Abstract

One of the current trending phenomena is performances or celebratory activities that are enlivened by lighting fireworks. The ignition of fireworks is usually done using a remote firework lighter (firing system) or even manually if the lighter is having problems/not working. It is still possible for operator accidents to be burned by fireworks. In addition to security issues, remote fireworks lighters are quite expensive. Therefore, to avoid security problems and the relatively high price, it is necessary to create or build a firework launcher system that is safe and inexpensive. The purpose of this study is to create a firework launcher application system for dangdut orchestra performances using an Android-based Arduino. In this study, an application has been produced that can make it easier for operators of fireworks lighters in dangdut orchestras to light fireworks more safely and cheaply. This application has been running smoothly and without problems. The benefit of this research is that the results of this application design can be used as a reference for other related research in the future.

Abstract

General Background: Agricultural transformation plays a critical role in driving economic development, particularly in rural areas. Specific Background: In Indonesia, the agricultural sector remains dominated by monoculture practices, limiting income diversification and resilience among farmers. Knowledge Gap: However, limited studies have examined how agricultural diversification specifically contributes to farmers’ welfare within regional economic development frameworks. Aims: This study aims to analyze the role of agricultural diversification in transforming local economies and improving the welfare of farmers. Results: The findings show that diversification increases productivity, enhances household income stability, and fosters resilience against price and climate shocks. It also supports the growth of rural agro-industries and market accessibility. Novelty: This study uniquely integrates socio-economic indicators with regional development models to demonstrate how diversification directly contributes to sustainable livelihood strategies. Implications: The research implies that policy frameworks should prioritize diversification strategies to achieve inclusive rural development and long-term welfare improvements for agricultural communities. Highlights : Diversification boosts income stability and resilience. It links agriculture with rural industrial growth. Policy support is crucial for sustainable impact. Keywords: Agricultural Diversification, Rural Development, Farmer Welfare, Economic Transformation, Indonesia

Abstract

Economic growth and unemployment rates are two macroeconomic indicators used to measure the government's success in improving the welfare of the people. Low economic growth will lead to high unemployment rates, which is in line with Okun's law. Over the past two years, East Java's economic growth has contracted but has not been accompanied by a decline in unemployment rates. This is interesting considering that reality does not align with theory. This study aims to examine the consistency of Okun's law with reality both before and after the COVID-19 pandemic. What is interesting about this study is that the COVID-19 pandemic has significantly changed the economy of East Java. This reality has actually improved the relationship between economic growth and unemployment rates. Based on Pearson's correlation coefficient, an inverse relationship was found between the pre- and post-pandemic periods. Therefore, it can be concluded that external interventions such as a pandemic can improve the relationship between the two variables to an appropriate level. The implications of these findings indicate that post-pandemic economic recovery needs to be directed towards strengthening labour-intensive sectors that absorb a large workforce. Policies to develop MSMEs, downstreaming, and improving skills after the pandemic could be the key to making East Java's economic growth more inclusive while reducing unemployment. Highlights: Tests Okun’s law consistency in East Java before and after COVID-19. Finds inverse correlation between growth and unemployment post-pandemic. Recommends post-pandemic recovery through labour-intensive and MSME sectors. Keywords: Economic Growth, Open Unemployment Rate, Okun's Curve, Pandemic, Pearson
