The results showed that of<br>the 20 days sample that was 6,540 tails, it was found that the number of slaughtered chickens was 2,230<br>chickens with the details of bruised chicken heads, broken chicken wings, bruised chicken body parts, less<br>clean feather extraction, and internal taking. not clean enough. While the company's performance<br>measurement is at Sigma 3.85 level with a 9.292 DMPO value, which means that in 1 million pieces of<br>chicken there are 9,292 chickens that are deformed. From the Pareto diagram, it is known that 80% of the<br>defects are broken chicken wings and bruised chicken parts. Then from the cause and effect diagram it is<br>known that human resource factors are the main cause of broken chicken wing flaws and bruised chicken<br>body parts, therefore from the results of this study the company needs to improve quality with more<br>discipline towards human resource operational standards and conduct supervision and evaluation of<br>employee performance.</p> <p>Keywords: Pareto, Quality Improvement, Cause and Effect, Six Sigma-DMAIC.</p> 2019-06-30T00:00:00+00:00 Copyright (c) http://ejournal.unhasy.ac.id/index.php/reaktom/article/view/420 ANALISIS DAMPAK LALU LINTAS AKIBAT PEMBANGUNAN WISATA ALAM DESA MEDOWO KECAMATAN KANDANGAN KEDIRI 2019-06-30T07:32:05+00:00 Maulida Nurunnafissa nafissamaulida@gmail.com Tri Rijanto tririjanto@unesa.ac.id Abdiyah Amudi abdiyah.amudi@yahoo.com <p>Medowo village is one of the villages in Kandangan Districts residing in hilly area.
