Abstract

The high productivity and quality of the harvested prawn are the main objectives of the intensive giant freshwater prawn (GFP) culture. Therefore, the breeding program to create a superior strain of the prawn has been conducted in several countries to support prawn farming. The purpose of this study was to evaluate the productivity and female reproductive performance of the GFP superior strains, namely the selected GI Macro (GI) and Siratu (SR) in the three farming conditions. The GI has resulted from an individual selection program based on standard length and maturation level characters. The multi-location test was conducted in the grow-out phase for 90 days at the three locations based on altitude, namely low-lands (in Subang, 10-25 m above the sea level, asl), medium-lands (in Ciamis, 70-100 m asl), high-lands (in Kuningan, 700-800 m asl). The growth characters consisting of total length/TL, standard length/SL, and body weight/BB of GI and SR were not significantly different, both on the Low, medium, and high lands ponds.  The survival rate of the GI (87,3±7.26%) was significantly higher than the SR (71.0±0.08%) in the medium-land pond.  In the high-lands pond, the survival rate of the SR (72.33±0.32%) was significantly higher than the GI (55.8±6.27%). Meanwhile, the productivity and percentage of the gravid female in the low-lands pond were not significantly different. The data suggested that the selected GI Macro is a location-specific genotype, more suitable to be cultured in the low and moderate-lands pond with warm temperature characteristics. Keywords: freshwater prawn, growth, multi-location, reproduction

Abstract

This study examines the effects of entrepreneurship education, income expectations, and family environment on students' entrepreneurial interest at a private college in Jakarta. A quantitative approach was employed, with data collected through a questionnaire distributed via Google Forms. The population comprised students from the 2020, 2021, and 2022 cohorts at the same institution who had completed entrepreneurship courses. A sample of 100 respondents was analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS version 4.1.0.1. The findings indicate that entrepreneurship education has a direct positive effect on entrepreneurial interest, while income expectations show no significant effect. In contrast, the family environment demonstrates a direct effect on entrepreneurial interest. From a practical standpoint, higher education institutions should strengthen experiential entrepreneurship curricula and foster supportive family engagement through workshops or parent outreach programs. Policymakers may consider integrating family-based entrepreneurial mentoring into formal education. Educators should not overemphasize income expectations when promoting entrepreneurship, as financial motives alone do not significantly drive student interest.
