Common carp (Cyprinus carpio L.) is one of the widely cultivated fishes in Indonesia. Utilization of organic waste from the traditional market such as chicken intestines, corn husk, and water spinach stems into artificial feed for carp (Cyprinus carpio L.) var. Majalaya is discussed in this study. Protein content was made different to find the optimum level indicated by the better fish' absolute weight growth and feed efficiency. Commercial feed was used as a positive control to see opportunities for this artificial feed as an alternative that can reduce the cost of carp farming. Our study showed that this artificial feed with a protein content up to 30% (PB30) resulted in similar growth rate of body weight and feed efficiency compared to the control, yet better than PB26 and PB34. Therefore, this artificial feed presents a huge opportunity as an alternative solution to reduce the cost of carp farm production.
