BARITO ALIMUDDIN: Respons Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis Jacq.) Terhadap Komposisi Media Tanam dan Pemberian Pupuk Hayati Cair di Pre Nursery, dibimbing oleh CHAIRANI HANUM dan ROSITA SIPAYUNG.
Penelitian ini bertujuan untuk mempelajari respons pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) pada beberapa komposisi media tanam dan pemberian pupuk hayati cair di pre nursery. Penelitian ini dilakukan di lahan percobaan Fakultas Pertanian, Universitas Sumatera Utara, Medan (25 m dpl) pada bulan April sampai Juli 2016. Metode percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor perlakuan yaitu komposisi media tanam (M1 : Top Soil , M2 : Top soil + Serat kelapa sawit ( 1 : 1 ), M3 : Top soil + TKKS ( 1 : 1 ), M4 : Top soil + Sludge ( 1 : 1 ), M5 : Top soil + Serat Kelapa Sawit + TKKS + Sludge ( 1 : 1 : 1 : 1 ) dan pupuk hayati cair (0, 5, 10 ml/liter air).
Hasil penelitian menunjukkan bahwa perlakuan pemberian pupuk hayati cair berpengaruh tidak nyata terhadap semua parameter yaitu tinggi tanaman, diameter batang, jumlah daun, total luas daun, volume akar, bobot basah tajuk, bobot basah akar, bobot kering tajuk, dan bobot kering akar. Perlakuan komposisi media tanam berpengaruh nyata terhadap tinggi tanaman pada 6-14 MST, jumlah daun 8-14 MST, diameter batang 8-14 MST, total luas daun, volume akar, bobot basah tajuk, bobot basah akar, bobot kering tajuk, dan bobot kering akar. Interaksi antara kedua perlakuan berpengaruh nyata terhadap terhadap tinggi tanaman pada 6-14 MST, jumlah daun 6-14 MST, diameter batang 6-14 MST, total luas daun, volume akar, bobot basah tajuk, , bobot kering tajuk, dan bobot kering akar. Komposisi media tanam terbaik yang menghasilkan jumlah daun terbanyak yaitu M3 : Top soil + TKKS ( 1 : 1 ).
Kata Kunci : Pupuk Hayati Cair, Komposisi Media Tanam, Kelapa Sawit.

ii ABSTRACT
BARITO ALIMUDDIN : The Growth Response of Oil Palm Seedlings (Elaeis guineensis Jacq.) of composition planting media and liquid biofertilizer in Pre Nursery. Guided by CHAIRANI HANUM and ROSITA SIPAYUNG.
The objective of this research was to study the growth of oil palm seedlings at Composition planting media and liquid biofertilizer in pre nursery. The research had been conducted on the land of Agriculture Faculty, Sumatera Utara University, Medan (25 m asl) in April until July 2016, by using Randomized Block Design with two factors . The first factor is composition planting media (top soil, top soil + fiber (1:1), top soil + Empty Palm Oil Fruit Bunches (EPOFB) (1:1), top soil + sludge (1:1) and top soil + fiber + Empty Palm Oil Fruit Bunches (EPOFB) + sludge (1:1:1:1) ) and the second factor is liquid biofertilizer (0, 5, and 10 ml/litre of water)
The result showed that the treatment of giving liquid biofertilizer had no significant effect on the all of parameters i.e. plant’s height, steem’s diameter, number of leaves, total leaf area, wet shoot weight, wet root weight, dry shoot weight, dry root weight, and the root volume. The treatment of composition palm waste had significant effect on plant’s height at 6-14 weeks after planting, number of leaves at 8-14 weeks after planting, steem’s diameter at 8-14 weeks after planting, total leaf area, root volume, wet shoot weight, dry shoot weight, wet root weight, and dry root weight. The interaction of composition palm waste media and liquid biofertilizer had significant effect on palnt’s height at 6-14 weeks after planting, number of leaves at 6-14 weeks after planting, steem’s diameter at 6-14 weeks after planting, total leaf area, root volume, wet shoot weight, dry shoot weight, and dry root weight. Media composition M3 (top soil + Empty Palm Oil Fruit Bunches (EPOFB) (1:1) gave the best results throught the the highest value number of leaves.
