Judul: Siklus Reproduksi Anak Tikus Dari Induk Yang Diberi Ekstrak Etanol Akar Purwoceng Selama 13–21 Hari Kebuntingan.
Abstrak: Purwoceng (Pimpinella alpina) is one of Indonesian medicinal herbals that was originating from high altitudes area such as Dieng at Central Java. Its root has an efficacious as aphrodisiac because of its compound such as isoflavon group. The aim of this study was to test the efficacy of phytoestrogens contained in purwoceng (Pimpinella alpina) on the descended testes, vaginal opening and estrous cycle. This study used two groups of pregnant rats. The first group consist of four pregnant rats which were given purwoceng root ethanol extract with dose of 25 mg / ml per 300 g BW orally at 13–21 gestation. The second group of rats were given water at the 13th day of gestation to 21 as a control. All pregnant rats were selected rats which has delivered 8–9 pups. The results showed that time of descended testes and vaginal opening of purwoceng group was earlier than control, descended testes of purwoceng group was on day 29 and vaginal opening was on day 36. Descended testes of control group was on day 34 and vaginal opening was on day 38. Length of estrous cycle in purwoceng group were longer than control with proestrus and estrus phase were also longer than control.

Judul: Perkembangan Tulang Anak Tikus Betina Yang Induknya Diberi Ekstrak Etanol Akar Purwoceng Selama 13–21 Hari Kebuntingan
Abstrak: Tulang merupakan bagian dari sistem gerak yang menentukan performa dari hewan. Perkembangan tulang dimulai pada hari ke-10 kebuntingan pada saat organogenesis. Perkembangan tulang melalui proses proliferasi dan diferensiasi osteoblas yang diatur oleh growth factor seperti insulin like growth factor (IGF I dan II), bone morphogenic proteins (BMPs), fibroblast growth factor (FGF), dan flatelet-derived growth factor (PDGF) dan estrogen. Penelitian ini bertujuan menguji khasiat fitoestrogen pada akar purwoceng (Pimpinella alpina) terhadap pertumbuhan tulang anak tikus betina. Penelitian ini menggunakan dua puluh ekor tikus bunting yang terdiri dari dua kelompok. Kelompok pertama terdiri atas sepuluh ekor tikus bunting yang diberi ekstrak etanol akar purwoceng dengan dosis 25 mg/ml per 300 g bobot badan pada kebuntingan hari ke-13–21. Kelompok kedua terdiri atas sepuluh tikus bunting yang diberi air pada 13–21 hari kebuntingan sebagai kontrol. Anak tikus betina yang menjadi sampel diambil dari induk yang melahirkan anak dengan jumlah 8–9 ekor. Perkembangan tulang dari anak tikus diukur dari hari pertama kelahiran sampai dengan berusia tujuh minggu (49 hari). Hasil penelitian ini menyatakan bahwa, perkembangan tulang anak tikus betina yang diberi ekstrak etanol akar purwoceng lebih panjang dibandingkan kelompok anak tikus kontrol.

Judul: Pengaruh Perubahan Luasan Glaciers Puncak Jaya Papua Indonesia Terhadap Kapasitas Panas dengan Menggunakan Citra Satelit TM/ETM+
Abstrak: Puncak Jaya glaciersis one of tropical glaciers in the earth that exists in Papua Island, Indonesia- Papua New Guinea. Glaciers have important function as phenomenon record, freshwater storage, and climate change indicator. Area, net radiation, and surface temperature of glaciers were measured by remote sensing method using landsat imagery data in 1989, 1997, 1999, 2000, 2004, 2007, and 2009. Glaciers area was measured by researcher using manual delination and using ArcGIS 9.3 to measure area. Glaciers volume was estimated using Bahr empirical formula, V = β A γ. The result showed total area loss in Puncak Jaya is 72,1% from 4,409 km2 in 1989 to 1,231 km2 in 2009. Total glaciers volume loss from 1989 to 2009 is 77,47%from 123,3 (10-3 km3) to 28,2 (10-3 km3). Nett radiation in glaciers area ranges from 107,5 W/m2 to 294,5 W/m2 with nett radiation mean per year per ice mass 206,2 W/m2. Glaciers albedo ranges from 0,19 to 0,53 with albedo mean per year per ice mass 0,37. Glaciers surface temperature ranges from -7,0oC to 7,0oC with surface temperature meanper year per ice mass -0,6oC. Heat capacity in glaciers area ranges from 0,30 (x 106 MJ K-1) to 110,37 (x 106 MJ K-1) from 1989 to 2009.
