Judul: Perception of Kutamanah Village Community on Social Forestry Program in KPH Purwakarta
Abstrak: Perhutanan Sosial adalah program Kementerian Lingkungan Hidup dan Kehutanan bertujuan memberikan persetujuan untuk membangun sistem pengelolaan sumberdaya hutan lestari pada kawasan hutan negara atau hutan hak dengan melibatkan masyarakat setempat sebagai pelaku atau mitra. Implementasi program perhutanan sosial menghadapi berbagai kendala yang mengakibatkan terhambatnya pemberian izin program perhutanan sosial kepada masyarakat sekitar hutan. Tujuan dari penelitian ini adalah mengetahui persepsi masyarakat terhadap perhutanan sosial di Desa Kutamanah. Penelitian ini menggunakan metode survey dengan memilih responden secara sengaja yang terdiri dari 60 responden. Hasil penelitian menunjukan bahwa responden memiliki persepsi yang sedang terhadap kondisi hutan yang ada disekitar Desa Kutamanah dan manfaat program perhutanan sosial karena pelaksanaan perhutanan sosial dinilai berjalan kurang baik. Hal tersebut terjadi dikarenakan masyarakat tidak mendapatkan sosialisasi yang memadai tentang perhutanan sosial dan belum pernah mendapat pelatihan untuk pengelolaan hutan lestari. Indikator pendapatan berhubungan kuat dan nyata hanya dengan persepsi tentang hutan. Hal tersebut menunjukan bahwa pendapatan masyarakat sangat bergantung dari sumber daya hutan., Social Forestry is a program of the Ministry of Environment and Forestry which aims to provide permits to develop a sustainable forest resource management system in the forest areas or the private forests by involving local communities as actors or partners. The implementation of social forestry programs faces various obstacles that delay granting permits for social forestry programs to communities around forests. The purpose of this study was to determine the community's perception of social forestry in Kutamanah Village. This study used a survey method by selecting respondents intentionally consisting of 60 respondents. The results showed that respondents had a moderate perception of the condition of the forest around Kutamanah Village and the benefits of the social forestry program because the implementation of social forestry was considered to be running poorly. It's happened because the community did not receive adequate socialization about social forestry and never received training for sustainable forest management. Income indicators are strongly and significantly related to perceptions of respondent on forests. It's probably because people's income is very dependent on forest resources.

Judul: The Contribution of Social Forestry to the Income of Communities Around Forest Farmers in KPH Purwakarta
Abstrak: Berbagai permasalahan kehutanan yang terus terjadi di Indonesia menuntut perlunya solusi konkrit dalam mencegah degradasi dan deforestasi. Perhutanan Sosial hadir sebagi sebuah solusi untuk dapat menciptakan hutan yang lestari dan masyarakat yang sejahtera. Penelitian ini bertujuan menganalisis perkembangan program Perhutanan Sosial dan seberapa besar kontribusi yang diberikan terhadap pendapatan petani di wilayah KPH Purwakarta. Data dikumpulkan menggunakan metode wawancara kepada 40 orang petani yang tergabung dalam Lembaga Masyarakat Desa Hutan Bambu Jaya yang mendapatkan izin Perhutanan Sosial melalui Pengakuan dan Perlindungan Kemitraan Kehutanan (Kulin KK). Hasil penelitian menunjukkan bahwa kontribusi Perhutanan Sosial terhadap pendapatan rumah tangga petani LMDH Bambu Jaya yaitu sebesar 11,85%, hasil analisis faktor menunjukkan bahwa faktor yang memengaruhi pendapatan petani LMDH Bambu Jaya adalah luas lahan, dan tingkat kesejahteraan petani Perhutanan Sosial LMDH Bambu Jaya berada pada tingkat kesejahteraan sedang dan cukup hidup layak., Various forestry problems that continue to occur in Indonesia require the need for concrete solutions to prevent degradation and deforestation. Social Forestry is present as a solution to be able to create sustainable forests and prosperous communities. This study aims to analyze the development of the Social Forestry program and how much it contributes to the income of farmers in the KPH Purwakarta area.

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.
