Abstract

Banjir merupakan bencana alam yang menjadi langganan beberapa kota besar di Indonesia, ketika memasuki musim penghujan. Oleh sebab itu banyak pihak yang mengembangkan flood early warning system (FEWS), seperti yang dikembangkan oleh BPPT di aliran sungai Cibongas. Seiring berjalannya waktu dalam pengimplementasian alat tersebut perlu dilakukan pengecekan dan perbaikan, untuk memastikan hasil pengukuran sensor pendeteksi curah hujan dan ketinggian  permukaan air sungai tetap presisi dan dapat terkirim ke server scara berkala menggunakan komunikasi GSM. Pengecekan dan perbaikan dibagi menjadi dua bagian, system dan fisik. Secara system dilakukan penggantian data logger yang telah disiapkan sebelumnya dimana di dalamnya sudah diperbaharui firmware, card I/O, baterai RTC, fuse, dan SIM card regular operator baru dengan sistem pembayaran pasca bayar. Peraturan baru mengenai pembatasan user dalam memiliki jumlah SIM card maksimal 3 buah saja. Secara fisik pengecekan dan perbaikan alat disebabkan oleh dua penyebab, faktor alam dan faktor manusia. Faktor alam rumput tinggi yang perlu dipotong secara periodik, lumut menutupi alat sensor curah hujan perlu dibersihkan juga, sarang serangga yang menutupi sensor sonar juga perlu dibersihkan dan karat pada gembok diminimalisir dengan disemprotkan WD40. Faktor manusia yang tidak bertanggung jawab memasukkan batu kedalam sensor curah hujan dimana perlu dibersihkan dan yang mengendurkan ulir antena dimana perlu di kencangkan lagi ulirnya.Diperlukan sinergitas dalam menjaga alat FEWS ini, baik dari segi menyikapi faktor alam, oknum yang tidak bertanggung jawab, dan teknis peralatannya, supaya manfaatnya dapat dinikmati masyarakat banyak dan meminimalisir jatuhnya korban jiwa maupun harta.

Abstract

Relay sprint performance is influenced by the efficiency and synchronization of baton exchanges, yet current evaluation methods remain largely subjective and fragmented. This study aimed to develop and evaluate an integrated Smart Relay Baton and multisensor wearable system for objective and real-time assessment of relay performance. A research and development approach based on the Borg–Gall model was employed, followed by a quasi-experimental pre–post design involving 241 sprint relay athletes. The system integrated accelerometer-based motion tracking within the baton and physiological monitoring through wearable sensors and smartwatch support, with synchronized data transmission via an MQTT-based IoT architecture. Key variables included transition time, entry speed, average acceleration, synchronization delay, heart rate response, rating of perceived exertion (RPE), and the Relay Performance and Orchestration Index (RPOI). Results showed pre–post changes in transition time (Cohen’s dz = −0.82), synchronization delay (dz = −0.74), entry speed (dz = 0.74), average acceleration (dz = 0.48), and RPOI (dz = 1.05). Heart rate during the exchange showed a small reduction (dz = −0.32), while 60-s heart rate recovery increased (dz = 0.54) and RPE decreased (dz = −0.75). These findings indicate that the integrated system can provide comprehensive, data-driven information on baton exchange and relay performance by combining movement and physiological measures. However, the observed changes represent within-participant differences and should not be interpreted as evidence of a causal effect of the system or as evidence of pedagogical effectiveness.
