Respons Pertumbuhan Bibit Kelapa Sawit pada Media Tanam Kompos Limbah Organik Perkebunan

Abstract

The underutilization of oil palm midrib and fruit fiber, which are abundant in oil palm plantations and the manufacturing field, encourages them to be converted into more valuable products. The goals of this experiment were to create planting media out of oil palm midrib and fiber, as well as to find the best compost formulation of oil palm midrib (MR) and fiber (FF) for seedlings in prenursery. The treatments were arranged in a non-factorial completed randomized design, with 15 treatments. The treatments are  : P0 (100% top soil), P1 (50% MR + 50% CW + Activator 1), P2 (50% MR + 50% CW + Activator II), P3 (50% MR + 50% CW + POME); P4 (100% MR + Activator II); P5 (100% MR + LCPKS), M1 (50% FF : 50% CW + Activator 1); M2 (50%  FF : 50% CW + Activator II); M3 (50%  FF : 50% CW + POME); M4 (100%  FF + Activator II); M5 (100%  FF + POME), PM1 (50% MR-FF + 50% CW + Activator I); PM2 (MR-FF + 50% CW + POME); PM4 (100% MR-FF + Activator II); PM5 (100% MR-FF + POME). The results showed that oil palm midrib and fiber composting media significantly affected morphological responses of oil palm seed growth (plant height, stem diameter and leaf area seedlings), and physiological responses of oil palm seed growth (biomass and stomata conductance). These results could be promoted as a new challenge to formulating the lignocellulose-based planting media.Pemanfaatan yang terbatas terhadap produk samping berupa pelepah dan serat buah kelapa sawit, yang tersedia melimpah di perkebunan dan pabrik pengolahan kelapa sawit, mendorong penggunaannya menjadi produk yang lebih bernilai. Tujuan dari penelitian ini adalah untuk membuat media tanam dari pelepah dan serat kelapa sawit, serta untuk mendapatkan formulasi kompos pelepah kelapa sawit (MR) dan serat (FF) terbaik untuk pembibitan di prenursery. Perlakuan disusun dalam rancangan acak lengkap non faktorial, dengan 15 perlakuan. Perlakuannya adalah : P0 (100% top soil), P1 (50% MR + 50% CW + Activator 1), P2 (50% MR + 50% CW + Activator II), P3 (50% MR + 50% CW + POME); P4 (100% MR + Aktivator II); P5 (100% MR + LCPKS), M1 (50% FF : 50% CW + Aktivator 1); M2 (50% FF : 50% CW + Aktivator II); M3 (50% FF : 50% CW + POME); M4 (100% FF + Aktivator II); M5 (100% FF + POME), PM1 (50% MR-FF + 50% CW + Aktivator I); PM2 (MR-FF + 50% CW + POME); PM4 (100% MR-FF + Aktivator II); PM5 (100% MR-FF + POME). Hasil penelitian menunjukkan bahwa media tanam kompos pelepah dan serat berpengaruh nyata terhadap respons morfologi pertumbuhan benih kelapa sawit (tinggi tanaman, diameter batang dan luas daun bibit), dan respons fisiologis pertumbuhan benih kelapa sawit (biomassa dan jumlah stomata). Hasil ini merupakan tantangan baru untuk membuat formulasi media tanam berbasis limbah lignoselulosa
