Abstract
Uncontrolled usage of pesticides can contaminate the environment such as water, soil, and air. This occurs because the residue of pesticides. One of them, organochlorine insecticides have widely used by farmers because it is persistent. This study aims to look at the effects caused by organochlorine insecticide endosulfan on hatchability of eggs tilapia (Oreochromis niloticus). This research was conducted CRD with 6 treatments and 4 replications. Concentrations of organochlorine endosulfan in treatment are determined based on the LC50. The treatment use organochlorine endosulfan at concentrations of 0.00395%, 0.00400%, 0.00405%, 0.00410% and 0.00415%. Then they observed for 4 days (96 hours). The data obtained and analyzed by ANOVA and followed by DNMRT (Duncan's New Multiple Range Test). The result showed organochlorine insecticide endosulfan significantly (p<0,05) affect hatchability of eggs tilapia (Oreochromis niloticus), but no significant effect on larval abnormalities. Hatchability of eggs tilapia (Oreochromis niloticus) and the highest larval abnormalities are found in P1 which is a control treatment. While the hatchability of eggs and larvae abnormalities lowest for the P6 treatment with concentrations of endosulfan treatment 0.00415%.Keywords: endosulfan, Tilapia (Oreochromis niloticus), hatchability

Summary
Kemajuan teknologi di bidang pertanian membuka peluang yang sangat besar bagi penggunaan pestisida di lapangan. Penggunaan insektisida ini juga memiliki dampak negatif terhadap manusia, hewan ternak, biota air, lingkungan, dan lain-lain.[3] Hal ini dapat terjadi karena residu bahan aktif pestisida yang tertinggal dan terbioakumulasi di dalam tanah dan air.[4]. Hal ini mengakibatkan ikan kejang-kejang.[10] Jika ikan ini dikonsumsi dalam jangka panjang oleh manusia maka dapat menimbulkan sel kanker, karena insektisida organoklorin endosulfan ini bersifat karsinogenik.[8]. Karacunan ikan dan biota air lainnya tidak hanya menyebabkan kelainan pertumbuhan yang mangakibatkan perubahan tingkah laku dan bentuk, yang selanjutnya dapat mengakibatkan terhambatnya perkembangan populasi ikan tersebut.[3]. Berdasarkan permasalahan yang telah diuraikan dilakukan penelitian yang bertujuan untuk melihat pengaruh insektisida organoklorin endosulfan terhadap daya tetas telur ikan nila (Oreochromis niloticus)
