Judul: Komunitas Fauna Tanah Pada Empat Tipe Ekosistem yang Berbeda.
Abstrak: Deforestation or changes in the function from forest to non-forest ecosystems has been playing a role in the change of ecosystem and species in it. Soil fauna is one of is an interesting aspect to be studied. This experiment was conducted in Bungku, District Bajubang, Batanghari Regency, Jambi. Sampling technique using hand sorting method in fourth ecosystem. The fourth ecosystem mentioned is secondary forest (BF), jungle rubber (BJ), oil palm plantations (BO), and rubber plantations (BR). The results found there were 271 individuals are included in 43 familys, 19 orders from 7 class i.e. Insecta, Chilopoda, Collembola, Clitellata, Malacostraca, Arachnida, and Diplopoda, with 2 phylum i.e. Arthropoda and Annelida. Secondary forest is an ecosystem that relatively stable with the value of diversity index H '= 2.50, index of richness DMg = 5.05, and index of evenness E = 0.81. General distribution pattern on the four ecosystems is uniform, with Id value <1. The high diversity of soil macro-fauna was related with soil fertility.

Judul: Perbandingan Keanekaragaman Semut (Hymenoptera: Formicidae) Pada Empat Tipe Ekosistem yang Berbeda
Abstrak: Deforestation or transformation of forest function to non-forest has been playing a role in the changes of ecosystem and species in it. Insect as one of the living fauna that live in the forest is an interesting aspect to be studied, especially ants. This experiment was conducted in Bungku, Bajubang District , Batanghari Regency, Jambi. Sampling technique using pitfall traps in four ecosystem. The four ecosystem mentioned is secondary forest, oil palm plantations, rubber plantations, and jungle rubber. The results found there were 5 484 individuals of 50 ant morphospecies, 33 genera of 6 subfamily i.e. Formicinae, Myrmicinae, Ponerinae, Dolichodorinae, Pseudomyrmicinae, and Dolichorinae. Secondary forest is an ecosystem that relatively stable with the value of diversity index H '= 2.76, index of richness DMg = 4.96, and index of evenness E = 0.70. The ant communities depend on environment factor of each ecosystem.

Judul: Optimasi Pemurnian Protein Kapang Endofit CgKTm 5F  sebagai Inhibitor RNA Helikase Virus Hepatitis C
Abstrak: Hepatitis C adalah salah satu penyakit yang menyebabkan peradangan hati. Obat atau vaksin yang efektif untuk pengobatan hepatitis C belum diketahui. Penemuan terapi target molekular NS3 helikase memiliki potensi sebagai salah satu cara untuk penghambatan penyakit hepatitis C. Penghambat NS3 helikase yang memiliki nilai kemurnian yang tinggi masih belum didapatkan sehingga diperlukan penelitian untuk mengoptimasi teknik pemurnian kapang endofit CgKTm 5F sebagai penghambat RNA helikase virus hepatitits C. Pemurnian kapang endofit CgKTm 5F dilakukan dengan menggunakan beberapa macam teknik kromatografi, yaitu gel filtrasi, penukaran ion, hidrofobik dan kromatografi lapis tipis. Kromatografi gel filtrasi dengan sephadex G-50 dan eluen etanol 30% memiliki aktivitas inhibisi tertinggi (89,45%) pada fraksi ke-10. Analisis SDSPAGE menunjukkan bahwa kapang endofit CgKTm 5F adalah pita tunggal sebesar 13,97 kDa dan aktivitas spesifik sebesar 3.62x10-5 U/mg serta persen kemurnian sebesar 99,93%. Kemurnian ini 20x lebih tinggi dibandingkan dengan penelitian sebelumnya sebesar 5,83 %.
