Abstract

Background: Academic achievement reflects the success of higher education. However, data from LLDIKTI Region VI Central Java (2022) showed a decline in the average GPA of nursing students at several private universities, including Sultan Agung Islamic University (UNISSULA) Semarang. This raises concerns about the effectiveness of the learning process. One factor that may influence academic performance is the quality of interpersonal communication between lecturers and students. Effective communication, involving the exchange of information, feelings, and meaning, is essential in creating a supportive learning environment. Objective: This study aimed to examine the relationship between lecturers’ interpersonal communication skills and students’ academic performance at UNISSULA. Method: A quantitative cross-sectional design was used, involving 122 undergraduate nursing students from the 2023 cohort selected through simple random sampling. Data were collected using a 14-item interpersonal communication questionnaire and analyzed with Spearman’s rank correlation. Result: The results showed that 59% of students rated lecturers’ communication as very good, and 49.2% had high GPAs. A significant correlation was found (p = 0.001) Conclusion: Interpersonal communication of lecturers is important to enhance students' motivation, understanding, and engagement. Therefore, communication training is necessary to support the quality of education and academic achievement.

Abstract

This research aims to describe the application of an individual approach in learning Islamic education and its influence on the learning outcomes of junior high school students. This type of research is quantitative research. It is said to be quantitative research because this research uses the concept of variables. In data collection activities, the measuring tools or instruments used in this research used test techniques. The data processed is in the form of numbers obtained from the results of pretest and posttest students in junior high schools. The results of the research on the influence of the individual approach on student learning outcomes in the subject of Islamic education in junior high schools, namely first, the influence of the individual approach on the learning outcomes of students at state junior high school, the results of the analysis obtained t=6.24 and t table=1.89, then the hypothesis in this study is accepted, so it can be concluded that the learning outcomes pretest higher than the yield pretest before learning the individual approach. Second, the learning outcomes of Islamic education for students who were taught using an individual approach were higher compared to the control class who were taught using conventional methods. The average score of experimental class students was 80.205 while the average score of control class students was 67.27.

Abstract

This research is motivated by problems that UMKM has in financial accounting calculations due to limited knowledge about cost classification, which must be included in the calculation of the cost of production so that the resulting selling price is less than optimal. This study aims to determine the accuracy in classifying costs in calculating the cost of production and determining the selling price of the screen printing t-shirt product applied by Pangestu Production whether or not it is appropriate with cost accounting. The research object focused on cost reports during the screen printing t-shirt production process. This research uses a quantitative approach with descriptive methods. The conclusion of this study is that the calculations applied by Pengstu Production and the calculations by the researchers have a slight difference, this is because the company has several costs when production is not included, this results in the selling price applied by the company being less than optimal. For manual t-shirt screen printing, based on analysis calculations, the selling price is IDR 61,800 while the company selling price is IDR 61,000. The cause of the difference in selling prices is that the company does not calculate depreciation costs and some costs of auxiliary raw materials are ignored.

Abstract

Abstrak - Penelitian ini mengembangkan sistem prediksi harga mobil bekas menggunakan Algoritma Random Forest dengan menggunakan dataset Car Dekho Used Car Prices yang diperoleh dari platform Kaggle. Himpunan data tersebut mencakup 15411 row data mobil dengan 14 atribut, dan memiliki total data sebanyak 46.322. Proses penelitian meliputi data collecting, exploratory data analysis, data preprocessing (pengecekan missing values dan encoding variabel kategorikal), pembagian data menggunakan train-test split pembagian ini dilakukan dengan perbandingan data Training set (80%) dan data Testing set (20%). Hasil analisis menunjukkan bahwa fitur km_driven, vehicle_age, max_power, dan mileage memiliki pengaruh paling signifikan terhadap prediksi harga. Model Random Forest memberikan performa prediksi yang baik dengan nilai MAE sebesar Rupee130.309, RMSE sebesar Rupee212.103, dan R² sebesar 0,9505, yang berarti model mampu menjelaskan 95,05% variasi harga jual mobil bekas. Model kemudian diimplementasikan dalam aplikasi berbasis Streamlit yang memungkinkan pengguna memasukkan spesifikasi kendaraan dan memperoleh estimasi harga secara interaktif. Sistem prediksi ini dapat membantu konsumen dan pelaku bisnis dalam menentukan harga mobil bekas secara lebih akurat dan informatif.Kata kunci : Prediksi Harga Mobil Bekas; Random Forest; Machine Learning; Streamlit; Abstract - This research developed a used car price prediction system using the Random Forest algorithm with the Car Dekho Used Car Prices dataset obtained from the Kaggle platform. The dataset includes 15,411 rows of car data with 14 attributes, for a total of 46,322 data points. The research process includes data collecting, exploratory data analysis, data preprocessing (checking missing values and encoding categorical variables), and data division using train-test split. This division is carried out with a comparison of the training set (80%) and testing set (20%) data. The analysis results show that the features km_driven, vehicle_age, max_power, and mileage have the most significant influence on price prediction. The Random Forest model provided good prediction performance with an MAE value of IDR 130,309, an RMSE of IDR 212,103, and an R² of 0.9505, which means that the model was able to explain 95.05% of the variation in used car prices. The model was then implemented in a Streamlit-based application that allows users to enter vehicle specifications and obtain price estimates interactively. This prediction system can help consumers and businesses determine used car prices more accurately and informatively.Keywords: Used Car Price Prediction; Random Forest; Machine Learning; Streamlit;
