Introduction

Solid waste management has become an important issue ideveloping countries

Several problem may arise due to Increased rate o uncontgeneration

!hereore, this lead to various problems such as environmepublic health and politics

"aste management is not only mitigate and reduce the imsystems, but also involves the incorporation o the value o

the waste management system has a high important role iservice and have comple# problems$

+onsidering the ratio o waste achieved by the year 569: aor around 9:$F, there are still unserved

!he ratio o waste reduction is re.uired in each periodG it nimplemented so that application o si# sigma methods o wreduction goals can be achieved$

It is assumed that the cleanliness department to improve s

about 5F, which means a reduction in waste o 5$5F was !hus, this target can be e#pected sigma level targets$

"easure

In this phase there are several key steps, such as process collection, and counting o sigma level

!he use o si# sigma maps used to understand in more detprocess o solid waste management and the relationship bactors$

"ith the application o si# sigma maps are e#pected to kno

that can generate waste$ 2y knowing the elements o this process, there are several

that may aHect the rate o waste generation such as, Disp*inimation, +ollecting, !ranser, Recycling and +omposting

Improve

Trafc jam may be done in several ways, such as, avoid locations that occur in road congestion, move or change the time o transport on days there are no bottlenecks$

Organic waste, activities that can be done to reduce the generation o especially organic waste by reducing the purchase o goods that are tailocapacity$

Lack o awareness and lack o KAP, several intervention approachesparties such as governments, nongovernmental organi&ations, and acad

interventions in the community are absolutely necessary to in?uence andpublic mindset towards healthy behavior to reduce waste rom source$
