Abstract

Observasi dilakukan melalui wawancara dengan guru fisika di SMA Negeri 1 Wundulako bahwa beberapa siswa masih belum terbiasa dengan soal pemecahan masalah, sehingga mengakibatkan kesulitan dalam menganalisis masalah yang disajikan oleh guru. Penelitian ini bertujuan untuk menilai sejauh mana keterampilan pemecahan masalah fisika siswa melalui penerapan model PBL dengan pendekatan kontekstual, mengevaluasi efektivitas PBL dalam meningkatkan keterampilan ini, dan memeriksa hubungan dua arah antara kedua variabel. Penelitian ini merupakan penelitian eksperimental dengan menggunakan desain pra-eksperimental. Kami memberikan pretest dan posttest kepada subjek untuk mengumpulkan data. Temuan pretest penelitian menghasilkan skor rata-rata 57,096, sedangkan hasil posttest menunjukkan rata-rata 77,096, yang mengarah pada kesimpulan bahwa penerapan PBL menggunakan pendekatan kontekstual secara efektif meningkatkan keterampilan pemecahan masalah fisika. Akhirnya, melalui pengujian hipotesis dengan menggunakan metode uji-t, nilai-p ditemukan kurang dari 0,05, yang menunjukkan signifikansi statistik; Oleh karena itu, kami menolak hipotesis nol H0 dan menerima hipotesis alternatif H1 yang menyatakan pentingnya penerapan model pembelajaran ini dalam konteks kelas untuk mengajarkan kurikulum Gelombang Berjalan dan Gelombang Stasioner.

Abstract

As the main water source for the surrounding environment, the Kolohipo River is very important. The river, a freshwater ecosystem, provides water for local industries, agriculture, and daily needs. However, the water quality of the Kolohipo River has declined drastically due to increasing human activities including intensive agriculture, domestic waste disposal, and deforestation throughout the river basin. Public health, environmental sustainability, and agricultural yields may be compromised by this decline in water quality. By monitoring physical, chemical, and biological parameters such as pH, dissolved oxygen, BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and heavy metal concentrations, this study attempts to assess the water quality of the Kolohipo River. heavy metals. This study also assesses the relationship between local water quality decline and human activities. The findings of this study are expected to assist initiatives to protect the river as an important resource for the Kolohipo community's way of life and offer suggestions to the community and authorities to manage and resolve water pollution issues. Kolohipo community.
