Purpose – This purpose of the research is to investigate the process of manufacturing LDPE recycle thermoplastic composites with reinforcement oil palm empty fruit bunch (OPEFB) biomass microfillers.

Design/Methodology/Approach – Methods of physical and chemical modification of OPEFB fibers into the LDPE matrix and the addition of some compatibilizer such as MAPE and xylene process through melt blending can improve mechanical properties, electrical properties, biodegradability, and improve the morphology of composites.

Research Limitations/Implications – These composites are prepared by the following matrix ratio: filler (70:30)% and filler size (63, 75, 90, and 106) μm. The LDPE plastic is crushed to a size of 0.5–1 cm, then pressed with hot press free heating for 5 min and with a pressure of 10 min at 145 °C. Based on the characterization obtained, the tensile strength and the high impact on the use of 106 μm filler is 13.86 MPa and 3,542.6 J/m², and thermal stability indicates the degradation temperature (T₀) 497.83 °C. FT-IR analysis shows the presence of functional groups of cellulose and lignin molecules derived from TKKS collected in the composite.

Practical Implications – Based on the characterization obtained, this composite can be applied as furniture material and vehicle dashboard.

Originality/Value – Composites obtained from recycle of LDPPE plastics waste has some advantages such as good compatibility and high tensile strength. This composite used the OPEFB filler whose size is in micrometer, and so this product is different from other products.

The role of management control has not received sufficient attention in the literature on value creation so far. Therefore, this paper aims to investigate the role of control in value creation in industrial networks. More specifically, the aim is to examine the management and control of interfaces between key resources within and between firms, in the networks surrounding firms, when they attempt to create value. All the firms that take part in a value-creation process have both formal and informal control systems: these firms have budgets, specific routines, reward systems, and sanctioned “ways to behave.” The paper relates the Industrial Marketing and Purchasing (IMP) group's research on interaction, relationships, and networks with control literature, and presents a framework for controlling resource interfaces in a network setting. Two in-depth cases illustrate the role of control in value creation. The first case covers the development of a low-weight newspaper grade that Holmen and its paper mill Hallsta initiated. The second case examines the attempt to develop and commercialize a new, energy efficient pulping technology.
