    Abstract
    The use of non-linear loads generated by industrial machinery can result in current harmonics according to the standard IEEE 519 - 1992 This thesis discusses the use of single tuned passive filter and the matrix filter in reducing harmonics and comparing the results of the reduction of the both filter. Modeling system being simulated using simulation matlab / Simulink produces a total harmonic distortion (THD) of 15.55%, can be reduced to 4.77% using a single passive filter tuned and 3.06% using a filter matrix. So both filter generates harmonics which conform to the IEEE 519 - 1992. From the simulation results shown also that the single tuned passive filter capable of reducing harmonic current target of 82.23% in ordo harmonics want to reduce harmonics are reduced and other ordo between 7% to 8%. While using filter matrix able to reduce harmonics ordo to expect the target of 97.86% and other harmonic ordo can reduce between 50% to 70%.
     
    Penggunaan beban non linier yang ditimbulkan oleh mesin-mesin industri dapat mengakibatkan harmonisa arus yang tidak sesuai dengan standar IEEE 519 – 1992. Tesis ini membahas tentang penggunaan filter pasif single tuned dan filter matrix dalam mereduksi harmonisa dan membandingkan hasil reduksi dari kedua filter tersebut. Permodelan sistem yang ditinjau menggunakan simulasi matlab/simulink menghasilkan total harmonic distortion (THD) sebesar 15,55%, dapat direduksi menjadi 4,77% menggunakan filter pasif single tuned dan 3,06% menggunakan filter matrix. Sehingga dengan kedua filter tersebut menghasilkan harmonisa yang sesuai dengan standar IEEE 519 – 1992. Dari hasil simulasi terlihat juga bahwa filter pasif single tuned mampu mereduksi harmonisa arus 82,23% pada target ordo harmonisa yang ingin direduksi dan mereduksi harmonisa ordo lainnya antara 7% sampai 8%. Sedangkan dengan menggunakan filter matrix mampu mereduksi harmonisa pada target ordo yang diinginkan sebesar 97,86% dan mampu mereduksi ordo harmonisa lainnya antara 50% sampai 70%.
