<p><span style="font-family: TimesNewRomanPS-BoldMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;"><strong>ABSTRAK</strong><br /><span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">Bambu betung (dendrocalamus asper) merupakan jenis bambu besar dan berbuluh tebal yang di Indonesia potensinya masih cukup melimpah. Bambu betung memiliki kesulitan dalam pengerjaan ukir. Pelaksanaan kegiatan ujicoba pembuatan aksesoris interior <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">dengan teknik ukir krawangan pada bambu betung ini, prosesnya terdiri dari: persiapan bahan <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">(pemotongan, pengawetan dan pengeringan), perancangan desain produk (sumber inspirasi, <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">sketsa alternatif dan gambar kerja), serta pembuatan produk (meliputi: pembentukan global<span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">/awal, pembuatan krawangan, pengukiran dan finishing). Dari hasil penelitian menunjukkan bahwa teknik pelobangan (krawangan) dengan bor 4 kali lobang kemudian diteruskan <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">dengan gergaji <span style="font-family: TimesNewRomanPS-ItalicMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;"><em>hand jigsaw </em><span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">didapatkan kecepatan rata-rata (4 x 5.1) + 20 = 40,4 detik untuk <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">ukuran lubang 3 – 4 cm, tebal 1,5 cm bentuk variasi lurus lengkung, pada kondisi bambu <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">setengah basah (magel). Ini berarti 5 kali lebih cepat dari pada pemahatan manual (209.1 <span style="font-family: TimesNewRomanPSMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;">detik), serta hasil yang didapat lebih rapi dan lebih bersih. Kondisi terbaik untuk pembuatan krawangan adalah kondisi setengah basah (<span style="font-family: TimesNewRomanPS-ItalicMT; font-size: 12pt; color: #231f20; font-style: normal; font-variant: normal;"><em>magel</em><span style="font-family: TimesNewRomanPSMT;
