Abstract

Penelitian ini dilatarbelakangi pentingnya pemahaman matematis terhadap konsep operasi hitung penjumlahan dan pengurangan bilangan cacah siswa sekolah dasar. Tujuan penelitian ini adalah untuk menghasilkan instrumen tes untuk mengukur kemampuan pemahaman matematis siswa kelas II SD pada materi operasi hitung bilangan cacah. Teknik analisis data dalam penelitian ini menggunakan metode penelitian Research and Development (RD) dengan menggunakan model 4D yang terdiri dari 4 tahap, yaitu (1) define (pendefinisian); (2) design (perancangan); (3) develop (pengembangan); dan (4) disseminate (penyebarluasan). Subyek dalam penelitian ini adalah siswa sekolah dasar kelas 2 yang berjumlah 27 orang. Penelitian ini bertempat di SD Negeri 2 Nagri Kaler di kabupaten Purwakarta, Indonesia. Soal tes berupa pilihan ganda dan esai dibuat dengan pertimbangan judgement expert, kemudian diuji untuk melihat validitas, reliabilitas, indeks kesukaran, dan daya pembeda. Analisis uji validitas menunjukkan 6 dari 11 item instrumen valid, dengan reliabilitas tes sangat tinggi. Dengan demikian, 6 dari 11 item soal yang dikembangan dapat digunakan untuk mengukur kemampuan pemahaman matematis materi penjumlahan dan pengurangan bilangan cacah untuk siswa kelas II SD.

Abstract

School environment health and hygiene are crucial aspects for instilling healthy living habits from an early age. However, studies indicate that the level of understanding among primary school students regarding sanitation and Clean and Healthy Lifestyle (PHBS), especially handwashing practice, remains low. This research aims to describe the impact of implementing sanitation socialization based on practical activities for students at SDN 1 Nagri Kidul Purwakarta. The activities were conducted using a structured, demonstrative, and participatory educational approach, supported by the provision of portable handwashing facilities by UPI P3K students. This method placed the demonstration of correct handwashing steps as the central focus of the activity. The results show that the practical-based approach significantly improved students' understanding and skills, proving more effective than the lecture method. Students who initially only rinsed their hands are now able to correctly practice the steps of washing hands with soap, and they realize the importance of proper sanitation facilities. Thus, this socialization activity successfully cultivated the habit of correct handwashing, enhanced students' sanitation knowledge, and instilled an understanding of the necessity of adequate facilities. The sustainability of these positive habits requires facility support, ongoing guidance, and commitment from the school.
