Judul: Pengaruh cara pemberian air pada metode Sri terhadap sifat fisik tanah, pertumbuhan, dan produksi tanaman padi
Abstrak: SRI (System of Rice Intensification) is a set of some principle and techniques to obtain higher paddy production from genotipe or variety, modern or traditional, hybrid, etc. This technique use the approach of increasing root growth and biota population. Several report of SRI in many regions show that SRI can reach 7-10 ton/ha of production, but this result has not been generally similar in all region.

Judul: Pengaruh Perbedaan Karakteristik Kimia dan  Mineral serta Penambahan Bahan Organik terhadap Pertumbuhan dan Produksi  Padi yang Ditanam dengan Metode SRI
Abstrak: The necessity of food especially rice increase with increasing in human population. One of a very popular system in the cultivating of paddy is the System of Rice Intensification (SRI). Although SRI is believed can increase the paddy production without inorganic fertilizer and optimizing water use, but there are several problems which has not been fully understand yet in order to apply SRI, especially about the land condition. This research was aimed to study mineralogical and chemical soil characteristics and organic matter application in order to support the growth and the production of paddy cultivating by comparing SRI and conventional method. Soil samples were collected from four locations i.e: Cihideung, Bogor (Chd, Bgr), Sindangbarang, Bogor (Sbr, Bgr), Margakaya, Karawang (Mgk, Krw) and Bobojong, Cianjur (Bbj, Cjr), two water management levels, i.e: convensional (K) and SRI with irrigation during five days (S). Each water management levels were combined with two treatments of organic matter applications, i.e: plus compost application (B1) and without compost application (BO). Treatments were desained in Factorial Completely Random Design with 16 treatments and three times replications. Totally there were 48 experimental units. Chemical properties (C-organic, total N, and K) of Bobojong soil showed better result than the other soils, and the texture of Cianjur soil was silty clay. Quartz was the most dominant mineral in sand fraction for all soils, and kaolinite was the most abundant mineral in clay fraction. It was also found easily weathered mineral which show that natural fertility in the research location were high, especially on Sindangbarang and Cianjur soils. Compost application 7 ton/ha was not significantly different in increasing the production and the growth of paddy. Water irrigation using SRI method during five days also can not increase the production and the growth of paddy, except if both treatments were combined. Meanwhile, based on the production and the growth parameters, Sindangbarang (Bogor) soil showed better response for SRI application than other soil. SRI application in different soils gave variety results for paddy production.

Judul: Ekspresi Gen Bax dan Bcl-2 pada Macaca fascicularis sebagai Hewan Model Penelitian Papillomavirus
Abstrak: Kanker serviks adalah salah satu kanker yang menempati posisi keempat di dunia yang terjadi pada wanita. Infeksi Papillomavirus telah dilaporkan sebagai satu dari sekian banyak faktor penyebab kanker serviks. Mekanisme terjadinya kanker serviks tidak lepas dari adanya penekanan atau hambatan proses apoptosis. Monyet ekor panjang telah banyak digunakan sebagai hewan model penelitian karena memiliki kesamaan dengan manusia dari segi genetik, anatomi, dan fisiologi dibandingkan dengan hewan lainnya. Monyet ekor panjang dilaporkan telah terinfeksi secara spontan oleh Papillomavirus, namun tidak menunjukkan gejala yang mengarah pada kanker serviks. Penelitian ini bertujuan untuk mengevaluasi ekspresi 2 gen yang berperan dalam proses apoptosis yaitu Bax dan Bcl-2 pada monyet ekor panjang yang positif versus negatif Papillomavirus. Uji ekspresi gen dilakukan dengan teknik Real time PCR (RT-qPCR). Hasil penelitian menunjukkan bahwa ekspresi gen Bax dan Bcl-2 lebih tinggi pada monyet ekor panjang positif terinfeksi Papillomavirus. Ekspresi gen Bcl-2 (anti apoptosis) meningkat lebih tinggi dari gen Bax (pro apoptosis). Ekspresi gen Bax dan Bcl-2 berpotensi menjadi penanda genetik kejadian kanker pada monyet ekor panjang yang terinfeksi Papillomavirus.
