Abstract

Abstrak Provinsi Papua merupakan salah satu provinsi terkaya di Indonesia dengan luas wilayahnya tiga kali lebih luas wilayah Pulau Jawa, namun kekayaan alam yang begitu besar belum dapat diolah karena belum adanya jaringan jalan yang memadai untuk menghubungkan wilayah-wilayah sentra produksi sehingga masih banyak wilayah-wilayah di Papua yang masi terisolasi dan kurang berkembang. Sama halnya dengan kondisi kelistrikan di Provinsi Papua, berdasarkan Statistik Ketenagalistrikan Tahun 2018 diketahui bahwa rasio elektrifikasi di Provinsi Papua sebesar 61,42 % yang merupakan terendah kedua dari rasio elektrifikasi seluruh Indonesia. Permasalahan di atas hanya mungkin dapat diatasi dengan melakukan diversifikasi sumber energi baik menyangkut jenis maupun jumlahnya melalui pemanfaatan berbagai sumber energi alternative khususnya sumber energi terbarukan (renewable energy). Karena sistem OTEC dipasang di daerah pantai atau lepas pantai maka potensi OTEC di Provinsi Papua terdapat di daerah-daerah di sepanjang perairan Provinsi Papua yang memiliki kedalaman laut ± 1000 m. Efisiensi maksimum sistem OTEC di perairan Nabire sebesar 0,76 sedangkan di perairan Biak, Bonggo, dan Jayapura mempunyai efisiensi maksimum yang hampir sama yaitu 0,84.Kata Kunci: OTEC, konversi energi.

Abstract

DC motors are a popular topic because they are widely applied in various electronic equipment. So, this requires a control that is fast and reliable. The development of optimized control methods is growing rapidly with the discovery of several new methods. Marine predator algorithm (MPA) is an optimization method based on marine life between living things. This article discusses the application of the MPA method for optimizing fractional order PID (FOPID) control on DC motors. The implementation of the FOPID controller is also difficult because the fractional calculus operators of the FOPID controller cannot be directly implemented in numerical calculations. The method proposed in this article is the FOPID-MPA method. To get a performance test of the proposed method, this study uses several comparison methods, namely the seagull optimization algorithm (ASO), chimp optimization algorithm (ChOA), and sine tree seed algorithm (STSA). This study also uses a variation of the reference speed to get the performance of the proposed method. From the experiment it is known that the FOPID-MPA method gives the best performance. The FOPID-MPA method has an overshoot value of 4.34% compared to the PID-MPA method in case study 1 and has an integrated of time-weighted-squared-error (ITSE) value of 7.44% better than the PID-MPA method in case study 2.
