Abstract

Batam City, an industrial hub in the Riau Kepulauan Province, Indonesia, boasts a significant immigrant population and occupies a strategic position along international shipping routes, bordering other nations. The city experiences one of the fastest population growth rates in Indonesia, including a surge in student numbers. The current number of elementary school students and the number of junior high and high school students in the next few years play an important role  for sustainable development, aligning with the government's Golden Indonesia Vision 2045, which aims to cultivate a high-quality and productive generation. To support this initiative, accurate projections of student numbers, particularly in high schools, are essential. This study focuses on forecasting the number of senior secondary school students in Batam City for 2035. Utilizing data from the Batam City Statistics Agency spanning 2019 to 2022. To achieve the research goals, the authors employed the Smoothing Exponential Brown Parameter to project figures for 2023-2035. The optimal projection was achieved with α=0.99, estimating 29,988 high school students in Batam City by 2030 and 34,775 by 2035. The research findings indicate that the Batam City government is highly recommended to formulating the policies and planning to establish 18 new secondary schools, addressing potential shortages in classrooms and educational institutions. Additionally, the study urges the local government need to ensure the availability of 1,879 teachers of secondary school by 2035 in Batam City. These projections can assist the administration in effectively planning for educational resources to deliver quality education by 2025, contributing to the realization of the Golden Indonesia Vision 2045

Abstract

The quality management system is an approach in realizing a quality assurance program that is very important to be placed as scientific studies in the context of measuring and predicting the readiness of educational institutions. The purpose of this study is to determine the planning for implementing the SPMP implementation in order to improve the quality of schools at SMK Negeri 3 Kemaritiman Biak Numfor., Garut Regency. This research was conducted using a qualitative approach. The method used is descriptive analysis. Techniques and research instruments using observation, interviews and documentation. While the analysis technique is done through data reduction, data display and drawing conclusions. The results of the study indicate that quality planning is carried out in several steps, namely quality mapping through school self-evaluation (EDS) activities, which are followed by preparation of compliance plans, implementation of education quality, evaluation of education quality and standard setting so that it can describe school quality accurately. Implementation of education quality assurance that has been planned to fulfill eight National Education Standards.

Abstract

Indonesia is an archipelagic country with more than seventeen thousand islands, both in the interior and border areas. The border area is directly or indirectly a barrier to other countries. The purpose of this study is to provide an overview for readers to conduct forecasting method research. This study aims to describe the profile of the spread of the virus and provide input on education policies in border areas for forecasting. This research may need to be more thematically up-to-date and slow in publication. Still, researchers believe this is useful for policymakers to determine policies from reading existing patterns using equations in forecasting methods. Especially in the era of disruption, which is full of uncertainty, knowledge like this is needed to make predictions. In this study, the characterization is divided into gender, age, occupation, and interaction. The results showed that the gender of COVID-19 patients in the border areas had the same proportion of both men and women, the age range of twenty to forty-eight years had a greater probability of being affected, employees/private sector were more dominant to be involved, groups and the most prevalent cause of transmission of COVID-19 is family interaction. In addition, using Brown's double smoothing exponential method shows that predictions for July, August, and November for suspects and patients with COVID-19 will increase. Thus, the recommendation from this research for the Education Office as a policy maker in border areas is that school learning activities should be postponed until conditions are feasible. Implementasi metode peramalan guna menentukan kebijakan model belajar mengajar saat pandemic di daerah perbatasanIndonesia merupakan negara kepulauan yang terdiri lebih dari tujuh belas ribu pulau, baik yang berada di pedalaman maupun di daerah perbatasan. Daerah perbatasan secara langsung atau tidak langsung menjadi pembatas dengan negara lain. Tujuan penelitian ini secara umum memberikan gambaran kepada para pembaca untuk melakukan sebuah penelitian metode peramalan. Secara kusus, dalam penelitian ini bertujuan untuk menggambarkan profil sebaran virus, dan memberikan masukan kebijakan pendidikan di daerah perbatasan atas peramalan yang dilakukan. Penelitian ini mungkin tidak up to date secara tema dan lambat dalam publikasi, namun peneliti berkeyakinan ini berguna bagi pengambil kebijakan untuk menentukan kebijakan dari membaca pola-pola yang ada menggunakan persamaan dalam metode peramalan. Apalagi di era disrupsi yang penuh dengan ketidak pastian, pengetahuan seperti ini sangat diperlukan untuk memprediksi. Dalam penelitian ini, karakterisasi dibagi menjadi empat yaitu jenis kelamin, usia, pekerjaan, dan interaksi. Hasil penelitian menunjukkan bahwa jenis kelamin pada pasien COVID-19 di daerah perbatasan memiliki proporsi yang sama baik laki-laki maupun perempuan, rentang usia dua puluh sampai empat puluh delapan tahun memiliki kemungkinan lebih besar untuk terkena, pegawai/swasta lebih dominan untuk terkena, kelompok lain dan juga penyebab paling dominan penularan COVID -19 adalah interaksi keluarga. Selain itu dengan menggunakan metode double smoothing exponential Brown menunjukkan bahwa prediksi Juli, Agustus hingga November kondisi suspek dan pasien COVID -19 akan naik. Dengan demikian, rekomendasi dari penelitian ini  untuk Dinas Pendidikan sebagai pengambil kebijakan di daerah perbatasan adalah kegiatan belajar di sekolah sebaiknya ditunda hingga keadaan sudah bisa dikatakan layak.

Abstract

Although the demand for English proficiency in the workplace is increasing, limited research has examined its effects on employees' self-efficacy and job performance. English skills are essential for communication, productivity, and career advancement, yet their Influence on workplace outcomes remains understudied. This study investigates the relationship between employees' English self-efficacy and their professional performance using a mixed-methods design. A closed-ended survey was administered to 32 employees across five companies, and additional qualitative insights were collected from three managerial leaders. Quantitative data were analyzed through statistical correlation, while qualitative data were examined using thematic analysis. Findings show a strong correlation (r = .57) between English self-efficacy and job performance, indicating that employees who feel confident in their English abilities tend to perform more effectively. Managers also emphasized that English proficiency is especially important for supervisory and managerial roles. The study concludes that higher English self-efficacy positively contributes to job performance. However, its scope is limited by a small sample drawn from an electronics manufacturing company and by feedback from only three managerial interviewees, reducing the generalizability of the findings. Future research should explore a broader range of international workplace contexts to better understand how learning communities and vocational training can strengthen employees' language skills and performance.
