Abstrak: Perhutanan Sosial adalah sistem pengelolaan hutan lestari yang dilaksanakan oleh masyarakat setempat untuk meningkatkan kesejahteraan masyarakat, keseimbangan lingkungan, dan dinamika sosial budaya. Program ini juga dikaitkan dengan upaya pencapaian Tujuan Pembangunan Berkelanjutan (Sustainable Development Goals/SDGs) sebagai bentuk kontribusi Indonesia sebagai warga global. Penelitian ini bertujuan untuk mengevaluasi program Perhutanan Sosial terhadap tercapainya tiga tujuan utama yaitu secara sosial, ekologi dan ekonomi. Pengambilan data dilakukan melalui wawancara mendalam secara online dan studi dokumen. Penelitian dilakukan pada Perhutanan Sosial pola Hutan Kemasyarakatan (HKm) di kawasan Hutan Lindung Kulon Progo. Hasil penelitian menunjukkan 1) dengan adanya program Perhutanan Sosial, masyarakat bisa guyub dan merencanakan tata kelola hutannya karena adanya organisasi dan aturan main yang inovatif; 2) dampak Perhutanan Sosial secara ekologi mendorong masyarakat untuk menjadikan kawasan HKm Kalibiru tetap tumbuh dan lestari dengan melakukan konservasi, perlindungan dan pengamanan hutan; 3) dampak program Perhutanan Sosial secara ekonomi meningkatkan pendapatan ekonomi masyarakat dan menyerap banyak tenaga kerja. Setelah mengikuti Perhutanan Sosial, pendapatan masyarakat di HKm Kalibiru meningkat sekitar 85%. Bila pada era sebelum Perhutanan Sosial, pendapatan petani sebesar Rp. 800.000 per bulan; maka pada era dengan Perhutanan Sosial pendapatan meningkat menjadi Rp 2.000.000 per bulan., Social Forestry is sustainable forest management system implemented by local communities to increase community welfare, environmental balance and social cultural dynamics.
