Abstract

The purpose of this study was to determine the variation of the stem anatomical structure (i.e. cortex: sclerenchyma, phloem; xylem: trachea, rays, interxylary phloem and wood parenchyma; and pith) of Gyrinops (Thymelaeaceae) in Sulawesi. The method of this research was descriptive exploration. Stem agarwood sample came from several regions areas of Sulawesi which were collected by Agarwood Research Center Laboratory, Faculty of Mathematics and Natural Sciences, University of Mataram. The slide methods were used fresh slides. The results of this research showed there were 1 species of Gyrinops decipiens  and 3 species of Gyrinops sp., with various anatomical characters in G. decipiens  and Gyrinops sp. in terms of the position, diameter and percentage of pith thickness; cortical sclerenchyma pattern and arrangement of wood parenchyma. There were also variations in cortical thickness; diameter, frequency and arrangement of trachea; frequency of rays; diameter, and interxylary phloem frequency; pith diameter; and the position of Ca-Oxalate in Gyrinops sp. 3 with Gyrinops sp. 1 and 2, while Gyrinops sp. 2 with Gyrinops sp. 1 there were found 5 variations such as the diameter, frequency and arrangement of trachea; arrangement of rays and interxylary phloem length.

Abstract

Harga pasar gaharu yang tinggi sangat berpengaruh pada pemasaran gaharu. Perdagangan ini secara bertahap menimbulkan ancaman terhadap populasi gaharu di alam liar. Diperlukan identifikasi spesies, klasifikasi, dan penelitian yang akurat untuk memastikan budidaya dan perdagangan gaharu yang berkelanjutan. Pengabdian ini bertujuan untuk mengedukasi para pelaku industri gaharu di Pulau Lombok mengenai status terkini populasi spesies penghasil gaharu liar, termasuk dinamika perdagangan gaharu global secara keseluruhan. Edukasi yang dilakukan menggunakan pendekatan praktis dan konseptual dengan metode Focus Group Discussion (FGD) kerjasama FMIPA Universitas Mataram dan CSEAS Kyoto University, Jepang. Lokasi pengabdian yang dipilih adalah di Desa Orong, Desa Pusuk, dan Ampenan. Tim Pengabdian kepada Masyarakat telah melakukan edukasi agar khalayak sasaran memiliki peningkatan pengetahuan standarisasi kualitas gubal gaharu dalam rangka menjaga keberlanjutan pemasaran gaharu ke pasar internasional, serta usaha-usaha menjaga kelestarian pohon gaharu di Pulau Lombok
