Judul: Evaluasi Produktivitas Tanaman Sorghum (Sorghum bicolor) Varietas Numbu Terhadap Pemberian Vermikompos dan Cacing Tanah Eisenia foetida
Abstrak: Vermicompost is organic fertilizer which is created by worm contribution. Vermicompost can increase hara content that needed by plant to grow. This study was conducted to evaluate productivity of Sorghum bicolor (L.) Moench by adding vermicompost and worm Eisenia foetida in different level. The measured parameters in this study were plant height, amount of leaves, as fed weight, dry matter weight and nutrient quality that composed by N (Nitrogen), P (Phospor), and K (Potasium). The study was arranged by factorial completely randomized design 3x3 with 3 replications. The first factor was vermicompost addition level 0%, 12.5% and 25%, the second factor was Eisenia foetida worm addition level 0, 16 and 32 heads. The result showed that by 25% vermicompost adding, it increased productivity and nutrient quality of Sorghum bicolor plant (P<0.05). On the other hand, the addition of Eisenia foetida worm affected the vertical height of plants but it did not influence nutrient quality of Sorghum bicolor plant

Judul: Pengaruh Populasi Cacing Tanah Eisenia foetida, Pupuk NPK dan Kapur terhadap Produktivitas dan Kualitas Sorgum (Sorghum bicolor L. Moench) Varietas Numbu pada Latosol Dramaga
Abstrak: Eisenia foetida is known as potential earthworm to reorganize the organic matter into inorganic matter that are beneficial to plants. This research aimed to determine the influence of population of earthworm E. foetida, NPK fertilizer and lime to productivity and nutritional quality of sorghum (Sorghum bicolor L. Moench) in Latosol Dramaga. The observed variables were the vertical height of plants, number of leaves, fresh weight, dry matter, crude protein, crude fiber and content of calcium. This research used factorial completely randomized design 2x2x3 with 3 replications. The results showed that the combination NPK fertilizer and earthworm significantly (P<0.05) increased the productivity of the plant. The Quality of nutrition, crude protein and calcium (Ca), significantly increased (P<0.05) and respectively influenced by NPK fertilizer and lime. Whereas the crude fiber, very markedly decreased (P<0.01) in influenced by the interaction between NPK fertilizers and earthworm.

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.
