Abstract

The utilization of small-scale solar panels, particularly those with a capacity of 50 Wp, has become increasingly widespread in household systems and remote areas. However, the lack of adequate monitoring systems makes it difficult for users to identify actual panel performance, causing efficiency degradation to often go undetected at an early stage. This study aims to develop a current and voltage monitoring system for a 50 Wp solar panel based on the Internet of Things (IoT) that is capable of providing real-time performance data to support performance evaluation and more efficient energy management. The system was developed using current and voltage sensors, an ESP32 microcontroller, and a cloud-based IoT application for data visualization. The test results indicate that the system is able to monitor daily variations in current and voltage with good accuracy and stable data transmission. The measured output power of the solar panel ranges from 1 to 1.4 W, or approximately 2–3% of the nominal capacity, which is influenced by solar radiation intensity, panel temperature, and system losses. The proposed IoT-based monitoring system has proven effective in recording the actual performance of the solar panel and providing real-time information that is useful for performance evaluation and optimization of small-scale solar energy utilization.

Abstract

Desa Lobbo Kecamatan Beo Utara, Kabupaten Kepulauan Talaud merupakan salah satu daerah yang  memiliki potensi ekosistem pesisir yang belum banyak terdokumentasi, khususnya ekosistem lamun. Ekosistem lamun memberikan kontribusi yang besar secara ekologis di pesisir, selain sebagai habitat biota dapat juga berperan dalam menjaga kestabilan substrat dan arus perairan. Lamun sebagai satu-satunya tumbuhan berbunga yang tumbuh di laut, menjadi salah satu produsen yang berperan dalam rantai makanan sehingga keberadaannya perlu mendapat perhatian. Pesisir sebagai salah satu lokasi yang erat dengan berbagai aktivitas manusia, terutama nelayan dalam mencari ikan atau sebagai tempat tambatan perahu, jalur transportasi laut, tentunya ikut mempengaruhi keberadaan dari lamun itu sendiri. Penelitian ini bertujuan untuk mengidentifikasi jenis lamun dengan menggunakan metode line transek dengan Teknik  jelajah pada area yang telah ditentukan  tempat tumbuhnya lamun yaitu dibelakang pemukiman penduduk yang menjadi tempat tambatan perahu nelayan dan sarana transportasi air yang berada di bagian tengah desa Lobbo.  Pengambilan data dan pengukuran faktor fisik kimia lingkungan dilakukan bersamaan dengan pengambilan data jenis lamun. Hasil penelitian menunjukkan bahwa terdapat 2 jenis lamun dari 1 famili Cymodoceaceae yaitu  Halodule uninervis dan Halodule pinifolia yang tersebar secara berkelompok pada area tertentu. Hasil pengukuran Suhu, Salinitas, pH dan kecepatan arus mendukung keberadaan lamun Lobbo Village, North Beo District, Talaud Islands Regency is one of the areas that has potential coastal ecosystems that have not been widely documented, especially seagrass ecosystems. Seagrass ecosystems make a significant ecological contribution to the coastline. In addition to providing a habitat for biota, they also play a role in maintaining substrate stability and water currents. Seagrass, as the only flowering plant that grows in the sea, is one of the producers that plays a role in the food chain, so its existence needs attention. The coast, as a location closely related to various human activities, especially fishermen in search of fish or as a place to moor boats and a sea transportation route, certainly affects the existence of seagrass itself. This study aims to identify seagrass species using a Line transec method with explore in a predetermined area where seagrass grows, namely behind residential areas that serve as mooring places for fishermen's boats and water transportation facilities. Data collection and measurement of physical and chemical environmental factors were carried out simultaneously with the collection of seagrass species data. The results of the study show that there are two types of seagrass from the Cymodoceaceae family, namely Halodule uninervis and Halodule pinifolia, which are scattered in groups in certain areas. The results of measurements of temperature, salinity, pH and current velocity support the existence of seagrass
