      Abstract
      Getah pohon pinus merupakan hasil hutan yang sangat penting dan mempunyai nilai ekonomi yang tinggi. Berbagai metode penyadapan yang berkembang bertujuan untuk meningkatkan produksi getah. Pengujian dengan menggunakan metode non-destruktif testing (NDT) berbasis gelombang suara biasa digunakan untuk menduga kondisi internal dalam mengevaluasi kualitas pohon di lapangan. Penelitian ini bertujuan untuk mengevaluasi karakteristik kecepatan rambatan gelombang suara pada kayu pinus sadapan dan kaitannya dengan produksi getah berdasarkan penyebaran jumlah dan diameter saluran resin. Penelitian ini dilakukan pada tegakan pinus sebanyak 72 pohon yang terdiri atas 36 pohon disadap, dan 36 pohon lainnya disadap dengan penambahan stimulansia. Alat yang digunakan adalah SylvatestDuo untuk mengukur kecepatan gelombang suara, kadukul untuk penyadapan dengan metode quarre atau koakan dan bor riap untuk pengambilan sampel anatomi.
       
      Resin form pine trees are important forest products that have a high economic value. Various tapping methods have been developed to improve productivity of the pine resin. On the other hand, the method of non-destructive testing (NDT) based on sound wave propagation have been known and used widely to estimate internal quality of wood and can be used since in-situ evaluation of standing trees. The aim of this study was to evaluate the characteristics of the sound wave velocity in relation to pine resin productivity as well as the anatomical properties of frequency and diameter intercellular of resin. The research was conducted on 72 pine trees consisted of 36 trees which were tapped by the quarre method and 36 other trees were tapped by the quarre method plus giving the chemical stimulants. The main equipment used were NDT tool of Sylvatest-Duo, "kadukul" for tapping in quarre method, and increment borer to take anatomy sample.
