<![CDATA[Abstrak: Kemampuan keterampilan merancang alat eksperimen siswa kelas microcontroller SMAN X masih rendah dan perlu ditingkatkan. Salah satu faktor penyebabnya yaitu terbatasnya ketersediaan alat dan fasilitas pendukum dalam praktikum eksperimen termodinamika. Pengabdian ini bertujuan untuk memberikan pendampingan dalam pembuatan alat eksperimen termodinamika terintegrasi Internet of Things (IoT) bagi siswa. Metode pelaksanaan pengabdian menggunakan pendekatan Service Learning (SL) berbasis eksperimen. Peserta mitra terdiri dari 16 siswa dari kelas XI dan XI pada peminatan kelas microcontroller. Evaluasi kegiatan dilakukan dengan cara mengisi lembar observasi yang mencakup tiga kategori aspek keterampilan yaitu merancang alat, mengaplikasikan program, serta mencoba memadukan alat dengan program. Hasil pengabdian menunjukkan bahwa siswa terampil membuat alat eksperimen terintegrasi IoT dengan rerata persentase kategori sangat baik dan baik sebesar 95%. Melalui kegiatan ini diharapkan keterampilan siswa dalam membuat alat eksperimen semakin meningkat, sehingga mendorong motivasi, kreativitas, dan inovasi siswa dalam proses pembelajaran.Abstract: The ability to design experimental tools for microcontroller class students at SMAN X is still low and helps to be improved. The contributing factor is the limited availability of tools and supporting facilities in thermodynamics experimental practicums. This community service aims to provide assistance in making thermodynamics experimental tools integrated with the Internet of Things (IoT) for students. The community service method uses an experiment-based Service Learning (SL) approach. Partner participants consisted of 16 students from grades XI and XI in the microcontroller class interest. Evaluation of the program was carried out by filling out an observation sheet that covered three categories of skill aspects, namely designing tools, applying programs, and trying to integrate tools with programs. The results of the community service show that students are skilled at making IoT integrated experimental tools with an average percentage of very good and good categories of 95%. Through this program, it is hoped that students' skills in making experimental tools will increase, thereby encouraging student motivation, creativity, and innovation in the learning process.]]>
