Abstract: Population growth affects the increase in electrical energy demand in Indonesia. The energy is used to fulfill daily and industrial needs for improving welfare and sustainably advance society. Nuclear power plants (NPPs) are technologically advanced, reliable, and environmentally friendly electricity generators that can significantly reduce climate change. Current public policies related to the use of NPPs in Indonesia tend to bring the realization of nuclear power plants closer. This study aims to provide an overview of the development of public policies related to the use of NPPs in Indonesia. This study uses qualitative methods based on analysis of secondary data collected from various sources and literature. Data analysis is done by selecting, organizing, and presenting as a collection of information to be used for drawing conclusions. The results of the study indicate that the public policy perspectives have progressed towards supporting the use of NPP in supporting sustainable development. The increasing knowledge of public policy perspectives on the utilization of NPPs in Indonesia is important for educational and dissemination purposes as part of efforts to strengthen public acceptance.

Abstract: In the midst of the information communication technology development as well as massive disruptions such as the Covid-19 pandemic, big data analysis plays an important role in the supply chain. The aim of this study is to look at how big data analytics research and applications have progressed in the supply chain in Indonesia. While most studies typically have focused on the specific application of big data analytics in a specific industry, this paper attempts to conduct a systematic investigation to comprehend the larger picture. The method used is a systematic analysis of the Scopus database using search queries relevant to big data analytics on the supply chain in a specific Indonesian context. According to the study's findings, big data analytics is implemented in many industrial supply chains, including manufacturing, oil and gas, services, and agriculture. This paper contributes to the literature by investigating the use of big data analytics in the supply chain in Indonesia.

Abstract: The rising demand for food and agricultural products encourages agricultural firms to innovate in both quantity and quality. The specific aim of this study is to investigate the innovation practices in food and agricultural firms. This study takes the case study method by using the cases of the Malcolm Baldrige National Quality Award (MBNQA) recipients engaged in food and agricultural products, namely Cargill Corn Milling (CCM) and Sunny Fresh Foods (SFF). The data is drawn mainly from Baldrige Application Summary, supplemented by other sources such as the company website as a compliment. This study suggests that innovation is strong in these two firms, both technologically and organizationally. It is indicated by the implementation of sophisticated technology such as automation and robotics and the implementation of organizational innovation in the form of i2i (ideas to innovation) R&D expertise in food products. This study offers important lessons learned on innovation for the agricultural firms to meet current demand while also developing the firm's capability to innovate.

Abstract: This paper presents an investigation of the dimension variations on modular magnetorheological (MR) valve with meandering flow path structure. The size variations including the inner and outer radius of the valve at radial path. The first step is conducting FEMM (Finite Element Method Magnetics) to find out the density of magnetic flux on MR valve. The obtained magnetic field density is applied to steady state models to predict pressure drop. To determine the best configuration, pressure drop and operation range are the objective of the selection process. Based on the results, MR valve with 2.75 mm inner radius radial and 9 mm outer radius radial was chosen as the best MR valve design if compared to the other MR valve designs. The results obtained from the MR valve with 2.75 mm inner radius radial and 9 mm outer radius radial are 1.79 Mpa for the pressure drop and 6.68 for the operational range. Keywords: modular magnetorheological valve, optimization, objective function, smart materials
