Dapat dikatakan bahwa hutan rakyat di Kecamatan Sa’dan, Desa Sa’dan Andulan, Kabupaten Toraja Utara hanya sebagai usaha sampingan. Kata kunci : kontribusi, hutan rakyat ABSTRACT DICKY PRIBADI MANDA. Tongkonan-Based Community Forest Contribution to Farmers' Household Income in Sa'dan District, North Toraja Regency (Case Study: Sa'dan Andulan Village). Supervised by HANDIAN PURWAWANGSA. Community forests are forests that are built, managed, and utilized by the people on owned land. Its development is aimed only at vacant land and often only as a support for agriculture. The purpose of this study was to determine the pattern of community forests and the contribution of community forests to farmers' household incomes in Sa'dan District, Sa'dan Andulan Village, North Toraja Regency. Data were collected through interviews and literature studies. The analysis shows that community forests in Sa'dan District, Sa'dan Andulan Village, North Toraja Regency use agroforestry business patterns. The contribution of timber community forests is 6.49%, while the contribution of non-timber forest products (HHBK) is 9.08%.

Abstrak: The pressure on forest resources led to an excessive exploitation of forest resource so that it no longer able to provide optimal benefits even otherwise cause damage and decreased productivity of forest resources. One alternative solution to this problem is to plant forests construction in forest areas that are not productive especially outside Java or other alternatives is the construction of the community forest in the island of Java also outside of Java island. The result of the community forest development activities in addition to the ecologically can support the environment, can also be produced folk wood currently has evolved into a commodity which has a pretty good economic value and perceived by the public that this effort can provide extra income. The community forest as an approach to development of forestry is also prolific on environmental sustainability and an increase in people's income, so that needs to be developed with the better, so as to provide a high timber production and improve the welfare of farmers, while paying attention to power support and function of forests. This research aims to understand further the characteristics and role of the community forest in the Pasir Madang region, particularly from aspect of the community forest’s role against the welfare of the family. This research studies economic condition community forest farmers through the calculation of the balance of the income and spending the community forest farmer families. Further this research examines the contribution of community forest against the peasant household family income and identifying the motivation of farmers in community forest management. Data collected through interview of selected respondens of community forest farmers by using purposive sampling method. Additional information collected through literature studies on secondary data sources from a variety of related government agencies. Respondents farmers who is interviewed in this study consisted of 30 people who come from the village of Pasir madang, Bogor regency, West Java. Based on these studies it is known that most of the people in the village of Pasir Madang managed using agroforestry systems. The community forest in the Pasir Madang village serves as the public savings which can be harvested when the farmer needed the money in relatively large amounts and in urgent circumstances. A pattern of harvesting as it is known in terms of as a “tebang butuh” system. The community forest farmer respondents on site research mature majority in the range of 41-50 years old. The level of education respondents mostly only to elementary schools. In general the community forest farmer has a sideline job in addition to working on their forest field. Farmers in this area have a household incomes larger than level its expenditures, so they are on surplus condition. From the expenditure, allocation largest farmers used to terms of food. The community forest have a very important contribution in the structure of household income of farmers. By using the Sajogyo’s poverty line, more than three quarters of respondents the community forest farmers are above the poverty line or are able to meet the minimum basic needs. The condition is quite encouraging motivation

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.
