Abstract

Implementing the dual banking system in Indonesia offers options for customers to use banking services. Before selecting which service to use, customers should perceive each bank's advantages and disadvantages. It can be carried out by conducting a performance evaluation of each bank that generates high profitability measured by the Return on Assets (ROA) value. This study aims to perform internal and external factors analysis that affect bank profitability and to compare profitability between Islamic and Conventional banking in Indonesia using the Vector Error Correction Model (VECM) method. The result shows that variable Capital Adequacy Ratio (CAR) and Financing to Deposit Ratio (FDR) have a significant positive effect on Islamic Model in the long term, whereas policy rate and oil price (COP) hold a significant negative effect. In the Conventional Model, variable CAR, policy rate, and COP hold a significant positive effect, while the exchange rate shows a negative effect. FEVD results indicate that in Islamic Model, the diversity of banking profitability can be explained by various variables, indicating that Islamic banking is more engaged in the real sector than conventional banking.

Abstract

This study analyzes the relationship between various dimensions of globalization, economic growth indicators, inequality, and poverty in Indonesia using a VECM framework. All variables are stationary at the first difference, and the Johansen cointegration test identifies four cointegrating vectors, indicating a long-run equilibrium among poverty (POV), FDI, inequality (GR), unemployment (UE), economic openness (IEG), economic cooperation (IEC), and social openness (ISG). Based on the Akaike Information Criterion (AIC), a lag order of two is selected, and the VAR stability test confirms that the model is valid. In the long run, FDI, GR, UE, IEG, and ISG significantly influence poverty, whereas IEC shows no significant effect. FDI, IEG, GR, and ISG contribute to poverty reduction, while UE increases poverty. No variable exhibits short-run significance, but the significant error correction term (ECT) reflects a gradual adjustment toward long-term equilibrium. The FEVD results show that up to the tenth period, the variance in POV is primarily explained by POV itself (63.97%), followed by ISG (15.77%), GR (12.76%), and UE (5.49%), whereas FDI, IEG, and IEC contribute less than 1%. Overall, poverty dynamics in Indonesia are largely driven by their own persistence, with additional contributions from social openness and inequality.

Abstract

Background: Desa Burai, Kecamatan Tanjung Batu, Kabupaten Ogan Ilir adalah kawasan wisata dengan produksi pertanian yang beragam, diantaranya adalah tanaman jambu air. Daun jambu air merupakan salah satu bahan alam yang memiliki sifat antioksidan tinggi, namun pemanfaatannya masih tergolong sedikit. Pengabdian ini bertujuan untuk meningkatkan pemanfaatan daun jambu air sebagai alternatif pengobatan sindrom metabolik. Metode: Upaya pencegahan ini dapat dilakukan secara tradisional menggunakan daun jambu air yang jarang dimanfaatkan dengan mengembangkannya menjadi teh dan saturasi untuk mendorong diversifikasi pemanfaatan tanaman herbal dan mengurangi efek samping yang ditimbulkan oleh penggunaan medikasi sintetik. Edukasi dan pelatihan dilakukan dengan metode pemberdayaan melalui pembinaan, pendampingan, dan pelatihan keterampilan membuat produk kaya antioksidan. Hasil: Dari hasil proses pembuatan teh, produk yang dihasilkan memiliki rasa yang tidak pahit, yang menandakan produk teh dan saturasi dapat dibuat dengan baik. Proses pendampingan masyarakat dalam pelatihan menunjukkan hasil yang positif berdasarkan nilai post test yang dilakukan setelah pelatihan. Kesimpulan: Masyarakat Desa Burai mampu menangkap pelatihan yang diberikan dan dapat menjelaskan manfaat minuman teh dan saturasi daun jambu air sebagai penanggulangan sindrom metabolik.
