Abstract

Evaluasi Kinerja Waduk Resapan UI dan Potensi Pemanfaatannya sebagai Sumber Air Baku. Waduk resapan Universitas Indonesia (UI) telah dibangun sejak 5 tahun yang lalu. Namun kegiatan monitoring dan evaluasinya sangat minim dilakukan. Tujuan dari studi ini adalah untuk mengetahui laju resapan, dan untuk mengevaluasi kondisi kuantitas dan kualitas air waduk resapan selama musim kemarau dan penghujan. Pengukuran kedalaman muka air, intensitas curah hujan dan penguapan dilakukan untuk menentukan ketersediaan air, laju resapan, dan imbangan air waduk. Sejumlah air permukaan diambil dari waduk resapan dan sungai di tiga titik sampling untuk mengetahui kondisi kualitas air eksisting. Hasil studi menunjukkan tidak ada perbedaan yang signifikan antara laju resapan musim kemarau (3,2 mm/hari) dan musim penghujan (6,1 mm/hari). Imbangan air waduk resapan menunjukkan nilai yang berlimpah. Berbagai parameter fisik dan kimia air (kekeruhan, warna, TDS, pH, dan Cl) mempunyai konsentrasi di bawah standar baku mutu. Temuan dari studi ini antara lain bahwa air permukaan waduk masih layak untuk diimbuhkan ke dalam lapis aquifer sehingga mendukung keberlanjutan gerakan konservasi air, dan ketersediaannya sangat berpotensi untuk dikembangkan sebagai sumber air baku tambahan bagi kebutuhan air domestik di lingkungan Kampus UI Depok.

Abstract

UI GreenMetric was established before the initiative of the Sustainable Development Goals and other ranking to encourage universities in achieving sustainable development through their early awareness of environmental management on campus. In 2019, Times Higher Education launched a new ranking, namely the THE Impact Rankings, that assessed Sustainability progress implementation on campus. In this paper, we evaluate the impact of the consistency of university that have been participated in UI GreenMetric World University Rankings (UIGWUR) since 2010 to 2021. We evaluate 36 universities on the correlation between good performance in UIGWUR to the THE Impact ranking performed by 2019-2021. The results reveal that UI GreenMetric as an assessment tool, helped those universities in terms of shaping university readiness to achieve sustainable development. Those universities compete through annual reporting and the provided evidence of their progress on UI GreenMetric. Moreover, some universities have a high commitment to become sustainable campus through participating in sustainability-related rankings to monitor their progress regardless of the ranking results.

Abstract

Laundry businesses in Indonesia have high economic development opportunities. However, laundry wastewater in Indonesia does not yet have a good environmental culture and regulations for service users. Constructed wetland can be used as a sustainable biological processing technology, uses low energy, and does not require high costs to process laundry wastewater. The aim of this research is to analyze the ability of horizontal sub-surface flow constructed wetlands in a batch system with different numbers of aquatic bamboo plants (Equisetum hyemale) in degrading chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) in laundry wastewater. The research results showed that reactor 2 HSSF CW with a total of 200 E. hyemale plants produced higher removal efficiency compared to reactor 1 HSSF CW with a total of 120 E. hyemale plants where reactor 2 produced COD and BOD5 removal efficiency respectively. amounted to 88.22% and 90.30% while reactor 1 produced COD and BOD5 removal efficiencies of 86.04% and 88.10% respectively. Based on these results, reactor 1 and reactor 2 horizontal sub-surface flow constructed wetlands with E. hyemale plants produced effective performance in reducing COD and BOD5 concentrations in laundry wastewater.

Abstract

This research aims to analyze the efficiency of processing liquid waste from the laundry industry using the Free Water Surface Constructed Wetland (FWS) system with Azolla microphylla plants. The research method used is experimental research by manipulating independent variables and controlling other relevant variables, as well as observing the effect on the dependent variable. Laundry waste samples were taken from Berkah Laundry, Puri Gading, Bekasi. The results showed that the biomass of Azolla microphylla plants increased significantly from day 0 to day 12, with a growth rate between 0.0289 – 0.0477 grams/day and plant density between 185.19 ind/m2 – 277.78 ind/m2. The influent BOD concentration of laundry liquid waste during the acclimatization stage ranged from 5.89 – 10.54 mg/L, while the effluent BOD ranged from 4.35 – 6.98 mg/L, with the highest efficiency reaching 33.8%. The constructed wetland system with Azolla microphylla plants has proven to be effective in reducing pollutant content in liquid waste, with a BOD removal efficiency of 11.1% - 17.7% and COD of 14.5% - 39%. The conclusion of this research is that the use of artificial wetlands with Azolla microphylla plants can be an effective and environmentally friendly alternative solution for processing liquid waste from the laundry industry. The implications of this research show the potential for applying constructed wetland technology in the clothes washing industry to reduce the negative impact of waste on the environment.
