Judul: Formulasi ekstrak daun jambu (Psidium guajava) dan daun sirsak (Annona muricata) untuk menghambat proliferasi sel kanker
Abstrak: Daun jambu biji merah (Psidium guajava) mengandung senyawa kuersetin dan sirsak (Annona muricata) mengandung senyawa kaempferol yang masingmasing telah diketahui memiliki aktivitas antikanker. Tujuan penelitian ini adalah mengevaluasi efek sinergis campuran fraksi kaya-kaempferol dari daun sirsak dan fraksi kaya-kuersetin dari daun jambu biji merah dalam menghambat proliferasi sel kanker secara in vitro. Ekstrak metanol didapatkan melalui maserasi dengan sonikasi setelah sebelumnya sampel daun yang telah diserbukkan disoxhletasi menggunakan pelarut n-heksana. Ekstrak dari kedua daun masing-masing dipisahkan menggunakan kromatografi cair vakum sehingga didapatkan sebanyak 2.6% fraksi kaya-kaempferol dan 2.2% fraksi kaya-kuersetin. Kedua fraksi diformulasikan dalam berbagai formula (8:2, 6:4, 5:5, 4:6, 2:8) dan dilihat efek penghambatannya terhadap sel Vero (sel normal) dan Raji (sel kanker darah). Persen penghambatan sel Raji oleh formula kedua fraksi memiliki nilai di bawah 30%. Formula fraksi kaya-kaempferol dari daun sirsak dan fraksi kaya-kuersetin dari daun jambu tidak memiliki efek sinergis maupun antagonis dalam menghambat proliferasi sel Raji secara in vitro.

Judul: Kemampuan Ekstrak Dedaunan Berpotensi Antioksidan Untuk Memodulasi Apoptosis Pada Sel Khamir.
Abstrak: One of the causes of cardiovascular disease is atherosclerosis. Some of medicinal herbs extracts which are reported to have anti atherosclerotic property are Guava leaves extract, Jati Belanda leaves extract, and Salam leaves extract. Apoptosis occures in atherosclerosis lesions intima. So this research is to determine that the capability of some herbal extracts to modulate apoptosis in yeast cells. For that purpose, yeast cells are used as model, as they will become small colonies (petite colonies) when apoptosis is induced. Yeast cells were incubated into 50 ppm, 100 ppm, 200 ppm, 1000 ppm, and 2000 ppm of each extracts, previously had been enriched in sterile YEPD and Petite Broth. On day 3 and 4, yeast cells were spread into YEPD and Petite media, and then petite frequency was counted directly from the plate. Promising extract for apoptosis stimulation on yeast cells is the 100 ppm Salam leaves extracts has petite frequency of 97.90%, whereas the 1000 ppm and 2000 ppm petite frequency are respectively 94.45% and 91.99%. No petite colony was formed on other extracts. Guava leaves extracts at 100 ppm inhibits apoptosis on yeast cells.

Judul: Hubungan Perilaku Menonton Orang Pinggiran di Trans 7 dengan Empati Remaja di Desa Cihideung Ilir Kecamatan Ciampea Bogor
Abstrak: This study aimed to analyze the correlation between internal factors adolescense with viewing behavior, the correlation between external factors adolescense with viewing behavior, and correlation viewing behavior with adolescense empathy. The research sample was adolescense in Cihideung Ilir Village Ciampea District Bogor who had seen the program in “Orang Pinggiran” Trans 7. The results of the study explain that the gender associated with the duration of the watch. Age, level of education, occupation, and television ownership was not associated with viewing behavior. On testing the interaction with family and interaction with friends wasreal associated with viewing behavior. Finally, the viewing behavior of “Orang Pinggiran” Trans 7 was not associated with adolescense empathy.
