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.","PeriodicalId":255144,"journal":{"name":"Engineering, Agriculture, Science and Technology Journal (EAST-J)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121808087","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}

The UCYP’s Human Resource (HR) department record attendance and tasks done by employees during working at home by using word-processing based manual form. IT Department of UCYP has developed portal-based attendance system to keep electronic record of staffs’ attendance to cope with working from home condition. However, there is a need to create a more reliable attendance system. The objective of this project is to create an online attendance system using face recognition technique to overcome the problem faced by the HR department. The first step is to develop a mobile-based attendance system using face recognition technique to capture images of legal employees, store images in the database and provides function for clock in and out. Next, a web-based system is developed to generate attendance reports for personal and HR Department’s usage. Personal Extreme Programming (PXP) methodology has been used to develop the system.

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 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.

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.

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.

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.
