Abstract

The existence of competition among sharia banks is one of the effects that occur with the development of sharia banks. The purpose of this study is to analyze the efficiency of Sharia banks in Indonesia. Understanding efficiency is important because if banks are always operating at full efficiency, the fewer inputs they use, the greater the output they achieve. Output is measured by total earning assets, while the inputs used are total deposits and total operating expenses. A data envelopment analysis with input-oriented and variable returns to scale is used to achieve the objective. The result shows that of the twelve Sharia banks studied, four are considered to be the most efficient.   Adanya persaingan antar bank syariah merupakan salah satu dampak yang terjadi dengan berkembangnya bank syariah. Tujuan dari penelitian ini adalah untuk menganalisis efisiensi bank syariah di Indonesia. Memahami efisiensi menjadi penting karena jika bank selalu beroperasi pada tingkat efisiensi penuh, maka semakin sedikit input yang mereka gunakan, semakin besar output yang mereka capai. Output diukur dengan total aktiva produktif, sedangkan input yang digunakan adalah total simpanan dan total biaya operasional. Untuk mencapai tujuan tersebut, digunakan analisis data envelopment dengan pendekatan input-oriented dan variable returns to scale. Hasilnya menunjukkan bahwa dari dua belas bank syariah yang diteliti, empat bank dianggap paling efisien.

Abstract

Outcome-based education (OBE) means clearly focusing and organizing everything in an educational system around what is essential for all students to be able to do successfully at the end of their learning experiences. This means starting with a clear picture of what is important for students to be able to do, then organizing curriculum, instruction, and assessment to make sure this learning ultimately happens. Therefore, this study aims to analyze the perceptions of lecturers and students regarding the implementation of OBE in the Faculty of Engineering. There are six variables used in this study, i.e., statement of student’s achievement, relevance of student’s achievements, subject’s preparation, teaching and learning process, supporting facilities, and evaluation. The indicators are generated according to the literature review and interview with experts, resulting 51 indicators. There are 103 students and 79 lecturers to be selected as the respondents. The respondents are asked about their opinions regarding the OBE implementation according to those indicators. Results show that from the perspective of lecturers, OBE is very well implemented regarding the variables of statement of student’s achievement, relevance of student’s achievements, and teaching and learning process; while the others are well implemented. However, from the perspective of students, OBE is fairly implemented regarding the variable of supporting facilities; while the others are well implemented.

Abstract

Procurement is important in a company because it will directly affect how much a company can reduce costs. One of the activities in the procurement process is purchasing. PT XYZ has never conducted a supplier analysis or analysis of items purchased from suppliers. PT XYZ only purchases items daily; if managed properly, it can save the company's expenses and improve supplier relationships. This study aims to formulate purchasing strategies by implementing the Kraljic Portfolio Matrix (KPM). KPM has been widely applied to various cross-sectoral companies to manage suppliers more effectively. KPM divides items provided by suppliers into four quadrants based on supply risk and profit impact to minimize supply risk and maximize purchase profit. Thirty-five sup-pliers were analyzed in this study. The result shows that of the four KPM quadrants, three quadrants are filled, namely the non-critical quadrant (containing 12 suppliers), bottleneck (14), strategic (9), and none of the suppliers located in the leverage quadrant. Purchasing strategies based on these three quadrants are then formulated, and a total of seven strategies are produced. An analysis of the dominance of buyers and suppliers is also given to find out the relationship and balance of power between these parties.

Abstract

Education plays a pivotal role in national development, and assessing its quality is crucial. One widely recognized international assessment is the OECD's PISA, which evaluates mathematics, science, and reading abilities among 15-year-old students globally. In 2018, Indonesian students scored below the OECD average, highlighting deficiencies in the education system. This study investigates the determinants influencing Indonesian students' PISA scores using 2018 data. Multiple linear regression is employed to analyze three models: mathematics, science, and reading scores as dependent variables. Independent variables include age, gender, study time in mathematics, science, and reading, economic, social, and cultural status, family wealth, home ICT ownership, teacher feedback, and school discrimination perception. The findings reveal varying influences on PISA scores across domains: age does not affect mathematics scores, gender does not affect science scores, and all variables significantly impact reading ability scores at the 5% confidence level.
