      Abstract
      Nanas (Ananas comosus L. Merr) merupakan komoditas hortikultura unggulan bernilai ekonomi tinggi yang berperan penting dalam industri pengolahan dan ekspor. Dalam upaya mendukung keberlanjutan produksi, limbah cair IPAL berkapasitas debit hilir ±14 m3 hari-1 berpotensi dimanfaatkan sebagai sumber irigasi alternatif. Penelitian ini bertujuan menganalisis perbandingan pengaruh sumber air irigasi dari kolam IPAL dan sumur bor terhadap pertumbuhan, produksi, dan kualitas buah nanas GP3. Penelitian dilaksanakan pada Juli–November 2025 di PT Great Giant Pineapple, Terbanggi Besar, Lampung. Hasil menunjukkan bahwa penggunaan air irigasi dari kolam IPAL tidak memberikan perbedaan nyata terhadap pertumbuhan vegetatif dan produksi dibandingkan kontrol. Perlakuan kolam 15 IPAL nanas yang terkontaminasi Dickeya sp. (B) secara konsisten menunjukkan insidensi dan severitas penyakit tertinggi dibandingkan kontrol sumur bor (A) dan kolam 13 IPAL tapioka (C). Insidensi layu Dickeya pada plot generatif sebesar 15,87% (A: 12,60%; C: 12,73%) dan vegetatif 29,32% (A: 11,57%; C: 25,75%). Insidensi penyakit buah rotten 20,00% (A dan C: 0,00%) dengan severitas 15,00% (A dan C: 0,00%), serta penurunan kualitas ditunjukkan dengan peningkatan buah grade <1T 25,82% (A: 7,29%; C: 6,60%) dan buah mentah 20,00% (A: 15,00%; C: 0,00%). Penggunaan air terkontaminasi bakteri meningkatkan serangan penyakit dan menurunkan mutu buah, pemanfaatan air kolam IPAL sebagai irigasi perlu dikelola agar mendukung produksi nanas optimal.
       
      Pineapple (Ananas comosus L. Merr) is a superior horticultural commodity with high economic value and an important role in processing and export industries. To support sustainability, wastewater from a wastewater treatment plant (WWTP) with a downstream discharge capacity of ±14 m³ day-1 has potential as an alternative irrigation source. This study analyzed the effect of irrigation water from WWTP ponds and drilled wells on the growth, production, and fruit quality of GP3 pineapple. The study was conducted in July–November 2025 at PT Great Giant Pineapple, Terbanggi Besar, Lampung. Results showed WWTP pond irrigation had no significant difference in vegetative growth and production compared to the control. However, pond 15 WWTP pineapple contaminated with Dickeya sp. (B) consistently showed the highest disease incidence and severity compared to drilled well control (A) and pond 13 tapioca WWTP (C). Dickeya wilt incidence in generative plots was 15.87% (A: 12.60%; C: 12.73%) and vegetative 29.32% (A: 11.57%; C: 25.75%). Rotten fruit incidence was 20.00% (A, C: 0.00%) with 15.00% severity (A, C: 0.00%). Quality decline was shown by fruit grade <1T 25.82% (A: 7.29%; C: 6.60%) and unripe fruit 20.00% (A: 15.00%; C: 0.00%). Bacterial contamination increased disease and reduced fruit quality also WWTP water use must be properly managed.
