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

21st-century learning requires all teachers to implement learning that integrates information and communication technology (ICT). The use of ICT in learning can be realized well if teachers can integrate technology, knowledge, and pedagogical expertise in teaching or what is known as Technological Pedagogical Content Knowledge (TPACK). One way to apply TPACK in learning is to develop Augmented Reality-based learning media. Teachers at MTs PPMI Assalaam have not mastered and applied technology in learning, especially Augmented Reality-based learning media. Based on this situation, the service team felt it was essential to increase TPACK knowledge and prepare Augmented Reality-based learning media through training. The results of the pretest and posttest after training showed an increase, and the participants' response to the service activities through a satisfaction questionnaire was said to be very good.
