Modeling and Simulation of Hybrid Generator of Photovoltaic, Genset and Battery

In Proc. of the 2013 International Workshop on Modern Research Methods in Electrical Engineering (IWORMEE 2013)Electrical power system generating from renewable energy sources especially solar and conventional power plants such as the generator is designed as an educational model for the public to understand how the hybrid system can generate electrical power as a unified system. This paper is aimed to investigate the hybrid system performance between photovoltaic, genset and battery as well as the system units, so that they could work as an integrated system in generating the electric power. This is a descriptive paper with simulation approach. Simulation parameters were obtained through data documentation of the photovoltaic, genset, battery and Solar radiation intensity, they were input into a Simulink/Matlab simulation program. The simulation model parameters created were adjusted with the unit component characteristics of the existing generator in the Laboratory. The results obtained from the simulation indicates that if the photovoltaic and battery power can still serve the load, the genset will be "off" or vice versa. The power magnitude generated by photovoltaic is 110.17 Watts at 0.88 kW/m2 solar radiation, whereas the power magnitude of the genset is 98.08 Watts on the lap of 350 rad/sec. At 31.78 and 55.79 hours and 67.70 hours until 70.04 hours of 72 hours simulated, the power supply decrease occurs from the generator. This can be overcome by using a larger battery capacity

Analisis Karakteristik Spasial Kota Pare-Pare Berbasis GIS dan Remote Sensing Menggunakan Citra Landsat 8

Perkembangan teknologi informasi pun berkembang sangat pesat hingga sekarang ini sehingga masyarakat akan lebih mudah untuk dapat mengakses informasi. Sistem Informasi Geografis (SIG) atau Geographic Information System (GIS) merupakan sistem informasi berbasis komputer yang digunakan untuk mengolah dan menyimpan data atau informasi geografis. Aplikasi SIG dapat digunakan untuk berbagai kepentingan selama data yang diolah memiliki referensi geografi, maksudnya data tersebut terdiri dari fenomena atau objek yang dapat disajikan dalam bentuk fisik serta memiliki lokasi keruangan. Salah satu aplikasi yang digunakan adalah Quantum GIS (QGIS). Data referensi geografi untuk keperluan GIS diperoleh dengan menggunakan metode penginderaan jauh (Remote Sensing). Penginderaan jauh adalah ilmu dan seni untuk memperoleh informasi tentang suatu obyek, daerah, atau fenomena melalui analisis data yang diperoleh dengan suatu alat tanpa kontak langsung dengan obyek, daerah, atau fenomena yang dikaji. Penginderaan jauh menggunakan citra optik dari satelit untuk melakukan pengukuran dan intepretasi data di lapangan. Citra optik yang biasa digunakan adalah citra Land Satellite. Salah satu kegunaan dari GIS itu sendiri yaitu kita akan lebih mudah dalam mengklasifikasi potensial untuk perencanaan jaringan jalan dari suatu wilayah. Dalam merencanakan jaringan jalan diperlukan data berubah kontur (elevasi) dari suatu wilayah yang bisa didapatkan dengan menggunakan citra satelit. Daerah yang ditinjau untuk penelitian adalah Kota Pare-Pare. Adapun tujuan penelitian yaitu 1. Menaganalisis bentuk demografi berbasis GIS di daerah Pare-Pare ; 2. Menganalisis karakteristik spasial Kota Pare-Pare dengan citra satelit. Dari hasil analisis ini menghasilkan karakteristik jalan, demografi, indeks vegetasi dan indeks hidrologi dari Kota Pare-Pare.\ud Kata kunci : Sistem Informasi Geografis (SIG), Penginderaan Jauh (Remote Sensing), Citra Land Satellite (Citra Landsat), Jaringan Jala

High Performance Asynchronous Bit-Level Parallel Interface for Board-to-Board Inter Processor Communication

In the Proc. of 2017 International Seminar on Intelligent Technology and Its Application (iSITIA 2017). Indexed by SCOPUSThis paper presents a bit-level parallel communication interface used for inter processor communication separated on different printed circuit boards. A high performance board-to-board communication interface is important in modern supercomputers and portable computers or gadgets with multiple screen displays. We propose a recalibrated transmitter and receiver soft IP cores to support asynchronous handshake communication interface. The valid signal can be delayed for a few cycle to guarantee the metastability of data signals. The tuning of the delay can be recalibrated and tested during pre-implementation step. The flexibility to tune a correct valid delay time, which\ud is set as minimum as possible as far as the data integrity can be guaranteed, enables the operation the communicating devices at its maximum performance. The proposed technique has been simulated using HDL-level simulation and has shown its expected\ud performance with four testing scenarios
