Wireless monitoring in harvests of coconut sap for production of coco sugar among the top researches presented in the USTP System Wide Research Summit

Coconut farmers may soon use wireless technology when they monitor the harvest of coconut sap in the production of coco sugar. Instead of the farmer climbing the coconut tree five (5) times a day to check if the sap is fermented and suitable for coco sugar, all he needs is a device to give him the necessary data that will notify him that the pH level of the sap is of acceptable value.

Sap collection in the production of coco sugar

Sap from the coconut used for the production of coco sugar needs to be at 6.01 to 6.09 pH. The sap with a lower pH than these will stale within 24 (twenty four) hours and is not viable for coco sugar production.

Process using the wireless monitoring device

The wireless device is attached to the sap collector to test the pH level of the collected sap. The data will be collected and stored in a database. The collected data will be displayed at the web page data logger. If the pH is of the right level, it will send a notification. This will make it convenient for the farmer.


Coco sugar has lower glycemic index (35) than white sugar (60-65) and doesn’t spike blood glucose and insulin like white sugar does. It is also a good substitute to other sugar or sweeteners.

Materials and design of the wireless monitoring device

This is one of the research presented by Vanessa Ybanez, Mirasol Augusto, Dennis Digal and Engr Miriam Bergado entitled Wireless Network Monitoring System for the Analysis of Coconut Sap’s Fermentation for the Production of Coco Sugar.

Best Paper for Stream C

Their research won the Best Paper Award and Best Abstract Paper Presentation in Stream C for Information and Communication Technology of the System-Wide Virtual In-House Research Summit last October 29-30, 2020 at the University of Science and Technology of Southern Philippines.

The researchers in Barangay Linabu, Balingasag, Misamis Oriental

The research was conducted in Barangay Linabu, Balingasag Misamis Oriental where farmers are engaged in coco sugar production. The wireless device can also monitor the acidity and temperature during the collection of the sap. The prototype device costs P3,000 to P4,000 and could be further developed to make it more affordable for the farmers.


Mirasol Augusto, together with the other researchers who are from the Computer Engineering department of the University of Science and Technology of Southern Philippines, believed that their wireless monitoring system can help farmers conveniently collect the coco sap for coco sugar production. Frequency on climbing of the coconut tree will be lesser and they can be more productive.

Actual design of the wireless monitoring device

The research team in their study noted that fermentation occurs a lot faster during day time with 5 hours compared to 8 hours during nigh time, a factor they attribute to the heat of the sun.

There are six (6) streams in the research summit which includes Food Security and Safety, Energy Sufficiency and Security, Information and Communication Technology, Industrial Development and Environment, Infrastructure and Transportation and GAD-related studies.


The keynote speaker of the research summit is Dr. Raymond Gerard Tan, Professor of Chemical Engineering and the Vice Chancellor for Research and Innovation of De La Salle University.

The summit was conducted virtually for the first time due to the pandemic. Dr Ambrosio B. Cultura II, System President of USTP said the academe needs to cope in the new normal and adapt. The research summit is part of the new brand of commitment of the University in its dedication to service in particular to instruction, research and extension.
