Abstract

Selip roda adalah salah satu kesulitan yang dihadapi ketika menggunakan robot luar ruangan yang menggunakan roda. Selip roda dapat terjadi ketika kecepatan roda tidak sesuai dengan kondisi lanskap. Kontrol cengkeraman sangat penting untuk menjaga keandalan dan mencegah selip roda. Penyesuaian berdasarkan jenis medan diperlukan untuk memastikan fungsionalitas optimal karena nilai kontrol cengkeraman dapat berbeda untuk berbagai jenis medan. Dengan demikian, sistem prediksi medan yang terintegrasi sangat penting bagi robot luar ruangan untuk membantu menyesuaikan nilai kontrol cengkeraman yang telah diatur berdasarkan medan yang dihadapi. Metode visual melalui kamera robot dapat digunakan untuk mendeteksi medan. Tujuan penelitian ini untuk mendesain arsitektur Convolutional Neural Network (CNN) yang sesuai dalam prediksi jenis medan. Penelitian ini juga bertujuan untuk mengukur kesuksesan sistem dalam memprediksi medan yang dilalui oleh robot yang bergerak secara langsung. Model CNN yang dikembangkan berhasil mencapai tingkat keakuratan sebesar 95%. Sistem prediksi mampu melakukan prediksi secara langsung dengan rata-rata waktu 0.094 detik. Dalam pengujian keseluruhan sistem pada robot yang bergerak maju, akurasi mencapai 84.61%.

Abstract

General background: The cultivation of empathy and creativity is crucial in secondary education, particularly in literary learning. Specific background: However, many students exhibit limited empathetic engagement and creative expression when learning short stories. Knowledge gap: Previous studies on Project Based Learning (PjBL) in literature often overlook its differential effects on empathy versus creativity. Aims: This study investigates the effectiveness of PjBL in enhancing empathy and creative writing skills through short story learning in Grade VIII students of SMP Negeri 1 Plumbon Cirebon. Results: Using a quasi-experimental pretest–posttest control group design, data were collected via short story writing tests, empathy questionnaires, project assessments, and classroom observations, analyzed with paired t-tests, independent t-tests, and simple linear regression. Findings reveal that PjBL implementation followed the prescribed syntax, promoted active participation, and produced short stories rich in empathetic and creative elements. While empathy improved significantly within the experimental group, intergroup comparisons and regression indicated no statistically significant effect on empathy, but a significant positive effect on creativity. Novelty: This research distinguishes the distinct impact of PjBL on two character dimensions in literature learning. Implications: PjBL is a promising pedagogical strategy to foster students’ creative capacity in literary contexts. Highlights: Significant boost in students’ creative writing skills. Empathy improved but not statistically significant between groups. PjBL effectively engages students in literary learning. Keywords: Project Based Learning, Short Story, Empathy, Creativity, Secondary Education

Abstract

This study will analyze the Factors affecting the Profitability of Indonesia Stock Exchange (IDX) listed Plastic and Packaging Sub-Sector Manufacturing Companies between 2019-2023, Independent variables to be analyzed are External and Internal Factors affecting Company Profitability which are Exchange Rates, Inflation, BI Rate Interest Rates, Leverage and Company Size while Profitability is the Dependent Variable to be measured using Return on Assets (ROA). The analytical approach used is the Panel data Regression Model and the Coefficient of Determination via the Random Effect Model (REM) approach. The data in this study were gathered from the Financial Statements of the Plastic and Packaging Sub-Sector Manufacturing Companies Listed on the Indonesia Stock Exchange for the Period 2019-2023 using the Sampling Technique in this study using Purposive Sampling so that this study had a sample of 13 companies with 65 Financial Statement Data. The conclusion of this study indicates that BI Rate and Leverage Interest Rate have partially significant negative effects on profitability and Exchange Rate, Inflation and Company Size do not have partially significant negative effects on profitability. Meanwhile Exchange Rate, Inflation, BI Rate, Leverage and Company Size have Significant Impact on Profitability
