Abstract

Indoor air pollution is dangerous for human health because almost 90% of human activity occurs indoors. An important factor when assessing indoor air quality is the concentration of carbon dioxide (CO2). Even at very low concentrations, it can have a marked effect on the health of those in it. The purpose of this study was to review the ability of moss used as a living wall to absorb CO2 and study its potential application in improving indoor air quality. In addition, this research will also identify challenges that may be faced in implementing living moss walls. This study used the true experimental method with a pretest and posttest control group observation design. The study was conducted by comparing CO2 levels from 2 white cigarette smoke with and without living moss wall in a prototype room made of glass with dimensions of 40 cm x 40 cm and 55 cm high.The research results show that the use of living moss wall as a solution to overcome indoor air pollution, especially CO2, cannot be separated from several obstacles that must be faced in its implementation. Living moss wall has a relatively low CO2 reduction efficiency value by using blumei’s moss (Macromitrium blumei). The use of a living moss wall must also pay attention to the suitability of the environment where it is installed so that the living moss wall can function properly.Keywords: Living moss wall, carbon dioxide (CO2), indoor air pollution  ABSTRAK Pencemaran udara dalam ruangan berbahaya bagi kesehatan manusia karena hampir 90% aktivitas manusia terjadi di dalam ruangan.

Abstract

In the era of industry and technology in Indonesia, environmental problems due to waste are problems that require wise handling. Fly Ash (FA) waste from PLTU activities and Spent Bleaching Earth (SBE) waste resulting from the palm oil production process are very abundant, thus polluting the environment. Indonesia is currently prioritizing physical infrastructure development, which aims to improve connectivity and encourage economic growth in every sector. The development process that occurs increases the use of concrete. Concrete has a tremendous impact on the environment because most of its composition is cement. The use of cement in the manufacture of concrete results in the emission of large amounts of CO2 gas into the atmosphere, which causes an increase in global warming. The use of concrete can have a lower environmental impact if the use of cement is reduced as much as possible by adding a mixture of FA and SBE wastes. This research will utilize FA and SBE waste in the manufacture of normal concrete production weights and aim to determine the optimal composition of FA and SBE waste that is economically and environmentally feasible. The results of the research by applying FA and SBE substitutions show that FA is better than bleaching earth in the resulting compressive strength. The optimal composition of FA as a substitute for cement to achieve the quality of the planned concrete is 15%, while the composition of SBE as a substitute for cement is 10%. Keywords: concrete, Fly Ash (FA), Spent bleaching earth (SBE), concrete compressive strength  ABSTRAK In the era of industry and technology in Indonesia, environmental problems due to waste are problems that require wise handling.

Abstract

This research aims to analyze the potential of utilizing rainwater at the Rectorate Building of Universitas Andalas by examining both its quantity and quality, and by proposing an appropriate rainwater harvesting system (RWHS) design. The quantitative assessment employed 20 years (2003–2022) of maximum daily rainfall data collected from the Batu Busuak Station as the primary reference, supported by three additional stations. Based on a planned roof catchment area of 53.25 m², the calculated runoff discharge is 0.00013 m³/s, indicating that rainwater has considerable potential to serve as an alternative water source. The quality of rainwater shows that parameters such as temperature, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity, iron (Fe), and manganese (Mn) comply with the water quality standards set by the Regulation of the Minister of Health No. 2 of 2023 and Government Regulation No. 22 of 2021. However, the rainwater exhibits an acidic pH (4.14 ± 0.53) and elevated Escherichia coli levels (34.03 ± 41.86 MPN/100 mL), which exceed permissible limits and require treatment prior to use. The selection of suitable treatment technologies was conducted using the Simple Additive Weighting (SAW) method. The analysis showed that sand–calcite filtration system combined with chlorination as the most effective option, achieving a score of 95.90. This system is recommended for non-potable applications, specifically for toilet flushing, with an estimated water demand of 4.93 m³ and a ground tank capacity of 5 m³. The total estimated cost of the proposed RWHS is approximately IDR 26,258,000. Keyword: rainwater, rainwater quality, Log Pearson Type III, Simple Additive Weighting, Rainwater Harvesting System

Abstract

The increasing volume of waste generation in Bungurasih Village, Sidoarjo Regency, has created an urgent need for adequate waste management facilities. The existing Temporary Waste Storage (TPS) is suboptimal, equipped only with four simple transport carts and an incinerator lacking an emission control system. This study aims to evaluate the current condition of the TPS, analyze waste composition, density, and generation rate, and redesign the facility into a Reduce, Reuse, Recycle Waste Processing Site (TPS3R). The research employed a literature review and qualitative descriptive approach, supported by primary data collection through eight consecutive days of sampling. The results indicate that the average waste density reaches 428.84 kg/m³, with a daily waste generation of 6,359.70 kg. The redesign includes the construction of a TPS3R on an area of 809 m², consisting of sorting zones, organic waste processing, composting, storage, and supporting facilities. The estimated total cost for the TPS3R construction is IDR 1,769,480,000. This result is expected to serve as a planning reference for community-based integrated waste management systems in rural areas.

Abstract

This study examines the resilience variables of urban Drinking Water Supply Systems (WSS) in responding to floods, with a focus on West Sumatra Province, Indonesia, using the Fuzzy Delphi Method (FDM). The study identifies three main resilience properties: robustness, recovery, and learning, within a temporal framework. Thirteen sub-properties and 41 indicators were validated using FDM by 10 experts in fields relevant to the research topic. As a result, 12 sub-properties were accepted by expert consensus, while one sub-property, namely governmental situation awareness, was rejected because all three of its indicators failed to meet the validation criteria. A total of 33 out of 41 indicators were considered significant, relevant, and useful by the expert panel. Furthermore, the findings emphasize the critical role of the governmental dimension in determining the resilience level of SPAM in West Sumatra Province. These results will serve as a guide for policymakers in prioritizing resilience-based decisions to mitigate flood threats.
