Abstract

Penelitian mengenai inovasi produk dalam material komposit merupakan urgensi, salah satu industri yang memiliki potensi inovasi adalah wood-based panels (WBPs) khususnya papan partikel. Selama ini kayu masih menjadi bahan utama dalam produksi papan partikel. Akan tetapi kesadaran konsumen mengenai dampak penggunaan kayu secara berlebih mendorong industri ini untuk mencari alternatif pengganti kayu. Pada penelitian ini dilakukan review yang bertujuan untuk mengetahui, membandingkan, dan mencari peluang serat alam non-kayu sebagai material dalam papan partikel. Berdasarkan 11 jurnal yang telah diulas dari berbagai peneliti di dunia didapatkan hasil bahwa penggunaan serat alam non-kayu adalah feasible jika material tersebut memiliki karakteristik mekanis yang mirip dengan kayu. Serabut kelapa merupakan serat alam yang memiliki potensi menjadi material pengganti kayu pada produk papan partikel. Modulus of elasticity (MOE) dan modulus of rupture (MOR) Spesimen yang telah diuji oleh berbagai peneliti menunjukkan bahwa sifat mekanis serabut kelapa memiliki kemiripan dengan kayu dengan beberapa penyesuaian seperti homogenisasi ukuran partikel dan jenis perekat yang digunakan. Maka dapat disimpulkan bahwa serabut kelapa merupakan salah satu material potensial yang membutuhkan pengembangan lebih lanjut.

Abstract

Conventional and electric wheelchairs are often unable to fully meet the needs of users with upper-body movement limitations, particularly in terms of device control and surrounding environment detection. In addition, existing smart wheelchairs are generally expensive, difficult to customize, and have not been widely accepted by users. This study aims to design a smart wheelchair that integrates voice control, joystick control, and an obstacle detection system to enhance user safety, accessibility, and independence.The design process was carried out systematically through functional decomposition, concept development, and design selection for the frame structure, control system, and motor drive circuit components. The system was developed using an Arduino microcontroller, Voice Recognition Module V3.1, HC-SR04 ultrasonic sensors, an analog joystick, and an L298N motor driver. The prototype successfully integrated two control modes with an aluminum frame capable of supporting loads of up to 150 kg. The obstacle detection system operated effectively within a 50 cm radius to automatically prevent collisions. However, the voice recognition module still encountered technical issues, such as errors during voice training, indicating the need for more reliable hardware solutions.The results demonstrate that the proposed design has significant potential to support the mobility of people with disabilities through enhanced safety features and flexible control mechanisms. Further development is required to improve the reliability of the voice recognition system and to expand the application of assistive technologies for improving users’ quality of life.
