Artificial Bee Colony — Based for dietary recommendation in daily nutrition requirements

Healthy lifestyle is an important requirement for people, which is obtained from balanced nutrition. Imbalanced nutrition increases risk of health problems. Balanced nutrition means the difference between nutrition needed and nutrition intake must be as minimum as possible. The condition in Indonesian, many people consume food with high carbohydrate; whereas nutrition consists of protein, carbohydrate, and fat. That nutrition obtains from five foods category, namely: main dish (MP), vegetable side dish (LN), meat (LH), vegetable (SY), and fruit (BH). Therefore, it needs a system to provide a suggestion for balanced nutrition. This research used Artificial Bee Colony (ABC) to obtain optimal nutrition, which contains five dimensions (MP, LH, LN, SY, BH). These dimension and variable are represented as food source, which will be optimized by bees. These bees are divided into employee bee (BN), onlooker bee (SN), and scout bee. BN will produce new food source, where if new food source has a better solution, it will replace the old one. SN performers based on the fitness value of each food source; if the food source has high probability, SN will produce new food source. While scout bee will determine a new food source, if the number of trials for releasing a food source is equal to the value of “limit”. The performance of ABC evaluated using twelve data of men and female. The result shows that ABC achieve 99.90% in giving a recommendation for portion and type of foods a day.
