Abstract

Potensi hutan sebagai penghasil kayu semakin berkurang yang mengakibatkanberkurangnya pasokan kayu sebagai bahan baku. Untuk mengatasi hal tersebut perlu dicarisolusi dimana salah satunya adalah dengan memanfaatkan limbah-limbah yang dihasilkanoleh industri kayu yaitu limbah dari proses pengetaman (shaving) dan serbuk kayugergajian, yang dijadikan bahan baku papan partikel. Kurangnya peralatan dalam membuatproduk papan partikel, menjadi penghambat dalam pengembangan produk tersebut untukdijadikan industri rumah tangga. Penelitian ini mencoba membuat terobosan denganmembuat papan partikel dengan menggunakan peralatan sederhana atau konvensional.Hasil penelitian menunjukan bahwa sifat fisik papan partikel, yaitu kadar air, kerapatan,pengembangan tebal dan daya serap air berturut-turut sebesar 9,18%, 0,50, 22,76% dan39,76%. Sedangkan nilai kadar air, kerapatan, pengembangan tebal dan daya serap airberturut-turut untuk papan partikel dari bahan baku tipe serbuk kayu sebesar 12,14%,0,42, 29,22% dan 45,90%. Sifat keteguhan lentur statis yang meliputi keteguhan patah(MOR) dan kelenturan (MOE) untuk papan partikel dari bahan baku tipe shaving sebesar85,22 kg/cm2 dan 9.284,82 kg/cm2, sedangkan untuk papan partikel dari bahan baku tipeserbuk kayu sebesar 57,42 kg/cm2 dan 4993,14 kg/cm2.Keywords : papan partikel, limbah, kayu, sifat fisik, sifat mekanik

This study aims to determine the type and characteristics of the fruit-producing trees in Panoghan zone and Sialang Layang zone of the Forest Reserve of  Kenegerian Rumbio. This research was conducted by using the method of track / transect with a width of 20 meters and a length of 500 meters. The transect position in the field was determined by using Purposive Sampling technique. Based on observations from both transects, 15 species of fruit-producing trees with the number of individuals 58 fruit-producing trees were found , which each transect has different individual number. Results of tree species diversity index of fruit-producing trees in Panoghan zone is 1.96 and Sialang Layang Zone is 2.3, which means included in the medium category.Keywords: Identification of Species,Fruit- Producing Trees, Species Diversity Index, Forest Reserve of  Kenegerian Rumbio
