Judul: The Effectiveness of Vermicompost Fertilizer and  Arbuscular Mycorrhizal Fungi in Increasing the Productivity of Alfalfa Plants (Medicago sativa L.)
Abstrak: Penelitian ini bertujuan menguji pengaruh pemberian pupuk vermikompos dan fungi mikoriza arbuskula (FMA) terhadap produktivitas tanaman Alfalfa (Medicago sativa L.). Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 220 sampel yang dibagi menjadi 11 perlakuan dan 20 ulangan. Perlakuan terdiri dari K0 = Media tanah tanpa perlakuan; K100 = K0 + 100% NPK; K50 = K0+ 50% NPK; AV1 = K50 + 100 g vermikompos; AV2 = K50 + 200 g vermikompos; AF1 = K50 + 10 g FMA; AF2 = K50 + 20 g FMA; AVIF1 = K50 + 100 g vermikompos + 10 g FMA; AV1F2 = K50 + 100 g vermikompos + 20 g FMA; AV2F1 = K50 + 200 g vermikompos + 10 g FMA; AV2F2 = K50 + 200 g vermikompos + 20 g FMA. Parameter yang diukur adalah persentase kolonisasi akar, tinggi tanaman, jumlah cabang, jumlah daun, diameter batang, panjang akar, berat segar akar, berat segar tajuk, dan berat kering tajuk. Hasil penelitian menunjukkan bahwa perlakuan kombinasi vermikompos dan FMA sangat berpengaruh nyata (P<0,01) dalam meningkatkan seluruh parameter yang diamati. Simpulan dari penelitian ini adalah kombinasi pupuk vermikompos 200 g dan FMA 10 g efektif meningkatkan produktivitas tanaman Alfalfa., TThis study aims to examine the effect of vermicomposting and arbuscular mycorrhizal fungi (AMF) on the productivity of Alfalfa plants (Medicago sativa L.). This study use a randomized complete design with 220 samples divided into 11 treatments and 20 repeats. The treatment consists of K0 = untreated media; K100 = K0 + 100% NPK; K50 = K0 + 50% NPK; AV1 = K50 + 100 g vermicompost; AV2 = K50 + 200 g vermicompost; AF1 = K50 + 10 g AMF; AF2 = K50 + 20 g AMF; AVIF1 = K50 + 100 g vermicompost + 10 g AMF; AV1F2 = K50 + 100 g vermicompost + 20 g AMF; AV2F1 = K50 + 200 g vermicompost + 10 g AMF; AV2F2 = K50 + 200 g vermicompost + 20 g AMF. The parameters measured are percentage of root infection, plant height, number of branches, number of leaves, stem diameter, root length, fresh weight of roots, fresh weight of leaves and steam, and dry weight of leave and steam The results showed that the combination treatment of vermicompost and FMA had a significant effect (P<0.01) in improving all observed parameters. The conclusion of this study is that the combination of vermicompost fertilizer 200 g and FMA 10 g effectively increases the productivity of Alfalfa plants.

Judul: Pengaruh Pemupukan dan Pemberian Urin Sapi Terhadap Pertumbuhan dan Tingkat ProduktivitasMedicago sativa L
Abstrak: Medicago sativa L (Alfalfa) is one of kind legume comes from Iran (Cheeke 2005). This research was conducted to measureeffect of fertilized with manure and urin of cattleforgrowth and production of alfalfa with same value of nitrogen where was tried in Ciwidey, Bandung. This research used Randomized Complete Design (RCD) with 5 treatments and 3 replications. The treatment were P1 (NPK (control) 15 g m-2), P2 (manure of chicken 0.33 kgm-2), P3 (manure of cattle 1 kgm-2), P4 (manure of chicken 0.17 kgm-2+ urine 0.3 litersm-2), and P5 ( manure of cattle 0.5 kgm-2+ urine 0.3 litersm-2). The observation was the response of plant which include presentage of seed, plant height, total leaf, as feed and dry matter of leaf and stem, crude protein and crude fiber. The result showed that the treatment of iso nitrogen which fertilized with manure and urin of cattle is not significant togrowth and productivity of alfalfa. Another result of this reaserch is the treatment P4 (manure of chicken 0.17 kgm-2+ urine 0.3 litersm-2) can subtitution NPK and showed the better growth, productivity and crude protein of alfalfa than NPK treatment.

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.
