Indonesia is known as a country rich in local culture and traditions that are passed down from generation to generation. One of the traditions that is still preserved by the Bugis-Makassar people is Mappanre Temme, which is a procession of Qur'an khatam which is an important part of the traditional wedding series. This research aims to examine the symbolic meaning and cultural values in the Mappanre Temme tradition and its relevance in the life of modern society. The method used is a literature study with a qualitative descriptive approach. The results of the study show that this tradition contains religious, educational, social, and moral values. Apart from being a symbol of the spiritual readiness of the bride-to-be, this tradition is also a medium for the preservation of Islamic values and local culture. However, modernization also affects the meaning of this tradition, so sustainable preservation efforts are needed.

This study investigates the role of acquisition premiums in mergers and acquisitions (M&A) and their impact on shareholder wealth, focusing on five major Indian deals in pharmaceuticals, retail, banking, steel, and renewable energy sectors. Potential synergies often justify acquisition premiums ranging from approximately 15% to 40% above target companies’ market values. However, market responses suggest that such premiums may not consistently result in value creation for acquiring firms' shareholders. Empirical findings reveal mixed outcomes: Sun Pharma’s acquisition of Ranbaxy led to a 9.8% share price increase within five days, while Tata Steel’s high-premium acquisition of Bhushan Steel saw only a 1.7% gain. In contrast, deals like Reliance–Future Retail and Tata Power–Welspun Power showed minimal or negative returns, despite sizable premiums. These patterns indicate that premium size alone is not a reliable predictor of post-deal shareholder wealth creation. The study concludes that M&A success depends more on strategic fit, market timing, and sectoral dynamics than on the premium offered. This analysis contributes to the broader M&A discourse by offering evidence-based insights into how premium valuations can either maximise or dilute shareholder value, aiding investors, corporate strategists, and policy analysts in deal assessment

This study aims to analyze the influence of economic factors on the estimated demand for Pertalite fuel at PT Pertamina (Persero) during the 2020–2024 period. The background of this research is based on the increasing consumption of Pertalite in Indonesia in line with fluctuations in fuel prices, economic growth, and population growth. The originality of this research lies in the development of an empirical model to estimate the demand for Pertalite using macroeconomic variables, including Pertalite prices, public income (GDP per capita), population, and substitute fuel prices. This study uses a quantitative approach with descriptive and verifiable methods, where data is analyzed using multiple linear regression with the help of SPSS software. The classical assumption test showed that the model met the criteria of normality and was free of multicollinearity, heteroscedasticity, and autocorrelation, making it worthy of analysis. The regression results showed that the price of Pertalite had a significant negative effect on estimated demand, GDP per capita and population had a significant positive effect, while the price of substituted fuel had a positive but insignificant effect. A determination coefficient (R²) of 0.847 indicates that the model explains most of the variation in Pertalite demand estimates. These findings confirm that demand for Pertalite in Indonesia is inelastic because it remains high despite price fluctuations. The results of this study are expected to be the basis for the government and PT Pertamina (Persero) in formulating a strategy for pricing, subsidies, and energy distribution that is more adaptive to national economic dynamics.

The Influence of Work Flexibility and Organizational Support on Employee Work-Life Balance at PT Industri Kapal Indonesia (Persero) Makassar City. This study was conducted to examine the extent to which work flexibility and organizational support can affect the level of employee work-life balance at PT Industri Kapal Indonesia (Persero) Makassar City. The focus of the research is directed to identify which variables have the greatest contribution to improving work-life balance, as well as to understand how the relationship between these two variables shapes employee perceptions and experiences in balancing work demands with personal needs. The research approach used is a quantitative method with an associative design. Data collection was carried out through the distribution of questionnaires to 132 employees of PT Industri Kapal Indonesia (Persero). The analysis techniques used include instrument tests, classical assumption tests, multiple linear regression, and partial (t-test) and simultaneous (F test) tests to assess the influence of independent variables (work flexibility and organizational support) on dependent variables (work life balance). The results of the analysis show that work flexibility has a positive and significant influence on employees' work-life balance. Organizational support is also proven to have a significant influence on employees' ability to achieve work-life balance. In addition, the results of simultaneous tests show that the two variables together contribute strongly in improving work-life balance. These findings indicate that a combination of flexible policies and organizational support can strengthen employee well-being, reduce work pressure, and encourage a more adaptive work environment

Penelitian ini bertujuan untuk mengetahui pengaruh lingkungan kerja terhadap produktivitas kerja melalui motivasi kerja sebagai variabel intervening pada tenaga pendidik SMK Penerbangan Techno Terapan Makassar. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Populasi dalam penelitian ini adalah seluruh tenaga pendidik SMK Penerbangan Techno Terapan Makassar sebanyak 63 responden dengan teknik sampling jenuh. Teknik pengumpulan data dilakukan melalui observasi, kuesioner, dan studi literatur. Analisis data menggunakan Structural Equation Modeling–Partial Least Square (SEM-PLS) dengan bantuan aplikasi SmartPLS versi 4.0. Hasil penelitian menunjukkan bahwa lingkungan kerja berpengaruh positif dan signifikan terhadap produktivitas kerja dengan nilai p-value sebesar 0,011 dan koefisien pengaruh sebesar 1,071. Lingkungan kerja juga berpengaruh positif dan signifikan terhadap motivasi kerja dengan nilai p-value sebesar 0,000 dan koefisien pengaruh sebesar 0,969. Namun, motivasi kerja tidak berpengaruh signifikan terhadap produktivitas kerja dengan nilai p-value sebesar 0,091 dan koefisien pengaruh sebesar -0,449. Selain itu, motivasi kerja tidak mampu memediasi pengaruh lingkungan kerja terhadap produktivitas kerja karena diperoleh nilai p value sebesar 0,312.

This study aims to examine the influence of the learning environment and school discipline on students' learning achievement, mediated by learning motivation, at MI Al Hidayah Mamasa. A quantitative approach with a correlational design was employed. The study population consisted of all 120 students at MI Al Hidayah Mamasa, with a sample of 92 students determined using Slovin's formula at a 5% margin of error. Data were collected using a Likert-scale questionnaire. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4 software. The results indicate that the learning environment has a positive and significant effect on students' learning motivation (β = 0.401, p = 0.000) and on students' learning achievement (β = 0.726, p = 0.000)—serving as the most dominant factor in the model; school discipline has a positive and significant effect on students' learning motivation (β = 0.228, p = 0.001) and on students' learning achievement (β = 0.343, p = 0.000); and learning motivation has a positive and significant effect on students' learning achievement (β = 0.442, p = 0.000). Furthermore, learning motivation significantly mediates the effect of the learning environment on learning achievement (indirect effect = 0.321, p = 0.000) and significantly mediates the effect of school discipline on learning achievement (indirect effect = 0.151, p = 0.002). The model yielded R² values of 0.765 for learning motivation and 0.680 for students' learning achievement. These findings confirm that improving the quality of the learning environment and consistently implementing school discipline are strategic measures to optimize students' academic achievement by strengthening their learning motivation.
