Abstract

The composition of the adhesive content of Tannin Resorcinol Formaldehyde (TRF) is considered more environmentally friendly to use when compared to the phenol resorcinol formaldehyde (RPF) adhesive. In this study to test the strength of the adhesive, acacia (Acacia mangium) and pulai (Alstonia scholaris) were used. This study aims to determine: 1. The characteristics and quality of the adhesive composition of eucalyptus bark tannins, resorcinol and formaldehyde based on SNI 6/4567/1998; and 2. The strength of the gluing composition of eucalyptus bark tannins, resorcinol and formaldehyde on acacia and pulai wood syrup based on SNI 6/6049/1999. The research was conducted using a non-factorial Completely Randomized Design (CRD) consisting of 6 treatments of adhesive composition with 5 repetitions, in order to obtain 30 test samples. The data obtained from the research results were analyzed by means of variance using SPSS 20. Furthermore, if the variance results have a significant effect, further analysis will be carried out using Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results of the research that has been carried out, the six different adhesive compositions produce different values ​​in each treatment, except for treatment P1. P1 has the shape and appearance of a jelly-shaped adhesive so that it cannot be tested and applied to acacia and pulai wood glue. Treatments P2 to P6 can be applied and used for testing and bonding. The pH test and gelatinization test of all treatments were included in SNI 6/4567/1998, the P2 viscosity test did not pass SNI 6/4567/1998. The shear bond strength test was carried out to determine the strength of the adhesive referring to SNI 6/6049/1999, the average value of the best wet shear adhesion test in treatment P6 was 7.89 N/mm2 and the highest average value of shear bonding strength dry on P5 treatment of 26,09 N/mm2.

Abstract

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.

Abstract

Seiring dengan meningkatnya permintaan dunia terhadap komoditas getah pinus, maka salah satu upaya yang dapat dilakukan untuk meningkatkan produksi getah pinus yaitu menggunakan zat perangsang getah/stimulansia. Selama ini, dalam kegiatan penyadapan getah pinus digunakan stimulansia anorganik yang tetapi komponen utamanya adalah asam sulfat dan asam nitrat atau campurannya yang bersifat sebagai oksidator kuat yang dapat merusak kulit manusia, kayu dan lingkungan jika digunakan dalam jangka panjang dan secara berlebihan. Alternatif penggunaan stimulansia dari bahan alami yang aman, harga relatif murah, dan mudah didapat seperti lengkuas (Alpinia galanga) dan jahe (Zingiber officinale). Penelitian ini dilakukan untuk mengetahui pengaruh pemberian stimulansia ekstrak lengkuas dan jahe terhadap peningkatan produktivitas getah pinus. Hasil penelitian ini menunjukkan produktivitas getah yang paling tinggi dihasilkan oleh pohon pinus menggunakan stimulansia organik jahe konsentrasi 50% yaitu sebesar 11,15 g/koakan/hari. Kualitas getah pinus yang memiliki mutu terbaik dihasilkan oleh stimulansia jahe, sedangkan pada penggunaan stimulansia lengkuas memiliki mutu II berdasarkan SNI 7837:2016.  Stimulansia organik lengkuas dan jahe bersifat aman bagi kesehatan pekerja, pohon, dan lingkungan  sehingga keuntungan yang diperoleh akan lebih besar. Berdasarkan hal tersebut perlu dilakukan penelitian lanjutan untuk mengetahui analisis biaya penggunaan stimulansia organik terhadap stimulansia anorganik dalam upaya meningkatkan produktivitas getah pinus.
