Construction of a Measuring Instrument for Soil Organic Matter (SOM) Content Using Optical Spectroscopy. Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering. Cavite State University, Indang, Cavite. April 2015. Adviser: Engr. Michael T. Costa.
The study was conducted from October 2014 to March 2015 at Indang, Cavite to design and construct a measuring instrument for Soil Organic Matter (SOM) Content using Optical Spectroscopy. Specifically, it aimed to: l. design and construct a measuring instrument for SOM content using optical spectroscopy; 2. develop a software for measuring SOM; 3. capture and analyze through image processing technology measurement of the percentage content of the organic matter present in the sample;
4.test and evaluate the measuring instrument for SOM content using optical spectroscopy; and 5. conduct cost computation.
The system used a Visual Basic Programming Language to analyze and display the SOM percentage. The SOM measuring instrument was consist of camera, LED that produces UV light, power supply, and computer having a program which analyses image.
The design project was tested and evaluated through the comparison between the data gathered using the Loss of Weight on ignition method (LOI) and the SOM measuring instrument. The evaluation was conducted at the Material Testing Laboratory, Cavite State University (CVSU), Indang, Cavite. T-Test and correlation coefficient analysis were used to analyze the gathered data and results. It was proven that there was no significant difference between the data gathered from the two methods and there was a very high correlation between the two.
It was concluded based on the statistical results that SOM measuring instrument can read organic matter of the soil. The researchers recommend future researchers to include other soil composition readings and compare the SOM content measuring instrument to the commercially available laboratory instrument that was used in measuring SOM The total cost of the design project was PI 0,866
