2D image is a form of image which has coordinates x and y, and override the factors of depth (coordinate z). In an image, there is a color information that consisting of components Red, Green, and Blue (RGB). Color information can be used as a medium for a computer program to interpret objects or values as well as the value of resistor color. By using the color information, a resistor value can be count based on bracelet color. To get good results, RGB color model need to be changed to HSI (hue, saturation, Intensity) color model first. Hue value represent the actual color, saturation level indicates the color saturation, and intensity is used to determine the number of light. By using the color selection based on HSI model and determined the value of threshold, it can be used to express the amount of resistor value in the form of a digital image.

Prediction of electrical energy crisis in Indonesia clearly will cause losses for electricity consumers. The impact caused the activities disturb include production systems, loss of business opportunities, and loss of property intellectuals (for example, data lost), especially for the scientists and academics. Customers require backup supply of electricity when PLN have some trouble. However, switching supplies electricity to Genset, if done in a conventional addition that requires the existence of the operator, but also through a complex procedure and takes a long time. Therefore need to use an automation tool that supplies electricity more practical and economical, and can be used as a medium of education, and will solve the problem of scarcity of human resources automation field, such as the electricity supply at this time. Expected performance of these tools is able to activate the genset manually or automatically in case of interruption of supply electricity, the Power Loss, Under Voltage, Lower Voltage, frequency interference. All activities since the design to the test conducted in the Laboratory of Electrical Installation and Laboratory Data Communications, Department of Educational Electrical Engineering FT UNY. The method of this experiment is a Research and Development, and experimental data taken according to the research instrument. The data obtained and analyzed using descriptive. The result that activity is the Unit of AMF Power System based on microcontroller that is ready as a medium of education, both in the Department of Educational Electrical Engineering FT UNY and Technical High School. However, this tool only can detect the interference of Under Voltage and Upper Voltage, while the interference of frequency and the condition of fuel can not be carried out due to various technical constraints.

Background: Determining severity of mitral regurgitation (MR) is very important, asit is related with prognosis and management of the disease. Currently, there is no goldstandard exists for quantification of MR severity using echocardiography. AmericanSociety of Echocardiography (ASE) guidelines recommend several parameters basedon integrative criteria using color and spectral Doppler and anatomic measurement.Left Ventricular Early Inflow Outflow Index (LVEIO Index) was proposed as one parameterto assess the severity of MR by omitting geometric error from regurgitantvolume method. Thus, LVEIO index offers a simple, easy and accurate measurementin determining severity of MR.Methods: This study was a diagnostic test research with cross-sectional design. Thesubjects were all patients with organic mitral regurgitation who underwent echocardiographyexamination to measure severity of MR using the LVEIO index as well asother parameters measurements based on parameters of ASE guidelines. Diagnostictest was used to determine the sensitivity, specificity, positive predictive value, negativepredictive value and accuracy of LVEIO index.Results: Of 49 patients in this study, 23 of them have severe MR and 26 are non-severeMR patients. The proportion of gender between two groups almost similar with an agerange from 56 to 61 years and the most common etiology finding was degenerative MR.Echocardiography examination showed the ejection fraction in severe MR was 63Â±4.2%and 64Â±3.9% in non-severe MR. The value of LAVI, MPAP, E-wave, VC, EROA andLVEIO index increased parallel with severity of MR (LAVI; 67Â±18.2 vs. 40Â±14.2 ml/m2,MPAP; 28Â±12.8 vs. 20Â±12.6 mmHg, E-wave 1.5Â±0.3 vs. 1Â±0.2 m/s, VC 0.8Â±0.3 vs.0.5Â±0.1 cm, EROA 0.4Â±0.1 vs 0,2Â±0,1cm2, LVEIO 9Â±2,4 vs. 5Â±1,8). The sensitivity,specificity, and accuracy of LVEIO index for diagnosis of severe MR were 86%, 84%,and 89%, respectively.Conclusion: LVEIO can be proposed as a relatively simple, easy and accurate methodin determining severity of MR.

One of the characteristics of Education 4.0, which is a response to the demands of Industry 4.0, is the use of adaptive and artificial intelligence technologies in online education. In relation to e-learning preparedness, many researchers have conducted studies. But in Education 4.0, the teaching and learning processes' peculiarities were not considered. Therefore, this study aims to develop and validate an instrument for assessing the e-learning readiness of students toward Education 4.0. There were 126 undergraduate students participated in this study. The respondents were asked to fill out the online-based questionnaire voluntarily. The data obtained were then statistically analyzed using the Pearson product-moment correlation test to measure the instrument's validity. The validity test showed that all items on the questionnaire are considerably valid at a significance level of 0.01. Meanwhile, the instrument reliability was measured through Cronbach's alpha score. The reliability test confirmed that six aspects out of seven of the instrument are categorized as high reliability (flexibility, learning preferences, project-based learning, data interpretation, improving curriculum, and self-directedness). One aspect (field experience) showed a moderate level of reliability. The study's findings confirmed that the questionnaire developed is valid and reliable for collecting data concerning the students' e-learning readiness toward Education 4.0.

Abstrak Salah satu dampak pandemi Covid-19 yang sangat memprihatinkan adalah degradasi moral. Maraknya kriminalitas karena krisis ekonomi ataupun keputusasaan hidup yang mendorong kepada tingginya angka bunuh diri di masa pandemi menunjukkan adanya kesalahan dalam menyikapi bencana dunia tersebut. Salah satu faktor penyebabnya adalah luputnya mereka dari petunjuk hidup yakni Al-Quran. Al-Quran yang dengan kemukjizatannya ia selalu relevan dengan zaman, seharusnya menjadi pegangan kuat selaku muslim dalam menghadapi musibah seperti pandemi. Tujuan dari penelitian ini adalah untuk mendeskripsikan kandungan ayat-ayat Al-Quran yang berkaitan dengan musibah serta menjelaskan pengamalan ayat-ayat tersebut. Adapun metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Hasil dari penelitian ini menunjukkan bahwa kandungan dari ayat-ayat tersebut setelah ditadabburi menjelaskan kepada kita sekian banyak faedah yang sangat relevan dengan kondisi di masa pandemi. Di antaranya adalah sejarah musibah penyebaran wabah tha’un, adab-adab ketika menghadapi musibah, dan kemudahan yang datang setelah musibah. Abstract One of the devastating effects of the COVID-19 pandemic is moral degradation. The prevalence of crime since economic crisis or life’s frustation that leads to high suicide rates during the pandemic indicates an error in addressing this world catastrophe. A factor is their distance from the way of live determined by Qur`an. The Quran that with its miracles is always relevant to any age, should be a strong grip as a Muslim in facing of such a pandemic. Academic problems this research try to answer is (1) How to tadabbur Quranic verses about tragedy or catasthropes? (2) How to applicate these verses in a pandemic situation? The aims of this research is to describe contents of the Quranic verses relating with catasthropes and to explain the exercise of these verses. Chosen and used method in this research is qualitative descriptive. Finding of the research shows that contents of those verses, after tadabbur, explains to us many lessons with relevances toward situation in pandemic era. In particular, catasthrope history of tha`un, ethics towards catasthropes and convenience that come after the tragedy.
