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.

Abstract

Central Lombok Regency, especially in the Specific Economic Zone (SEZ) Mandalika apart from being a tourism area it is also one of the centers for seaweed cultivation in NTB Province, seaweed cultivation in the SEZ Mandalika, Central Lombok Regency currently still has several problems, one of which is business productivity which is still low. The low productivity of seaweed cultivation can be caused by inefficient allocation of inputs. The aims of this study were: 1) to analyze the factors that affect the production of seaweed aquaculture, 2) to analyze the level of efficiency of the production of seaweed aquaculture, and 3) to analyze the factors that influence the level of technical inefficiency of seaweed cultivation in SEZ Mandalika, Central Lombok Regency. This study uses a descriptive research method with a mixed method research approach. Collecting research data using survey techniques through interviews with respondents as many as 30 people who were taken by accidental sampling. Analysis of the data in this study using the method of Cobb-Douglas stochastic frontier production function to measure the level of production efficiency of seaweed cultivation in SEZ Mandalika, Central Lombok Regency. The results of this study indicate that seaweed production is significantly influenced by the variables of area, seeds, and labour. The level of production efficiency of seaweed cultivation is efficient with a production efficiency value of 0.861. Then the factors that affect the technical inefficiency of seaweed cultivation in Central Lombok Regency include level of education and dummy farmer groups.
