Abstract

Brackish water is a water resource that has the potential to be used as raw water, but has limitations due to high levels of total dissolved solids (TDS) This study aims to analyze the effectiveness of the electrocoagulation method in reducing these pollutant parameters in brackish water samples from Subang Regency. The groundwater samples were taken in the area of the Diniyah Takmiliyah Awaliyah Islamic Madrasa School. The research was conducted using a prototype electrocoagulation device with a pair of aluminum plates, varying voltages (10, 12, 14, and 15 volts), varying flow rates (0.06 L/second and 0.08 L/second), and conditions with and without a plate settler in the sedimentation unit. The results showed that increasing the voltage significantly reduced TDS levels. The highest efficiency was achieved at 10 volts with a flow rate of 0.06 L/second, reducing TDS from 3,400 mg/L to 3,110 mg/L (8.5%). Meanwhile, the lowest efficiency was achieved at 12 volts with a flow rate of 0.08 L/second, at 2.1%. Overall, this study confirms that electrocoagulation can be an alternative brackish water treatment technology in coastal areas. Although the TDS reduction efficiency is still limited, this method can be further developed as part of an integrated system to support sustainable clean water availability.

Abstract

Source of raw water used at Badak Singa Water Treatment Plant come from surface water such as Cisangkuy River. This source of raw water is affected by conditions in the upstream, pollution along the stream, climate and weather. In the drinking water supply system, turbidity is one important factor for several reasons such as aesthetic factor, burden to filtration, and interfere the disinfection process. Electro coagulation is one of water treatment method that combines the process of coagulation, flotation, and electrochemical. Aims: This research aims to see at the ability of the electro coagulation process in reducing turbidity as an alternative to substitute the conventional coagulation system. Methodology and results: This research carried out by testing electro coagulation with variations in mixing, current density produced by voltage 10, 20 and 30 volt and detention time 5, 10, 20 and 30 minute to reduce the initial turbidity of 100 NTU. The result are that: the efficiency of electro coagulation with mixing is better than electro coagulation without mixing to reduce the initial turbidity of 100 NTU; the final turbidity value of the processing result is better as the length of detention time used and meet the quality standard from detention time of 10 minute; the higher the current density given and the longer the detention time used, the higher the processing efficiency and the formed flock volume is deposited.  Conclusion, significance and impact study: A good turbidizing removal process using electrocoagulation requires the agitation process and long detention time.

Abstract

Traffic noise is a significant environmental issue in urban areas, adversely affecting public health and the quality of essential services. This study aims to evaluate the noise pollution levels at sensitive locations, consist of a health clinic and two schools in Bandung City, Indonesia. The research involves measuring noise levels, mapping their distribution, and analyzing the data. Measurements were conducted over four days using a smartphone application, Decibel X, to record noise levels every 5 seconds for 10-minute sessions across various times of the day. Simultaneously, vehicle counts were recorded to establish a correlation between traffic volume and noise levels. A questionnaire survey was administered to gather perceptions of noise impact from teachers, students, clinic staff, and patients. The findings revealed that noise levels at several points, particularly near busy roads, exceeded recommended standards, significantly disrupting concentration and causing physical symptoms such as headaches among respondents. Noise hotspots identified included Point1 and Point6, where average noise levels were consistently high, while Point4 and Point5 showed lower but more variable noise levels. To mitigate traffic noise, the study recommends a combination of installing noise barriers, creating green spaces, and enhancing building insulation. Regular noise monitoring and public awareness campaigns are essential for effective noise management and improving the quality of life in Bandung City.

Abstract

In exploring how household waste management contributes positively towards climate change mitigation in RW (sub hamlet) 06, Pasirluyu Sub District, Bandung, the objective of this study is to assess existing waste management practices; promoted community awareness as well as aligning them with climate actions like waste reduction programs through recycling and composting initiatives. Recommendation is suggested for enhancing household waste management, especially facing the climate change mitigation. A total of 10 representative households were followed for 30 days collecting data on their wastes generation, separation and treatment processes that included various types of waste such as organic, inorganic and residual where organic wastes were composted using a Takakura method. The findings reveal that between 40-60% of the total amount of household garbage are made up of organic substances while inorganic substances account for about 20-35% and lastly residuals constitute only 5-10%. Households managed to separate their wastes properly on one hand though on another incorrect sorting was noted complicated by inconsistent participation. Thus composting resulted into reduced amounts of organic waste going to landfills thereby minimizing methane emissions. But then again limited infrastructural facilities as well as low levels of understanding were some other barriers against enforcing these practices. Continuous community engagement, enhanced infrastructure, and policy support are essential for aligning waste management with climate change mitigation efforts in RW 06. The findings contribute to broader sustainability goals and highlight the potential for similar urban communities to adopt climate-conscious waste management practices.

Abstract

Perubahan iklim dapat mempengaruhi musim hujan dan kering di berbagai wilayah, salah satunya berpengaruh pada perubahan debit di Sungai Cikapundung sebagai salah satu sumber air baku  di Kota Bandung. Berdasarkan kondisi tersebut, maka pemodelan ketersediaan air baku perlu dilakukan. Pemodelan ketersediaan air baku sangat bergantung pada beberapa fenomena, salah satu diantaranya adalah pengaruh iklim. Pemodelan dinamika sistem merupakan pemodelan struktur independensi dengan fokus aspek endogen dari sebuah sistem untuk mendapatkan perilaku dinamis. Tujuan kajian ini adalah menyusun konsep model ketersediaan air menggunakan metode dinamika sistem agar dapat dilakukan prakiraan ketersediaan air di Kota Bandung, serta mengidentifikasi faktor-faktor eksternal yang dapat mempengaruhi model. Konsep pemodelan dinamika sistem dilakukan melalui beberapa tahapan, yaitu identifikasi dan perumusan masalah, konseptualisasi sistem, formulasi model, simulasi model, serta verifikasi dan validasi model. Konsep yang telah dituangkan dalam Causal Loop Diagram (CLD) dikembangkan menjadi model Stock Flow Diagram (SFD) untuk memprediksikan debit air sungai yang disimulasikan menggunakan Powersim Studio 10. Validasi model dilakukan melalui perhitungan Mean Absolute Percentage Error (MAPE).  Faktor yang teridentifikasi dapat berpengaruh sebagai variable input yaitu parameter iklim yang meliputi kelembaban, kecepatan angin, suhu, curah hujan, dan hari hujan.

Abstract

Pertumbuhan penduduk dan berkembangnya wilayah perkotaan menyebabkan kebutuhan air minum semakin meningkat. Sedangkan pelayanan air minum di sebagian besar wilayah perkotaan belum sepenuhnya terlayani. Untuk mengatasi hal tersebut, Upaya yang lebih banyak dilakukan adalah penambahan sumber air baru. Solusi ini tidak berkelanjutan karena konsumsi air akan terus meningkat dan apabila tidak dikendalikan maka kebutuhan air minum tetap tidak dapat dipenuhi dengan seimbang. Oleh karena itu diperlukan strategi yang dapat dilakukan untuk dapat mengendalikan pemakaian air minum.Penelitian ini bertujuan untuk menganalisis strategi pengendalian pemakaian air minum di Kota Malang. Metode analisis strategi yang digunakan dalam penelitian ini adalah analisis SWOT. Analisis dilakukan dengan mengidentifikasi faktor internal (strength atau kekuatan dan weakness atau kelemahan) dan factor eksternal (opportunity atau peluang dan threat atau ancaman), sehingga dapat diketahui strategi yang paling memungkinkan untuk diterapkan. Hasil analisis kuadran menunjukkan berada di kuadran I. Hal ini menunjukkan adanya peluang yang dapat dimanfaatkan dan kekuatan yang dimiliki lebih banyak daripada kelemahan. Strategi yang dipilih adalah strategi WO (Weakness-Opportunities), yang mencakup langkah-langkah seperti memanfaatkan potensi sumber air baku alternatif yang belum dimanfaatkan, mengoptimalkan kapasitas pelayanan, dan memanfaatkan regulasi dan strategi air minum aman sebagai upaya dalam pengendalian pemakaian air minum. Strategi ini diharapkan dapat menjadi alternatif dalam upaya pengendalian pemakaian air minum secara berkelanjutan.
