This research delves into the urgent requirement for innovative agricultural methodologies amid growing concerns over sustainable development and food security. By employing machine learning strategies, particularly focusing on non-parametric learning algorithms, we explore the assessment of soil suitability for agricultural use under conditions of drought stress. Through the detailed examination of varied datasets, which include parameters like soil toxicity, terrain characteristics, and quality scores, our study offers new insights into the complexities of predicting soil suitability for crops. Our findings underline the effectiveness of various machine learning models, with the decision tree approach standing out for its accuracy, despite the need for comprehensive data gathering. Moreover, the research emphasizes the promise of merging machine learning techniques with conventional practices in soil science, paving the way for novel contributions to agricultural studies and practical implementations.

The food and beverage sector played a big part in contributing to the economic growth in Malaysia hence there was a major increase in the numbers of restaurants opening up for businesses. This study therefore examines factors with the aims of ensuring a sustainable development in full-service restaurants in West Malaysia. The results of this study have made a substantial contribution to restaurant owner’s’ comprehension of the fundamental components that underlie customer satisfaction and loyalty. By examining the moderating effect of the customer’s gender in full-service restaurants in West Malaysia, the objective of this study was to ascertain the relationships between the three variables (quality of the food served at the restaurant, service quality, and environment), as well as the degree to which each attribute was able to relate to diner satisfaction. The underpinning theory for this study was the Theory of Planned Behavior (TPB). Quantitative methods according to descriptive research and convenience sample strategy were utilized in this cross-sectional study. Questionnaires were distributed to 264 respondents through various online platforms such as WhatsApp, Telegram, Facebook, and email. Data collection was evaluated using the Statistical Program for Social Sciences (SPSS) version 27. In order to examine the connection between the three factors and diner’s satisfaction, various tests such as the multiple regression analysis, One-way ANOVA and Beta Coefficient test were carried out. The findings gave current restaurant owners and potential restaurant owners an overview of the different attributes influencing diner’s satisfaction at full-service restaurants in West Malaysia and also the extent of the moderating effect of diner’s gender had on each attribute. The outcome of this paper is expected to provide a sustainable growth in this industry.

This study aims to elucidate the impact of marketing investment dimensions (MTS, MTOE, ROMI) on profitability indicators (ROA, ROE, GPM, OPM) and sustainable growth indicators (SGR, ARG) for service companies. The study population consisted of 135 service companies listed on the Amman Stock Exchange. A purposive sample of 55 companies was selected from this population. Financial reports and statements from 2018–2022 for these companies were analyzed to achieve the study objectives, employing appropriate statistical methods like multiple regression to test hypotheses. Previous literature shows conflicting results regarding the relationship between marketing investment dimensions and profitability/sustainable growth. Some studies found positive impacts, while others did not. This study contributes to this debate by providing statistical evidence. The results show that higher MTS, MTOE, and ROMI have a positive impact on SGR, OPM and ROA but a negative impact on GPM, ARG, and ROE. This underscores that marketing investments should be viewed in conjunction with overall operating expenses. Companies that control other expenses and increase the marketing investment proportion of total operating expenses may achieve better financial performance. Marketing investment metrics can serve as useful diagnostics and measures of effectiveness for improving marketing profitability, financial performance, and growth. In summary, this study statistically demonstrates the nuanced impacts of marketing investments on service company profitability and sustainable growth indicators. The results emphasize analyzing marketing spends in context of broader expenses and overall company financial health.
