Abstract

This study aims to analyze the application of the time series method using the Moving Average approach to forecast raw material requirements at UD. Tunas Baru, Gunungsitoli City. The company has traditionally managed its inventory without a systematic calculation basis, resulting in fluctuating purchases and usage that cause overstock and shortages. This research employed a descriptive quantitative method using data on wood board purchases and usage from January to December 2024.The results show that the Moving Average (3-period) method provides a general overview of raw material demand trends, although it remains less accurate in capturing sharp fluctuations. The Mean Squared Error (MSE) value was 27,338 (sheets²), indicating a relatively high deviation between actual and forecasted values.These findings suggest that time series-based forecasting can serve as a preliminary foundation for raw material planning at UD. Tunas Baru. Applying an appropriate forecasting method can help the company minimize inventory imbalance risks and improve production efficiency. It is recommended that the company implement a data-based inventory management system and consider more adaptive forecasting methods such as Weighted Moving Average or Exponential Smoothing.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh distribusi terhadap kepuasan pelanggan pada CV. Lenta Lafau. Penelitian menggunakan pendekatan kuantitatif dengan metode survei melalui penyebaran kuesioner kepada pelanggan perusahaan. Populasi dalam penelitian ini berjumlah 30 pelanggan dan seluruhnya dijadikan sampel menggunakan teknik total sampling. Data dianalisis menggunakan uji validitas, uji reliabilitas, analisis korelasi, regresi linear sederhana, koefisien determinasi, dan uji hipotesis dengan bantuan aplikasi SPSS. Hasil penelitian menunjukkan bahwa distribusi memiliki hubungan yang kuat dengan kepuasan pelanggan dengan nilai koefisien korelasi sebesar 0,708. Hasil analisis regresi linear sederhana menunjukkan bahwa distribusi berpengaruh positif terhadap kepuasan pelanggan dengan persamaan regresi Y = 7,975 + 0,748X. Nilai koefisien determinasi sebesar 0,501 menunjukkan bahwa distribusi memberikan kontribusi sebesar 50,1% terhadap kepuasan pelanggan, sedangkan sisanya dipengaruhi oleh faktor lain di luar penelitian. Hasil uji hipotesis menunjukkan nilai signifikansi sebesar 0,000 (<0,05), sehingga dapat disimpulkan bahwa distribusi berpengaruh positif dan signifikan terhadap kepuasan pelanggan pada CV. Lenta Lafau. Temuan ini menunjukkan bahwa peningkatan kualitas distribusi dapat meningkatkan kepuasan pelanggan.
