Context: Human Epidermal Growth Factor (hEGF) is a potential therapeutic protein that has been widely used as a healing agent for various chronic wounds. It induces the proliferation and metabolism of epithelial cells, regenerates skin cells, and validates skin elasticity. In the previous study, recombinant hEGF (rhEGF) had been successfully expressed extracellularly in Escherichia coli (E. coli) BL21 (DE3) using pectate lyase B (PelB) signal peptide. The previous study has shown that the medium concentration and the induction time influenced the production of rhEGF. Aims: Therefore, this study was conducted to optimize the induction time and medium concentration for rhEGF extracellular secretion then followed by scale-up production. Settings and Design: This experiment was carried out using E. coli BL21 (DE3) which contains pD881 plasmid that carries hEGF and PelB gene. Optimization design of induction time and medium concentration were obtained using Central Composite Design (CCD). Methods and Material: The method of study started by the rejuvenation of E. coli culture, extracellular secretion, and optimization in the flask scale then followed by scaled-up production with high-cell density culture in the fermenter. Statistical analysis used: The optimization was carried out using Response Surface Methodology (RSM) and multi regression analysis. Results: This work showed that the multiplication of 1.5-fold medium concentration with induction time 3h after the culture started gave the best result among another condition in this study. Additionally, the rhEGF production in the fermenter scale was identified by SDS-PAGE Tricine and quantified by ELISA, which showed 122.40 μg of the rhEGF per milliliter medium. Conclusions: In respect of the result, we conclude that the optimized condition of extracellular secretion was successfully obtained, and gives higher result before the previous study.

Nowadays mathematics is still considered difficult, so it needs more attention because mathematics is the basis of other sciences. One of the factors that influence Mathematics Learning Outcomes (MLO) is Self-Regulated Learning (SRL). SRL plays a role in the process of planning and managing student academic assignments. Interest in Learning Mathematics (ILM) also has an important role in learning mathematics. The purpose of this study was to determine the effect of each SRL aspect on mathematics learning outcomes and to determine the effect of SRL on MLO in terms of the student's ILM level. The author uses mixed methods with a sequential exploratory research design that begins with a qualitative phase using descriptive qualitative research and then a quantitative phase using a correlation test. SRL aspects include task analysis, self-motivated belief, self-control, monitoring, self-consideration, and self-reaction. The results of this study are that there is an influence between SRL aspects on MLO, except for the task analysis aspect. SRL with MLO also does not have a significant effect when viewed from the ILM level.
