The implementation of Movement Control Order (MCO) during the COVID-19 pandemic in 2020-2021 has affected the production process of agricultural produce due to labour shortage. Agricultural workers were unable to come to work to care for crops. At the same time, the MCO has also given opportunities for budding farmers who began to show interest in gardening and making profit.

Starting from mid-2020, our school has established a small farm using fertigation farming to generate income. Fertigation, formed by two words – fertilization and irrigation; is a concept that relies on using the present irrigation line operating in existing field to inject plants with the desired fertilizers. From this idea, we have designed and proposed an automatic plant watering system, an innovative technology to make farmers work more efficiently and yield more profit.

The irrigation technics currently applied in farms are inefficient and causing excessive volume of water wastage. Artificial intelligence system that is applied in agriculture; also known as precision farming, may help farmers to efficiently control water usage thus produce a profitable crop.

Our project on automatic plant watering system named Mechatronic Fertigation, is a device system that transmits data from soil-moisture sensor to inform decisions about watering schedules besides supporting the efficiency of fertilizers in mass production of agriculture.

If moisture in the soil is considered at the optimum amount, plants can wealthily absorb water. The data obtained from the Mechatronic Fertigation helps farmers to increase their profit by learning how to take care of their crops and determining the ideal amount of water and fertilizer to use. By allowing humans to grow food in urban areas, this technology may have the capacity to reduce deforestation. 

The discharge of sewage and industrial waste into the world’s freshwater bodies has become an increasingly alarming issue with highly pervasive implications: waterborne diseases contracted by exposure to contaminated water result in 3.4 million deaths each year. This project thus aims to establish a cost-effective and accurate method of real-time water impurity detection, and to design an early-warning system for water-borne disease outbreaks in rural and low-resource settings. A novel software application that applies deep convolutional neural networks and sensing technology to the bacteriological and chemical evaluation of freshwater sources was developed. When synergized with IoT, the application can facilitate communication with individual households, local governments, and health authorities, streamlining environmental support and increasing the efficacy of purification efforts.

According to New Straits Times, about 100 farmers in Pinang Tunggal, Paya Keladi and Pantai Kamloon in Penang, are at risk of suffering major losses when there is inadequate water supply to irrigate paddy fields. My innovative plan is to harvest rain and runoff water by the usage of hi-tech solutions such as IoT to supply water in the underground storage automatically during drought. This idea does not only put an end to drought issues faced by the farmers but also increases the yield of food in my beloved country. It achieves 3 UN SDGs which are Goal2-Zero hunger, Goal13-Climate Action and Goal15-Life on land. I believe that my project will certainly create a better and greener future globally.

A Gamma Water Tank had been created to produce safe domestic water. Tests had been run to prove the safety of the Gamma Water Tank.
The raw water was first being treated with alum in screening tank. Then the water flow through the screening tank into the sedimentation tank. In the sedimentation tank the velocity of flow which carries the water horizontally will settle the particle at the bottom of the tank. The water then being aerated to remove dissolved gases. The water is then being filtered before being added with chlorine. All of the water samples go through some tests which are pH test, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).

Chlorine also can be harmful. Chlorine deals with bacteria by destroying it chemically, which is a trait it continues when it comes into contact with any organic material. When we bathe in chlorinated water, we are causing dry and brittle hair and flaky skin. If we get some into our eyes or lungs, they will become irritating. Chlorine is also capable of damaging plumbing fixtures and appliances, given time and strong enough concentrations.
This innovation was invented after conducting multiple science test on chlorine which causing cancer to thousands of lives in this world. The purpose of our invention is to prevent human from consuming excessive chlorinated water and dying from cancer.
