This study aims to analyze the relationship between economic growth and electricity consumption in Tomohon City, identifying the implications for energy infrastructure planning. A descriptive survey method was employed, using secondary data sourced from the Central Statistics Agency and PT PLN. Data on electricity supply and economic indicators such as Gross Regional Domestic Product (GRDP) were presented in tables, graphs, and diagrams to illustrate growth patterns from 2010 to 2021. Findings reveal that both electricity consumption and installed capacity have increased steadily, with electricity sales rising from 38.4 GWh in 2014 to 48.3 GWh in 2020 and customer numbers increasing from 24,575 to 29,770 over five years. Economic indicators such as GRDP also showed consistent growth, particularly in the tourism, trade, and accommodation sectors. The average annual growth in electricity production was 4.68%, highlighting the need for proactive energy planning. The study concludes that the economic development of Tomohon City is positively correlated with rising electricity demands. It recommends that stakeholders, including PT PLN and local government bodies, develop anticipatory infrastructure strategies to ensure sustainable energy supply, particularly as tourism continues to expand. This research provides critical insight into aligning energy provision with regional economic development priorities.

Abstract

This study details the design and implementation of a solar-powered Internet of Things (IoT)-based smart waste monitoring system, specifically developed to mitigate the persistent waste management challenges in Lagos, Nigeria. The primary goal was to create an automated, energy-efficient system capable of real-time monitoring of waste bin levels and environmental conditions. The developed prototype utilizes a NodeMCU ESP8266 microcontroller, integrating an ultrasonic sensor for waste level detection, an MQ-135 gas sensor for air quality assessment, and a DHT22 sensor for temperature and humidity measurement. The system is sustainably powered by solar energy, maintaining an average charging efficiency of 88% to ensure continuous operation. Real-time data is transmitted to a Firebase cloud database and displayed on a web dashboard, allowing waste management operators to proactively address bin overflows and harmful gas accumulation. Experimental results demonstrated that the system achieved an average accuracy rate of 95% in waste level detection. The findings confirm that IoT integration substantially enhances waste management efficiency, reduces the need for manual collection, and promotes sustainability through renewable energy use. The research concludes that combining IoT and solar technology offers a reliable, low-cost, and eco-friendly solution for urban waste management in energy-limited settings. The successful deployment in Lagos underscores its high scalability potential for other developing cities, contributing directly to the relevant Sustainable Development Goals (SDGs). Future work is recommended to incorporate machine learning for predictive collection optimization.
