“…Krisis air bersih di daerah perkotaan menjadi isu yang sangat krusial seiring dengan berjalannya waktu (Inkani et al, 2020). Hal ini disebabkan oleh peningkatan populasi manusia, urbanisasi, polusi air, dan peningkatan taraf hidup tanpa diimbangi dengan peningkatan ketersediaan air (Molinos-Senante & Donoso, 2016).…”

The declining supply of freshwater is the challenge in modern times and rainwater harvesting (RWH) is an alternative to solve the problem. This paper studies the potency of water saving at Rusunawa Muara Baru (Muara Baru Public Flat) by daily analysis instead of monthly or yearly analysis in order to take into account the rainwater tank’s capacity. The research is performed by projecting the daily rainfall during January 2019 – August 2020 onto the daily water use of the public flat occupants. Because the daily water consumption data does not exist, the paper sets the daily water consumption as per the issued standard and validates it with the real data. The water conservation rate of the RWH is determined by having the factual water usage volume reduced by the stored rainwater volume in daily timescale. The analysis presents 7,55 % water conservation during the research period. and 6,57 % by assuming average annual rainfall for Jakarta region. The daily analysis in this case does not produce different outcome compared to monthly or yearly analysis because the rainwater tank has large volume. However, daily analysis will be relevant when the storage capacity is small.. Abstrak Ketersediaan air bersih yang semakin sedikit merupakan tantangan di dunia modern dan sistem pemanenan air hujan (SPAH) merupakan salah satu alternatif solusi. Artikel ini meneliti potensi penghematan air di Rusunawa Muara Baru dengan analisis harian, bukan dengan analisis bulanan atau tahunan untuk mempertimbangkan kapasitas tampungan tangki air hujan. Penelitian ini dilakukan dengan memproyeksikan hujan pada Januari 2019 – Agustus 2020 ke kebutuhan air harian dari penghuni rusunawa. Karena data penggunaan air harian tidak ada, penelitian ini mengambil angka berdasarkan standar yang berlaku dan divalidasi dengan kebutuhan air faktual. Lalu, tingkat penghematan air oleh SPAH dihitung dengan mengurangi volume pemakaian air harian dengan volume air hujan yang ditampung secara harian. Hasil analisis menunjukkan bahwa SPAH menghemat air sebesar 7,55 % sepanjang periode penelitian dan 6,57 % dengan curah hujan tahunan rata-rata di wilayah Jakarta. Analisis harian di kasus ini tidak menghasilkan hasil yang berbeda dengan analisis bulanan atau tahunan karena besarnya volume tangki air hujan. Namun, analisis harian akan diperlukan bila kapasitas tampungan bervolume kecil.

At a time of growing threats to global freshwater availability, urban water supply is becoming increasingly challenging, affecting water security for urban populations. Alternative water sources, technologies, and supply methods are employed to complement dwindling continental water sources and guarantee the human right to water. However, the related research reports that such solutions can exacerbate inequalities and jeopardise water security for the most vulnerable groups. There is therefore a need to delve into household dynamics and practices in order to detect the drawbacks of the water supply solutions implemented as part of sociotechnical transitions or climate change adaptation measures. The present article contributes by proposing a flexible framework for evaluating household water dynamics and everyday experiences based on the urban metabolism metaphor and enriched with feminist political ecology and critical literature on water security. The framework builds upon typical water balance accounts and is supplemented with information on (a) the source, price, continuity and pressure of all types of water consumed domestically; (b) the consumer’s relationship with water, that is, whether people trust each water source, whether they accept its organoleptic characteristics (flavor, odor, and transparency), and whether they fear that consuming water may have negative health impacts; and (c) the actions that people employ to improve tap water quality for drinking, thus allowing the calculation of indirect costs and impacts associated with inadequate water quality. Results indicate that lower-income households metabolise water of lower quality and do so more slowly than high-income households. Furthermore, the actions they take to improve water quality involve more effort, higher monetary costs, additional energy consumption, and greater health impacts compared to higher-income groups.
