Study on Plant Motion Measurement and Analysis Utilizing Computer Vision: Development of Automatic Plant Motion Analysis using Optical Flow

by

Plants, like other living things, have biological clocks that allow them to respond the changes in time and environment1). At day, plants do photosynthesis to produce carbohydrate such as sugar. While at night, plants distribute the stored the carbohydrate to grow leaves, stem flowers, fruits, and roots. Analysis of plant growth and motion at night … Read more

Development of Smart Cloud-based Irrigation Controller: Real-time Evapotranspiration Monitoring in Tomato Greenhouse

by

The smart irrigation controller is a controller that reduces water use by monitoring and utilizing site environmental information and applying the right amount of water. These controllers receive feedback from the irrigated system and adjust irrigation duration and/or frequency accordingly. There are generally two types of smart controllers: climatologically based and soil moisture-based. Climatologically based … Read more

Example of Latex page

by

[latexpage] 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\{ … Read more

Research on Agricultural Informatics – Utilization of ICT to Improve The Agricultural Production System in Tropical Country

by

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 … Read more

Deployment of Agricultural Information System – Installation and Utilization of Field Monitoring System on Agricultural Production in Yogyakarta, Indonesia

by

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 … Read more

Development of Real-time Change Point Analysis for Field Environmental Information in Agriculture

by

Prehension and evaluation of field environmental conditions are very important tasks in agriculture. To enhance the agricultural production system, an agricultural information supporting system ”Agri-eye” has been developed based on a cloud computing scheme. It consists of work recording, actuation and field environmental monitoring system. Regarding the environmental observation, monitoring nodes have been installed in … Read more
