Abstract

This study aims to improve students' learning outcomes in the material of appreciating historical heritage through the application of the Numbered Head Together (NHT) cooperative learning model at MIS Al-Hidayah Namorambe. The NHT learning model is one of the cooperative learning strategies that involves active participation of students in groups. In this process, each student is given a number and takes turns answering questions asked by the teacher. This approach aims to improve students' understanding, participation, and learning outcomes.The research method used is classroom action research (CAR) which is implemented in two cycles. Each cycle consists of planning, action implementation, observation, and reflection stages. Data were collected through learning outcome tests and observation of student activities. The results of the study showed a significant increase in student learning outcomes after the implementation of the NHT model. In addition, the implementation of this model also increases learning motivation and cooperation between students in groups. The conclusion of this study is that the NHT type cooperative learning model is effective in improving student learning outcomes in the material of appreciating historical relics. Therefore, this model is recommended to be used as an alternative learning strategy in history subjects in elementary schools.

Abstract

Sampah plastik merupakan salah satu permasalahan lingkungan yang terus mengalami peningkatan seiring dengan tingginya penggunaan plastik sekali pakai dalam kehidupan sehari-hari. Plastik memiliki sifat sulit terurai sehingga dapat menimbulkan penumpukan sampah yang menyebabkan pencemaran lingkungan, merusak ekosistem, serta berdampak negatif terhadap kesehatan manusia. Kurangnya kesadaran dan pengetahuan masyarakat, khususnya peserta didik, menjadi salah satu faktor yang memperparah permasalahan sampah plastik. Oleh karena itu, diperlukan upaya edukatif sejak usia dini untuk menanamkan kepedulian terhadap lingkungan. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pengetahuan dan kesadaran siswa mengenai dampak sampah plastik terhadap lingkungan melalui kegiatan sosialisasi di SDN 200105 Padangsidimpuan. Metode pelaksanaan kegiatan meliputi penyampaian materi secara langsung, diskusi interaktif, serta pemberian contoh perilaku hidup bersih dan peduli lingkungan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman siswa mengenai bahaya sampah plastik serta pentingnya menjaga kebersihan lingkungan sekolah. Kegiatan ini diharapkan dapat menumbuhkan sikap peduli lingkungan dan membentuk kebiasaan positif dalam pengelolaan sampah sejak usia dini.
