Permasalahan yang umum ditemui pada daerah pesisir pantai yaitu buruknya sanitasi seperti minimnya aksesair bersih yang memenuhi syarat, dalam hal ini air tawar. Oleh karena itu perlu diadakan pengolahan terhadap air payau untuk memperbaiki kualitas air khususnya dalam hal salinitas. Jenis penelitian ini adalah eksperimen, tujuan penelitian yaitu untuk mengetahui kemampuan karbon aktif ampas tebu dalam menurunkan kadar salinitas pada air payau dosisi 400 gram karbon aktif dan variasi waktu kontak 30 menit, 90 menit dan 150 menit dengan metode adsorpsi pada sumur gali sebelum dan sesudah pengolahan. Hasil penelitian menunjukkan bahwa kadar salinitas setelah perlakuan dengan metode adsorpsi menggunakan karbon aktif ampas tebu yakini, kadar salinitas pada sampel awal yaitu 3,33 ppt setalah pengolahan dengan waktu kontak 30 menit kadar salinitas turun menjadi 2,19 ppt dengan persentase 34,22%, pada waktu kontak 90 menit turun menjadi 2,03 ppt dengan persentase 39,15%, pada waktu kontak 150 menit turun menjadi 1,33 ppt dengan persentase 59,95%. Berdasarkan pembahasan maka dapat disimpulkan bahwa karbon aktif ampas tebu mampu menurunkan kadar salinitas pada air payau. Saran untuk peneliti selanjutnya yaitu yang menggunakan media karbon aktif ampas tebu untuk menambah waktu kontak antara media karbon aktif dengan sampel air payau
Thematic learning with the main content of science is not learning that only memorizes concepts. However, there needs to be learning where students experience and find out for themselves. The learning in question is practicum-based. This research aims to examine the effect of developing a practical guidebook on students' interests and critical thinking skills. The research method used is the type of research and development or R&D with a 4D procedural model. The sample in this study was 137 students in class IV, with a sampling technique of purposive sampling. Researchers used a questionnaire as a data collection instrument. The questionnaire used consisted of a student interest questionnaire and critical thinking. Data analysis used descriptive statistics and regression tests. Descriptive statistics are used to analyze data by describing or describing the data that has been collected. The results of this study are that students' interest in learning and students' critical thinking skills are categorized as good. The results of the regression test revealed that the implementation of the thematic practicum guidebook theme 2 affected students' interest and critical thinking skills. The implications of the research & development of the thematic practicum guidebook theme 2 in class IV learning are practical guide material. Therefore, it is essential to use a practicum manual in the learning process by both teachers and students to increase and develop students' interests and critical thinking skills.
