Abstract

The prolonged conflict between the Free Aceh Movement (GAM) and the Government of the Republic of Indonesia has resulted in social disruption, collective trauma, and the weakening of community social structures. Although a peace agreement was reached through the 2005 Helsinki Memorandum of Understanding, the greatest post-conflict challenge lies in rebuilding trust, solidarity, and social harmony. An interesting phenomenon is the success of Acehnese society in achieving social stability through internal strengths, particularly a strong Islamic religious approach and deeply rooted local culture. This article aims to analyze the contribution of religious and local cultural approaches in fostering post-conflict social harmony in Aceh. This study is qualitative in nature, using a descriptive-interpretative approach. Data collection techniques included in-depth interviews, document analysis, and surveys. Key informants consisted of religious leaders (ulama), traditional leaders, former GAM combatants, women leaders, youth, and village officials located in former conflict-affected regions such as Pidie, North Aceh, and Bireuen. Data analysis employed a thematic approach through data reduction, categorization, interpretation of findings, and inductive conclusion drawing. The findings show that religious approaches, through the active roles of ulama, religious gatherings (majelis taklim), and Islamic boarding schools (pesantren), have been effective in restoring faith-based values and community social ethics. Meanwhile, local cultural elements such as peusijuek (traditional blessing rituals), gampong deliberations, and customary village institutions have served as effective means of social reconciliation, strengthening community ties and resolving horizontal conflicts. The synergy between religious values and local wisdom has formed a strong social system for maintaining peace and preventing future conflicts. In conclusion, religious and local cultural approaches have proven to be fundamental pillars in creating sustainable social harmony in post-conflict Aceh. This model can serve as a strategic reference for other conflict-affected regions seeking to build peace through local potential.

Abstract

This research aims to prepare natural coagulants from Angsana leaves (Pterocarpus indicus willd) for Palm Oil Mill Effluent (POME) treatment, especially reducing main variables such as TSS, COD, and pH. The amounts of 100 mesh Angsana powder (5, 10, 15, and 20 grams) were extracted using NaCl solvent with concentrations of 0.25 M and 0.5 M, respectively. The extract (200 mL) were added to 500 mL of POME and stirred (180 rpm) for 30 minutes. The concentrations of TSS, COD, and pH in POME were analyzed. Results showed that the coagulation-flocculation process using Angsana leaves powder was able to reduce COD by 55.79% at a coagulant dose of 5 g/L with 0.25 M NaCl solvent and TSS by 99.75% at a dose of 20 g/L with 0.25 M NaCl solvent. However, treatment using Angsana leaves extract was not able to reduce COD to the predetermined quality standard limits while the TSS value met the quality standard. Therefore, POME treatment still requires further processing.

Abstract

Mercury (Hg) is a highly toxic heavy metal with no biological benefits, posing significant environmental and health risks upon exposure. This study investigates the adsorption characteristics of chicken eggshell-derived adsorbents for the removal of Hg from aqueous solutions. The adsorbent preparation involved washing, drying, calcination, and KOH activation. Results indicated that the 170-mesh size adsorbent exhibited the highest adsorption efficiency, achieving a 99.70% removal rate of Hg. adsorption capacity tests revealed values ranging from 79,90 to 88,90 mg/g, conforming to the Indonesian National Standard (SNI) for activated carbon. Functional group analysis using Fourier-Transform Infrared Spectroscopy (FT-IR) identified a significant increase in aldehyde and ketone groups post-activation. The adsorption process reached equilibrium within 90 minutes, with optimal removal efficiency observed at an initial Hg concentration of 3,0 mg/L. These findings suggest that chicken eggshell-based adsorbents are a cost-effective and efficient solution for mitigating Hg contamination in wastewater, offering a sustainable alternative to conventional methods.
