This paper presents the design of automatic watering system using sun tracking as an energy source .The objective is to design the automatic watering system for fruits grown in both areas without electricity. The solar panel can be moved along the direction of the sun cover an altitude - azimuth dual axis as an energy source of the system. The 20 longan trees are used in the experiment. The DC motors and the solar panel is controlled and rotated by the microcontroller to the position of the maximum light intensity. The watering system section will use a technique to measure the soil moisture sensors ECHO2-20 with real time PC based monitor system by Visual Basic Studio. As for the experiment results it was found that the energy stored by the developed solar tracker increased to 17.72 percent in comparison to a solar panel fixed installation. The watering appropriate soil moisture content is 12 percent and stops at 25 percent resulting for the garden moderators to save time and labor.

The objective of this research is to construct the appropriate forecasting model for the export quantity of concentrated latex by the three time series analysis methods which are Box-Jenkins method Winters’ multiplicative exponential smoothing method and combined forecasting method. Time series data from the website of Office of Agricultural Economics during January 1998 to February 2014 (194 values) are used and divided into two series. The first 182 values from January 1998 until February 2013 for the models prediction and the last 12 values from March 2013 until February 2014 for comparison the performance of forecasting models via the criterion of the lowest root mean squared error and the criterion of the highest correlation coefficient between existing values and forecasted values. Research findings indicated that for all forecasting methods that have been studied the most powerful method is the combined forecasting and the forecasting model is where and represent the single forecasts at time t from Box-Jenkins method and Winters’ multiplicative exponential smoothing method respectively.

The aim of this research is to review the environmental management to analyze the potential of sustainable management and to develop the strategies for developing the sustainable management of at Wat Takien Floating Market. The research is conducted at Wat Takien Floating Market Bangkuvieng subdistrict Bangkruay district in Nonthaburi Province with twenty local authorities including Temple abbot members of the Temple committee and market manager via observations interviews and questionnaires by using Descriptive Analysis Means Standard Deviations Factor Analysis and Canonical Correlation Analysis. The results were as follows: 1. Not far from Bangkok Wat Takien Floating Market is located inside Wat Takien temple area with a nice natural view across the canal. The community around the market have been well corporating with the temple. Visitors can enjoy shoping local product learning local traditional sightseeing temple architecture and making merit at the same time. The floating market is mostly manage by the market manager. In some point the management system is found not to be well arranged. To facilitate a lot of visitors plenty of toilets and many alternativers parking space will be provided. The products inside the market seems to be well known by serveral media. 2. The potential of sustainable management of Wat Takien Floating Market come from variety of strength and opportunity factors. The opportunity elements includes currect economic circumstance community around the market local houses along the canal side Bangkuvieng Canal geography while the strength factors composed of temple policies the way market mananger managing the participation of each members temple architecture inland walkway live Thai classical music band and a resonable price of local product. 3. The strategies for developing the sustainable management of Wat Takien Floating Market can be classified as follow; Strategy for developing the floating market along with Buddhist traditional Strategy of setting reasonable price for local goods and Strategy of boat trip activity. The suggestions were that the Wat Takien Floating market can be a lot improved by using the strategies for developing the sustainable management. In particular it can be done by rearranging the organization structure raising the corporate networks developing the market management systematically expanding an advertising channel Instralling the market banner to draw visitor attention improving the walkway along the canal side releasing regulations for on-boat food vendors promoting local dishes that can be found in a market hosting a fair and activity that related to Buddhist traditional providing boat trip activity creating social responsibility and environmental friendly activity along the canal side.

Department of drainage and sewerage (DDS) has realised in the flooding in Bangkok. Despite these issues the flood control centre has been established for water level monitoring as well as solving its issue in case of the water level in canal over-leveled using supervisory control and data acquisition (SCADA) technology in order to control the pumping station located throughout Bangkok. This regulation system is mainly categorised into two systems: Field Server and Canal Regulation. Consequently this article presents on Novel Water Level Sensing for the Canals in Bangkok with the advantage and disadvantage analysis in the informative-acquiring pattern from instruments together with the limitations of operation for improving measurement more precise reliable and most efficient.

This research aims to study the effects of blanching Khi Lek (Cassia siamea Lamk) flowers in brine in order to improve the qualities of Khi Lek flower tea production. The study comprised two factors: (1) two-time intervals for blanching: 3 and 5 minutes; (2) two concentrations of brine: 1% and 3% (w/v) and a control using Khi Lek flowers without blanching. The findings of the study stated as follows: blanching with different concentrations of boiling brine contributed to significantly different qualities of outcomed tea products in the aspects of moisture content aw color turbidity ascorbic acid content antioxidant activity and the observed sensory evaluation as compared to the control without blanching. Moreover the optimum blanching conditions consisted of blanching with boiling 1% brine for 5 minutes to obtain the best qualities of Khi Lek flowers tea product.
