Abstrak: The research was conducted at Cibungur, Karawang Wetan, Karawang. Soil analysis carried out at the soil Laboratory, Department of Soil Science and Land Resources, agriculture faculty of IPB. The research was conducted from December 2012 to March 2013. The research design used was Randomized Plots Divided (Split Plot Randomized Block design). This research using a factorial design with two factors, namely bio-fertilizers and organic fertilizers. Data analysis using analysis of variance (F test), if real then by DMRT (Duncan Multiple Range Test) at the level of 5%. Treatment consisted of two biological fertilizer levels that is 2 l ha-1 application-1 and 0 l aplikasi-1 ha-1. Treatment of solid organic fertilizer consist of six levels, namely: 0 ton ha-1, 2 ton ha-1, 4 ton ha-1, 6 ton ha-1, 8 ton ha-1, and 10 ton ha-1 . The purpose of this study was to determine the effect of a combination of organic fertilizer with bio-fertilizers on organic rice farming. Applications POP 10 ton ha-1 resulted height plant, biomass plant, 1000 grain weight, GKP and GKG highest to all treatments. Application POP 8 and 10 ton ha-1 combined with bio-fertilizers can increase the yield of 6 and 10% grain yield, while treatment 2-6 ton ha-1 dont improve outcomes compared with control. POP dose 8-10 ton ha-1 increase grain yield around 10%.

Abstrak: The experiment was conducted at Cikarawang, Dramaga, Bogor from November 2012 to March 2013. This study aims to determine the most appropriate time in manure application and the effect of bio-fertilizer. This experiment used the split plot experimental design with two factors and 4 replications. The first factor was time of chicken manure application with 4 treatments i.e. application of 10 ton chicken manure / ha applied 2 weeks before planting, 10 ton/ha applied 4 weeks after planting, 10 ton/ha applied 6 weeks after planting, 5 ton/ha applied 2 weeks before planting and 5 ton/ha 4 weeks after planting. The second factor was the application of bio-fertilizer (with and without bio-fertilizer). There were 32 experimental units. The highest rice yield (5.04 ton dry grains/ha) was found from the application of 5 ton chicken manure / ha 2 weeks before planting and 5 ton/ha 4 weeks after planting with additional of bio-fertilizer.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
