Hasil refleksi yang didapat peneliti selama kegiatan PPP berlangsung di SMKN 1 Kediri, saat proses belajar mengajar kurang lebih sebanyak 50% siswa yang kurang dalam keterampilan kolaborasi dan keterampilan komunikasi sehingga penguasaan materi baik secara kelompok atau individu yang telah diberikan oleh guru kurang diterima dengan maksimal. Sedangkan di pembelajaran abad 21 sekarang ini dibutuhkan keterampilan yang memiliki ciri yang disebut sebagai 4C, yaitu: Communication, collaboration, critical thinking and problem solving, creativity and innovation. Kembali pada tujuan peneliti yang diharapkan mampu menerapkan model pembelajaran MPA sehingga keterampilan komunikasi, kolaborasi dan hasil belajar setelah kegiatan belajar mengajar dapat meningkat.

Metode penelitian yang digunakan peneliti adalah Penelitian Tindakan Kelas (PTK), dimana teknik analisis datanya bersifat sikluistis. Data dikumpulkan dengan menggunakan Teknik observasi, angket dan tes. Teknik analisis data digunakan untuk mengolah data menjadi suatu bentuk yang mudah dibaca dan diinterpresentasikan dalam pengolahan data. Analisis hasil belajar untuk mengetahui ketuntasan klasikal dan idividual, analisis observasi dan angket dianalisis menggunakan rumus persentase hasil obsrvasi atau angket dan analisis keterlaksaan pembelajaran dianalisis dengan menggunakan rumus keterlaksanaan pembelajaran.  Subjek penelitian ini adalah siswa kelas X TKR 1 sebanyak 34 orang, dengan jenis kelamin laki-laki semuanya.

Hasil yang dicapai dari penelitian ini adalah: 1) Keterlaksanaan model pembelajaran market place activity terlaksana sesuai dengan langkah-langkah pembelajaran pada RPP. 2) Penerapan model market place activity dapat meningkatkan keterampilan komunikasi siswa pada mata pelajaran teknologi dasar otomotif. 3) Penerapan model market place activity dapat meningkatkan keterampilan kolaborasi siswa pada mata pelajaran teknologi dasar otomotif. 4) Penerapan model market place activity dapat meningkatkan hasil belajar siswa pada mata pelajaran teknologi dasar otomotif. Dengan demikian dapat disimpulkan bahwa penerapan model Market Place Activity dapat meningkatkan keterampilan belajar abad 21 sehingga hasil belajar siswa kelas X TKR 1 SMK Negeri 1 Kediri juga mengalami peningkatan

The results of the reflection obtained by the researchers during the PPP activities took place in Kediri 1 Vocational School, when the teaching and learning process was approximately 50% of students lacking collaboration skills and communication skills so that mastery of material either in groups or individuals that had been given by the teacher was not fully accepted. Whereas in the 21st century learning skills are now needed that have characteristics that are referred to as 4C, namely: Communication, collaboration, critical thinking and problem solving, creativity and innovation. Back to the objectives of the researchers who are expected to be able to apply the MPA learning model so that communication, collaboration and learning outcomes after teaching and learning activities can increase.

The research method used by researchers is Class Action Research (CAR), where the data analysis techniques are cyclical. Data was collected using observation techniques, questionnaires and tests. Data analysis techniques are used to process data into a form that is easy to read and interpret in data processing. Analysis of learning outcomes to determine classical and idividual completeness, analysis of observations and questionnaires were analyzed using the percentage formula of results of observation or questionnaire and analysis of learning rigor was analyzed using the formula of learning implementation. The subjects of this study were 34 students in class X TKR 1, with all male sexes.

The desired results of this study are that the danger in the work area can be reduced, the workers do The results achieved from this study are: 1) Implementation of the market place activity learning model is carried out in accordance with the learning steps in the lesson plan. 2) The application of the market place activity model can improve students' communication skills in subjects of basic automotive technology. 3) The application of the market place activity model can enhance students' collaboration skills in automotive basic technology subjects. 4) The application of the market place activity model can improve student learning outcomes in basic automotive technology subjects. Thus it can be concluded that the application of the Market Place Activity model can improve the learning skills of the 21st century so that the learning outcomes of TKR class X students of SMK Negeri 1 Kediri also increase.
