Due to particular conditions, sometimes actual height can not be measured. Thus, this study was conducted to develop height prediction model of adolescent from knee height and ulna length. This cross sectional study involved 205 students of SMPN 7 Depok and SMAN 6 Depok. Subjects’s identity was recorded using questionairre, while stature height, knee height, and ulna length was measured directly. Prediction models was developed using multiple regression. Height prediction model from knee height has the highest R2 and the lowest MAE with equation Height (cm) = 38,422 - 1,878 Sex + 1,453 Age (year) + 2,071 knee height (cm).

Tinggi badan aktual terkadang tidak dapat diukur karena beberapa kondisi tertentu. Oleh karena itu, penelitian ini bertujuan mengembangkan model prediksi tinggi badan pada remaja berdasarkan tinggi lutut dan panjang ulna. Penelitian pontong lintang ini melibatkan 205 murid SMPN 7 Depok dan SMAN 6 Depok. Data identitas subjek diperoleh melalui pengisian kuesioner, sedangkan tinggi badan, tingi lutut, dan panjang ulna diukur langsung. Model prediksi dikembangkan menggunakan regresi ganda. Model prediksi tinggi badan dari tinggi lutut memiliki R2 terbesar dan MAE terkecil dengan persamaan Tinggi Badan (cm) = 38,422 - 1,878 Jenis Kelamin + 1,453 Umur (thn) + 2,071 Tinggi Lutut (cm).
