Abstract
Science and technology are constantly advancing in every era, much like aerodynamics. At Sultan Ageng Tirtayasa University, there is one Renewable Energy Engineering Lab that has a wind tunnel but lacks equipment to measure drag and lift forces. Therefore, researchers have developed a measurement tool for these forces. There are a few steps that need to be taken in order to finish this research project. These include a literature review, design work, and experimental studies, which include calibration testing to determine the gauge R&R values and direct performance testing with the NACA S1046 airfoil. The calibration results showed the highest standard deviation for drag force to be 0.25 and for lift force to be 0.8. For drag force testing, the gauge R&R value was found to be 0.678%, and for lift force testing, it was 1.828%. These values are below 10%, indicating that this measurement tool is acceptable based on the Gauge R&R variance study criteria. This measurement tool can be considered acceptable. During testing with the NACA S1046 airfoil, the measurement tool performed well at speeds ranging from 1 to 5 m/s because the standard deviation was not too large, whereas at a speed of 6 m/s there was a tendency for a high standard deviation in lift force. This measurement tool can be used with a maximum test object weight of 0.7 kg.

| Additional Information: | Ilmu pengetahuan dan teknologi selalu berkembang setiap jaman seperti ilmu aerodinamika. Di Lab Rekayasa Energi Baru Terbarukan Universitas Sultan Ageng Tirtayasa terdapat salah satu yang memiliki terowongan angin, namun belum memiliki alat ukur gaya hambat dan gaya angkat, oleh karena itu peneliti membangun alat ukur gaya hambat dan gaya angkat tersebut. Ada beberapa tahap penelitian yang harus dilakukan yaitu studi pustaka, perancangan, dan studi eksperimen dengan melakukan pengujian mulai dari kalibrasi lalu mencari nilai Gauge R&R, dan melakukan pengujian performa dengan airfoil naca S1046. Hasil dari kalibrasi didapakan standar deviasi tertinggi pada gaya hambat adalah 0,25, dan pada gaya angkat adalah 0,8. Lalu nilai Gauge R&R untuk pengujian gaya hambat adalah 0,678% dan pengujian gaya angkat adalah 1,828%, nilai tersebut di bawah 10% sehingga berdasarkan batasan studi varian Gauge R&R alat ukur ini bisa dikatakan acceptable. Lalu pada pengujian dengan airfoil NACA S1046 didapatkan pengukuran yang terbaik pada kecepatan 1 sampai 5 m/s karena hasil standar deviasinya tidak terlalu besar, sedangkan di kecepatan 6 m/s sudah memiliki standar deviasi pada gaya angkat yang cenderung tinggi. Alat ukur ini bisa digunakan dengan beban benda uji maksimal 0,7 kg. | |||||||||
