Abstrak-Makalah ini membahas tentang perancangan sistem pemantauan pengendali suhu pada sistem stirred tank heater yang mempunyai peranan penting dalam proses industri. Pemantauan sistem kendali suhu pada stirred tank heater ini dirancang menggunakan Supervisory Control and Data Acquisition (SCADA) yang berfungsi memantau jalannya sistem. Sedangkan aktuator yang akan dikendalikan adalah posisi bukaan burner sehingga besarnya panas akan dapat diatur guna memenuhi set-point yang telah ditentukan. Pengendali suhu yang juga digunakan sebagai Remote Terminal Unit (RTU) adalah Programmable Logic Controller (PLC). Hasil pengujian yang tertera pada tampilan sistem SCADA termasuk dalam kategori baik, dimana persentase error rata-rata untuk data pengujian set-point adalah 0.76687% serta persentase error untuk data suhu adalah 0.082%. Kata kunci: SCADA, stirred tank heater, bukaan burner, pemantauan, RTUAbstract-This paper discusses design of a suhue control monitoring system in stirred tank heater system that has an important function in industrial processes. Monitoring of suhue control system in stirred tank heater is designed using Supervisory Control and Data Acquisition (SCADA) that control function of industrial processes. While the actuator to be controlled is the position of burner openings, so that the heat can be adjusted to meet a predetermined set-point. The suhue controller that is also used as a Remote Terminal Unit (RTU) is Programmable Logic Controller (PLC). The testing result showed on SCADA system was quite good, where the average percentage of deviation for testing of set-point data was 0.76687%, and the percentage of deviation for testing of suhue data was 0.082%.
Business is a trade undertaken by group organized in order to make a profit by producing and selling goods and services to meet the community needs. Business is not only seen from the clothing business but other like food or beverage business that encompasses the entire world. In this modern business era, more and more emerging SMEs make competition tighter. By examining the influence of product quality, price, it is and service quality variables that expected in this research strategy output can increase consumer satisfaction of Dorayaki products at CV Abe Seika. The survey method with a quantitative approach was used in this study.The questionnaire results were processed using SEM (structural equation modeling). From the study results known that produced a strategy of product quality variables with Dorayaki product quality indicators. It is expected to increase customer satisfaction from implementing results the right strategy. Therapy needs further research on success of this consumer satisfaction assessment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
