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: Evaluation of Social Forestry Programs in Protected Forest Areas: A Case Study of HKm Kalibiru in the Kulon Progo District
Abstrak: Perhutanan Sosial adalah sistem pengelolaan hutan lestari yang dilaksanakan oleh masyarakat setempat untuk meningkatkan kesejahteraan masyarakat, keseimbangan lingkungan, dan dinamika sosial budaya. Program ini juga dikaitkan dengan upaya pencapaian Tujuan Pembangunan Berkelanjutan (Sustainable Development Goals/SDGs) sebagai bentuk kontribusi Indonesia sebagai warga global. Penelitian ini bertujuan untuk mengevaluasi program Perhutanan Sosial terhadap tercapainya tiga tujuan utama yaitu secara sosial, ekologi dan ekonomi. Pengambilan data dilakukan melalui wawancara mendalam secara online dan studi dokumen. Penelitian dilakukan pada Perhutanan Sosial pola Hutan Kemasyarakatan (HKm) di kawasan Hutan Lindung Kulon Progo. Hasil penelitian menunjukkan 1) dengan adanya program Perhutanan Sosial, masyarakat bisa guyub dan merencanakan tata kelola hutannya karena adanya organisasi dan aturan main yang inovatif; 2) dampak Perhutanan Sosial secara ekologi mendorong masyarakat untuk menjadikan kawasan HKm Kalibiru tetap tumbuh dan lestari dengan melakukan konservasi, perlindungan dan pengamanan hutan; 3) dampak program Perhutanan Sosial secara ekonomi meningkatkan pendapatan ekonomi masyarakat dan menyerap banyak tenaga kerja. Setelah mengikuti Perhutanan Sosial, pendapatan masyarakat di HKm Kalibiru meningkat sekitar 85%. Bila pada era sebelum Perhutanan Sosial, pendapatan petani sebesar Rp. 800.000 per bulan; maka pada era dengan Perhutanan Sosial pendapatan meningkat menjadi Rp 2.000.000 per bulan., Social Forestry is sustainable forest management system implemented by local communities to increase community welfare, environmental balance and social cultural dynamics. This program is also associated with efforts to achieve the Sustainable Development Goals (SDGs) as a form of Indonesia’s contribution as a global citizen. This study aimed to evaluate the Social Forestry program on the achievement of three main objectives: socially, ecologically, and economically. By online interviews and document studies, this study was conducted at the Social Forestry area in the Community Forest scheme located at Protected Forest of Kulon Progo. The results showed that the impacts of the Social Forestry program were 1) the community can work together and plan their forest management by the innovative organization and rules; 2) it encourages the community to keep the HKm Kalibiru area growing and sustainable by conserving, protecting and securing the forest; 3) it increase people’s economic income and absorb a lot of workers. After participating in Social Forestry, people’s income in HKm Kalibiru increased around 85%. Before the Social Forestry, people’s income was Rp 800.000 per month; after the Social Forestry income increased to Rp 2.000.000 per month.

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.
