Abstract

The era of globalization and current technological developments towards a packaging need, one of which is edible plastic packaging that can be consumed. Antioxidants are compounds that can prevent and repair damage to body cells from free radicals. This study aims to determine the antioxidant activity value (% inhibition) of the Kecombrang flower extract before it becomes edible plastic and after it becomes edible plastic, then the finished edible plastic product characterizes its physical and chemical properties, and applies it to apples. From the test results obtained the best concentration is edible plastic Kecombrang flower extract 25% from the maceration extraction process. The tests carried out obtained % inhibition from the extract by 58% and from edible plastic finished products by 55%, the tensile strength value of 22.11 MPa, the value of water resistance of 18.64%, the detection of FT-IR contains many functional groups of phenols and flavonoids, and the application of apples for 12 hours did not change / the condition of the apples remained fresh.

Abstract

A greenhouse is a controlled environment designed to enhance plant productivity by regulating microclimatic conditions. However, in many greenhouse systems, the irrigation process is still performed manually, resulting in suboptimal water use efficiency and inconsistent watering schedules. The SMASHTHETIC greenhouse serves as a cultivation facility for the moth orchid (Phalaenopsis amabilis), which requires precise control of substrate moisture and ambient humidity to ensure optimal growth and flowering. This study aims to design and implement an automatic irrigation system based on Arduino and the Internet of Things (IoT) to improve irrigation efficiency in the SMASHTHETIC greenhouse. The system consists of a soil moisture sensor, Arduino microcontroller, Wi-Fi module (ESP8266/ESP32), and actuators such as a water pump and solenoid valve to regulate water flow. IoT integration enables real-time monitoring and remote control via web and smartphone applications. Experimental results show that the system automatically adjusts watering frequency and duration based on soil moisture data, providing convenience for users and reducing manual intervention. Therefore, this study demonstrates that the integration of Arduino and IoT technologies in greenhouse irrigation supports the development of smart agriculture practices that are more efficient, sustainable, and productive.
