Abstract

The concept of productive green space has been mentioned in Al-Qur’an, which was revealed several centuries ago. However, Productive Facade (PF), a Vertical Greening System (VGS) method, has only recently been seen as a viable solution to provide crops and a cooler atmosphere in densely populated residential areas. The purpose of this article is to examine, from both scientific and Islamic perspectives, how shading and CO2 concentration reduction from PF can help cool the outdoor air, as well as the implications of this cooling mechanism for the development of a PF system as a secondary building skin that is more responsive to increasing urban temperatures. Literature reviews and experimental studies have been conducted to provide evidence and arguments from both scientific knowledge and Islamic perspectives. It was found that PF was able to provide an outdoor cooling effect. In addition, plant shade and CO2 uptake in PF are strongly correlated with air temperature. These findings are mentioned in the Qur'an and Hadiths as a basis for constructing an Islamic perspective.

Abstract

Various ambient air contaminants can spread into the indoor building through air transport. With the additional generation of contaminants from indoor activities, indoor air quality (IAQ) has the potential to be polluted. Indoor air pollution incidents can occur anytime, which is difficult to predict. Therefore, it is necessary to take action to improve IAQ as early as possible and sustainably. The solution to sustainable remediation is using plants to apply phylloremediation, which functions as leaves and leaf-associated microbial communities to reduce air contaminants. This study aims to provide new practical yet essential criteria for the sustainable operation of phylloremediation. This review is based on the latest results of a literature-based study. An analysis of the fundamental processes of plant life forms the basis for obtaining these criteria. The study emphasizes key criteria for phylloremediation encompassing the selecting plants with high transpiration and leaf-microbe synergy, and conducting maintenance by spraying water on leaves. These measures optimize efficiency and sustain the process for indoor air pollutant reduction. The final result summarises the new criteria for sustainable phylloremediation to maintain plant life. These essential criteria can be used for conducting experiments in empirical research, indoor design, and education for the community.

Abstract

Volatile organic compounds (VOCs) originating from construction materials and human activities present considerable health hazards in indoor settings. Phytoarchitecture provides a sustainable approach by incorporating vegetation into architectural design to effectively mitigate pollutants. This research seeks to define criteria for plant positioning according to photosynthetic pathways (C3, C4, and crassulacean acid metabolism (CAM)) to optimize VOC absorption. Employing a systematic literature review methodology, data on plant physiology, and leaf morphology were examined to establish a design framework. The findings suggest that the positioning of plants should be based on their stomatal opening cycles: CAM plants, which absorb carbon dioxide at night, are optimal for indoor bedrooms, whereas C3/C4 plants are more appropriate for daytime active areas and outdoor facades. Additionally, plants exhibiting narrow leaf profiles and elevated stomatal density exhibit enhanced VOC removal efficacy. It was determined that synchronizing architectural design with plant photosynthetic cycles establishes an efficient, passive air purification system that improves both indoor environmental quality (IEQ) and building aesthetics.

Abstract

Pencemaran air tanah oleh logam berat timbal (Pb) berdampak buruk bagi kesehatan manusia dan lingkungan. Logam berat Pb merupakan salah satu polutan yang disoroti karena bersifat toksik, persisten, dan bioakumulatif. Berbagai metode telah dikembangkan untuk remediasi air tanah tercemar Pb, tetapi sebagian besar memakan biaya yang mahal dan memerlukan waktu yang lama. Sebagai alternatif, teknologi Permeable Reactive Barrier (PRB) menawarkan pendekatan pasif in-situ yang efisien untuk mengurangi kadar logam berat dalam air. Implementasi PRB sudah beberapa kali digunakan dalam mereduksi berbagai kontaminan seperti Cr, Zn, Cu, Pb dan As. Hingga saat ini PRB terus dikembangkan untuk meningkatkan efektivitasnya dalam remediasi air tanah. Penelitian ini bertujuan mengevaluasi efektivitas PRB berbahan biochar tempurung kelapa dengan perekat semen dalam meremediasi air tanah berkadar Pb 100 mg/L dengan memvariasikan ketebalan (2 cm dan 4 cm). Reaktor beraliran vertikal dioperasikan selama 24 jam untuk mengamati performa penyisihan. Hasil menunjukkan bahwa PRB dengan ketebalan 2 cm menghasilkan efisiensi penyisihan tertinggi, yakni 99,9% dalam waktu detensi 6 jam, melalui mekanisme adsorpsi, presipitasi, dan interaksi ionik. Presipitasi Pb(OH)2 berperan penting pada pH basa yang dihasilkan oleh hidrasi semen, meskipun kondisi ini memerlukan pengaturan pH efluen sebelum dilepas ke lingkungan. Temuan ini memberikan dasar ilmiah untuk pengembangan PRB berbasis biochar-semen secara lebih luas, termasuk optimasi media, pengujian skala lapangan, dan penerapan pada sistem pengolahan air tercemar lainnya.
