Abstract

Pengendalian persediaan merupakan hal penting bagi suatuperusahaan untuk mengetahui jumlah frekuensi pemesananyang tepat untuk perusahaan tersebut sehingga dapat meminimalisirkan biaya persediaan yang ada. PT. XYZmerupakan perusahaan yang bergerak di bidang pengerjaankayu. Produk yang dihasilkan oleh perusahaan yaituButsudan modan. Sejak 3 tahun terakhir terdapat beberapamaterial kayu nyatoh dan juga hardboard yang tersimpan di gudang yang menyebabkan tingginya cost dalam menyimpanbahan baku. Tahun 2021 tercatat total cost yang dikeluarkanperusahaan untuk persediaan bahan baku kayu nyatoh dan hardboard mencapai Rp424.762.952. Pada penelitian iniakan di terapkan model Dynamic Lot Sizing yaitumenggunakan metode Period Order Quantity, metode Least Unit Cost, metode Silver Meal Algorithm serta metode Algorithm Wagner-Within untuk mengendalikan sertamenentukan metode yang paling optimal yang dapat di terapkan oleh perusahaan. Hasil penelitian didapatkanbahwa metode Silver Meal Algorithm merupakan metodeyang optimal untuk digunakan karena mampu memiliki total cost yang rendah sehingga mampu menghemat total cost hingga Rp52.630.477. Metode Silver Meal ini dapatditerapkan oleh perusahan karena mampu meminimkan total cost yang di keluarkan serta mempertimbangkan kapasitasgudang yang ada pada perusahaan.

Abstract

This study aims to analyze factors influencing the usage of MyTelkomsel application based on Technology Acceptance Model (TAM) theory. Data are collected using offline questionnaires distributed to MyTelkomsel application users in Makassar region and its surrounding areas. Data analysis is performed using multiple linear regression after conducting tests for validity, reliability, and classical assumptions. The results of the F-test indicate that overall, all variables collectively influence the usage variable. The results of the partial t-test show that trust, habit, perceived usefulness, and attitude are proven to be influential factors in the usage of MyTelkomsel application, while perceived ease of use and subjective norm do not have a significant impact. This study obtains an adjusted R-Square of 0.577, indicating that the examined factors can explain approximately 57.7% of the variation in the usage of MyTelkomsel application.
