Abstract

PT X is a chemical manufacturing company specializing in the production of phosphoric acid and sulfuric acid. In addition to waste generated from production processes, PT X also produces domestic wastewater originating from supporting activities such as employee barracks, offices, and laundry facilities. This domestic wastewater contains parameters that can potentially pollute the environment, such as BOD, COD, TSS, ammonia, and Total Coliform, some of which exceed the quality standards set by the Minister of Environment Regulation No. 68 of 2016. This study aims to design an effective Domestic Wastewater Treatment Plant (DWTP) system to process the domestic wastewater of PT X. The proposed DWTP system consists of a collection tank, Anaerobic Baffled Reactor (ABR), Aerobic Biofilter, and disinfection unit. Each unit is designed to reduce pollutant parameters to meet quality standards. Based on the calculations, this system can handle a wastewater flow rate of 21.91 m³/day with high treatment efficiency for critical parameters. The study results indicate that the proposed DWTP design can reduce environmental pollution, improve wastewater treatment operational efficiency, and comply with applicable regulations. Implementing this system is highly recommended to ensure environmental sustainability and the continued operations of PT X.

Abstract

Literacy and numeracy skills are essential competencies for students to face the challenges of the 21st century. However, research findings indicate that students' literacy and numeracy skills in Indonesia still need improvement. Problem-Based Learning (PBL) can serve as an alternative model to help enhance students' literacy and numeracy skills through a student-centered learning process. This study aims to conduct a literature review focusing on the design and implementation of PBL in improving students' literacy and numeracy skills. The method used is a literature study with four main stages: determining the theme, searching and selecting literature, analyzing and synthesizing literature, and organizing the writing. The literature review results show that PBL can encourage students to be more active, think critically, and collaborate, which can contribute to enhancing literacy and numeracy skills. Furthermore, the literature review identifies factors that may influence the successful implementation of PBL, including the role of teachers, availability of resources, student engagement, and school policies. This literature review is expected to provide insights for teachers to optimize problem-based learning as an effort to improve students' literacy and numeracy skills.
