      Abstract
      Oil palm (Elaeis guineensis Jacq.) is a crop with high nutrient requirements; therefore, evaluating its nutrient status is essential to support optimal growth and productivity. This study aimed to evaluate the nutrient contents of the 9th, 17th, 25th, and 33rd fronds and to determine the most representative frond as the standard Leaf Sampling Unit (LSU). The research was conducted at Hatantiring Estate, PT Teguh Sempurna, using an observational approach. Leaf samples were analyzed for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) using the Kjeldahl, spectrophotometric, flame photometric, and Atomic Absorption Spectrophotometry (AAS) methods. The results indicated that N and P contents tended to decrease with increasing frond age, whereas K showed a fluctuating pattern, with the highest concentration observed in the 25th frond. Calcium content remained relatively stable across all frond positions, while Mg tended to decline in older fronds. Based on the distribution of nutrient contents and frond biomass, the 17th frond remained the most representative position for the LSU standard, whereas the 25th frond showed potential as an alternative.
       
      YUDA BAYU SETIAJI. Observasi Kadar Hara pada Daun Kelapa Sawit melalui Metode Leaf Sampling Unit (LSU). Dibimbing oleh AIDIL AZHAR. Kelapa sawit (Elaeis guineensis Jacq.) merupakan tanaman dengan kebutuhan unsur hara yang tinggi sehingga evaluasi status hara diperlukan untuk mendukung produktivitas. Penelitian ini bertujuan mengevaluasi kandungan unsur hara pada pelepah ke-9, ke-17, ke-25, dan ke-33 serta menentukan pelepah yang paling representatif sebagai standar leaf sampling unit (LSU). Penelitian dilaksanakan di Hatantiring Estate, PT Teguh Sempurna, menggunakan metode observasional. Sampel daun dianalisis untuk mengetahui kandungan nitrogen (N), fosfor (P), kalium (K), kalsium (Ca), dan magnesium (Mg) menggunakan metode Kjeldahl, spektrofotometri, flame photometer, dan Atomic Absorption Spectrophotometry (AAS). Hasil penelitian menunjukkan bahwa kandungan N dan P cenderung menurun seiring bertambahnya umur pelepah, K menunjukkan pola fluktuatif dengan nilai tertinggi pada pelepah ke-25, sedangkan Ca relatif stabil dan Mg cenderung menurun pada pelepah tua. Berdasarkan distribusi unsur hara dan biomassa, pelepah ke-17 tetap paling representatif sebagai standar LSU, sementara pelepah ke-25 berpotensi menjadi alternatif.
