The immobilization of xylanase via carbohydrate-binding module (CBM) onto PC-MNPs enhanced enzyme activity and stability, as well as improved enzyme recovery. Compared with free Xyn10D, derivatives showed specific activity 1.5 × higher in the xylan hydrolysis. Interesting, after 30 cycles of reuse, enzyme preparations showed a relative hydrolysis percentage of 50% of reducing sugar from xylan. This work addresses upgrading pineapple peel, agricultural waste to high value-added cellulose for enzyme immobilization as a strategy to enhance lignocellulosic biomass hydrolysis by simplifying enzyme recovery and opening possibility for continuous processes.The blockchain business model (BBM) has been widely discussed for its ability to disrupt the current system. However, the limited explanations of the previous studies led this study to apply system dynamics (SD) approach using a dynamic value system framework that consists of value creation, value capture, and value proposition based on a case study of ALKO Sumatra Kopi, a coffee cooperative in Jambi, Indonesia. All experiment interventions produced a significant effect on BBM behavior. However, the findings show that although multiple interventions exhibit better behavior, it produces an insignificant difference from single value sub-system involvement since the interplay in the system moves non-linearly and across value sub-systems. This study serves to enlighten the growing area of blockchain and business models through a BBM design and experimentation through the approach, which identifies the value distribution of the system as well as raises dynamic complexity. The dynamic simulation study also can be a rationale for identifying the most plausible initiative to develop firm competitiveness over time.The Paris Agreement emphasizes the importance of reducing carbon emissions through a renewable energy transition. Many countries including Indonesia have ratified the agreement into their national regulations to contributes to the climate change solution. We use multi-layered approach to analyze the dynamic of energy transition by demonstrating the energy transition process in Indonesia using Actor Interaction analysis, Dilemma analysis, and System Analysis. We found that the energy transition ecosystem in Indonesia is still in experimental phase. Therefore, we have chosen a bottom-up approach, systematically uncovering actor interactions within and across systems. We also found that local government encounter dilemmatic situation in order to balance between smooth energy transition process and ensuring stable socioeconomic condition. The system dynamic simulation has proven to be vital addition to Drama Theory and Graph Model for Conflict Resolution—offering temporal perspective that is fundamental for decision-making process that concerns the ever-changing environmental situation.
