Cellophane is a composite polymer material, made up of regenerated cellulose (usually derived from wood pulp) which has been chemically transformed into "viscose", then formed into a (1 mil thickness) transparent sheet through an extrusion process. Although primarily produced for the food industry, cellophane's use as a separator material in the silver-zinc secondary battery system has proved to be another important market. We examined 14 samples from five producers of cellophane, which are being evaluated as the separator material for a silver/zinc alkaline battery system in an autonomous underwater target vehicle. Our intent was to identify structural and/or chemical differences between samples which could be related to the functional differences seen in the lifetimes of these various battery separators. The unused cellophane samples were examined by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). Cellophane samples were cross sectioned (125-150 nm) using a diamond knife on a RMC MT-6000 ultramicrotome. Sections were examined in a Philips 430-T TEM at 200 kV. Analysis included morphological characterization, and EDS (for chemical composition). EDS was performed using an EDAX windowless detector.

There are many attempts to support the development of industry in Indonesia, especially on automotive sector, one of them is by replacing import components with local component products. Bushing is one of imported component that widely used on automotive application including motor strater. Bushing usually made of  copper alloy such as brass, bronz or babbit in a solid form by casting or extrusion process. In this research powder metal technology is used to process Cu-Al powder to become slide bearing of motor starter. It is expected that powder metal process not only increasing local content in automotive parts but also providing better quality by increasing life time of bushing compared to ordinary one. Cu-Al metal powder was compacted at various pressure, i.e: 250 MPa, 350 MPa and 450 MPa, and then all specimens were sintered at different temperatures : 4000C, 5000C dan 6000C for 1 hour.  After sintering specimens were air cooled to room temperature. After physical and mechanical test it can be deduced that bushing made by powder metallurgy method could increase its mechanical properties and as aresult improve its life time operation.
