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: Produktivitas dan Kualitas Nutrisi Sorghum bicolor (L.) Moench dan Centrosema pubescens Benth pada Pemberian Vermikompos Eisenia foetida Savigny
Abstrak: Vermicompost is one of organic materials that can increase nutrient contents in the soil. The aim of this study was to evaluate the productivity and nutrient quality of Sorghum bicolor (L.) Moench numbu variety and Centrosema pubescens Benth on some level vermicompost of Eisenia foetida Savigny earthworm. The parameters measured in this study were total of leaves, vertical height, fresh weight, dry weight, crude protein, phosphorus and potassium. This study used a completely randomized design with 3 replications to plants. The level of vermicompost is V0 (0%), V25 (25%), V50 (50%), V75 (75%) and V100 (100%). The type of plants used is Sorghum bicolor (L.) Moench and Centrosema pubescens Benth. Results showed that vermicompost was significant on plant productivity of both plants, whereas nutrition quality is just significant in Shorgum bicolor (L.) Moench.

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.
