MULTIGROUP MODELING BASED PATH ANALYSIS ON PANEL DATA IN THE STUDY OF PRODUCTION PERFORMANCE IN SMALL AND MEDIUM INDUSTRIES IN MALANG
Get PDFThis study aims to determine the effect of the number of workers on production performance through the amount of production between small and medium industries in Malang City. This study applies multigroup modeling based on path analysis on panel data on variables that affect industrial production performance in Malang and the application of the Hypothesis of Linear Parameter Function in the multigroup model, which is the second group. This data source is secondary data from Malang Industrial data. The sample in this study is all data from small and medium industries in Malang City over several years. The results showed that the Hypothesis of Linear Parameter Function can be applied to the two-group model, that is, in a medium industry, where three significant paths are obtained. In the small industry, there are two considerable paths. Based on the coefficient of total determination, the data diversity can explain the model of 96.0%. At the same time, the remaining 4.0% is affected by other variables. The small and medium industry model shows that the number of workers significantly affects production. The effect is greater in medium industries, which is 0.935, compared to small industries, which is 0.737
IMPLEMENTATION OF LONG SHORT-TERM MEMORY (LSTM) IN FORECASTING THE NUMBER OF TRAIN PASSENGERS IN JAVA ISLAND
Get PDFFor certain Indonesians, trains are a particularly popular form of land transportation. Every year, during specific seasons, this mode of transportation consistently experiences a surge in passenger numbers. Due to this, it is necessary to make accurate predictions to make policies, such as whether additional carriages are needed. The selection of prediction methods will significantly impact policymaking. One of the methods currently being developed for prediction is related to machine learning. This study aims to implement a forecasting method using machine learning that can be used to predict time series data. The machine learning used in this study is the Long Short-Term Memory (LSTM) method. In this study, we used time series data on the number of train passengers. The data used is secondary data from the Statistics Indonesia (BPS). The data analysis process in this study uses Python software. The results of this analysis show that the LSTM model has a high level of accuracy in prediction, indicated by the mean squared error value of 2,941,137.156 and MAPE of 0.07%. Forecasts show a gradual increase in the number of passengers, starting from 32,381 people in the first month to 33,068 people in the third month. These results indicate that the LSTM model is thought to be effective in predicting changes in the number of train passengers, and further research is needed to verify this assumption

Get PDFThe study on the livelihood vulnerability of bamboo fish farmers in the Widuri River, Kasihan, Bantul, is essential for understanding the factors influencing their resilience to environmental risks. This research employs a quantitative method with a census approach, involving ten respondents who are bamboo fish farmers in the area. The collected data includes demographic profiles, education levels, farming experience, and aspects related to vulnerability, such as environmental pressure, adaptive capacity, and sensitivity. The analysis results show that the majority of respondents have a high school education, and most have less than one year of farming experience, indicating a significant interest among newcomers in fish farming activities. The farmers are vulnerable, with a Livelihood Vulnerability Index (LVI) score of 0.59. The pressures faced, such as floods and pollution, significantly impact their enterprises. An adaptive capacity score of 0.70 indicates a need for skill enhancement and income diversification. Additionally, their high dependence on fish farming as the primary source of income increases their vulnerability. Based on these findings, it is recommended that interventions be made through training in farming techniques, product diversification, and strengthening social networks to improve the adaptive capacity and resilience of farmers in facing existing environmental challenges. This research contributes significantly to developing risk mitigation strategies and the sustainability of fish farming enterprises in the region
