Abstract

Studi tentang manajemen pendidikan Seni Rupa dilakukan untuk memperoleh model manajemen pendidikan seni yang efektif. Sejak lama telah terjadi fenomena kegelisahan di dunia pendidikan tentang efektifitas proses pendidikan seni yang terkesan masih belum produktif dan efisien . Hal ini dapat dilihat pada proses-proses pendidikan di banyak sekolah, misalnya tentang penataan kurikulum, penyusunan perangkat pembelajaran, kesediaan tenaga guru yang masih banyak bukan dari lulusan yang sesui bidang setudi, materi dan peralatan yang belum memadai, serta sistem menejemen yang masih kurang efektif. Pendidikan seni yang efektif dibutuhkan inovasi manajemen yang baik pula. Untuk menciptakan sebuah manajemen pendidikan seni yang efektif dan baik sangat penting dalam melibatkan pakar atau ahli dibidangnya. Hal tersebut tentu niscaya akan mampu membawa hasil produk manajemen seni yang memiliki karakteristik dan berdampak pada implementasi yang sesuai dengan kebutuhan proses pembelajaran yang efektif. Manajemen dalam sebuah pendidikan seni merupakan kebutuhan untuk memudahkan pencapaian tujuan pendidikannya, serta dibutuhkan dalam mengelola segela sumber daya yang ada, misalnya seperti sarana prasarana, waktu, SDM, dan metode yang inovatif, efektif dan efisien. Berdasarkan hal-hal tersebut sangat penting melibatkan banyak pihak kususnya para ahli dibidang manajemen pendidikan seni yang akan dapat menghasilkan formulasi manajemen yang efektif dalam menjalankan kurikulum, sarana prasarana, dan tenaga pengajar yang sesuai dengan ciri khas pendidikan seni yang terprogram dalam fungsi manajemen pendidikan seperti : 1) perencanaan, 2) pengorganisasian, 3) pelaksanaan dan 4) evaluasi.
