Abstract

Schools are required to implement environmentally conscious awareness as a reference for the general public. This realization is greatly influenced by the leadership of the principal. This study aims to examine the effective leadership of the principal in providing space for teacher innovation in developing environmentally conscious schools. This study uses the expos facto method, in several Muhammadiyah schools in LEUWILIANG, LEUWISADENG, AND PAMIJAHAN Districts. In this study, it was found that assertive, effective principal leadership provides space for innovation for teachers to develop environmentally conscious schools compared to schools led by principals with a dominating leadership style. Thus, the researcher concluded that developing environmentally conscious schools requires assertive principal leadership, because the development of environmentally conscious schools greatly requires innovation from all parties within the school environment

Abstract

Hemorrhage is a leading cause of rapid death, particularly postpartum hemorrhage. One of the triggers is perineal wounds which, if not properly treated, can lead to complications such as bacterial infections. The people of Lalonggasumeeto, Southeast Sulawesi, empirically use Wilalondahi (Archidendron lucyi) bark to treat wounds. However, scientific evidence regarding its anti-inflammatory and wound-healing activities remains unavailable. This study evaluates the in vivo effect of Wilalondahi bark extract gel on the wound healing process in mice (Mus musculus). Methods included phytochemical screening, total flavonoid measurement, and observation of incision wounds. Parameters measured were healing duration, erythema, edema, and crusting. Results showed that the 96% ethanol extract of Wilalondahi bark contains a total flavonoid content of 65,67 mg QE/g. The extract demonstrated significant wound healing and anti-inflammatory activity (p < 0,05). The 15% concentration (P3) showed the most effective results, with wounds completely healed and crusts detached by day 9. Furthermore, the extract treatment was proven to effectively reduce inflammatory symptoms such as erythema and edema, showing comparable effectiveness to the positive control.
