Abstract

The existence of Rumah Gadang is currently threatened due to the rarity of local/traditional materials and the cultural shifts within the Minangkabau people. Some of the surviving Rumah Gadang had undergone modernization in its form due to the use of modern materials such as concrete, zinc, etc. New questions arise whether the application of these modern materials can be considered sustainable for the Rumah Gadang. This study aims to compare the level of sustainability on the Rumah Gadang building material cycle before and after the modernization. This study conducted a case study of Rumah Gadang Padang Laweh, using a qualitative research approach with two data collection methods: observation and interviews. The collected data were then analyzed using the 'Green Feature' parameters, consisting of 15 assessment points. The study reveals that the building materials in the pre-modernized Rumah Gadang (25/30) show a higher sustainability value than the modernized ones (18/45).

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

Mosques, serving as places of worship for Muslims, require a high level of speech intelligibility to achieve the solemnity of worship. Due to rising urban temperatures, many mosques in tropical urban areas are transitioning from their previously open-designed condition, relying more on natural ventilation, to enclosed ones by leaning more on artificial ventilation. This study aims to understand the influence of space openness on speech intelligibility in mosques. Speech intelligibility measures how clear a voice is in a room and is measured by the speech transmission index (STI) method. This research utilizes the quantitative approach, integrating site observations, on-site measurements, and computational simulations. Focused on Masjid UI as the case study, the study simulates open and enclosed design configurations across three scenarios: full, half-full, and empty rooms. The results show that a mosque with an open design has a higher STI than a mosque with an enclosed design. However, the difference is insignificant due to several supporting factors in the existing condition, such as the square-shaped plan design with a pyramid dome, equal loudspeaker sound distribution, and a crowded worshippers’ condition.
