Abstract

Lidah buaya (Aloe Vera) mempunyai banyak manfaat salah satunya adalah untuk melembabkan kulit wajah karena mengandung zat aktif lignin. Untuk memudahkan penggunaan dari kulit wajah yang kering maka lidah buaya dibuat dalam sediaan masker gel peel off. Sediaan masker gel peel off termasuk ke dalam kategori produk kosmetik yang dapat membuat kulit menjadi lembab dan dapat mengangkat sel kulit mati pada wajah. Tujuan penelitian ini adalah memperoleh formula masker gel peel off yang baik, mengetahui uji fisik yang meliputi uji organoleptis, uji pH, uji homogenitas, uji daya sebar, uji waktu mengering dan uji stabilitas. Pembuatan ekstrak lidah buaya dilakukan dengan metode maserasi. Masker gel peel off ekstrak lidah buaya diformulasikan ke dalam 3 formula dengan perbedaan konsentrasi PVA yaitu F1 10%, FII 15%, FIII 20%. Setelah itu dilakukan evaluasi sifat fisik. Hasil penelitian didapatkan bahwa perbedaan persentase PVA pada setiap formula dapat mempengaruhi nilai daya sebar, dan uji waktu mengering pada sediaan. Formula yang baik pada penelitian ini adalah formula II dengan konsentrasi PVA 15%.

Abstract

This study aims to analyze the effect of Foreign Direct Investment (FDI) and exchange rates on the trade balance in the D-8 member countries (Bangladesh, Egypt, Indonesia, Iran, Malaysia, Nigeria, Pakistan, and Turkey) during the period 2000 to 2023. The method used is panel data regression with the Fixed Effect Model (FEM), Random Effect Model (REM), and Common Effect Model (CEM) approaches. The selection of the best model is done through the Chow, Hausman, and Lagrange Multiplier (LM) tests. The results show that the exchange rate has a significant effect on the trade balance in all models, indicating that exchange rate fluctuations are an important factor in determining the external trade balance. In contrast, FDI does not show a significant effect, so it has not made a real contribution to improving the trade balance of D-8 countries. Based on the results of the model selection test, the Random Effect model is declared the most appropriate for use in this study. However, all models show positive autocorrelation problems in the residuals, indicating the need for further approaches such as robust estimation to improve the reliability of the results. For the long-term effect, only the Exchange Rate has a significant effect on the Trade Balance, while all variables have no short-term effect. These findings provide policy implications that exchange rate stability and FDI direction are key to strengthening the trade balance of D-8 countries amidst global economic dynamics.
