ABSTRACT

ZULFRIDEN SIREGAR: _{Distribution Vascular Bundles and Moisture Content}

on Oil Palm Trunk. Supervised by RUDI HARTONO and ERWINSYAH.

Oil palm trunk is the raw material testing vascular bundles and moisture content. The purpose of this study were to define the distribution pattern of vascular bundles and to define the distribution of moisture content at vertical and horizontal direction along the trunk Two palm trunks were cut into several section at 0,5 m, 2 m, 3,5 m, 5 m, 6,5 m, 8 m, and 9,5 m, and then cut into samples for determining the distribution of vascular bundles and moisture content vertically and horizontally.The result showed that vertically, the distribution of vascular bundles were decreased along the trunk height and it also decreased from outer to inner part of the trunk horizontally. Vertically, the distribution of moisture content were increased along the trunk height and it also increased from aouter to inner part of the trunk horizontally.Distribution vascular bundles and moisture content of oil palm trunk are different for both vertically as well as horizontally of the trunk height

Keywords: oil palm trunk, vascular bundles, moisture content.

ABSTRAK

ZULFRIDEN SIREGAR_{: Pola Penyebaran}_{Vascular Bundles}_{Terhadap Kadar} Air. Dibawah bimbingan RUDI HARTONO dan ERWINSYAH.

Batang kelapa sawit merupakan bahan baku pengujian vascular bundles

dan kadar air. Penelitian ini bertujuan untuk mengetahui pola penyebaran vascular bundles secara vertikal dan horizontal dan mengetahui distribusi kadar air secara vertikal dan horizontal. Batang kelapa sawit ditebang sebanyak dua batang pada ketinggian 0,5m, 2m, 3,5m, 5m, 6,5m, 8m, dan 9,5m, kemudian diamati jumlah

vascular bundles dan kadar air baik secara vertikal maupun horizontal. Hasil penelitian menunjukkan bahwasecara vertikal, semakin tinggi batang maka jumlah

vascular bundles yang ditemukan semakin berkurang, begitu juga secara horizontal, jumlah vascular bundles semakin berkurang dari bagian kulit/luar menuju pusat batang. Secara vertikal, semakin tinggi batang maka distribusi kadar air semakin besar, begitu juga secara horizontal, distribusi kadar air dari bagian kulit/luar menuju pusat semakin besar. Distribusi vascular bundles dan kadar air pada batang kelapa sawit berbeda secara vertikal dan horizontal

Kata kunci: batang kelapa sawit, vascular bundles, kadar air.
