dc.description.abstract | Pemerintah Indonesia pada tahun 2006 menargetkan 10% dari total
kebutuhan bahan bakar minyak (BBM) nasional sebesar 40.1 jt/kl, dapat dipenuhi
dari bahan bakar nabati (BBN). Ki pahang (Pongamia pinnata (L.) Pierre)
merupakan salah tanaman yang berpotensi untuk dikembangkan sebagai sumber
BBN. Kelebihan tanaman ini sebagai sumber BBN adalah tidak bersaing dengan
penggunaaan lain dan sifatnya yang dapat menfiksasi nitrogen karena termasuk
famili Leguminaceae.
Potensi tanaman Ki pahang menghasilkan biodiesel mencapai 25 ton biji
/ha/th, atau setara dengan 7,3 ribu liter minyak/ha/th lebih tinggi dibandingkan
dengan jarak pagar IP3-P yang dipredikasi menghasilkan biji sebesar 8-9 ton
biji/ha/th atau setara dengan 2,6 ribu liter minyak/ha/th. Penelitian tanaman Ki
pahang di Indonesia sampai saat ini masih sedikit dilakukan. Penelitian ini
bertujuan untuk mempelajari pengaruh ukuran dan sumber benih terhadap
perkecambahan benih, serta media yang dapat mendukung pertumbuhan bibit
tanaman Ki pahang.
Penelitian dilaksanakan pada bulan September 2010 sampai dengan bulan
Februari 2011. Lokasi penelitian di rumah kaca Cikabayan, Departemen
Agronomi dan Hortikultura Institut Pertanian Bogor (IPB). Penelitian ini terdiri
dari dua percobaan. Percobaan satu yaitu pengaruh sumber dan ukuran benih
terhadap perkecambahan benih Ki pahang, dengan menggunakan rancangan acak
kelompok (RAK) terdiri dari dua faktor. Faktor pertama yaitu sumber benih yang
berasal dari Taman Nasional (TN) Ujung Kulon (S1) dan Kebun Raya Bogor
(S2). Faktor kedua yaitu ukuran benih yang terdiri dari benih besar >15 mm
(>1.5 gr) (U1), dan benih kecil dengan ukuran �����15 mm (�����1.5 gr) (U2), sehingga
terdapat empat kombinasi perlakuan. Percobaan dua mempelajari pengaruh
ukuran benih dan media tanam terhadap pertumbuhan bibit Ki pahang.
Rancangan percobaan ini adalah rancangan petak terbagi (split plot design).
Sebagai petak utama yaitu bibit yang berasal dari benih ukuran besar yaitu >15
mm (>1,5 gr) (U1), dan bibit yang berasal dari benih kecil �����15 mm (�����1,5 gr)
(U2), sedangkan sebagai anak petak adalah media tanam terdiri dari :1) M1:
media tanah topsoil; 2) M2: media tanah topsoil dan pasir (1:1); 3) M3: media
tanah topsoil dan arang sekam (1:1). | id |
dc.description.abstract | In 2006 the Indonesian government was targeting 10% of total national fuel
demand (40.1 milion/kl/year) would be fulfilled by biofuel in the year 2025.
Ki Pahang is one of potential source biodiesel which has been developed in India,
Bangladesh, Philippines and Australia. The species belongs to Leguminaceae
family that fixes nitrogen from the air. The biodiesel production of the species is
up to 25 tons seed/ha/year, equivalent to 7.3 thousand liters oil/ha/year, higher
than the third generation of Jatropha IP-3P estimated produce of 8-9 tons
seed/ha/year or equal to 2.6 thousand liters oil/ha/year. However, research on the
species in Indonesia is very scarce. The objective of this research is to study the
effect of seed size and source on viability, and to investigate the suitable nursery
planting media at the seedling stage.
The experiment was conducted in September 2010 to February 2011,
in Cikabayan greenhouse belongs to Department of Agronomy and Horticulture,
Bogor Agricultural University (IPB). This research consisted of two experiments;
the first experiment was to study the effect of seed size and source on seed
viability and vigor. The experiment was arranged in (RBD) randomized block
design with two factors. The first factor was seed source, i.e. (UKP)
the Ujung Kulon National Park and (BBG) the Bogor Botanical Garden. The
second factor was seed size that consists of large seeds >15 mm(>1.5 g) and
small seeds ≤ 15 mm (≤ 1.5 g). The second experiment was to study the effect of
seed size and planting media on seedling growth of Ki Pahang. The experiment
was arranged in split plot design with the main plot was
seedlings derived from large seeds > 15 mm (> 1.5 g), and from small seeds ≤ 15
mm (≤1.5 g). The sub plot was plamting media consisted of: 1) topsoil ; 2)
topsoil and sand (1:1); 3) topsoil and rice husk charcoal (1:1).
The result showed that the effect of interaction between seed size and
seed source was significant on germination percentage but not on germination
speed. The germinataion of small seed of UKP was 84% similar to those of large
seed (76%) of the same source, but significantly higher than germination
percentage of BBG seeds regardless the seed size (73% of large seed size and
65% of small). Germination speed of seed from UKP was higher (6,51 %/etmal)
than those from BBG (5,36% NG/etmal).
Planting media significantly affect seedling growth. The mixture of soil and
sand (1:1) and soil and rice husk charcoal (1:1) were the suitable planting media
for Pongamia seedlings. | id |
