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.

Abstract UNS No. T30407 is a high-carbon chromium cold-work tool steel containing vanadium (4.0%) and molybdenum (1.0%). Its carbon and vanadium form a vanadium carbide that provides war resistance many times greater than that of UNS No. T30403 (AISI Type D3). UNS No. T30407 was developed for applications where extreme abrasive wear is needed. Its many applications include briquetting dies and punches, brick mold liners, pottery, tools, broaches, meat-chopper plates and cold-extrusion dies. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-439. Producer or source: Tool steel mills.

Since environmental issues are becoming an integral part of business performances, policymakers and managers have started recognizing the importance of green innovation towards sustainable business performances. The role of the automotive parts industry is crucial in minimizing environmental degradation and promoting sustainable development. Yet few studies have focused on the connection between green entrepreneurial orientation and green innovation that may affect small and medium enterprise (SME) business performance. Therefore, this study aims to analyze the influence of green entrepreneurial orientation on green innovations, and its effects on sustainable business performances in the automotive parts industry in Thailand. The sample consists of 226 SMEs in the automotive parts industry in Thailand. The partial least square method (PLS-SEM) has been used for the analysis of data. The results of the study show that green innovations have the strongest influence on economic and environmental performances. This study contributes to resource-based view theory by incorporating green innovation as a strategic competency of SMEs’ performance. Further, green entrepreneurial orientation and green innovation can assist SME managers in understanding the factors leading to sustainable performance of businesses.
