Abstract

Banyak kota- kota besar di Indonesia yang warganya ter- infeksi sehinngga menjadi zona merah dan beberapa kota menjadi zona hitam. Berbagai cara memutus rantai penularan Covid-19 seperti mencuci tangan dengan sabun di setiap tempat, menggunakan handsinitizer, dan menggunakan masker setiap berpergian ke keluar rumah. Tujuan dari penelitian ini adalah untuk menghasilkan suatu alat penyemprot disinfektan yang ber-operasi otomatis disaat ada yang melewati sensor Ultrasonic dan bisa mengontrol per-hari yang melewati bilik ini, juga bisa memonitoring kekurangan air disinfektan pada bak menggunakan Internet of things (Iot). Pada penelitian ini membantu dalam upaya pencegahan penyebaran virus Covid-19. Bilik disinfektan ini menggunakan NodeMCU, dan sensor Ultrasonic yang akan memberikan informasi melalui website. Hasilnya dapat memonitoring jumlah warga-nya telah di sterilisasi, dan kinerja dapat memonitoring water level disinfektan-nya dengan hasil rata- rata selisih 0.37cm.

Abstract

CCTV selama ini memiliki kekurangan dalam hal penggunaan penyimpan, sementara pengawasan dilakukan penuh selama 1 × 24 jam, dan membuat kamera menulis frame terus menerus. Penyimpanan pun dengan drastis terpakai sehingga cepat penuh. Hal ini pun membuat storage seperti HDD, akan berkerja keras sehingga keawetan storage HDD tidak terjamin lama. Solusi yang bisa dilakukan adalah dengan memanfaatkan pengenalan objek sebagai kondisi. Frame hanya akan ditulis pada penyimpan ketika kamera mendeteksi adanya objek manusia. Metode Object Detection yang digunakan adalah YOLOv3, dataset dilatih dan menjadi model latih lalu diterapkan secara realtime. Model yang dilatih pada penelitian ini memiliki akurasi 100%, dan setiap objek yang terdeteksi berhasil menjadi kondisi kamera menulis frame pada penyimpan dengan ukuran video paling besar 1,6mb dengan durasi waktu 18 detik.

Abstract

ABSTRACTAsosiasi Perguruan Tinggi Informatika dan Komputer (APTIKOM) states that learning outcomes of Informatics on mathematical topics are discrete mathematics. This study aims to examine the results of students learning discrete mathematics, and examine what factors are causing students difficulty learning discrete mathematics. The method used is a mix method which is qualitative methods and quantitative methods. Data collection as the result of discrete mathematics learning outcomes, and mathematical learning difficulty questionnaire data. The population used is students of Informatics at Buana Perjuangan University Karawang with a sample of 65 students taking discrete mathematics courses in the 2018/2019 school year. The results showed that most students still had difficulty learning discrete mathematics. This is because an average value is 66,4 from the value of a test value is 55. This Test Value is the minimum passing grade. While the factors that cause discrete mathematics learning difficulties are divided into 2 classifications namely 6 influential indicators and 2 quite influential indicators. Keyword: Learning Difficulties, Learning Outcomes, Discrete Mathematics

Abstract

One important aspect in the production process is maintaining product quality and avoiding defects that could harm the company. This research aims to improve quality and avoid product defects that are detrimental to the company, especially defects in the form of bubbles in the product, by using YOLOv8. The dataset consists of 100 data which is divided into 80 for training and 20 testing data with an epoch value of 100. To obtain optimal bubble detection results, this research chose the latest version of YOLOv8 and compared several models, namely YOLOv8n, YOLOv8s, YOLOv8m, YOLOv8l, and YOLOv8x. The research results show that YOLOv8m achieves the highest accuracy among other models with a mAP value of 0.712, precision of 0.764, recall of 0.659, and F1-score of 0.708. This research highlights the potential of detection models that can detect bubbles precisely and accurately. Keywords: Kecacatan Produk, Deteksi Gelembung, Perusahaan Manufaktur, Model YOLOv8

Abstract

This research constitutes a literature review employing a qualitative approach, analyzing scholarly articles, books, and other documents related to sustainable development. This article aims to summarize and analyze previous studies concerning sustainable development in the context of mathematics education, as well as strategies that can be employed to integrate the principles of sustainable education. Integrating the principles of sustainable development into education, including mathematics education, is crucial in fostering a more environmentally responsible society and promoting sustainability across all sectors. However, its implementation remains limited. Educators face various challenges, including a lack of time, resources, and understanding of sustainable education, along with a dearth of supportive teaching materials. The principles of sustainable development can serve as a framework for developing curricula and teaching practices that are more sustainable. Educators can select mathematical problems related to environmental or social issues, discuss relevant mathematical concepts in connection with these problems, and help students comprehend the impact of mathematical decisions on the environment and society. Integrating the principles of sustainable development into mathematics education not only aids in producing a generation with sustainable skills but also motivates students to learn mathematics in more engaging and meaningful ways. A learning approach centered around sustainable development can be an effective way to prepare students for a sustainable future. The article also underscores the necessity for curriculum development, training, and professional advancement for educators.

Abstract

Jaipong dance is a traditional dance deeply rooted in the culture of West Java. However, not everyone is aware that Jaipong dance incorporates mathematical elements into its performance. Therefore, the aim of this research is to analyze mathematical concepts, particularly geometric patterns, within Jaipong dance. The research approach employed is ethnography, with data analysis including domain analysis, taxonomic analysis, and ethnographic analysis. Data was collected through three main methods: interviews, observations, and documentation. The research findings reveal the utilization of mathematical concepts in Jaipong dance. This includes counting from 1 to 8 to maintain the dance's rhythm and the use of geometric shapes in floor patterns. The floor patterns in Jaipong dance reflect the spatial arrangement used in the dance performance. Some of the floor patterns used in Jaipong dance encompass straight lines, diagonals, triangles, quadrilaterals, and pentagons. Thus, Jaipong dance not only blends artistic movements but also integrates mathematical and geometric concepts within its floor patterns. Geometry plays a significant role in creating visual aesthetics and regulating interactions among the dancers during Jaipong dance performances.

Abstract

Monkeypox is a zoonotic disease that has spread to various countries, including Indonesia. It is transmitted through direct contact with skin lesions, respiratory droplets, or contaminated objects. Early and accurate detection is crucial to reduce the risk of transmission and improve treatment effectiveness. This study aims to detect monkeypox using a Convolutional Neural Network (CNN) with the ResNet-101 architecture. The pre-processing steps include normalization and resizing of images to 224×224 pixels. The model is trained using the Adam optimizer, categorical crossentropy loss function, and an adaptive learning rate reduction. Evaluation results show that the model achieved an accuracy of 94%, with a precision of 0.92, recall of 0.92, and an F1-score of 0.92. The model is capable of classifying images effectively, although some misclassifications still occur. This system is intended to function as an initial image-based screening tool, but its results should be confirmed through clinical diagnosis and laboratory testing to ensure accuracy.
