A self-healing epoxy-amine thermoset based on the compatible functionalization of the thermoset and encapsulated healing agent has been successfully developed. Healing of the thermoset resulted from the reaction of furans in the thermoset and multimaleimides (MMIs) in the healing agent solution. The healing agent, MMI dissolved in phenyl acetate, was encapsulated using a urea-formaldehyde encapsulation method. Autonomic healing of the thermoset was achieved by incorporating microcapsules filled with the healing agent solution within a furan-functionalized epoxy-amine thermoset. The resulting self-healing thermoset recovered 71% of its initial load after fracture.

The healing of a furan-functional epoxy coating using bismaleimide (BMI) solutions is demo nstrated. Corrosion studies of scratched coated carbon steel show that solution healing of damaged coatings inhibits corrosion. The healing relies on (i) the diffusion of solution components into the polymer, causing the system to swell, thus bringing crack surfaces into contact, and (ii) Diels-Alder adduct formation between furan moieties of the polymer network and the maleimide, resulting in covalent bonding across the crack interface. For the system investigated, crack healing is reaction-limited for small crack widths. The results provide a guideline for the design and implementation of self-healing systems based on BMI solution encapsulation.

Education is a mandatory requirement that must be possessed by every human being, until whenever education is needed by every individual human to fulfill the needs and perfect themselves as people who are knowledgeable, moral, and useful in a national development. This type of research uses quantitative descriptive research. Ali Maksum (2012: 68) descriptive research is research that is conducted to describe the real occurrence of circumstances. the results of the study obtained the implementation of the 2013 curriculum in physical education in the Junior High School in the Kertosono Subdistrict. the "low" category is 5 students or 22.8%; "medium" category as many as 8 students or 36.3%; the "high" category is 4 students or 18.2%; and the category of "very high" by 2 students or by 9.1%
