Judul: Persepsi, Motivasi dan Perilaku Masyarakat Adat terhadap Pengelolaan Kawasan Hutan (Kasus Kawasan Hutan Sekitar Desa Sindanglaya Banten)
Abstrak: Keberadaan hutan bagi masyarakat adat sekitar hutan mempunyai nilai manfaat ekonomi, ekologi dan sosial. Pemberdayaan masyarakat menjadi salah satu hal penting dalam menjaga kelestarian hutan. Penelitian ini mengkaji persepsi, motivasi dan perilaku masyarakat adat dalam memanfaatkan dan mengelola hutan. Metode yang digunakan adalah wawancara mendalam dengan pemilihan informan menggunakan teknik snowbal, observasi dan studi pustaka. Tingkat persepsi masyarakat terhadap keberadaan hutan di Desa Sindanglaya tergolong baik, sedangkan persepsi masyarakat terhadap nilai fungsi ekonomi hutan sebagai sumber kayu dan tambahan pendapatan bagi rumah tangga masih rendah. Motivasi masyarakat Kasepuhan Pasir Eurih dalam menjaga kelestarian hutan sudah baik, namun sebagian besar masyarakat yang bermukim di Kasepuhan Pasir Eurih masih mempunyai tingkat motivasi ekonomi yang rendah. Perilaku masyarakat dalam memanfaatkan Hutan Bongkok sudah baik. Perbandingan pengelolaan hutan menurut ilmu pengetahuan kehutanan dan masyarakat Kasepuhan Pasir Eurih pada dasarnya sama, namun cara pelaksanaan pengelolaan di lapangan berbeda.

Judul: Persepsi, Motivasi dan Perilaku Masyarakat Sekitar Hutan dalam Pengelolaan Kawasan Hutan (Kasus Kawasan Hutan sekitar Desa Gunung Sari di Kecamatan Pamijahan, Kabupaten Bogor)
Abstrak: The existence of forests to local communities surrounding the forest area gives economic, ecological, and social benefits. Empowering communities is the one of the important thing to preserve forests. The study assess the perceptions, motivations and behavior in using and managing forests. The method has been used was a structured interview (questionnaire) by taking a purposive sampling respondents, observation and literary study. The level of public perception for the existence of forest in the village of Gunung Sari is relatively good, whereas the public perception of the value of the economic functions of forests as sources of timber and additional income for poor households. Furthermore, the biggest motivation (35.48%) to manage forests based on the theory of Maslow (1943) was due to the need of security (safety needs), while the biggest behavior motivation based on the theory of Gerungan (1967) was group motif with a percentage of 32.26%. Behavior of people who used and managed the forest have been shown by utilizing water resources well, planted of forest trees, and didn’t convert land of the forest.

Judul: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
