The catfish (Pangasius sp.) is a popular freshwater fish among consumers, both in Indonesia and internationally. One of the main challenges in catfish farming is the suboptimal use of feed. The commonly used feed consists of natural and artificial types. Natural feed is divided into two categories: animal-based and plant-based. The animal-based natural feed frequently used by farmers is tubifex worms. However, tubifex worms have a drawback, as their availability in the market is limited. Therefore, a study was conducted to explore the use of Azolla as an alternative feed for catfish. This study used a Completely Randomized Design (CRD) with one treatment and two levels, namely 100% Azolla and 100% tubifex worms. The study was conducted over a period of 14 days. The observed parameters included fish growth (length and weight), survival rate (SR), Feed Conversion Ratio (FCR), and water quality (temperature, pH, and dissolved oxygen). The data from the study were analyzed using a mean value test. The results showed that the use of Azolla as feed had a positive impact on catfish growth, although it was not yet effective in fully replacing 100% tubifex worms. There was an increase in biomass of 13.8 grams and an average length increase of 0.56 cm during the 14-day maintenance period.

Forest and land fires are natural disasters that often occur in Indonesia, especially during the dry season. These fires cause enormous environmental damage, economic losses, and social problems. In fact, large forest and land fires result in devastating smoke impacts beyond state administrative boundaries (transnational disasters).  The type of research that the author will use in this research is normative juridical. The use of this type of normative juridical research is because the object of study is related to legal principles and principles as well as theories and opinions of legal experts. It can be said that normative juridical research is literature research.  In general, forest fires that occur in Indonesia are caused by three main factors, namely fuel conditions, weather and social and cultural conditions of the community. Fuel conditions that are prone to fire hazards are their abundance on the forest floor, relatively low water content (dry), and continuous fuel availability. Climatic factors in the form of temperature, humidity, wind and rainfall also determine fire susceptibility. High temperatures due to direct sunlight cause fuel to dry out and become flammable, high humidity (in forests with dense vegetation) reduces the chance of forest fires occurring, wind also influences the fuel drying process and the speed at which fire spreads while rainfall influences the size of the fire. water contained in the fuel.
