Abstract

Candidiasis is an infectious disease caused by the fungus candida. Research on this fungus has been widely carried out until several types of candida fungi are found that can attack and cause infections in humans. Types of candidiasis also vary, but can be classified in general into three types, namely attacking the mouth (Candidiasis Thrush), vagina (Vulvoginal Candidiasis), and skin (Cutaneous Candidiasis). Candidiasis is very susceptible to infection and infection, therefore a study is needed to diagnose candidiasis. Today, expert systems are often used to diagnose diseases. There are several methods commonly used in expertise, including the Certainty Factor method and the Bayes Theorem. However, the problem faced in implementing an expert system in any field is uncertainty. This is caused by the user's hesitation in answering questions during the consultation session or even the inaccuracy of the methods used in building the system. Therefore, it is necessary to study and compare the methods that can be used to build the system. Exponential is a simple comparison that can reduce bias in the analysis process. This study aims to apply and analyze both methods and the results compare with an exponential comparison in detecting candidiasis in humans. The results of this study showed that both methods achieved the same results, namely the lowest percentage level was Candidiasis Truth, then Vuvoginal Candidiasis, and the highest was Candidiasis Cutaneous. Of these two methods, Certanty Factor is more accurate in diagnosing candidiasis.

Abstract

The automatic bell serves to signal the turn of the hour for each lesson, and there are no more picket officers who forget to ring the bell. This automatic bell will ring at the right time, so lesson changes are no longer a mess. Furthermore, the delay in changing study hours often results in the subsequent teaching and learning process being short of time in public elementary schools. As an example of the use of the Arduino Uno microcontroller which is used as an automatic school bell controller. One of the conveniences possessed by this automatic learning hour change alarm is a control system by inputting the school bell schedule into the Arduino Uno microcontroller, then the alarm for changing the learning hours for public elementary schools will activate automatically according to the adjusted school bell schedule input.

Abstract

The Pangeran Antasari Vocational High School (SMK Pangeran Antasari) Final Examination (UAS) is an activity that determines the success of a student in 2 semesters of educational activities. UAS performs better when each student's questions are displayed randomly, and the difficulty can be increased to make each student's answer different. There are 101 questions per subject in the question bank, but the system displays 40 questions for each student. The Linear Congruential Method (LCM) method randomly displays question data in the app and provides each student with a different type of question pack. Each student's UAS scores are stored in a database for subject teachers and students' academic performance. The test results for the actual student application are assigned a different set of questions for each computer the student uses. Randomization of questions for each computer used by students using the LCM method gives each student a level of difficulty, resulting in a random question package of up to 40 questions with a difficulty level of 82.5%. Because certain question numbers have the same questions, but it can be recommended to help the school in the process of UAS activities.

Abstract

The village is a very important part in determining the success of development and is in direct contact with the community, especially in public services. Digitization can be interpreted as a process of storing all the properties and information of text, sound, images or multimedia in an electronic string of zeros and ones. The village is the most accurate data source for searching population data. The Village Information System makes it easier for Villages to compile digital data and information about the objective conditions of the Village, to prepare Village Development plans based on detailed and real data. Tadukan Raga is a village in the Sinembah sub-district of Tanjung Muda Hilir, Deli Serdang Regency, North Sumatra province, Indonesia. There are 5 hamlets, namely: Hamlet I Tungkusan, Hamlet II, Hamlet III Sei Basah, Hamlet IV Lottery, Hamlet V Kampung Dalam. From the results of the development of the Tadukan Raga Village Portal Information System which has been completed, it can be concluded that the Village portal system can assist the Village in disseminating Village activities and policies, so that appeals made by the Village can be easily accepted by the community and can be well documented every activity carried out by the village.

Abstract

The bridge is a construction that is useful for continuing the path through a lower obstacle. Bridges which are part of the road are indispensable in the land transportation network system that will support development in the area. The way this tool works is to initialize the input from the photodiode sensor which detects the presence or absence of a ship. If the 1st sensor detects a ship then the light will be green then if the 2nd sensor detects a ship then the light will be red and the bridge will go up. then if the 3rd sensor is green then the bridge will go down. The result of this automatic bridge tool is that the bridge will open when the ship is detected by sensor 2 and will be closed when the ship detects the 3rd sensor. Keywords: bridge, microcontroller, photodiode, LED.

Abstract

This research focuses on the implementation of computer - based test exams in high schools which face the problem of not having differences in exam questions which results in weak security and validity of exam results. Therefore, a randomization method is needed to overcome this problem. The method used in random ization is linear congruent methods and multiplicative random number generator. There are 101 random questions, but only 40 questions are displayed for each student with a reference value of Xn and C, 2 will be added for each package of exam questions and to avoid question code=0, the calculation results will be added 1. The linear congruent methods (LCM) results achieve 100% accuracy, while the method The multiplicative random number generator (MRNG) only achieved 62.5% accuracy in randomizing the exam que stions. This accuracy comparison highlights the difference in the ability of the two methods to generate random permutations of test item packages. LCM randomization accuracy ensures that each student will receive a different set of test questions in a con sistent manner. However, the low accuracy of randomization using MRNG indicates a weakness in generating permutations of exam question packages. The results of this study show that the LCM method is better than the MRNG in conducting exams.
