Teknologi pengawetan kayu dengan metode infus dan bandage-wrapping pada pohon berdiri yang masih hidup merupakan metode baru dalam pengawetan kayu. Metode ini memiliki keunggulan dapat mengawetkan kayu berukuran besar secara mudah. Kayu utuh berukuran besar dibutuhkan untuk bahan baku pembuatan Jalur, yaitu, perahu tradisional khas daerah Riau. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan pengawetan kayu pada pohon berdiri terhadap karakteristik kayu, terutama sifat kimia dan sifat mekanisnya. Masing-masing sebanyak dua pohon dari jenis kayu alternatif bahan baku pembuatan Jalur yaitu Bintangur (Callophyllum soulattri Burm.f.) dan Balam (Macaranga conifera (Rch.f. & Zoll) Mull.Arg) diawetkan menggunakan senyawa boron dengan metode infus dan bandage-wrapping. Sebagai kontrol, satu pohon dari masing-masing jenis juga ditebang dan diuji. Sampel kayu yang digunakan dibagi menurut posisi aksial pohon (pangkal, tengah, dan ujung) untuk diamati sifat kimia dan sifat mekanis dengan masing-masing tiga ulangan. Hasil penelitian menunjukkan bahwa posisi aksial mempengaruhi sifat kimia kayu Balam dan Bintangur secara siginifikan pada kadar lignin (30-36%) dan kadar alfa selulosa (48-52%). Secara umum, sifat mekanis yaitu Modulus of Rupture (MOR) dan Modulus of Elasticity (MOE) meningkat secara signifikan setelah diawetkan, kecuali pada Bintangur untuk metode bandage-wrapping. Hasil analisis sidik ragam dan uji lanjut menunjukkan bahwa perlakuan infus memberikan pengaruh nyata yang positif terhadap sifat kimia dan mekanis kayu Bintangur, sehingga pohon Bintangur yang telah diawetkan menggunakan metode infus dapat direkomendasikan sebagai alternatif bahan baku pembuatan Jalur.

Saat ini keberadaan kayu jenis meranti merah, kulim dan mersawa sebagai bahan baku pembuat jalur di Kabupaten Kuansing Provinsi Riau semakin langka, sedangkan kebutuhan kayu sebagai bahan pembuat jalur semakin tinggi. Oleh sebab itu diperlukan pemilihan jenis kayu alternatif yang memiliki persamaan sifat kuat dan awet dengan kayu jenis meranti merah, kulim, dan mersawa agar dapat memenuhi spesifikasi pembuatan jalur. Penelitian ini bertujuan mempelajari efektivitas pengawetan kayu balam dengan teknik infus dan bandage terhadap rayap kayu kering. Balam (Macaranga conifera Muell. Agr.) dipilih sebagai kayu alternatif untuk membuat jalur karena saat ini masih banyak ditemukan namun belum banyak dipakai untuk pembuatan jalur. Hasil pengamatan di lapangan menunjukkan bahwa jalur yang disimpan di darat mendapatkan serangan rayap kayu kering, sehingga diperlukan pengawetan jalur agar tidak terserang organisme perusak kayu (OPK) khususnya rayap kayu kering. Pengawetan pohon berdiri dengan senyawa boron komplek dengan teknik infus dan bandage dipilih untuk meningkatkan kelas keawetan kayu balam. Pengujian ketahanan kayu terhadap serangan rayap kayu kering dilakukan sesuai metode SNI 7207-2014. Data diolah dengan menggunakan rancangan faktorial acak lengkap. Hasil analisis menunjukkan bahwa pengawetan dengan teknik infus dan bandage berbeda nyata terhadap pengurangan berat dan mortalitas rayap. Pengamatan derajat serangan secara visual pada kontrol dan teknik infus yaitu 40 (tahan) yang nilainya lebih rendah dibandingkan teknik bandage 70 (sedang). Mortalitas pada teknik infus lebih tertinggi yaitu 90,67% dibandingkan kontrol 86,08% dan bandage 61,75%. Teknik pengawetan dengan teknik infus menunjukkan kandungan boron yang lebih tinggi dibandingkan dengan teknik bandage.
