Underground utility mapping is important for extracting underground utility information such as electrical and telephone cables, gas pipes, drainage pipes and water pipes. Electromagnetic Location Surveys (EML) and Ground Penetrating Radar (GPR) have been widely used for mapping underground utilities at certain depths and refined utility characteristics. If it involves certain soils such as involving soils that are harder than usual, there is a possibility that the waves transmitted by the GPR are slower as compared to softer soils. Even the moisture rate on the soil also affects the GPR image. This study was conducted to find out how these two equipments are used with reference to the accuracy of hyperbolic images in GPR Radargram. The methodology carried out is by utility installation detection work and marking of detection information using EML and GPR by taking several images using the same frequency in the same area which is located in Perumahan Makmur Penor Utara Jaya (PUJ) using GPR model equipment (Leica DS2000), GPS (Topcon Hyper V) and EML (RD8100). Thus, the analysis found that appropriate conditions was when electrical cables can be detected more easily by using the clamping method which used the "peak" mode at frequencies of 8KHz - 33 KHz for EML devices and for GPR. The use of high frequencies (1GHz or more) is more suitable at making detection work for smaller utilities, in line with the formula 0.1*λ, where λ is the wavelength. Therefore, the results of this study are very important for quality improvement during data collection work as well as an increase in the production of high-quality underground utility maps.

Assessing depth of utility in different soil moisture conditions require good research. Moreover, different soil moisture conditions produce depths that are not the same as one another. The information of underground utility such as depth is very important to avoid damage towards utility during excavation process. Therefore, this study was conducted to assess the depth recorded by the (GPR) equipment in different soil condition in terms of soil moisture. The first objective of this study was to determine the soil moisture level for three different soil conditions. Next, this study evaluated the depth accuracy produced by the GPR equipment with the different soil moisture level such as dry, semi-dry and wet. Different soil moisture conditions were determined by the sampling of the three soil conditions. These samples were taken and tested using speedy soil moisture tester equipment that provided the percentage of soil moisture content. Next, the depth of utility was taken at the three soil moisture conditions and an assessment was made. The shape of hyperbolic on the radargram was generated from the equipment and was used to assess the accuracy of the depth. The information from this study is very useful to underground utility users which can help the development of the country in general. It also benefits the improvement of the preparation quality of underground utility mapping.

Learning Management System (LMS) is a software application or web-based technology that is used to develop, implement, and evaluate a specific learning process. KYP has implemented an e-Learning Management System (e-LMS) using Moodle since early 2021. The main features already implemented in this e-LMS is course details and it should also support the communication process between lecturers and students where currently, the KYP e-LMS lack of. Usually, students will ask the same question to their lecturer in person and cause the lecturer to have to give the same answers repeatedly. This results in a waste of time for both parties in answering and receiving answers. To overcome the problem, there is a need to replace the manual way of getting answers to any kind of academic or course related questions repeatedly. The main objective of the project is to develop an intelligence Chatbot which can help students finding academic related information without the need to ask their instructors or spent more time browsing menus in e-LMS. E-LMS has been developed based on Rational Unified Process (RUP) approach. In this project, the Moodle system is fully implemented by integrating with Kommunicate, one of the Cloud software and Dialog Flow, which is a chatbot plugin system connected with Google Could Platform. An AI Chatbot able to interact with students and can provide answer to students' queries instantly despite of the place, date and time zone of the student as well as enhances interaction which provides a feel of support to the students.
学习管理系统(LMS)是一种软件应用程序或基于web的技术，用于开发、实施和评估特定的学习过程。自2021年初以来，KYP使用Moodle实施了电子学习管理系统(e-LMS)。这个e-LMS中已经实现的主要功能是课程细节，它还应该支持讲师和学生之间的沟通过程，这是目前KYP e-LMS所缺乏的。通常，学生会亲自向讲师提出同样的问题，导致讲师不得不反复给出同样的答案。这会导致双方在回答和接收答案时浪费时间。为了克服这个问题，有必要用人工的方式来代替反复获得任何学术或课程相关问题的答案。该项目的主要目标是开发一种智能聊天机器人，它可以帮助学生找到与学术相关的信息，而无需询问他们的导师或花更多的时间浏览e-LMS的菜单。E-LMS是基于Rational统一过程(RUP)方法开发的。在这个项目中，Moodle系统是通过集成Cloud软件之一的communication和Dialog Flow来实现的，Dialog Flow是一个与Google Could Platform连接的聊天机器人插件系统。人工智能聊天机器人能够与学生互动，无论学生的地点、日期和时区如何，都可以立即回答学生的问题，并增强互动，为学生提供支持的感觉。

This paper is focusing on the Engineering Mathematics course that was conducted on an online platform due to the Pandemic of Covid-19. Mathematics instructors are being forced to digitize their course materials, such as videos of lecture topics over the Internet, but lack a detailed survey that addresses how students interact with course content, the tools available during class, and the available equipment at home. This presence challenge has been encountered through before and after class surveys to close the gap on the abovementioned issue through online learning. Throughout this study, the needs of students of the various departments involved were taken into account for the calculation of their satisfaction feedback that was investigated. The survey results also indicate that the problem of Internet coverage over time no longer exists for most students. Only the result of audio equipment instability due to the non-standard good quality of the equipment used during the online learning course was rated 18.3% out of 100%. The engineering mathematics content was delivered as planned and no critical learning issues were identified.

Alpinia purpurata (Halia Bara) is a perennial herbaceous plant with virtually identical qualities to common ginger, but with smaller and more pungent rhizomes. It is widely known for ornamental purposes and is also applied in the medicinal field. Extraction of essential oil and hydrosol of Alpinia purpurata can be done through the hydro distillation method. The essential oil contains α-pinene, β-caryophyllene, geranial, neral and β-pinene that contribute to medicinal values while hydrosol's chemical components are yet to be identified. Hence, the primary objective of this study is to use the hydro distillation method to identify the chemical constituents and functional groups of active chemical compounds present in Alpinia purpurata's rhizomes hydrosol. Hydro distillation is also done at different heating temperatures and distillation times to see what influence temperature and distillation time have on the components and active compounds in the hydrosol. The powdered sample is used for extraction at 60°C, 80°C, and 100°C, with distillation periods of 1, 1.5, 2, and 2.5 hours. Burette is used to extract essential oil from the hydrosol. To further investigate the hydrosol, gas chromatography-mass spectrometry (GC-MS) and Fourier-transform Infrared Spectroscopy (FTIR) are utilised extensively. The major chemical constituents detected in Alpinia purpurata's hydrosol at 100°C for 2.5 hours of distillation time include 1-Dodecanamine (40.08 %) and functional groups present are O-H, N-H, C-H, and C=H stretching, according to GC-MS and FTIR data. The increased heating temperature and distillation time caused the denaturation of substances in the extracted hydrosol. The chemical constituents present in hydrosol are greatly different from the chemical constituents that are present in essential oil qualitatively and quantitatively.

Oroxylum Indicum (Indian Trumpet Flower) or called Bonglai in Malay is a medicinal plant widely used, especially in the Indian medicine system. Oroxylum Indicum can be extracted by the hydrodistillation method to obtain the essential oil and hydrosol. Nevertheless, the chemical constituents of the hydrosol of the leaves are yet to be determined as hydrosol is always discarded, leading to the wastage of products. Thus, this study investigated the chemical constituents of Oroxylum Indicum leaves hydrosol extracted by hydrodistillation by varying temperatures and determined the functional groups of the active constituents in the leaves for the benefit and usage in pharmaceutical industries. Hydro distillation is carried out at different temperatures to study the effect of temperatures on the active compounds in the hydrosol. The hydrosol sample of the leaves will be extracted by hydrodistillation method at temperatures of 50℃, 70℃ and 80℃ and separated via rotary evaporator, and later analyzed by GC-MS and FTIR analysis. This study will help us to identify the value and amount yield of the chemical constituents of Oroxylum Indicum leaves hydrosol which will be able to determine whether it will have significant values equal to the essential oil. From FTIR analysis, the functional groups for all samples are the same which are O-H stretch, H- bonded, N-H stretch and C=C stretch. The chemical constituents of Oroxylum Indicum hydrosol were determined by GC-MS analysis. The major components of hydrosol produced at 50℃ are squalene (10.44%), 2ethylehexyl palmitate (8.56%), palmitic acid (7.50%), and di-n-2-propyl pentyl phthalate (1.69%), and at 70℃ is acetic acid (5.88%) only, while at 80℃ are only traces components respectively. This is due to most compounds contained may be decomposed during the preparation of samples prior to both analyses also the efficiency of the system and procedure during the extraction.

The current interest in minimizing the use of inorganic fertilizers and the increasing demand for the combined action of beneficial microorganisms and agricultural wastes is considered to have a positive impact on soil, crop productivity and sustainable agriculture. The objective of this study was to prepare a series of combinations of empty fruit compost (EFBC) and burnt rice husk (BRH) as carrier materials for selected nitrogen-fixing bacteria, evaluate their suitability, and determine the ability of the inoculated EFBC-BRH carrier materials. Different ratios of EFBC and BRH were used to prepare the carrier materials for the selected N₂-fixing bacteria, namely strains Sb35 and Sb42 of Bacillus sp. Both coarse and fine EFBCs were used for the preparations. The suitability of the combinations of EFBC-BRH as a bacterial carrier was tested by inoculating the different ratios of organic material combinations with the N₂-fixing bacteria and incubating them at room temperature for eight weeks, after which the effects on the bacterial population, pH, moisture content, and contaminants were determined. The results showed that the fine-textured EFBC-BRH carriers’ formulation (T5 to T8) were better carriers compared to the formulation of coarse-textured EFBC-BRH carriers (T1 to T4). The inoculated carrier T6 (1 fine structured EFBC: 1 BRH) showed the best response with an increase in Sb35 and Sb42 populations of 7.34% and 7.47%, respectively. In conclusion, T6 as a carrier material for Sb35 and Sb42 is suitable to be developed as a biofertilizer.

Task management systems are usually used by the project development teams to track their tasks from beginning to end, delegate subtasks to teammates, and set deadlines to make sure projects get done on time. It helps individuals to work more productively and efficiently. The same concept can be applied to students who have to perform group assignments but are located remotely from each other due to the closure of educational institutions because of the Covid19 pandemic. It is difficult for a student to divide group tasks since they only meet each other virtually through online classes with limited time. The objective of this project is to produce a web-based student task management system that can help UCYP students in managing their assignments and (to better manage the tasks assign) so they will not pass the deadline. The system has task tracking and recommendation features that help the student to manage their tasks easier and can decide the most important or critical task to do first. Student Task Management System implementing the Agile methodology in system development using JavaScript frameworks for both frontend and backend. The front-end is developed using Next.js and TypeScript while the back-end uses Node.js and GraphQL. The back-end itself will connect to the MongoDB database stored in the cloud using the MongoDB Atlas. This system implements authentication using the help of Firebase authentication which makes it easy for users to log in using their Google or Facebook accounts. The Web-based Student Task Management System was able to solve the problem of managing students’ tasks and making them become more productive and efficient in their studies.

A wheel hub retainer tool is a tool used to facilitate maintenance and drive shaft replacement. The drive shaft will suffer from wear and tear as the age of a car increases and the driving style is relatively rugged. on the side of the road. The method of opening the drive shaft nut manually requires a special tool as a hub retainer when the nut is opened so that the hub will not also rotate in the same direction as the nut rotation. The absence of special tools to hold the hub when opening the drive shaft nut led to the existence of various techniques and ways to open the drive shaft nut by mechanics. However, it is feared that this situation could cause damage to other components such as broken or bent bold studs that could slow down maintenance work or drive shaft replacement. The conceptual design for designing this tool involves a morphology chart and design selection based on Weighing Result Matrix Table. There are four design concept options that have been studied. Based on the selection of the best concept, a selected design concept involves five components that can be stitched together. As a result of this study, a concept design has been produced with the appropriate dimensions.
