| dc.description.abstract | PDP Kahyangan Jember is a regional company owned by the Government of
Jember Regency that has agroindustry ground coffee and roasted coffee. The problem
is that there was a mismatch between the company's production plan and the number of
consumer demand that cause the stock. The impact is that production costs will increase
because of the cost of storing and the production process becomes disrupted due to the
location of the product storage warehouse in place together with the production space.
The purpose of this research is to evaluate and to make a production plan model at
PDP Kahyangan Jember. The method used is fuzzy Tsukamoto with input variables in
the form of consumer demand and stock. The results showed that the prediction of the
quantity of ground coffee and roasted coffee in the past year (July 2017-June 2018)
resulted in a MAPE value of 16%. The MAPE value obtained is "good" because it was
in between 10-20%. The results of the fuzzy Tsukamoto model simulation for future
production plans are done by predicting the number of requests in advance using the
DES Brown method and the stock using the SES method. The forecasting results for the
number of requests for coffee were 3,304 kg, 3,261 kg, 3,219 kg, 3,176 kg, 3,134 kg, and
3,091 kg. While the stock forecasting results are 283 kg, 205 kg, 173 kg, 151 kg, 140 kg,
and 134 kg. Therefore, the production plan of coffee processed using fuzzy Tsukamoto
for July - December 2018 are 4144 kg, 4136 kg, 4130 kg, 4121 kg, 4110 kg and 4095 kg
respectively. | en_US |
