"Penelitian yang dilakukan untuk tugas akhir ini menggunakan miniatur Pembangkit Listrik Tenaga Uap (PLTU) ini diproduksi oleh SNM (Shin Nippon Machinery) dengan TIPE 100-SCR. PLTU ini mampu menghasilkan daya listrik sebesar 450 Watt dengan kapasitas uap maksimum 130 kg/jam. Penelitian ini dilakukan bersama dengan Wawan Mardiyanto dengan masing¬masing menganalisa karakteristik PLTU pada titik pengaturan temperatur superheater yang ditentukan yaitu pada 205oC dan 215°C. Tujuan penulisan tugas akhir ini adalah untuk mengetahui karakteristik dan performance PLTU 450 Watt dengan kondisi pengaturan temperatur superheater 205°C. Pengujian dilakukan dengan cara mengoperasikan PLTU 450 pada pengaturan temperature superheater 205°C dengan variasi pembebanan 100 Watt, 200 Watt, 300 Watt dan 450 Watt. Dari data hasil pengujian yang diperoleh kemudian di plot pada diagram h-s, T-s dan p-h untuk mengetahui karakteristik PLTU. Setelah dilakukan perhitungan pada beban puncak (450 W), diperoleh effisiensi thermal yang kecil yaitu sebesar 3,88%. Kenaikan temperatur pada superheater tidak sebanding dengan kenaikan effisiensi thermal system. Hal ini dapat dilihat pada diagram h-s dan T-s dan p-h dimana terjadi losses pada saat uap dialirkan dari boiler menuju superheater sebesar 0,4 kJ/kg dan dari superheater menuju turbin sebesar 78 kJ/kg.

ABSTRACTEscalation of electricity demand which cannot be avoided anymore has made electricity a primary need for human race. This climbing demand need to be balanced out with a sufficient power available on the system. The availability of extra generation capacity is required in order to maintaining the reliability of generation system for so called reserve margin. For ensuring the demand get enough power supplied, the generation planning system is needed and for it to provide the optimum option for system it require a calculation regarding each generation technologies with screening curve method. This calculation modelling the generation planning system in Jawa Bali region. On this study the main focus for the calculation is thermal generation which represented by three generation technologies Coal Fired Power Plant, Gas Turbine Power Plant, and Combined Cycle Power Plant . Therefore, from this study we can obtain that Coal Fired Power Plant is an optimum option for base load as well as economically for capacity between 50 . For intermediate load Combine Cycle Power Plant provide cheaper source of energy for capacity between 12 50 , and lastly for peak load Gas Turbine Power Plant provide the optimum option for capacity between 0 12 . The results for generation system planning based on screening curve method until the end of 2016 is 32,566 MW for generation capacity compared to the existing generation and system planning based on PT. PLN Persero which is 36,720 MW. The generation system planning until 2020 also shows a difference based on calculation which is 45,426 MW and the existing generation capacity reach 51,462 MW. This shows that Jawa Bali region has more generation existing meaning that the system is reliable. On the other hand, the reliability comes with higher investment costs making the costs needed for the system also increased. It is believed that to ensure reliability of the generating system there will be higher costs to pay. "

"Sistem perpipaan dalam dunia industri, seperti pada refinery plant, steam power plant, chemical plant, dan lain-lain berfungsi mengalirkan fluida dari suatu peralatan ke peralatan lainnya. Peralatan yang terhubung dengan sistem perpipaan akan mempengaruhi beban yang diterima dan tingkat fleksibilitas sistem perpipaan. Sistem perpipaan harus dapat menahan beban yang diterimanya dan memiliki fleksibilitas yang baik sehingga tidak terjadi tegangan yang berlebihan dan kegagalan lainnya yang dapat mengganggu seluruh proses. Oleh karena itu, dilakukan analisis fleksibilitas dan tegangan pada sistem perpipaan secara sederhana atau dengan menggunakan software komputer seperti caesar II sesuai kebutuhan. Analisis fleksibilitas dan tegangan juga digunakan sebagai acuan penentuan jenis dan peletakan support pipa dengan juga mempertimbangkan nilai ekonomis dan tingkat keamanan sistem perpipaan sesuai code ASME B31.3 dan standar yang digunakan. Review yang dilakukan terhadap desain condensate piping system pada plant NGF 2 menunjukkan adanya kelebihan beban dan pergerakan yang terjadi pada beberapa bagian pipa. Perubahan desain support pipa yang bermasalah dilakukan agar sistem perpipaan berada dalam batas aman.

Piping system in the industry, such as refinery plant, steam power plant, chemical plant, and other drains fluid from an equipment to other equipment. Equipment connected to the piping system will affect load received and the level of flexibility of the piping system. Piping system must be able to support the weight it receives and has good flexibility so that no excessive stress and other failures that can disrupt the entire process. Therefore, simple flexibility and stress analysis on a piping system or by using computer software such as Caesar II as needed.

Flexibility and stress analysis is also used as a reference for determining the type and pipe laying support primarily to also consider the economic value and the level of security appropriate piping code ASME B31.3 and standards used. Review conducted on the design of condensate piping system on NGF 2 plant shows excessive movement and overloaded occurring in some parts of the pipe. Pipe support design changes done to the piping system problems are within safe limits."
