Abstract

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.

Abstract

Rapid Prototyping (RP) technology is rapidly advancing and plays a crucial role in various sectors. One of the methods used in this technology is Fused Deposition Modelling (FDM), which involves the process of melting thermoplastic material using an extrusion mechanism. FDM-type 3D printers control nozzle movements through computerization, resulting in various directions of movement, including parallel to the x-axis (0°), y-axis (90°), and diagonal (45°). Differences in these directions impact the mechanical characteristics of flexural strength in the produced prints. This research involves a bending test according to ASTM D790 standards, using the Beste KJ-1065 testing machine. Test specimens were created in three different types, with nozzle direction settings that differ in external infill angle offset and internal infill angle offset, specifically at 0° (parallel to the X-axis), 45° (parallel to the diagonal), and 90° (parallel to the Y-axis). The research results show that the nozzle direction in FDM-type 3D printers also influences the flexural strength of the produced products. The highest flexural strength was found in products with a 0° nozzle direction, reaching 65.21 MPa, while the lowest occurred in products with a 90° nozzle direction in the horizontal condition, reaching 45.18 MPa. Key words : Rapid prototyping, 3D Printing, Fused Deposition Modelling

Abstract

Pada akhir 2015, era persaingan bebas Masyarakat Ekonomi ASEAN (MEA) telah diberlakukan. Artinya dunia usaha di Indonesia memasuki babak baru persaingan bebas, baik produk maupun tenaga kerja. Menjawab tantangan tersebut, maka perlu peningkatan salah satunya disektor pendidikan. SMK 1 Karangdadap merupakan sekolah menengah kejuruan di Kabupaten Pekalongan. Pada jurusan TITL telah mempelajari pengendalian motor listrik 1 dan 3 fasa. Tetapi, kompetensi tersebut dirasa masih kurang karena industri saat ini banyak menggunakan sistem elektro pneumatik sebagai penggerak mesin industri. Di jurusan tersebut telah memiliki beberapa alat praktikum yang menunjang pembelajaran, tetapi belum memiliki alat praktikum sistem pneumatik. Jadi untuk membekali siswa tentang pengetahuan sistem pneumatik, pembelajaran dilaksanakan hanya dengan cara teori. Padahal kebanyakan lulusan yang bekerja di industri pasti menjumpai sistem pneumatik pada mesin – mesin di industri. Oleh sebab itu perlunya pelatihan untuk meningkatkan skill elektro pneumatik pada kompetensi mengoperasikan sistem pengendali elektromagnetik bagi siswa SMK N 1 Karangdadap. Pada peleatihan ini menggunakan peraga dan jobsheet elektro pneumatik. Peserta pelatihan yang dinyatakan lulus oleh penyelenggara pada test akhir pelatihan maka mendapatkan sertifikat pelatihan. Pelatihan ini menggunakan metode pembelajaran Student Teams Achievement Division (STAD). Hasil Belajar pada pelatihan peningkatan skill elektro pneumatik yang barkaitan dengan ketuntasan siswa meningkat.

Abstract

This objective of this research was to assess the mechanical and physical properties of hybrid particleboard made from sengon wood (Falcataria moluccana) and betung bamboo (Dendrocalamus asper) treated with steam and used different ways of combining particleboard layer. Steam treatment was performed in the autoclave at 126 ºC for 60 minutes at a pressure of 0.14 MPa. The particleboard combinations were made based on face : core : back with three types of combinations, namely sengon particleboard, sengon : betung : sengon particleboard, and betung : sengon : betung particleboard. The boards were made of 30x30x0.9 cm³ dimensions using urea formaldehyde (UF) adhesive to achieve density of 0.6 g/cm³. JIS A 5908-2003 were used as references for the physical and mechanical properties examination. The resulting density and MC values were 0.61-0.63 g/cm³ and 10.18-10.85%, while the WA and TS values were 50.79%-74.07% and 8.81-21.84%. The MOE and MOR values produced were 331-1642 MPa and 4-12 MPa. From this study we can conclude that the hybrid particleboard made from a combination of betung : sengon : betung treated with steam was the most superior and proved to improve the mechcanical and physical properties of hybrid particleboard from sengon wood and betung bamboo. Keywords: betung bamboo, hybrid, particle board, sengon wood, steam.

Abstract

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

Abstract

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).
