Abstract

Penggunaan balok kayu untuk keperluan struktur masih berorientasi pada kayu dari jenis dan mutu yang bagus, sehingga ketersediaan kayu ukuran besar dengan mutu baik menjadi semakin terbatas. Di sisi lain, serat GFRP (Glass Fiber Reinforced Polymer) adalah material yang memiliki kekuatan yang tinggi dan mudah diaplikasikan, material ini telah digunakan sebagai komposit, salah satunya dengan beton. Oleh karena itu, pada penelitian ini akan dicoba kedua material tersebut sebagai komposit yang bertujuan untuk meningkatkan mutu kayu. Mutu kayu yang dimaksud adalah modulus elastisitas yang menjadi salah satu parameter penting untuk grading kayu. Evaluasi peningkatan mutu kayu dilakukan dengan meninjau nilai Modulus Elastisitas, dengan membandingkan nilai Modulus Elastisitas balok kayu tanpa GFRP dan dengan aplikasi GFRP. Evaluasi Modulus Elastisitas menggunakan metode Four-point Bending Test dari ASTM D-198 dengan mesin UTM. Didalam penelitian ini ditinjau 2 konfigurasi aplikasi GFRP yang akan diuji untuk dibandingkan, dengan masing-masing konfigurasi menggunakan 40 sampel uji balok kayu. Konfigurasi A, yang menggunakan 1 lembar GFRP yang ditempel dengan epoxy resin pada bagian bawah dari balok kayu dan konfigurasi B, yang menggunakan GFRP yang ditempel dengan epoxy resin pada 3 permukaan dari balok kayu menyamai huruf U. Berdasarkan hasil penelitian diketahui bahwa kayu yang diperkuat dengan GFRP pada penelitian ini mengalami peningkatan rata-rata Modulus Elastisitas sebesar 15% pada konfigurasi A dan sebesar 22% pada konfigurasi B. Penelitian juga menunjukan bahwa bidang lekat yang semakin banyak juga dapat meningkatkan mutu kayu./ The use of wooden beams for structural purposes is still oriented towards wood of good type and quality, so the availability of large size wood with good quality is becoming increasingly limited. On the other hand, GFRP fiber (Glass Fiber Reinforced Polymer) is a material that has high strength and is easy to apply, this material has been used as a composite, one of which is with concrete. Therefore, in this research, these two materials will be tried as a composite with the aim of improving the quality of wood. The wood quality in question is the modulus of elasticity which is one of the important parameters for grading wood. Evaluation of wood quality improvement is carried out by reviewing the Elastic Modulus value, by comparing the Elastic Modulus value of wood beams without GFRP and with GFRP application. Elastic Modulus Evaluation using the Four-point Bending Test method from ASTM D-198 with a UTM machine. In this research, 2 GFRP application configurations will be reviewed for comparison, with each configuration using 40 wooden beam test samples. Configuration A, which uses 1 sheet of GFRP attached with epoxy resin on the bottom of the wooden beam and configuration B, which uses GFRP attached with epoxy resin on 3 surfaces of the wooden beam equals the letter U. Based on research results, it is known that wood is reinforced with GFRP in this study experienced an average increase in the Modulus of Elasticity by 15% in configuration A and by 22% in configuration B. Research also shows that more adhesive areas can also improve wood quality.
