Jaringan jalan hutan berperan penting dalam mendukung kegiatan pengelolaan dan pemanenan hasil hutan. Penelitian ini bertujuan untuk mengevaluasi karakteristik jaringan jalan, kondisi fisik jalan, bangunan air, dan intensitas penggunaan jalan pada hutan produksi kayu jati di Petak 142 dan 143 RPH Karangduwet, KPH Yogyakarta. Penelitian dilakukan menggunakan metode observasi lapangan dengan bantuan Sistem Informasi Geografis (SIG), pemasangan kamera trap, dan wawancara dengan pihak pengelola. Parameter yang dianalisis meliputi kerapatan jalan (Road density), jarak antar jalan (Road Spacing), jarak sarad, faktor koreksi jaringan jalan, pembukaan wilayah hutan, kondisi jalan, bangunan air, dan lalu lintas harian rata-rata (LHR).
Hasil penelitian menunjukkan bahwa panjang total jaringan jalan mencapai 9.949,57 m dengan nilai Road density sebesar 55,55 m/ha dan Road Spacing sebesar 180,03 m. Nilai JSRt, JSRp, dan JSRr berturut-turut sebesar 45,01 m, 101,27 m, dan 126,62 m, sedangkan persentase pembukaan wilayah hutan sebesar 44,44%. Kondisi jalan didominasi oleh perkerasan tanah dengan kerusakan berupa rutting, cracks, potholes, loss of surfacing, penurunan badan jalan, dan pertumbuhan vegetasi. Bangunan air juga ditemukan dalam kondisi yang tidak memadai. Intensitas penggunaan jalan tergolong rendah hingga sedang, dengan rata-rata LHR sebesar 2,37 kendaraan/jam, dan didominasi oleh sepeda motor serta pejalan kaki. Hasil penelitian menunjukkan bahwa jaringan jalan di RPH Karangduwet memiliki kerapatan jalan yang tinggi, namun kualitas infrastruktur dan tingkat pembukaan wilayah hutan masih perlu ditingkatkan melalui pemeliharaan jalan dan rehabilitasi bangunan air secara berkala.

Forest roads play an important role in supporting forest management and timber harvesting activities. This study aimed to evaluate the characteristics of the forest road network, road conditions, water drainage structures, and road use intensity in the teak production forest of Compartments 142 and 143, Karangduwet Forest Range (RPH), Yogyakarta Forest Management Unit (KPH). The study was conducted using field observations with Geographic Information System (GIS), camera trap installation, and interviews. The evaluated parameters included Road density (RD), Road Spacing (RS), skidding distance, road network correction factors, forest area opening percentage, road conditions, water drainage structures, and Average Daily Traffic (ADT).
The results showed that the total forest road length was 9,949.57 m, with a Road density value of 55.55 m/ha and a Road Spacing value of 180,03 m. The average theoretical, shortest, and actual skidding distances were 45.01 m, 101.27 m, and 126,62 m, respectively, while the forest area opening percentage was 44.44%. Road conditions were dominated by earth-surfaced roads, with damage including rutting, cracks, potholes, loss of surfacing, road surface settlement, and vegetation encroachment. Water drainage structures were found to be inadequate. Road use intensity was classified as low to moderate, with an average ADT of 2.37 vehicles/hour, predominantly consisting of motorcycles and pedestrians. The study concluded that the forest road network in Karangduwet RPH has a high Road density; however, its infrastructure quality and forest area opening level still require improvement through regular road maintenance and rehabilitation of water drainage structures.
