Meningkatkan Keterampilan Berpikir Kritis dan Hasil Belajar IPA Menggunakan Model PBL, SAVI, dan GI pada Siswa Kelas V SD
Authors: Hasanah Uswatun , Rini Tika Puspita Widya
Published: December 2024

The low levels of critical thinking skills and student learning outcomes in the science curriculum of class V at SDN Lokrawa Barito Kuala are the study's main concerns. This is because learning in the classroom is still primarily focused on the teacher, which discourages students from speaking up for what they think is right, does not offer learning exercises that encourage critical thinking, puts students in a passive role when solving problems, and results in a lack of comprehension of the subject matter. This may be the best course of action using the paradigms of group research, problem-based learning, and SAVI (Somatic, Auditory, Visual, and Intellectual). Action research in the classroom is used in this study (PTK). This class action research study aims to demonstrate the enhancements in student learning outcomes and critical thinking abilities. Exams for individual evaluation are utilized to gauge the learning objectives of students, and observation sheets are employed to gather data on the critical thinking and action abilities of both teachers and students. The study's findings demonstrated that, at meeting 4, the pupils' and teacher's traditional activity met both the very good and the extremely active requirements. At meeting 4, 93% of the students' learning objectives and critical thinking abilities were satisfied in a conventional way. These findings imply that the application of group investigation models, problem-based learning, and SAVI (Somatic, Auditory, Visual, Intellectual) might enhance students' learning outcomes in science courses as well as teachers' and students' critical thinking abilities.

Heat conduction applied in ‘River Pollutant Diffusion’
Authors: Chen Qihao , Hu Ruiqi , Wang Youwei
Published: December 2024

Environment problems are a highly valued topic in today’s society, where water pollution issue is one of the most significant that could threaten human’s safety. Sources such as industrial wastewater and agricultural runoff are affecting the water quality. Rivers around the world suffer from varying degrees of pollution. In this paper, we investigate river heat pollution and employ a numerical model to investigate its evolution and impacts downstream by adapting the heat advection-diffusion equation. We explore the stability of our numerical solutions using von Neumann stability analysis of the forward and backward differencing method of discretization of the analytical equations. We further consider a setting where there are multiple sources of pollutant in the river to explore interaction of the two pollution sources. We use python to develop the model and plot temperature diffusion in the river as a function of time and location. Our model reflects the relationship between the speed of diffusion and thermal diffusivity, and how advection enhances pollutant. Our results show that heat pollution is very quickly transported to other locations and can affect water and food quality in many locations along the river. Additionally, pollution in rivers with fast currents will be more readily transported downstream, therefore both proximity to cities and speed of river water needs to be taken into account when addressing the problem of heat pollution in rivers near cities.
Optimization Strategies for Modern Transportation and Distribution Network
Authors: Zhang Zhihan , Li Haoran
Published: December 2024

In the contemporary logistics landscape, it is a challenge to figure out the transportation and distribution problem, especially between the factory and the market. Given the increasing consumer expectation for fast delivery, the need for highly effective distribution strategies is more pressing than ever because the manufacturers and retailers have to minimize costs while maximizing efficiency. This paper aims to devise a method to optimize for costs and efficiency, and has certain reference value for how to reduce costs and improve efficiency in the freight industry. The current approach only considers the cost of products, but does not consider the cost occurring from the transportation distance. Therefore, this paper puts forward a model that considers both transportation distance and costs in optimization.

UNITARISTIČKE MANIPULACIJE NAČELOM FEDERALIZMA U BIH
Authors: Vego Milan
Published: December 2024

Strateški put Bosne i Hercegovine u vanjskoj politici je pristup NATO-u i ulazak u Europsku uniju. Imamo li tu činjenicu u vidu, onda je zaista neshvatljivo da unitarističke političke elite u bošnjačkom narodu u potpunosti ignoriraju Rezoluciju Europskog parlamenta, koja je usvojena 6. veljače 2014., a u kojoj se, između ostaloga, osuđuje svaki pokušaj unitarističkoga uređenja BiH, ali i svaki pokušaj separatizma. Dakle, centralizam i separatizam temeljan su razlog zbog čega se ruši integritet, stabilnost i funkcionalnost Bosne i Hercegovine. Rezolucija je upućena Parlamentu BiH, Vijeću ministara, parlamentima Republike Srpske i Federacije BiH, te Vladama obaju entiteta. Namjerno prešućivanje i ignoriranje Rezolucije europskih parlamentaraca, koja je usvojena sa 468 glasova dok je 80 parlamentaraca bilo protiv, a 35 suzdržano te preporuka Vijeća Europske unije o napretku Bosne i Hercegovine, pokazuje „političko sljepilo“, ali i odlučnost bošnjačkih lidera da BiH izgrade kao unitarnu centralističku državu. Zanimljivo je da bošnjačke elite iz Rezolucije uzimaju samo ono što moraju, ili što im odgovara. Uz to Europski parlament pozdravlja šest točaka Sporazuma koji je postignut u Bruxellesu 2013., i osuđuje opstruiranje centralističkih snaga i svaki oblik separatizma te naglašava načelo federalizma i legitimnog predstavljanja kako bi se osigurao nesmetan put Bosne i Hercegovine u Europsku uniju. Otuda ne čudi što je Deklaracija Hrvatskog narodnog sabora, a koja upravo počiva na Rezoluciji Europskog parlamenta i koja u ovim okolnostima teško može proći, dočekana „na nož“, uz optužbu da Hrvati ponovno razgrađuju Bosnu i Hercegovinu. Interesantno je da su se unitarističkim manipulacijama pridružili brojni mediji u Sarajevu, a čak i javni servisi veoma šturo izvješćuju o Rezoluciji.
Autor istražuje ovaj fenomen, ukazuje na njegove posljedice, analizira stavove znanstvenika o federalizmu, unitarizmu i naciji te upozorava da se sličan problem pojavio prilikom referenduma o neovisnosti Bosne i Hercegovine 1992. kada se ignoriralo referendumsko pitanje Hrvata. Ipak, i pored toga, Hrvati su masovno izašli na referendum i glasovali za neovisnu i suverenu Bosnu i Hercegovinu.

NAČINI PREVLADAVANJA KULTURNIH, JEZIČNIH I RELIGIJSKIH PODJELA U POLITIČKOM SUSTAVU ŠVICARSKE
Authors: Iličić Gordan , Bušić Mario
Published: December 2024

Švicarska je kolijevka raspršene političke moći smještene unutar jednoga političkoga sustava i stoga je tipičan primjer puke suprotnosti klasičnom westminsterskom modelu demokracije. Organizacija političke vlasti osmišljena je kao poticaj supostojanju različitih društvenih blokova s općim načelima koja počivaju na prilagođenu izboru institucionalnih mehanizama, ali i s neformalnim aranžmanima konceptualno prikladnima za heterogena i nestabilna društva. Švicarski primjer predstavlja okvir i polazište prema kojem „većina“ i „manjina“ nemaju gotovo nikakvo značenje dok je ključni mehanizam koji stabilizira politički sustav nenatjecateljska norma rješavanja sukoba unutar različitih pluraliteta. Konstrukcija političkih institucija i političkoga sustava koncipirana je tako da svi važni predstavnici društvenih skupina sudjeluju u donošenju političkih odluka, posebice na razini izvršne vlasti. Unutar tog posebnog strukturnog koncepta podjednako su zastupljeni federalizam te elementi konsocijacijske i izravne demokracije.

Published: December 2024

The proliferation of Internet of Things (IoT) devices has revolutionized various sectors by enabling real-time monitoring, data collection, and intelligent decision-making. However, the massive volume of data generated by these devices presents significant challenges for data processing and analysis. Intrusion Detection Systems (IDS) for IoT require efficient and accurate identification of malicious activities amidst vast amounts of data. Feature selection is a critical step in this process, aiming to identify the most relevant features that contribute to accurate intrusion detection, thus reducing computational complexity and improving model performance. Traditional Mutual Information-based Feature Selection (MIFS) methods face challenges when applied to IoT data due to their inherent noise, uncertainty, and imprecision. This study introduces a novel Fuzzy Mutual Information-based Feature Selection (Fuzzy-MIFS) method that integrates fuzzy logic with Gaussian membership functions to address these challenges. The proposed method enhances the robustness and effectiveness of the feature selection process, resulting in improved accuracy and efficiency of IDSs in IoT environments. Experimental results demonstrate that the Fuzzy-MIFS method consistently outperformed existing feature selection techniques across various neural network models, such as CNN, LSTM, and DBN, showcasing its superior performance in handling the complexities of IoT data. The results show that Fuzzy-MIFS increased the accuracy from 0.962 to 0.986 for CNN, from 0.96 to 0.968 for LSTM, and from 0.96 to 0.97 for DBN.

Authors: Nasrullah Nasrullah , Hamdy Muhammad Awaluddin
Published: December 2024

The objective of this research is to examine energy consumption efficiency strategies with respect to the type of dwelling unit, cooling load, and thermal comfort. This can be evaluated through the study of the hotel building air system, with the aim of ensuring the thermal comfort of its occupants. This research employs a quantitative methodology, using observation, measurement, and experimental techniques. The case study is situated within the context of hotels in Makassar City, South Sulawesi Province, Indonesia. The subject of this study is the Swissbel Hotel building, located in the coastal area of Makassar City. The data are analyzed in order to determine the Energy Consumption Intensity (IKE), Room Energy Intensity (REI), and occupancy rate based on the heat load inside and outside the building.  The data are then processed using a parametric statistical approach. Subsequently, the building envelope is analyzed through the calculation of the Overall Thermal Transfer Value (OTTV) in accordance with the standards set out in SNI 6390: 2011. The cooling load and a thermal comfort assessment, in line with the Predicted Mean Vote (PMV) index, Predicted Percentage of Dissatisfaction (PPD) index, and effective temperature according to the ASHRAE 55-2022 standard, are then calculated, and a simulation is performed to determine the most efficient strategy for the use of air conditioning energy. The findings indicated that alterations in the dimensions of the facade (sun shading) resulted in a 16% reduction in the cooling load, with the incorporation of horizontal and vertical shading sizes of 4 m × 2.5 m, square glass openings, and 8 mm heat-absorbing glass. This led to a PMV value of 0.40, a PPD of 8%, and an effective temperature value of 26.8°C. The modification resulted in a percentage gain of 20.08%, at 10-60% occupancy load with a cooling load reduction rate of 1,912,071 kW and a thermal comfort index within the comfortable range.
Accelerating Plastic Pollution Mitigation through Sustainable Urban Infrastructure Development
Authors: Salim Agus , Tumpu Miswar , Yunus Ahmad Yauri , Yusuf Andi Rumpang , Gusty Sri
Published: December 2024

Plastic waste plagues both land and aquatic environments. The surface layer refers to the road pavement layer that comes into direct contact with a vehicle's wheel surface. The surface layer distributes wheel load far more evenly than the layer underneath. The surface layer design incorporates top-notch materials that can be used as additives to enhance the quality of the asphalt mixture. This study evaluates the asphalt mixture's durability using Marshall characteristics and Cantabria tests carried out in a lab setting. An ideal asphalt concentration of 5.25% is obtained. Low Density Polyethylene (LDPE) is added to the asphalt mixture at various contents, 0%, 2%, 4%, 6%, and 8%. The study's findings indicate that adding plastic waste to the asphalt mixture can enhance its performance. The two main mitigating actions are probably plastic prohibition laws and public awareness campaigns. To evaluate the possible environmental effects and resources utilized over the course of a plastic product's life span, researchers stress the importance of its life cycle assessment and circularity. Innovations are necessary to minimize, reuse, recycle, recover, and develop environmentally friendly plastic substitutes. By empowering and educating communities and citizens on how to reduce plastic pollution and use alternative plastic solutions, governments must enforce and promote collective action. This research must prioritize addressing plastic waste as a global issue.
Analyzing Delay Factors in Iraqi Construction Projects: An ANP Approach with Najaf Governorate as a Case Study
Authors: Alklkali Ali Moosa
Published: December 2024

Construction projects in Iraq often experience delays owing to various factors, making it challenging to accurately estimate completion times. This study investigates the factors contributing to these delays, focusing on the Najaf Governorate as a case study. The primary objective of this study was to investigate issues related to the construction project completion duration, particularly considering Iraq's current unprecedented reconstruction and building efforts. The most significant factors influencing the completion duration were identified through statistical analysis of the samples and application of the Analytic Network Process (ANP) method. Data were collected and refined using a questionnaire designed according to a five-point Likert scale and administered in two rounds. The first round involved 28 participants, whereas the second round included 5 participants. The analysis revealed that contractor inefficiency, particularly from a financial perspective, is one of the most critical factors affecting construction progress and causing delays. The practice of accepting the lowest bids emerged as the second most crucial aspect leading to project delays in Iraq. Additionally, the study concluded that insufficient cash flow for the employer and the lack of technical expertise within the contractor company were the third and fourth most influential factors affecting the duration of construction projects, respectively. This study also highlighted that legal gaps in Iraq's legislative framework for construction projects are among the most significant causes of delays. Finally, the practice of subcontracting was identified as a significant contributor to both delays and poor work quality in the construction projects in Iraq.
Involving Infrastructure as a Latent Variable in Active Transportation Mode Choice: The Case Study of Baghdad City
Authors: Abdulhussein Azaldeen Ali , Jameel Abeer Khudhur
Published: December 2024

Infrastructural developments have been implemented with the objective of promoting active transportation as a sustainable transportation mode, including the construction of cycling and walking routes and the improvement of existing infrastructure. The impact of this factor on ridership has been a subject of research, and the incorporation of this variable into mode choice models has also been contemplated. Nevertheless, road users’ perception regarding the utilization of these infrastructures has yet to be investigated. Accordingly, this research aims to examine the role of infrastructure provision for walking and cycling as a Latent Variable (LV) in the transport mode choice of high school students in Baghdad City, where this subject has not been previously addressed. A self-designed questionnaire was employed to collect the requisite data. The Integrated Choice and Latent Variable (ICLV) models have been designed and the results demonstrate that the time and cost of trips have a significant impact on the choice of transportation mode. Furthermore, the provision of walking and cycling infrastructure has a notable effect on the choice of walking and cycling for transport. The sub-models indicate that the provision of cycling fences and pedestrian bridges are the most significant variables. Consequently, it is recommended that these results be considered in the provision and improvement of cycling and walking infrastructures to promote active transportation.

Published: December 2024

The latest developments in voice recognition have achieved amazing results that are on par with those of human transcribers. However, this significant efficiency may not apply to all languages, nor Arabic. Arabic is the native language of 22 countries and is spoken by approximately 400 million individuals. Verbal difficulties have become a growing problem in recent decades, especially among children, and data samples on Arabic phonetic recognition are limited. For Arabic pronunciation, Artificial Intelligence (AI) techniques show encouraging results. Some devices, such as the Servox Digital Electro-Larynx (EL), can produce voice for such individuals. This study presents a Deep Learning-based Arabic speech recognition system for automatons to recognize captured sounds from the Servox Digital EL. The proposed system employs an autoencoder using a mix of Long-Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU) models. The proposed approach has three main stages: de-noising, feature extraction, and Arabic pronunciation. The experimental findings demonstrate that the proposed model was 95.31% accurate for Arabic speech recognition. The evaluation shows that the use of GRU in both the encoding and decoding structures improves efficiency. The proposed model had a Word Error Rate (WER) of 4.69%. The test results demonstrate that the proposed model can be used to create a real-time application to recognize commonly spoken Arabic words.
Nonlinear Backstepping Control for Three-Phase Single-Stage Grid-Tied Photovoltaic Systems via an LCL-Filter
Authors: El Madani Zakariae , Yahya Abdelhafid , El Malki Zakaria
Published: December 2024

This paper examines the modeling and nonlinear control of a Three-Phase Single-Stage Grid-Tied Photovoltaic System (TPSS-GTPS). The system structure is relatively simple, comprising a Photovoltaic (PV) generator connected to the grid through a three-phase Voltage Source Inverter (VSI) and an LCL filter designed to reduce harmonics in the grid current. The primary objective of the control system is to maximize the extraction of power from the Photovoltaic Generator (PVG) and deliver it to the utility grid with a Unity Power Factor (UPF), while ensuring the asymptotic stability of the closed-loop system. In order to achieve these objectives, a novel nonlinear controller was developed in the synchronous dq-frame following the backstepping approach. Evaluating the effectiveness of the designed controller, simulations were performed in the MATLAB/Simulink environment under various scenarios to consider the effects of irradiance and temperature on the PVG. The simulation results demonstrated that the controller successfully achieved all the specified objectives. Additionally, this study highlights the effectiveness of the LCL filter in reducing Total Harmonic Distortion (THD).

Suicide is a global public health concern, with the World Health Organization (WHO) identifying it as the second leading cause of death among individuals aged from 15 to 29 years. In Malaysia, recent statistics indicate a 10% increase in suicide cases in 2023 compared to the previous year. Online forums, such as Reddit, have become platforms for sharing opinions on this matter. Extracting and automatically analyzing these discussions can provide valuable insights into public opinion concerning this issue. While the existing research primarily focuses on identifying suicidal ideation from posts, the work on discerning public opinion remains limited. This study scraped opinion posts on suicide from the Malaysian Reddit community. Sentiment Analysis (SA) was conducted using a lexicon-based sentiment analyzer and topic modeling was performed by deploying Latent Dirichlet Allocation (LDA). The analysis revealed the following insights: (1) predominantly negative sentiments were detected in the opinions, both overall and within identified topics and (2) topic modeling indicated two distinctive topics reflecting the different perspectives and concerns of the Muslim and non-Muslim communities. Specifically, the overall SA revealed that 58% of the posts were negative, 10% were neutral, and 32% were positive. Within the identified topics, the Muslim community expressed a notably higher percentage of negative sentiments at 64%, compared to the 50% found in the non-Muslim community. These findings offer evidence-based insights into public opinion regarding suicide in Malaysia, contributing to the understanding of societal perspectives on this critical issue.

The shear strength is a critical parameter in the design of Reinforced Concrete (RC) shear walls subjected to lateral loads. Numerous design codes and published studies have proposed formulas for calculating the shear strength of squat RC walls. However, there is a discrepancy between the calculated and experimental results. This study aims to evaluate various models for the calculation of the shear strength of rectangular squat RC walls using 312 databases collected from the literature. The shear strength of the RC walls was calculated using eight code- and empirical-based models, while the input parameters were obtained from the experimental database. The results were evaluated utilizing two statistical indicators: coefficient of determination and root-mean-squared error. The analysis of the results revealed that the model of C. K. Gulec and A. S. Whittaker is the optimal model, followed by the models of S. L. Wood and Eurocode-8 (EC8).

Concrete is the most widely used construction material globally. However, its production, particularly that of cement, is a significant source of carbon dioxide (CO2) emissions, contributing to approximately 8% - 10% of the global anthropogenic CO2 emissions. This study aims to analyze and compare the embodied carbon (eCO2) of various concrete strength grades commonly utilized in Indonesia to offer insights for enhancing sustainability in the construction industry. The methodology involved designing concrete mixes according to Indonesian standards and calculating carbon emissions for each component. The findings revealed that the eCO2 in the Indonesian concrete mixes was significantly higher than that reported in the UK and US databases. This higher carbon footprint emerges primarily due to the greater cement content found in the Indonesian mixes. Nevertheless, the current study demonstrated that using fly ash as a supplementary cementitious material can substantially reduce the eCO2, with the mix containing fly ash showing a 42% reduction in emissions compared to the mix without fly ash. This research emphasizes the necessity for the Indonesian construction industry to adopt sustainable practices, including optimized mix designs and the use of low-carbon materials such as fly ash. In doing so, significant reductions in the carbon footprint of concrete can be achieved, contributing to the global efforts to mitigate climate change and to promote sustainability in construction practices.

E-Government is used to provide various services to citizens via an online portal and is currently available in many countries. Current e-government technology is supported by an extensive, centrally controlled database and a collection of applications linked to it through web interfaces. However, e-government depends too much on centralization. E-government services store sensitive data about citizens, making them particularly vulnerable to cyberattacks, data breaches, and access control. Therefore, alternative techniques should be developed to protect sensitive data and ensure secure storage in e-government platforms. This study proposes a safe and distributed electronic system for e-government based on blockchain technology to protect sensitive data from breaches. This system uses advanced encryption methods, including Lightweight Encryption Device (LED) and Elliptic-Curve Cryptography (ECC), to protect transmitted data. The proposed system employs a two-layer encryption approach to secure user data. The first layer utilizes the LED algorithm with a randomly generated key, and the second employs the ECC algorithm with a public key obtained from the blockchain server to enhance user data security and privacy. The proposed system allows data to be disseminated across many networks, retrieves and synchronizes data in case of unauthorized changes, and restores them to their original form. Experimental results showed that the proposed system takes an average of 0.05 seconds to complete the login process for five successful login attempts, confirming the effectiveness of the proposed approach in the execution of login procedures. The effectiveness of this system in resisting different attack types was verified through formal and informal security analyses and simulations based on the Scyther tool.

This article presents the results of a study on the influence of 3D printing by Fused Deposition Modeling (FDM) parameters on the tensile behavior of parts made from Everfil recycled Polyethylene Terephthalate Glycol (rPETG). For this study, 27 rPETG tensile specimens with 100% recycled material were manufactured using an Anycubic 4 Max Pro 2.0 3D printer and by varying the printing parameters: height of the deposited layer in one pass, Lh, and filling percentage, Id. The Lh was set to 0.10, 0.15, and 0.20 mm and the Id was set to 50, 75, and 100 %. The two variable parameters, Id and Lh, influenced the tensile characteristics of the rPETG specimens: maximum breaking strength, percent elongation at break, and modulus of elasticity. The ultimate breaking strength and modulus of elasticity of the rPETG specimens were most influenced by Id, whereas the percentage elongation at break was mostly affected by Lh. The optimized FDM parameters for the fabrication of rPETG tensile specimens were found to be Lh = 0.20 mm and Id = 100%.
