Abstract

Kegiatan praktikum dalam pendidikan kimia memegang peranan penting dalam membentuk keterampilan dan pemahaman mahasiswa terhadap konsep-konsep dasar kimia. Mahasiswa baru sering mengalami kesulitan dalam mengoperasikan alat laboratorium, melakukan pengukuran yang tepat, serta menerapkan prosedur kerja yang aman dan benar. Tujuan utama kegiatan ini adalah untuk meningkatkan keterampilan dasar praktikum kimia bagi mahasiswa baru melalui pelatihan intensif berbasis praktik langsung di laboratorium. Metode pelaksanaan kegiatan mencakup sesi pelatihan teoritis, demonstrasi, dan praktik mandiri dengan pendampingan oleh dosen dan asisten laboratorium. Kegiatan ini diikuti oleh 40 mahasiswa baru yang dibagi ke dalam 4 kelompok, masing-masing terdiri atas 10 peserta. Setiap kelompok mengikuti pelatihan alat laboratorium, teknik dasar pengukuran, serta prosedur keselamatan kerja. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman konsep dasar dan keterampilan teknis, yang tercermin dari hasil praktik dan peningkatan skor post-test peserta. Mahasiswa menyatakan bahwa kegiatan ini membantu mereka lebih percaya diri dalam menghadapi praktikum yang sesungguhnya. Kegiatan ini memberikan kontribusi penting dalam membangun kesiapan awal mahasiswa baru melalui keterlibatan aktif dalam lingkungan pembelajaran laboratorium yang terstruktur

Abstract

Inflation is generally the tendency for the prices of goods and services to rise continuously. An artificial neural network (ANN) is an information processing model that closely resembles how an organism's memory system works, such as information transmission processes in the brain. Forecasting is the activity of determining future events based on past data. A time series is a set of observations that occur consecutively in the correct amount of time based on a time index. The data used in this study are Indonesian monthly inflation data. Extreme Learning Machine (ELM) is an artificial neural network approach that uses a single hidden layer feedforward neural network architecture (SLFN). The advantages of ELM over traditional learning algorithms are learning speed, improved generalization performance, and simplified implementation. An error value of RMSE of 0.1992215 was obtained based on the analysis performed using the Extreme Learning Machine (ELM) method.

Abstract

Indonesia is a country with an open economy, one of the sources of foreign exchange needed by a country with an open economy is exports. Cocoa is one of Indonesia's main export commodities that makes an important contribution to the country's economy, but the value of Indonesian cocoa exports fluctuates, that is there are inconsistent changes from time to time. The purpose of this study is to determine the results of forecasting the value of Indonesian cocoa exports, as well as to determine the best method for forecasting. This research compares the ARIMA and Single Exponential Smoothing methods to determine the best forecasting method. The best method is selected based on the smallest MAPE value. Based on the results of data analysis, the best forecasting model using the ARIMA method is the ARIMA (1, 0, 1) model, which has a MAPE value of 10.38060%. Meanwhile, the best forecasting model using the Single Exponential Smoothing method is with α = 0.16, which has a MAPE value of 10.92874%. So that the best method for forecasting the value of Indonesian cocoa exports is the ARIMA method.

Abstract

Support Vector Machine (SVM) is a machine learning method for classifying data that has been successfully used to solve problems in various fields. The risk minimization principle used can produce an SVM model with good generalization capabilities. The problem with the SVM method is the difficulty in determining the optimal SVM hyperparameters. This research uses Genetic Algorithm (GA) to optimize SVM hyperparameters. GA optimization on SVM is used to classify hypertension. From the result of classification analysis using GA, it shows good accuracy value performance, namely 100% compared to using only SVM.

Abstract

The increasing number of hypertension patients and the threat of serious complications make hypertension one of the leading causes of death worldwide. Early prevention is currently considered one of the best solutions. Early prevention through early detection can be achieved by utilizing machine learning technology. XGBoost is a machine learning algorithm based on gradient boosting machines. XGBoost applies regularization techniques to reduce overfitting and has faster execution speed as well as better performance. The objective of this research is to classify hypertension levels using the XGBoost method and leveraging hyperparameter tuning for optimization. In this study, the hyperparameter optimization technique used is gridsearchCV. The evaluation results of the XGBoost classification method using the best combination of parameters show good performance, where the XGBoost model achieves an accuracy of 93.3%, Precision of 97%, Recall of 92%, F1-Score of 93%, and AUC value of 0.935. This implies that the classification of hypertension levels in patients at Pelamonia Makassar Hospital can be well or accurately classified using the XGBoost method.
