Abstract

The lighting system significantly influences the growth and productivity of broiler chickens, necessitating an efficient tool for monitoring light intensity in chicken coops. This study aims to design and develop an Arduino IoT Cloud-based light intensity monitoring system for broiler chicken coops. The system employs two BH1750 light sensors, positioned inside and outside the coop, to measure light intensity, which is then processed by an ESP32 microcontroller. The collected data is displayed on a 16x2 LCD screen and uploaded in real time to the Arduino IoT Cloud platform for remote monitoring. Testing conducted over a 6-hour period revealed that light intensity inside the coop remained stable at approximately 30 lux from 09:30 to 12:52, while the highest external light intensity reached 400 lux between 12:06 and 14:40, followed by a decrease after 14:50. These findings indicate that the system can assist farmers in timely actions, such as opening or closing coop curtains, through effective monitoring via the Arduino IoT Cloud platform.

Abstract

Biomass-based activated carbon has potential as an electrode material in energy storage systems because it is renewable and environmentally friendly, but its performance is still dominated by the Electric Double Layer Capacitance (EDLC) mechanism. This study aims to examine the effect of surface modification of rice husk activated carbon using HNO3 on the specific capacitance of carbon paste electrodes in various types of electrolytes. Activated carbon was synthesized through the stages of carbonization, silica extraction, chemical activation using H3PO4, and surface modification using HNO3. Material characterization was carried out using X-Ray Fluorescence (XRF), Scanning Electron Microscope (SEM), Surface Area and Porosity with the Brunauer-Emmett-Teller (BET) method, Fourier Transform Infra-Red (FTIR), and Boehm titration. The electrochemical performance of the electrode was evaluated using the cyclic voltammetry method with HCl, KOH, and KCl electrolytes at a concentration of 0.5 M. FTIR and Boehm titration results showed an increase in the number of oxygen groups on the surface of activated carbon after modification. Electrochemical testing showed that the type of electrolyte affected the specific capacitance value, with KOH electrolyte producing the highest specific capacitance of 31.5094 mF/g on the modified activated carbon electrode (KAEM). This increase in capacitance was attributed to the contribution of the pseudocapacitance mechanism due to the interaction of oxygen functional groups on the surface of activated carbon with OH- ions, while in HCl and KCl electrolytes the charge storage mechanism was dominated by electric double layer capacitance.
