Abstract

Penelitian ini bertujuan untuk mengimplementasikan dan menganalisis sistem kendali robot ikan berbasis ESP32 yang memanfaatkan komunikasi Bluetooth dan aplikasi mobile sebagai antarmuka pengguna. Sistem dikembangkan dengan mengintegrasikan mikrokontroler ESP32, motor servo sebagai aktuator, serta modul komunikasi Bluetooth untuk memungkinkan pengendalian secara real-time. Metode penelitian yang digunakan adalah pendekatan eksperimental melalui tahap perancangan, implementasi, dan pengujian sistem. Pengujian dilakukan dalam dua kondisi, yaitu tanpa beban (dry testing) dan di lingkungan air untuk mengevaluasi respons sistem, stabilitas gerakan, serta keandalan komunikasi. Hasil penelitian menunjukkan bahwa sistem mampu merespons perintah pengguna secara cepat dengan tingkat delay yang rendah, serta menghasilkan gerakan yang stabil dan menyerupai gerakan ikan alami. Selain itu, komunikasi Bluetooth terbukti berjalan dengan baik dan mendukung pengendalian robot secara efektif melalui aplikasi mobile. Dengan demikian, sistem yang dikembangkan memiliki potensi untuk diterapkan dalam pengembangan robotika berbasis Internet of Things (IoT) dan sistem kendali cerdas

Abstract

Sugar palm (Arenga pinnata) sap tapping still relies on manual trimming of the inflorescence stalk surface using a machete. Although rotary cutting devices have been studied for several agricultural materials, quantitative evidence for a low-cost handheld machine specifically designed for sugar palm inflorescence stalk trimming is still limited. This study designed, fabricated, and evaluated a portable low-energy rotary cutting machine that integrates a rotary disc blade, DC worm gear motor, worm gearbox, rechargeable lithium battery, and protective blade cover. The novelty of the study is the task-specific evaluation of cutting time, operational capacity, energy consumption, battery-based trimming capacity, and prototype cost for smallholder sap tapping. Manual and machine-assisted trimming were compared using 20 repetitions for each method. The average cutting time decreased from 22.4 ± 1.1 to 6.8 ± 0.6 s/stalk, corresponding to a 69.64% reduction and 3.29 times faster operation than manual trimming. Operational capacity increased from 160.7 to 529.4 stalks/hour. The machine operated at 10.8 V and 0.95 A, requiring 10.26 W and 0.0194 Wh/stalk. A fully charged 10.8 V, 4.8 Ah battery can theoretically support approximately 2675 trimming operations before complete drainage. The prototype material cost was Rp 433,000, equivalent to approximately USD 24.25 using an exchange rate of Rp 17,856/USD. The results indicate that the developed device is a feasible low-cost and low-energy mechanization option for repetitive sugar palm inflorescence stalk trimming.
