.Every company certainly has operating equipment that usually runs continuously and relies on electricity as an energy source whose distribution must be appropriate to be efficient in its use. Every company that has important activities that use electronic devices, of course, must have a power backup so that sudden power cuts do not occur, because if this happens frequently it will cause damage to electronic devices, one of which is using a UPS (Uninterruptible Power Supply). Uninterruptible Power Supply (UPS) is an electronic device capable of providing temporary backup power when the main power supply is cut off. This UPS is also an electronic device that can protect all types of electronic equipment that is vulnerable to current or voltage instability. The purpose of this study is to understand and know the working principle and how to maintain the use of UPS. The method used is the method of observation in the company to obtain research data. At PT. ASDP Indonesia Ferry uses two types of UPS which have different capacities, namely 0.8KVA and 3KVA to supply power to each electronic device that is used regularly. Of the two types of UPS, it can be used to back up electrical power when the main power source is suddenly cut off.
 
 

An expert system is an artificial intelligence program that combines a knowledge base with an inference system which is part of a high-level specialization software that seeks to duplicate the function of an expert in a field of expertise. This system was created with the aim of solving certain problems by imitating the work of experts from a field. Currently handling printer damage takes a long time to repair because there are many other printers that must be repaired. This expert system application uses the forward chaining method and literature studies into the Delphi 7 application which is useful for diagnosing damage and providing solutions to be carried out according to the symptoms given.

Kebutuhan akan konsumsi energi listrik sangat tinggi dan semua aktivitas manusia banyak yang menggunakan energi listrik. Listrik juga sangat dibutuhkan pada industri, karna seluruh alat hampir semua menggunakan listrik. Karna penggunaan listrik sangat besar pada PT. Cemindo Gemilang membangun unit WHRS (Waste Heats Recovery System) untuk menyuplai listrik. Dalam penelitian ini bertujuan untuk mengetahui bagaimana prinsip kerja serta proses kerja pada WHRS. Metode yang digunakan yaitu dengan observasi dan wawancara untuk mengetahui bagaimana proses pada WHRS tersebut. Hasil kesimpulan yaitu Waste Heats Recovery System ini merupakan pembangkit listrik yang menggunakan sisa panas atau flue gas sebagai pengganti batu bara untuk memanaskan air pada boiler.
