      Abstract
      Informasi tentang perubahan struktur anatomi penyusun batang bambu setelah dikeringkan masih sangat terbatas, padahal sangat diperlukan untuk mendukung pemilihan proses dan kondisi pengeringan yang paling tepat. Penelitian ini bertujuan mempelajari struktur anatomi batang atau bilah bambu tamiang (Schizostachyum blumei) pada kondisi segar, kering udara dan kering oven. Bahan yang digunakan adalah 3 batang bambu tamiang yang berasal dari kebun masyarakat di daerah Semin, Wonosari, Gunungkidul, Yogyakarta umur 10 tahun. Struktur anatomi diamati secara makroskopis menggunakan USB dan mikroskop digital Keyence VHX 7000, lalu dianalisis dengan bantuan software J-image. Parameter yang diteliti meliputi kadar air, laju pengeringan, tebal bilah, porsi ikatan pembuluh dan jaringan parenkim dasar serta dimensi ikatan serat dan metaxylemnya. Hasil penelitian menunjukkan setelah dikeringkan, kadar air dan tebal batang bambu berkurang, namun komponen struktur anatomi utama penyusun bambu tidak berubah dan tidak mengalami perubahan bentuk. Tebal bilah menyusut sesuai dengan perubahan nilai kadar air. Penyusutan tersebut berkorelasi dengan menyusutnya ikatan serat yang ada didalam ikatan pembuluh.
       
      Information regarding changes in the anatomical structure of bamboo culms after drying is very limited, even though it is very necessary to support the most appropriate drying conditions. This research aims to study the anatomical structure of tamiang bamboo (Schizostachyum blumei) culms under three different conditions i.e. fresh, air-dried and oven-dried. The materials used were 3 culms of the 10-year-old tamiang bamboo from a community garden in Semin, Wonosari, Gunungkidul, Yogyakarta. The anatomical structure was analyzed macroscopically using a USB and confirmed by a Keyence VHX 7000 digital microscope, then analysed by using J-image software. Parameter studied consists of moisture content, drying rate, culm’s thickness, portion of vascular bundle and ground parenchyma tissue as well as the size of fiber bundle and metaxylem. After drying it showed that moisture content and thickness of the bamboo culm decreased, however the type and the shape of the main anatomical components did not change significantly. The thickness of bamboo culm decreases according to moisture content, and this shrinkage is correlated with the shrinking of the fiber bundles in the vascular bundle.
