Foaming of wood-fiber/plastic composites (WPC) with a fine-celled structure can offer benefits such as improved ductility and impact strength, lowered material cost, and lowered weight, which can improve their utility in many applications. However, foaming of WPC is still a poorly understood art. This paper presents a review of material published, which address the various critical issues particularly in extrusion foaming of WPC, and the proposed processing techniques and strategies, for producing artificial wood with enhanced properties.
Adanya asumsi bahwa bambu merupakan material dasar yang murah dan tidak memiliki harga jual,memicu kegelisahan beberapa kalangan untuk berinovasi menggunakan bambu sebagai bahan dasar. Salah satunya adalah Indonesian Bamboo Community yang dipimpin oleh Adang Muhidin yang mencoba berinovasi dengan membuat alat musik konvensional berbahan dasar bambu. Tulisan ini akan membahas proseskreatif yang dilakukan oleh sebuah komunitas bambu dengan metode penelitian kualitatif, yaitu penelitian yang menekankan pada kualitas atau hal terpenting dari sifat suatu benda, yang didalamnya tidak hanyameliputi pertunjukan musik saja tapi bagaimana membuat alat musik yang berbahan dasar bambu. ABSTRACTThe assumption that bamboo is a material cost basis and does not have a selling price, triggers anxiety in some quarters to innovate using bamboo as raw material. One of them is the Indonesian Bamboo Community led by Adang Muhidin who tried to innovate by creating a conventional musical instrument made from bamboo. This paper will discuss the creative process undertaken by a community of bamboo with qualitative research methods, the research emphasizes on the quality or the most important thing of the nature of an object, in which not only includes music performances alone but how to make a musical instrument made from bamboo.
