Abstract

This study aims to analyze the effect of capital structure and sales growth on profitability in real estate companies listed on the Indonesia Stock Exchange for the 2021–2024 period. This study used a quantitative approach with an explanatory method and a sample of 62 companies selected through purposive sampling, resulting in 248 data observations. Data were analyzed using SPSS version 29. The results showed that capital structure had a negative and significant effect on profitability, while sales growth did not significantly affect profitability. Simultaneously, capital structure and sales growth significantly affected profitability. The research findings indicate that the profitability of real estate companies is more influenced by the company's ability to manage its funding structure than by sales growth. This indicates that increased sales will not necessarily increase profitability if it is not balanced by effective cost management and funding sources.

Abstract

Pengaruh Trust dan E-Security Seals Terhadap Minat Pembelian Ulang Melalui Situs Online Shopee Di Morowali Dibimbing oleh Syamsul Bahri Dg. Parani. Penelitian ini bertujuan untuk mengetahui pengaruh trust dan e-security seals terhadap minat pembelian ulang melalui situs online Shopee di Morowali. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian asosiatif kausal. Populasi dalam penelitian ini adalah masyarakat Morowali yang pernah melakukan transaksi melalui aplikasi Shopee. Teknik pengambilan sampel menggunakan purposive sampling dengan jumlah responden sebanyak 60 orang. Metode analisis data yang digunakan adalah regresi linear berganda dengan terlebih dahulu melakukan uji instrumen dan uji asumsi klasik. Hasil penelitian menunjukkan bahwa trust dan e- security seals secara simultan berpengaruh signifikan terhadap minat pembelian ulang melalui situs online Shopee di Morowali. Secara parsial, trust berpengaruh signifikan terhadap minat pembelian ulang. Demikian pula, e-security seals juga berpengaruh signifikan terhadap minat pembelian ulang. Hal ini menunjukkan bahwa semakin tinggi tingkat kepercayaan konsumen dan semakin baik persepsi terhadap jaminan keamanan elektronik, maka semakin tinggi pula minat konsumen untuk melakukan pembelian ulang melalui situs online Shopee.

Abstract

Critical thinking skills are important in physics education because they encourage students to analyze, evaluate, and apply concepts in real life. However, the assessment instruments used still focus on memory skills and have not integrated the local cultural context. In fact, many physical phenomena, including heat transfer, can be seen in cultural activities such as traditional food preparation. Previous studies have emphasized the development of questions based on higher-order thinking skills, literacy, and numeracy, but few have linked them to culture. Therefore, it is necessary to develop ethno-physics-based critical thinking questions on heat so that assessments not only measure conceptual mastery but also connect physics with local wisdom. This study aims to analyze the validity, reliability, discriminating power, and difficulty level of ethno-physics-based critical thinking questions on the topic of heat, as well as to test their practicality. The method applied is Tessmer's Research and Development (R&D) model, with stages including Preliminary, Self-Evaluation, and Formative Evaluation. The results of the development show that the resulting test items are valid. The reliability value obtained is 0.75, which is classified as high. In terms of difficulty, the majority of questions are categorized as moderate and a small portion are easy. The discrimination power of the test items varies between very good, good, and fair. Overall, all items successfully differentiated between students' abilities, and none of the items failed to differentiate. In terms of practicality, the use of these items is classified as very practical.
