PERANCANGAN MODEL PERSEDIAAN BAHAN BAKU UBI UNGU PADA PRODUKSI KERIPIK

Description:
Ubi ungu merupakan salah satu tanaman yang dibudidayakan di Indonesia dengan produktivitas yang cukup
tinggi. Salah satu pangan olahan dari ubi ungu adalah makanan ringan yang merupakan bagian dari sektor industri
Fast Moving Consumer Good (FMCG). Persaingan antar pelaku industri makanan ringan yang semakin ketat
berdampak kepada fluktuasi permintaan produk keripik ubi ungu. Ketidakpastian permintaan mengakibatkan
sering terjadinya ketidaksesuaian antara persediaan bahan baku ubi ungu dan kebutuhan aktualnya. Penelitian ini
bertujuan untuk menangani permintaan ubi ungu yang berfluktuasi dengan menggunakan simulasi sistem dinamis
agar diperoleh keuntungan yang maksimum. Penyelesaian permasalahan dilakukan melalui dua tahap yaitu
perancangan model peramalan yang optimal dan perancangan model persediaan menggunakan simulasi sistem
dinamis. Model sistem dinamis terdiri dari 2 sub model yaitu sub model persediaan dan sub model biaya
persediaan. Sub model persediaan dianalisis berdasarkan permintaan jumlah produksi keripik ubi ungu dan supply
ubi ungu, dengan menggunakan 4 skenario, dimana skenario 1 dilakukan tanpa perubahan kebijakan, skenario 2
menggunakan pengendalian persediaan, skenario 3 menggunakan model probabilistik model P dan skenario 4
melakukan gabungan antara penyesuaian peramalan permintaan dan probabilistik model P. Hasil simulasi dalam
28 periode menghasilkan keuntungan yang berbeda dari setiap skenarionya. Keuntungan tertinggi diperoleh bila
melakukan perencanaan produksi dengan skenario 4, yang merupakan gabungan antara metode peramalan dengan
model P dengan service level 90%, dengan keuntungan sebesar Rp 195.288.659.301 � 20.447.754.235. Skenario
4 dapat menghasilkan profit yang tertinggi karena dapat merencanakan kebutuhan material dengan optimal
sehingga tidak ada biaya simpan yang tinggi.
Alt. Description
Purple Sweet Potato is one of agricultural product that has been cultivated in Indonesia with high
productivity. One of the processed products from purple sweet potatoes is snacks. It is the part of Fast Moving
Consumer Good (FMCG) sector. The intense competition between snack industry players involves in the
fluctuating demand on purple sweet potatoes chips. The uncertain demand for purple sweet potatoes chips causes
a mismatch between supply of purple sweet potatoes and the actual needs. Therefore, this study was conducted to
handle fluctuating demands by using dynamic system simulations to get maximum profit. Problem solving was
done through two stages, namely designing optimal forecasting models and designing inventory models using
dynamic system simulations. The dynamic system model consisted of two sub-models, namely the inventory submodel
and
inventory
costs.
Inventory
sub-models
were
analyzed
based
on
the
demand
for
the
amount
of
production
of
purple sweet potato chips and purple sweet potato supply, using four scenarios, where scenario 1 was done
without policy changes, scenario 2 used inventory control, scenario 3 used probabilistic model P and scenario 4
performed a combination of demand forecast adjustment and probabilistic model P. The simulation results in 28
periods produced different benefits from each scenario. The highest profit was obtained when planning production
with scenario 4, which was a combination of forecasting method with P model with a service level of 90%, with a
profit of Rp 195,288,659,301 � 20,447,754,235. Scenario 4 can produced the highest profit because it could plan
raw material optimally so that there were no high savings costs.
