PENGEMBANGAN VIDEO PEMBELAJARAN BERBASIS PROBLEM BASED LEARNING UNTUK MATERI  PERPINDAHAN PANAS KONVEKSI PAKSA PADA WIRE AND TUBE HEAT EXCHANGER

DEVELOPMENT OF PROBLEM-BASED LEARNING VIDEOS BASE D LEARNING FOR FORCED CONVECTION HEAT TRANSFER MATERIAL ON WIRE AND TUBE HEAT EXCHANGER

Perpindahan panas merupakan salah satu keilmuan nya harus dimiliki oleh semua mahasiswa jurusan teknik mesin. Namun berdasarkan observasi mahasiswa mengalami kesulitan dalam mengikuti pembelajaran. Hal itu dikarenakan karena tidak adanya media pembelajaran yang dapat menvisualisasi dari materi konveksi paksa pada wire and tube heat exchanger yang dijelaskan, sehingga menyulitkan siswa untuk memahami materi secara utuh.

Berdasarkan permasalahan tersebut peneliti mengembangkan video pembelajaran. Model pengembangan yang digunakan adalah pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation).

Dalam proses pengembangan dilakukan validasi video pembelajaran yang meliputi dari tiga aspek mulai dari aspek materi, media dan Bahasa. Aspek materi mendapatkan nilai 83% yang masuk dalam kategori sangat layak. Aspek media juga masuk dalam kategori sangat layak dengan nilai mencapai 90%. Aspek bahasa nilai validitas mencapai 93% dengan kategori sangat layak. Hasil respon mahasiswa untuk video pembelajaran didapatkan nilai sebesar 91% dimana nilai tersebut masuk dalam kriteria sangat baik. Nilai t hitung > t tabel yang mana 9,546488376 > 2,079613845. Dari hasil tersebut bahwa penerapan video pembelajaran efektif dalam meningkatkan hasil belajar. N-Gain skor sebesar 0.57 atau 57%, sehingga tingkat efektivitas video pembelajaran masuk pada kategori “Sedang” dan “cukup efektif”. Dapat disimpulkan bahwa video pembelajaran berbasis problem based-learning untuk materi perpindahan panas konveksi paksa pada wire and tube heat exchanger valid untuk di terapkan dalam pembelajaran, efektif dalam meningkatkan hasil belajar mahasiswa, dan mendapatkan respon positif dari mahasiswa.

    Heat transfer is one of the sciences that must be owned by all students majoring in mechanical engineering. However, based on observations, students have difficulty in following learning. This is because there is no learning media that can visualize the forced convection material on the wire and tube heat exchanger described, making it difficult for students to understand the material as a whole.

    Based on these problems, researchers developed learning videos. The development model used is ADDIE (Analysis, Design, Development, Implementation, Evaluation).

    In the development process, validation of learning videos is carried out which includes three aspects ranging from aspects of material, media and language. Aspect material gets a value of 83% which falls into the very decent category.  Media aspect validity are also included in the very decent category with a value of up to 90%. Language aspect validity value reaches 93% with a very decent category.  The results of student responses to learning videos obtained a score of 91% where the score was included in the very good criteria. The value of t is calculated > t table where 9.546488376 > 2.079613845. From these results that the application of learning videos is effective in improving learning outcomes. N-Gain score of 0.57 or 57%, so the effectiveness level of learning videos is included in the "Medium" and "moderately effective" categories. It can be concluded that problem-based learning videos for forced convection heat transfer material on wire and tube heat exchangers are valid for application in learning, effective in improving student learning outcomes, and getting positive responses from students.
