**Budikdamber: A Sustainable and Efficient Aquaculture System**

Budikdamber, a combination of "budidaya ikan" (fish farming) and "ember" (bucket), is a simple yet effective method of raising fish and vegetables simultaneously. This system utilizes a single 80-liter bucket to cultivate both lele (catfish) and kangkung (water spinach). The process begins with preparing the bucket. First, holes are drilled into the bottom of the bucket to install a drain tap, facilitating easy water changes and removal of ammonia and fish waste. Additional holes are drilled in the lid of the bucket to allow the roots of the kangkung to access the water. Next, the bucket is filled with water and left to settle for two days. This allows any impurities to settle at the bottom. After the water has settled, 60 to 100 lele fingerlings, measuring 7-8 cm or 8-9 cm, are introduced into the bucket. To create the aquaponic component, kangkung cuttings or seedlings are placed in a separate container, such as a gallon jug, and suspended above the water in the bucket. The roots of the kangkung will grow down into the water, absorbing nutrients from the fish waste. Charcoal and coral are added to the bucket to further enhance the system. Charcoal provides support for the kangkung cuttings and helps to filter the water. Coral, on the other hand, acts as a natural detoxifier, neutralizing harmful substances in the water. The use of kangkung cuttings instead of seedlings allows for a faster harvest, with the first harvest occurring after 14 days. However, if you prefer to start with seedlings, it will take longer for the kangkung to mature. Budikdamber offers several advantages. It is a sustainable system that promotes resource conservation and reduces waste. The fish waste provides nutrients for the kangkung, while the kangkung helps to purify the water for the fish. This closed-loop system minimizes the need for external inputs, making it an environmentally friendly and cost-effective method of food production. Furthermore, Budikdamber is a highly adaptable system that can be easily implemented in various settings, from urban rooftops to rural backyards. It requires minimal space and can be managed with minimal effort, making it an ideal option for individuals and families seeking to grow their own food. In conclusion, Budikdamber is a promising approach to sustainable aquaculture that offers a multitude of benefits. It is a simple, efficient, and environmentally friendly system that can contribute to food security and promote a more sustainable way of life.
