A credenza is a type of furniture commonly utilized as a storage unit for various items, typically equipped with conventional physical locks. These locks, often made from iron, metal, or brass, pose a high risk of theft and require more time to unlock. This study proposes an alternative solution for enhancing storage security systems by incorporating Radio Frequency Identification (RFID) technology. The adoption of a keyless security system based on RFID aims to replace conventional physical locks, offering improved security and efficiency. The primary objective of this research is to evaluate the effectiveness of RFID technology and its practical application in credenza furniture. Experimental results using Medium Density Fibreboard (MDF) as the material indicate that the maximum functional door thickness is 50 mm, with an authentication time of 1.27 seconds. The production process yielded a credenza featuring an RFID Reader Box installed on the inner side of the door, positioned 100 mm from the top edge, and a locking component located on the inner left wall, 115 mm from its edge.

The application of CNC technology in the furniture industry has already become familiar, in addition to its use in the metal and plastic industries. HMR (High Moisture Resistant) panels, which had better moisture resistance than MDF (Medium Density Fiberboard), had also started to develop. However, few studies have investigated the effects of variations in machining parameters on the cutting quality of HMR boards. This study aimed to test the effects of machining parameters (cutting method and cutting depth) on the dimensions and surface roughness of the workpiece. Four schemes of machining parameter settings, namely conventional and climb methods with cutting depths of 2 mm and 4 mm, respectively, were performed with three repetitions each. After testing, it was found that the cutting method, cutting depth, and the interaction between the cutting method and cutting depth had not significantly affected the length and width dimensions of the specimen. However, the cutting method significantly influenced the final surface roughness of the specimen. The conventional cutting method with a cutting depth of 2 mm produced the best surface roughness, measuring 26.47 µm.

This study investigates the influence of cutting methods and feed rates on the dimensional accuracy and surface roughness of HMR (High Moisture Resistance) panels. The aim is to determine the optimal cutting parameters that yield precise dimensions and smooth surfaces in CNC machining. Two cutting methods—single and double passes—were applied using feed rates of 2, 4, and 6 m/min. Dimensional accuracy was measured using a digital caliper, while surface roughness was evaluated with a surface tester. The results indicate that the double-pass cutting method significantly improves both dimensional accuracy and surface finish. Statistical analysis using ANOVA revealed that feed rate has a significant effect on surface roughness (p < 0.05), whereas dimensional accuracy is primarily influenced by the cutting method. These findings provide practical insights for optimizing CNC machining processes in furniture manufacturing using HMR panels.

Utilization of composite boards for furniture has been widely used in order to substitute solid wood. Coating veneer (veneering) is a technique to improve the appearance of composite panel products, such as plywood. This research was conducted to determine the effect of the type of veneer and the mass of adhesive lath on the physical and mechanical properties of veneering plywood. The veneer used are from teak, mahogany and mindi. The adhesive used was polyvinyl acetate (PVAc) with a melting weight of 130 g/m2, 150 g/m2, 170 g/m2. The results showed that the type of veneer had no effect on the physical and mechanical properties of the composite board. The physical properties in the form of density are affected by the weight of the adhesive, the higher the amount of adhesive, the higher the density. Veneer delamination with glue spread of 150 and 170 g/m2 complies with JAS Type 2 standards. Veneer composite products with PVAc adhesives can be used in interior areas where there is frequent short term exposure to water. Keywords: adhesive, glue spread, plywood, veneer ABSTRAK Pemanfaatan plywood untuk furnitur telah banyak digunakan dalam rangka mensubtitusi kayu pejal.

The quality of furniture products is largely determined by the quality of the wood raw materials, particularly the degree of dryness and moisture content of the wood. Wood drying can be done naturally with sunlight or using a drying machine. Most research on drying machine design is still conventional with a continuous drying method, namely controlling the external temperature and the wood surface to keep it stable. The research aims to produce a Kiln Dry machine that can support intermittent drying by setting and monitoring temperature and humidity controls. Drying with the intermittent method has been proven to reduce defects that occur in wood. The process flow in this research includes system design, system simulation, system creation, and testing the results. The designed drying machine is capable of operating intermittently or continuously, with an outer size of 90 cm × 100 cm × 100 cm and a drying room of 70 cm × 80 cm × 80 cm, the walls are designed using rock wool insulation to maintain the temperature of the machine room. The results of the function test show that the machine is capable of reaching a temperature of 196 °C in 60 minutes, with an operating temperature limited to 115 °C. The five-stage intermittent drying test with a ramp time of 10 minutes and a soak time of 10 minutes showed that the temperature control system was able to follow the set value at each stage, although there was a temperature overshoot of 2-5ºC at each stage in the Intermittent test

The rapid adoption of digital manufacturing and smart CNC machining in furniture production has made the optimization of machining parameters for engineered wood panels increasingly important. High Moisture Resistance (HMR) panels are widely used because of their superior moisture resistance compared with Medium Density Fiber board (MDF). However, studies on CNC machining performance of HMR panels remain limited, particularly regarding dimensional accuracy and surface roughness. This study evaluates the effects of depth of cut and feed rate in CNC nesting on dimensional accuracy and surface quality of HMR panels. Four machining combinations were tested using depths of cut of 2 and 4 mm and feed rates of 33 and 66 mm/s, with three replications for each treatment. Specimen dimensions and average surface roughness (Ra) were measured after machining. The results show that depth of cut significantly affected dimensional accuracy, while feed rate significantly influenced surface roughness. The interaction between depth of cut and feed rate was not significant for specimen length, but was significant for specimen width and roughness. Optimal dimensional accuracy and surface quality were achieved using the lowest depth of cut (2 mm) in conjunction with the lowest feed rate (33 mm/s).
