<![CDATA[Traditional small-scale vessels (<10 GT) in high-traffic maritime corridors like the Bali Strait face severe collision risks and unpredictable microclimate changes due to the prohibitive cost and power demands of commercial Automatic Identification Systems (AIS). This study presents the design, physical deployment, and field evaluation of a low-cost, solar-powered LoRa-based Mini AIS integrated with a localized weather monitoring node and an electronic fish aggregator. The hardware prototype features an ESP32-S3 microcontroller, Neo-6M GPS, BME280 microclimate sensors, and a LoRa RFM95W (915 MHz) transceiver, sustained autonomously by a 20 Wp solar photovoltaic system. Empirical field testing was conducted over 14 days on a traditional wooden tourist boat to evaluate wireless telemetry propagation, power management endurance, and real-time sensor validity. Field results demonstrated a fully self-sustained 24-hour operational cycle with an average daily energy generation of 91 Wh, easily covering the 24.2 Wh system load. The maritime communication network achieved a maximum effective telemetry range of 9.2 km with an 81.5% Packet Delivery Rate (PDR). Furthermore, real-time weather telemetry exhibited a remarkably strong correlation ($R^2 = 0.985$) with official BMKG reference data. The coastal receiver gateway successfully routed real-time vessel tracking logs into the open maritime aggregator Marine Traffic via MQTT protocol. This multi-functional implementation provides a robust, economically viable solution that significantly enhances navigational safety standards and operational efficiency for non-SOLAS maritime fleets.]]>
