Abstract

Estimasi parameter model regresi probit dapat dilakukan dengan menggunakan metode Maximum Likelihood Estimation (MLE). Namun, metode MLE tidak dapat dipakai apabila dalam data mengandung pemisahan (separation) baik pemisahan sempurna (complete separation) maupun pemisahan tidak sempurna (quasi-complete separation) karena mengakibatkan hasil estimasi dengan metode MLE tidak konvergen. Salah satu upaya yang dapat dilakukan untuk mengatasi hal ini adalah dengan menggunakan pendekatan prosedur Firth yang pertama kali diusulkan oleh Firth (1993). Penelitian ini menggunakan data sekunder pemberian kredit oleh pemerintah terhadap petani rumput laut di Kabupaten Kupang dengan tujuh variabel independen. Pada pemeriksaan awal ditemukan bahwa data tersebut mengandung pemisahan kurang sempurna yang mengakibatkan estimasi parameter bersifat divergen. Setelah ditangani dengan pendekatan prosedur Firth, diperoleh estimasi parameter yang bersifat konvergen

Lamongan regency is one of the minapolitan region in East Java Province, especially at Glagah district, Jatirenggo village which becomes the minapolist, with one of the superior commodities is whiteleg shrimp. The development of a certain village can be determined by village developing index or IDM which consists of three categories, they are left behind, developing, and advance village. Jatirenggo village has a village developing index (IDM) of 0.6080 which classified as developing category or category 2. Thus, in order to increase its status, the welfare of its people need to be considered. Whiteleg shrimp pond aquaculture can be one of the effort to increase the income of Jatirenggo’s. This study aims to analyze the sustainability of whiteleg shrimp aquaculture activity in Jatirenggo village according to ecology, socio-economic, technology-infrastructure, and institutional dimension. The used method was MDS Rapfish. The results showed that the whiteleg shrimp aquaculture in Jatirenggo village is classified as sustainable, or it means the situation in Jatirenggo village is suitable for a successful aquaculture. Thus, it can be expected to increase the income of the farmers.

Abstract

As one of the efforts to increase production of catfish culture, the Government of Tuban Regency launched the establishment of The Integrated Catfish Cultivation Center Area (ICACA) in Merakurak Sub-District in 2018. The existence of ICACA makes the program to increase catfish aquaculture more coordinated and increase production of catfish cultivation in Tuban Regency. ICCCA not only has an impact on the aquaculture business in Merakurak District, but also in other sub-districts in Tuban Regency. However, studies that explore the impact of ICACA on aquaculture in other areas are rarely reported. This study analyzes the impact of the existence of ICACA on cultivation business in Tuban District in Tuban Regency. This study uses a descriptive method with a mixed method approach (qualitative and quantitative). The results of this study indicate the factors that are the impact of ICACA in Merakurak District on the development of catfish cultivation in Tuban District. Based on the analysis carried out in this study, the implementation of ICACA in Tuban Regency, especially related to the effect of ICACA on catfish cultivation in Tuban District, needs to be directed to the application of sustainable aquaculture based on the empowerment of local community groups.
