Abstract

Medicinal plants ant nests or simbagh utak (Hydnophytum formicarum) are found in the Bengkulu area south of Bengkulu province. Simbagh utak tubers (H. formicarum) can empirically treat headaches, bruises and aches. H. formicarum also has cytotoxic, antioxidant and antibacterial activity. The purpose of this study was to determine the antidiabetic activity of the ethanolic extract of the medicinal plant simbagh utak (H. formicarum) against alloxan-induced mice, and Phytochemical Test to determine the content of secondary metabolites contained in the extract. The extract was obtained by maceration by soaking simbagh utak powder (H. formicarum) with 96% ethanol as solvent. The solvent contained in the ethanolic extract of simbagh utak (H. formicarum) was evaporated using a rotary evaporator to obtain ethanolic extract of simbagh utak (H. formicarum). Furthermore, the ethanolic extract of simbagh utak (H. formicarum) was tested on mice that had been induced by alloxan. The results showed that after the ANOVA and T-student statistical tests were carried out, it could be stated that the tuber extract of the Simbagh Utak (H. formicarum) plant was seen to be very significant in reducing blood sugar levels of male mice (Mus musculus) that had been induced by alloxan at a dose of 0.7056 g. /kg BW, and tuber extract of H. formicarum contained flavonoid and phenolic compounds. Flavonoid and phenolic compounds can act as free radical scavengers.

Abstract

Self-efficacy is one of student’s success predictors, so it should be one of the variables to be considered in learning activities. Research on self-efficacy in pesantren (Islamic boarding school) has not been widely disclosed. Therefore, it is necessary to conduct research related to gender-based self-efficacy in pesantren. The study used an ex-post-facto non-experimental quantitative design at one of the pesantren-based SMP and MTs in Pamekasan. There are 29 males and 39 females as the participants of this study. SOSESC-P was used as research instrument. Data were analyzed using t-test. Based on the result, there is no significant difference between the self-efficacy of male and female students in pesantren, with average score of 64.12 and 64.86 respectively. This indicates that the science learning process in pesantren has succeeded in bridging the achievement of self-efficacy of male and female students, with their comprehensive learning concept in 3 dimensions, namely (1) the deep dimension of religious morality, (2) the dimensions of science and technology, and (3) dimensions of skills needed in the 21st century. The result of this study can be used as evidence in policy-making, related to science learning and self-efficacy based on gender.
