Buku ini memberi pendedahan berkenaan pengenalan berkenaan Asas Pneumatik, Sistem Pneumatik, Elektro-Pneumatik, Asas Hidraulik dan Sistem Hidraulik yang dipraktikkan dalam Industri pada masa ini. Buku ini memfokuskan kepada asas pengenalan yang merangkumi teori-teori asas pneumatik, elektro-pneumatik, hidraulik dan pam hidraulik. Buku ini juga mengetengahkan simbol-simbol, komponen-komponen, dan litar-litar yang digunakan di dalam Sistem Pneumatik dan Hidraulik serta aplikasinyanya dalam Industri dan juga komponen-komponen yang diperlukan untuk melengkapkan sesuatu litar pneumatik, elektro-pneumatik dan hidraulik. Buku ini juga turut membincangkan tentang aras dan kedudukan setiap komponen mengikut kumpulan bagi litar pneumatik, elektro-pneumatik dan hidraulik. Di akhir bab buku ini menceritakan tentang teori-teori pam dan pengiraan yang terlibat bagi pam hidraulik.

A molded expanded polystyrene (EPS) cushion is a flexible, closed-cell foam that can be molded to fit any packing application and is effective at absorbing shock. However, the packaging waste of EPS cushions causes pollution to landfills and the environment. Despite being known to cause pollution, this sustainable packaging actually has the potential to reduce this environmental pollution because of its reusability. Therefore, the objective of this study is to identify the accurate design parameter that can be emphasized in producing a sustainable design of EPS cushion packaging. An experimental method of drop testing and design simulation analysis was conducted. The effectiveness of the design parameters was also verified. Based on the results, there are four main elements that necessitate careful consideration: rib positioning, EPS cushion thickness, package layout, and packing size. These parameter findings make a significant contribution to sustainable design, where these elements were integrated directly to reduce and reuse packaging material. Thus, it has been concluded that 48 percent of the development cost of the cushion was decreased, 25 percent of mold modification time was significantly saved, and 27 percent of carbon dioxide (CO2) reduction was identified. The findings also aided in the development of productive packaging design, in which these design elements were beneficial to reduce environmental impact. These findings had a significant impact on the manufacturing industry in terms of the economics and time of the molded expanded polystyrene packaging development.
