Abstract

Untai Fasilitas Simulasi Sistem Pendingin Pasif-03 Nanobubbles Transparent (FASSP-03 NT) merupakan salah satu fasilitas penelitian untuk mempelajari sistem pendinginan pasif.  Heating Tank Section (HTS) merupakan salah satu komponen pada untai FASSIP-03 NT yang berfungsi untuk menaikkan temperatur fluida kerja, dan sebagai sumber kalor HTS menggunakan pemanas listrik tipe immersion. Penelitian dengan kegiatan komisioning pemanas listrik bertujuan untuk mengetahui kinerja dan karakterisasi pemanas listrik tipe immersion sebagai sumber kalor, sehingga saat eksperimen berlangsung dapat berjalan sesuai yang direncanakan pada matrik penelitian. Tahapan yang dilakukan adalah, melakukan eksperimen untuk mengetahui temperatur pada beberapa titik di untai FASSIP-03 NT. Pengambilan data dilakukan secara transien dan steady state terekam dan tersimpan pada komputer Data Akuisisi Sistem (DAS). Data kelistrikan pada pemanas listrik meliputi tegangan listrik dan arus listrik dicuplik dan dicatat secara manual pada interval tertentu. Hasil perhitungan diperoleh energi listrik yang digunakan sebesar 50.622.441,000 Joule. Energi listrik tersebut digunakan untuk menaikkan temperatur air sekunder HTS hingga mencapai temperatur 85 ℃ dalam waktu 7143 detik. Energi kalor yang dihasilkan oleh pemanas listrik sebesar 22.223.674,562 Joule dan efisiensinya sebesar 43,901 %.

Abstract

Temperature stability is a crucial factor in industries such as chemicals, pharmaceuticals, and food processing, where fluctuations can damage product quality and increase energy consumption. This study aims to optimize heater power control using an adaptive proportional integral derivative (PID) control system to maintain temperature stability under steady-state conditions. The method involves applying adaptive PID control to a stirred heating tank using LabVIEW software with a national instruments controller module and a single-phase SCR to regulate heater power and adjust control parameters in real time. The results indicate that the system operates more effectively under stable conditions, with faster response times and a lower overshoot of less than 0.12%. However, under disturbed conditions, such as water drainage and replacement, the system requires more time to adjust the temperature and experiences increased energy consumption and heat loss. Despite this, the system still achieves an energy efficiency improvement, with efficiency values ranging from 77.66% to 80.03%. The implementation of adaptive PID control demonstrates significant potential in enhancing system accuracy and response to temperature changes, contributing to the development of more efficient industrial control technologies.

Abstract

In today's digital era, effective inventory management is essential to ensure smooth business operations and meet customer demands. The system is designed to facilitate stock monitoring, real-time inventory updates, allowing store owners to manage inventory more efficiently. This study aims to design an Android-based inventory management information system for Toko Bintang Jaya in Simpang Hilir District. The methods used in this study include object-oriented analysis and design techniques, with system modeling using Unified Modeling Language (UML). The system analysis process involves mapping user needs, designing workflow diagrams, and identifying features that will be implemented in the system. The application was developed using android studio as the main text editor, with the Java programming language. For database management, use Firebase Realtime Database, which allows the system to store and access data in real-time. In addition, this system also uses the concept of NoSQL for more flexible and efficient data management in Android-based applications. The results of this study are expected to increase efficiency and accuracy in inventory management, minimize stock recording errors, and improve the quality of service to customers. With the implementation of this system, inventory management will become faster and more reliable, thereby reducing the risk of excess or shortage of stock. Overall, this research contributes to the development of information technology in the retail sector and supports businesses in optimizing inventory management processes.
