Design And Construction Of Learning Media SinauO! Using A Website Platform With Project Based Learning To Improve Website Design Competency In Website Expertise Concentration Subjects (Case Study Of Class XI DKV Students At SMKN 6 Surabaya) 

Penelitian ini bertujuan untuk merancang dan mengimplementasikan media pembelajaran SinauO! berplatform website dan untuk mengetahui perbedaan kompetensi kognitif dan psikomotorik siswa dalam desain website antara pembelajaran berplatform website dengan Project Based Learning (PJBL) dan pembelajaran konvensional pada mata pelajaran konsentrasi keahlian website.

Penelitian ini menerapkan pendekatan Research and Development dengan mengadopsi model ADDIE. Rancangan uji coba yang diterapkan adalah Quasi Eksperimental dengan format Posttest Only Control Group Design. Perancangan media pembelajaran ini menggunakan bahasa pemrograman PHP 8.2 sebagai back-end, react js sebagai front-end, framework laravel serta database MySQL. Data hasil validasi media, materi, RPP, soal, dan angket respon siswa menunjukkan tingkat kevalidan secara berturut-turut yaitu, 88%(sangat valid), 92%(sangat valid), 94%(sangat valid), 89%(sangat valid), 95%(sangat valid). Jumlah nilai  rata-rata nilai posttest kognitif kelas eksperimen lebih besar daripada kelas kontrol yaitu sebesar 78,97 > 44,64. Sementara itu rata-rata nilai posttest psikomotorik kelas ekperimen juga lebih besar daripada kelas kontrol yaitu sebesar 80,74 > 69,03.

Nilai uji hipotesis independent sample t-tes pada data nilai posttest kognitif diperoleh rata-rata kelas eksperimen sebesar 78,97 dan rata-rata kelas kontrol sebesar 44,64, dengan output yang didapatkan Sig.(2-tailed) sebesar 0,000 < 0,05. Sedangkan hasil uji hipotesis hipotesis independent sample t-test pada data nilai posttest psikomotorik diperoleh rata-rata kelas eksperimen sebesar 80,74 dan kelas kontrol sebesar 69,03, dengan output yang didapatkan Sig.(2-tailed) sebesar 0,000 < 0,05. Sebagaimana dasar pengambilan keputusan dalam uji hipotesis, dapat disimpulkan bahwa (H0) ditolak dan (H1) diterima, dalam arti terdaapat perbedaan kompetensi kognitif dan psikomotorik dalam desain website antara pembelajaran berplatform website dengan Project Based Learning (PJBL) dan pembelajaran konvensional pada mata pelajaran konsentrasi keahlian website.

This research aims to design and implement the learning media SinauO! website platform and to determine the differences in students' cognitive and psychomotor competencies in website design between website platform learning with Project Based Learning (PJBL) and conventional learning on website expertise concentration subjects.

This research applies a Research and Development approach by adopting the ADDIE model. The trial design applied was Quasi Experimental with a Posttest Only Control Group Design format. The design of this learning media uses the PHP 8.2 programming language as the back-end, React JS as the front-end, the Laravel framework and MySQL database. Data from validation results of media, materials, lesson plans, questions, and student response questionnaires show a level of validity respectively, namely, 88% (very valid), 92% (very valid), 94% (very valid), 89% (very valid ), 95%(very valid). The average cognitive posttest score for the experimental class was greater than the control class, namely 78.97 > 44.64. Meanwhile, the average psychomotor posttest score for the experimental class was also greater than the control class, namely 80.74 > 69.03.

The independent sample t-test hypothesis test value on cognitive posttest score data obtained an experimental class average of 78.97 and a control class average of 44.64, with the output obtained Sig. (2-tailed) of 0.000 < 0, 05. Meanwhile, the results of independent sample t-test hypothesis testing on psychomotor posttest score data obtained an average of 80.74 for the experimental class and 69.03 for the control class, with the output obtained Sig. (2-tailed) of 0.000 < 0.05 . As the basis for decision making in hypothesis testing, it can be concluded that (H0) is rejected and (H1) is accepted, in the sense that there are differences in cognitive and psychomotor competence in website design between website platform learning with Project Based Learning (PJBL) and conventional learning in website expertise concentration subjects.
