Abstract

Air adalah bagian penting dalam kehidupan manusia, begitu juga dengan perairan. Tetapi seiring bertambahnya penduduk, sampah yang mencemari perairan semakin meningkat, terutama sampah plastik yang sulit terurai. Dalam proses degradasi, plastik menjadi potongan kecil yang disebut mikroplastik. Potongan ini berukuran kurang dari 5 mm dan tersebar dalam perairan. Pencemaran mikroplastik tentu berbahaya bagi kehidupan organisme di sekitarnya. Dari permasalahan tersebut, penelitian ini bertujuan untuk mengembangkan filter mikroplastik dengan metode rapid sand filtration dan granular activated carbon dengan desain yang menyerupai struktur tubuh paus biru. Filter diujikan pada air Sungai Code, Sungai Winongo, Sungai Gajahwong, dan Sungai Manunggal. Hasil penelitian menunjukkan bahwa persentase tertinggi penurunan konsentrasi mikroplastik pada filter sebesar 88,5% dan persentase rata rata 75,4% untuk filtrasi dengan pembilasan dan 71,7% untuk filtrasi tanpa pembilasan. Filter memiliki debit filtrasi rata rata sebesar 6x103 m3/s. Hasil penelitian dan pengembangan pada filter cukup efektif untuk diimplementasikan ke sungai yang tercemar.

Abstract

This research is experimental. This research was conducted at SMK Negeri 2 Kebumen in the 2022/2023 academic year. The sample selection in this study was class XII TP 3 as much as 35 as the control class and class XII TP 4 as the experimental class with a total sample of 35. The experimental class was treated in the learning process using E-Module learning media, and the control class was given treatment in the learning process with conventional methods. The design used in this study was the Pretest and Post Test Control Group Design. The research instrument is in the form of learning outcomes. To test the hypothesis using the paired sample t-test. The analysis was conducted descriptively. The results of this study indicate that the effect of the E-Module on student learning achievement shows a significant increase compared to learning without the E-Module. the result of the sig value is less than (\alpha) = 0.05, then H0 is rejected and Ha is accepted which shows that there is an effect of the E-Module on student achievement.
