00:00♪♪♪
00:11It's possible that the soil is dangerous after earthquakes, landslides, and others.
00:16But the soil is stronger and safer to monitor underground
00:20because of an innovation that won the National Winner
00:24at the James Dyson Awards this year.
00:26Come on, let's change the game!
00:28♪♪♪
00:32Ever wondered what's happening underground?
00:38That's the goal of our tech today,
00:40that can produce visual data from underground.
00:45Meet Ramon, short for Resistivity Acquisition and Monitoring Underground.
00:53Using sensors and electric current transmitters,
00:56it can get the soil resistivity or the capacity of the soil to transmit current.
01:02The brains behind the innovation are Joseph Aristotel De Leon
01:05and Department of Manufacturing Engineering and Management of Del Sol University.
01:10There are many things underground that we can't see with our eyes.
01:14We shouldn't neglect them.
01:17An example of this is groundwater pollution.
01:19If we drink or use water from our wells, it might be contaminated.
01:24Data on construction can also be used.
01:27Monitoring the strength of the soil after an earthquake and landslides.
01:33To collect data on the soil and measure the so-called soil resistivity,
01:40Ramon uses two main components.
01:43Let's start with the sensor.
01:46This is what we place on the ground or asphalt.
01:51While the transmitters,
01:53he installs them in places where current flows to inject electric current.
01:57It depends on what's underneath.
01:59By corresponding voltage, it responds to record.
02:03In a small sandbox,
02:05Aris showed us how it works.
02:08Dear viewers, if you notice what our waves will look like,
02:13first, the soil doesn't have enough water.
02:17We'll add water.
02:20That's it.
02:21The signal is getting bigger, right?
02:23Yes.
02:24The data from the sensors will go through data processing to make a time-lapse video,
02:31making underground monitoring more efficient.
02:34Great work indeed.
02:37That's why Aris's innovation
02:39is this year's national winner in the International Design Competition,
02:43the James Dyson Award.
02:45It's a big confidence booster to continue.
02:50Now, we're trying to develop the field site prototype.
02:56There you have it, Kapuso.
02:58An underground monitoring system
03:00that can be widely used for safety and risk reduction.
03:05For GMA Integrated News,
03:07I'm Martin Aviar,
03:08changing the game!
03:10It's a waste of food if it tastes bad because of salmonella.
03:14This bacteria detection
03:16was developed by some researchers at UP Diliman.
03:21Come on, let's change the game!
03:27Fever,
03:28cough,
03:29and stomach pain.
03:31You might be food poisoned.
03:33And that's possible if you eat meat and vegetables.
03:37And that's possible if you eat meat and eggs that are undercooked.
03:42According to one study,
03:44salmonella is the number one cause of food poisoning in the country.
03:49Last year alone,
03:50the number of salmonella cases increased by 42% or 13,000 in the Philippines.
03:55That's why aside from proper cooking,
03:57early detection is also important.
04:03The gold standard in salmonella detection
04:05lasts for 5 to 7 days,
04:07but our innovation today will speed it up to just 3 days.
04:13In 2021,
04:14the Department of Agriculture funded the Salmonella Lab Project
04:19headed by Dr. Wendell Rivera
04:21and Dr. Davin Adau of the UP Institute of Biology.
04:25They decided to create a more efficient method
04:28to detect salmonella.
04:30The problem with meat and meat products here in the Philippines
04:35is that there is no efficient method
04:37to check or detect the presence of salmonella.
04:42This is very important
04:43because this is the number one contaminant,
04:46a food-borne microorganism
04:48that causes food-borne disease.
04:51After 3 years of research work,
04:53they were able to create the LAMP assay,
04:56an efficient, accurate, and affordable salmonella detector.
05:01It comes with a die inside.
05:04After the reaction,
05:06it will be viewed under UV light with a positive result.
05:09More than 1,000 meat samples were used in the research
05:14to perfect the detector.
05:16Our original target is Hull Metro Manila.
05:20We will process the samples from the market.
05:23With the LAMP method,
05:24we were able to get a 100% detection rate.
05:27Everyone will start by getting a DNA sample of bacteria
05:31that has been there for 2 days.
05:33Once we get the DNA,
05:35we will put it in the LAMP assay.
05:37This is the heating of our samples.
05:42After an hour,
05:43we will know if the salmonella is positive
05:49based on the color.
05:51As you can see, it turned green.
05:53That means, from orange to green,
05:56the salmonella is positive.
05:58Using a blue LED light,
06:01the samples are glowing,
06:02which means the salmonella is positive.
06:06There you go, Kapuso.
06:07A game-changing innovation
06:09that will help food safety in the country.
