Penelitian ini bertujuan untuk mengetahui efektivitas maskulinisasi lobster air tawar/LAT (Cherax quadricarinatus) dengan perendaman dalam larutan propolis, mengetahui konsentrasi propolis yang optimal untuk maskulinisasi, dan mengetahui pengaruh perendaman larva dalam larutan propolis terhadap sintasan dan pertumbuhan. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan perendaman dengan konsentrasi larutan propolis yang berbeda, yaitu konsentrasi 0 mikroliter/liter (kontrol), 20 mikroliter/liter, 40 mikroliter/liter, dan 60 mikroliter/liter. Analisis data menggunakan analisis sidik ragam (ANOVA) dan dilanjutkan dengan uji kisaran berganda Duncan (DMRT). Hasil penelitian menunjukkan bahwa perendaman larva LAT dalam larutan propolis tidak mempengaruhi persentase nisbah kelamin jantan, namun persentase nisbah kelamin jantan LAT cenderung meningkat seiring dengan peningkatan konsentrasi larutan propolis. Persentase nisbah kelamin jantan tertinggi diperoleh pada konsentrasi 60 mikroliter/liter sebesar 72,61±6,15% dan yang terendah diperoleh pada kontrol (0 mikroliter/liter) sebesar 54,12±9,51%, sedangkan pada konsentrasi 20 mikroliter/liter sebesar 62,11±5,57% dan pada konsentrasi 40 mikroliter/liter sebesar 67,19±8,26%. Konsentrasi larutan propolis yang optimal untuk maskulinisasi LAT adalah 60 mikroliter/liter. Perendaman larva LAT dalam larutan propolis tidak mempengaruhi sintasan dan pertumbuhan.

This research aimed to determine the effectiveness of the masculinization in freshwater crayfish (Cherax quadricarinatus) by immersion in a solution of propolis, to find the optimum concentration of propolis for masculinization, and to determine the effect of immersion in a solution of propolis on the survival rate and growth. This research used completely randomize design with 4 treatments of the difference concentrations of propolis, ie 0 microliter/liter (control), 20 microliter/liter, 40 microliter/liter, and 60 microliter/liter in triplicates. Data were analysed by using Analysis of Variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT). The result of this research showed that the percentage of male tends to increase by increasing the concentration of propolis, but analysis of variance showed no significant differences. The highest percentage of male was obtained at concentration 60 microliter/liter that was 72.61±6.15%, and the lowest percentage of male sex ratio was obtained by the control (0 microliter/liter) treatment that was 54.12±9.51%, whereas at the concentration 20 microliter/liter that was 62.11±5.57%, and at the concentration 40 microliter/liter that was 67.19±8.26%. The concentration 60 microliter/liter was suitable for masculinization of freshwater crayfish. Masculinization of freshwater crayfish by immersion in a solution of propolis did not affect the survival rate and growth.
