Supply Chain Design of Leaf Waste Biomass Pellets (New Renewable Energy) Based on Waste Banks asProducers (Case Study: Ciamis Waste Bank)

Abstract

Garbage is now a common problem that occurs in many places in Indonesia. Waste reduction activities 
are carried out with the aim that all levels of society, including the government, the business world, and the wider 
community, can carry out Reduce, Reuse, Recycle (3R) activities. The Ministry of Environment is developing a waste 
bank to carry out 3R activities by producing biomass pellet products from organic waste and biomass waste, namely 
leaf waste. Leaf waste biomass pellets for drive energy convection are able to support government programs to reduce 
coal consumption and become one of the solutions to replace coal in the future. Therefore, in this study there is a 
formulation of the problem, namely how much is needed for leaf waste biomass pellets to replace coal at PLTU 
Cirebon and how to design a supply chain for leaf waste biomass pellets to meet the need for new renewable energy 
to replace coal for PLTU Cirebon. Based on these needs problems, the objectives of this research are to find out how 
much leaf waste biomass pellets are needed and to design a supply chain for leaf waste biomass pellets to meet the 
demand for new renewable energy to replace coal for PLTU Cirebon. The research was conducted by researchers 
located at the Ciamis Main Garbage Bank and conducted at the Garbage Ecopreneur Training Center in Cimenyan, 
Bandung City. The data collection that was obtained started from the General Data of the Ciamis Main Garbage Bank 
to the method of making leaf waste biomass pellets. Furthermore, for data processing the method used is to use a 
supply chain design framework, namely the Framework for Network Design Decisions (Shunil Chopra-Peter Meindl), 
in which there are 4 stages, namely Stage 1 Supply Chain Strategy, Stage 2 Determining the Location of a Waste Bank 
as a Producer of Fuel Pellets , Stage 3 Data Allocation for 10 Waste Banks, and Stage 4 Meeting the Needs of the 
Cirebon PLTU, followed by the Strength, Weakness, Opportunities, and Threat (SWOT) method, 5W + 1H Method, 
Waste Management Method at the Source (TOSS), Pellet Calculation Biomass, Vehicle Operating Costs (BOK), Net 
Present Value (NPV), and Interest Rate of Return (IRR). The calculation results to meet the needs of the Association 
of Indonesian Private Electricity Producers (APLSI) which is almost 4.2 million tons per month, the Ciamis Garbage 
Bank can supply fuel pellets to meet the need for a substitute for coal for one month as much as 2,890,590 Kg or 2.8 
million tons per month which means it can meet as much as 69% of the need for coalfired leaf waste pellets at PLTU 
Cirebon.
