Engineering education is an important part of preparing quality graduates for the challenges of the Covid-19 and post-pandemic conditions, and electronics engineering education is no exception. Blended learning-based projects as an alternative to innovative learning at this time. This study aims to explore and explain the application of blended learning-based projects in electronics engineering education courses. The research method used is a project-based product design and development carried out by blended learning. We conduct our project activities in higher education special students from Electronic Engineering Education that take part in the learning of this project. Students who participate are only limited to small groups to avoid the impact of the Covid-19 pandemic, in 1 small group consisting of 3-5 people and there is 1 group leader who manages the work, while other members are supportive and help complete joint projects. The results of this study show the ability of students to work by implementing project-based learning in producing products, namely Exhaust Fan products based on Electrostatic Precipitator (ESP) as a form of a mini prototype that can be used for small household scale industries. The ability of students to work on product manufacturing by applying the principles of project-based learning in the category already has the ability to, skilled and thoroughly working on the project that was planned until it succeeded in becoming a product prototype which was carried out in project-based blended learning.

Pencemaran udara merupakan masalah yang cukup serius saat ini. Karena udara merupakan aspek yang sangat penting bagi kehidupan makhluk hidup di bumi. Banyak sumber pencemaran udara saat ini, salah satunya adalah pencemaran yang disebabkan oleh asap sisa pembakaran pabrik atau industri. Untuk meminimalisir polusi udara yang ditimbulkan oleh industri maka dibuatlah sistem penyaring asap keluaran cerobong pada industri. Sistem penyaring ini menggunakan prinsip electrostatic precipitator(ESP). Prinsip ini memanfaatkan efek korona yang diciptakan oleh listrik yang memiliki tegangan tinggi. Korona listrik terjadi ketika ada dua kabel paralel yang memiliki penampang kecil yang diberi tegangan bolak-balik. Hal ini disebabkan oleh kabel yang saling bersilangan, yang menciptakan medan listrik yang dapat menimbulkan percikan api. Hilangnya elektron dari molekul udara menghasilkan medan listrik di sekitar mereka.Medan ini dapat menyebabkan elektron bebas bergerak lebih cepat dan terjadi tumbukan dengan molekul lain.Hal inilah yang dimanfaatkan oleh ESP untuk membantu proses particle charging.
