Abstract

Selama pandemi Covid-19 diperlukan ruang isolasi untuk menekan penyebaran virus. Di samping itu, penggunaan alat pelindung diri (APD) sekali pakai menjadi hal yang berpotensi merusak lingkungan. Salah satu cara untuk mengurangi dampak tersebut adalah melakukanr recycle limbah APD menjadi sandwich panel. Tujuan dari penelitian ini adalah untuk menganalisa hasil proses solidifikasi limbah APD menjadi sandwich panel. Variasi penelitian ini terdiri dari 4 variasi dimana memiliki waktu pengerasan 4 hari dengan beban 81 kg, 9 hari dengan beban 53 kg, 12 hari dengan beban 75,9 kg, dan 5 hari dengan beban 206 kg. Hasil uji kuat lentur terbesar terjadi pada sampel 5 hari dengan beban 206 kg menghasilkan nilai sekitar 0,003 Mpa. Uji ketahanan panas dan uji porositas air sampel tersebut juga baik dibandingkan dengan sampel lain.

Abstract

The high production and sufficient calorific value content of the fecal sludge make it can be made as a raw material for producing briquettes. This supports the world's program in an effort to create alternative energy to replace fossil fuels. The purpose of this research is to design a production building and storage of fecal sludge into briquettes in a sewage treatment company so as to minimize the potential hazards of the sludge (accidents in the work placement and the negative impact on the environmenty) as flammable hazardous waste. At the beginning of the design, 3 alternative designs were assessed using the Analytical Hierarchy Process (AHP) method. the chosen alternative is alternative 3 with the proposed redesign of the briquette storage building, production site, and fecal sludge storage area separately, where the sludge storage area which was originally a hangar was converted into a waste impoundment system. The building design criteria for alternative 3 are fire-resistant buildings whose specifications are regulated by the Indonesian National Standard 03-1736-2000 and several other regulations (PERMENLHK No. 12, 2020 and BAPEDAL No. 1, 1995). With a planned storage duration of 1 year, the waste impoundment is designed to cover an area of 2304 m3 of fecal sludge, 72 storage drums for carbonated sludge, and 95 storage drums for fecal sludge briquesttes. In addition, the waste impoundment design is based on the PERMENLHK standard No. 12 of 2020. Waste impoundment can reduce the pH and Total Suspended Solid (TSS) of hazardous waste to below the quality standard threshold. the acidity level of the waste can be neutral to pH 7.79 (threshold 6-9), and TSS down to 86.67 mg/l (threshold 200 mg/l). The results of this study can make a major contribution to the field of hazardous waste management, especially fecal sludge, not only for Indonesia but also for countries that have similar conditions.

Abstract

This design contains the process of designing a Reduce, Reuse, Recycle (3R) Waste Processing Facility that can handle residential waste in Selapajang Jaya Sub-district. The objective of this design is to create a recommendation for a 3R Waste Processing Facility that complies with the 3R Waste Processing Facility Technical Guidelines and can reduce waste volume before being transported to the Landfill (TPA). Additionally, the design includes a budget plan covering investment costs, operational and maintenance costs, and assumptions about the revenue received by the 3R Waste Processing Facility. There are 3 design alternatives that will be selected using the Utility Theory and Compromise Program methods. The chosen best alternative involves processing organic waste using hollow brick boxes and plastic waste using a shredder machine. This design is capable of handling a waste generation of 22.449 m3/day from 1.952 households in Selapajang Jaya Sub-district. The facility includes waste sorting area, residue storage area, plastic waste processing area, organic waste processing area, warehouse, office, security post, and toilets. Theoretically, this 3R Waste Processing Facility can reduce the amount of waste by 61.17%. The design requires an investment cost of Rp 434,370,815 with a monthly operational and maintenance cost of Rp 45,781,470, and an estimated monthly revenue of Rp 94,148,061 for the 3R Waste Processing Facility.
