Thermodynamic Analysis of Activated Walnut Husks in the Adsorption of Iron (III) Ions from Aqueous Solutions: An Assessment of Feasibility and Sustainability: Analisis Termodinamika Sekam Kenari Teraktivasi dalam Adsorpsi Ion Besi (III) dari Larutan Berair: Penilaian Kelayakan dan Keberlanjutan
No full textThis is the case of global water contamination phenomena for which an economic solution is necessary. Walnut husks have proved to be cost-effective alternatives in iron removal from aqueous solutions. A biosorption study of Fe(III) from aqueous solution using walnut husk powder pointed out that sorption capacity increased as the sorption temperature rose in accordance with various isotherm models. Thermodynamic study says that this is an endothermic process. That would then vindicate this study as showing the potential walnut husks, hence, can be used to efficiently remove heavy metals, which include iron, from water. Under the optimum condition, the maximum percentage removal was 93.28%. Observations during the experiment of the adsorbent showed high degrees of removal; at 25°C, pH=2, concentration = 100ppm, and weight=0.5g, the least percentage removal is up to 89.244 percent. Data shows that the regression coefficients give superiority to the Langmuir isotherm over the Freundlich model. Equilibrium data for the process were tested with the constants of Langmuir, and the constants of Freundlich were calculated. Further, thermodynamic experiments were carried out to ascertain the values of ΔS, ΔH, and ΔG for the adsorption of iron under optimized experimental conditions.

Pragmatics Study of Speech Act of Apology Between Men and Women: Comparative Study: Kajian Pragmatik Tindak Tutur Permintaan Maaf Antara Pria dan Wanita: Studi Komparatif
No full textGeneral Background: Apology strategies are essential in communication, influencing interpersonal relationships and social interactions. Understanding how men and women employ these strategies differently can provide insights into gender-based linguistic variations. Specific Background: Olshtain and Cohen (1983) identified five categories of apologetic techniques: Apology, Repair Offer, Account Explanation, Acceptance of Responsibility, and Forbearance Promise. While previous studies have explored apology strategies, limited research has examined their application in real-life contexts, particularly in Padang. Knowledge Gap: Despite extensive research on gender and language, there remains a lack of empirical studies comparing the specific techniques men and women use when apologizing and how these choices are shaped by social and cultural factors. Aims: This study aims to analyze the similarities and differences in the apology strategies of men and women, identifying patterns in their linguistic choices and behavioral tendencies. Results: Findings reveal that both genders employ all five apology strategies, with direct apologies being the most commonly used and forbearance promises being the least. Men favor explanation-based apologies, while women prefer offering repair. These differences stem from distinct communication styles—women emphasize emotions and solidarity, whereas men focus on logic and status. Novelty: Unlike prior studies, this research uses a purposive sampling method to analyze real-life expressions of regret in a natural setting. It highlights the impact of gendered communication styles on apology choices, offering new perspectives on pragmatic language use in social interactions. Implications: Understanding gender-based apology strategies can enhance cross-gender communication and reduce misunderstandings. These findings are valuable for interpersonal communication training, language teaching, and cross-cultural studies, contributing to the broader field of sociolinguistics and pragmatics.
