Abstract

Rice production was a crucial component in maintaining national food security, particularly in Sumatra, which was known as one of Indonesia's rice granaries. This study aimed to analyze the determinant factors affecting rice production in Sumatra using a multiple linear regression approach. Secondary data utilized in this research included 224 observations from eight provinces in Sumatra, covering the period from 1993 to 2020. The independent variables analyzed included Year, Harvest Area, Rainfall, Humidity, and Average Temperature, with Rice Production as the dependent variable. The resulting multiple linear regression model was expressed by the following equation: Rice Production (Y) = −63.442.498,904 + 32.535,572 × Year + 4,622 × Harvest Area + 46,106 × Rainfall – 3.993,403 × Humidity – 62.701,579 × Average Temperature. Data processing was performed using SPSS software, which included normality testing, linearity testing, simultaneous F-test, and coefficient of determination analysis. The normality test results indicated that the residuals of the model were normally distributed (Asymp. Sig. = 0.227 > 0.05). The linearity test showed a significant linear relationship between the independent variables and rice production, with no deviation from linearity. The regression model demonstrated a coefficient of determination (R²) value of 0.877, meaning that 87.7% of the variation in rice production could be explained simultaneously by these five variables. Furthermore, the F-test results indicated that the regression model was statistically significant (Sig. = 0.000). These findings suggested that the five variables significantly influenced rice production and could serve as a basis for strategic decision-making in the agricultural sector. The resulting model also held the potential as a predictive tool in planning policies to enhance rice production in the future.

Abstract

The development of digital technology has driven many businesses to utilize e-commerce systems in marketing their products. This research focuses on the design and implementation of a website-based e-commerce system to support the sale of antique items at Renvin Antique Gallery. The aim is to reach a wider market and enhance the online shopping experience for customers. A Research and Development (R&D) approach is adopted with stages including needs analysis, system design, implementation, testing, and evaluation. The research subjects involve the store owner and customers, with data collection techniques through interviews, observations, and questionnaire distribution. The research instrument utilizes the WebQual 4.0 model, which has been tested for validity and reliability, with data analysis using descriptive statistical methods aided by SPSS. The end result of this research is a web-based e-commerce system equipped with product catalog, shopping cart, checkout process, and PayPal payment integration features. Based on testing with WebQual 4.0, the system scores an average of 4.28 or 85.6%, which falls into the highly feasible category. The research concludes that the developed e-commerce system is able to meet user needs and provide a good online shopping experience. Suggestions for further development include regular optimization and updating of website content, more active promotion and marketing strategies, as well as periodic evaluations based on user feedback.
