ABSTRACT
Bamboo can be used as an alternative raw material to replace wood. Bamboo is a fast-growing plant that requires quality improvement. One type of bamboo that has not been utilized optimally is sembilang bamboo. Quality improvement can be done through heat modification. Heat treatment can improve the mechanical properties of a material but can cause discoloration. This study aimed to determine the effect of heat treatment on the discoloration of sembilang bamboo. This research was conducted by giving sembilang bamboo heat treatment at 180°C for 3 hours and 6 hours. The results obtained were sembilang bamboo, after heat treatment for 3 hours and 6 hours became darker than the control. The longer the heating time, the greater the value of the color change.

ABSTRAK
Bambu dapat dijadikan sebagai bahan baku alternatif pengganti kayu. Bambu termasuk tanaman cepat tumbuh yang memerlukan peningkatan kualitas. Salah satu jenis bambu yang belum dimanfaatkan secara optimal adalah bambu sembilang. Peningkatan kualitas dapat dilakukan dengan cara modifikasi panas. Perlakuan panas dapat meningkatkan sifat mekanis suatu bahan namun dapat menyebabkan perubahan warna. Tujuan penelitian ini adalah mengetahui efek perlakuan panas terhadap perubahan warna bambu sembilang. Penelitian ini dilakukan dengan memberikan perlakuan panas pada bambu sembilang dengan suhu 180°C selama 3 jam dan 6 jam. Hasil yang didapatkan adalah bambu sembilang setelah perlakuan panas selama 3 jam dan 6 jam menjadi lebih gelap dibandingkan kontrolnya. Semakin lama waktu pemanasan maka nilai perubahan warnanya semakin besar.
