Abstract
Penelitian ini memiliki tujuan untuk mengevaluasi koefisien gesek dari resin acrylic yang di reinforced oleh cellulose acetat serta mengkaji pengaruh resin acrylic reinforced cellulose acetate, coconut shell powder, dan coconut fiber terhadap sudut ulir pada mekanisme self locking bolt untuk abutment pada dental implant. Penggunaan material reinforced pada resin acrylic ini diharapkan untuk dapat meningkatkan koefisien gesek material tersebut sehingga material tersebut dapat meningkatkan kemampuan self locking mechanism yang nantinya akan dibuat dari material ini. Dalam penelitian kali ini, metode pengujian akan dilakukan dengan cara pemvariasian specimen dengan menggunakan fraksi massa. Pemvariasian akan dilakukan pada tahap pembuatan specimen resin acrylic ketika dicampur dengan yang pertama cellulose acetate, kemudian coconut shell powder, dan yang terkahir dicampur dengan coconut fiber. Alat uji yang digunakan dalam penelitian kali ini adalah Tribometer Anton Paar dan PASCO. Hasil studi sebelumnya telah membuktikan bahwa penambahan penguat cellulose acetate pada material serbuk kayu, sekam padi, dan tempurung kelapa akan menaikan koefisien gesek dari material tersebut. Sehingga diharapkan hal yang sama akan dapat disimpulkan dari penelitian kali ini. Dari koefisien gesek yang didapatkan, bisa ditemukan nilai dari sudut ulir yang diperlukan untuk mendaptkan sifat self locking bolt mechanism sehingga abutment yang dibuat dari material ini akan kuat dan tidak mudah lepas dari socket nya.

This study aims to evaluate the friction coefficient of acrylic resin reinforced by cellulose acetate and to examine the effect of acrylic reinforced cellulose acetate, coconut shell powder, and coconut fiber resin on the thread angle on the self locking bolt mechanism for abutment on dental implants. The use of reinforced material in acrylic resin is expected to be able to increase the friction coefficient of the material so that the material can increase the ability of the self-locking mechanism which will later be made from this material. In this study, the test method will be carried out by modifying specimens using mass fractions. Variation will be carried out at the stage of making acrylic resin specimens when mixed with the first cellulose acetate, then coconut shell powder, and the last one mixed with coconut fiber. The test equipment used in this study is the Anton Paar Tribometer and PASCO. The results of previous studies have proven that the addition of cellulose acetate enhancers to wood powder, rice husks, and coconut shell materials will increase the friction coefficient of these materials. So it is hoped that the same thing will be concluded from this research. From the friction coefficient obtained, it can be found the value of the thread angle that is needed to obtain the properties of the self locking bolt mechanism so that the abutment made of this material will be strong and not easily detached from the socket.
