"Synchronization of planning and budgeting is a common problem that is often experienced by public organizations in Indonesia, especially in the Ministry of Transportation. The gap in planning and implementation due to this problem is a symptom that the THIS (Thematic, Holistic, Integrative, Spatial) concept has not been able to run optimally and could be optimized through e-government, which does actually not yet reflect the interoperability aspects between each planning application such as e-planning & budgeting; e-performance; e-monitoring & reporting; up to ap2kp (Aplication for Appraisal of Achievement and Calculation of Empoyee Performance). This study uses a qualitative approach with a case study method strengthened by an Analytical Hierarchy Process to examine the application of the electronic-based THIS concept. The results of this study provide policy advices for the preparation of a new ministerial regulation about integrated planning and develop a business process related to the planning flow within the Ministry of Transportation which accommodates the THIS concept."

"Time synchronization is a vital process in wireless sensor networks, where energy sources are highly limited. In this work, we propose a broadcast-based skew correction technique that will improve both the accuracy and the lifetime of any time synchronization protocol that only corrects time offsets among sensor nodes. Using time information transmitted periodically by the root node, each client node can compensate its software clock frequency in real time after an initial offset correction. The experimental results show that a clock skew below 0.05 us/s can be consistently achieved with appropriate compensation parameters after the correction process is stabilized."

"Memristive Nonlinear Electronic Circuits deals with nonlinear systems in the design and implementation of circuits for generating complex dynamics. The brief proposes a new memristor model using an inverse tangent function, which achieves the characteristics of the memristor and can be implemented easily because it corresponds to the bipolar transistor differential pair. The authors design a new model-based memristive time-delay system by obtaining a time-delay memristive differential equation, which can generate an n-scroll chaotic attractor by adjusting the proposed nonlinear function. These designs are carried out using OrCAD-PSpice. The brief also presents a new time-delay memristive circuit excited by a nonautonomous staircase function which can generate grid chaotic attractors: new families of grids of n×m-scrolls."

"Salah satu parameter kinerja manajemen di perusahaan distribusi distribusi adalah nilai SAIFI (System Average Interruption Frequency Index) dan SAIDI (System Average Interruption Duration Index) sistem jaringan distribusi. Nilai ini menunjukkan besarnya kegagalan atau pemadaman yang mengakibatkan pelanggan tidak mendapatkan layanan listrik. Nilai SAIFI dan SAIDI sistem yang semakin besar menunjukkan buruknya unjuk kerja manajemen. Nilai SAIFI dan SAIDI dipengaruhi oleh laju kegagalan (failure rate) sistem jaringan distribusi, yang berasal dari probabilitas kegagalan peralatan-peralatan jaringan distribusi atau probabilitas kegagalan pada titik bebannya. Disisi lain adanya kegagalan atau pemadaman mengakibatkan hilangnya pendapatan dari pelanggan, semakin lama dan sering pemadaman yang terjadi mengakibatkan semakin besar pula kehilangan pendapatan dari pelanggan tersebut. Selain itu pemadaman yang lama dan sering akan bercitra buruk di mata pelanggan dan mengurangi nilai parameter kinerja manajemen untuk pelayanan pelanggan dan ada kemungkinan bahwa perusahaan distribusi harus membayar biaya kompensasi ke pelanggan bila nilainya lebih besar dari TMP (Tingkat Mutu Pelayanan). Nilai probabilitas kegagalan tersebut dapat dikurangi dengan cara melakukan pemeliharaan, yang tentunya memerlukan biaya, semakin lengkap pemeliharaan yang dilakukan, semakin besar pula peluang nilai SAIFI dan SAIDI sistem dapat diturunkan, akan tetapi semakin besar pula biaya pemeliharaan yang diperlukan. Agar efektif diperlukan strategi prioritas pemeliharaan peralatan. Metode perencanaan prioritas pemeliharaan yang digunakan adalah berbasis keandalan sistem dan biaya akibat pemadaman. Peralatan-peralatan yang mendapatkan prioritas utama dalam perencanaan pemeliharaan di GI Plumpang trafo satu untuk empat penyulang adalah PGDB1.A, Trafo3.A, PB3.A, Trafo2.A, Trafo4.A, PB4.A, PB2.A dan Trafo5.A di penyulang Astra1 dan PGDB1.B di penyulang Bibir."

"In post-disaster rehabilitation efforts, the availability of telecommunication facilities takes important role. However, the process to improve telecommunication facilities in disaster area is risky if it is done by humans. Therefore, a network method that can work efficiently, effectively, and capable to reach the widest possible area is needed. This research introduces a cluster-based routing protocol named Adaptive Cluster Based Routing Protocol (ACBRP) equipped by Ant Colony Optimization method, and its implementation in a simulator developed by author. After data analysis and statistical tests, it can be concluded that routing protocol ACBRP performs better than AODV and DSR routing protocol.Pada upaya rehabilitasi pascabencana, ketersediaan fasilitas telekomunikasi memiliki peranan yang sangat penting. Namun, proses untuk memperbaiki fasilitas telekomunikasi di daerah bencana memiliki resiko jika dilakukan oleh manusia. Oleh karena itu, metode jaringan yang dapat bekerja secara efisien, efektif, dan mampu mencapai area seluas mungkin diperlukan. Penelitian ini memperkenalkan sebuah protokol routing berbasis klaster bernama Adaptive Cluster Based Routing Protocol (ACBRP), yang dilengkapi dengan metode Ant Colony Optimization, dan diimplementasikan pada simulator yang dikembangkan penulis. Setelah data dianalisis dan dilakukan uji statistik, disimpulkan bahwa protokol routing ACBRP beroperasi lebih baik daripada protokol routing AODV maupun DSR."

"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."
