Abstract

Stunting is a disorder that attacks the growth and development of children and babies caused by chronic malnutrition which is characterized by a body length or height that is below standard. Many factors underlie the high incidence of stunting, one of which is improper Infant and Child Feeding. The growth and development of toddlers is closely related to food intake which can have a major influence on optimizing the development and growth of infants and toddlers in 1000 HPK. The Kampung KB Membangun Desa is located in the Rasau Jaya Umum Village, Kubu Raya Regency, which is the focus of accelerating stunting reduction. The stunting rate in the district reached 27.8% in 2022. The stages of community service activities begin with coordination of activities with the coordinator, then continued with counseling and training. Community service is carried out using lecture, demonstration and question and answer methods supported by PMBA module media and equipment. Evaluation of counseling activities is carried out by providing a questionnaire sheet containing 10 questions. From the results of the SPSS analysis test, the respondents knowledge during the pre-test was 66.67%. After being educated, there was an increase in respondents knowledge during the post-test of 83.3%.

Abstract

Attendance is the process of recording attendance as a form of employee discipline and professionalism. Manual attendance is very time-consuming and errors often occur in making attendance recaps because you have to count attendance one by one and attendance data can still be manipulated. Therefore, designing attendance using RFID and fingerprints can help to improve employee discipline and make the attendance process easier. Apart from that, attendance using RFID and fingerprints has advantages compared to manual attendance, such as making the attendance process easier, recording and storing attendance data in a database. Fingerprints also have quite high security because human fingers have unique fingerprints. By using the NodeMCU ESP8266 as a microcontroller that can connect to the internet, the attendance process is only done by scanning the attendance tool, and then processing the data using the website, which will produce more accurate attendance information compared to manual attendance.Keywords: Attendance; RFID; Fingerprint; NodeMCU ESP8266 microcontroller.    AbstrakPresensi merupakan proses pencatatan kehadiran sebagai bentuk kedisiplinan dan profesionalisme karyawan. Presensi manual sangat menyita waktu dan sering terjadinya kesalahan dalam melakukan pembuatan rekap presensi dikarenakan harus menghitung presensi satu per satu dan data presensi masih dapat dimanipulasi. Oleh karena itu, perancangan presensi menggunakan RFID dan fingerprint ini dapat membantu untuk meningkatkan kedisiplinan karyawan dan mempermudah dalam proses presensi, selain itu presensi menggunakan RFID dan fingerprint memiliki kelebihan dibandingkan presensi manual seperti dapat mempermudah proses presensi, perekapan serta data presensi tersimpan didalam database. Fingerprint atau sidik jari juga memiliki keamanan yang cukup tinggi dikarenakan jari manusia memiliki sidik jari yang unik. Dengan menggunakan NodeMCU ESP8266 sebagai mikrokontroler yang dapat terhubung ke internet proses presensi hanya dengan scanning pada alat presensi, kemudian dilakukan pengolahan data dengan website maka akan menghasilkan informasi kehadiran yang lebih akurat dibandingkan dengan presensi manual.

Abstract

Pemenuhan SDG"™s di Indonesia salah satunya ditunjang oleh sektor pertanian. Produk pertanian dengan yang menjadi perhatian adalah padi. Pertumbuhan padi di Indonesia dapat tumbuh dengan subur karena di dalam tanah memiliki kandungan unsur hara. Kandungan unsur hara penting yang dibutuhkan oleh padi agar tumbuh dengan cepat adalah nitrogen, phosporus dan kalium / potassium (NPK). Kandungan unsur NPK yang terkandung di pupuk atau tanah melalui analisis laboratorium dengan biaya yang relatif mahal dan waktu yang lama. Untuk itu perlu cara lain yakni menggunakan soil integrated sensor. Penelitian ini memiliki tujuan untuk mendapatkan informasi terkait kandungan unsur hara pada lahan pertanian padi menggunakan soil integrated sensor serta lokasi menggunakan sistem informasi geografis. Parameter yang digunakan antara lain suhu tanah, kelembapan tanah, electrical conductivity, pH tanah, nitrogen, phosporus, potassium dan salinitas tanah.

Abstract

Diagnosing liver disease in the field of healthcare is not an easy task. However, by utilizing medical records as datasets and applying data mining methods such as K-Nearest Neighbor (K-NN), we can analyze and extract knowledge automatically. The K-NN method has proven to be more effective compared to other methods as it clusters new information by selecting the nearest neighbors based on the value of k. In this study, we employed the Elbow method to determine the optimal value of k by measuring the error rate. The test results revealed that the optimal value of k was found to be 4, with the lowest error rate. In the third test, we achieved a training accuracy of 80.5% and a testing accuracy of 78.9%. After fine-tuning the training data, we were able to improve the accuracy to 82.2% for training and 77.1% for testing. However, in the fourth test, we encountered overfitting issues due to data imbalance caused by inappropriate resampling, resulting in a model that was overly complex and prone to excessive noise.

Abstract

Identifying hand gestures in semaphore code accurately and in real time is a challenge. Especially for Scouts who are just learning this skill to minimize errors that can result in inappropriate information received and can affect the safety and effectiveness of communication. The use of Decision Tree in identifying hand gestures can make a significant contribution for Scouts to communicate more effectively. Based on the test results, this model can recognize letter classes in semaphore ciphers with normal lighting as evidenced by a higher accuracy rate. The average accuracy in normal light is 94%. In low-light conditions, it showed lower performance. In the first test, the model achieved 74% accuracy by recognizing 20 classes, while in the second test, the accuracy dropped to 66% by recognizing 18 classes. Confusion matrix testing is used to evaluate the Accuracy, Recall, and Precision levels in model training using Decision Tree.

Abstract

Uncertainty in crop yields due to environmental factors remains a major challenge in Indonesia's agricultural sector. This study aims to compare the performance of the Random Forest Regressor and Decision Tree Regressor algorithms in predicting cultivated crop yields. The dataset used was sourced from Kaggle, consisting of 300,000 rows with features such as crop type, soil type, rainfall, fertilizer use, irrigation, and weather conditions. The system was developed using Python and Streamlit. The methodology includes data preprocessing, model training, and evaluation using the Mean Absolute Error (MAE) metric. The test results show that the Decision Tree Regressor achieved a lower MAE (0.43) compared to the Random Forest Regressor (0.48), resulting in more accurate predictions on this dataset. Feature analysis indicates that rainfall and crop type are the most influential factors. Although Random Forest is generally known for its stability, this study demonstrates that Decision Tree can outperform it within the context of the dataset used. The developed system is expected to assist farmers and policymakers in planning agricultural production more efficiently and in a data-driven manner.
