Stability of an Integrated Power Supply in a PV/Grid Network for an IoT System-Based BSF Maggot Farming Monitoring Controller

The potential for BSF maggot cultivation in the North Sumatra region for farmers is an alternative solution to develop the main feed for livestock and reduce the high level of organic waste in households. Apart from that, the management of BSF maggot cultivation will have an impact on the high demand from fish farmers and is also one of the favorite strategic businesses in trade, especially animal feed. To maximize the development of BSF maggot cultivation, one of them is to pay attention to the maggot cage by maintaining stable temperature and humidity to support the process from the egg-laying phase to breeding. Based on this, the aim of this research is to design an automatic system assisted by Android technology to spray water directly into the BSF maggot cage to maintain temperature and humidity so that BSF maggots can reproduce more optimally until they lay eggs. The research method uses mixed methods, both qualitative and quantitative approaches, using field observations and experiments to design technology for cultivating BSF maggots. The research results showed that the application of a technological system to BSF maggot cultivation by monitoring and controlling BSF maggot cages with the help of an Internet of Things (IoT) system integrated with additional electricity supplies using photovoltaic and grid to maintain the temperature and humidity in BSF maggot cages is more stable in supporting breeding. BSF maggot optimally. The tool can control and monitor the BSF Maggot cage using additional monitoring of the ThingSpeak application in the IoT and maintains a stable temperature of 31-32°C and humidity of 60-61%. Through government and community support, increasing creativity and innovation among BSF maggot cultivation businesses will be an important driver of reliable entrepreneurial behavior in the North Sumatra region.
