A R T I C L E I N F O A B S T R A C T Article History: 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 Duri Kosambi 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.

INTRODUCTION Fecal sludge is waste material resulting from the decomposition of human feces in a septic tank. Fecal sludge, as domestic waste from human waste, has a very high concentration of pollutants. Further processing is needed not to pollute the environment (Direktorat Jenderal Cipta Karya Kementrian PUPR, 2017). One of the fecal sludge management units is located at Duri Kosambi IPLT (Instalasi Pengolahan Limbah Tinja/Faecal Sludge Treatment Plant), West Jakarta. Processing at Duri Kosambi IPLT uses two systems: a conventional system and a mechanical system. The basic concept of conventional systems is to utilize microorganisms to set aside environmental parameters, whereas mechanical systems use physical and chemical processes to separate environmental parameters. The conventional system is maintained because of the low operating costs and relatively easy maintenance. The conventional system consists of a receiving and manual filtering unit, aeration pond unit, anaerobic pond unit, facultative pond unit, maturation pond unit, and final pond unit. The effluent resulting from wastewater treatment from fecal sludge treatment should meet the quality standards stipulated in the Regulation of the Minister of Environment and Forestry Number 68 of 2016 concerning Domestic Wastewater Quality Standards (Menteri Lingkungan Hidup dan Kehutanan Republik Indonesia, 2016). However, the quality TSS and ammonia NH3 of the effluent did not meet the quality standards. The effluent concentrations for TSS and Ammonia-N parameters were 54 mg/L and 41.16 mg/L, respectively (Fazhar & Febrina, 2016). This value still does not meet regulation (Menteri Lingkungan Hidup dan Kehutanan Republik Indonesia, 2016).
