Abstrak: The objective of this research was to evaluate ten (10) lines of new plant type (NTP) of rice. This research was conducted on April – August 2013 in Desa Sukajaya, Kelurahan Raja Basa Jaya, Kecamatan Raja Basa, Kota Bandar Lampung, Lampung. Postharvest observation was conducted in Postharvest Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University (IPB). A Randomized Complete Block Design with a factor and three replication were used in this experiment. Ten lines of rice that were used are IPB 158-F-1-2-1, IPB 158-F-7-1-1, IPB 159-F-14-3-1, IPB 159-F-15-1-1, IPB 160-F-3-1-1, IPB 160-F-4-2-1, IPB 160-F-7-3-1, IPB 160-F-36-1-1, IPB 161-F-1-2-1, IPB 161-F-6-1-1, Ciherang, and Mekongga. The result showed that IPB 161-F-6-1-1 line is the best line and has important characters of new plant type of rice such as medium number of productive tillers, low number of empty grains, high number of filling grains, high weight of 1000 grains, and high productivity. IPB 160-F-3-1-1 and IPB 160-F-4-2-1- could also potentially developed.

Abstrak: Rice is the main food commodities. The demand of rice increasing in line with growth of the population in Indonesia. Meanwhile, potential yield of new superior varieties (VUB) which has grown farmers have reached the optimum. Required assembling new varieties that have high yield potential and have a wide adaptability. The objective of this research were to evaluate potential yield of IPB New Plant Type of Rice (NPT) potential for hight yielding varieties in multilocation test and as part of the completeness data requirements for proposing varietie release. Research was done in Bojong Leles, Lebak, Banten from May until September 2011. The research was done using Randomized Complete Design Group (RKLT) by a single factor of genotypes or lines. Genotypes used were 10 IPB new plant type of rice promising lines there are IPB107-F-5-1-1, IPB107-F-65-3-1, IPB113-F-2-1-1, IPB115-F-3-2-1, IPB116-F-3-1-1, IPB116-F-44-1-1, IPB116-F-46-1-1, IPB117-F-1-3-1, IPB117-F-4-1-1, and IPB149-F-8-1-1 with 2 comparison variety, there are Ciherang and IR64. The research was repeated three replicates so that there are 36 units of the research. Each unit of the research were planted in a plot measuring 4 m x 5 m. Spacing used in these researchs was 2:1 legowo spacing (10 cm x 20 cm x 40 cm). The study further analyzed the F test on a real level 5%, if significantly different be followed by Dunnet t-test at 5% level. The results showed that lines tested showed an average yield lower up to the equivalent comparison varieties. Line IPB115-F-3-2-1 (6.38 tonnes / ha) is a line with the results closest comparison varieties. Some lines show a character who approached the character of NPT with important characteristics, low tillering capacity (8-13 tillers productive), large panicle and thick, number of grain filling a lot (200-250 grains/panicle), short growth duration (100-120 days), and 1000 grain weight of 26-29 g. Lines included are IPB107-F-5-1-1, IPB107-F-65-3-1, IPB116-F-44-1-1, dan IPB116-F-46-1-1. In general, some of the lines tested showed superiority on some characters, such as short growth duration, large panicle, and number of grain a lot. Research shows the percentage of grain is still high vacuum.

Judul: Perbandingan Karakteristik Anatomi Skelet Kepala Komodo (Varanus komodoensis) dan Biawak Air (Varanus salvator).
Abstrak: Komodo dan biawak air diklasifikasikan dalam Ordo Squamata dan Famili Varanidae. Meskipun kedua hewan ini termasuk dalam ordo dan famili yang sama tetapi perannya di alam berbeda. Komodo sebagai predator utama memiliki ukuran tengkorak yang lebih besar dibandingkan dengan ukuran tengkorak biawak air yang berperan sebagai predator opportunistik. Penelitian ini bertujuan untuk mempelajari komparasi karakteristik struktur skelet kepala komodo (Varanus komodoensis) dengan skelet kepala biawak air (Varanus salvator). Struktur kepala ini dikaitkan dengan fungsi skelet kepala untuk mendukung perilaku sehari-hari. Penelitian ini dilakukan dengan cara mengamati dan mengukur tulang-tulang penyusun skelet kepala komodo dan biawak air, serta mengamati perilaku sehari-hari kedua hewan melalui pengamatan video. Hasil penelitian menunjukkan ukuran skelet kepala komodo memiliki panjang 21.9 cm, lebar 11.6 cm, dan tinggi 8.9 cm. Skelet kepala biawak air memiliki panjang 16.0 cm, lebar 7.0 cm, dan tinggi 5.0 cm. Komodo memiliki gigi marginal dan lingual dengan tipe gigi pleurodont dan ziphodont, yaitu bentuk gigi seperti pedang dan melengkung ke arah lateral. Biawak air memiliki gigi marginal dengan tipe pleurodont yang tumbuh disamping rahang dengan satu gigi pengganti pada setiap gigi marginal. Hubungan antar tulang penyusun skelet kepala komodo relatif longgar dan memiliki os temporale yang sangat berkembang, sehingga pembukaan mulut komodo sangat lebar dibandingkan biawak air yang tidak memiliki kraniokinesis. Kedua hewan ini memiliki canalis intercisivum yang terdapat pada palatum durum menghubungkan cavum oris dan cavum nasi. Secara fungsional, saluran ini dikaitkan dengan kemampuan penciuman yang tajam karena saluran ini berhubungan dengan organ vomeronasale. Perbedaan struktur skelet kepala komodo dan biawak air berperan dalam melakukan aktifitas sehari-hari kedua hewan ini.
