Abstract. The objective of this research was to describe broiler farmers' behavior including knowledge level, attitude, antibiotic practice and analysis of the antibiotic content in broiler chicken commercial feed. Survey method was conducted with purposive and random sampling, applying Nomogram Harry King to determine total sample. Ninety-six farmers met the sampling criteria, comprising 33 respondent farmers along with survey and feed sampling in each farmer. Interview and questioner result on knowledge level and farmers' attitude and observation on farmers practice in administering antibiotic were subject to description in data tabulation. Laboratory analysis result using Bioassay method on antibiotic content in feed was described in data tabulation. Broiler farmers in Pengadegan municipality, Purbalingga Regency generally showed moderate knowledge level (60% above average, 40% under average). Farmers with supportive attitude on good antibiotic administration was 48.48%, while those less supportive reached 51.52%. Farmers' level of obedience in proper antibiotic practices was only 21.21%, almost half (45.45%) defiled the proper antibiotic administration. Most farmers (96.97%) used commercial feed containing AGP (Antibiotic Growth Promoter) not recommended by government, namely penicillin, kanamycin, erythromycin andoxytetracycline. Farmer administered overdosed antibiotic as growth booster, anti-stress, disease control and medication. Research concluded that most broiler farmers violated the rules of antibiotic practices, in which overdosed content was administered to stimulate growth, anti-stress, disease control and medication. Antibiotic as growth booster was contained in feed. Commercial broiler feed (complete feed) contained four types of antibiotic, namely penicillin, kanamycin, erythromycin andoxytetracycline.
