This study aims to design and develop an automatic solar tracker system based on the Internet of Things (IoT) to enhance the efficiency of energy collection in solar panels. The system utilizes key components such as the ESP32 microcontroller, LDR sensors, servo motors, and the Blynk platform to monitor performance in real-time. The solar tracker is designed to follow the movement of the sun, ensuring that the solar panels are always positioned optimally to receive sunlight throughout the day. Testing indicates that this system improves solar energy absorption efficiency compared to static solar panel systems. Furthermore, the integration of IoT allows for more effective and efficient remote control and monitoring. Thus, this technology not only offers improvements in energy efficiency but also provides a practical solution for better and more sustainable solar energy management.

Emisi merupakan hal yang sangat serius untuk di atasi, emisi gas karbon monoksida merupakan sisa dari kombusi yang dilakukan oleh kendaraan bermotor seperti motor maupun mobil. Gas ini bersifat tidak berbau maupun berwarna, namun mematikan dalam dosis yang tinggi. Sehingga perlu penanganan serius untuk memantau gas jenis ini. Universitas Semarang merupakan salah satu universitas dengan jumlah mahasiswa terbanyak di Jawa Tengah, maka secara otomatis pengendara kendaraan bermotor pun ikut meningkatkan kandungan gas karbon monoksida di area parkir. Oleh karena itu, penelitian ini memiliki tujuan untuk mendesain sebuah purwarupa deteksi karbon monoksida dengan menggunakan teknologi Internet of Things yang dapat melaporkan ketika terdapat kandungan gas di udara. Model ini dilengkapi dengan sensor MQ-9 yang mampu mendeteksi gas karbon monoksida lebih akurat dibandingkan model-model sebelumnya. Berdasarkan hasil evaluasi yang dilakukan, model ini mampu mendeteksi gas dengan rata-rata 4,17 ppm dari 55 data deteksi yang ada dan tersimpan di Firebase Realtime Database. Dari semua data yang ada, model mendeteksi puncak tertinggi mencapai 18,365 ppm. Meskipun terdapat kenaikan kandungan gas, namun hasil ini masih di bawah batas aman yang dianjurkan. Selain itu, hasil terakhir yang didapatkan dari model ini adalah notifikasi pelaporan yang disampaikan melalui Telegram Bot.

The P2TL rule is an abbreviation for the Collision Prevention Regulation at Sea, a rule that makes it easier for ships to sail safely and avoid the danger of collisions between 2 or more ships. The aim of this research is to explain the application of P2TL rules when ships are sailing to reduce the risk of collisions between ships and create safety in navigation on MV ships. Meratus Palembang. This research was carried out using quantitative descriptive statistical research methods. With data collection techniques based on the results of questionnaires, observations, literature studies related to P2TL regulations during maritime guard duty. Then the data was analyzed using SPSS calculations and described. Based on the research results, it was concluded that the P2TL rules were applied during maritime guard duty on the MV. Meratus Palembang has complied with established procedures. This is to ensure safety at sea by preventing accidents that could result in loss of life, damage to ships, and potential environmental pollution at sea.

The small number of people cultivating horticultural crops, especially vegetables, means that people can only buy vegetables to meet their vegetable food needs, where the main factor for this is the decline in the area of productive land used as agricultural land and cultivation caused by the growth of population density in Indonesia. Therefore, the solution to the existing problem is to provide openness of insight and assistance in utilizing narrow land for plant cultivation. One way to cultivate plants is by using the vertical cultivation method. In implementing this activity, the aim is for Kalijudan residents to have knowledge about the vertical cultivation system and plastic bottle waste management. The implementation of this activity uses the method of socialization and training activities or direct practice. Where, the target audience in the practice of this activity is elementary school students and Kalijudan residents. From the results of the discussion, it was concluded that this activity is useful because it can introduce residents and change the condition of the Kalijudan sub-district which was originally a narrow land without plants into a narrow but green land. In addition, this vertical cultivation activity also has benefits in reducing plastic waste that accumulates in the Kalijudan environment.
