Domestic wastewater generated from various types of buildings has been recognized to be different to some extent. This research aimed to know the quality, quantity, fluctuation of quality, and fluctuation of quantity of domestic wastewater discharged from office buildings. The composite samples were taken from two office buildings. The black water and gray water were taken from Building A with number of people 53 persons, and the mixed wastewater was taken both from Building A and Building B with number of people 900 persons. The fluctuation and quantity of wastewater were measured every hour from 7 am until 4 pm during the working time. The results showed that the quality of wastewater from office building contained 176 to 238 mg/L COD, 73.06 to 106.51 mg/L TN, and 3.66 to 7.70 mg/L TP with the average of C:N:P ratio was 100:42:2.56. Quantity of wastewater discharged from office buildings were from 39.61 to 49.93 liter/person/day. COD concentration changed significantly during the working time with mean ± standard (252.5±89). The quantity of wastewater varied over time and the peak discharge for black water and gray water were 2.85 litter/person/hour and 3.74 liter/person/hour, which occurred during the beginning of working time and the praying time of muslim Indonesian culture. It suggests that the domestic wastewater from office buildings has specific characteristics and it contains high concentration of nutrient that is required appropriate advanced technology for treating this kind of wastewater.

Industri farmasi menghasilkan senyawa aktif farmasi yang bersifat persisten dan berbahaya bagi lingkungan dan makhluk hidup jika memasuki badan air. Pengolahan air limbah secara konvensional belum mampu menyisihkan senyawa aktif farmasi dengan baik. Review artikel ini dilakukan karena semakin meningkatnya populasi penduduk di Indonesia maka semakin meningkat pula produksi dan penggunaan produk obat-obatan dari industri farmasi. Pelepasan kandungan mikropolutan obat-obatan yang bersifat persisten ke dalam saluran pembuangan air adalah sekitar ng ~ µg/L secara terus menerus mengalir ke lingkungan dan air limbah akan membahayakan kesehatan makhluk hidup dan lingkungan. Senyawa aktif farmasi yang bersifat persisten terdiri dari analgesik dan antiinflamasi, antibiotik, antidiabetik, antihipertensi, beta-blocker, diuretik, lipid regulator, obat psikiatri, reseptor antagonis, hormon, beta-agonis, antineoplastik, produk topikal, antiseptik, agen kontras dan agen anti kanker. Artikel ini mereview mekanisme biosorpsi beberapa biosorben yang digunakan dalam menurunkan senyawa POPs dalam pengolahan limbah cair industri farmasi yang terdiri dari biomassa dari limbah pertanian dan limbah industri. Mekanisme biosorpsi senyawa POPs dalam pengolahan limbah cair industri farmasi meliputi interaksi elektrostatik, interaksi ikatan π-π elektron donor akseptor, ikatan hidrogen, pengisian pori, interaksi hidrofobik, atraksi dipol permanen, pertukaran ion, interaksi asam basa Lewis, gaya Van der Waals, dan fotodegradasi. Arah pengembangan penelitian berikutnya yaitu pengembangan biosorben dari limbah yang dimodifikasi kimia untuk mengoptimalkan kapasitas biosorpsi senyawa POPs dalam pengolahan limbah cair industri farmasi.

This research aimed to find the effect of initial concentration and hydraulic retention time (HRT) on modified septic tank (MST) performance in treating wastewater from an office building. The synthetic wastewater used had an average COD:TN:TP ratio of 84:28:1, adjusted to office building wastewater characteristics. The experiment was executed under steady conditions using three variations of HRT (12, 24, and 36 hours) and different initial concentrations of COD (106, 252 and 432 mg COD/L), TN (35, 85 and 146 mg N/L) and TP (1.26, 3 and 5.14 mg P/L). The result showed that the MST removed 82% to 92% of COD, 41% to 60% of TN, 45% to 61% of NH4, and 39% to 55% of TP. The maximum removal was achieved at 36 h of HRT, COD:TN (3:1), and COD:TP (84:1). One-way ANOVA showed that the initial concentration and HRT had significant effects on the performance of MST (p < 0.05). This suggests that appropriate control of the initial concentration and HRT in the MST can effectively remove organics and nutrients from office building wastewater.

Universal access to water, sanitation and hygiene (WASH) is a basic human right that reflects well-being. However, disparities in access to WASH persist in Indonesia, influenced by economic factors, education and sanitation behaviours. In urban areas, urban poverty exacerbates the gap in access to WASH, with the urban poor vulnerable to inadequate sanitation due to economic and knowledge constraints. In Kecamatan Bandung Wetan, which is located in the middle of Bandung city, this condition is still found, where low-income groups are vulnerable to the fulfilment of proper sanitation. The sanitation index is a tool to evaluate the sanitation system in a community. The sanitation index was analysed using exploratory factor analysis. The variables that make up the index are based on the 5 pillars of Community-Led Total Sanitation (CLTS). The results of the analysis show that the sanitation index in Kecamatan Bandung Wetan is built by the factors of clean water use, household welfare, low prevalence of environmental diseases, faecal user interface, and final disposal of household waste, with the highest sanitation index value found in Kelurahan Citarum.

The 2030 Sustainable Development Goals (SDGs), based on human rights and equality, urge developing countries, including Indonesia, to accelerate development efforts, particularly in the area of sanitation. In line with the SDGs, Indonesia has set a national medium-term development plan (RPJMN) for 2020-2024 that aims to achieve 90% access to adequate sanitation, with 15% designated as safe sanitation and 0% open defecation. The safe sanitation targets are driving the development of septage treatment plants (IPLT) in various cities and districts in Indonesia. Indonesian IPLTs are transitioning from traditional to semi-mechanical or fully mechanical systems. The Kalimulya IPLT uses a semi-mechanical approach, combining conventional wastewater treatment with mechanical sludge treatment. This study evaluates the IPLT Kalimulya using a technology audit approach based on the UNESCAP (1989) methodology to identify factors affecting the optimisation of IPLT management. The assessment of technoware, humanware, infoware and orgaware revealed an overall Technology Capability Classification (TCC) score of 0.55 for IPLT Kalimulya, indicating a 'good' category with semi-modern technology. The infoware component achieved the highest score, reflecting strong performance, while the humanware and technoware components were rated at a standard level.

The difficulty of sustainable development is hampered by water scarcity and increased water demands, particularly in urban areas. Domestic wastewater discharges contaminate surface water bodies, such as the Citarum River. These difficulties, which disproportionately affect low-income populations, contribute to health consequences like diarrhoea and stunting. The Reinvented Toilet Project, a community-based sanitation programme, was put into place in Pasirluyu Village, Bandung, to combat water pollution. In order to lower water demand and sewage generation, it includes water reuse, reusing processed wastewater for other applications. This study assesses Pasirluyu Village infrastructure users' attitudes towards social water reuse. Surveys gathered data on demographics, views on water recycling, and information about sanitary facilities. Spearman correlation tests and descriptive analysis were carried out. The outcomes show that infrastructure users have a positive impression of water reuse. However, some people are hesitant to use reclaimed water for activities that require close personal touch. The relationship between public acceptability of water reuse for flushing toilets and acceptance for other purposes raises the possibility of a cascading expansion of water reuse practises. Keywords: community-based infrastructure, households, water reuse, water reuse aceptance
