Abstract

Environmental sanitation refers to an environment's health status, including housing, sewage disposal, clean water supply, waste management, and other factors. Sustainable Development Goals 6 (SDG 6) ensures people access proper environmental sanitation. Based on the monitoring and evaluation results of Community-Based Total Sanitation (STBM) in 2022, it was found that 100% of open defecation had been stopped for Pillar 1 of STBM. This study aims to identify the factors that influence the success of implementing Open Defecation Free (ODF) programs in Depok City. There are two stages in this study to determine the priority factors that influence the success of the Implementation of Open Defecation Free in Depok City using the AHP method. The first stage is identifying the factor, which is based on previous literature that has been done, as these factors are considered to have a significant influence and role in the success of program implementation. This study's factors were related to the contextual, psychosocial, and technological aspects, and The second stage involves data collection through a questionnaire distributed to 35 respondents who were analyzed using the AHP method. The results of this study are the main influential factors, such as personal background, knowledge of the importance of community sanitation, and ownership/maintenance of physical products, can lead to the effective implementation of ODF programs. However, it is essential to note that the success of ODF programs may vary depending on the specific context in which they are implemented. Thus a tailored approach may be necessary.

Abstract

The increase in waste generation and water use in urban areas may lead to local flooding that is dangerous for health if it is not appropriately managed by waste and water systems in urban infrastructure. Sponge City is a concept that utilizes Green Infrastructures (GIs) to manage waste and water systems while still maintaining open and public spaces function. This study aims to review the waste and water infrastructure systems in Depok, Indonesia which are compared with Gainesville in the United States, America and Cardiff, United Kingdom, to give recommendations for preventing flooding in urban areas. Analysis is done by comparison of data based on factors that affect GI implementation, such as (1) management system, (2) policy context, and (3) key organizations or stakeholders. Data collected are digital statistics of the current flooding disasters, water management systems, and waste management systems are collected using web scraping of the latest news and information regarding the said topics. This study concluded three possible GI implementations in a hierarchy. The GI implementation in Depok focuses on the making of programs and management systems which involve citizen participation that prioritize the development of biopores at the household level. Gainesville focuses on Gainesville Department of Public Works which controls both waste and water management, namely through the prioritization of single-use plastic bans throughout Gainesville. In Cardiff, it focuses on the attempt of the Wales Government and Cardiff Council to make an integrated development strategy that prioritizes holistic surface water management combined with a waste disposal system. This study can open possibilities of GI implementations that reflect the urban areas characteristic in preventing local flooding by managing waste and water systems.

Abstract

This paper evaluates natural ventilation effectiveness in one fully dependent Air Conditioned-Educational Building in Depok to recommend potential passive cooling approaches toward user thermal comfort. This study involves building surveys to measure the temperature and humidity of three selected classrooms, A, B, and C, with varying configurations and capacities. Airflow simulation using Computational Fluid Dynamics (CFD) is done under two conditions: open and closed doors. A set of parameters, which are room configuration, type of window, and ventilation strategy, are set to evaluate natural ventilation aspects. The site survey indicates that only one classroom with an area of 92 sqm facing to the southside is classified as efficiently warm (Room A). The simulation demonstrates that cross-ventilation only occurs when the door is opened. The parameters indicating shape, dimension, type, and area of natural ventilation matter, show that the building’s natural ventilation is ineffective in providing thermal comfort. This study recommends that the building’s natural ventilation be placed according to the direction of the airflow, adding vertical fin elements, and increasing the openings by more than 5% area from the floor area.

Abstract

Shading devices are essential for reducing solar radiation and cooling loads in buildings located in tropical climates. In the Jakarta region, the highest solar factor is observed on west- and east-facing facades, followed by north- and south-facing orientations. National building policy in Indonesia encourages facades to face north–south to reduce solar heat gain. This study explores horizontal static and dynamic shading devices on north-facing facades and evaluates their impact on cooling load reduction and daylight performance. The methodology includes calculating and simulating energy use intensity (EUI) using EnergyPlus and conducting illuminance analysis using Radiance and Grasshopper. Key parameters considered in the shading design include sun position, illuminance levels, and EUI. The results show that static shading devices with a fixed tilt angle of 20° and a depth of 1.2 m reduce the cooling load by 15.82% while ensuring that at least 30% of the workspace floor area receives an average illuminance of 300 lux throughout the year. Meanwhile, dynamic shading devices with adjustable tilt angles ranging from 10° to 40°, following the sun’s position, reduce the cooling load by 15.75%–18.83%. This configuration consistently ensures that at least 30% of the workspace floor area achieves 300 lux of illuminance each month. These findings provide a practical reference for the design of north-facing shading devices in tropical climates, balancing thermal performance and daylight availability.

Abstract

Educational buildings in Depok City typically have deep classroom plans, which pose a challenge in achieving good uniformity of lighting distribution throughout the room. Therefore, this study aims to investigate the integration of daylight and artificial lighting to achieve lighting uniformity, especially in classrooms of educational buildings in Depok City. This paper simulated the combinations of Light Shelves (LS), horizontal blind curtains, and artificial lighting dimming systems through Dialux software to explore and discuss the illumination distribution of daylight in the classroom. The combinations were arranged in 7 different strategies and were carried out in average sky conditions. The strategy simulation results show that lighting uniformity is optimally achieved in strategy 3 with 0.74 lux and strategy 7 with 0.72 lux. These results prove an increase in the uniformity of daylight in the classroom by 0.49 lux with LS and 0.58 lux with horizontal blinds but still requires artificial lighting with 50% dimming. Keywords: Dimming; Horizontal blind curtain; Lighting uniformity; Light shelves.

Abstract

This study examines the relationship between the green-based school with students’ environmental attitudes and behavior. Sustainable development has become the solution and commitment to save the earth from destruction due to human behavior. Environmental education plays an important role in creating an environmentally literate society. Adiwiyata School, an official form of environmental education, is one of the efforts to increase sustainable development through education as a way to improve student's environmental attitude and behavior. The research design used multiple case studies utilizing the observation method and questionnaire distribution to Adiwiyata and non-Adiwiyata schools. A New Ecological Paradigm (NEP) scale and a General Ecological Behavior (GEB) scale are used to measure student's environmental attitudes and behavior change. As a result, the green-based school creates influences in student's environmental attitudes (9.3%) and environmental behavior (12.3%).

Abstract

This study aims to reduce heat gain and minimise cooling energy through building envelope material as a passive design intervention strategy to achieve thermal comfort. Integrated Learning Building in the Faculty of Engineering, Universitas Indonesia, is used as a case study due to its air conditioning setting. First, the material characteristic of the building envelope is calculated using the Overall Thermal Transmission Value (OTTV) calculation to determine heat gain and the EDGE (Excellence in Design for Greater Efficiencies), a software to estimate cooling energy consumption. Then, a passive design intervention strategy is performed by adding insulation (polyester, bagasse, and recycled textile and paper) and substituting window glazing (reflective, PVB laminated, and Clear IGU Low-E). The results show that the combination of recycled textile and paper insulation and clear IGU Low-E window glazing has an OTTV value of 24.89 W/m2 which is lower than the standard in Indonesia (35 W/m2). Meanwhile, the cooling energy usage shows an energy consumption of 1.14% lower, but it did not achieve the 5% reduction target. Therefore, further intervention on other parts of the building envelope, such as the roof and floor, should be observed to achieve higher energy-saving potential.

Abstract

The construction sector has the potential to improve its sustainability through the application of circular economy principles, which primarily emphasize two cycles: replacing conventional materials with biological alternatives and enhancing the recycling of technical materials. This study aims to analyze the current facade design of the Engineering Center (EC) Building at Universitas Indonesia (UI) as an initial study to explore Alternative Design (AD) with a hybrid approach of biological and technical cycles. This study’s method mixes Building Circularity Calculation (BCC) and incorporates Material Passport (MP) and Material Flow Analysis (MFA). The study emphasized that utilizing mycelium brick (predominantly a biological material, comprising 63%) has outstanding potential to achieve building circularity implementation in the EC Building facade. The finding highlights a hybrid design strategy, incorporating a significant proportion of biological materials, could be a promising pathway for implementing building circularity in the EC Building. Biological materials are generally causing less environmental impact compared to technical materials, yet further mitigation strategies are required due to their shorter lifespan. To build based on these findings, exploring a wider range of building components and other possible variants of hybrid designs are recommended in future research.
