EXPLORATION OF SOCIAL JUSTICE ORIENTED MATHEMATICAL PROBLEM MODELING RELATED TO THE SINGARAJA-MENGWITANI SHORTCUT PROJECT

In connection with the Singaraja-Mengwitani Sortcut Project, many real life problems can be raised whose substance is related to mathematical concepts. The aim of this research is to describe the social justice oriented mathematical modeling related to the Singaraja-Mengwitani Shortcut Project for prospective elementary school teachers. The type of research used is qualitative with a case study design. The subjects of this research are Elementary School Teacher Education (PGSD) Universitas Pendidikan Ganesha students who in 2023 will carry out Field Experience Practices. The number of research subjects was determined by 6 people consisting of 3 men and 3 women. The instruments used were tests and interview guides, while data collection techniques used tests and interviews. The data analysis used is descriptive qualitative. This research shows that: (1) the ability to construct and simplify in modelling is categorized as very good, in mathematization it is categorized as fair, in interpreting and validating it is categorized as very poor, while in exposing it is categorized as not good; (2) judging from sex differences, the ability to construct and simplify is the same in the very good category, the ability to interpret and validate is the same in the very poor category, while the ability in mathematization is different, men are classified as good and women are categorized as enough; and (3) the logical reasons or additional information provided are very realistic and relate to real life and are oriented towards social justice. For example, compensation for land acquisition profits given takes into consideration the trees or buildings on the acquired land. Shortcut project profits do not only consider financial profits, but also non-material assets and wider impacts.
