Cognitive Load Theory on Virtual Mathematics Laboratory: Systematic Literature Review
Authors: Hery Murtianto Yanuar , Agus Herlambang Bambang , . Muhtarom
Published: December 2022

The primary goal of cognitive load theory is to improve the learning of complex cognitive tasks by transforming current scientific knowledge on how cognitive structures and processes are organized into guidelines for instructional design. Cognitive load theory assumes that the bottleneck for acquiring new secondary biological knowledge is the limited working memory capacity. In the ideal situation, the working memory resources required for learning do not exceed the available resources. Despite this, in reality, there will often be a high cognitive load, or even ”overload,” for two reasons. First, dealing with interactive information elements in complex cognition imposes a high intrinsic working memory load. Second, learners also have to use working memory resources for activities that are extraneous to performing and learning tasks, that is, activities that are not productive for learning. Virtual Laboratory is a form of animation that can visualize abstract phenomena or complex experiments in natural laboratories to increase learning activities and develop problem-solving skills. A virtual math laboratory was created to optimize dual coding memory, namely verbal and audio learning. The investigation tracked the approved reporting Items for Systematics Reviews and Meta-Analysis (PRISMA) guidelines, illustrating the outcomes of the literature searches and articles selection process. It is used to provide that the selection process is replicable and transparent. We accomplished a computerized bibliometric analysis from 2002-2022 for articles retrieved from the SCOPUS database. Data were collected in July 2022.

Published: December 2022

Indonesia’s geographical condition is vulnerable to geological changes and prone to natural disasters. The Indonesian Government has made various efforts to reduce disaster risk by developing disaster-safe education units. Disaster education will be effective if it is integrated into the curriculum in the school subjects such as social studies from an early age. This study aims to provide ideas for implementing disaster mitigation learning for high school students based on the concept of Merdeka belajar in the digital age. To better understand disaster preparedness under the concepts of Merdeka belajar, we thoroughly examined the relevant databases. It was carried out within the education framework put out by Ki Hadjar Dewantara (1889–1959), Johann Friedrich Herbart (1776–1841), and Jan Komensky (1592-1670). Given that Indonesia has at least 13 disaster threats whose risks vary depending on the region, it is crucial to understand the local wisdom in disaster mitigation. This content is available in high school phases’ natural and social sciences subjects (ilmu pengetahuan alam dan sosial, IPAS). This research is crucial to successfully improve the teaching-learning quality to meet the needs of the Pancasila student profile.

Authors: Dwijayanti Ida , Andri Nugroho Aryo , Esti Utami Rizky
Published: December 2022

This study aimed to determine the effect of learning tools based on the analysis of students’ conceptual errors on TPACK abilities. This study uses an experimental method involving 105 samples in extracting the initial TPACK data owned by students studying to be teachers and their teachers. In the final data collection, 2 students carried out learning using a device that had been designed based on the possibility of student errors in the trial class, and 2 teachers taught conventionally in the control class. The data was taken by observing the TPACK indicator’s achievement for students and teachers. The study results show that the content knowledge capabilities of prospective teachers have a better opportunity to present more actual problems and provide opportunities for students to develop higher-order thinking skills. In this case, the students introduced the concept of algebra (variables, coefficients, constants and real number operations) in the problem of managing pocket money, while the teacher gave the problem of the number of balls in a cardboard box. The implication is that the readiness of prospective teachers to teach will be better.

The Practice of Classroom Assessments during Curriculum Change: A Study of Inservice Teachers
Authors: . Wiyaka
Published: December 2022

The education ministry has refreshed the past school curriculum to the Freedom Curriculum or Kurikulum Merdeka. Ideally, the change of curriculum is alignment with the methods of assessment. In terms of assessments, there are three types highlighted in the new curriculum: diagnostic, formative, and summative assessments. The question arises whether the teachers can really cope with the current issues in assessment. This research aimed to survey the teachers’ perceived skills in assessment and to examine the practices of classroom assessments dealing with the latest issues, including the assessment they used most. A questionnaire was used to collect the data. The respondents were 276 teachers from various backgrounds. They were in-service teachers who joined the Teacher Certification Program managed by Universitas PGRI Semarang in the year 2022. Descriptive statistics was used to calculate the data. The results revealed that teachers reported being fairly skilled in doing assessments. However, several subskills in assessment need improvement. Among the three types of assessment, summative was mostly practised by teachers while teachers least frequently conducted the diagnostic. Based on the function, assessment of learning was mostly practised by teachers, while assessment as learning was the least frequently used. The in-service teacher training program curriculum must cover course materials in assessment to better equip teachers with the ability to execute various assessments.

Estimation of Hourly Solar Radiations on Horizontal Surface from Daily Average Solar Radiations Using Artificial Neural Network
Authors: Kurniawan Adi , Shintaku Eiji
Published: December 2022

Hourly solar radiation information is necessary to increase the effectiveness of photovoltaic (PV) energy systems. However, compared with daily average solar radiation, the measurement of hourly solar radiation is much less available. In this study, a multilayer perceptron artificial neural network based on daily average solar radiation is proposed to estimate the amount of hourly solar radiation. The proposed method also relies on the location of the PV system, the hour when the estimate is needed, and the month when the estimate is needed. Two separate networks were built to estimate hourly direct solar radiation and hourly diffuse solar radiation, the summation of which is the estimated value of global hourly solar radiation. The networks were trained using three years of data from 2016 to 2018 from five locations around Japan. The data were taken from the website of the Japan Meteorological Agency (JMA). The number of hidden neurons for each network was determined by comparing the regression value obtained during the training process. The proposed method was validated by comparing the estimated value with the actual measured solar radiation value for each month in 2019 for the same five locations used for training the networks. The reliability of the proposed method was confirmed with the minimum R2 of 0.951 for the estimation of hourly direct solar radiation and 0.983 for hourly diffuse solar radiation. Further improvement in the accuracy of estimating the daily peak radiation value is considered to improve the total accuracy of the estimation model in the future.
Evaluation of Average Term Occurrences Weighting Technique for Arabic Textual Information Retrieval
Authors: Abuata Belal Mustafa , Al Omari Lama Ali
Published: December 2022

Information retrieval of documents is an important process in the current time, and the vector space retrieval model uses a term weighting scheme as a basic method for matching queries with documents. Term frequency-Inverse document frequency is a widely used and famous term weighting scheme, and many studies proved its effectiveness in information retrieval. However, this term weighting scheme has some drawbacks like retrieving irrelevant documents, which sometimes reduces effectiveness. From this point, a new term weighting scheme called Term Frequency with Average Term Occurrence was proposed and experienced in the English language to minimize retrieving unnecessary documents. In this paper, an information retrieval system is built for the Arabic language, and Open-Source Arabic Corpora was used to complete experiments. Calculations were made using two schemes which are traditional Term frequency-inverse Document Frequency and proposed Term Frequency with Average Term Occurrence. After that, comparisons of results were made using evaluation measures. With all obtained queries, four case studies with two approaches (stop word removal and stemming) are implemented. In English experiments, stop word removal was applied with another discriminative approach, which calculates the centroid of documents. After the analysis of the results, it was found that the proposed scheme is applicable on Arabic text and applied approaches enhance IR effectiveness if they are both implemented. Furthermore, it was found that stop word removal has a favorable effect on both schemes which was also proved in English experiments.
Estimating Indonesian Complete Life Table and Fair Annual Pure Premium Range from Abridged Life Table with Bayesian Method and Bootstrapping
Authors: Chandra Christian Evan , Abdullah Sarini , Devila Sindy
Published: December 2022

Several Indonesian life insurance companies recently faced financial problems due to inadequate pricing and idealistic investment expectation. Growing market and insurtech implementation might lead to worse conditions in the future. The current mortality table and investment return assumption are too ideal, so more conservative assumptions are required to get a more reasonable annual pure premium range. This research estimated complete life tables from abridged life tables by truncated Heligman-Pollard and Makeham model, when a lognormal stochastic process estimated annual investment return. Parameters for mortality models and return distribution are estimated using Bayesian method with Metropolis-Hastingâ€™s algorithm. Data from the abridged life table was bootstrapped due to insufficient number for statistical parametric modeling. Good accuracy for estimated abridged mortality rates was reached by referring to the Mean Absolute Percentage Error (MAPE) metric for both males and females, also for the young ages group (new-born to twenty-nine years old) and old ages group (thirty to eighty-four years old). The parameters were satisfactory to estimate the complete life table and extrapolate annual mortality rates calculation until age ninety-nine. A log-normal distribution was found to fit the monthly inflation rates satisfactorily. Assuming that investment return is close to the inflation rates, the annual investment return is anticipated for both profitable and losing situations. Therefore, insurance companies can win the customersâ€™ decisions without compromising their financial stability.

Published: December 2022

This research was conducted on the Surakarta-Gemolong-Geyer road, which is suspected to be built on expansive land. Every day, this road is always passed by large vehicles, so it is feared that it will be easily damaged if it is not routinely carried out maintenance. This study aims to analyze the damage to the rigid pavement on the highway using ATENA 3D software. The damage analyzed in this study is the deflection. The factors that make the crack large and wide were added to the heavy vehicle load and swelling. The swelling test on the soil carried out in the laboratory was 37 kPa. The results obtained after analysis with 3D ATENA showed differences in deflection at each loading variation. The variation of the middle loading with swelling pressure has a value of -15.49 mm; without swelling pressure, it is -16.37 mm. The middle loading variation with swelling and without pressure has a value of -15.33 mm and -12.4 mm, respectively. Corner loading variation with swelling and without pressure has a maximum deflection of 1.28 mm and -0.26 mm, respectively. This research can be used as a reference and prediction in identifying cracks that occur so that the government can carry out maintenance and rehabilitation before the road is damaged.

Authors: Sophian Alfi , Abinawanto - , Dwiranti Astari , Ulfah Maria
Published: December 2022

â€” This study aims to obtain data on the diversity of nisi chickens based on morphometric analysis of body weight bioacoustic analysis of the crowing sound. The number of studies that link morphometric analysis with bioacoustic analysis is one of the reference sources used as a reference in conducting this study. In the future, it is hoped that this research will be one of the contributions of knowledge for further research or similar research. The parameters used in the analysis are neck length for morphometric analysis and bioacoustic parameters using the number of crowing syllables, crowing duration, and wave frequency. The data generated from the morphometric analysis were then analyzed statistically for the average test using ANOVA which was analyzed together with the data generated from the Cold Edit Pro software to conclude the resulting data. The parameters observed were the number of crowed syllables, crowing duration, wave frequency, and crowing frequency. The results showed that the duration of the crowing of the nisi chicken ranged from 1.922 seconds to -2.064 seconds with an average duration of 1.9837 seconds. The results of morphometric analysis of neck length obtained that the average neck length of 30 chicken samples was 10.25 cm with the shortest range being 10.0 cm and the longest being 10.8 cm. The results of sound analysis for the wavelength frequency of the crowing of the nisi chicken ranged from 698.10 Hz - 786.22 Hz with an average wavelength of 733.89 Hz. For the number of syllables produced from the crowing sound, uniform results are obtained in the form of 7 syllables. The results of the analysis using ANOVA obtained an F count of 0.001447 smaller than F table 1.656383. The conclusion in this study is that the neck length morphometric analysis does not affect the bioacoustic analysis so that the diversity of nisi chickens analyzed shows uniformity.
A Fog Computing Framework in IoT Healthcare Environment: Towards A New Method Based on Tasks Significance
Authors: Shanshool Abeer Mohammed , F. Abbas Noor Alhuda
Published: December 2022

The Internet-of-Things (IoT) is an important technology and is considered the future of the Internet. Healthcare is described as one of the important areas in IoT used for remote patient monitoring. Real-time remote monitoring health applications are important as delays in data transfer between the cloud, and the application may be unacceptable. Fog computing refers to a geographically distributed computing system with several devices connected to the same network to achieve flexible and collaborative computation, storage, and communication services. Fog computing is mainly used for efficient data processing between sensors and cloud computing as it reduces the volume of data exchanged between sensors and the cloud, thereby improving the whole systemâ€™s efficiency. Wireless sensor networks (WSN) are also used in health monitoring systems to simultaneously transfer huge data volumes (of different priority levels and length values) to the fog computing system. Hence, there is a need to appropriately implement a task scheduling mechanism that can accurately prioritize tasks irrespective of their length. This study aims to systematically review the existing fog computing technologies in the Internet of things HealthCare (IoTH) systems and improve the performance of the available static task scheduling algorithms using the Tasks Classification (TC) method where task importance is paramount. The performance of the suggested approach was evaluated based on the Max-Min scheduling algorithm (SA).
Organizational Resistance to Technology Diffusion: The Case of IPv6
Authors: Syamsuar Dedy , Dell Peter , Witarsyah Deden , Luthfi Ahmad
Published: December 2022

IP address is an essential protocol to identify every connected device to the Internet uniquely. IPv6 was developed as a long-term solution to overcome IPv4's shortcomings. However, IPv6 adoption is still very rare. Organizations tend to resistance to adopting and implementing IPv6 on their network. This study aims to develop and test a model of organizational resistance to IPv6, an Internet Protocol (IP) intended to replace IPv4, the widely used incumbent. This exploratory mixed-methods study analyzed interview data from Indonesian organizations, supplemented with insights from prior literature, to identify factors of organizational resistance to IPv6. A subsequent survey of Indonesian organizations was conducted to assess the relationship of each factor with IPv6 resistance. The survey data was then rigorously analyzed using PLS-SEM. While IPv6 is typically portrayed as an essential Internet infrastructure development, Indonesian organizations perceive it as unnecessary and threatening. A Structural Equation Model of IPv6 Resistance was developed and posits that although perceived threat, perceived lack of need, and environmental influences all influence organizational resistance to IPv6, switching costs and satisfaction with current technology have no impact. This study has practical implications for organizations that aim to promote IPv6 diffusion; promotion strategies should address the key factors identified in this study. While prior models of technology resistance have focused on individual-level resistance to technologies promoted from within the organization, this study focuses on organizational-level resistance to technology promoted by sources external to the organization and hence makes a new theoretical contribution.

The data instrument uses a questionnaire as a research instrument that assesses the indicators of each variable which is an elaboration of factors from the stages of City-park's construction project management, community involvement, and the quality of city parks. The results showed that the city park's management system was still far from expectations, and weaknesses were found in managing the pre-construction stage and stakeholder involvement, which was not carried out optimally. It causes the construction phase not to be adequately monitored, and the project results are of poor quality. Based on the study results, further research is needed to examine the pre-construction stage and stakeholder involvement more deeply so that quality city parks according to the expectations of Jakarta residents can be achieved.

The Traveling Salesman Problem (TSP) is very popular in combinatoric optimization. The TSP problem is finding the optimal route from several cities where the distance between cities is known, and a salesman must visit each city exactly once and return to the origin city. The goal is to find a route with a minimum total distance. This problem is known as a non-deterministic polynomial hard (NP-hard) problem, which means the computation time to find a solution increases exponentially with the size of the problem. NP-Hard problems can be solved by using heuristic methods where the solution obtained is good enough (does not guarantee the most optimal solution) in a reasonable time. One of the most recent variants of TSP problem is finding the cheapest flight routes to several cities, which is part of the Traveling Salesman Challenge 2.0 (TSC 2.0) 2018 competition . This paper reports our study of implementing an artificial bee colony (ABC) algorithm for the TSC 2.0 problem. ABC algorithm is chosen based on its superiority over other algorithms in several optimization problems. The algorithm is implemented in a hyper-heuristic form. Several combinations of swap operators are used to find the best combination result. The experimental result shows that the ABC algorithm can solve the TSC 2.0 problem with a fairly good performance by producing a savings cost of 54.6% from the initial solution and 26% compared to the Genetic Algorithm.

This research was established at El Prado-IASA1 farm, Agricultural Engineering Career, on a soil of volcanic origin of the Andisol order, in order to evaluate the quality of the forage due to the effect of chemical fertilization and four amendments: lime (E1), gypsum (E2), magnesium silicate (E3) and phosphate rock (E4), mixed amendment (EM) and two level of NPK fertilization. These treatments were applied in an established meadow with: kikuyo (Pennisetum clandestinum), blue grass (Dactylis glomerata), perennial rye grass (Lolium perenne) and white clover (Trifolium repens). The amendments and fertilization were incorporated after the first cut, in an amount equivalent to 1500 of lime, 500 of gypsum, 300 of magnesium silicate and 300 of phosphate rock kg ha-1 year-1, plus fertilization F1: N100-P50-K50 and F2: N300-P100-K100, fractionated for 10 cuts per year. The variables evaluated were: green mass production, dry matter, macro and micronutrient soil content. The forage assessment was based on the physiological growth of rye grass as a dominant prairie species. The results positively affected the quality and production of forage in t ha-1, due to the effect of lime, phosphate rock, and NPK fertilization. There was a high fixation of NH4, K, and P, due to the effect of amorphous minerals, high Fe content, and water deficit. Hence it is recommended to keep close to the soil's field capacity level.

Hospital outpatient waiting times in Indonesia do not meet the standards. Lean management reduces waste, while digitalization plays a role in managing service complexity. Implementing lean in parallel with digitalization increases the opportunities for improvements, but empirical research on this is still limited. This study aimed to generate an analytical study of the impact of Lean application in reducing the waste of waiting time for outpatient services at a government hospital. The research design was pre- and post-intervention. The study was conducted in a regional government hospital with 80 people as a sample who was recruited by systematic random sampling. Data collection was carried out through observation and mapping the flow of patient service time from booking to completion of a doctor's consultation using the time stamp. Efforts to reduce waiting time are carried out through a simulation of the Lean-based digitalization model. The variables are the number of Service Steps, Lead Time, Waiting Time, Value-Added Activities, Non-Value-Added Activities and Value-Added Ratio (VAR). The results showed that lean-based service digitalization was able to reduce service steps from 10 to 4 steps, waste waiting from 5 to 2 steps, and Lead Time from 336 to 39 minutes (-88.4%), increasing the VAR from 5.1% to 20.5%. This research is limited to the implementation of lean digitally. It is important to statistically compare the impact of digital and non-digital lean implementation in some hospitals.
A Comprehensive Review of DNS-based Distributed Reflection Denial of Service (DRDoS) Attacks: State-of-the-Art

Published: December 2022

Cyberattacks significantly impact the services based on the internet that is used in our daily lives. Any disruption will make it extremely difficult for us to carry out our daily activities. Cyberattacks will disrupt online services, exploit vulnerabilities to breach databases and servers, and so on. Various systems and services contribute to the Internetâ€™s seamless functionality. The Domain Name System (DNS) is one of the most important services. DNS is used to resolve domain names into machine-readable IP addresses. DNS, like many other Internet services, is vulnerable to cyber-attacks. While DNS faces a slew of threats, one in particular appears to stand out. DNS is vulnerable to a variety of distributed denial-of-service attacks. The distributed reflection denial of service (DRDoS) attack, a flooding attack against DNS servers that renders them unavailable, disrupting domain name resolution activities, is one of the most common variants. DRDoS attacks have been on the rise in recent years. DNS lookup outages would significantly impact our online activities in the world of ultra-connectivity because they are typically the first step in establishing a connection with a server. The purpose of this paper is to present a state-of-the-art review of DRDoS attack detection and mitigation algorithms as well as the datasets on which these algorithms operate. Finally, we discussed each of these algorithms' relative merits and demerits.
