This study aims to (1) the effect of type of waste on the performance of oil palm seeds (2) get the best incubation time to obtain good quality compost and its effect on the performance of seeds (3) get a good composition of the media to get the performance of both oil palm seedlings and its influence terhdap Ultisol physical properties, and (4) the effect of interaction between the type of waste, a long incubation, and the composition of the planting medium terhdap the performance of oil palm seedlings and Ultisol physical properties. The experiment was conducted in Palm Nursery Polytechnic Lampung from July 2009 until April 2010., Designed in factorial randomized block design. The treatments consisted of 3 (three) factors. The first factor is the type of waste consisting of sugar cane waste (bagase) and empty fruit bunches (Tankos) palm oil. The second factor is the length of incubation of waste, consisting of 2 (two) and 3 (three) weeks. Factors to 3 (three) is the composition of media, namely: 1 (compost): 4 (ground); 1 (compost): 5 soil, and 1 (sand): 4 (ground) as a control. Each treatment was replicated 3 (three) times, each experimental unit consisted of two seeds. The results showed that the sugar agro waste (bagasse) effect on plant height is better than empty fruit bunches Palm Oil (Tankos); waste Incubation period 3 weeks performed better on the character of dry weight, ratio of crown root and seedling growth rate; Bagas incubated 3 weeks influential The best in plant height; media composition had no effect on the growth characteristics of oil palmseedlings in the main nursery. Keywords: Oil Palm Seedlings, bagase, empty fruit bunches palm oil, incubation periode, and ultisol.

Pengaruh Bahan Organik, Pupuk P, dan Bakteri Pelarut Phosfat Terhadap Keragaan Tanaman Kelapa Sawit pada Ultisol Dewi Riniarti; Any Kusumastuti; Bambang Utoyo

This study was aims to determine the effect of organic matter kind, phosphate fertilizers, phosphate solubilizing bacteri, and an interaction effect between type of organic matter with phosphate fertilizers, and phosphate solubilizing bacteri on vigour of oil palm at ultisol. The study was designed as a factorial in a randomized block design and each treatment was repeated 3 (three) times. The treatment consisted of 3 (three) factors. First factor were kind of organic matter: bagase and empty fruit bunches of oil palm, and without organic matter; second factor were Phospate fertilizer consisted of 45 grams of P2O5 per tree (the recommended dose) or 125 g SP-36 and 56.25 g per tree (125% recommended dose) or 156.25gSP-36; and third factor were with and without of posphat solubilizing bacteri. The results showed that: the organic material bagasse provided vegetative characters (leaf number, petiole length, leaf angle, leaf chlorophyll content, and in the number of leaves) of oil palm plantations in the Ultisol was better than empty fruit bunches of oil palm plantations in ultisol, and empty fruit bunches of palm oil gave the generative character (the number of female flowers, sex ratio) on oil palm plantations in the Ultisol better than bagasse. Key words: organic matter, phosphate fertilizer, phosphate solubilizing bacteria,vigour of oil palm before producted, and ultisol.

Bibit kelapa sawit di pembibitan utama membutuhkan air sekitar 2 l/hari/tanaman. Hal ini menimbulkan kendala dalam penyediaan air pada musim kemarau dan daerah dengan tingkat curah hujan yang rendah sehingga diperlukan upaya mengurangi kehilangan air akibat penguapan. Penelitian ini bertujuan untuk mendapatkan jenis mulsa organik terbaik pada pembibitan utama kelapa sawit, mendapatkan volume penyiraman terbaik pada pembibitan utama kelapa sawit dan mendapatkan interaksi terbaik antara jenis mulsa dan volume penyiraman pada pembibitan utama kelapa sawit. Percobaan lapangan telah dilakukan pada Juli 2017 hingga Desember 2017 dengan rancangan acak kelompok faktorial. Faktor pertama yaitu jenis mulsa organik yang terdiri atas empat taraf: tanpa mulsa (M0), mulsa jerami padi (M1), mulsa sekam padi (M2), dan mulsa tandan kosong kelapa sawit (M3). Faktor kedua yaitu volume pemberian air irigasi yang terdiri atas dua taraf, yaitu pemberian air 1 l/hari/tanaman (I1) dan pemberian air 2 l/hari/tanaman (I2). Satuan pengamatan terdiri atas tiga bibit kelapa sawit dalam polibag untuk tiap kombinasi perlakuan. Hasil penelitian menunjukkan bahwa pemberian mulsa organik belum mampu meningkatkan pertumbuhan bibit kelapa sawit di pembibitan utama. Pertumbuhan bibit kelapa sawit terbaik dicapai dengan volume penyiraman 2 l/polibag/hari. Perlakuan kombinasi terbaik adalah mulsa tandan kosong kelapa sawit dan volume penyiraman 2 l/polibag/hari yang memberikan pengaruh terbaik pada kelembaban media tanam di pembibitan utama.
