Abstract

In this study, currency exchange rates became dependent variables, while inflation, interest rates, and gross domestic product (GDP) were considered as independent variables. The focus of the study lies on the exploration of currency exchange rates, which basically reflect the comparison or ratio between two different currencies. This study aims to establish the impact of inflation, interest rates, and GDP on currency exchange rates during the period 2018-2022. Quantitative methods, particularly multiple linear regression analysis, are used to examine the effect of the independent variable on the dependent variable. This analysis is prepared by testing classical assumptions. The sample consists of 60 data, which are used in Microsoft Excel 2019 and IBM SPSS Statistics 25 software for processing. The research findings indicate that, individually, “the inflation variable (X1) and interest rates (X2) do not exert an effect on the rupiah exchange rate (Y), while gross domestic product (GDP) (X3) does have an impact on the rupiah exchange rate (Y). Furthermore, the results of the coefficient of determination test reveal that inflation (X1), interest rates (X2), and GDP (X3) collectively contribute to a 17.5% effect on the rupiah exchange rate.”

Abstract

The integration of poultry farming and maggot cultivation was carried out with the Tui Jati Livestock Farmers Group in Central Lombok Regency to enhance farmers' skills in managing poultry waste, maggot cultivation, and improving poultry feed efficiency. The main challenges were the environmental pollution caused by poultry waste and the high cost of feed, which negatively impacts farmers' economy. The program aimed to assist in processing poultry waste into a medium for maggot farming, offering an efficient and sustainable alternative feed, reducing dependence on expensive commercial feed, and mitigating environmental pollution. The program also designed an integrated system for poultry and maggot farming through a processing facility and provided training on poultry waste management and maggot cultivation techniques. The methods included initial observation and mapping of conditions, thematic training on maggot egg hatching and cultivation, hands-on field guidance, and evaluation through pre-tests, post-tests, observations, and interviews. Evaluation results showed an improvement in farmers' knowledge and skills, with average scores rising to a "good" category on the Likert scale. Farmers successfully cultivated maggots independently, from egg hatching to the laying phase, using poultry waste as a medium in the Maggot Center. In conclusion, the integration of maggot farming in poultry production contributed significantly to reducing environmental pollution and improving farmers' economies. The success of the program was largely due to the active participation of the Tui Jati Livestock Farmers Group at every stage of implementation. Achievements include increased knowledge and skills in maggot farming and the creation of new economic opportunities that support sustainable livestock farming and improve community welfare
