Abstract
Kayu damar (Agathis Wood) merupakan bahan dasar dalam produk kerajinan Kayu. Salah satu proses pengolahan kerajinan kayu adalah proses bending menggunakan uap panas atau steam bending. Dalam proses steam bending agathis wood membutuhkan kestabilan uap yang optimal untuk melunakkan kayu. Namun, dalam sistem steam generator memiliki risiko overheating pada heater apabila level air yang ada di dalam tank steam generator itu rendah (low) dan terbentuknya uap yang terlalu basah apabila level air dalam tanki terlalu penuh (high). Untuk mengatasi permasalahan tersebut, perlu adanya sistem kontrol level air pada tanki penghasil steam untuk proses pembengkokan kayu. Tujuan sistem ini untuk menjaga kestabilan uap yang dihasilkan serta mencegah kerusakan komponen heater yang diakibatkan dari kekurangan air. Penelitian ini menggunakan sensor level air elektroda sebagai pendeteksi level air di dalam tanki steam generator. Ketika air terdeteksi rendah, sistem akan mengaktifkan relay untuk memerintahkan solenoid valve dapat mengisi air dari feed water tank menuju tanki steam generator, dan akan berhenti mengisi ketika level air telah mencukupi. Sensor flow meter digunakan untuk memantau laju aliran air dari feed water tank menuju tanki steam generator selama proses pengisian berlangsung. Berdasarkan hasil percobaan dari sistem ini, terciptanya sistem kontrol yang mampu menjaga level air dalam batas optimal secara konsisten, mampu meminimalkan potensi kerusakan heater, serta meningkatkan efisiensi penghasilan uap untuk proses steam bending.

Damar wood (Agathis Wood) is the basic material used in wood craft products. One of the wood crafting processes is steam bending, which uses hot steam. In the steam bending process, agathis wood requires optimal steam stability to soften the wood. However, in the steam generator system, there is a risk of overheating the heater if the water level in the steam generator tank is low and the formation of excessively wet steam if the water level in the tank is too high. To overcome this problem, a water level control system is needed in the steam generator tank for the wood bending process. The purpose of this system is to maintain the stability of the steam produced and prevent damage to the heater components caused by water shortage. This study uses an electrode water level sensor to detect the water level in the steam generator tank. When low water is detected, the system will activate a relay to command the solenoid valve to fill water from the feed water tank to the steam generator tank, and will stop filling when the water level is sufficient. A flow meter sensor is used to monitor the flow rate of water from the feed water tank to the steam generator tank during the filling process. Based on the results of experiments with this system, a control system has been created that is capable of maintaining the water level within optimal limits consistently, minimising potential damage to the heater, and increasing the efficiency of steam production for the steam bending process.
