| Summary: | To solve the overcapacity problem in landfill, government has started a program to
build a communal waste processing facility called Tempat Pengolahan Sampah Reduce,
Reuse, Recycle (TPS3R). However, after conducted some observation to typical TPS3R, it
was known that TPS3R still has a lot of drawbacks. One way to solve the problems is by
replacing the conventional waste processing system by using thermal-based technologies that
has higher processing percentage and rate. Therefore, this final project discusses the design
process of thermal technology-based waste processing facility is to replace the conventional
one.
Seven design alternatives were compared to each other by Analytical Hierarchy
Process (AHP) according to several parameters, such as: the processed waste percentages,
specific processing capacity, energy sustainability, Global Warming Potential (GWP), and
daily cash flow. The design with highest value in AHP matrix was selected as the
recommended design system to be applied. The financial feasibility and sensitivity analysis
of the selected design was also conducted to study its implementation feasibility. The
analyzed financial parameters are Net Present Value (NPV), Discounted Payback Period
(DPBP), and Internal Rate of Return (IRR)
Based on the determined parameters, design alternative that combined sorting,
hydrothermal, pyrolysis, incineration, and landfilling processes was the most recommended
system. This design excelled other alternatives in processed waste percentages, daily cash
flow, and the GWP; though, it lacked in the specific processing capacity and the energy
sustainability. The value of NPV, DPBP, and IRR were IDR 4,359,908,623, 3 years and 4
months, and 34.5%, respectively, which made it feasible to be implemented.
