SHORELINE MAPPING OF TELUK NIPAH USING DIGITAL SHORELINE ANALYSIS SYSTEM (DSAS) IN ARCGIS WITH TIDAL CORRECTION
Authors: Yong Ng Yee , Teh Hee Min , Balogun Abdul-Lateef Babatunde
Published: February 2024

Shoreline characterization using remote sensing technologies is a useful tool to determine the historical shoreline changes of a specific coast. Tidal variation is one of the important factors that should be considered in the shoreline mapping exercise. However, the tidal correction has often been neglected due to the need to access the historical tidal data series for the study site. As a result, the accuracy of the shoreline mapping without tidal correction is ambiguous. Hence, this study aims to establish the historical shoreline mapping of Pantai Teluk Nipah, Pangkor Island, Malaysia, with a tidal correction, using ArcGIS software. For 30 years of the study period, Landsat satellite imageries were processed via ArcGIS to quantify the shoreline change rate. Based on the previous shoreline mapping study without the tidal correction, transect 23 of Pantai Teluk Nipah has undergone severe erosion where the erosion rate is up to –6.83 m per year. With consideration of tidal correction, the shoreline erosion rate at the same transect has reduced to –3.87 m per year, which is consistent with the current beach condition at Pantai Teluk Nipah.

EXPERIMENTAL STUDY OF SOLANUM TUBEROSUM WASTE AS DRILLING FLUID ADDITIVES
Authors: Suaib Shazriana , Md Yusof M Aslam B , Ibrahim M Arif
Published: February 2024

Environmental consideration is essential during the drilling process in oil and gas development. However, the existing additives used in Water-Based Mud (WBM) are unable to create an efcient, entirely eco-friendly drilling fuid system. At the same time, Solanum Tuberosum Russet Burbank Waste (STRBW) which ranks as the second most produced food waste, shows a potential to be used as an environmentally friendly additive. In this experimental work, full-set rheological measurements under fresh and aged conditions and the fltration properties of STRBW were investigated in diferent concentrations; 1.2 wt%, 1.4 wt%, 1.8 wt% and 2.2 wt%. The analysis was conducted according to American Petroleum Institute RP-13B-1 Standard. The result was compared with a commercial WBM additive, Polyanionic Cellulose Low Viscosity (PAC-LV). The characterisation of STRBW was performed through Thermogravimetry Analysis (TGA), Field Emission Scanning Electron Microscopy with Energy dispersive X-ray (FESEM-EDX) and X-ray Difraction (XRD) analysis. The results showed that the microscopic appearance of STRBW was irregular and had rough. STRBW was degraded at 287°C, and it consisted of Carbon (C), Oxygen (O), Potassium (K), Calcium (Ca) and Magnesium (Mg). From XRD spectra, the existence of B-type starch was identifed in STRBW. To sum up, PAC-LV showed better rheological and fltration performance than STRBW at the same concentration. However, the performance of STRBW was enhanced as the concentration of STRBW increased up to 1.8 wt%. Other than decreasing the quantity of non-biodegradable waste thrown to the environment, these fndings indicated that STRBW has the potential to be utilised as a substitute for several standard chemical additives in the industry, such as polymers and fuid loss agents.

INVESTIGATION OF CLAY STABILIZER POTENTIAL FOR HIGH CLAY CONTENT FORMATION
Authors: Mohd Nazri Nur Khairul Bariyyah , Md Akhir Nur Asyraf
Published: February 2024

Clay swelling has been studied for decades due to its damaging problem in the reservoir. It has caused permeability impairment due to blockage at the pore throat and reduction of the available pore spaces in the reservoir. The past few decades have seen rapid development of clay stabilizers to treat clay minerals near-wellbore region areas. However, there a limited study investigating the potential of clay stabilizers to prevent clay swelling throughout the reservoir. The present study aimed to investigate the potential of potassium chloride (KCl) and Poly-diallyldimethylammonium chloride (PolyDADMAC) as cationic clay stabilizers to mitigate the clay swelling phenomenon throughout the reservoir. This study conducted a series of free swelling tests on bentonite with varying brine salinity and clay stabilizer concentration. In addition, the rheological properties of KCl and PolyDADMAC were measured at 24°C and 98°C and at a 7.34 s–1 shear rate to determine its flow potential throughout the reservoir. The results showed that 0.3 wt.% to 1.5 wt.% of KCl and PolyDADMAC were able to control the expansion of bentonite immersed in an aqueous solution, with PolyDADMAC has shown excellent performance, whereas the bentonite expansion in PolyDADMAC solution is significantly lower than KCl. This result is driven by the fact that PolyDADMAC has greater amounts of cationic charges to neutralize abundant negative charges on clay mineral surfaces. Furthermore, the viscosity of 0.3 wt.% to 1.5 wt.% of KCl and PolyDADMAC at 24°C and 98°C recorded is low, which is 0.25 cP to 1.45 cP and 0.83 cP to 2.32 cP respectively. This low value proves its potential to be penetrated throughout the reservoir, not limited to near the wellbore region only.

Authors: Ponnusamy Barath , Hussin Hilmi , Mokhtar Ainul Akmar , Muhammad Masdi
Published: February 2024

Raw mix design refers to the raw materials' quantitative proportions to achieve clinker with the desired chemical and mineralogical composition. The existing method used to formulate the raw mix design is based on iterative laboratory trials, which is time-consuming and heavily relies on the chemist's experience. Considering the negative environmental impacts, optimizing the raw mix design has become one of the major concerns among the cement players. Thus, the objective of this research is to optimize raw mix design with minimum cost while satisfying the critical clinker quality control targets. This study explored the Linear Programming (LP) model to achieve the objective. A Series of mathematical modeling was developed to relate the decision variables, raw mix and fuel mix design and the clinker chemistry. Bogue calculation is then applied to correlate the oxides from both raw mix and fuel mix to the phase content of C3S, C2S, C3A and C4AF in the clinker. The ratio of the clinker phases would be Lime Saturation Factor (LSF), Silica Ratio (SR) and Alumina Modulus (AM), which are used to determine the quality of the clinker, were defined as the main constraint. Limitation in the plant design, such as the number of dosing weighers, is also considered programming constraint. A case study was performed with eight types of raw materials consisting of Limestone, clay, sand, alternate material and additives to evaluate the LP model. Based on the GRG Nonlinear LP simulation, the optimized raw mix design was achieved at the cost of RM 6.845 per tonne composed of, 85.03% of Limestone, 0.9% of Clay 1, 12.6% of Alternate Material 1 and 1.47% of Additive 2. The obtained results prove that the developed LP model can minimize the raw material cost save analysis time, and provide flexibility in the raw material selection process without the need for actual trials.

THE STUDY OF THE EFFECT OF TEMPERATURE AND PH VALUE ON ADSORPTION CHARACTERISTICS OF UREA BASED SACRIFICIAL AGENT IN CLAY MINERALS
Authors: Andi Radi Andi Mohd Syaiful , Idress Mazlin , Redzuan Farah Rosmaniza
Published: February 2024

The Enhanced Oil Recovery (EOR) process has grown within the time oil exploration was conducted, and many recovery methods were invented to maximize production. One of the promising recovery techniques is carbon dioxide (CO2) flooding. However, CO2 flooding has its disadvantages where due to different mobility and heterogeneity between CO2 and reservoir, the sweep efficiency is reduced because of gas channelling and viscous fingering. Thus, the application of surfactant is introduced to solve the problem. But, by using surfactants in CO2 flooding, loss of surfactant to the formation is observed. Due to this setback, the cost of the EOR process increased significantly as more surfactants must be injected due to the loss. To reduce surfactant loss, sacrificial agents are introduced within the application of surfactant in CO2 flooding. The sacrificial agent would be adsorbed onto the clay minerals instead of surfactants. However, the application of sacrificial agent needs to be optimized to ensure a more cost-effective process. Therefore, this study, the adsorption rate of urea-based sacrificial agent in montmorillonite and kaolinite was tested under different pH values and temperatures using a UV-Vis spectrometer. Through the adsorption test, it is observed that the adsorption rate of urea is higher in montmorillonite than in kaolinite. The adsorption rate of urea in montmorillonite and kaolinite are optimized in high-temperature alkaline environment with 1.50 mg/g and 1.46 mg/g of urea adsorbed, respectively.Keywords: CO2 flooding, montmorillonite, kaolinite, sacrificial agent, urea, adsorption rate

Published: February 2024

Hydrological data in the form of stream flow is very scarce in most developing countries. This affects the planning and management of urban watersheds. Therefore, it is necessary to estimate peak discharge from rainfall using hydrologic models based on some measurable watershed characteristics. This study aims to model the rainfall-runoff process from a typical urban watershed using Hydrologic Engineering Center Hydrological Modeling System (HEC-HMS) software. The catchment basin has a total area of 21.91 km2, and a dendritic stream system. Soil Conservative Services (SCS) Curve number was used for getting excess rainfall from total rainfall, SCS dimensionless unit hydrograph for converting the excess rainfall to direct runoff and Muskingum for the channel routing. The rainfall-runoff simulation was conducted using six (6) rainfall events. Model calibration and validation were done using optimized parameters and the result shows a reasonable fit between the observed and simulated hydrograph. The model result has an RMS error of 1.5 m3/s, and a Nash-Sutcliff of 0.585. It is concluded that the model can be used to predict runoff from rainfall with reasonable accuracy. The result can be used for watershed planning and management.Keywords: HEC HMS, rainfall, runoff

Influence of pH On The Wettability of Carbonate Rocks for Carbon Dioxide Sequestration in Deep Saline Aquifer
Authors: Foong Khaw Chi , Chee Wee Sia , Md Yusof M Aslam
Published: February 2024

The escalating carbon dioxide (CO2) emissions have precipitated climate change, underscoring the urgent need for innovative solutions. Carbon Capture and Storage (CCS) represents a groundbreaking technology to mitigate carbon emissions by capturing CO2 and depositing it deep within reservoirs. This study focuses on the storage aspect of CCS by scrutinising reservoir properties. A pivotal factor influencing the geological storage of CO2 is the wettability of the CO2 /rock/brine system, which is intricately linked to the contact angle. However, previous research has indicated that pH can significantly influence the wettability of this system. Acetic acid, a prevalent organic acid in the petroleum industry, is commonly encountered and serves as a means to modulate pH. This experiment investigates pH variations, ranging from 3 to 7, through the introduction of acetic acid, while maintaining a salinity level of 30,000 ppm. Additionally, the type of rock mineral plays a crucial role in these findings. Therefore, this paper emphasises carbonate rocks, with a particular focus on limestone composed primarily of calcium carbonate (CaCO3). The experiment is conducted under elevated supercritical conditions, encompassing pressures of 10 MPa and 15 MPa, along with temperatures of 305 K and 323 K. Equilibrium contact angles are determined by measuring receding and advancing angles using the Vinci IFT 700 instrument under supercritical conditions. The results reveal a consistent trend wherein contact angles decrease as pH, temperature, and pressure increase, indicating a shift towards a water-wet system at higher pH, temperature, and pressure levels.Keywords: Carbon Capture and Storage (CCS), Wettability, Contact angle, pH, Acetic acid, Salinity, Carbonate rocks, Limestone, Supercritical conditions

Acute Respiratory Distress Syndrome (ARDS) occured in drowning patients in both fresh or salt water. This is a consequence of aspiration of fluid into the lungs. This condition can be made worse by the possibility of hypothermia, arrhythmia, or neurological impacts as a result of anoxia. A male, 16 years old, 60 kg without comorbid was drowned in a well, came on referral from a another hospital, he was admitted to the ward for 2 days. The patient arrived in emergency room and the patient is in respiratory failure state and ARDS. This patient was given intubation in the emergency room, after this patient is stable he was transfered to ICU. In the ICU, the patient was given mechanical ventilation therapy on 4th day and then he was given weaning gradually, on 7th day the patient was given extubation.
In general, treatment outcome of drowned patient really depends on how effective and fast the maangement of the respiratory distress in the incident location and until taken to hospital. Mechanical ventilation therapy follows the general ARDS management pattern, using PEEP and lung protection strategies. Monitoring and caution is needed during the weaning process to prevent recurrence of pulmonary edema and re-intubation.

So, for our daily life, we need to make sure about having clean water. Contaminated water can cause high-risk diseases for human beings sometimes it could be a reason for a person to die. Illnesses like Hepatitis, Cholera, Diarrhea, etc. are caused by contaminated water which could affect other people easily. Today there are several methods to get access to clean water, the methods used for water purification include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Trusted technology for water purification is Nanofiltration(r-GO) technology and Reverse Osmosis (RO). GO technology has attracted many researchers because of its unique hydrophilicity properties and its cost-effectiveness in mass-scale production. The r-GO membrane is one of the nanofiltration technologies that has the advantages of partial removal of monovalent ions, low process osmotic pressure, low operating pressure Energy saving, and other advantages.
Microcontroller-Based Automated Paddy Drying System for Enhancing Rice Production Efficiency
Authors: R. Bermoy Lyndon
Published: February 2024

Paddy drying is an essential step in the rice production process as it determines the final quality of the rice. Conventional methods for drying paddy are often labor-intensive and can be hindered by external factors such as weather. Our research suggests the implementation of a microcontroller-based automated system to improve the efficiency of the drying process. The system uses a microcontroller to oversee and manage the drying process to ensure that the paddy is dried to the ideal moisture level. The temperature and humidity in the drying chamber are manipulated through regulating the airflow and water vapor to control the drying process. The system also includes sensors to monitor the temperature and humidity in the drying chamber and the paddy in real-time. This system is expected to considerably enhance the efficiency of the paddy drying process and the quality of the final rice product. The system has been tested and validated using a sample of paddy, and the results demonstrate its capability to dry the paddy to the desired moisture level accurately and efficiently.

THE ROLE OF EXPANSION STRATEGIES IN THE GROWTH OF MTN NIGERIA, A CASE STUDY
OF MTN NIGERIA, DAMATURU BRANCH, YOBE STATE.
Authors: Adeola Adeyemi John
Published: February 2024

Although the mainstream of the investigations that study expansion strategies focus on expansion strategies from the standpoint of theoretical formulation and growth as per external and internal, little attention has been paid to the growth from perspective of the point of implementing organizational strategies formulated especially within the telecommunication industry like MTN. Therefore, this research aims to examine the extent at which expansion strategies affects the growth of MTN; ascertain the
challenges faced in the implementation of the expansion strategies by MTN and examine the relationship between expansion strategies and the growth of MTN. This is achieved by using descriptive research design in order to generalize the findings to a larger population and it is more precise and accurate since it involves description of events in a carefully planned way. A stratified random sampling is used in the
study as 123 staff of MTN in Damaturu, Yobe state across four MTN offices collected questionnaires, while 120 was retrieved. The study finds with strong evidence that expansion strategies has a positive effect on the growth of MTN. Regression Analysis of Variance (ANOVA) table showed F-value of 4.196 and P<0.05, and it implies that the regression is significant statistically, the extent at which Growth is dependent on Expansion Strategies is significant. Also, the study finds that the relationship between
concentration strategies, integration strategies and diversification; and growth of mtn is significant with 0.82, 0.78 and 0.87 (p<0.05). The study also finds that the inability to understand the peculiarities of a new market, such as the demographic, cultural, and economic factors that may affect the success of the expansion, funding and financial allocation, and setting up subsidiary and legal compliance could be very challenging in the course of strategizing for growth. The study recommends that MTN should develop
their products to meet the needs of the target market, allocate finances appropriately for priorities and also intimate staff on legal compliance and deliberate implementation of strategies for sustainable growth of the organization.
