Abstract

This study aims to analyse poverty alleviation in Tarakan from the perspective of Ibn Khaldun's development theory. This research method uses descriptive qualitative methods, and all data is secondary. The research results show that Ibn Khaldun's development theory can be an idea in carrying out the development of the city of Tarakan by eliminating people's economic difficulties, providing convenience, and creating prosperity. Guarantee the enactment of sharia values ​​that help society instil good qualities towards the balance of resources. Human resource development affects poverty reduction. Wealth does not grow if it is hoarded and stored. It will grow and develop if it is spent for the benefit of society, given to those entitled, and becomes a solution.

Abstract

Dalam artikel ini, metode analisis homotopi digunakan untuk menyelesaikan suatu model Lotka-Volterra dari dua spesies yang bersaing. Dalam hal ini akan ditentukan suatu penyelesaian berupa semi-analitik dari model tersebut. Metodologi penelitian yang dilakukan diawali dengan mendefinisikan suatu operator linear berdasarkan model Lotka-Volterra yang ditinjau, kemudian mengonstruksi suatu persamaan deformasi. Berdasarkan persamaan deformasi ini diperoleh suatu hampiran penyelesaian. Penyelesaian hampiran dari model yang dikaji menunjukkan galat yang relatif kecil. Dalam artikel ini juga diberikan simulasi bahwa jika tingkat intrinsik spesies satu mengalami peningkatan dari 8% hingga 50%, tetapi tingkat intrinsik spesies dua dibuat tetap, maka hasil simulasi menunjukkan bahwa jumlah populasi spesies satu mengalami peningkatan, sedangkan jumlah spesies dua mengalami penurunan.

Abstract

Dalam tulisan ini dikembangkan model pengendalian hama tanaman terpadu yang didasarkan pada model mangsa-pemangsa Leslie-Gower. Dalam model ini terdapat unsur pertahanan tanaman (tanaman yang mengeluarkan senyawa/bau) yang akan mampu mengusir sebagian hama yang ada di sekitarnya. Populasi yang terlibat dalam model ini yaitu populasi tanaman, populasi hama, dan populasi pemangsa hama. Tujuan tulisan ini adalah menentukan pengaruh pertahanan tanaman terhadap dinamika populasi yang terlibat. Dari analisis, menghasilkan empat titik tetap. Simulasi dilakukan untuk melihat pengaruh perubahan koefisien efisiensi pertahanan tanaman terhadap kestabilan titik tetap yang diperoleh. Telah ditunjukkan bahwa jika nilai koefisien efisiensi pertahanan tanaman diperbesar, mengakibatkan hama dan pemangsa hama menuju kepunahan dan populasi tanaman akan bertambah banyak.

Abstract

In this article, we derive simple formulations of the eigenvalues, determinants, and also the inverse of circulant matrices whose entries in the first row form an arithmetic sequence. The formulation of the determinant and inverse is based on elementary row and column operations transforming the matrix to an equivalent diagonal matrix so that the formulation is obtained easily. Meanwhile, for the eigenvalues formulation, we simplify the known result of formulation for the general circulant matrices by exploiting the properties of the cyclic group induced by the set of all roots of as the set of points in the unit circle in the complex plane, and also by considering the specific property of arithmetic sequence. Then, we construct an algorithm for the eigenvalues formulation. This algorithm shows a better computation compared to the previously known result for the general case of circulant matrices.

Abstract

Matriks skew-circulant adalah matriks segi yang entri terakhir setiap baris berpindah ke posisi utama dan berganti tanda disertai pergeseran semua entri lainnya ke posisi berikutnya. Dalam artikel ini, entri dari matriks circulant berupa entri barisan bilangan geometri. Tujuannya adalah merumuskan suatu formulasi sederhana dari determinan, invers, dan nilai eigen dari suatu matriks skew circulant. Formulasi determinan ditentukan dengan menerapkan serangkaian operasi baris dasar dan kolom dasar sampai diperoleh matriks diagonal. Langkah untuk mencari invers dilakukan dengan mengadaptasi metode dalam mencari determinan dan ekuivalensi baris dan kolom pada matriks. Dalam mencari nilai eigen digunakan konsep akar kesatuan (roots of unity) dan subgrup siklik.

Abstract

This study aims to design a QR-based ticket booking application at Diana Waterpark, which is expected to increase operational efficiency and improve visitor experience. Using a quantitative descriptive approach, data were collected through questionnaires distributed to 30 respondents who visited Diana Waterpark. The results of the application design indicate that the use of QR technology can reduce visitor waiting time and speed up the ticket booking process. In addition, this application is designed to provide convenience for users with an intuitive interface and fast booking system. However, this study also identified several areas that need to be improved, such as the ticket information management system and improving transaction security features. Overall, the design of this application is expected to have a positive impact on visitor satisfaction and loyalty, as well as provide practical solutions in ticket and ride management at Diana Waterpark. This study recommends that managers continue to develop applications with a focus on improving security systems and more integrated application features.

Abstract

This study examines the role of waqf banks in Islamic finance through a comparative analysis of their implementation and social impact in Indonesia, Malaysia, and Turkey. As an innovative instrument combining philanthropic principles with modern banking mechanisms, waqf banks are positioned to address gaps in social financing and support long-term socio-economic development. The findings reveal that Malaysia has successfully institutionalized waqf banks in funding social projects, such as scholarships and healthcare infrastructure, supported by comprehensive regulatory frameworks. In Turkey, waqf assets have been productively managed through formal financial channels, reflecting strong integration between traditional endowment models and contemporary asset management practices. Indonesia, meanwhile, is in a developmental phase, with various initiatives underway but still facing regulatory and institutional challenges. The study further highlights the potential of strategic collaboration between waqf banks and other Islamic financial institutions—such as Islamic banks and zakat agencies—to enhance liquidity, operational efficiency, and sustainability. By offering both conceptual insights and practical implications, this research contributes to a deeper understanding of waqf banking as a catalyst for inclusive development and proposes policy recommendations tailored to each national context.
