Abstract

Resin komposit adalah bahan restorasi yang sering digunakan karena bersifat estetis tinggi. Filler anorganik seperti glass silica sebagai salah satu komposisi penting dalam resin komposit memiliki kelemahan berupa non-degradable, proses energinya tergantung pada bahan bakar fosil, serta emulsi polutannya tinggi dan membahayakan kesehatan dan lingkungan membuat filler alami sebagai bahan pengisi alternatif diperlukan. Salah satu serat alami yang dapat digunakan adalah serat sisal (Agave sisalana). Penelitian ini bertujuan untuk mengetahui perbedaan kekuatan geser antara semen resin komposit nanosisal 60% Wt dan semen resin nanofiller komposit. Penelitian ini merupakan penelitian eksperimental laboratoris. Serat sisal selanjutnya diubah menjadi ukuran nano. Nanosisal dicampur dengan Bis-GMA, UDMA, TEGDMA, dan Champhorquinone. Semen resin nanofiller komposit (AllCem Core) sebagai kontrol. Sampel berjumlah 10 dibagi menjadi dua kelompok. Gigi premolar dipreparasi tumpatan kelas V lalu ditumpat menggunakan dua bahan tersebut. Kekuatan geser sampl diuji menggunakan Universal Testing Machine (UTM). Analisis data menggunakan uji Independent Sample T-Test. Hasil menunjukkan semen resin nanosisal komposit 60% memiliki rata-rata kekuatan geser 13,10  MPa, dan semen resin nanofiller komposit 4,92 MPa. Analisis data menunjukkan perbedaan yang signifikan (p=0,000). Kekuatan geser semen resin nanosisal komposit 60% lebih besar dibandingkan dengan semen resin nanofiller komposit.

Abstract

Composite resin has three main components: a resin matrix, filler particles (filler), and a coupling agent. The inorganic nature of composite resin filler particles contrasts with the organic components prevalent in tooth structure and some adhesives. Therefore, to increase adhesive, innovative composite materials containing organic fillers are required. The aim is to describe the effect of curing time (20, 30, and 40 seconds) on the microscopic adhesion strength of composite resins containing (a) nano sisal, (b) silane-treated hydroxyapatite nano sisal, and (c) Z350XT nanofiller (control) to dentin. This descriptive study investigated the potential of nano sisal, a sisal fiber-based filler in composite resin, as an alternative to conventional synthetic fillers. Samples were divided into three groups: nano sisal composite (Group A), nano sisal composite with a coupling agent (Group B), and Z350XT nanofiller composite (Group C). Premolar teeth were filled with all three composite groups and cured for 20, 30, and 40 seconds. Standardized samples were then extracted for microscopic adhesion observation via a Scanning Electron Microscope (SEM). SEM images of groups A, B, and C showed a gap in the adhesion between the composite resin and the tooth structure. The smallest adhesion distance in group A was at a curing time of 20 seconds (0.687 μm). Group B had a large adhesion distance at 20 seconds (15.747 μm). The smallest microleakege in group C was at 40 seconds of curing time. It was 0.644 μm. Microscopic examination using SEM reveals the presence of microscopic defects at the interface between the restoration and the tooth structure across all investigated curing times (20, 30, and 40 seconds).

Abstract

This research aims to design and implement a ball-throwing robot that is used to train goalkeeper skills, such as reflexes and the ability to read the direction of the ball. The main focus of the research is to develop a ball throwing system that can provide a variety of shots with high precision, as well as overcome the limitations of manual training that relies on the individual skills of the kicker. This ball-throwing robot is controlled through a smartphone using a Bluetooth HC-05 module as a means of communication, and is equipped with two DC spindle motors, two DC PG36 motors, and two DC 12V motors to regulate the direction and speed of the ball. The ball direction and rotation control uses PID (Proportional-Integral-Derivative) control to ensure stable and accurate ball launching. The system dynamically adjusts the ball speed and direction based on position and angle sensor feedback. Tests were conducted at three different distances, namely 5 meters (100% accuracy), 7 meters (100% accuracy), and 11 meters (80% accuracy). The test results show that this ball-throwing robot is able to deliver shots with high precision, move flexibly and quickly, and adjust the direction and speed of the ball effectively. The results of the ANOVA test (p < 0.005) showed a statistically significant difference in average firing accuracy at all three distances. This research makes a practical contribution to improving the effectiveness of goalkeeper training, as well as offering a more efficient solution in football training. This research makes a practical contribution in improving the effectiveness of goalkeeper training, as well as offering a more efficient solution in soccer training.
