Abstract

Protokol standard yang dipakai di lingkungan pendidikan, bisnis, perumahan, dan industri di Indonesia masih mengandalkan protokol standard yaitu Wifi, dan Bluetooth. Penelitian terapan ini behubungan dengan sebuah prtokol standard yaitu Zigbee yang merupakan standard IEEE 802.15.4 yang sudah mulai banyak digunakan pada jaringan untuk keperluan kontrol berbasis IoT. Dalam teknologi smart home, konektivitas menjadi hal yang sangat penting. Untuk membangun sebuah sistem Smart home, pengguna harus mempertimbangkan keterhubungan atau komunikasi satu perangkat smart home dengan perangkat yang lain. Jaringan protocol komunikasi prangkat smart home yang saat ini paling familiar dan banyak digunakan adalah WIFI. Namun sekarang juga mulai bermunculan alternatif protokol konektivitas nirkabel, salah satunya adalah zigbee. Zigbee merupakan salah satu standar duniauntuk jaringan berdaya rendah, berjarak dekat, menawarkan solusi Internet on Thing (IoT) yang lengkap dan dapat dioperasikan untuk Rumah serta gedung.Zigbee memiliki fitur yang mampu mengatur jaringan sendiri maupun pertukaran data pada jaringan, serta zigbee dapat mendukung ratusan alat dan memiliki fitur keamanan yang dapat dihandalkan.. Didalam penelitian terapan ini monitoring menggunakan protocol zigbee dengan, topologi klaster yang terdiri atas zigbee koordinator dan beberapa perangkat akhir zigbee yang akan dipasang pada lokasi yang berpenghalang dinding maupun yang tanpa penghalangan

Abstract

This study aims to analyze electrical energy consumption and identify energy-saving opportunities in Bodas Crystal Ice Industry through an energy audit. The method applied is a quantitative descriptive energy audit involving historical consumption data, load measurements, and Specific Energy Consumption (SEC) analysis. The average electricity consumption was 6,253 kWh per month, of which ice production and refrigeration accounted for more than 95%. The initial SEC was 386 kWh/ton. After correcting the combined scenario to avoid double-counting freezer savings, the estimated consumption decreased to 4,852 kWh per month, equivalent to a 22.4% saving, while SEC decreased to 299.5 kWh/ton. These values represent technical-economic estimates that require verification after implementation. Keywords: Energy Audit, Specific Energy Consumption, Ice Production Industry, Refrigeration System, Energy Saving

Abstract

This research successfully developed and implemented an integrated soil moisture monitoring system based on the Internet of Things (IoT), utilizing the ESP32-S3 microcontroller. The system is specifically designed for the cultivation of Bougainvillea Singapore bonsai, aligning with the principles of smart agriculture. The primary function is to monitor soil moisture conditions in real-time and automatically classify the sensor data. Classification is achieved through an If-Else logical method, defining three distinct conditions that also control the irrigation actuator: dry (0%–25%), which triggers the pump ON; moist (26%–69%), which keeps the pump OFF; and wet (70%–100%), which also maintains the pump in the OFF state. The system demonstrated good accuracy in identifying soil moisture status. This success not only validates the system's design but also confirms the significant application potential of this technology for further development as a precise and automated solution supporting optimization within sensor-based smart farming systems.
