Penelitian ini bertujuan untuk mengembangkan instrumen asesmen kete- rampilan memodelkan representasi pada topik ikatan kimia berbasis kerangka ker- ja 3D-LAP (The Three-Dimensional Learning Assessment Protocol). Instrumen yang dikembangkan dirancang untuk mengukur integrasi tiga dimensi pembelaja- ran, yaitu dimensi scientific ptactices, crosscutting concepts, dan disiplinary core ideas. Pengembangan instrumen dilakukan menggunakan model 4D (Define, De- sign, Develop, dan Disseminate) yang dibatasi sampai tahap Develop. Validasi ahli dilakukan oleh dosen pendidikan kimia dan guru kimia melalui expert judg- ment. Hasil validasi menunjukkan bahwa instrumen memiliki tingkat kesesuaian isi yang tinggi. Uji validitas empiris menunjukkan bahwa seluruh butir soal me- menuhi kriteria valid (rhitung > rtabel), dan hasil uji reliabilitas menunjukkan bahwa instrumen memiliki konsistensi internal yang baik. Instrumen asesmen yang di- kembangkan memiliki karakteristik soal yang mengintegrasikan representasi mak- roskopis, submikroskopis, dan simbolis dalam konteks ikatan kimia. Instrumen disusun dalam bentuk soal uraian terbuka yang menuntut kemampuan berpikir tingkat tinggi peserta didik. Subjek uji coba terdiri dari 33 peserta didik kelas XI di salah satu SMA di Lampung. Hasil tanggapan guru menunjukkan bahwa ins- trumen mudah digunakan, relevan dengan tujuan pembelajaran, serta dapat digu- nakan untuk menilai keterampilan peserta didik secara komprehensif. Berdasar- kan hasil tersebut, instrumen asesmen keterampilan memodelkan representasi ber- basis 3D-LAP dinyatakan valid, reliabel, dan layak digunakan dalam pembelaja- ran kimia di tingkat SMA. Kata kunci: instrumen asesmen, karakteristik instrumen asesmen, tanggapan guru, keterampilan memodelkan representasi, ikatan kimia. This study aims to develop an assessment instrument for representation mo- deling skills on the topic of chemical bonds based on the 3D-LAP (The Three-Di- mensional Learning Assessment Protocol) framework. The instrument develop- ped is designed to measure the integration of three dimensions of learning, namely the dimensions of scientific tactics, crosscutting concepts, and disciplinary core ideas. The development of the instrument was carried out using the 4D model (Define, Design, Develop, and Disseminate) which is limited to the Develop sta- ge. Expert validation was carried out by chemistry education lecturers and che- mistry teachers through expert judgment. The validation results showed that the instrument had a high level of content suitability. The empirical validity test sho- wed that all questions met the valid criteria (rcount > rtable), and the results of the re- liability test showed that the instrument had good internal consistency. The as- sessment instrument developed has the characteristics of questions that integrate macroscopic, submicroscopic, and symbolic representations in the context of che- mical bonds. The instrument is arranged in the form of open-ended descriptive questions that require students' high-level thinking skills. The trial subjects con- sisted of 33 grade XI students at a high school in Lampung. The results of teacher responses showed that the instrument was easy to use, relevant to learning objec- tives, and could be used to assess students' skills comprehensively. Based on the- se results, the 3D-LAP-based representation modeling skills assessment instru- ment was declared valid, reliable, and feasible to be used in chemistry learning at the high school level. Keywords: assessment instruments, characteristics of assessment instruments, teacher responses, representation modeling skills, chemical bonds.
