ABSTRAKPenelitian dilakukan dengan tujuan untuk menganalisis penerapan subsistem agribisnis usaha ternak sapi potong di Jawa Tengah. Lokasi penelitian ditentukan secara purposive sampling berdasarkan Location Quotion (LQ) yaitu Kabupaten Rembang, Blora, Grobogan, Boyolali dan Wonogiri. Responden peternak ditentukan dengan metode quota sampling, setiap kabupaten diambil 40 responden. Data dianalisis dengan Structural Equation Model (SEM). Hasil penelitian menunjukkan bahwa subsistem agribisnis diterapkan dengan indeks cukup, yakni score untuk subsistem sarana produksi 0,693; proses produksi 0,721; pasca panen 0,684; pemasaran 0,626 dan Lembaga Pendukung Agribisnis adalah 0,691. Analisis menunjukkan bahwa model SEM adalah layak dengan nilai Chi-Square=0,952; RMSEA=0,000; Probabilitas=0,621 dan TL1=1,126. Analisis Critical Ratio (CR) menunjukkan bahwa subsistem agribisnis hulu berpengaruh terhadap proses produksi; subsistem proses produksi berpengaruh terhadap subsistem agribisnis hilir; subsistem agribisnis hilir berpengaruh terhadap pendapatan peternak, subsistem pemasaran berpengaruh terhadap subsistem agribisnis hilir dan Lembaga Pendukung Agribisnis berpengaruh terhadap subsistem agribisnis hilir dan pemasaran. Kesimpulan: penerapan subsistem agribisnis usaha sapi potong dilakukan dengan indeks penerapan cukup, setiap subsistem saling berhubungan dan berpengaruh terhadap penerapan agribisnis sapi potong.

ABSTRACTThe study aimed to analyze the implementation of subsystem agribusiness on the beef cattle farming in Central Java. Five districts (Rembang, Blora, Grobogan, Boyolali and Wonogiri) were purposively chosen based on the value of Location Quotient (LQ). The study was conducted using quota sampling method. Forty respondents of each district were chosen randomly using quota sampling. Data were analyzed through Structural Equation Model (SEM). The results showed that each subsystem agribusiness had adequate potential score. The score of 0.693, 0.721, 0.684, 0.626, and 0.691 were given for up-stream subsystem, on-farm, down-stream subsystem, marketing and supporting institution, respectively. The results showed that the SEM model was feasible with Chi-Square value=0.952; RMSEA=0.000; Probability =0.621 and TL1=1.126. The significant results of Critical Ratio (CR) were: up-stream subsystem to the on-farm agribusiness; on-farm subsystem to down-stream agribusiness; down-stream subsystem to the farmer's income; marketing subsystem to the up-stream agribusiness and Supporting Institution to the marketing subsystem and down-stream agribusiness. The conclusion of research indicated that the implementation of beef cattle subsystem agribusiness had adequate index and give positive effect to the beef cattle agribusiness.
