Menurut The World Risk Index tahun 2019, Indonesia berada pada peringkat 37 dari 180 negara paling rentan bencana. Pada tanggal 5 Agustus 2018 gempa bumi di Lombok menelan korban sebanyak 259 orang meninggal dunia, dan 1.033 mengalami luka berat. Kurangnya kesiap siagaan dan edukasi mengenai bencana gempa bumi menjadi salah satu faktor penyebab banyaknya jumlah korban. Maka dari itu dibuatlah sebuah aplikasi simulasi yang ditujukan untuk mengedukasi masyarakat supaya dapat mengetahui apa saja yang harus dilakukan pada saat terjadi gempa bumi. Aplikasi ini dibuat menggunakan metode prototyping untuk melakukan identifikasi masalah yang ada pada setiap kejadian gempa bumi. Tujuan dari pembuatan aplikasi ini adalah untuk memberikan pengetahuan tentang bagaimana cara menyelamatkan diri dari gempa bumi. Aplikasi ini berbentuk game yang mempunyai sudut pandang First Person yang mempunyai empat stage dan setiap stage mempunyai beberapa misi. Pemain harus menyelesaikan seluruh misi pada setiap stage agar dapat melanjutkan ke stage selanjutnya. Hasil dari penelitian ini yaitu menghasilkan sebuah aplikasi simulasi dalam cara menyelamatkan diri dari gempa bumi. Berdasarkan uji Black-Box yang telah dilakukan, diperoleh hasil uji coba bahwa aplikasi ini dapat dijalankan dengan baik dan sesuai dengan tujuan.

Diseases on palm leaves are diseases caused by bacteria or fungi. One way to find out diseases on palm leaves is to observe the pattern on the surface of the palm leaves. The pattern on the palm leaves will be analyzed by an expert to find out whether there is disease on the palm leaves or not. This study aims to classify oil palm leaves whether there is disease or not on oil palm leaves by using a program. The right method is needed to produce good accuracy, the researcher uses the ANN (Artificial Neural Network) classification method and the LBP (Local Binary Pattern) extraction method. The steps carried out on the image before being classified are Grayscale, then extraction using LBP (Local Binary Pattern) and classification using ANN (Artificial Neural Network) using 17 train functions with the result that 5 neurons get an average accuracy of 81%, precision 95 %, and 94% recall. In 10 neurons get an average of 95% accuracy, 97% precision, and 96% recall. And the 20 neurons get an average of 97% accuracy, 97% precision, and 96% recall. Keywords: Palm leaf disease, LBP, ANN, neuron

Coffee plants are usually made for drinks made from coffee beans that have been ground into powder. One of the causes of decreased coffee quality is caused by pests that can attack from the leaves, stems and roots. This study aims to identify coffee plant diseases based on leaves using the Convolution Neural Network (CNN) method with the ResNet-50 architecture with the Adam optimizer. The total data from the dataset is 1664 images, in the dataset there are 1264 train data images and 400 test images. The highest result in training in this study using 60 epochs and Adam's optimizer with a probability value of learning_rate of 0.0001 getting a probability value of 0.9969 and the lowest value getting a probability value of 0.4918. The results of testing the test data in this study obtained an accuracy rate of 99%.

The coronavirus pandemic or known as the COVID-19 pandemic is a global pandemic of corona virus that are caused by severe acute respiratory syndrome coronavirus 2 that are started in Wuhan, China in 2019. In 30th January 2020 World Health Organization (WHO) declared an emergency situation towards COVID-19 and in 11th March 2020, WHO officially declared an ongoing global pandemic of COVID-19. COVID-19 cases in the world itself is already reaching 181 million of cases with around 3.92 million deaths. Indonesia itself is one of the country that are affected by COVID-19 spread with 2.09 million cases and 56,729 deaths. In order to decrease the amount of COVID-19 cases, WHO require each individuals to do social distancing, stay hygiene, and always wearing face mask to prevent even more spread of the virus. A method to do face mask detection is proposed using a object detection method, You Only Look Once (YOLO). The test results obtained by calculating f-measure with the highest accuracy of 0.59 and the lowest of 0.19 using CCTV video that are taken with 70 cm distance. In the second test using video that are recorded with more than 90 cm the program obtained it’s result of 0.

Weather is a brief natural event concerning the atmospheric conditions that take place on Earth which are determined by pressure, wind speed, temperature, and air phenomena. This study classifies 3 weather classes, namely sunny, cloudy, and rainy using the K-Nearest Neighbor algorithm as a weather classification algorithm with K value parameters of 3, 5, 7, and 9. Weather dataset 96.453 data to be examined is data taken from the Kaggle website. The dataset is divided into training data and test data with a ratio of 80:20. The implementation of the K-Nearest Neighbor algorithm produces a confusion matrix and classification report where in the confusion matrix, the largest number of correctly predicted data is at the value K = 9, namely 13.132 correctly predicted data with the largest number of correctly predicted data in the cloudy class, namely 10.865 data. As for the classification report, the highest accuracy value for both the cloudy, rainy, and sunny weather classes is at K = 9, which is 68.073%, and the highest precision, recall, and f1-score values are found in the cloudy class at K = 9, respectively contributed 72.095%, 89.288%, and 79.775%.

Apples are one type of fruit that has properties including preventing disease, nourishing the body and being a menu when running a diet. This study aims to develop an identification system for the maturity level of apples using the mamdani fuzzy logic method. Fuzzy logic mamdani is a fairly good method of identification because the classes to be used have been predetermined. In this study, the apples used were Rome Beauty apples. The maturity level is based on the color which is divided into two, namely green raw and reddish yellow ripe. Data processing is done by preprocessing images such as resizing fruit directly. The accuracy of the dataset measured using this method results in an accuracy of 96%. In this study, an analysis of the input and output features needed by Mamdani's fuzzy logic was also carried out in classifying the maturity level of apples. The results showed that the input data could not be used effectively to classify the maturity level of apples due to the lack of input types used.

Abstract: Effective information management and improved access to educational programs remain key challenges for non-formal educational institutions such as PKBM Sekolah Bintang. To address these issues, this community service activity was designed to enhance the digital skills of PKBM administrators through training in the creation and management of a CMS-based WordPress website. The training was conducted in an interactive and practical manner, with PKBM students as the main participants. Evaluation results indicated a significant improvement in participants’ ability to independently manage the website, from installation and design customization to digital content management. The website now serves as an effective communication and promotional tool to broaden the reach of the institution’s educational programs. However, continued training and technical support are still needed to optimize website management and ensure the sustainability of the institution’s digital capacity. Overall, this initiative contributes significantly to strengthening the use of information technology in non-formal education. Abstrak: Pengelolaan informasi yang efektif serta peningkatan akses terhadap program pendidikan menjadi tantangan utama bagi lembaga pendidikan non-formal seperti PKBM Sekolah Bintang. Untuk mengatasi hal ini, kegiatan pengabdian masyarakat ini dirancang guna meningkatkan kemampuan digital siswa PKBM melalui pelatihan pembuatan dan pengelolaan website berbasis CMS WordPress. Pelatihan yang berlangsung secara interaktif dan praktis melibatkan murid PKBM sebagai peserta utama. Evaluasi hasil pelatihan menunjukkan adanya peningkatan kemampuan peserta dalam mengelola website secara mandiri, mulai dari instalasi, pengaturan tampilan, hingga pengelolaan konten digital. Saat ini, website tersebut berfungsi sebagai media komunikasi dan promosi yang efektif untuk memperluas jangkauan informasi program pendidikan kesetaraan. Meski demikian, pelatihan lanjutan serta pendampingan teknis tetap diperlukan guna mengoptimalkan pengelolaan website dan mendukung keberlanjutan peningkatan kapasitas digital lembaga. Secara keseluruhan, kegiatan ini memberikan kontribusi penting dalam memperkuat pemanfaatan teknologi informasi pada pendidikan non-formal.
