Abstract

Penelitian pengembangan ini bertujuan menghasilkan perangkat prak-tikum berorientasi lingkungan pada mata pelajaran IPA SMP sesuai kurikulum 2013. Produk dikem-bangkan mengacu pada model pengembangan Borg & Gall yang dibagi menjadi tiga tahap, yaitu: studi pendahuluan, pengembangan, dan uji produk. Data yang dikumpulkan berupa data kualitatif dan kuantitatif menggunakan angket. Subjek penelitian adalah ahli, guru, dan siswa. Guru dan siswa yang dijadikan sampel pada uji coba adalah guru IPA dan siswa SMPN 2 Singaraja. Hasil pengujian menunjukkan bahwa perangkat praktikum yang dikembangkan termasuk kriteria valid. Skor rata-rata uji keterbacaan pada uji coba terbatas termasuk kriteria sangat valid. Pada uji coba terbatas dan luas, hampir seluruh siswa memberi respon posistif. Guru memberikan respon positif terhadap perangkat praktikum berorientasi lingkungan, baik dari segi kemudahan mempersiapkan maupun mengimple-mentasikannya. Dapat disimpulkan bahwa perangkat praktikum berorientasi lingkungan yang dikem-bangkan sudah memenuhi kriteria relevan dan mudah digunakan. Kata-kata Kunci: penelitian pengembangan, perangkat praktikum, praktikum berbasis lingkungan

Abstract

Preventing accidents in chemistry laboratories is a critical concern, as laboratory activities involve chemical hazards, equipment risks, and procedural errors. One of the main contributing factors to laboratory accidents is inadequate student competence during practical activities. However, systematic predictors for assessing practicum competence are still rarely implemented. This study aims to examine the effectiveness of Miller’s Pyramid as a predictor of students’ practicum competence in preventing work-related accidents in chemistry laboratories. The research employed a descriptive evaluative design. The participants consisted of students from the Chemistry Department who were involved in laboratory practicums. The object of the study was students’ practicum competence based on the four levels of Miller’s Pyramid: knows, knows how, shows, and does. Data were collected through written tests, interviews, and direct observations using structured assessment rubrics. The collected data were analyzed descriptively and presented in percentage form. Student competence was categorized as good when at least 70% of the indicators at each Miller’s Pyramid level were achieved. The results showed that students’ competence at all levels of Miller’s Pyramid met the established criteria, indicating good overall practicum competence. Furthermore, the findings demonstrate that Miller’s Pyramid can effectively function as a predictor of students’ practicum competence related to laboratory safety. In conclusion, the application of Miller’s Pyramid provides a comprehensive framework for assessing and improving student competence, thereby contributing to the prevention of work accidents in chemistry laboratories
