Produktivitas Sadapan Pinus Pascapemulihan di KPH Bogor Divisi Regional Jawa Barat dan Banten Perum Perhutani
Abstract
Permintaan produksi getah pinus terus meningkat, namun produksi getah
pinus menurun. Salah satu penyebabnya yaitu karena tegakan pinus mengalami
jenuh sadap (belum saatnya untuk ditebang namun bidang sadap sudah habis).
Produktivitas getah pinus pascapemulihan yaitu sadapan pinus yang dilakukan pada
bidang sadap yang telah mengalami penutupan luka belum diketahui. Penelitian ini
bertujuan untuk mengukur persentase pemulihan bidang sadapan pinus metode
quarre dan menganalisis produktivitas sadapan pinus pascapemulihan pada kedua
kelas umur pohon. Rancangan percobaan yang digunakan adalah rancangan acak
kelompok terdiri dari dua perlakuan yaitu sadapan pascapemulihan dan kontrol
sedangkan kelompok yaitu tegakan pinus kelas umur (KU) IV dan IX. Hasil
penelitian menunjukkan rata-rata pemulihan bidang sadapan pinus KU IX lebih
tinggi dibandingkan KU IV. Rata-rata produktivitas getah pinus (g/pohon/hari)
perlakuan pascapemulihan lebih rendah dibandingkan kontrol pada kedua kelas
umur yaitu KU IV dan KU IX perlakuan pascapemulihan berturut-turut 8,11
g/pohon/hari dan 9,15 g/pohon/hari sedangkan perlakuan kontrol berturut-turut
11,42 g/pohon/hari dan 10,59 g/pohon/hari. Perlakuan (pascapemulihan dan
kontrol) sadapan getah pinus menghasilkan produktivitas yang berbeda sedangkan
kelas umur menghasilkan produktivitas yang sama. The demand for pine resin continues to increase along with the declining of
pine resin production. One of the reasons is because the pine trees have become
saturated with tapping (it is not proper yet to cut down, but the tapping fields have
run out). Post-recovery pine resin productivity, namely pine tapping in a tapping
area that had undergone closure of the tapping wound not yet known. This study
aimed to measure the percentage of pine tapping field recovery using the quarre
method and to analyze the productivity of post-recovery pine resin in both age
classes of trees. The experimental design used a randomized block design
consisting of two treatments, namely post-recovery and control, while the group
consisted of pine stands of age class IV and IX. The results showed that the average
recovery of the pine tapping field in age class IX was higher than age class IV. The
average productivity of pine resin (g/tree/day) in post-recovery treatment was lower
than the control in both age classes, namely age class IV and IX in post-recovery
treatment, respectively 8.11 g/tree/day and 9.15 g/tree/day while the control
treatments were 11.42 g/tree/day and 10.59 g/tree/day, respectively. Treatments
(post-recovery and control) on tapped pine resin had a different productivity, while
the groups (age class) had the same productivity.
