Abstract

This study examines the influence of demand forecasting on raw material inventory control at CV Wery Group Gunungsitoli. The research was motivated by challenges in managing inventory due to fluctuating market demand, which often caused overstocking or stock shortages, leading to inefficiencies in operations. A quantitative research method was employed, with data collected through questionnaires distributed to 30 employees. The data were analyzed using SPSS version 27, including validity and reliability tests, normality and heteroscedasticity tests, simple linear regression, and a T-test. The findings revealed a significant positive relationship between demand forecasting and raw material inventory control, indicated by a regression coefficient of 0.802 with a significance level of 0.000 (p < 0.05). The coefficient of determination (R²) was 0.711, meaning that 71.1% of the variation in inventory control can be explained by demand forecasting. This implies that the more accurate the demand forecasting, the more effective the inventory control. The study suggests that CV Wery Group should improve forecasting capabilities as a strategic tool to enhance operational efficiency and support production continuity.

Abstract

Penelitian ini dilakukan pada Toko Geuliss Bakery & Cake yang bergerak pada industri roti dan kue dengan menganalisis efisiensi rantai pasokan dalam pendistribuan produk. Penelitian ini bertujuan untuk mengetahui proses alur rantai pasokan dalam pendistribusian produk kepada konsumen, kendala yang dihadapi dalam distribusi produk serta upaya yang dilakukan dalam meningkatkan efisiensi rantai pasokan agar pendistribusian produk berjalan optimal pada Toko Geuliss Bakery & Cake. Metode yang digunakan yaitu pendekatan kualitatif dengan melakukan wawancara kepada 6 informan. Hasil wawancara menunjukkan bahwa ketersediaan bahan baku dan stok produk relatif terjaga, meskipun pencatatan manual masih menimbulkan risiko kesalahan. Sistem distribusi berjalan terstruktur dengan menerapkan prinsip sesuai urutan masuk (First In, First Out), kecepatan, ketepatan, serta pemeriksaan berlapis guna menjaga akurasi pengiriman. Namun, toko menghadapi beberapa kendala, seperti keterbatasan armada, keterlambatan pasokan, faktor eksternal (cuaca dan kondisi jalan), serta biaya distribusi yang tinggi akibat jarak pengiriman dan pembelian mendadak. Untuk mengatasi hal tersebut, Toko Geuliss Bakery & Cake menerapkan berbagai strategi, antara lain penambahan tenaga kerja sementara, penyediaan stok cadangan, pembuatan produk setengah jadi, pengaturan rute efisien, penggabungan pesanan, serta penerapan SOP sederhana guna meminimalisir kesalahan. Secara keseluruhan, hasil penelitian menunjukkan bahwa manajemen rantai pasokan yang baik berkontribusi pada peningkatan kepuasan pelanggan, meskipun masih diperlukan perbaikan, khususnya pada aspek digitalisasi pencatatan dan penambahan armada distribusi agar efisiensi lebih optimal.

Abstract

This research is motivated by the phenomenon of cafe business competition in Gunungsitoli City, which demands effective marketing strategies, particularly in the utilization of promotional mixes and business location selection. The purpose of the study is to analyze how promotional mixes and location aspects play a role in increasing sales at Murai Coffee Gunungsitoli. The research method used is a qualitative approach with data collection techniques through interviews, observation, and documentation. The research informants consisted of the owner, employees, and customers of Murai Coffee.

Abstract

This study highlights the problem of managing teak wood raw materials in the form of boards at UD Gemilang, Gunungsitoli City. The company often experiences shortages or excess inventory due to a conventional ordering system that is not based on optimal demand calculations. This inefficiency causes wasteful costs and disrupts the smooth production process. The main objective of this study is to analyze current inventory management and apply the EOQ (Economic Order Quantity) method to determine the optimal order quantity, as well as evaluate its impact on cost efficiency and production operations. The EOQ method is expected to be a systematic and rational solution for managing inventory more efficiently. This study uses a descriptive quantitative approach. Data were collected through direct interviews with business owners and documentation of raw material purchasing and usage reports for 2024. The analysis was conducted using the EOQ formula to calculate the optimal order quantity, ordering costs, storage costs, safety stock, reorder point, and total inventory cost (TIC). The analysis results show that the optimal order quantity for teak wood raw materials is 282 boards, with an ordering frequency of 6 times a year. This number is more efficient than the actual ordering system which is carried out monthly without a fixed calculation. The recommended safety stock is 22 boards, with a Reorder Point (ROP) of 36 boards. The implementation of the EOQ method successfully reduced total inventory costs from Rp6,768,000 to Rp3,496,800.
