Abstract

Pregnant women's health is an important aspect of the public health system, where grouping disease data can help in risk identification and better treatment planning. However, traditional clustering methods such as K-Means often face challenges in optimal separation between clusters, especially when the attributes used are irrelevant. This study aims to optimize the K-Means method in disease clustering in pregnant women by applying Random Forest-based attribute selection. Of the six available attributes (age, weight, height, gestational age, systole, and diastole), the three main attributes namely systole, diastole, and gestational age were selected based on the Importance Score from Random Forest. The test results showed that the use of these three attributes increased the Silhouette Score by 0.21 (from 0.23 to 0.44), indicating better cluster separation, and lowered the Davies-Bouldin Index by 0.69 (from 1.50 to 0.81), indicating a more compact and well-separated cluster. Clustering visualization using Principal Component Analysis (PCA) supports these results. In addition, the calculation of the Elbow method shows the optimal number of clusters at k=3, reinforcing the conclusion that the selection of the right attributes and the number of clusters improves the quality of clustering. Overall, this study proves that the selection of Random Forest-based features is able to optimize the K-Means method in disease clustering in pregnant women, which is expected to improve the effectiveness of diagnosis and treatment planning.Kesehatan ibu hamil merupakan aspek penting dalam sistem kesehatan masyarakat, di mana pengelompokan data penyakit dapat membantu dalam identifikasi risiko dan perencanaan perawatan yang lebih baik. Namun, metode clustering tradisional seperti K-Means sering kali menghadapi tantangan dalam pemisahan yang optimal antar cluster, terutama ketika atribut yang digunakan tidak relevan. Penelitian ini bertujuan untuk mengoptimalkan metode K-Means dalam clustering penyakit pada ibu hamil dengan menerapkan seleksi atribut berbasis Random Forest. Dari enam atribut yang tersedia (usia, berat badan, tinggi badan, usia kehamilan, sistole, dan diastole), tiga atribut utama yaitu sistole, diastole, dan usia kehamilan dipilih berdasarkan Importance Score dari Random Forest. Hasil pengujian menunjukkan bahwa penggunaan tiga atribut ini meningkatkan Silhouette Score sebesar 0,21 (dari 0,23 menjadi 0,44), yang mengindikasikan pemisahan cluster yang lebih baik, serta menurunkan Davies-Bouldin Index sebesar 0,69 (dari 1,50 menjadi 0,81), menunjukkan cluster yang lebih kompak dan terpisah dengan baik. Visualisasi clustering menggunakan Principal Component Analysis (PCA) mendukung hasil ini. Selain itu, perhitungan metode Elbow menunjukkan jumlah cluster optimal pada k=3, memperkuat kesimpulan bahwa pemilihan atribut dan jumlah cluster yang tepat meningkatkan kualitas clustering. Secara keseluruhan, penelitian ini membuktikan bahwa seleksi fitur berbasis Random Forest mampu mengoptimalkan metode K-Means dalam clustering penyakit pada ibu hamil, yang diharapkan dapat meningkatkan efektivitas diagnosis dan perencanaan perawatan.

Abstract

Mastering mathematical formulas is often a challenge for high school students, especially grade XI students who cover complex topics such as algebra, trigonometry, calculus, and matrices. To help students understand and apply these formulas, an Android-based application was designed that provides interactive, easily accessible, and efficient learning facilities. Technological advances allow tasks to be completed more easily and in a shorter time, but increasingly sophisticated AI can still make mistakes in language translation, for example in chatgpt, the author's concern is that if there is an error in making mathematical formulas in completing the grade XI assignment, it will mislead students if they do not pay close attention and lack knowledge in completing the assignment. This study uses a descriptive method, which aims to describe or analyze the results without making broader generalizations. Application development follows the Prototype method, a widely used software development approach that allows for continuous interaction between developers and users, ensuring a clear understanding of system requirements and functionality. The results of the study include software testing using whitebox testing, which focuses on the internal structure and implementation of the application code. At this stage, the tester has complete knowledge of the system architecture and code. In addition, black-box testing is used for functional testing, where the behavior of a system is assessed by analyzing inputs and outputs. In black-box testing, the application is run, and data is entered to verify whether the output matches the expected results. This combination of testing methods ensures the robustness and functionality of the application in supporting 11th grade students with mathematical formulas.

Abstract

In the modern era, robotic technology becomes essential for increasing efficiency and productivity in various sectors, including industry. One common robot application is the robot arm for pick-and-place tasks. This research aims to develop a robot arm with four degrees of freedom (DoF). The robot arm is designed to place glasses into packaging boxes. This research uses the principle of inverse kinematics and robot arm control software developed using Python programming language. The robot arm will be controlled using proximity sensors to read object distances or locations. The packaging process will be optimized through accurate and efficient movement planning from the conveyor to the cardboard position. Trial scenarios will be conducted to test the robot arm's ability to place glasses into packaging boxes with high accuracy. The trials were conducted 30 times within a 10-minute duration, achieving an accuracy of 99.9% for the x-y coordinates when the robotic arm picked up glasses. The accuracy of the robotic arm in placing glasses into the packaging box was 100% for the x-coordinate and 99.9% for the y-coordinate. The discrepancies in the robot's angular accuracy are attributed to inaccuracies in angle measurement, caused by uncertainties in determining the primary reference point of the stepper motor, which serves as the basis for its movement.Dalam era modernisasi, teknologi robotika menjadi esensial untuk meningkatkan efisiensi dan produktivitas di berbagai sektor, termasuk industri. Salah satu aplikasi yang umum digunakan adalah robot arm dalam tugas pick and place. Penelitian ini bertujuan untuk mengembangkan robot arm dengan empat derajat kebebasan (DoF). Robot arm ini dirancang untuk menempatkan gelas ke dalam kotak pengemas. Penelitian ini menggunakan prinsip inverse kinematics dan software pengendali robot arm yang dikembangkan menggunakan bahasa pemrograman Python. Robot arm akan dikendalikan dengan sensor proximity untuk membaca jarak atau letak objek. Proses pengemasan akan dioptimalkan melalui perencanaan gerakan pengambilan gelas dari konfeyor ke posisi kardus secaara akurat dan efisien. Skenario uji coba akan dilakukan dengan menguji kemampuan robot arm dalam menempatkan gelas ke dalam kotak pengemas dengan akurasi tinggi. Hasil uji coba dilakukan sebanyak 30 kali dalam waktu 10 menit menggunakan robot arm dalam mengambil gelas untuk koordinat x-y sebesar 99,9%. Tingkat akurasi robot arm dalam meletakkan gelas ke dalam kotak pengemas untuk koordinat x sebesar 100% sedangkan untuk koordinat y sebesar 99,9%. Perbedaan dalam keakuratan sudut robot terjadi karena ketidaktepatan dalam pengukuran sudut pada robot. Ketidaktepatan ini disebabkan oleh ketidakpastian dalam menentukan titik referensi utama dari motor stepper, yang berfungsi sebagai acuan untuk pergerakannya.

Abstract

Genetic Algorithm (GA) often requires a long computation time due to the complexity of its processes. Therefore, efforts are needed to optimize GA computation time, particularly in scheduling lectures at the Electrical Engineering Study Program of Universitas Negeri Medan, which is the focus of this research. One possible approach is determining the appropriate mutation probability (Pm) value. This study employs the Mutation Probability Variation Method, where Pm is constrained between 0 and 1 and varied from a minimum value of 0.01 (1%) to a maximum value of 0.1 (10%). Simulations were conducted using Matlab R2012b, with constant parameters including a population size of 100 and a crossover probability (Pc) of 0.85. Iterations were performed to evaluate the effect of Pm on computation time and solution performance. The results show that at Pm = 0.06, the Genetic Algorithm achieved the fastest computation time, averaging 0.382 seconds. This study also identifies that GA computation time is significantly influenced by algorithm parameters and the complexity of the problem. By selecting an appropriate Pm, a balance between exploration and exploitation can be achieved, reducing computation time without sacrificing solution quality. This research contributes significantly to the development of more efficient algorithms for optimization applications, particularly in lecture scheduling.Waktu komputasi dalam Algoritma Genetika (AG) sering kali memerlukan waktu yang lama akibat kompleksitas komputasi yang dikerjakan. Oleh karena itu, perlu dilakukan upaya untuk mengoptimalkan waktu komputasi AG, khususnya dalam perencanaan jadwal kuliah di Program Studi Teknik Elektro Universitas Negeri Medan, yang menjadi objek penelitian. Salah satu upaya yang dapat dilakukan adalah dengan menentukan nilai probabilitas mutasi (Pm) yang tepat. Penelitian ini menggunakan Metode Variasi Probabilitas Mutasi, di mana nilai Pm dibatasi antara 0 hingga 1 dan divariasikan dari nilai minimum 0,01 (1%) hingga nilai maksimum 0,1 (10%). Simulasi dilakukan menggunakan perangkat lunak Matlab R2012b, dengan parameter konstan yaitu ukuran populasi 100 dan probabilitas crossover (Pc) 0,85. Proses iterasi dilakukan untuk mengevaluasi pengaruh Pm terhadap waktu komputasi dan performa solusi. Hasil simulasi menunjukkan bahwa pada Pm = 0,06, Algoritma Genetika mencapai waktu komputasi tercepat, yaitu 0,382 detik. Penelitian ini juga mengidentifikasi bahwa waktu komputasi AG sangat dipengaruhi oleh parameter algoritma dan kompleksitas masalah yang dihadapi. Dengan pemilihan Pm yang tepat, keseimbangan antara eksplorasi dan eksploitasi dapat dicapai, sehingga waktu komputasi berkurang tanpa mengorbankan kualitas solusi. Penelitian ini memberikan kontribusi signifikan dalam pengembangan algoritma yang lebih efisien untuk aplikasi optimasi penjadwalan kuliah.
