Abstract
Purpose – The aim of this study is to determine the differences in the antimicrobial activity of katuk leaf (Sauropus androgynus (L.) Merr) against Escherichia coli.
Design/Methodology/Approach – The method used in this study was experimental posttest using a control group design. Analysis of the effect of katuk leaf was performed in the dilution method with 20%, 40%, 60%, 80%, and 100% concentration. The data were analyzed using one-way ANOVA test (α = 0.05) and was then tested using the least significant difference (LSD) test.
Findings – Bacterial colony counting that used total plant count found the average of E. coli amount at 20% of concentration (526.820 CFU/ml), 40% of concentration (449.380 CFU/ml), concentration of 60% (255.710 CFU/ml), concentration of 80% (194.110 CFU/ml), and at concentration 100% (168.600 CFU/ml). This study concluded that the katuk leaf extract at 20%, 40%, 60%, 80%, and 100% of concentration had antimicroba effect with significant influence. The 100% of concentration had the most significant effect compared with the other concentrations.
Research Limitations/Implications – Katuk leaf could be used as one of the alternative herbal choices that has a compound antimicrobial effect.
Originality/Value – This study increases the theoretical understanding of the difference of antimicrobial effectivity of katuk leaf extract (S. Androgynus (L.) Merr.) concentration against E. coli

Abstract
This chapter draws out lessons regarding how the diagnosis of urgent problems, the formation of ambitious and visionary goals, and the participation of stakeholders with critical innovation assets stimulate the cocreation of innovative solutions that promote the SDGs (Sustainable Development Goals), and how changemakers can lead and manage cocreated innovation processes. It considers the initiation of innovation processes and the design and testing of innovative solutions as well as the upscaling and diffusion of new successful products, processes and organizational forms. Finally, it identifies several common pitfalls that are important for changemakers to avoid, including an assumption of the necessity for heroic leadership, failure to include relevant actors, overly strict and detailed plans and procedures, and inability to integrate newcomers.

Abstract
This chapter looks at how Goal 17 on partnerships can be a lever of change. It discusses the partnership approach to achieving the SDGs and unravels the key functions of networks and partnerships, such as knowledge sharing, coordination, and collaborative governance. It carefully explains why we need to shift the focus of the global debate from collaborative governance to the cocreation of public value outcomes. It then provides a schematic account of the different steps in the process of cocreating outcomes, which include initiation, design, implementation, and evaluation. Finally, the chapter identifies the key merits of cocreation and looks its dark side straight in the eye.
