Abstract
East Lombok Regency is one of the centers for the development of aquaculture and the largest lobster seed producer in Indonesia. However, in terms of productivity, lobster cultivation is still relatively low due to the less optimal use of production factors and management in carrying out lobster rearing cultivation. The purpose of this study was to analyze the factors that affect the production of lobster rearing aquaculture and to analyze the level of technical efficiency and the factors that influence the technical inefficiency of lobster rearing aquaculture in East Lombok Regency. Descriptive research method was selected in this research. Cross section data was collected using a survey technique on 40 respondents who were selected by simple random sampling. The collected data was then analyzed using the Cobb-Douglas Stochastic Frontier production function with the Maximum Likelihood Estimator (MLE) method. The results showed that the production of lobster rearing aquaculture in East Lombok Regency was significantly influenced at the alpha level 5% by the variables of the number of cages, feed, number of family dependents and dummy species. The level of technical efficiency of lobster rearing cultivation is classified as efficient with a technical efficiency value of 0.94. Then the factors that affect the inefficiency of lobster rearing business in East Lombok Regency include age, education level and training dummy.

Summary
Metode penelitian deskriptif kuantitatif dan kualitatif digunakan sebagai metode pada penelitian (Sugiono, 2017). Fungsi produksi Cobb-Douglas stochastic frontier digunakan untuk menganalisis faktor-faktor yang mempengaruhi produksi lobster, tingkat efisiensi teknis dan faktor-faktor yang mempengaruhi inefisiensi teknis pada. Persamaan fungsi produksi Cobb-Douglas stochastic frontier analysis (SFA) dari usaha budidaya pembesaran lobster di Kabupaten. Kemudian untuk mengukur tingkat efisiensi teknis digunakan persamaan sebagai berikut (Coelli et al, 2005): TE. Kemudian model efek inefisiensi teknis oleh Coelli et al, (2005) digunakan untuk mengukur tingkat inefisiensi teknis usaha budidaya pembesaran lobster di Kabupaten Lombok Timur. Variabel ui sebagai efek dari inefisiensi teknis pada usaha budidaya pembesaran lobster diasumsikan terdistribusi setengah normal dan bebas dengan N (ui,σ2). Adapun persamaan efek inefisiensi teknis (ui) yang digunakan pada penelitian ini yaitu sebagai berikut: Ui=δ0+ δ1Z1+ δ2Z2+ δ3Z3 + δ4Z4+ δ5Z5 + ωi keterangan:. Nilai gamma (γ) diartikan sebagai besarnya kontribusi efek inefisiensi teknis terhadap efek residual total
