Abstract

Waste is one of the major problems in Indonesia. Waste continues to increase every year. The two major contributors of waste are plastic and metal processed waste. The two kinds of waste are undegradable. Therefore, the most appropriate solution in handling these kinds of waste is to recycling or converting. One of the efforts that can be made to waste aluminum is beverage packaging, namely by turning it into alum. Alum is commonly used as a water purifier, especially water containing calcium and magnesium metals which are often called hard water. The method used is gravimetric methods. Based on research data, alum can absorb calcium metal with an effectiveness level of 42.25% and magnesium metal with an effectiveness level of 64.12%. Keywords: alum, calcium metal, magnesium metal, gravimetric methods

Abstract

Based on the Decree of the Minister of Education and Culture of the Republic of Indonesia No. 1177/M/2020 concerning the Penggerak School Program, the determination of the educational unit as the implementer of the Penggerak School Program is carried out by selecting the Head of the Education Unit who has learning leadership, learning that supports students and a willingness to learn that represents diversity throughout Indonesia (differentiated learning). The presence of the Penggerak School Program began with an independent curriculum development program which started from the implementation of the 2013 curriculum which was considered too rigid, the material was too dense and learning loss was caused by the impact of online learning during the Covid-19. The method used in research is libarary research methods. In general, this research describes the results of the penggerak school program carried out at the educational unit level, so that it can encourage the transformation process of educational units in order to increase student learning outcomes character in order to realize Pancasila students. Penggerak School Program has several advantages, namely being a school that can provide guidance to other schools (model school), getting assistance from expert trainers, accelerating school digitalization & improving the quality of school principals and teachers. Schools that take part in the Penggerak School Program will be expected to have output as a pioneer force in the transition to the independent curriculum.
