Abstract
The emergence of various web pages and social media platforms that exist in today’s digital information era makes it easy for us to access various sources of information and makes us flooded with information. This condition has the potential to result in the loss of our mental health. This is known by the World Health Organization (WHO) as an infodemic which is an excessive amount of information, both true and false, which makes it very difficult for people to find reliable news about the coronavirus, and has increased the spread of fake news, conspiracy theories, worldwide panic and confusion. WHO and all the governments of each country in the world have also carried out various efforts to break the chain of spreading fake news. But the spread of fake news around the world is faster than there is any control over it. Therefore, we need an awareness of each individual in order to equip themselves with the knowledge and skills in identifying fake news. Physics as a branch of science discipline cannot be separated from this fake news. One example of fake news about physics related to Covid-19 is the statement that the thermo gun used to measure body temperature is dangerous to human health because of its laser beam radiation. One alternative way that can be used to evaluate the truth of the news is by assessing the strength of the news argumentation. Toulmin’s argument pattern has been widely applied to analyze the quality of an argument, which can be applied in evaluating the truth of a received news content. This paper aims to provide an alternative in identifying the “infodemic” in the Covid-19 Pandemic era in evaluating the correctness of information by applying the Toulmin Argument Pattern. This argumentation pattern distinguishes three fundamental components and three additional components of a coherent argumentative discourse. The main framework of this pattern in analyzing arguments consists of three main components: claim, data, and warrant. Where data provides the basis for determining claims, warrant acts as a logical reasoning bridge that connects data and claims. Three additional components can be added to construct a more complex pattern for analyzing arguments: backings, qualifiers, and rebuttals. Where backing is the part that provides additional evidence to strengthen the warrant, Qualifiers indicate the strength provided by the warrant in relating data to claims, while rebuttals indicate circumstances where the warrant in this condition is no longer valid so that the claim can be rejected.

Abstract
On February 17, 1996, at 05:59:30 UTC there was an Mw 8.1 earthquake. Besides, it caused a tsunami. This event occurred in the northern part of the Cendrawasih Bay, where the New Guinea Thrust segment had a relatively low average slip velocity. To obtain a finite fault, waveforms from a tele-station located 30-90 degrees are used. The far-field body wave equation is used and inverted by the Kikuchi-Kanamori algorithm. In addition to obtaining source parameters, this study also aims to determine the value of the rupture velocity that occurs during coseismic events. From this research was found that the rupture velocity (vr) was 2.5 km/s, which occurred at a depth of 13.7 km. The largest value of vector slip is 2.31 m, with an average slip value of 0.922 m. The dimension area of the fault has a size of 272 km × 110 km. The seismic moment obtained is 1.5 × 1021 Nm, which is equivalent to Mw 8.1. This study also found a variance of 0.2844 in the use of the P and SH wave components, which is the smallest variance from the use of the P, P and SH, and SH components in the Kikuchi-Kanamori Program.

Abstract

Anterior Cruciate Ligament (ACL) rupture is one of the most common and severe sports injuries among the athletes caused by trauma. The standard treatment for ACL rupture patients is Reconstruction Anterior Cruciate Ligament (RACL) surgery, followed by rehabilitation lasting six to nine months. Consistent post-RACL medical rehabilitation can restore normal knee function. In this study, proposes a real-time simulation of knee joint angle estimation from electromyogram (EMG) signals for medical rehabilitation of RACL patients. Which is the continuation of this program is to be able to create an exoskeleton to increase the consistency and quality of medical rehabilitation of RACL patients. The method used to make this simulation is using LabVIEW software to simultaneous data collection between the EMG signal from the bicep femoralis muscle and the knee angle. The simultaneous data is processed using a Monte Carlo calculation to estimate the knee angle from the EMG signals. The LabVIEW simulation shows that the knee angle’s estimate was close enough to the measured knee angle and had a small time delay. It can be concluded that simulation of knee angle estimation from the EMG signal produces a good simulation and can be developed to the exoskeleton.

Published: April 2021

AbstractThe process of learning to teach face-to-face was transformed into online learning and self-assignment during the Covid-19 pandemic. Not all learning materials can be resolved by online assignments or lectures, especially learning involving scientific processes and practicum activities. Also, the analysis of various student practicum reports shows the lack of students’ ability to analyze data based on the appropriate theory. Therefore, this research aims to develop an electronic practicum module based on scientific argumentation that can be used by students as a practicum media in the Covid-19 pandemic. The type of research used is development research with ADDIE (Analyze, Design, Develop, Implement, and Evaluate) models. The developed electronic practicum module has been validated with expert judgment by five experts through validation questionnaires. Validation poll results are then changed with a five-scale score conversion based on the ideal standard deviation to determine the product validation criteria. The calculation results show that the product is in an outstanding category and ready to be tested. Furthermore, trial activities will be conducted to determine the practicality and effectivity of product intervention on the students’ scientific arguments ability.

AbstractIn the 21st century, higher-order thinking skills (HOTS) is a must-have for everyone. Teachers should train HOTS in learning physics. In the assessment of physics learning, every teacher must make a measuring instrument to measure the student’s ability in the form of physics questions. HOTS-based physics questions are needed to measure the student’s HOTS ability. Therefore, training was conducted for physics teachers in Mojokerto in August 2019 to make HOTS-based physics questions. This study aimed to analyze physics questions produced by the training participants based on HOTS-based question criteria. The method of this study used qualitative descriptive analysis. Physics questions from the results of physics teacher training analyzed one by one based on the HOTS criteria. The results show that most of the items produced had not presented contextual stimulation so that students had started to think at a higher level when reading the question stem given. Most of the problems are numerical solutions. It does not rule out that HOTS questions do not require numerical calculation but rather reasoning based on the physics concept that has been studied by students.

Published: April 2021

Abstract
The traditional sorting of fruit maturity can be done by seeing the color of the fruit’s skin. Manual sorting will take a long time and the results are subjective. This paper presents the results of maturing cantaloupe fruit based on the color of the fruit skin using a digital image of the fruit skin. The research objective is to classify the maturity of cantaloupe fruit using the Naive Bayes Classifier method and compare the results with similar studies using the Learning Vector Quantization (LVQ) Artificial Neural Network method. This study used the image of a raw and mature cantaloupe rind of 15 images each. A total of 16 images are grouped into training data for the training process and 14 other images are grouped into test data for the testing process. The results showed that the accuracy of training and testing using the Naive Bayes Classifier method was 68.75% and 57.14%, respectively. The accuracy of the training and testing of the Naive Bayes Classifier method turns out to be lower compared to the LVQ Artificial Neural Network method.

Published: April 2021

Abstract
This study used the coupled ordinary differential equations to model the phenomenon of the results of the oral glucose tolerance test (OGTT). This research has two main challenges, such as (1) implementing the OGTT model with incretin effect and (2) estimating the present model parameters. Both challenges often make calculations difficult. The OGTT equations are formed by the coupled ordinary differential equations to describe the behaviour of the glucose-insulin dynamic system in the body. While the particle swarm optimization (PSO) algorithm is used as a tool to obtain parameter estimates of the ordinary differential equations effectively. This research proves that the PSO algorithm that has been applied to calculate the parameters is a simple and efficient method for the OGTT model with the incretin effect. The PSO algorithm is proven to be accurate, its accuracy is indicated by the R
2 value. The R
2 value of all simulations proved to be above 90%.

Published: April 2021

Abstract
The accuracy of the numerical solution of the three-compartment pharmacokinetic model is generally related to the rate parameter. Therefore, in this research, the numerical solution will be applied to the pharmacokinetic model which is shaped by the nonlinear coupled ordinary differential equations. Then the particle swarm optimization (PSO) algorithm which used random numbers is used to estimate the parameters of the pharmacokinetic model. The accuracy of the estimation parameters can be predicted using the experimental data of the drug absorption concentration by using the shape suitability of the curve. Based on these study results, the PSO algorithm is very simple but provides accurate parameter estimates for predicting drug concentrations in the central compartment over the entire time span after oral drug administration. This numerical method has been tried in experimental literature data for the drug atenolol. The prediction accuracy of the drug absorption indicates that the R
2 value of all numerical results has reached above 90 %.

Abstract
Aneurysm clips have helped hundred cased for brain abnormalities including the haemorrhagic strokes over the world, including Indonesia. As one of the contributors of a hundred trillion rupiahs for medical devices imports each year, the technology of aneurysm clips is expected to be self-manufactured. However, there is no study if the process can be done in the whole country of Indonesia. This study aims to conduct a preliminary study by using an approach of reverse engineering for the Sugita aneurysm clips as an effort to independently provide domestic medical devices. The methods consist of a 3D scanning process, a 3D printing process, biomechanical simulations, and tension measurements. The clip has been scanned and printed using SS316L and Ti6Al4V. Biomechanical simulations reach 0.054 GPa for the von Misses stress and deformation number of 4.0302E-6 mm. The tension measurement on the 3D-printed clip shows identical range numbers compared to the original clip. The experiment concludes that the acquired Sugita aneurysm clip can be reversed using a 3D metal printing and shows a significant similarity on geometrical analysis.

Published: April 2021

Abstract

Objectives
Amputation due to gangrene and arthroplasty for degenerative joint disease are common orthopedic procedures and are expected to increase as populations age. Histopathologic examination of these specimens can identify unsuspected diseases.

Methods
We reviewed gangrenous amputations and large joint arthroplasty specimens for diagnosis of unexpected lymphoma, January 2014 to January 2020. Pathology and medical records were reviewed to determine diagnosis, treatment, and outcome.

Results
Five cases (0.08%) of unexpected primary extranodal marginal zone lymphoma (MZL) centered in bone were identified in 1,624 amputations for gangrene and 4,163 arthroplasty specimens. The female-to-male distribution was 3:2. Median age was 71 years (range, 62-87). The 3 cases arising in the setting of gangrene involved the first toe phalanges and metatarsals, and the femoral head was involved in all cases of joint disease (2 cases). The bone showed variable (10%-80%) infiltration by dense populations of small lymphoid cells with MZL immunophenotype. One patient died from sepsis 18.5 months after diagnosis; all others are alive with a median follow-up of 27.45 months.

Conclusions
Histopathologic examination of nonneoplastic orthopedic specimens identifies unexpected primary bone extranodal MZL in a small percentage of cases. This neoplasm may be the result of chronic antigenic stimulation in some circumstances.

Abstract
Secular trends in earlier initiation of puberty have been observed in recent decades. One risk factor appears to be increases in adiposity, as measured by body mass index. This trend is particularly notable among Latino populations, who have higher rates of overweight/obesity compared with non-Latino White youth. Previous research has focused primarily on White girls, resulting in data gaps regarding male puberty and among potentially high-risk populations. Using data from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) study, we examined body mass index at age 5 years (2005–2006) and multiple markers of pubertal onset, assessed repeatedly and longitudinally at 7 in-person visits, starting at age 9 and continuing through age 14 (2009–2015), among 336 Mexican Americans in Salinas, California. We observed no associations among boys, but found significantly earlier thelarche in overweight (HR = 1.7, 95% CI: 1.1, 2.7) and obese girls (HR = 1.5, 95% CI: 1.0, 2.4), menarche in overweight girls (HR = 1.6; CI: 1.0, 2.4), and pubarche in obese girls (HR = 1.9; CI: 1.2, 3.0), compared with normal-weight girls. This study examined an understudied population and included key covariates, such as birth weight and early adverse events, which are typically omitted in studies.
