Abstract

An increase in population often leads to a surge in the volume of wastewater that must be treated. Wastewater treatment plants (WWTPs) play a role in reducing environmental pollution caused by discharging wastewater into bodies of water. However, WWTPs are also a major source of greenhouse gas emissions, including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). This study aims to evaluate the carbon footprint generated by treating 1 m³ of domestic wastewater at the IPAL X unit. The Life Cycle Assessment (LCA) approach with gate-to-gate system limitations was used. Data processing was done with the help of the OpenLCA software program. According to the LCA analysis results, the Moving Bed Biofilm Reactor (MBBR), Filtration, and Equalization Tank units produces the highest carbon footprint. The sourced of carbon footprint from electricity consumption and degrading organic compounds through biological treatment in MBBR unit.

Abstract

The high level of non-revenue water (NRW) poses a significant challenge in managing the water supply system of Perumdam Kota Magelang, especially in the Perum Korpri District Metered Area (DMA), which recorded a 56.16% loss from a total annual input volume of 171,770 m³. This study aims to evaluate the technical aspects of water loss and formulate NRW reduction strategies based on Internet of Things (IoT) technology. The methods include the collection of primary and secondary data, water balance analysis using WB-Easy Calc, and hydraulic network simulation through EPANET 2.2. The evaluation focuses on network pressure, consumption fluctuations, and meter accuracy. The results indicate that high pressure during minimum demand hours significantly contributes to physical leakage. Proposed mitigation strategies include the implementation of step-test, installation of Pressure Reducing Valves (PRVs), calibration of district inlet meter, and the application of an IoT-based SCADA system for real-time monitoring. The integration of these technologies is expected to enhance operational efficiency and extend the lifespan of the water distribution network.

Abstract

Pelaksanaan Layanan Lumpur Tinja Terjadwal masih memiliki tantangan tersendiri. Hal ini disebabkan oleh kondisi pengelolaan sampah di Kota Kendari. Tujuan dari penelitian ini adalah untuk mengetahui kondisi eksisting, pengetahuan, dan minat masyarakat terhadap layanan lumpur tinja. Data kualitatif dikumpulkan dari wawancara dengan pemangku kepentingan, survei kuesioner sampel acak, kemudian dianalisis menggunakan perangkat lunak WEKA 3.9.8, evaluasi teknis dan manajemen menggunakan diagram alir tinja, dan Penyelenggaraan Layanan Sanitasi Kota (PPKS) adalah metode yang digunakan untuk mengumpulkan data dan merumuskan kesimpulan secara komprehensif. Hasil penelitian menunjukkan bahwa rendahnya cakupan layanan (0,004%) dari total penduduk terjadi karena kewajiban berlangganan program hanya dilakukan dalam lingkup Organisasi Pemerintah Daerah, sehingga masyarakat tidak mendapatkan informasi yang jelas terkait program ini. Kesiapan pelaksanaan layanan sejauh ini hanya 63%. Analisis kuesioner oleh WEKA 3.9.8 menunjukkan kurangnya sosialisasi menjadi isu utama rendahnya cakupan layanan. 82,6% tidak mengetahui tentang program L2T2, dan hanya 17,4% yang mengetahuinya. 74,1% masyarakat belum menerima informasi mengenai layanan lumpur tinja, meskipun 72,1% masyarakat tertarik dengan program ini. Diagram Alir Lumpur Tinja menunjukkan bahwa hanya 6% layanan yang termasuk dalam kategori aman, sejalan dengan Penyediaan Layanan Sanitasi Kota, yang menunjukkan bahwa peningkatan sistem pendataan, inklusi layanan, dan penguatan kerangka kelembagaan sangat mendesak untuk mencapai keberlanjutan program ini.

Abstract

Revegetation efforts on former limestone mine sites offer potential for climate change mitigation through biological CO2 absorption. However, the extreme conditions at these mining locations necessitate the validation of planting media to ensure the success of initial plant propagation. This study aimed to compare the effectiveness of commercial growth medium and limestone soil sourced from the Berkah Sari Bumi Rembang mine site as the initiation media for the early growth of revegetation plants, specifically utilizing maize (Zea mays L.) and groundnut (Arachis hypogaea L.) as test species. Generative propagation was conducted in a greenhouse for 30 days, involving physical observation and plant height measurement every 7 days. The primary parameter observed was plant height, assessed using the relative growth rate (RGR). The results showed a significant difference in growth rates between the plants grown in the two media. In the commercial growth medium, all maize and groundnut plants survived until the end of the propagation period with significant growth; the highest plant height was recorded by the BISI-2 maize variety at 51.4 cm on Day 30, with the best growth rate of 0.11 cm/week during the 14-21day period. Conversely, the limestone soil exhibited very slow growth. Most plants died before the propagation period was complete, and the only surviving plant was the BISI-2 maize variety, reaching a maximum height of only 5.5 cm on Day 14. The commercial growth medium is the recommended choice for propagation due to its sufficient nutrient content and good water retention ability, making it ideal for preparing optimal plants before they are transferred for the main study on limestone soil.

Abstract

Secondary sludge generated from aerobic biological treatment in beverage industry wastewater plants is produced in large quantities and contains essential nutrients that offer potential for beneficial reuse. This study evaluates the utilization of non-hazardous secondary sludge as planting media by characterizing sludge properties and assessing its performance when mixed with three different type of soils (Soil A, B, and C) and amendments. Sludge cake was blended with each soil type as a control, and further treatments incorporated (a) dolomite, (b) Trichoderma sp., and (c) a combination of both amendments. The mixtures were monitored over two weeks for C/N ratio and N, P, K content, following compost quality parameters. Results indicate that most mixtures achieved a C/N ratio ≥10 after two weeks, except for Soil A with and without dolomite. All treatments exceeded the minimum compost nutrient requirements set by SNI 19-7030-2004. The application of Trichoderma sp. produced the highest nutrient enhancement, with nitrogen reaching 1.8% and phosphorus reaching 4.0% in sludge–Soil C mixtures, while potassium peaked at 0.4% in sludge–Soil B with Trichoderma sp. These findings confirm that secondary sludge from beverage industry WWTPs can be processed into viable planting media or compost substitutes, supporting sustainable sludge management and circular economy practices.
