Abstrak Sudut kontak merupakan parameter penting untuk mengetahui tingkat hidrofobisitas suatu material. Selain itu sudut kontak dapat digunakan untuk mengetahui informasi mengenai energi permukaan, kekasaran, dan heterogenitas suatu material. Hidrofobisitas merupakan karakteristik material yang memiliki dampak signifikan terhadap implementasi material maju untuk mendukung inovasi teknologi terkini. Pengukuran sudut kontak yang presisi menjadi hal yang penting untuk mendapatkan nilai yang akurat. Namun Pengukuran sudut kontak secara manual masih banyak dijumpai dalam lingkup penelitian skala individu dan umum akibat alat dan akses yang terbatas. Penelitian ini bertujuan untuk membuat aplikasi mobile yang dapat mengukur sudut kontak dengan lebih mudah dengan menggunakan bantuan software dengan bahasa pemrograman JavaScript dengan framework react native v.0.73.4 dan expo v.50.0.14 dengan menggunakan metode Agile. Metode yang digunakan dalam aplikasi pengukuran sudut kontak ini adalah pengukuran sudut kontak statis dengan sistem tetesan air menggunakan pendekatan fitting bentuk lingkaran. Hasil pengujian black box testing menunjukkan nilai yang signifikan 87.5% dengan sedikit masalah pada penyimpanan PDF mode pengambilan gambar melalui galeri. Selain itu aplikasi yang dihasilkan menampilkan fitur video dan indikator waktu yang belum ada di aplikasi yang telah ada. Sedangkan untuk hasil uji UAT sebesar 89% dimana hasil ini cukup dapat dijadikan acuan keberhasilan pembuatan aplikasi MyAngleMeter. Penelitian ini selanjutnya diharapkan dapat menjadi salah satu solusi untuk memudahkan pengguna secara operasional, serta memiliki tingkat akurasi yang lebih baik dibandingkan dengan pengukuran manual.

Abstract [A Contact Angle Measurement Application For Hydrophobic Materials Using The React Native Framework] Contact angle is an important parameter for determining the hydrophobicity level of a material. In addition, the contact angle can provide information regarding surface energy, roughness, and heterogeneity of a material. Hydrophobicity is a material characteristic that significantly impacts the implementation of advanced materials to support current technological innovations. Precise contact angle measurement is essential to obtain accurate values. However, manual contact angle measurement is still commonly found in individual and general research settings due to limited equipment and access. This study aims to develop a mobile application that can measure contact angles more easily by utilizing software built with the JavaScript programming language using the React Native framework (v.0.73.4) and Expo (v.50.0.14), adopting the Agile methodology. The method used in this contact angle measurement application is static contact angle measurement using a water droplet system with a circular fitting approach. The results of black box testing showed a significant accuracy of 87.5%, with minor issues in PDF storage when using the image capture feature via the gallery. Furthermore, the developed application includes a video feature and a time indicator, which are not available in existing applications. The User Acceptance Testing (UAT) results reached 89%, indicating a relatively successful outcome for the development of the MyAngleMeter application. This research is expected to serve as one of the solutions to facilitate users operationally, while offering better accuracy compared to manual measurements.
