Waste Energy

This work covers waste energy utilization of the combined power cycle by using it in the candle raw material (paraffin) melting process and an economic study for this process. After a partial utilization of the burned fuel energy in a real bottoming steam power generation, the exhaust gas contains 0.033 of the initially burned energy. This tail energy with about 128 ºC is partly driven in the heat exchanger of the paraffin melting system. Ansys-Fluent Software was used to study the paraffin wax melting process by using a layered system that utilizes an increased interface area between the heat transfer fluid (HTF) and the phase change material (PCM) to improve the paraffin melting process. The results indicate that using 47.35 kg/s, which is 5% of the entire exhaust gas (881.33 kg/s) from the exit of the combined power cycle, would be enough for producing 1100 tons per month, which corresponds to the production quantity by real candle's factories. Also, 63% of the LPG cost will be saved, and the payback period of the melting system is 2.4 years. Moreover, as the exhaust gas temperature increases, the consumed power and the payback period will decrease.

Dalam mendukung program pemerintah yaitu Sistem Pemerintahan Berbasis Elektronik (SPBE), Dinas Pariwisata dan Kebudayaan Kabupaten Bandung Barat (Disparbud KBB) khususnya pada fungsi Kepegawaian Umum dan Bina Budaya diupayakan dapat menyelaraskan antara layanan bisnis dan layanan teknologi informasi dalam melakukan perubahan dari segi layanan internal maupun publik dalam mengembangkan potensi kebudayaan dan pariwisata untuk meningkatkan perekonomian masyarakat Kabupaten Bandung Barat. Enterprise Architecture (EA) menjadi jawaban sebagai pengembangan rancangan dokumentasi blueprint TI. Perancangan EA pada penelitian ini menggunakan kerangka kerja TOGAF ADM untuk memenuhi kebutuhan pengembangan sistem melalui Phase C: Information System Architecture (Data Architecture & Application Architecture). Metode analisis dokumen, wawancara dan observasi dilakukan dalam menunjang pencaharian kebutuhan informasi organisasi selama pengembangan EA. Adapun hasil yang didapatkan berupa solusi integrase proses data dan aplikasi melalui teknologi Government Service Bus (GSB).

Abstract Comprehensive in situ (designed-in) diagnostic capabilities have been incorporated into digital microelectronic systems for years, yet similar capabilities are not commonly incorporated into the design of analog microelectronics. And as feature sizes shrink and back end interconnect metallization becomes more complex, the need for effective diagnostics for analog circuits becomes ever more critical. This paper presents concepts for incorporating in situ diagnostic capability into analog circuit designs. Aspects of analog diagnostic system architecture are discussed as well as nodal measurement scenarios for common signal types. As microelectronic feature sizes continue to shrink, diagnostic capabilities such as those presented here will become essential to the process of fault localization in analog circuits.
