s and opportunities, and formulate appropriate development strategies to create a greener campus. The research methods used include surveys, in-depth interviews, secondary data analysis, and field observations to gain a comprehensive understanding of the current situation. The findings of the study indicate that UMB faces several challenges, including the limited green open space, which only covers 15% of the total campus area, suboptimal waste management, and the low awareness of the academic community regarding environmental sustainability issues. However, there are several opportunities that can be leveraged, such as the utilization of renewable energy technologies, government policies that increasingly support environmentally friendly initiatives, and the potential for collaboration with external partners from both the private sector and government institutions. The proposed development strategy focuses on five main aspects. First, increasing the campus’s green open space to 30% of the total campus area. Second, the implementation of renewable energy, such as the installation of solar panels, to reduce dependence on fossil fuels. Third, waste management based on technology to effectively recycle waste. Fourth, the application of digital-based environmental education to raise awareness among the academic community. Fifth, maximizing student participation in sustainability activities. This strategy aims to reduce carbon footprints, improve resource efficiency, and create a campus ecosystem that supports the Sustainable Development Goals (SDGs).

ery which is paralleled to 24V. This voltage was then changed by the inverter to 220VAC to light 10 lights as research samples. Tests show that the LDR sensor works optimally at 5VDC voltage. If the voltage supplied is less or more than 5VDC, the sensor cannot function properly. Analysis of the conversion of ADC values to output voltage shows consistent results according to the test table. In addition, using 12VDC voltage directly on the LDR causes the sensor to not function because the LDR is designed for low voltage (≤5V). Without a suitable resistor, excessive current can damage sensor components. The system design is able to minimize the use of electricity sources from PLN and is an energy-saving solution for lighting dragon fruit plants in the field.

Abstrak: Rancangan sistem otomatisasi lampu pada tanaman buah naga menggunakan sensor LDR sebagai pendeteksi intensitas cahaya. Sistem ini didukung oleh modul surya berkapasitas 10-20 watt untuk menyuplai daya ke baterai 12V yang diparalel menjadi 24V. Tegangan ini kemudian diubah oleh inverter menjadi 220VAC untuk menyalakan 10 lampu sebagai sampel penelitian. Pengujian menunjukkan bahwa sensor LDR bekerja optimal pada tegangan 5VDC. Jika tegangan yang diberikan kurang atau lebih dari 5VDC, sensor tidak dapat berfungsi dengan baik. Analisis konversi nilai ADC ke tegangan output menunjukkan hasil yang konsisten sesuai tabel pengujian. Selain itu, penggunaan tegangan 12VDC langsung pada LDR menyebabkan sensor tidak berfungsi karena LDR dirancang untuk tegangan rendah (≤5V). Tanpa resistor yang sesuai, arus yang berlebih dapat merusak komponen sensor. Rancangan sistem mampu meminimalisir penggunaan sumber listrik dari PLN dan menjadi solusi hemat energi untuk penerangan tanaman buah naga di lapangan.
