#### Abstract

Abstract– In electrical engineering, there are several power terms; active power, reactive power, instantaneous active power, instantaneous active power, instantaneous power, apparent power and complex power. Even though are used in daily activity, electrical practitioners are facing difficulty to explain those terms practically. This paper tries to solve those difficulty by interpret those term in practical way. Firstly, each power term are defined theoretically. Then those terms are presented mathematically. Next, power in single phase sinusoidal electric network is analyzed. Theoretical definition result is connected with power analysis result. Computer simulations are held to strengthen interpretation result. Considering the width of discussion area, this paper only covers most general application, that is single phase sinusoidal network.

Keywords : practical interpretation, analysis, power terms, electrical network, single phase sinusoidal.

Intisari – Dalam dunia teknik elektro, dikenal istilah-istilah daya, yaitu daya aktif, daya reaktif, daya aktif sesaat, daya reaktif sesaat, daya sesaat, daya semu dan daya kompleks. Walaupun lazim digunakan sehari-hari, para praktisi teknik elektro kerapkali kesulitan untuk menjelaskan secara praktis pengertian dari masing-masing istilah tersebut. Tulisan ini mencoba mengatasi kesulitan tersebut dengan menginterpretasikan secara praktis istilah-istilah daya tersebut. Interpretasi diawali dengan melakukan definisi dari istilah-istilah daya tersebut. Kemudian dilakukan penjabaran secara teoritis melalui persamaan matematis. Langkah berikutnya adalah melakukan analisis daya pada rangkaian listrik satu fase sinusoidal. Hasil penjabaran teoritis dihubungkan dengan hasil analisis daya. Simulasi dengan komputer juga dilakukan untuk memperkuat interpretasi praktis. Mengingat luasnya cakupan, diskusi akan dibatasi untuk penerapan yang paling umum, yaitu pada rangkaian listrik satu fase sinusoidal.

Kata kunci : interpretasi praktis, analisis, istilah daya, rangkaian listrik, satu fase sinusoidal.
