Abstract
Teknik penyambungan telah banyak dilakukan untuk menyambung atau menyatukan dua material baik logam logam maupun non logam. Salah satu teknik penyambungan dua material ialah adhesive joint. Adhesive joint merupakan teknik penyambungan dengan menggunakan temperatur rendah yang dimana dibutuhkan perekat polimer. Perekat sendiri terdiri dari berbahan alam dan sintetis. Penggunaan bahan-bahan sintetis sangat mencemari lingkungan, ketersediannya semakin terbatas dan semakin mahal. Pada penelitian ini dilakukakn investigasi mengenai pengaruh variasi bio based adhesive terhadap kekuatan peeling dan shearing kayu pinus pada adhesive joint. Metode yang dilakukan adalah metode eksperimental dan pengujian yang dilakukan untuk mengetahui kekuatan peeling dan shearing adalah pengujian peeling dan shearing. Variasi bio based adhesive yang diujikan adalah getah pohon karet, nangka dan sukun. Nantinya adhesive joint berbahan bio based adhesive ini akan dibandingkan dengan adhesive sintetis adalah epoxy. Pengujian peeling dan shearing menggunakan ketebalan adhesive ± 0,1 mm dan kecepatan pembebanan yang terkontrol sebesar 1 mm/min. Pada kekuatan peeling dan shearing hasil tertinggi didapat bio based adhesive berbahan getah pohon karet, lalu getah pohon nangka dan sukun. Jika dibandingkan dengan adhesive sintetis, epoxy, memiliki kekuatan paling tinggi dibandingkan bio based adhesive pada penelitian ini. Namun bio based adhesive memiliki keunggulan lama sambungan yang lama dan ketersediannya yang melimpah dibandingkan adhesive sintetis. Pengaruh bio based adhesive pada adhesive joint dikarenakan adhesive joint memiliki kemampuan ikat antar permukaan melalui karakteristik seperti kandungan polimer dan viskositas masing-masing getah. Patahan yang terjadi pada spesimen adalah patahan campuran, dimana terjadi patah adherent, adhesive, dan juga cohesive yang membuktikan bahwa kekuatan adhesive dan adhesive serta adhesive dan adherent sama kuat.
English Abstract
Joining technique has been widely applied to connect or integrate two materials both metals and non-metals. One of the joining technique to integrate two materials is adhesive joint. Adhesive joint is a type of joining techniques that uses low temperature where adhesive polymer is needed. Adhesive itself is classified into natural and synthetic material. The utilization of synthetic material itself is very harmful to the environment, the availability is becoming more limited and is becoming more expensive. The study is done to investigate the effect of variation of bio-based adhesive to the peeling and shearing strength of the pine wood on the adhesive joint. The method used in the study is the experimental methods and the type of testing conducted to determine the peeling and shearing strength is peeling and shearing test. The tested bio-based adhesive variations are rubber tree sap, jackfruit and breadfruit. Subsequently, the adhesive made from bio-based adhesive joint will be compared with the synthetic adhesive counterpart, that is epoxy. The peeling and shearing test uses ± 0.1 mm of adhesive thickness and a controlled loading speed of 1 mm / min. The highest peeling and shearing strength obtained in sequence is bio-based adhesive made from the sap of rubber trees followed by jackfruit and breadfruit tree sap. Compared with synthetic adhesive counterpart, the epoxy still has the highest strength. However, bio-based adhesive has an advantage of a durable connection time and and has an abundance in quantity over synthetic adhesive. Effect of bio-based adhesive on the adhesive joint because the adhesive joint has bonding capability between material’s surfaces through characteristics such as polymer content and viscosity of each sap. Fracture occurring in the specimen is a mix fracture, where adherent, adhesive and cohesive fractures occur, indicating that the strength of adhesive and adhesive and adhesive and adherent is equally strong.
