Media Framing Analysis of Pertamina’s Official Press Conference on the Adulterated Fuel Issue During Pre-Crisis, Crisis, and Post-Crisis Phases
No full textIn early 2025, the transition from Pertalite to Pertamax coincided with a corruption case in Pertamina’s oil governance, triggering a national reputation crisis. The media played a crucial role in shaping public perception of Pertamina’s crisis communication response. This study analyzes how detikFinance and Kompas.com frame Pertamina’s official press conference across the pre-crisis, crisis, and post-crisis phases. Using a descriptive qualitative approach and Pan & Kosicki’s framing model (syntactic, script, thematic, and rhetorical structures), six news articles published between February 25 and March 8, 2025, were examined in depth. The findings show a clear contrast in framing. detikFinance emphasizes technical clarification, institutional diction, and explanations of internal processes and supervision. Kompas.com highlights legislative pressure, public concerns, and rhetorical cues that strengthen critical narratives and allegations of fraud. These distinctions reflect each outlet’s editorial orientation and specific audience segmentation. The study confirms that media framing is not neutral; it shapes crisis perception through fact selection, narrative structure, and stylistic choices. The findings enrich crisis communication and media framing studies and underscore the importance of transparent, strategic, and empathetic public relations to maintain stronger public trust during complex crises
Social interaction and spatial values toward sustainability and resilience in Islamic urban pilgrimage settlements
No full textIslamic urban pilgrimage kampungs in Southeast Asia face increasing pressures from modernization and environmental risk, yet religious spatial values continue to structure social interaction and everyday resilience. Empirical studies highlight the role of mosque- and waqf-based practices in sustaining cohesion, neighborhood and kinship networks in preparedness, and shared alleys and markets as arenas of socio-economic negotiation. However, comparative and longitudinal evidence remains limited, inclusivity across gender and ethnic groups is uneven, and few studies operationalize spatial-religious values into resilience metrics. This article synthesizes theoretical and empirical scholarship on the intersections of social interaction, religious significance, sustainability, and resilience in pilgrimage kampungs, while proposing a replicable agenda for research and practice. A Systematic Literature Review was conducted using query transformation, criteria-based screening, and citation chaining, yielding five thematic clusters. Critical synthesis is organized through the EGAP Matrix (Evidence-Gap-Action-Priority) and an MCDA-inspired, score-free priority map. Findings emphasize socially embedded resilience frameworks and adaptive communal networks, while revealing major gaps in methodological integration and measurement tools. The study advances actionable directions, including multi-site longitudinal designs, gender-sensitive co-production models, and spatial-value indicator toolkits, to inform urban planning and community-based heritage governance in Islamic pilgrimage kampungs
Regenerative livable space in geotechnical engineering: A sustainable approach to urban development
No full textThe increasing global demand for urban space, combined with the impacts of climate change, has led to a need for more sustainable and regenerative approaches in civil and geotechnical engineering. Regenerative livable space focuses on creating urban environments that not only minimize environmental harm but also restore ecological functions. In geotechnical engineering, this concept translates into practices that integrate soil-structure interaction, ground improvement techniques, and eco-engineering to support resilient, safe, and ecologically balanced infrastructure. This study conducted a literature review of eight previous studies on five fundamental aspects of geotechnical engineering to determine its role in creating sustainable urban development. The results show that geotechnical engineering has contributed to addressing potential environmental challenges such as landslide risk, soil erosion, and slope stability. Geotechnical engineering has also played a crucial role in creating resilient and ecologically integrated cities through various disaster-oriented planning initiatives
The effect of geometric variable design configuration on the acoustic quality of the auditorium (systematic literature review)
No full textPoor acoustics may impede communication and user experience, and yet traditional design approaches often ignore the varying acoustic needs. The present paper systematically reviews pertinent literature to assess how flexible geometric design options (e.g., adjustable surfaces, modular panels, or dynamic surfaces) affect relevant acoustic parameters (reverberation time, clarity, and sound distribution) in comparison with conventional empty auditorium designs. By following PRISMA Protocol (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) applied strictly to ensure transparency and reproducibility of the research process, 25 experimental and simulation studies from Scopus, Science Direct, Journal of The Acoustical Society of America, Sage, MDPI, and others were analyzed. Results indicate that proper geometric design can improve acoustics quality variation, particularly in multipurpose applications; however, implementation must consider cost and technical complexity. Therefore, conclusions and recommendations serve as an evidence-based guideline for architects and acoustical engineers involved in designing adaptive performance spaces in terms of real-time adjustment technologies and smart materials. On the other hand, new standards for acoustic evaluation of dynamic designs should also be created
The relationship between the cooling effect of parks and the urban heat island effect in Jakarta and Bandung
No full textCities around the world are experiencing the Urban Heat Island phenomenon, due to increasing urbanization and human activity, as well as environmental degradation characterized by a lack of green space. With the remaining green open spaces in urban areas, what contribution can they make to address this phenomenon? According to several journals, green open spaces can provide cooling effects through trees, and when combined with blue spaces such as water, the results can be optimized. Therefore, the objective of this study is to examine whether there is a connection between the cooling effects of parks in two cities (Jakarta and Bandung) and surface land temperatures, one of the ways to observe the Urban Heat Island phenomenon. The research method used is quantitative descriptive, with several stages of analysis, including LST analysis and the cooling effect of parks. The results of this study indicate a connection between the cooling aspects of parks, divided into two character: large parks (area, intensity, gradient) and small parks (efficiency) in relation to surface temperature in the districts where the parks are located
Valorisation of Sugarcane Bagasse Ash from Malawian Sugar Mills for Zeolite Precursor Synthesis: A Compositional and Thermal Analysis
No full textThis study investigates the chemical suitability of sugarcane bagasse ash (SBA) sourced from three Malawian sugar production facilities of Nchalo, Dwangwa, and Salima, for use as a precursor in zeolite synthesis. SBA samples were thermally treated at 500°C, 600°C, and 800°C, followed by elemental characterisation using X-ray fluorescence spectroscopy. Emphasis was placed on the quantification of silicon dioxide (SiO2) and aluminium oxide (Al2O3), both of which serve as essential precursors in hydrothermal zeolite formation. Across all samples and temperatures, silica concentrations remained consistently high, with Dwangwa ash at 600°C recording the highest level at 76.22%. Alumina content exhibited greater variability, with Nchalo ash at 800°C yielding the most enriched profile at 15.97%. Although silica levels met the criteria for zeolite production, measured alumina concentrations were insufficient to achieve the required Si/Al molar ratio for direct synthesis. As a corrective measure, the study incorporated secondary aluminium sources, such as recycled metallic waste, to meet stoichiometric thresholds and enable effective framework formation. Variations in oxide content were traced to both calcination-induced phase transitions and regional differences in soil composition, which influence mineral uptake during cultivation. Statistical analysis confirmed that source location materially affects ash composition, with clay-dominant soils in the Nchalo region contributing to higher Al2O3 content. The results establish SBA as a viable source of silica and a partial source of alumina for engineered zeolite synthesis, contingent on precise process control and composition adjustment. This approach promotes the reuse of agro-industrial residues and supports the production of cost-effective water treatment materials using regionally available resources
The climatic evolution of the Inaouen River Basin in Morocco: Rainfall variability and its connection to the North Atlantic Oscillation
No full textThe Inaouene basin is considered among the basins most subject to rainfall variability, marked by sometimes exceptional dry periods (as low as 252.2 mm) and rainy periods (up to 1129 mm), as recorded at the Taza station, due to the variability of atmospheric factors that control atmospheric circulation, in particular the North Atlantic Oscillation.This study therefore aims to know the impact of this oscillation on the variability of rainfall by calculating the standardized precipitation index and the correlation coefficient. The study revealed that the dominance of the positive phase of the North Atlantic Oscillation since the end of the seventies had a major role in the absence of moist air masses towards Morocco, which caused the stability of climatic conditions of drought in the study area, with the presence of some extreme rainfall events, in which the evidence of the North Atlantic Oscillation is weak
Long-term monitoring of surface water dynamics using remote sensing data: A case study of Al Wahda dam, Morocco
No full textAl Wahda Dam, located in northern Morocco, is one of the country's most strategic hydraulic infrastructures, with a storage capacity exceeding 3 billion cubic meters. It was constructed in 1997 to ensure agricultural irrigation in the Gharb plain, provide flood protection, and regulate hydrological flow in the region. However, the performance of this structure has been increasingly affected by rainfall deficits and the growing demand for irrigation water. In addition, rising temperatures have increased evaporation losses, particularly during the summer, thereby reducing the effective storage capacity. This study aims to monitor the spatiotemporal evolution of the Al Wahda dam using the NDWI index derived from remote sensing data. It also seeks to highlight the impact of rainfall variability on the dam by calculating the SPI. The findings suggest that during wet years, the water surface area increases significantly (110 km2 in 1998), whereas during dry years, a marked contraction of this surface is observed (72 km2 in 2016). The statistically significant correlation (p-value < 0.05) between the dam's water surface area and the SPI-12 indicates the influence of climatic conditions on its dynamics
In vitro shoot induction of BesNO H 382 tobacco using benzyl amino purine
No full textBesuki Na Oogst (BesNO) H 382 tobacco is a superior commodity intended for export as a raw material for cigar production in the international market from Jember Indonesia. The development of its seed development through tissue culture has advantages such as the ability to produce healthy and uniform seeds, pathogen-free and regardless of the season. This study aimed to determine the optimal concentration of benzyl amino purine (BAP) for in vitro shoot induction. The research using a Completely Randomized Design with four levels of BAP concentration ranging from 0 to 3 ppm. The findings showed that BAP concentrations between 1 and 3 ppm significantly influenced shoot induction of BesNO H 382 tobacco. Among these treatments, 3 ppm BAP was identified as the most effective concentration, with shoot emergence observed at 8.40 days, an explant weight of 4.44 g, and an average of 30 shoots per explant at 56 days after inoculation. These results provide valuable insights into the optimization of plant growth regulators from the Cytokinin group for optimal shoot induction of BesNO H382 tobacco which is still rarely reported with a new modification of the explant sterilization technique
