At first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^*$:
\[
f_k = f(x_k),\: x_k = x^*+kh,\: k=-\frac{N-1}{2},\dots,\frac{N-1}{2}
\]
where $h$ is some step.
Then we interpolate points $\{(x_k,f_k)\}$ by polynomial
\begin{equation} \label{eq:poly}
P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j}
\end{equation}
Its coefficients $\{a_j\}$ are found as a solution of system of linear equations:
\begin{equation} \label{eq:sys}
\left\{ P_{N-1}(x_k) = f_k\right\},\quad k=-\frac{N-1}{2},\dots,\frac{N-1}{2}
\end{equation}
Here are references to existing equations: (\ref{eq:poly}), (\ref{eq:sys}).
Here is reference to non-existing equation (\ref{eq:unknown}).

Research on Agricultural Informatics – Utilization of ICT to Improve The Agricultural Production System in Tropical Country
Environmental conditions is important factor affects the agricultural production system. In four seasons country like Japan, weather condition during cultivation can be fully controlled by utilization of greenhouse and environmental management. Microclimate manipulator can be managed automatically based on environmental evaluation. However, in tropical country like Indonesia, utilization of automatic control on greenhouse for agricultural production system is still rare because of the operational costs and the economic aspects. Thus, here we try to utilize the Information and Communication Technology (ICT) to improve the agricultural production system on tropical agriculture by implementation of regular environmental measurement using Field Monitoring System (FMS), Real-time environmental evaluation and information processing, and provision of decision support on farming activities. We realize that the incorporation of farmer’s knowledge and utilization of ICT would be able to support modern agriculture and also promising the progress on towards precision agriculture.
Deployment of Agricultural Information System – Installation and Utilization of Field Monitoring System on Agricultural Production in Yogyakarta, Indonesia
Agriculture is remaining to be a strategic sector in Indonesia. Besides its growth, there are also several challenges. Among others is the optimization of the agricultural production system. Practically, Indonesian farmers have improved their own cultivation technique and senses from their long-term accumulated experiences, includes knowledge about climate, weather, soil, crop type, etc. In this study, the author introduced an informatization agricultural supporting system, called the “Agri-eye” in order to improve agricultural production systems by integrating local knowledge and utilization of Information Communication Technology (ICT). Field monitoring system (FMS) is an automatic weather station installed in agriculture field to gather environmental data and forward it to the database server periodically, in addition, farmers can check their field environmental condition in real-time from a mobile phone or computer. Up to now, two FMS units have been installed in Sardonoharjo, Ngaglik, Sleman and Faculty of Agricultural Technology, Universitas Gadjah Mada, Yogyakarta as deployment test. In this article, installation and utilization of Field Monitoring System (FMS) on agricultural production will be explained. As the result, long-term environmental monitoring data (air temperature, air humidity and solar radiation) have been used as farmer decision support to prevent crops damages caused by extreme weather during cultivation. In the future works, comprehensive utilization of environmental information, local weather forecast, and control will be studied.

Penerapan Teknologi Inovatif dalam Industri Kelapa Sawit Ramah Lingkungan
Berawal dari share link mengenai seminar sawit yang diselenggarakan oleh jurusan teknik pertanian dan biosystem ugm di wall facebook, ada teman yang menanyakan terkait tema dari seminar, adapun tema yang diangkat pada seminar kali ini adalah “Penerapan Teknologi Inovatif dalam Industri Kelapa Sawit Ramah Lingkungan”, dan pertanyaan yang dilontarkan adalah apa sih teknologi ramahlingkungan yang di tawarkan?
seminar note:Agriculture and Integrated Production (IP) in Europe: The Almeria Case
[dropcap]W[/dropcap]inter 2012. Today i had opportunity to join special seminar in IT-Agriculture, held by Laboratory of Farm Management, my neighbor laboratory. The keynote speaker is Prof. Fernando Bievenido frrom Departement of Computer Language and Science, University of Almeria, Spain. He will explain his research entitled “Agriculture and Integrated Production(IP) in Europe: The Almeria’s Case”. In this note, I just try retell what I catch from his interesting topics.
Cooperation between all the agent was really the key point of implementation Integrated Production(IP)
Innovation is Important things
[dropcap]Y[/dropcap]esterday, I had opportunity to discuss with my Professor, related to research in Agriculture, especially ini his research interest, Agriculture Informatics. We discuss about technology and field application, as we know that Information and technology is common use in various field of science, perhaps technology was already given by technology developer and IT practitioners, but we have to improve that technology and enhance innovation to get the benefit of technology in specific application IT Agriculture. Innovation is keyword, he said..
