringan NS2, yang menunjukkan penghematan konsumsi energi router hingga 87% tanpa mengurangi kinerja throughput dan end-to-end delay pada jaringan.

This work aims to evaluate Network Breathing method as an adaptive network tree construction method for ZigBee communication. ZigBee is a communication protocol for Wireless Personal Area Network (WPAN) which is built on the IEEE 802.15.4 standard. Low power characteristic of ZigBee is one of the main reasons in the selection of this protocol. An adaptive network tree construction method is designed to support this characteristic. The method is intended to form a ZigBee network topology which always minimizes the number of ZigBee routers to be active. This method will save energy consumption by turning the ZigBee routers to sleep condition when there is no end device within range to be served. The design of this method has implementation procedure such that the network topology acts like breathing, and uses Dijkstra shortest path algorithm to determine the minimum number and the position of routers to be active based on the position of the end devices. Validation to the method is carried out using the NS2 network simulator software tools, which shows reducing in router energy consumption up to 87% without degrading the throughput and end-to-end delay performance.;This work aims to evaluate Network Breathing method as an adaptive network tree construction method for ZigBee communication.

"Saat ini banyak digunakan sebuah jaringan yang dapat mendukung layanan suara, data dan video tanpa adanya downtime, sehingga dibutuhkan back up jaringan serta protokol redundansi (active-standby) untuk menunjang terciptanya jaringan komunikasi yang stabil dan efisien. VRRP dan CARP merupakan salah satu protokol yang sering digunakan untuk mendapatkan level layanan yang tinggi. Rancangan pada skripsi ini akan dibuat dalam beberapa skenario yaitu ping tes, flooding, download dokumen serta streaming dengan parameter RTD (delay time), packet loss, throughput dan waktu failover. Dari hasil simulasi bahwa protokol CARP membutuhkan rata – rata waktu lebih cepat dalam melakukan failover yaitu 5 detik daripada protokol VRRP dengan rata-rata waktu 7 detik. Untuk trafik yang besar protokol VRRP dan CARP mampu melewatkan throughput besar saat dilakukan failover, nilai throughputnya hampir mendekati throughput maksimalnya 6 Mbps, untuk rata-rata packet loss yang didapat sebesar 5-6%.

Today, there are many network could support voice service, data, video conference without any downtime occurred on network. Backup method is required to support all that services and also protocol redundancy (active- standby) which could make a stable and efficient network communications. VRRP and CARP are the frequently used protocols to create a high level of network service. The scheme of this thesis will be made in several scenarios, they are ping test, flooding, download document also streaming by RTD (delay time) parameters, packet loss, throughput and failover time.

The result from simulation showing that CARP protocol need the faster average time that is 5 seconds, but VRRP protocol need 7 seconds of the average time. CARP and VRRP protocol is able to pass up wide throughput while doing failover on the large traffic, its throughput value almost approaches the maximal value of 6 Mbps and average of packet loss are 5-6%."

"Jaringan Mobile IPv6 merupakan teknologi yang mendukung perpindahan mobile node dari titik akses jaringan satu ke titik akses lain tanpa harus memutuskan koneksi. Pada jaringan mobile, perpindahan ini disebut handover yang dibedakan atas vertical handover dan horizontal handover. Untuk mengetahui performa jaringan dengan kedua jenis handover tersebut, dapat diukur beberapa parameter QoS diantaranya adalah throughput, packet loss, dan transfer time. Dalam hal ini, aplikasi yang digunakan berupa download manager yang akan mengunduh file dari sebuah link yang terdapat dalam HMTL file. Hasil pengukuran tersebut bila dibandingkan akan memperjelas perbedaan antara vertical network dan horizontal network untuk kemudian dipelajari berdasarkan teorinya masing-masing. Hasil pengukuran transfer rate, didapatkan bahwa transfer rate pada vertical handover lebih rendah 2,16% dibanding transfer rate pada horizontal handover. Pengukuran packet loss, didapatkan bahwa packet loss pada vertical handover lebih banyak 1831,74% dibanding packet loss pada horizontal handover. Pengukuran transfer time, didapatkan bahwa vertical handover lebih lambat 14,06% dibanding transfer time pada horizontal handover.

Mobile IPv6 network is a technology that supports mobile nodes movement from one location to another within the network without having to disconnect. In mobile networking, the movement is called handover which is divided into vertical handover and horizontal handover. To determine the network performance with both types of handovers, we can measure several QoS parameters such as throughput, packet loss, and transfer time. In this case, application that is used is the Download Manager, which will download a file from link in the HTML file.

The measurement results are compared to clarify the difference between vertical network and horizontal network for further study based on their respective theories. Measurement results of transfer rate, shows that transfer rate in vertical handover is 2,16% lower than transfer rate in horizontal handover. Packet loss measurement shows that packet loss in vertical handover is 1831,74% higher than packet loss in horizontal handover. Transfer time measurement shows that transfer time in vertical handover is 14,06% slower than transfer time in horizontal handover."

AbstractProducts that produced by a manufacturers are to be distributed to retailerthrough distributor. It is necessary to establish a best strategy to distribute theproduct from the manufacturer to the distributor and from the distributor tocustomer in line with customer?s need. Product distribution problem is apparentlya part of the management of supply chain problem.In this thesis, it is described the management of supply chain which canbe divided into two phases. The first phase is how the products produced bymanufacturer are distributed to ditributors. The second phase is how thedistributor distributes the products to retailers. To solve the problem in eachphace, the transportation method is used futhermore, to fine the solution of theentire phases. Bellman Optimizing Principle is adopted. The optimal solutionofthe whole problem is the combination of the optimal solution of each phase."
