Abstract

The teaching and learning process is based on a quality education system, one of the stages to achieve the above is by creating a comfortable school atmosphere, by implementing Green School. But in practice there are still many schools that have not implemented greening programs in their schools even though the government has socialized the importance of reforestation in schools from an early age, in order to get cool air and a good environment. In the Petungroto hamlet there is only one Tunas Bangsa ECD and has not implemented greening with various types of plants, these plants are placed in the school environment to provide comfort during the teaching and learning process and introduce plants to children from an early age. For this reason, there is a need for assistance in managing Green School-based PAUD in Petungroto Hamlet, Babadan Village, Ngajum District, Malang Regency. In addition to realizing greening in the PAUD environment, activation assistance for waste bank management is carried out so that it can be guaranteed to improve people's lives from various health and economic aspects. The method used in KKN-PPM activities is (1) Implementation of Green School by utilizing existing resources wisely, (2) Management of Waste Bank from the garbage collection process, sorting the recording and sale of waste bank results. The target and outcome to be achieved from the KKN-PPM activities is to make PAUD Tunas Bangsa as a Green School, introducing the types and benefits of plants to children. Village officials and the community can understand the importance of reforestation and the benefits of the Waste Bank for the environment in Petungroto Hamlet, Babadan Village, Kec. Ngajum.

Abstract

Untuk mengukur berpikir kritis, peneliti merumuskan “bagaimanakah proses berpikir kritis mahasiswa melalui perkuliahan penyelesaian masalah program linier?”. Penelitian ini bertujuan untuk memaparkan terjadinya proses berpikir kritis mahasiswa melalui pembelajaran penyelesaian masalah program linier. Proses berpikir kritis memiliki 4 indikator antara lain: Pertama, identifikasi unsur-unsur yang diketahui dan ditanyakan, Kedua, penerapan strategi untuk penyelesaian masalah, Ketiga, perumusan masalah ke bentuk matematis, Keempat, interpretasi. Hasil penelitian ini diperoleh dari observasi dan tes akhir penelitian. Hasil observasi siklus I pertemuan I aktivitas mahasiswa berdasarkan pengamatan PI sebesar 81% sehingga dalam kriteria baik. Sedangkan pengamatan P2 sebesar 86% sehingga dalam kriteria baik, maka dapat disimpulkan aktivitas mahasiswa pada pertemuan I dalam kriteria baik. Pada siklus II diperoleh untuk pertemuan I aktivitas mahasiswa berdasarkan pengamatan PI sebesar 85% sehingga dalam kriteria baik. Sedangkan pengamatan P2 sebesar 87% sehingga dalam kriteria baik, maka dapat disimpulkan aktivitas mahasiswa pada pertemuan I dalam kriteria baik. Berdasarkan hasil tes akhir penelitian terungkap persentase ketuntasan klasikal (TB) sebesar 91%. Kata kunci: proses berpikir kritis, penyelesaian masalah, program linier

Abstract

This study aimed to develop and test the feasibility of a diagnostic instrument for assessing students' critical thinking skills on socio-scientific issues (SSI) in physics education with the topic of global warming. This objective is motivated by the lack of valid, reliable, and contextually appropriate assessment instruments based on Socio-Scientific Issues (SSI) in physics education at the secondary school level, amid the low critical thinking competencies of Indonesian students as indicated by the 2018 PISA survey, and the need for an SSI approach as an effective strategy. The research method employs a research and development (R&D) design using the ADDIE model. The instrument was developed in the form of 20 essay questions based on SSI contexts and its validity was reviewed by experts and tested on 75 students from two high schools in rural and urban areas. Data were analyzed using Rasch modeling with the assistance of WINSTEPS software. Expert validation results showed that the instrument was categorized as “Highly Suitable.” Rasch model analysis confirmed the instrument's unidimensionality (raw variance explained by observed measures: 30.9%). The analysis results showed that all items were deemed fit (Outfit MNSQ: 0.78–1.28; ZSTD:–1.51 to 1.81; and PTMEA Corr: 0.26–0.68). The instrument's reliability is high, with a Cronbach's alpha of 0.81, person reliability of 0.80, and item reliability of 0.91, using a structurally valid rating scale. However, significant DIF based on gender and region was found, indicating the need for further revision to ensure measurement fairness. This instrument is deemed valid and reliable for use as a diagnostic tool for critical thinking skills in SSI-based physics learning.
