Abstract

Education of Guru Penggerak is the Government's innovation to prepare for future leadership transformation. Before becoming a leader, the teacher mobiliser is required to be the main actor in classroom learning and mobilise peers through a community of practice. Thus, they are expected to become leaders in school management and development. Candidate of Guru Penggerak, after undergoing Education and Training for 6 months covering 10 modules, will become student-centred learning leaders. The implementation of quality student-centred learning has not been optimal and equitable from one region to another. The low level of literacy and numeracy in the education report card has led the Government to launch the Merdeka Belajar Programme. The purpose of the research conducted on prospective Guru Penggerak is to determine the impact of Education of Guru Penggerak on improving learning through improving grades during education and increasing competence in self-development and learning leadership, knowing the motivation of prospective Guru Penggerak after completing education and whether literacy and numeracy materials are needed. The research method uses quantitative descriptive research using data collection techniques of interviews, documentation, questionnaires and observations, pre-test-post test scores and questionnaires on prospective Guru Penggerak. The results obtained from this study are an average increase from the pre-test score of 50.80 to the average post-test score of 64.58 or an increase of 13.77. From the questionnaire, the competence of self-development and others increased from 76.82% to 87.35%. For learning leadership competence there was an increase from 73.03% to 85.04%

Abstract

Durian seed flour can be used for the manufacture of food products such as sticks and steamed sponges. Sticks and steamed sponge cake are foods that many people like from children to adults.  Durian seed flour is rich in minerals including magnesium, potassium, calcium and phosphorus. This study aims to determine the content of magnesium, potassium, calcium and phosphorus in food products from durian seed flour using Atomic Absorption Spectrophotometer (SSA) and UV-Vis Spectrophotometry.   The results showed that the magnesium content in the sticks of durian seed flour with formulation 1 (0% durian seed flour) amounted to 84,053 mg/kg, formulation 2 (50% durian seed flour) amounted to 145,213 mg/kg and formulation 3 (100% durian seed flour) amounted to 142,313 mg/kg.  Potassium content on sticks from durian seed flour with formulation 1 (0% durian seed flour) of 1,186 mg/kg, formulation 2 (50% durian seed flour) of 1,863 mg / kg and formulation 3 (100% durian seed flour) of 1,693 mg/kg.  The calcium content in steamed sponge from durian seed flour with formulation 1 (0% durian seed flour) of 30.37 mg/kg, formulation 2 (50% durian seed flour) of 37.84 mg/kg and formulation 3 (100% durian seed flour) of 35.84 mg /kg. While the phosphorus content n steamed sponge from durian seed flour with formulation 1 (0% durian seed flour) of 17.1 mg/kg, formulation 2 (50% durian seed flour) of 27.1 mg/kg and formulation 3 (100% durian seed flour) of 24.3 mg/kg.

Abstract

The mean values of MAN 2 Palu students on the topic of reaction rates in the last three years are low. The cause of low learning outcomes is learning that has not paid attention to students’ average learning styles. The learning model used in this study is a guided inquiry model with an active dimensional learning style. The research sample selection technique was purposive sampling by taking into account the average student learning outcomes. The research samples were 27 students in class XI MIA6 as an experimental class, learning with the model and class XI MIA4 with 27 students as a class, learning with a guided inquiry control model. The stages of the research were identifying students' learning styles in the experimental class, applying the ITG-Dia model in chemistry learning by observing attitudes and skills activities and ending with giving an evaluation. The results of the learning style assistance were obtained by 8 students with an active dimension style which were then distributed to each group before learning was carried out. The results of the experimental class research obtained an average altitude of 84.26 (very good); skills of 79.42 (good); learning outcomes of 83; n-gain of 0.78 (high). Control class observations obtained an average altitude of 85.93 (very good); skills 79,79,56 (good); learning outcomes 60.78; n-gain 0.50 (medium). The results of the t-test statistical analysis obtained t 13.12 and t 1.67. The results of the statistical analysis showed that there were significant differences in student learning in the experimental class and the control class. Based on statistical analysis, it can be concluded that the application of the active-reflective dimensional model affects increases students' chemistry learning outcomes.
