Abstract

In Indonesia, the waste sector is responsible for 10.59% (130,188.21 GgCO2e) of global warming emissions, one of which is from campus domestic wastewater due to the lack of wastewater treatment plants. Only 0.2% of the 6,472 campuses have treatment systems, such as Universitas Negeri Malang (UM) use a fabricated anaerobic baffled reactor (FABR) for wastewater treatment plants for its green campus initiatives, yet available only for several buildings and do not treat all wastewater generated from the campus activity. However, Life Cycle Assessment (LCA) of ABR system has not been widely studied, especially when it uses in treating of the campus wastewater. This study aims to conduct the LCA of the laboratory -scale ABR system in the campus wastewater treatment with gate-to-gate scope using Simapro 9.1.11 and the CML-IA Baseline. Three scenarios were tested: untreated wastewater, ABR equipped with peristaltic pumps, ABR without pumps. The results indicated that ABR treatment had a significantly lower environmental impact than untreated wastewater, with the greatest reduction in global warming potential (1.51E-08 to 4.98E-11), followed by eutrophication and photochemical oxidation. This study is limited to the ABR system, future research could expand to include the full lifecycle, from material collection to final results.

Abstract

Semakin banyaknya pembangunan di Indonesia termasuk fasilitas industri perikanan memberikan dampak pada kondisi lingkungan. Fasilitas industri perikanan di Kota Malang saat ini belum memiliki sistem pengolahan air limbah. Faktanya air limbah budidaya ikan yang dihasilkan dapat mencemari air permukaan. Polutan (Nitrogen dan Fosfor) yang terdapat pada air limbah budidaya ikan baik hasil dari sisa metabolisme maupun sisa pakan ikan dapat menyebabkan eutrofikasi. Penelitian ini bertujuan untuk menganalisa reduksi konsentrasi polutan (Nitrogen dan Fosfor) pada air limbah budidaya perikanan dengan menggunakan tanaman air Lemna minor menggunakan sistem Free-Water Surface Flow Constructed Wetlands (FWS CW). FWS CW yang digunakan dalam penelitian ini mempunyai dimensi tinggi 0,4 m, panjang 2 m dan lebar 1 m. Debit air limbah budidaya ikan yang dialirkan menggunakan dua macam Hydraulic Retention Time (HRT), yaitu 14 jam dan 7 jam. FWS CW dengan HRT 14 jam dengan debit inlet 15,14 mL/s dapat menurunkan konsentrasi amonium, nitrat dan fosfat dengan tingkat efisiensi 50,09%; 28,11%; dan 72,37%. Sedangkan FWS CW dengan HRT 7 jam dan debit inlet 30,28 mL/s dapat menurunkan konsentrasi amonium, nitrat dan fosfat dengan tingkat efisiensi 38,93%; 23,91%; dan 88,28%. Dapat disimpulkan bahwa FWS CW dengan HRT 14 jam lebih efisien untuk mereduksi nitrogen, sedangkan FWS CW dengan HRT 7 jam lebih efisien untuk mereduksi fosfor.

Abstract

The drinking water distribution network in Istana Dieng residence is categorized as an isolated network because it does not connect with the other water distribution networks provided by the Malang Water Company (Perusahaan Daerah Air Minum, PDAM). For this reason, the residual chlorine of the isolated distribution network needs to be monitored regularly. Aim: This study aims to observe residual chlorine distribution patterns and investigate the effect of distribution distance, pH, and temperature on residual chlorine concentration in the water distribution network. Methodology and Results: Analytical survey method with a cross-sectional approach was used in this study. The field survey results and the water analysis were inputted into the ArcGIS 10.6 software to generate an Isoconcentration map. Correlation and regression analysis were conducted using SPSS 16.0. Conclusion, significance and impact of study: The results showed that 65% of the residual chlorine concentration in the drinking water distribution network Istana Dieng residence did not meet the quality standard (<0.2 mg/l). Twenty-six sample points showed a value of 0.1 mg/l, which was caused by the pipe's physical condition and the use of wells connected to the PDAM network. There was a significant correlation between distance and residual chlorine concentration. The significant correlation between pH and residual chlorine concentration showed a value of -0.690. The correlation between temperature and residual chlorine concentration was -0.633. It was proven that the lower the residual chlorine concentration, the higher the pH and temperature values in the distribution network.

Abstract

Groundwater is a natural resource used by humans to fulfil their living needs which should meet the Republik Indonesia Minister of Health Regulation No. 2/2023. Aim: This research aims to contribute to solve these challenges and meet the clean water quality standard. Methodology and Results: The groundwater sample was taken from the deep well of Al-Hikmah Mosque, Universitas Negeri Malang (UM). It was indicated to contain Fe and Mn, as evidenced by its yellowish colour when left undisturbed for some time. A laboratory-scale experiment was conducted for the deep well treatment and analysis. The treatment system consists of aeration, sedimentation, and filtration. The filtration unit comprises several natural media such as gravel, silica sand, zeolite, and activated charcoal. This experiment used detention times of 120 and 240 minutes as dependent variables. Conclusion, significance, and impact study: The results showed that detention times of 120 and 240 min have efficiency on turbidity reduction of 92.86% and 98.69%, Total Dissolved Solids (TDS) of 10.42% and 14.47%, Fe of 23.01%, Mn of 62.39% and 94.70%, and for CaCO3 of 2.98% and 11.17%, respectively. The research findings demonstrated that a detention time of 240 min generated water quality that met the Minister of Health No. 2/2023 standards. Detention times of 120 minutes and 240 minutes led to significant differences in water quality concerning temperature and CaCO3. The filtration system with a detention time of 240 minutes can be considered as an alternative groundwater treatment solution for the deep well of Al-Hikmah Mosque, Universitas Negeri Malang.

Abstract

Introduction: Dengue fever is a top ten global health threat according to the World Health Organisation (WHO). Indonesia, especially Malang City has 560 dengue haemorrhagic fever cases in 2022 with Sukun Sub-district having the highest number of 159 cases. Dengue haemorrhagic fever vector control carried out by the government is currently 3M (drain, cover, and recycle) where it is still conventional. Whereas generally now there have been many studies on dengue vector control innovations, one of which is the Ae. aegypti with Wolbachia. The programme has been implemented in Yogyakarta and resulted in a decrease in dengue fever cases. The purpose of this study was to analyse the stigma and acceptance of the community in Malang City towards the Wolbachia-infected Ae. aegypti with Wolbachia programme in controlling dengue haemorrhagic fever vector. Methods: The method used was cross-sectional using questionnaires to 100 communities in Sukun Sub-district, Malang City with non-dense and dense populations. Results: The results showed that 87.5% of densely populated communities were aware of the programme, while only 5% of non-densely populated communities were aware of the programme. Based on the questionnaire results, it is known that the majority of community concerns about the programme between non-dense and dense communities are the same, namely the cost and health risks. However, after distributing the comic "What is Ae. aegypti with Wolbachia?" the community's acceptance towards the programme was found to be majority accepting. The community also hoped that there would be a socialisation activity from the relevant government for the next step of implementation. Conclusion: This study concluded that the community had a positive stigma and acceptance towards the Wolbachia-infected Ae. aegypti with Wolbachia programme if implemented in their area.
