Abstract

Air permukaan yang ada di bumi ini tidak selamanya dapat dimanfaatkan menjadi air bersih, karena kondisinya masih jauh dari standar kualitas baku mutu air. Air permukaan tersebut masih banyak mengandung zat padat tersuspensi maupun koloid. Pada pengolahan air bersih, proses yang dapat meremoval zat-zat padat tersebut adalah koagulasi dan flokulasi. Pada proses koagulasi dan flokulasi dilakukan penambahan koagulan yang berfungsi untuk membentuk flok yang kemudian diendapkan. Gravel Bed Flocculator adalah salah satu alat flokulasi yang menggunakan pengadukan secara hidrolis. Pengadukan hidrolis adalah pengadukan dengan memanfaatkan gerakan air sebagai energi pengaduk seperti energi gesek media butiran. Keuntungan dari gravel bed flocculator adalah mampu mengendapkan flok dalam waktu singkat berkisar 3-5 menit yang setara dengan waktu 15 menit uji jar test atau sekitar 25 menit waktu proses flokulasi yang berlangsung secara konvensional. Pada penelitian ini menggunakan 2 variabel yaitu variasi jenis koagulan (Al2(SO4)3 dan FeCl3) dan variasi waktu tinggal (waktu tinggal 3 menit dan waktu tinggal 4 menit) dengan jenis aliran pada penelitian ini adalah aliran upflow. Hasil penelitian menunjukan efektifitas removal tertinggi pada koagulan Al2(SO4)3 terhadap parameter kekeruhan terjadi pada waktu tinggal 4 menit yaitu sebesar 93,28% sedangkan untuk koagulan FeCl3 terjadi pada waktu tinggal 4 menit juga yaitu sebesar 93,50% dan efektifitas removal tertinggi pada koagulan Al2(SO4)3 terhadap parameter coliform terjadi pada waktu tinggal 4 menit yaitu sebesar 99,74% sedangakan untuk koagulan FeCl3 terjadi pada waktu tinggal 4 menit juga yaitu sebesar 99,99%.

Abstract

Multimodal e-modules develop students' abilities in understanding a variety of multimodal texts which encourage intellectual quality and broader learning experiences. Multimodal-based learning can be integrated with local wisdom as an effort to preserve cultural values. The aim of the research is to determine the need for a multimodal e-module based on Madurese local wisdom for writing short story texts. This research is aqualitative descriptive research oriented towards the development of a product. The data collection technique was carried out through a questionnaire distributed to Indonesian language teachers and also to students at two high schools in Pamekasan Regency via Google Forms. Data were analyzed using descriptive analysis and the percentage of the total number of answers given was divided by the total number of respondents multiplied by 100%. The results of this research show that learning to write short story texts has never been carried out using e-modules, the use of multimodal teaching materials has never been done, and the short story texts presented in learning have not been based on local Madurese wisdom. Based on these results, it can be concluded that the development of a multimodal e-module based on local Madurese wisdom is really needed by students so it needs to be developed to support the short story writing skills of class XI high school students.
