<em>In the Work </em><em>System Design</em><em> Laboratory at </em><em>UPH</em><em>, there are anthropometric measuring </em><em>tools</em><em> for standing position and sitting position. Based on the</em><em> tools</em><em> evaluation, it was found that </em><em>they were</em><em> less efficient because </em><em>of the need for </em><em>repeated </em><em>tool </em><em>adjustments</em><em>. Furthermore, two observers were needed</em><em> </em><em>to collect</em><em> </em><em>anthropometric </em><em>data</em><em> and they had to read the scale manually</em><em>. Therefore, a new digital and portable anthropometric</em><em> measuring</em><em> tool was </em><em>developed to overcome the problem</em><em>. The Gea HT721 measuring instrument was chosen as an alternative to a new anthropometric</em><em> measuring</em><em> tool that uses ultrasonic ranging technology to measure distances. </em><em>A </em><em>supporting tool</em><em> (similar to a caliper)</em><em> </em><em>was also developed </em><em>to support the </em><em>anthropometric </em><em>measurement process. An evaluation of the new anthropometric</em><em> measuring</em><em> tool was carried out by calculating the average percent error</em><em> and</em><em> a comparison of the total time for data collection. The results of the average percent measurement error </em><em>was</em><em> 0.58%.</em><em> According to the paired t-test, t</em><em>here was no</em><em> significant</em><em> difference in the average of</em><em> measured </em><em>body dimensions using the new and </em><em>the previous</em><em> </em><em>tool</em><em>s</em><em>.</em><em> </em><em>The new anthropometric tools can reduce data collection time by 32% for standing positions and 11% for sitting positions</em><em>.</em><em></em><p align="justify"><strong>Bahasa Indonesia Abstract:</strong></p><p align="justify">Pada Laboratorium Analisis Perancangan Kerja (APK) di UPH terdapat alat ukur antropometri posisi berdiri dan posisi duduk. Berdasarkan evaluasi alat antropometri tersebut, ditemukan bahwa alat kurang efisien karena membutuhkan penyetelan alat yang berulang yang juga membutuhkan lebih dari satu pengamat saat pengambilan data. Selain itu, pengamat sering mengalami kesulitan pembacaan hasil pengukuran manual pada meteran. Oleh karena itu, dibuat alat antropometri jenis baru yang bersifat digital dan portabel. Alat ukur Gea HT721 dipilih sebagai alternatif alat antropometri baru yang menggunakan teknologi ultrasonic ranging untuk mengukur jarak. Setelah itu, dirancang dan dibuat suatu alat pendukung yang menyerupai jangka sorong untuk mendukung proses pengukuran data antropometri. Evaluasi alat antropometri baru dilakukan dengan menghitung rata – rata persen error, serta perbandingan total waktu pengambilan data. Hasil rata – rata persen error pengukuran adalah 0,58%. Hasil uji paired t test menunjukkan bahwa tidak terdapat perbedaan signifikan antara rata-rata hasil pengukuran dimensi tubuh menggunakan alat ukur antropometri jenis baru dengan hasil pengukuran menggunakan alat yang lama. Berdasarkan perbandingan total waktu pengambilan data terdapat penurunan waktu sebesar 32% untuk data antropometri posisi berdiri dan 11% untuk data antropometri posisi duduk.</p>
