Aim: To compare the main features of patients with secondary acute myeloid leukemias (AMLs) after post-myelodysplastic syndrome (AML-post-MDS) or post-myeloproliferative neoplasms (AML-post-MPN) and myeloid blast crisis of chronic myeloid leukemia (CML-BC) vs. de novoAMLs with myelodysplastic characteristics (dn-AML-MDS).

Materials and methods: Bone marrow/peripheral blood samples of 94 patients with secondary AMLs (30 with AML-post-MDS, 20 with AML-post-MPN, and 14 with CML-BC) and 30 with dn-AML-MDS were included. Demographic, morphological, phenotypic, cytogenetic, and survival data were analyzed.

Results: Comparative analysis showed no differences in sex and age, except for the younger age in CML-BC (p=0.005). Leukocytosis was a prevalent feature of CML-BC vs. AML-post-MPN, AML-post-MDS and dn-AML-MDS (p<0.001). At leukemia onset, thrombocytopenia was characteristic of AML-post-MDS and dn-AML-MDS whereas normal PLT counts were found in AML-post-MPN and CML-BC (p=0.001). Dysplasia in ≥2 lineages was observed in almost all dn-AML-MDS (96.8%) and AML-post-MDS (100%) compared to AML-post-MPN (33.3%) and none of the CML-BC (p=0.001). Aberrant co-expression of 1-4 lymphoid-associated markers was detected in 67.5% of all patients, including CD7, CD19, CD56, and CD22. We found chromosome aberrations in 57.8% of patients, more frequently in dn-AML-post-MDS than in AML-post-MPN, CML-BC, and AML-post-MDS. ﻿While NPM1 mutations distribution was similar in the two MDS-related AML groups, FLT3-ITD was higher in AML-post-MDS (26.3%) than in dn-AML-MDS (4.5%) (p=0.049). Regarding EVI1, CML-BC (80%) and AML-post-MPN (37.5%) showed higher incidence of gene overexpression compared to AML-post-MDS (13.3%) and dn-AML-MDS (5.0%) (p=0.001). Median time to leukemia was significantly shorter in AML-post-MDS (4.80±1.04 months) than in AML-post-MPN (20.3±2.86 months) and CML-BC (34.7±16.3 months) (p=0.008), and median overall survival was poor in all groups.

Conclusions: Similarities and differences between patients with secondary AMLs may represent different biology which translates into different clinical course and may require different therapeutic approach in future.

Predicting the weld zones size in FSSW of 304L stainless steel plates by mathematical model based on RSM
Authors: Daei-Sorkhabi Amir Hossein
Published: October 2023

The 300 series austenitic stainless steels are widely used in industries due to their special properties. High heat in fusion welding reduces the properties of these steels and causes many problems. Therefore, stir friction spot welding, which is a type of solid state welding, is useful and widely used in high-tech industries. In this paper, a 3D dynamic explicit finite element model is developed to simulate the friction stir spot welding of 304L stainless steel plates. Using this model, the temperature distribution and the size of weld zones (thickness of weld zones) are obtained. Then, by experimental study, the results of the temperature and the size of weld zones were obtained to be a criterion for comparing and validating the numerical results. Microstructure and hardness of these zones are determined experimentally. Finally, a mathematical model based on the response surface methodology is proposed to predict the size of weld zones. Good agreement between the numerical results that are produced by the finite element simulation, the proposed model and the experimental data is observed. The results show the maximum temperature level appears in the stir zone and it reduces by moving from the weld center. Also, by increasing the rotational speed, plunging depth and dwell time of the tool, the size of both the stir zone and the heat affected zone increase to a peak value and then the size of the latter zone decreases.

Published: October 2023

Battery thermal management system (BTMS) significantly improves battery electric vehicle (BEV) performance, especially under cold weather. A tradeoff between battery power consumption and cabin heating performance must be considered in cold driving conditions. This preliminary study aims to develop an integrated battery pack and coolant channel model to predict the thermal behavior of a BEV thermal management system. In this study, we develop and calibrate the physical baseline model with testbench data using finite element and CFD software. First, an electrochemical battery cell 1D model (Pseudo-2D or P2D) is built and calibrated against the cell reference data. An integrated pack model consisting of four modules (each has 23 and 25 bricks and a total of 4416 cells) with coolant flow channels is developed using reference and benchmarked data. Then, the model is calibrated against experimental results from a mass-production, mid-size battery-electric SUV operated under cold driving conditions at a constant vehicle speed of 60 km/h for 5800 sec. The integrated model considers the heat transfer characteristics from cell-to-brick and brick-to-coolant channels. As a result, a thermodynamic model that can predict the average battery temperature rise, temperature changes, and pressure drops of the coolant of the battery pack is constructed. The result shows that the battery pack model can predict the coolant pressure drop of the pack with a mean absolute percentage error (MAPE) of 0.49 % and the coolant temperature rise with a 5.23% MAPE. The calibrated battery pack model can reasonably reproduce the terminal voltage with a MAPE of 0.30%. A 3D-CFD simulation result of the battery brick model is also reported on the cell-to-cell temperature distribution of 46 cells.
Turbo Compounding of a Naturally Aspirated Single Cylinder Diesel Engine – A Simulation and Experimental Study
Authors: Ramkumar J , Krishnasamy Anand , Ramesh A
Published: October 2023

Almost one-third of the fuel energy is wasted into the atmosphere via exhaust gas from an internal combustion engine. Despite several advancements in waste heat recovery technology, single-cylinder engines in the market that are currently in production remain naturally aspirated without any waste heat recovery techniques. Turbocharging is one of the best waste heat recovery techniques. However, a standard turbocharger cannot be employed in the single-cylinder engine due to technical challenges such as pulsated flow conditions at the exhaust, phase lag in the intake and exhaust valve opening. Of late, the emphasis on reducing exhaust emissions has been a primary focus for any internal combustion engine manufacturer, with the onset of stricter emission norms. Thus, the engine designer must prioritize emission reduction without compromising engine performance. Current work focuses on enhancing the power output of a 0.6-litre, single-cylinder naturally aspirated diesel engine by employing a power turbine. Since the exhaust flow conditions were pulsated, an impulse turbine was employed. One-dimensional simulation studies were carried out after validating the base naturally aspirated engine model. An impulse turbine was designed and simulated for the pulsated flow conditions. Simulation results show that the single-cylinder naturally aspirated engine delivered a superior performance with turbo compounding. The brake power output of the turbo-compounded engine improved by 6% compared to the base NA version. Also, the thermal efficiency of the turbo-compounded engine improved by 2%. HC emissions were reduced by 31% and CO emissions by 11% for the turbo-compounded engine. Soot emissions were 2% lower, and NOx emissions were 5% lower for the turbo-compounded engine than the base naturally aspirated engine. Thus, turbo-compounding is an effective waste heat recovery system that improves the performance and reduces exhaust pollutants of a single-cylinder naturally aspirated engine.

Published: October 2023

Background: Neuromuscular disorders are rare, inherited progressive disorders leading to major disabilities over the years. As a group, there prevalence is not so uncommon and requires attention in view of their rising cases. Muscle biopsy forms an integral part of the diagnostic workup for patients with neuromuscular disorder but is performed in a very few institutes in Asia. In this study, we learn the spectrum of neuromuscular disorders presenting in a tertiary care centre of a developing country, India and evaluate the importance of open muscle biopsy. Material and Methods: 112 Muscle biopsies were reviewed and analysed for investigation of patients with suspected myopathy. Results: Of the 112 cases, 74% of the cases were adults. Mean age of presentation was 25 years and 57% of the cases were males. Pediatric cases constituted 26% of the total cases and 71% of them were male patients. Definitive diagnosis following muscle biopsy was made in 58% (n=65) of cases. Routine histological evaluation revealed the diagnosis of inflammatory myopathy 41% (n=46), muscular dystrophy in 34.8% (n=39),7.1% (n=8) neurogenic, 1.78%(n=2) mitochondrial and 0.8%(n=1) congenital myopathy of the cases. Conclusion: The burden of neuromuscular disorders has increased over the years. Molecular tests are not always helpful in diagnosing LGMD and not accessible to everyone. The role of muscle biopsy is inevitable in detecting false positive cases in mitochondrial myopathy, and for the management of Inflammatory myopathies. Awareness of the utility of muscle biopsy, expertise in diagnosing, and diagnostic challenges need more attention of the clinicians, pathologists and orientation of postgraduates to ease the journey of the patients and their families.

Published: October 2023

The ballast water used as a ship's stabilizer when it is not loaded has a negative impact on health and the environment and even causes economic losses. One of them is caused by the pathogenic microbes in it. Therefore, the International Maritime Organization (IMO) enacted the Ballast Water Management (BWM) Convention to prevent the spread of pathogenic microbes that are very dangerous to health and the environment. The purpose of this study is to find out the extent of understanding of BWM Convention of the Deck and Engine Officer Class I and II in PIP Semarang. An analytical description and an overlap approach, including questionnaires, and in-depth interviews were applied to the research method. A total of 27 students from the deck and engine departments were included in the sample. According to the survey's findings, most participants don't fully comprehend the BWM contract. When being asked whether BWM was regulated, the correct answer was 0%. The right response when being asked whether Indonesia ratified the BWM was 0%. When being asked how the efficiency of BWM was 3.7% for the D-1 standard (ballast replacement) and 11.1% for the D-2 standard (ballast handling). However, 44.4% of respondents correctly identified the significance of treating ballast water, indicating that they are worried about the threat posed by this substance and that immediate action is required. The idea is to provide the student officers with knowledge via seminars, which could include training on maritime pollution or special ballast water training.

Published: October 2023

A geophysical study was conducted to explore the shallow groundwater aquifer and to identify the subsurface structure on the basis of resistivity and geomagnetic surveys. The study area is situated in the southwestern portion of Saudi Arabia, southwest of the Najran region. The total intensity magnetic map is reduced to the northern magnetic pole. The estimated mean depths of the regional and residual magnetic sources are 3 km and 1.4 km respectively. Eighty vertical electrical soundings were measured using the Schlumberger configuration with AB/2 spacing of up to 700 m. Four geoelectrical layers were identified, and could be described from ground surface to deeper layers as the following: The first layer encompasses wadi deposits with true resistivity values ranging from 452 Ω.m to 1353 Ω.m and thicknesses of 2-4 m. The second layer is comprised of dry fine to medium grain-sized deposits with true resistivity values ranging from 104 Ω.m to 451 Ω.m, and thickness varying between 2 and 16 m. The third layer consists of water-bearing friable deposits beside the topmost part of the underlying weathered (fractured) basement. The true resistivity of this layer ranges from 22 Ω.m to 188 Ω.m, whereas the thickness of this layer is highly variable and ranges from 5 to 35 m. Generally, the resistivity values and the thickness of these three layers exhibit an increasing trend toward the main wadi stream. A fourth layer was also detected and is represented by a thin clay layer directly overlying the hard rocks of the basement complex. The dominant tectonic trends controlling the shallower parts are N-S and NNW-SSE. Meanwhile, the structural trend controlling the deeper parts is NE-SW, E-W, and. NNE-SSW. The ideal areas for drilling wells, according to the interpreted cross-sections, are along the main stream of Wadi hubuna and other small wadis, as well as the lower portions of the wadi in the extreme east direction.

Published: October 2023

Bastora basin is located 20 kilometers north-east of Erbil city. This study's objective was to determine the water equilibrium based on the climate in Erbil, northern Iraq's Bastora basin, a catchment that was of interest for potential dam building. The meteorological conditions were taken into account by the water balance method based on meteorological data collected between 1995 and 2020 at the Permam metrological site. The average annual rainfall was 597.9 millimeters, and the relative humidity was 52.56 percent. The average amount of water that evaporated each year was 1835 mm, and the average temperature was18.1 Co, wind speed was2.09 m/sec, and amount of sunshine each day were 8.2 hours. The Kharrufa method was used to find out if evapotranspiration was happening and to find out when it was deficit and surplus. The results show that there is a total potential evaporation of 1836.4 mm/year, a surplus of 301.26 mm, and a shortage of 1539.41 mm. Soil Conservation Service (SCS) is used to calculated runoff, which is 174 mm per year. The yearly recharge rate for the Bastora Basin was determined to be 3.08 x 105 m3/year, while the water surplus is 50.39 percent of the annual rainfall. Unep, Mather, and Al-Kubaisi classifications were among those utilized to determine the basin's climatic kind. According to the results of these approaches, the sequences of climatic classification in the region are found to be semi-arid, dry, and humid to moist

Mountainous regions are vital for recharging aquifers in plain areas downstream, but understanding the geological, hydrogeological, and climatic factors is crucial to comprehend groundwater processes in these regions. Several parameters, including lithology, topography, secondary porosity, geological structures, and climatic conditions, affect the potential of groundwater in mountainous aquifers. Traditional groundwater modeling tools face several challenges in handling large amounts of real-time data, such as extracting useful features, quantifying uncertainty, and identifying links between different variables. Recent technological advances in artificial intelligence, particularly machine learning, provide solutions for hydrogeological research and applications. This paper focuses on modeling potential zones of groundwater sources using various methodologies based on GIS, spatial remote sensing, and machine learning. The study evaluated three models, Random Forest, Support Vector Machine, and Logistic Regression, in identifying potential groundwater zones in the Rherhaya watershed. More than 200 localized spring points were needed to ensure efficient model learning. The Support Vector Machine model demonstrated the highest performance during the 70/30% split, with a ROC-AUC of 84.4% for the test data. The study identified four critical conditioning factors of groundwater potentiality, including Topographic position index, River Distance, Valley Depth, and Plane Curvature. The models also highlighted the distance to rivers as a significant factor, particularly in the upstream portion of the watershed. The very low potentiality class occupied the largest area (over 32%), followed by low (between 24 and 29%), moderate (12–19%), high (10–14%), and very high (only 9–12%) classes. Only the Support Vector Machine model predicted that 12% of the catchment area had high potential for groundwater resources, indicating its superior performance in identifying high-potential zones. The results offer valuable insights that can aid decision-makers in effectively managing water resources in vulnerable areas.
Tectonic Analysis of the Tall Al Qarn Pressure Ridge, Dead Sea Transform Fault, Jordan
Authors: Atallah Mohammad , Harahsheh Raw’a , Al-Taj Masdouq
Published: October 2023

Jordan's Dead Sea Transform is made up of three morphotectonic elements: Wadi Araba, Dead Sea Basin, and Jordan Valley. A few pressure ridges and depressions exist in the Jordan Valley Fault. Among these, the Tall Al Qarn pressure ridge is one of the active Dead Sea Transform's morphotectonic features. Stratigraphically, the Waqqas (Miocene), Ghor Al Katar (Early Pleistocene), and Lisan (Late Pleistocene) Formations constitute the rock outcrops in the study area. The ridge was created when the sinistral strike-slip fault of the Jordan Valley bent rightward. The major structures include the Waqqas and Ghor Al Katar inclined beds, the NW-SE oriented normal and NE-SW reverse faults and the ESE-WNW oriented dextral strike-slip faults. Faults and folds indicate a local NW-SE compressional stress caused by the sinistral Jordan Valley Fault's right bending. The steeply dipping Ghor Al Katar strata, which are overlain by the horizontal Lisan beds, display a prominent angular unconformity. Many horizontal Lisan beds exhibit abundant synsedimentary deformational features, indicating the energetic seismic activity at that time.
Geotechnical and Geophysical Investigations of Estimating Rock Mass Properties
Authors: Noori Krikar , Alshkane Younis , Rashed Kamal
Published: October 2023

Accurate assessments of the deformation and strength properties of rock masses are essential for analysing the foundations, subsurface excavation, and construction of slopes, however, identifying geotechnical properties, particularly weak rock masses, is challenging for geoscientists, geologists, and geotechnical investigators. To determine the rock mass properties, geophysical techniques, and rock mass classification methods are widely used. Although rock classification methodologies exist, they are rarely employed in foundation construction analysis due to being predominantly established for tunnelling purposes. This study aims to employ classification methods, and geophysical and geotechnical investigation approaches to provide realistic rock mass properties for a building foundation, compare results, and assess techniques' effectiveness; it also reviews current state-of-the-art methods for classification techniques and investigations. Results show that compressional and shear wave velocities increase with depth indicating a change from poor to satisfactory mechanical behaviour, and empirical equations provide highly valuable and satisfactory deformation modulus values when compared to field seismic values. Almost all classification methods provided reasonable results compared with the seismic results, however highly overestimated and underestimated outcomes were obtained from some empirical equations applying the Rock Quality Designation index and Rock Mass Rating system. Empirical equations that gave the practical deformation modulus outcomes are the Rock Mass Rating based equations and Q-based equations and Geological Strength Index-based equations. Overall, the Rock Quality Designation index underestimated the seismic result, whereas the Rock Mass Rating, Q, and Geological Strength Index systems produced good agreement and realistic results. To conclude, classification methods were effectively applied to a building foundation. Since the Rock Quality Designation is a key value and feature for other systems including Q, and Rock Mass Rating systems, it is an essential factor. Although the Q systems provided practical consequences, this system mainly relied on the Rock Quality Designation value not the compressive strength of the intact rock. The Rock Mass Rating and being the most feasible and essential systems due to detailed geotechnical observations as inputs more significantly the uniaxial compressive strength of the intact rock, and various factors including deformation modulus, strength, Poisson’s ratio, equivalent cohesion, and friction angle of rock mass as outcomes.
Evaluating Petrophysical Properties of Sa'di Reservoir in Halfaya Oil Field
Authors: Hashim Rusul , Farman Ghanim
Published: October 2023

The petrophysical characteristics of five wells drilled into the Sa'di Formation in the Halfaya oil field were evaluated using IP software to determine a reservoir and explore hydrocarbon reserve zones. The lithology was evaluated using the M-N cross-plot method. The diagram showed that the Sa'di Formation was mainly composed of calcite (represented by the limestone region) is the main mineral in the Sa′di Reservoir. Using a density-neutron cross plot to identify the lithology showed that the formation mainly consists of limestone with minor shale. Gamma-ray logs were employed to calculate the shale quantity in each well. The porosity at weak hole intervals was calculated using a sonic log and neutron-density log at the reservoir unit. Additionally, Archie's equation is applied to calculate fluid saturation using resistivity data. The reservoir water saturation in the uninvaded zone is calculated using Archie's equation, which determines the most essential element utilized in log evaluation. Finally, the permeability was measured using a flow zone indicator. The results indicate that the limestone and shale that the cuttings description report enhanced comprise most of the Sa'di reservoir. At the HF-316 and HF-21 wells, the core porosity was verified. In an uninvaded zone, the Archie equation offers the best estimation. Three equations were derived from the core data's porosity-permeability connection using a cross-plot of the reservoir quality index and normalized porosity index. According to the general interpretation, zones B1, B2, and B3 contain the most hydrocarbons; however, the B2 zone, the best layer in the Sa'di reservoir, has the highest hydrocarbon concentration. This is close to previous studies and field results. Finally, Sa'di A is formed mainly of mud lime and contains no hydrocarbons. As a result, Sa'di A was separated into A1 and A2 based on the percentage of shale difference.

Education is a vital part of any society, and it plays a critical role in shaping the future of young learners. Because traditional teaching methods are not always effective in engaging and motivating students, especially in an increasingly digital and fast-paced world, teachers should develop and implement new, innovative teaching strategies that promote and involve active learning. The STE(A)M concept is also part of the modern teaching paradigm and represents the fusion of science, technology, mathematics, engineering and art. At the same time, STEM is much more than any individual subject. It is the culture we should be building with children. At the core of this concept are active practical work, children’s engagement and exploratory learning, based on experimental or project engagement and work. STEAM is not only an introduction to science, scientific phenomena and concepts, but also children’s attitude towards creativity, challenges, solving challenges and ways of reaching (finding) solutions. In this paper, we present the essence and specifics of organizing STEAM activities with children of early ages, the importance and necessity of applying such a way of working in early childhood and the possibilities of organizing STEAM activities with children in preschools.

A healthy lifestyle, especially regular physical activity, has been shown to be a significant predictor of a childʼs health and academic success throughout the lifespan. The early years of childhood are crucial in developing a healthy lifestyle. Positive effects can be achieved with planned and organized health education in kindergartens as one of the central communities that reach most preschool children and their families. In this paper, we studied health education from the perspective of the curricula of preschool teacher education. A comparative pedagogical study was designed to investigate the characteristics of health education in the university curricula of prospective preschool teachers in Slovenia. The findings showed that students encounter health education to a greater extent during their undergraduate studies. Physical activity seems to be the most prevalent among the topics. However, future studies are needed to fully evaluate the role and potential of health education in the curricula of preschool teachers.

The aim of this paperis to determine whether significant effects can be achieved on the kinanthropological space of preschool children compared to the initial state, by applying a five-month treatment of physical exercise with dominantly applied natural forms of movement. The sample consisted of 114 boys (5.89 ± .64 decimal years) from the city of Uţice. A battery of 10 motor tests was applied: Running 20 m, Polygon behind, Tapping with hand, Bending in a sitting position, Long jump from a place, Endurance in a push-up, Raising the body, Darts, Standing on one leg on the ground and Speed of hand movement. The structure of the activity was four-part (introductory, preparatory, main and final), with clearly defined tasks. The biggest and statistically significant differences were found in the variables Running 20 m, Endurance in the push-up, Lifting the trunk and Darts. Applying an experimental program of natural forms of movement in preschool age can have the effect of qualitatively improving motor skills, but it should be borne in mind that not all motor skills are equally sensitive and susceptible to influence.

Climate change causes an increase in global temperature, which results in rising sea levels and threatens many cities in the future, including Jakarta. Carbon emissions are the primary cause of climate change, which is difficult to reduce. Forests can act as a natural filter for carbon emissions, but deforestation still occurs for various reasons. The author and their team propose a solution by creating an application called "Eden" that uses gamification to encourage users to develop a habit of planting trees. This application encourages the public to participate in saving the earth from global warming and climate change by planting trees around their homes, which can filter some of the carbon emissions in their environment.

LinkedIn is the largest professional networking application in the world, classified as a social networking site (SNS) application. Indonesia is one of the countries with the highest number of active LinkedIn users. To ensure user comfort, LinkedIn regularly updates their application. However, recently there have been some negative ratings regarding the LinkedIn application. To directly assess this, a research study was conducted to determine user satisfaction while interacting with the features available on LinkedIn. This research was carried out using the user experience questionnaire method, with 35 respondents participating. This method consists of 26 questions representing six assessment indicators, including attractiveness, efficiency, perspicuity, dependability, stimulation, and novelty. The indicator with the highest score is stimulation, with a score of 1.48, which is categorized as good. On the other hand, the lowest indicator score is perspicuity, which only obtained a score of 0.79, below average. Overall, LinkedIn has received predominantly positive feedback. However, it is still recommended to continue innovating, especially focusing on improving perspicuity aspects that are tailored to the needs and issues faced by users.

Corn is a staple food source that is rich in carbohydrates. As a source of carbohydrates, some people consume corn as daily food. Determination of corn seeds is an aspect that needs to be considered by farmers before planting because inaccurate selection of seeds can cause unsatisfactory yields and cause farmers to suffer losses. Determination of corn seeds carried out by farmers in Nansean Village and East Nansean Village is still using a manual method by looking at the size of the large fruit and choosing from seeds that have a fast harvest time but will produce unsatisfactory yields which causes farmers to feel crop failure. So it is necessary to build a decision support system that can provide answers to problems using the Simple Additive Weighting (SAW) method. The capability of the system built can provide solutions in selecting superior corn seeds for farmers and the results are in the form of rankings. The system development model used in developing this system is the waterfall model. Based on the research results, the chosen alternative in this study was alternative A01, namely NASA 29 Hybrid Corn with a total value of 0.88.

This study examines the LSTM-based model for processing spam in text data. Spam poses several dangers and risks, both for individuals and organizations. Spam can be a nuisance that hampers both individual and organizational productivity. Much spam contains fraudulent or phishing attempts to obtain sensitive information. Spam detection using deep learning involves the utilization of algorithms and deep neural network models to accurately classify messages as either spam or not spam. Typically, spam detection systems use a combination of these methods to improve the accuracy of identifying spam messages. This study applies the Bi-LSTM deep learning model to sequentially process text (sequencing). The performance of the model is determined based on the loss and accuracy. The data used are the Spam SMS and Spam Email datasets. The test results show that the Bi-LSTM model demonstrates better performance on all tested datasets. Bi-LSTM is able to capture textual patterns from both the context and the text itself, as it can combine information from both directions. The test results prove that the Bi-LSTM model is more effective in text comprehension.

In October 2022 BPOM withdrew the circulation of syrup drugs and banned the public from using syrup drugs due to the increasing cases of kidney failure in children with a mortality rate of up to 59%. The phenomenon of mass death has caused psychological trauma that threatens. The purpose of this study was to find out how public comments on Twitter and Instagram social media regarding the prohibition of using syrup drugs by classifying emotions using the Naive Bayes algorithm with Particle Swarm Optimization (PSO) feature selection. The methodology used is the AI Project Cycle which consists of problem scoping, data acquisition, data exploration, modeling and evaluation. The amount of data in this study was 1213 comments with 381 surprised comments, 318 angry comments, 277 sad comments, 137 scared comments, and 100 happy comments. Happy and afraid comments have fewer comments than other emotions, so the imbalance dataset will be handled using SMOTE. The results of this study are to compare the classification results of the application of PSO and SMOTE to the Naive Bayes algorithm to determine the best model. Based on the classification results, the Naive Bayes, PSO, and SMOTE models produced the highest accuracy values of 76.48%, with a recall value of 76.47%, a precision of 76.20%, and a fmeasure of 75.62%.
