      Abstract
      Conductivity, Temperature, and Depth (CTD) merupakan instrumen oseanografi untuk memperoleh profil vertikal kolom perairan. Namun, CTD komersial relatif mahal dan bergantung pada sistem winch atau katrol. Penelitian ini bertujuan merancang dan membangun prototipe Profiler YoYo berbasis sistem ballast sebagai alternatif instrumen profiling vertikal otomatis. Sistem ballast dirancang menggunakan konsep Variable Buoyancy System (VBS) melalui piston yang digerakkan linear actuator untuk mengubah volume ballast dan gaya apung. Prototipe menggunakan mikrokontroler ESP32, sensor tekanan MS5837-30BA, dan baterai LiPo 6S. Pengujian dilakukan pada kolam sedalam 2 m untuk mengevaluasi kinerja ballast, kemampuan profiling, dan kebutuhan daya. Instrumen mencapai kedalaman maksimum 1,78 m dan 1,72 m, dengan waktu satu siklus profiling 27,8 detik dan 24,6 detik. Arus rata-rata sistem sebesar 0,679 A dengan estimasi waktu operasi baterai 8,84 jam. Prototipe berhasil melakukan profiling vertikal otomatis dan menjadi dasar pengembangan instrumen CTD berbiaya rendah dengan penambahan sensor konduktivitas pada penelitian selanjutnya.
       
      Conductivity, Temperature, and Depth (CTD) instruments are widely used in oceanographic surveys to obtain vertical profiles of water column properties. However, commercial CTD systems are relatively expensive and rely on winch-based deployment. This study developed a ballast-based Profiler YoYo prototype as a low-cost, automatic profiling alternative. The ballast system was based on the Variable Buoyancy System (VBS) concept, using a piston driven by a linear actuator to change ballast volume and buoyancy. The prototype integrates an ESP32 microcontroller, an MS5837-30BA pressure sensor, and a 6000 mAh 6S LiPo battery, tested in a 2 m-deep pool. The prototype reached maximum depths of 1.78 m and 1.72 m, with cycle times of 27.8 s and 24.6 s. Average current was 0.679 A, giving an estimated battery life of 8.84 h. The prototype demonstrated automatic vertical profiling and provides a foundation for future development of a low-cost CTD instrument through conductivity sensor integration.
