Abstract

Pulau Kassa merupakan salah satu kawasan suaka alam yang di dominasi tipe hutan pantai dengan keunikan berupa jenis satwa endemik pulau berupa burung Gosong /Maleo (Famili Megapodiidae). Penelitian ini bertujuan untuk mengetahui jumlah populasi dan karakteristik habitat Burung Gosong Kelam (Megapodius freycinet). Pengambilan data jumlah sarang burung gosong di lokasi penelitian dilakukan dengan cara sensus yang di kombinasikan dengan metode jalur garis transek. Karakteristik habitat yang di nilai adalah jumlah sarang, karakteristik fisik dan kimia tempat bertelur, kondisi vegetasi sekitar sarang, bentuk dan dimensi sarang, sifat tanah, suhu dan kelembaban. Dari hasil penghitungan sarang di lokasi penelitian ditemukan sebanyak 86 buah gundukan sarang burung Gosong Kelam yang terbagi menjadi dua jenis sarang yaitu sarang aktif sebanyak 59 sarang dan sarang tidak aktif 27 sarang. Perkiraan jumlah populasi burung Gosong Kelam sebanyak 118 ekor. Vegetasi dominan untuk tingkat pohon yaitu jenis Besi Pantai (Pongamia pinnata) sedangkan vegetasi tingkat tiang, pancang dan semai di dominasi oleh jenis Eboni (Diospyros celebica). Parameter karakteristik fisik dan kimia sarang burung memiliki pengaruh nyata terhadap suhu di dalam sarang, ancaman dan gangguan yang terjadi pada kawasan ini cukup tinggi yaitu berupa gangguan habitat oleh aktifitas manusia, perburuan satwa dan introduksi jenis eksotik.

Abstract

Indicators of surface roughness and surface-free energy can represent the improvement in wood surface quality. In this study, those two indicators were used to determine the change in the samama (Anthocephalus macrophyllus) wood surface following two modification steps, namely impregnation and heat treatment. The first step was boron impregnation in two forms applied separately, i.e., boric acid and borax. The second step was impregnation of methyl methacrylate followed by heat treatment at 90°C and 180°C. Surface roughness was determined following the ISO 4287:1997 standard, and surface free energy was analyzed using the Rabel Method. The results showed that the radial surface of samama wood naturally had a lower roughness than the tangential surface. Impregnation with boric acid, borax, and methyl methacrylate increased the wood surface roughness. However, heat treatment at 180°C tended to smooth the rough surface. Total surface free energy was altered after borax and methyl methacrylate impregnation. However, heat treatment seemingly withdrew the alteration. The polar components and dispersion contributed to total surface free energy with different compositions. In this study, the change in surface roughness was not congruent with the change in total surface free energy. Keywords: boron, heat treatment, impregnation, samama, surface free energy
