However, incorrect watering and fertilizing may result in plants perishing, not flowering, or not thriving. Moreover, users also need knowledge in temperature and humidity to take care of specialized plants and have a longer life. The current lifestyle also limits the ability of the user to maintain their indoor plants. Therefore, this study aims to develop an IoT-based plant monitoring and watering system. This system seeks to water the plants based on schedule and user input automatically. The single, smart pot system comprises controllers and sensors to monitor plant growth and automatic watering and fertilizer. The sensors include temperature, humidity, and soil moisture sensors. The data is transferred through Wi-Fi to a smartphone application where all the data can be viewed. Additionally, the system will have a Graphical User Interface (GUI) that shows the plant's current conditions. The plant status in the GUI includes information such as temperature, humidity, and whether the light is on or not. Information like when the plant will be watered and fertilized is also displayed. Finally, the time when the light will be toggled on or off is shown as well.

Recently, some of the institutions adopted the use of dynamic QR codes for attendance monitoring. However, these systems are challenging to maintain and time-consuming. The student can easily manipulate signatures for attendance monitoring. Moreover, the QR code system requires the application on both the lecturer and student sides. The lecturer needs to set up the QR code while using the mobile app to use the system. Therefore, it is time-consuming and sacrifices several minutes at the beginning of each class. The student also sometimes has difficulty in using the app leading to manual data insertion. Therefore, this project aims to solve this issue by using the facial recognition system on a lecturer’s laptop to collect the attendances. This project requires the use of a webcam and MATLAB to perform facial image recognition. This work utilizes face detection algorithm in the MATLAB image processing toolbox to build a system that will detect and recognize the frontal faces of students in a classroom. Firstly, several images of students will be recorded in a database. Then, a GUI-based application automatically identifies a face and matches it with the database created. Lecturers will use the GUI on their laptops, and students will show their faces to the web camera for their attendance to be taken. The system was tested successfully where student face was successfully recognized and recorded in the attendance monitoring system. Only registered user faces will be detected.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115021110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Market of penetration of EVs in the current market is quite outstanding and has been increase drastically in the recent years. With the integration, development, and introduction of EV, it adds more challenge towards electrical engineer to identify, acknowledge the impact of EV in term of power quality issues like harmonics, voltage stability, etc. when the EV is connected to the grid system. Hence, it is essential for engineers to evaluate all potential grid impacts due to EV integration to ensure the grid operation is operating at optimum and safe condition without effecting any equipment. This paper will identify and investigate the effects of harmonics when EV is connected to the grid system and identify the most suitable method to mitigate the harmonics that occur due to the EV charging station. The scope of this paper is limited to 8 numbers of EV charging station rated at 100kW output. This paper will also be focusing more on power quality issues in context of harmonics distortion that occurs when the amount of EVs charging station is connected to the distribution system.

As of 2020, Malaysia has a MS 1525:2007 Building Energy Index standard of 135 kWh/m2/year. A lower BEI rating translates to efficient and energy saving environment of a building. Different techniques are being employed in the Energy Conservation Opportunities (ECO) to achieve the recommended standard in Malaysia. Different materials and structural design of low carbon buildings in Malaysia plays a vital role in determining the average BEI rating annually. The Green Energy Office (GEO) building in Bangi which was completed in 2007 has deployed many of its efficient and environmentally friendly technologies to produce a BEI rating of 30 kWh/m2/year, reducing a total of 360 tonnes of carbon emissions a year. The efficiently designed structures of these low carbon buildings utilize many different energy saving techniques like natural lighting, tilting facade, building orientation and insulated concrete roof.

Kampung Selarong mainly relies on diesel fuel for electricity generation because. Grid extension to this area is costly due to its location. Unfortunately, the usage of diesel–powered generators were expensive because of its high price, soaring levels of maintenance and operation. Diesel generators also was identified to cause harm towards the environment because it contributes to greenhouse gases, global warming, and abrupt climate changes. As a alternative to curbing the usage of diesel – powered generators, HRES was proposed in Kampung Selarong. This project aims to collect load power data around Kampung Selarong and feed those data into the Hybrid Optimization of Multiple Energy Resources software (HOMER) to get an in-depth analysis of the load power consumption in the village. Upon completion of data analysis, these configurations were compared to obtain desired configurations for a combination of PV, diesel – powered generators and battery storage system.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115343310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, water pollutions are a serious issue that needs to be solved. One of the actions that needs to be taken is to monitor the water quality regularly. However, many areas still used manual monitoring due to high cost of automatic monitoring system. Hence, this study aims to develop a low-cost and low-power water pollution monitoring system using a microcontroller and long-range wireless system (LoRa). The system monitors the water pollutions through pH and temperature sensor. Next, the data transmitted to a host PC wirelessly through LoRa communication. The data received will bs stored in a cloud with GUI. Moreover, the system equipped with a PV panel and Lithium-ion battery storage. This will allow the system to be deployed in remote areas with no power sources. The system performance on pollution detection and transmission distance were tested via several experiments. Several substances with different pH values were used simulate polluted water. Meanwhile, the data transmission was evaluated through several distance parameters. The results show the system successfully able to monitor polluted water with high accuracy and capable to transmit long-range data wireless. Hence, the system has efficient power usage through few numbers of sensors alongside LoRa that uses low power for communication.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131756483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
