This research explores the impact of institutional ownership, managerial ownership, and the proportion of independent commissioners on firm performance, with earnings quality serving as a moderating variable. The study draws on a sample of companies that undertook Initial Public Offerings (IPOs) in 2019 on the Indonesia Stock Exchange, utilizing data spanning the years 2019 to 2023. A multiple linear regression model was employed to assess both direct effects and interaction effects moderated by earnings quality. The findings indicate that institutional ownership and the presence of independent commissioners exert a statistically significant influence on company performance, with earnings quality enhancing these relationships. This study enriches the discourse on corporate governance mechanisms within newly public firms and offers practical insights for both market regulators and investors.

This study was conducted to examine the effect of job promotion and communication style on employee performance at Metro Fried Chicken Pangkalpinang branch. Quantitative method with multiple linear regression analysis was applied to determine the correlation and influence of the two variables simultaneously and partially. The results showed that job promotion and communication style have a positive and significant effect on employee performance, with an R-squared value of 0.895 which indicates that 89.5% of variations in employee performance can be explained by these two variables. These findings contribute to the development of human resource management, especially in improving employee performance with fair promotions and effective communication. It is recommended that companies pay attention to aspects of promotion fairness and improve the quality of leadership communication to achieve optimal performance.

The purpose of this study is to assess the computational thinking skills of fourth-grade elementary students within the framework of mathematics instruction. Computational thinking is a crucial 21st-century competency that should be cultivated from an early age, particularly in solving mathematical problems. This study adopts a descriptive quantitative method using a written test instrument developed based on four key computational thinking components: decomposition, pattern recognition, abstraction, and algorithmic processes. The participants in this research were fourth-grade students from a selected elementary school. The results indicate that most students demonstrate a moderate level of computational thinking. Among the assessed indicators, decomposition was the most successfully achieved, while algorithmic thinking was the least mastered. These results highlight the importance of integrating contextual and problem-based learning strategies to further enhance students’ computational thinking abilities in mathematics education.

Indonesian Migrant Workers (PMI) abroad often face various social, legal, and cultural challenges that can increase their vulnerability in everyday life. One effort to minimize these vulnerabilities is through the establishment of regional community organizations as a platform for solidarity, advocacy, and cultural identity preservation. This community service activity aims to assist in the formation of the Ikatan Warga Ponorogo di Hong Kong (IWPH) — an association of PMI from Ponorogo working in Hong Kong. The methods employed include community needs assessment, facilitation of organizational meetings, formulation of organizational statutes and bylaws, and basic community-based advocacy training. The results of this activity showed high enthusiasm among PMI from Ponorogo to participate in this community as a forum for sharing information, social protection, and preserving regional cultural traditions abroad. Moreover, IWPH has begun to actively voice issues faced by PMI, such as overcharging, gender-based violence, and unclear employment contracts. The establishment of IWPH is expected to serve as a model for strengthening social networks and advocacy based on regional community groups, enhancing the bargaining power of Indonesian migrant workers abroad. This activity also reflects the contribution of higher education institutions in supporting the protection and empowerment of Indonesian migrant workers in various destination countries.

This study aims to examine the effectiveness of the LingoDeer application as a learning medium for basic level Japanese language learners. A quantitative approach was employed using a One Group Pretest Posttest design involving 50 students from the Vocational School of IPB University. The research instrument consisted of pretest and posttest assessments focusing on three key areas: vocabulary, grammar, and reading skills. Based on the results of the paired sample t-test, a significant improvement was found in all aspects after the use of the application, with the average score increasing from 60.97% to 81.25%. The greatest improvement was observed in vocabulary, followed by reading and grammar. These findings suggest that LingoDeer, with its structured learning system, spaced repetition feature, and interactive exercises, can effectively support the development of Japanese language skills at the beginner level. This study is expected to serve as a reference for educators in selecting appropriate technology-based learning tools to enhance language acquisition.

Proses rekrutmen tenaga kesehatan di Rumah Sakit Islam Ar-Rasyid Palembang masih dilakukan secara manual, menyebabkan inefisiensi dalam manajemen data pelamar, penjadwalan wawancara, dan komunikasi.

Indeks Prestasi Kumulatif (IPK) merupakan indikator utama dalam menilai keberhasilan akademik mahasiswa. Berbagai faktor, termasuk kesehatan mental dan fisik, berkontribusi terhadap pencapaian ini. Penelitian ini bertujuan untuk membangun model prediksi IPK menggunakan algoritma Decision Tree dan Random Forest berbasis Feature Engineering. Proses feature engineering mencakup feature selection untuk memilih fitur paling relevan, diikuti oleh feature extraction yang menyederhanakan fitur menjadi dua kategori utama: kesehatan mental dan fisik. Data diperoleh melalui survei terhadap 7.022 mahasiswa dari berbagai universitas luar negeri, mencakup faktor usia, jurusan, tingkat stres, kecemasan, serta pola tidur, aktivitas fisik dan lain sebagainya. Model prediksi dikembangkan menggunakan Decision Tree dan Random Forest, dengan evaluasi akurasi kedua algoritma. Hasil penelitian menunjukkan bahwa Random Forest memiliki akurasi lebih tinggi dibandingkan Decision Tree. Faktor kesehatan mental, terutama tingkat stres, memiliki pengaruh signifikan terhadap prediksi IPK, disusul oleh pola tidur. Studi ini menegaskan bahwa pemantauan kesehatan mental dan fisik mahasiswa dapat meningkatkan pencapaian akademik. Temuan ini diharapkan dapat membantu institusi pendidikan dalam merancang strategi dukungan akademik berbasis kesehatan mahasiswa.

Students' understanding of mathematical concepts is still a challenge, especially in solving problems that require procedural and conceptual understanding, such as on the topic of circles. This study aims to analyze the types of errors made by students in solving mathematical problems on the topic of circles using the Newman's Error Analysis (NEA) procedure. The approach to this study is descriptive qualitative, conducted at SD 050661 Kwala Bingai with 20 subjects of grade VI-A. Data were collected through written tests and analyzed using five stages of NEA: reading errors, understanding, transformation, process skills, and writing final answers. The results of the study showed that most students made errors at the stages of understanding, transformation, and process skills. Factors causing errors include lack of conceptual understanding, procedural errors, and inaccuracy in solving problems. The conclusion of this study shows the need for an active role for teachers in identifying and overcoming student errors through appropriate teaching methods, especially on the topic of circles. This study is expected to provide an overview for teachers in designing appropriate learning strategies to improve students' understanding of mathematical concepts.
