Abstract

Daur ulang air limbah adalah salah satu dari kriteria inovasi berkelanjutan dalam tingkat perguruan tinggi. Reklamasi air dari sistem pembuangan limbah untuk kegiatan berkebun merupakan salah satu cara untuk mencapai target tersebut di Universitas Pertamina. Tujuan dari penelitian ini adalah mendesain dan memverifikasi unit pengolahan air dari saluran limbah menjadi air siap pakai untuk kegiatan berkebun. Unit yang dibutuhkan untuk sistem pengolahan air limbah adalah tangki pengumpulan, Horizontal Roughing Filters (HRF), Rapid Sand Filtration (RSF), reservoir, dan desinfeksi. Kualitas efluen yang diharapkan dari unit pengolahan adalah TDS 278 mg/L, TSS 1,3 mg/L, Kekeruhan 0,17 NTU, BOD5 0,63 mg/L, COD 6,12 mg/L, Fosfat total 0,95 mg/L, Nitrat 0,07 mg/L, deterjen 0,7 mg/L, dan total coliform MPN/100mL. Parameter yang paling penting dalam proses pengolahan air sewerage adalah total coliform yang harus mencapai efisiensi sebesar 99%. Pengolahan air dengan cara konvensional ini digunakan karena ketersediaan lahan yang masih mencukupi, jika tidak mencukupi maka diperlukan pengolahan lanjut yang efisien, ramah lingkungan, dan bernilai ekonomi.

Abstract

South Jakarta has the highest rainfall concentration and the most flood location in Jakarta. Therefore, an urban drainage system is needed to control surface water so flood can be prevented. This research aims to support the urban drainage system planning by determining rainfall intensity based on three methods, those are Van Breen, Bell Tanimoto, and Hasper der Weduwen. The most suitable method will be selected by comparing the value of rainfall intensity with Talbot, Sherman, and Ishiguro approach. This research reveals that the most suitable method is the Van Breen Method with the Talbot equation. The result of the calculation is rainfall intensity for 2, 5, 10, 25, 50, and 100 years rain return period, with each range 27.2 – 182.8 mm/hour, 36.8-197.6 mm/hour, 43.1-206.3 mm/hour, 51.1-216.6 mm/hour, 57-223.9 mm/hour, and 63-230,8 mm/hour.

Abstract

The ammonia and total suspended solids (TSS) content in the wastewater of IPLT Duri Kosambi Jakarta City still does not meet the standard. It requires further processing that needs to be applied. The three treatments that are used as alternatives are GAC Adsorption, Zeolite Adsorption, and Built-Up Wetlands. The purpose of this study is to analyze the best alternative suitable for use as advanced processing in IPLT DuriKosambi with analysis of decision-making analysis. Analysis decision-making is carried out using the analytical hierarchy process (AHP) using four criteria: construction costs, TSS removal efficiency, ammonia removal efficiency, and Human Resources (HR) requirements. The highest scores of the GAC Adsorption, Zeolite Adsorption, and Constructed Wetland alternatives were 0.41; 0.30l, and 0.28. So that the GAC unit is the unit selected based on the criteria set in the AHP criteria.

Abstract

ABSTRACT. Fecal sludge can be treated by conventional treatment such as pond stabilization which is commonly used to reduce organic concentrations. However, nutrients such as NH3 are still widely measured in the effluent. One of the sewerage treatments in the city of Jakarta, for example, experienced this condition. This study aims to design an appropriate technology to increase the efficiency of nutrient ammonia and total suspended solid (TSS) removal at Duri X IPLT. The unit added in the selected effluent treatment is Granular Activated Carbon (GAC). Design considerations are the characteristics of activated carbon, operating conditions (discharge and contact time), and operating mode (fixed-, expanded-, or fluidized-bed, pumped, or gravity flow). The Carbon Usage Rate for removing ammonia and TSS is 1.384 g/L and 0.378 g/L, respectively. Maintenance is required so that the granular activated carbon (GAC) unit can continue operating and functioning properly. Blockages in carbon transport pipes can occur in many pipes. This can occur due to a too-small pipe, a short bend radius of the pipe, a lack of speed, and a lack of cleaning of the pipe. The eroded pipe is also a common problem that often occurs in unlined mild steel and fiberglass reinforced plastic (FRP), usually in sharp bends.Keywords: Sewerage, ammonia, TSS, design, GAC

Abstract

This study examines the public perception of several Jakarta communities served by communal WWTPs on in situ management or wastewater sources and the relationship between factors. This research used a questionnaire and random sampling technic. The questionnaire is based on study indicators. This study uses nine domestic wastewater indicators. The corrected Item-Total correlation indicates that the variable is invalid and does not need to be continued to the reliability test. The Kaiser-Meyer-Olkin (KMO) and Bartlett's Test showed that factor analysis is appropriate. This study groups indicators into four dimensions. Factor 1 includes septic tank draining, sewage treatment, subscribing to sewage treatment, feces sludge management, and sewage sludge disposal. Second, septic tank performance and draining. Third, open defecation and septic tank owner are factors 2 and 4. Fourth, delete indicators with the same variable but different dimensions.
