Abstract

Indonesia is a tropical country that has various skin diseases. Tinea versicolor, ringworm, and scabies are the most common types of skin diseases suffered by the people of Indonesia. The classification of the three skin diseases can be automatically completed by artificial intelligence and deep learning technology because the classification process using an expert will require a lot of money and time. The challenge in classifying skin diseases is in the process of collecting data. Because health data cannot be obtained freely, there must be approval from the patient or hospital. Therefore, to overcome the limited amount of data, Pre-Trained CNN is used. The Pre-Trained CNN model has many patterns from thousands of images, so we do not need many images to train the model. In this study, a comparison of five pre-trained CNN models was conducted, namely VGGNet16, MobileNetV2, InceptionResNetV2, ResNet152V2, and DenseNet201. The aim is to find out which CNN model can produce the best performance in classifying skin diseases with a limited amount of image data. The test results show that the ResNet152V2 model has the best classification ability with the highest accuracy, precision, recall, and F1 score values, namely 95.84%, 0.963, 0.96, and 0.956. As for the training execution time, the ResNet152V2 model has the fastest time to achieve 95% accuracy. That's happened because the addition of the dropout parameter is 20%.

Abstract

The charity box is a supporting facility that can be used by pilgrims to distribute their infaq. In this modern era, it turns out that the mosque still counts the contents of the charity box manually and uses the usual padlock key for the safety of the charity box. The purpose of this research is to build a system and tool that can simplify the performance of mosque administrators in counting money and maintaining the security of the charity box. ArduinoBased Charity Box Safety, Tracking, and Counter System is a charity box equipped with automatic counting and security features using RFID and GPS. The method used in making this system is the waterfall method. The features in this system are automatic counting and security features using RFID keys, GPS, buzzers, and infrared sensors. This system is also equipped with a notification to the mosque management regarding the amount of money in the charity box and the location of the charity box using GSM / GPRS. From the testing of the system, it was produced that the Arduino-Based Charity Box Safety, Tracing, and Counter System was able to detect banknotes and coins well. The SMS feature also works well where there will be an SMS message regarding the amount of money and location of the charity box. The safety of the charity box is enhanced by using RFID, GPS, buzzers, and infrared sensors. From the user satisfaction test results obtained by the percentage of user satisfaction by 85%, which means the Arduino-Based Charity Box Safety, Tracing, and Counter System is quite attractive to users.

Abstract

Integrating logical and analytical thinking activities to support 21st century learning ability, into a learning activity at elementary and junior high school level becomes a challenge. One of them is less interesting learning media. One of the technologies that can be used to support exciting learning is block programming Alice and Scratch. This article aims to develop online training materials Logic and Algorithm utilize block programming scratch for level five elementary school and block programming Alice for level eight junior high school as eLearning content. The development of this research is carried out by Analysis-Design-Development-Implementation-Evaluation (ADDIE) development model. Initial products were reviewed and advised by 2 primary school teachers, 2 junior high school teachers. Product quality assessment is done based on content feasibility aspect, feasibility of presentation, language feasibility using Likert scale. The results data are then analyzed using the ideal scoring criteria to determine product quality. The results of the overall training content quality assessment show an average grade of 89.8 with good.

Abstract

Perkembangan teknologi pembelajaran berbasis multimedia menuntut para guru untuk menguasai dan menerapkannya dalam kegiatan belajar-mengajar di sekolah. Sayangnya masih banyak guru di SMP Islam Terpadu Bina Insani 1 Semarang yang belum menguasai pengetahuan dan kompetensi pembuatan bahan ajar berbasis multimedia dan ketersediaan pearlatan pendukung pembelajaran multimedia yang terbatas. Maka dari itu perlu dibuat suatu model kegiatan dalam bentuk program pelatihan dan penerapan teknologi multimedia dalam pembuatan bahan ajar para guru di sekolah tersebut. Tujuan dari kegiatan ini adalah membuat program pelatihan dan implementasi pembuatan bahan ajar berteknologi multimedia untuk memperkaya bahan ajar bagi para guru dan membantu penyediaan peralatan dan teknologi hardware dan software multimedia. Target yang diharapkan pada kegiatan ini meliputi: penguasaan teknologi multimedia pada bahan ajar lima orang guru, tersedianya tiga bahan ajar yang menggunakan teknologi multimedia. Metode yang digunakan terdiri dari empat  tahap yaitu (1) observasi kebutuhan lapangan, (2)penyediaan peralatan pendukung multimedia, (3) pelatihan SDM, (4)pembuatan materi ajar multinedia. Berdasarkan hasil kegiatan yang telah dilakukan, luaran yang dihasilkan telah melebihi target yang direncanakan meliputi : 13 guru telah mengikuti pelatihan dan menguasai teknologi pembuatan bahan ajar multimedia, telah dihasilkan 10 materi ajar berbasis multimedia, dan tersedianya peralatan penunjang teknologi multimedia seperti laptop, access point, perangkat audio. Dampak dari kegiatan ini akan memperkaya metode pembelajaran para guru dengan teknologi multimedia sehingga memudahkan siswa dalam memahami materi pelajaran.  Keywords— guru, bahan ajar, multimedia, pelatihan

Abstract

This research was carried out with the aim of developing a decision support system that is expected to be able to provide assistance and simplify the process of assessing and calculating grades and shorten the time used in awarding Pesantren Ambassadors. This system will use two decision support system methods, such as the MOORA and ARAS methods. The MOORA (Multi-Objective Optimization Based on Ratio Analysis) method uses complex mathematical calculations to solve a problem. ARAS (Additive Ratio Assessment) is an approach based on the intuitive principle that the available options should be relevant. The ARAS method has the greatest ratio to achieve the most effective solution by looking at each weight and comparing the value of each criterion for each choice. The user can determine which method he will use in determining a decision. The final result that will be displayed by the system is a battle that shows which Islamic Boarding School is selected based on the two methods.
