Abstract

ABSTRACT   Bambu tali (Gigantochloa apus Kurz.) known as bambu species that used many for handicraft materials. But their clump existence often damage without tending and many cutting remainder  the research of repairing technique of clump to improve the productivity of culms have been done in forest research station Balai Penelitian Kehutanan Ciamis for 2 years from 2009 to 2010. The research were arranged according to RCBD (Random completely block design) consist of three treatments that are : A. Clump repaired total, all cutting remainder were removed, B. Clump repaired apart, half of cutting remainder were removed,  C. Clump without repaired, as control. Every treatment consist of  seven  replications and the data collection includes of the amount of culm/clump, clump circumference, clump density, culm high and culm diameter. Data collecting done in the intial and one year after treatment. All data were analyzed by the  analysis of variance. Result of research showed that clump repaired total (A) can improve the amount of culm/clump of  116,2% bigger compared to clump repaired apart (B) which only 67,3% and or again clump without repairing (C)  which 50,3%. Beside that, clump reapiring total (A) can improve the culm height of 107,3% bigger compared to clump repaired (B) which of 101,6% or and the clump without repaired (C) which only 100,0%. Meanwhile though don't significant but clump repaired total (A) tend to to improve the culm diameter compared to the clump repaired apart (B) and or clump without repaired (C). Key words : bambu tali, Gigantochloa apus Kurz., clump damage, clump repairing, improve, culm productivity.

Abstract

ABSTRAK   Bambu petung (Dendrocalamus asper Back.) secara alami akan tumbuh baik pada tempat-tempat yang berada pada ketinggian >300 m dpl. Namun di desa Majasari, kecamatan Cibogo, kabupaten Subang , bambu petung ditanam di dataran rendah (<90 m dpl). Penelitian karakteristik pertumbuhan tanaman bambu petung di dataran rendah telah dilakukan. Hasil penelitian menunjukan struktur kelompok umur batang bambu petung di desa Majasari terdiri dari 81,9%  tegakan rumpun berstruktur 3 kelompok umur batang, 17,8% tegakan rumpun  berstruktur 2 kelompok umur batang dan  0,3% tegakan rumpun  yang berstruktur hanya 1 kelompok umur batang.  Komposisi kelompok umur batang tersebut relatif berimbang antara batang umur 1, 2 dan 3 tahun masing-masing adalah 37,0%, 32,6% dan 30,4%. Karakteristik tegakan rumpun bambu petung dicirikan dengan rata-rata jumlah batang/rumpun ialah 30,2 batang/rumpun, keliling rumpunnya 8,8 m dan kerapatan rumpunnya 3,2 batang/meter. Karakteristik tegakan batang tergolong berukuran kecil dicirikan dengan rata-rata diameter batang 11,5 cm, tinggi batang 15,8 meter dengan tinggi bebas cabang 6,9 meter, berat batang segar 39,6 kg dan tebal dinding batang 3,9 cm. Angka permudaan tergolong cukup besar yaitu 81,9% sehingga potensi produktivitasnya juga besar.   Kata kunci : karakteristik, bambu petung (Dendrocalamus asper Back.), dataran rendah
