Abstract

This study sought to explore Indonesian university students' perceptions, problems, and suggestions of the application of blended learning in their EFL courses. A questionnaire consisting of 6 categories (benefits of online learning, benefits of face-to-face learning, learning assessment, problems in blended learning, suggestions for quality improvement of blended learning, and open-ended questions) was used as the research instrument. The collected data were analyzed descriptively and qualitatively. The results showed that most of the students perceived positively both the online and face-to-face modes used in their blended EFL courses, although they tended to have negative views on certain online technical aspects. Internet connectivity was the main problem and the solution of all technical problems was the main suggestion reported by the students. As this research was conducted only with students from one study program, the results should not be generalized and future research is suggested to be more focused on the comparison of students’ preferences for other blended course formats and relate them to students’ EFL achievement.

Abstract

Hidroponik khususnya telah menjadi metode mutakhir untuk meningkatkan produktivitas dan efisiensi pertanian melalui pemanfaatan teknologi. Pertumbuhan tanaman sangat dipengaruhi oleh parameter seperti pH dan Total Dissolved Solids (TDS). Menggunakan mikrokontroler ESP32 dan aplikasi Blynk, penelitian ini menciptakan sistem pemberian nutrisi otomatis berdasarkan kadar TDS dan pemantauan pH berbasis Internet of Things (IoT). Sistem ini secara otomatis menjaga kadar TDS dengan mengendalikan pompa peristaltik dan pompa air bersih menggunakan modul relai. pH dipantau, dan ketika terjadi variasi, pesan peringatan akan diberikan. Google Sheets merekam data secara real-time, yang kemudian ditampilkan di aplikasi Blynk. Berdasarkan hasil pengujian, sistem berhasil menjaga TDS dalam rentang yang diinginkan, meskipun pH sebagian besar tetap konstan dan perlu disesuaikan secara manual. Metode ini meningkatkan efektivitas pemantauan dan pengendalian dalam pertanian hidroponik skala kecil sekaligus mengurangi kebutuhan akan intervensi manual.
