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

AbstrakGedung dan komplek perguruan tinggi hingga kini masih mengelola sampahnya dengan menggunakan sistem kumpul, angkut dan buang. Namun, dengan merebaknya wabah COVID-19 yang lalu ikut juga menghentikan kegiatan perkuliahan pada gedung-gedung perguruan tinggi. Namun sejak wabah COVID-19 mulai dapat dikendalikan, seluruh kegiatan kembali berjalan dengan skenario ‘new normal’. Perubahan pola penggunaan gedung selama masa ‘new normal’ berpotensi juga mempengaruhi timbulan dan komposisi sampah yang dihasilkan. Untuk itu, penelitian ini bertujuan untuk mengkaji perbandingan jumlah timbulan dan komposisi sampah pada gedung kuliah saat sebelum pandemi COVID-19 dan pada era ‘new normal’. Metode penelitian menggunakan mixed methods, dengan studi kasus menggunakan gedung S yang merupakan gedung perkuliahan umum yang belokasi di FTUI, Kota Depok. Penelitian ini menunjukkan bahwa jumlah mahasiswa yang hadir pada era ‘new normal’ hanya 57,6% dari mahasiswa yang terdaftar, namun timbulan sampah yang dihasilkan sebesar 81,44 kg/hari, atau sebesar 0,04 kg/hari/mahasiswa atau dua kali lebih banyak dari sebelum pandemi COVID-19, dengan komposisi sampah 61,40% adalah sisa makanan dan kemasan makanan dan 38,60% adalah sampah plastik. Hal tersebut karena adanya perubahan gaya hidup sebagian besar mahasiswa. Bertambahnya timbulan sampah saat ‘new normal’, membuat pengelolaan sampah pada Gedung S perlu disesuaikan kembali dengan komposisi sampah yang dihasilkan, dengan menerapkan konsep 3R.Kata kunci: Pengolahan sampah, gedung kuliah, era ‘new normal’AbstractBuildings and university complexes still manage their waste using a collection, transport and disposal system. The recent outbreak of the COVID-19 outbreak also stopped lecture activities in university buildings. However, since the COVID-19 outbreak began to be controlled, all activities have resumed with a 'new normal' scenario. The amount and makeup of waste generated are impacted by this change. This research aims to examine the comparison of the amount of waste generation and composition in lecture buildings before the COVID-19 pandemic and in the 'new normal' era. The research uses mixed methods, with a case study using S Building, a public lecture building located at FTUI, Depok. This research shows that the number of students attending in the 'new normal' era was only 57.6% of registered students, but the waste generated was 81.44 kg/day, or 0.04 kg/day/student, twice more than before the COVID-19 pandemic, with a waste composition of 61.40% being food scraps and food packaging and 38.60% being plastic waste. This is due to changes in the lifestyle of most students. This increase in waste generation means that waste management in S Building needs to be readjusted to the composition of the waste produced, by applying the 3R concept.Keywords: waste management, college buildings, the ‘new normal’ era

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.
