      Abstract
      AKMAL MUSTIKA RAHMAN. Evaluasi Pengaruh Berbagai Dosis Abu Boiler terhadap Pertumbuhan Bibit Kelapa Sawit pada Media Tanam Sulfat Masam. Dibimbing oleh IIS PURNAMAWATI. Tanah sulfat masam memiliki kendala utama pH rendah dan toksisitas Al serta Fe yang menghambat pertumbuhan kelapa sawit. Penelitian ini bertujuan mengevaluasi pengaruh abu boiler terhadap pertumbuhan bibit dan kemampuannya dalam meningkatkan pH tanah. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) faktorial dengan dua faktor, yaitu jenis media tanam (tanah sulfat masam dan tanah kontrol) dan dosis abu boiler (0, 100, 200, dan 300 g per polibag). Parameter pertumbuhan vegetatif diamati selama 10 minggu. Hasil penelitian menunjukkan bahwa aplikasi abu boiler secara nyata meningkatkan tinggi tanaman. Temuan utama menunjukkan bahwa penggunaan media campuran sulfat masam dengan topsoil dan penambahan abu boiler tidak memberikan dampak negatif terhadap pertumbuhan bibit kelapa sawit. Abu boiler efektif meningkatkan pH tanah sulfat masam, sehingga menurunkan toksisitas logam. Penelitian ini menyimpulkan bahwa optimasi dosis abu boiler berperan penting dalam mendukung pertumbuhan bibit dan memperbaiki kualitas tanah di pembibitan kelapa sawit.
       
      Acid sulfate soil presents significant constraints for oil palm cultivation, characterized by low pH and high toxicity of aluminum (Al³?) and iron (Fe²?). This study aimed to evaluate the effect of boiler ash on the growth of oil palm seedlings and its capacity to increase soil pH. The research employed a factorial randomized complete block design (RCBD) with two factors: growing media (acid sulfate soil and control soil) and boiler ash dosages (0, 100, 200, and 300 g per polybag). Vegetative growth parameters were observed over ten weeks. The results demonstrated that the application of boiler ash, significantly increased plant height. The study found that the use of a mixed growing media of acid sulfate soil with topsoil, combined with boiler ash application, had no negative impact on seedling growth. Furthermore, boiler ash proved effective in raising the soil pH, thereby reducing metal toxicity. This research concludes that optimizing boiler ash dosage is crucial for supporting seedling development and improving soil quality in oil palm nurseries.
