Penilaian Jaringan Jalan Angkutan Kayu Bulat pada Medan Datar di Hutan Rakyat Wonosobo Jawa Tengah

Abstract

Ketersediaan pasokan kayu bulat dari hutan produksi alam di luar Jawa dan Perhutani di pulau Jawa semakin menurun. Salah satu sumber pasokan kayu bulat yang potensial adalah hutan rakyat. Kayu bulat hasil penebangan di hutan rakyat Wonosobo diangkut melalui jaringan jalan angkutan kayu bulat yang sudah tersedia. Penelitian ini bertujuan menilai jaringan jalan angkutan kayu bulat di medan datar pada petak penebangan hutan rakyat di Wonosobo, Jawa Tengah. Penelitian ini dilakukan di dua petak tebang. Parameter penilai PWH yang digunakan meliputi kerapatan jalan (WD), spasi jalan (WA), jarak sarad rata-rata (RE), faktor koreksi jaringan jalan (Vcoor), dan persen PWH (E). Hasil penelitian menunjukan bahwa jaringan jalan angkutan pada petak tebang ke-1 memiliki nilai Vcoor sebesar 1,17 dan persen PWH sebesar 85,24%, pada petak tebang ke-2 memiliki nilai Vcoor sebesar 1,02 dan persen PWH sebesar 98,34%. Hasil penelitian menunjukkan bahwa jaringan jalan angkutan di lokasi penelitian mampu melayani seluruh areal hutan rakyat yang dipanen.

The availability of roundwood supplies from natural production forests outside Java and Perhutani on the island of Java is declining. One potential source of roundwood supply is private forests. Roundwood harvested from private forests in Wonosobo is transported via an existing road network. This study aims to assess the roundwood transportation road network in private forests in the flat terrain in Wonosobo, Central Java. The study was conducted in two cutting blocks. The forest opening’s parameters were used include road density (WD), road spacing (WA), average road distance (RE), road network correction factor (Vcoor), and PWH percentage (E). The results showed that the road network in the first cutting block had a Vcoor value of 1.17 and a PWH percentage of 85.24%, while the second cutting block had a Vcoor value of 1.02 and a PWH percentage of 98.34%. The results indicate that the road network at the study site can serve the entire area of the private forest being harvested.
