N2  - Keanekaragaman serangga air merupakan bioindikator dalam ekosistem pertanian karena  mencerminkan  kesehatan  perairan,  terutama  di  lahan  sawah  organik  dan anorganik.  Pertanian  organik  yang  menggunakan  bahan  alami  cenderung meningkatkan  keanekaragaman  hayati,  sedangkan  pertanian  anorganik  dapat menurunkannya  akibat  penggunaan  pestisida  dan  pupuk  kimia.  Penelitian  ini bertujuan  menganalisis  keanekaragaman,  dominansi,  kemerataan,  dan  faktor abiotik  yang  memengaruhi  kelimpahan  serangga  air  di  lahan  organik  dan anorganik di Desa Tulung Agung, Kecamatan Gadingrejo, Kabupaten Pringsewu, Lampung,  pada  Desember  2024?Februari  2025.  Hasil  penelitian  menunjukkan keanekaragaman serangga air lebih tinggi pada lahan organik (H? 2,3386), dengan dominansi rendah (D = 0,058) dan kemerataan tinggi (E = 0,9411), sedangkan di lahan anorganik keanekaragaman lebih rendah (H? 0,9743), dominansi sedang (D = 0,5188), dan kemerataan rendah  (E = 0,3312).  Faktor fisika?kimia air di lahan organik  tidak  berpengaruh  signifikan,  sementara  di  lahan  anorganik  terdapat korelasi yang kuat dan Signifikan (r = 0,905; p = 0,035).

The diversity of aquatic insects serves as a bioindicator in agricultural ecosystems because it reflects water quality, particularly in organic and conventional (inorganic) rice fields. Organic farming, which utilizes natural materials, tends to enhance biodiversity, while conventional farming may reduce it due to the use of chemical pesticides and fertilizers. This study aims to analyze the diversity, dominance, evenness, and abiotic factors influencing the abundance of aquatic insects in organic and conventional rice fields in Tulung Agung Village, Gadingrejo Subdistrict, Pringsewu Regency, Lampung, from December 2024 to February 2025. The results showed that aquatic insect diversity was higher in organic fields (H? = 2.3386), with low dominance (D = 0.058) and high evenness (E = 0.9411). In contrast, conventional fields exhibited lower diversity (H? = 0.9743), moderate dominance (D = 0.5188), and low evenness (E = 0.3312). Physicochemical factors in organic fields had no significant effect on aquatic insect abundance, while in conventional fields, a strong and significant correlation was found (r = 0.905; p = 0.035).
