Boiler Feed Water

One of the important elements produced from the factory support units is air products. Regional water balance (integration) is important to support factory operations. Raw water is treated in the unit section to produce demin water and further process into Boiler Feed Water (BWF) to produce 80 kg/cm2 pressurized steam in the boiler unit, to meet the specifications as demin water it is necessary to carry out several treatments to remove mineral ions (cations and anions) dissolved in the air. In the mixed bed polisher, there is a resin regeneration process to eliminate saturation of the resin which can no longer bind mineral ions. Regeneration or regent is carried out after the resin pile is saturated which is characterized by an increase in product productivity conductivity with the desired product conductivity target of <0.2 μS/cm at a temperature of 25℃. The purpose of this study was to work or perform a mixed bed polisher, especially during regeneration in the demineralization unit. This research was conducted by making a framework of thought and writing work. The writing stage contains data collection, data processing and data analysis-synthesis, as well as drawing conclusions. Based on this research, the results showed that there was a decrease in the performance of the mixed bed with a bed expansion gain of 80.7% and a resin height of 2.42 m. The number of chemicals used for regeneration is 1170.7 kg consisting of HCL and NaOH so that the flow rate of demin water required to dilute the regenerant is 7,126 m3/h.

Inovasi layanan drive-thru perpustakaan merupakan sebuah layanan yang diciptakan Dinas Perpustakaan dan Kearsipan Provinsi Jawa Timur. Inovasi layanan drive-thru ini berbentuk tempat / loket untuk melayani kebutuhan pemustaka tanpa harus turun dari kendaraan. Inovasi ini bertujuan untuk memudahkan pelayanan kepada pemustaka dengan harapan dapat meningkatkan budaya literasi.. Tujuan penelitian ini adalah untuk mendeskripsikan inovasi layanan drive-thru di Dinas Perpustakaan dan Kearsipan Provinsi Jawa Timur. Fokus penelitian ini adalah Kriteria Inovasi menurut PermenPANRB nomor 3 Tahun  2018 meliputi 5 variabel yang terdiri atas Kebaruan, Efektif , Bermanfaat , Dapat direplikasi, dan Berkelanjutan. Jenis penelitian ini adalah jenis deskriptif dengan pendekatan kualitatif. Untuk teknik pengumpulan data yang digunakan adalah wawancara,observasi, dan dokumentasi. Teknik analisis data yang digunakan adalah pengumpulan data, reduksi data, penyajian data, pemaparan dan penarikan kesimpulan. Untuk hasil penelitian menunjukkan inovasi layanan drive-thru memiliki kelebihan dan kekurangan. Pada kriteria kebaruan menunjukkan inovasi drive-thru merupakan suatu penemuan baru serta menawarkan cara baru dalam melayani pemustaka melalui loket. Untuk kriteria efektif tujuan dari diciptakannya drive-thru adalah untuk memudahkan pemustaka sudah memenuhi, tetapi untuk meningkatkan budaya literasi belum tercapai. Untuk kriteria bermanfaat sudah dapat memberikan manfaat bagi masyarakat dan bagi dinas yang menerapkannya. Pada dapat direplikasi inovasi ini dapat menjadi contoh/rujukan karena sudah ada beberapa instansi yang menduplikasinya, lalu kriteria terakhir keberlanjutan untuk kedepan inovasi ini akan tetap dipertahankan karena mendapat dukungan dari berbagai stakeholder. Saran yang dapat diberikan adalah lebih menggalakan sosialisasi agar drive-thru ini bisa lebih berkembang dan dimanfaatkan oleh lebih banyak orang.    Kata kunci : Inovasi Layanan, Drive Thru Perpustakaan, Budaya Literasi   The library's drive-thru service innovation is a service created by the Library and Archives Office of East Java Province. This drive-thru service innovation is in the form of a counter to serve the needs of visitors without having to get off the vehicle. This innovation aims to facilitate service to users in the hope that it can improve literacy culture. The purpose of this study is to describe the drive-thru service innovation in the Department of Library and Archives of East Java Province. The focus of this research is the Innovation Criteria according to the Regulation of the Minister of Administrative Reform and Bureaucratic Reform (PermenPANRB) number 3 of 2018 covering 5 variables consisting of novelty, effectiveness, benefit, transferbility, and sustainability. This type of research is a descriptive type with a qualitative approach. For data collection techniques used are interviews, observation, and documentation. The data analysis technique used was data collection, data reduction, data presentation, presentation and conclusion drawing. The research results show that drive-thru service innovation has advantages and disadvantages. The novelty criterion indicates that drive-thru innovation is a new invention and offers a new way of serving visitors through the counter. . For the effective criteria, the purpose of creating a drive-thru is to make it easier for users to fulfill it, but to improve literacy culture has not been achieved. For useful criteria, it can provide benefits for the community and for the agencies that implement them. If this innovation can be replicated, it can be used as an example / reference because there are already several agencies that duplicate it. Then the last criteria for sustainability for the future of this innovation will be maintained because it has the support of various stakeholders. Suggestions that can be given are to promote more socialization so that this drive-thru can be more developed and utilized by more people.

Time Varying Parameters

Stable control of water level of drum is of great importance for economic operation of power plant steam generator systems. In this paper, a linear model of the boiler unit with time varying parameters is used for simulation. Two transfer functions between drum water level (output variable) and feed-water and steam mass rates (input variables) are considered. Variation of model parameters may be arisen from disturbances affecting water level of drum, model uncertainties and parameter mismatch due to the variant operating conditions. To achieve a perfect tracking of the desired drum water level, two sliding mode controllers are designed separately. Results show that the designed controllers result in bounded values of control signals, satisfying the actuators constraints.
