Authors: Sari Zulia Wulan , Dira Ernawati
Published: December 2024

PT XYZ merupakan perusahaan galangan kapal terbesar di Indonesia. Sebagai galangan kapal terbesar, PT XYZ dituntut untuk menyelesaikan proyek pembangunan dan perbaikan kapal baru dengan cepat, sesuai dengan kesepakatan yang tertuang dalam kontrak yang disepakati antara pemilik kapal atau wakilnya dengan pihak galangan kapal. Dalam hal ini, perencanaan penjadwalan proyek memegang peranan yang sangat penting untuk memastikan setiap tahapan pekerjaan dapat diselesaikan secara efisien dan tepat waktu. Akan tetapi, jadwal yang dirancang sejak awal tidak selalu sepenuhnya selaras dengan pelaksanaan di lapangan, sehingga pekerjaan berpotensi mengalami keterlambatan dari waktu yang ditentukan. Keterlambatan tersebut juga terjadi pada proyek perbaikan KM STU yang dikerjakan oleh PT XYZ. Oleh karena itu, dilakukan penjadwalan ulang dengan metode Critical Chain Project Management. Dengan menerapkan metode CCPM, hasil penelitian menunjukkan durasi proyek selama 13 hari dengan tambahan buffer proyek selama 3,5 hari dan biaya sebesar Rp 266.000.000 yang mana sama dengan durasi normal atau kondisi awal. Namun apabila waktu buffer pada durasi CCPM terpakai penuh maka total biaya yang didapatkan akan bertambah menjadi Rp 304.080.000 atau sekitar 14,3% dari biaya CCPM tanpa buffer. Sementara itu, produktivitas pekerja dengan menerapkan metode Critical Chain Project Management mengalami peningkatan dibandingkan sebelumnya. Sebelumnya, rata-rata produktivitas pekerja sebesar 27,45/mandays. Kemudian setelah menerapkan metode CCPM, rata-rata produktivitas pekerja menjadi 54,89/mandays. Berdasarkan hasil penelitian, dapat diketahui bahwa metode Critical Chain Project Management lebih efektif dan efisien dibandingkan dengan metode sebelumnya. Sehingga hasil penelitian ini dapat digunakan oleh perusahaan sebagai acuan dalam merencanakan jadwal proyek perbaikan selanjutnya.
Ecological and Reproductive Behavior in Gonads of Bufo viridis in Rajasthan, India

Published: December 2024

Amphibians play a major role in both the environment and the economy. In addition to being strong predators of a variety of agricultural pests and insects that spread illness, amphibians also serve a beneficial role in reducing pest damage to crops and vegetables. Furthermore, toads are highly effective bioindicators of declining environmental conditions. According to life-history theory, trade-offs between survival and reproduction are essential for organisms to adapt to their various environments. According to our findings, there were notable demographic differences in Bufo viridis testes size.
As the relative testes size did not change with altitude or latitude, we were unable to identify any geographic trends that would account for the diversity in testes size. The size of testes is influenced by temperature variations, even if rainfall has no direct effect on testes size. This suggests that male reproductive investment is reduced in habitats with temperature fluctuations, which has significant conservation implications for amphibians. As they mature, ovaries get bigger and turn from pinkish white to black in color. Histological examination shows developing follicles in the female gonads of three months old and sperm cells in the male gonads.
IMPACT OF COMPARATIVE ADVERTISING ON QMOBILE’S BRAND IMAGE IN KARACHI
Authors: Khan Haris Bin Shabbir , Aslam Touqeer , Sami Abdul
Published: December 2024

The primary focus of this study is to scrutinize the efficacy of the comparative claim advertisement strategy, a practice prevalent in the sub-continent and particularly in Pakistan. Historically, this strategy was a dominant tool for creating brand awareness by establishing connections with a competitor’s product. However, over time, the proliferation of this approach has rendered it antiquated. While it may enhance brand awareness when coupled with distinctive attributes and cutting-edge technology, it becomes ineffective without product modernization. Drawing on information from ISI Thompson, I constructed a model with Brand Image as the dependent variable and product knowledge, competitive pricing, perceived similarity, and brand persona as independent variables. Utilizing a deductive approach and supporting my thesis with relevant published articles, I conducted surveys among North Nazimabad, Karachi students, targeting the struggling brand Q Mobile in the electronics consumer goods industry. Analyzing the gap in brand personality, a crucial element in customer-based brand equity, revealed the necessity of satisfying consumer needs, wants, and desires to foster brand loyalty. Statistical analysis using SPSS 20 on survey responses concluded that the comparative claim ad strategy should be abandoned in favor of an associative ad strategy for the long-term development of Q Mobile’s brand image.

Authors: Rehman Nazia Abdul , Arif Kashif , Nasim Shahzad , Siddiqi Zaibunnisa
Published: December 2024

This research evaluates the presence of twin deficits in Pakistan, as well as the relationship between twin deficits and key macroeconomic indicators such as GDP, interest rate, and money supply in the short and long run. The twin-deficit theory indicates a condition in which an economy's budget and current account deficits are both present simultaneously. On time-series quarterly secondary data from Pakistan from 1990 to 2023, the Autoregressive lag distribution (ARDL) model is used. The Augmented Dickey-Fuller (ADF) test was used to ensure the stationarity of variables at the level and 1st difference. According to the findings, Pakistan has a twin deficit in the short run as well as in the long run. The data also point to a significant link between the twin deficit with GDP and I.R., as well as the negative association between the twin deficit and M2. The conclusions may be useful to Pakistan's and developing countries' economic management in implementing their strategies. This research examines the long- and short-term associations between the twin deficit and gross domestic product. It ascertains the causal relationship between the twin deficit, money supply, and interest rate through the ARDL approach.

Published: December 2024

This paper investigates the profitability of investing in small and medium-sized companies in Pakistan's stock market. Recent studies have found a significant impact of firms' size on stock market price. This study investigates the effect of firm size on companies listed on the Pakistan Stock Exchange, as the price of small-cap stocks should represent the firm's profitability. Stock performance in January and July plays a key role in the relationship between firm size and stock price appreciation. The study uses Thomson Reuters DataStream data, first released in January 2007, and gives investors access to previously inaccessible market data. This data includes monthly updates on the closing prices of business stocks, the value of the KSE-100 indexes, and the size of the Market. Under the Panel data techniques, a fixed-effects model is used to investigate the relationship. The findings of this paper suggest a link between company size and stock performance. The study finds the negative impact of the size of a firm on Stock Market Performance in the Pakistani stock market. This suggests that investors place a higher value on small-cap enterprises. The study found comparable results in many previous studies. The main contribution of this paper is to provide an understanding of how firm size affects stock in Pakistan's stock market. Unlike previous studies, rather than analyzing each company individually, the study uses aggregate monthly data on excess stock returns from more than 300 to grasp the size premium precisely.
EXAMINING THE INFLUENCE OF MACROECONOMIC FACTORS ON ECONOMIC DEVELOPMENT IN PAKISTAN: A STUDY OF INFLATION, EXCHANGE RATES, TRADE DYNAMICS, AND FOREIGN DIRECT INVESTMENT
Authors: Ahmed Uzair , Muzammil Muhammad
Published: December 2024

This research considers the effects of the inflation rate, currency exchange, export, import, FDI, and economic development in Pakistan. This research surveys the economic development of Pakistan from 2001 to 2023, with inflation, exchange rate, export, import, and FDI as independent variables and economic growth as the dependent variable. Firstly, the study gives the group statistics of the variables, and it is conducted with the help of an Augmented Dickey-Fuller (ADF) test to assess the unit root of the variables. For the analysis of the connection between the variables, the Least Square method (including NLS and ARMA models) and Granger Causality tests are used. Therefore, it can be inferred that the Granger causality analysis is a one-sided causal connection between the GDP and FDI and the inflation rate. On the other hand, there is a bi-directional connection between GDP and the level of imports, as well as the exchange rate and GDP. However, there are no significant causal relationships between the other variables. On top of it, the results of the Least Square (NLS and ARMA) method propose that the inflation rate has a cardinal non-favourable impact on Pakistan's economy. On the contrary, the exchange rate, exports, and FDI also have a significant favourable impact on Pakistan's economic growth. These findings can help politicians to make effective policies for the stabilization of the macroeconomic environment and sustainable development in the country.

Dr Sumair FarooqVisiting Faculty Hamdard UniversityKarachi, Pakistan
Abstract
The worldwide monetary calamity that began in 2008 impacted numerous countries, including Sri Lanka. The issue significantly affected Sri Lanka's economy, particularly the modern area. This study aims to give an overall outline of how Sri Lanka's assembling area will charge following the worldwide monetary emergency. One of the principal powers behind Sri Lanka's economy is the modern area, which impressively supports the country's Gross domestic product and offers many individuals business valuable open doors. Manufacturing, building, and mining are only a couple of the subsectors that make up this industry. Every one of these sub-areas was seriously influenced by the monetary emergency, and this particularly affected how reasonably they could work. The drop sought after for its labor and products was one of the fundamental effects of the monetary emergency on Sri Lanka's modern area. Because of the emergency, global trade shrank, which diminished the interest in Sri Lankan products abroad. The modern area all in all was impacted by this drop sought after, with numerous organizations announcing significant income declines. The monetary emergency likewise significantly affected credit accessibility, which influenced how simple it was for organizations in the modern area to get funding. Because of the fixing of credit guidelines during the monetary emergency, it was trying for some organizations in Sri Lanka that relied upon bank advances and different types of credit to back their activities to acquire the subsidizing they expected to stay in activity. The monetary emergency not just brought about a decrease in popular and credit accessibility, yet it likewise uncovered production network defects in the Sri Lankan modern area. The emergency's effect on worldwide exchange exposed the country's exorbitant reliance on imports of natural substances and different data sources, which brought about deficiencies and greater costs.
FACTORS RESPONSIBLE FOR UNEMPLOYMENT IN PAKISTAN: A TIME SERIES EVIDENCE
Authors: Hasan Amber , Zaheer Rummana
Published: December 2024

The research intended to determine the factors responsible for increasing unemployment in Pakistan. The purpose has been accomplished by examining the yearly statistics of Pakistan over the time from 1970-2019. The explanatory variables used in the study are Foreign direct investment (FDI), Population growth, GDP growth, Inflation, and External debt. The stationarity of data has been inspected by employing Augmented Dicker-Fuller Test. Results of the unit root test indicate that some variables are stationary at a level whereas others are stationary at first difference. In the presence of diverse stationarity levels, the ARDL technique is considered to be the most appropriate approach in examining the long- and short-term association among variables. The empirical result indicates that FDI, Inflation, and Population Growth have an inverse relation with unemployment. The Phillip curve approach is employed to understand the relationship between inflation and unemployment. While GDP growth is shown to be positively linked with unemployment, which proves that in the case of Pakistan, Okun’s law does not hold any place.

Authors: Shahid Wajiha
Published: December 2024

Floods are regarded as the most catastrophic natural dangers globally owing to the greater intensity of the damage they cause. Understanding risk perception is essential for implementing the proper catastrophe risk mitigation techniques. Flood dangers in linked rivers with the downstream and upstream flow are caused mainly by glacier melting and repeated rainfall cycles. In the event of flood dangers, Pakistan saw the worst flash floods in 2022, which resulted in a 10 billion dollar economic loss and destroyed 2 million hectares of cropland. It harmed the nation’s 24 million inhabitants. Due to its location in an area prone to hazards and frequent flooding, Pakistan has been categorized as one of the world’s most hazard-affected nations during the past 20 years. To help flood victims meet their urgent social requirements, this paper discusses shared demands and the significance of addressing their sociological needs. For this reason, the planning, preparation, and execution of morally based and culturally sensitive post-disaster social care delivery are evaluated. Social workers and socio-political analysts have a joint obligation to play. The ability, opportunity, and speed with which people, families, organizations, and communities recover from the destruction that follows a disaster are given special attention.

Published: December 2024

Background. Post-stroke spasticity is a disabling impairment that negatively impacts walking performance and quality of life (QoL). It has been established that non-intrusive techniques like transcutaneous electrical nerve stimulation (TENS) have anti-spastic characteristics. Purpose. To identify the additional effect of TENS applied to acupuncture points on spasticity, walking performance and QoL in chronic stroke patients. Methods. A randomized controlled trial was carried out on thirty stroke patients from both sexes aged 45-60 years. They were randomly allocated into the study and the control groups, with 15 patients in each group. Patients in the control group underwent a designed physiotherapy program, while participants in the study group underwent the same physiotherapy program plus TENS on acupoints of the affected lower extremity. The measured variables comprised the Modified Ashworth Scale (MAS) for evaluating spasticity, the World Health Organization quality of life assessment instrument (WHOQOL-BREF) for evaluating QoL and the Biodex Gait Trainer for measuring the spatiotemporal gait parameters. Evaluation of all variables took place before and following intervention. Results. There was a statistically significant improvement of all measured variables in both groups post-treatment (p < 0.05) except for the MAS score for the control group which was non-significant (p = 0.65). There was a significant decrease in MAS score (p = 0.03) and a significant increase in walking speed, step length of the affected and non-affected sides, time of single limb support on affected leg and the WHOQOL-BREF scores of study group compared with that of control group post-treatment (p < 0.05). Conclusion. Transcutaneous electrical nerve stimulation (TENS) applied to acupoints could be an effective, safe, and cost-wise adjunct to a physiotherapy program in improving spasticity, walking performance and QoL in chronic stroke survivors.

Introduction. The analysis of a student’s environment is a collection of stressors of human being ecology field. Material, method. The research of body posture was carried out in a group of 65 students aged 7 years, by projection moiré method in 6 positions. Measurement of physical fitness was done by the Sekita test. Results. The restitution of the obtained results of postural traits of boys and girls between 2nd and 3rd, 3rd and 4th, 1st and 3rd and 1st and 4th measurements after loading on the left or right shoulder was analyzed. The relationships of the differences with the results of the Sekita fitness test were also studied. Conclusions: 1. There was no full restitution of postural features in the sagittal and transversal planes after the first and second minutes from removing the 4-kilogram weight of school supplies from the left or right shoulder carried boys and girls. 2. Due to the lack of full restitution of the value of postural features, the carrying of a 4-kilogram weight of school supplies on the left or right shoulder is not advisable for children aged 7. The obtained physical fitness does not support full restitution of the value of the features, which indicates its low level and immature corrective-compensatory process.

Authors: Marda Marda , Imro'ah Nurfitri , Novita Irene
Published: December 2024

The manufactured coconut classified under HS code 08011100 is available in either shredded or dried form. In 2022, this variety of coconut is projected to account for 8.68% of the export value of manufactured coconuts in Indonesia. While West Kalimantan has not yet achieved the status of the largest coconut exporter in Indonesia, coconut remains the primary commodity in the plantation sub-sector and significantly contributes to the Regional Original Income (PAD) of West Kalimantan Province. West Kalimantan, with a potential coconut plantation area of 94,204 ha and a growing array of processed coconut products, stands poised to enhance the value of its coconut exports. This study seeks to examine prospective market conditions by predicting the export value of coconuts in shredded or dried form, serving as a foundational strategy for enhancing the value of coconut exports. The ARIMA (Autoregressive Integrated Moving Average) model is employed to forecast the value of coconut exports (HS 08011100) for the upcoming 4 periods. During the process of identifying the best model, the ARIMA model (2,1,1) was selected, yielding a MAPE value of 26.63%. This indicates that the forecasts for coconut export values (HS 08011100) remain acceptable. The estimated coconut export value serves as a valuable planning reference for stakeholders aiming to enhance future coconut exports.

Two-year Results of an Emergency Department Night Shift Buy-out Program
Authors: Croteau Charlotte W. , Goldstein Joshua N. , Nentwich Lauren , Raja Ali S. , VanRooyen Michael , Baugh Joshua J.
Published: December 2024

Introduction: Emergency physicians have the highest rates of burnout among our physician peers, with prior literature suggesting clinician schedules can play a signiﬁcant role in burnout. We assessed our transition from a tenure- and age-based paradigm to an egalitarian, night shift buy-out program that allows schedule ﬂexibility for physicians at all stages of their careers. Methods: The night shift buy-out program was implemented in the emergency department (ED) of an academic, quaternary-care center that treats approximately 100,000 adult patients annually with 56 faculty emergency physicians. We sought to create a cost-neutral program, carefully balancing incentives between nocturnists and those wanting to reduce allotted night shifts. Ultimately, the program was designed to allow all faculty to buy out of any number of nights for $500 per night shift, with the funds generated used to increase nocturnist salaries. We analyzed two years of the program (July 2022–June 2024) to assess trends in night shift buy-outs, the primary outcome. We also conducted an all-faculty survey after the program’s ﬁrst year to gauge sentiments about the program. Results: Over two years, 22 faculty (42%) fully bought out of nights; an additional 10 (15%) bought out of some nights. By year two, the program could grant all faculty their preferred night-shift allotment. Faculty who bought out fully had worked longer in EM on average, worked fewer clinical hours per year, were more likely to be associate/full professors, and were less likely to be women. Nocturnists had the highest mean clinical hours of the four groups, had the lowest average tenure, and were least likely to be associate/full professors. A total of 86% of faculty responded to the survey, to which more than 80% of those buying out reported that reducing the night-shift burden was either “very important” or “critical for continuing in this job.” Conclusion: Our academic ED transitioned from a tenure- and age-based, overnight shift paradigm to an egalitarian buy-out program that allows physicians ﬂexibility at all career stages. This approach could improve career satisfaction and reduce burnout among emergency physicians.

Published: December 2024

Introduction: The utility of the three-part bedside oculomotor exam HINTS (head impulse test, nystagmus, test of skew) in the hands of emergency physicians remains under debate despite being supported by the most recent literature. Educators historically lack consensus on how speciﬁcally to teach this skill to emergency medicine (EM) residents, and it is unknown whether and how EM residency programs have begun to implement HINTS training into their curricula. We aimed to characterize the state of HINTS education in EM residency and develop a needs assessment. Methods: In this cross-sectional study, we administered a survey to EM residency directors, the themes of which centered around HINTS education perceptions, practices, resources, and needs. We analyzed Likert scales with means and 95% conﬁdence intervals for normally distributed data, and with medians and interquartile ranges for non-normally distributed data. Frequency distributions, means, and standard deviations were used in all other analyses. Results: Of 250 eligible participants, 201 (80.4%) responded and consented. Of the 192 respondents providing usable data, 149/191 (78.0%) believed the HINTS exam is valuable to teach; 124/192 (64.6%) reported HINTS educational offerings in conference; and 148/192 (77.1%) reported clinical bedside teaching by faculty. The most-effective educational modalities were clinical bedside teaching, online videos, and simulation. Subtopic teaching struggles with regard to HINTS were head impulse test and test-of-skew conduction and interpretation, selection of the correct patients, and overall HINTS interpretation. Teaching barriers centered around lack of faculty expertise, concern for poor HINTS reproducibility, and lack of resources. Leadership would dedicate a mean of 2.0 hours/year (SD 1.3 hours/year) to implementing a formal, standardized HINTS curriculum. Conclusion: Despite controversy surrounding the utility of the HINTS exam in EM, most residency directors believe it is important to teach. This needs assessment can guide development of formal educational and simulation curricula focusing on residency directors’ cited HINTS exam educational struggles, barriers, and reported most-effective teaching modalities.

Background: This study aimed to comprehensively analyze the biochemical blood indices of children with intussusception. Methods: A total of 8235 children with intussusception were included in this study, consisting of 5743 children with successfully reduced intussusception by hydraulic enema (the HE group) and 2492 children with surgical management after unsuccessful enema treatment (the SM group). The SM group consisted of the managed surgically with necrosis group (the SN+ group, n = 398) and the managed surgically without necrosis group (the SN- group, n = 2094). This study conducted a comprehensive analysis of 74 clinical and biochemical parameters in these children with intussusception. Results: Temperature, plateletcrit (PCT), mononuclear cell ratio (MONO%), monocyte count (MONO#), γ-glutamyltranspeptidase (GGT), direct bilirubin (DBIL), and C-reactive protein (CRP) increased gradually in HE, SN-, and SN+ groups and might be risk factors for further development of HE into SN- or SN+. The neutro cell count (NEUT#), neutro cell ratio (NEUT%), and white blood cell count (WBC) showed significant differences only in HE/SN+ and SN-/SN+ groups, which might be risk factors for intussusception complicated with intestinal necrosis in children. The prediction model composed of seven variables (i.e., NEUT#, platelet (PLT), albumin (ALB), β-2MG macroglobulin (β-2MG), glucose (Glu), uric acid (UA), and chlorine (Cl) was suitable for HE/SM. The average prediction accuracy of this model was 81.82%, and the area under the receiver operating characteristic curve (AUROC) was 0.87 (95% CI: 0.85 - 0.90). The prediction model composed of six variables (i.e., NEUT#, average hemoglobin concentration (MCHC), PLT, the total protein (TP), CRP, and urea (BUN) was suitable for SN-/SN+. The average prediction accuracy of this model was 87.93%, and the AUROC was 0.95 (95% CI: 0.92 - 0.97). Conclusions: This study screened out the risk factors of intussusception patients needing surgical treatment and established the appropriate prediction models.

Background: Obsessive-compulsive disorder (OCD) is one of the most prevalent anxiety-related disorders caused by many environmental factors, including anxiety. The COVID-19 outbreak has exposed nurses to greater levels of occupational anxiety. Objectives: This study aimed to investigate the frequency of obsessive-compulsive (OC) symptoms and the relationship between OC symptoms and anxiety in nurses of COVID-19 patients at Dr. Ganjavian hospital, Dezful, Iran. Methods: This cross-sectional study encompassed 190 nurses working in units for COVID-19 patients meeting the inclusion criteria. They were evaluated using a demographic characteristics form, the Maudsley Obsessional Compulsive Inventory (MOCI), and the Spielberger State-Trait Anxiety Inventory (STAI) (Spielberger, 1983). Sampling was performed via a stratified random sampling method. The collected data were analyzed using descriptive statistics (absolute frequency and percentage) and analytical statistics (Pearson correlation coefficient and independent t-test) via SPSS version 21 at a significance level of 0.05. Results: The study revealed that 74.4% of the participants showed OC symptoms, 47.4% stated anxiety below moderate, and 61.1% trait anxiety above moderate. The results of the Pearson correlation displayed that OC symptoms were significantly associated with state/trait anxiety (P = 0.001). Furthermore, the independent t-test indicated that the mean score of OC symptoms was significantly higher in females (P = 0.03) and married subjects (P = 0.006). Conclusions: The frequency of OC symptoms was high in nurses working in COVID-19 units, especially females and married subjects. There was also a significant relationship between OC symptoms and anxiety, such that anxiety increased with OC symptoms. Thus, it is suggested that nursing managers identify anxiety-causing factors in nurses to prevent more severe anxiety disorders.

Background: Implicit mental rotation has been studied in patients with schizophrenia; however, no research has examined it in relatives of the patients. Objectives: This study compared the performances of schizophrenia patients with their unaffected relatives to shed further light on the nature of cognitive functioning in schizophrenia relatives. Methods: We examined mental rotation in 25 schizophrenia patients, 25 of their first-degree relatives and 25 controls, using the Hand Rotation Task. In this task, the participants had to determine the laterality of hands showed in various orientations. Results: The results of this study revealed that the mean error rate of the relatives was significantly different between patients and healthy controls (all P < 0.03), ii), the mean response times of both patients and relatives were significantly slower than controls (all P < 0.004). Conclusions: These findings suggest that mental rotation may be a trait marker for schizophrenia.

The approaches to governance, citizen participation and social control should not only be considered complementary, but also as a sustainable trinomial to strengthen democracy within the framework of the rule of law. The events that have occurred in recentyears in political matters and in the defense of rights are symptoms of a lack of social cohesion and insufficient government effort to overcome inequality gaps, but also a warning about the impact on national security and development due to a late response to solve problems such as corruption, social conflicts and the presence of radical extreme ideas. This work considers that citizen needs converted into problems addressed through public policies must be articulated with other territorial conditioning strategies to ensure the integral well-being of citizens, as an expression of governance and full exercise of rights.

In laterite nickel exploration, PT.Vale Indonesia Tbk, initialy relied solely on drilling methods to define profile boundaries based on mineral content and rock characteristics, but discrepancies of around 2% between reserve estimates and actual mining outcomes led to the adoption of geophysical methods as a complementary approach in 2014. This study aims to determine the characteristics of laterite nickel profiles by correlating resistivity values with geochemical data. Using Datamine and Leapfrog software, a 3D model of laterite nickel profiles was generated, identifying limonite (0–10 m depth, 201–250 Ohm.m resistivity), saprolite (0–10 m depth, 101–200 Ohm.m resistivity), and bedrock (>10 m depth, 101 to >801 Ohm.m resistivity). Variations in resistivity are influenced by factors such as mineral content and morphology. The volume estimated from resistivity correlation and drillhole data is 1,625,300 m³ for limonite and 1,902,600 m³ for saprolite, compared to 1,523,100 m³ and 1,390,100 m³ based on drillhole-only data, showing discrepancies of 6% and 27%, respectively. This study provides a clearer understanding of geological modeling using drillhole and ERT data to support laterite nickel ore mining and correlation modeling.
