Abstract

Kepiting bakau merupakan sumber nutrisi dan penghasilan yang memiliki nilai gizi dan ekonomi yang tinggi. Namun, penangkapan yang tidak selektif berpotensi mengurangi ketersediaannya di habitat alami. Penelitian ini bertujuan untuk mengidentifikasi indeks kematangan gonad dan fekunditas kepiting lumpur di Kawasan Mangrove Kecamatan Setia Bakti Kabupaten Aceh Jaya. Metode penelitian yang digunakan adalah survei dengan menggunakan teknik purposive sampling. Pengumpulan data dilakukan pada Juli 2022. Parameter penelitian meliputi indeks kematangan gonad dan fekunditas (jumlah telur). Data dianalisis secara kuantitatif. Hasil penelitian menunjukkan bahwa pada Sampel 1 diperoleh 1012 telur, Sampel 2 sejumlah 2003 telur, dan Sampel 3 sebanyak 2620 telur. Dengan demikian, dapat disimpulkan bahwa indeks kematangan gonad kepiting lumpur berkisar antara 7.16- 9.12%. Selain itu, terdapat variasi jumlah telur pada setiap sampel dengan jumlah telur tertinggi tercatat pada Sampel 3.

Abstract

The Control of Culex sp. using synthetic larvicides is harmful to the environment and human health. Biolarvicide from red shoot leaves (Syzygium myrtifolium) is a safe alternative for the environment and human health. This study aims to determine the effect of Syzygium myrtifolium leaves extract with ethanol solvent and water solvent on larval mortality and the LC50 values of these extracts. ANOVA test results (α = 0.05) on the mortality of Culex sp. larvae exposed to the ethanol extract and aqueous extract of S. myrtifolium leaves consecutively showed F-calculated (287)>F-tabulated (3,11) and F-calculated (153)>F-tabulated (3, 11). The treatment of S. myrtifolium leaves extract with ethanol and water solvents had a significant effect on the mortality of Culex sp. larvae. The LC50 value of the ethanol extract and the aqueous extract of S. myrtifolium leaves are 1659 ppm and was 2053.7 ppm. It can be concluded that S. myrtifolium leaves extracts with ethanol solvent and water solvent have an effect on the mortality of Culex sp. larvae, but are not yet effective as biolarvicide
