Abstract

ABSTRAK Tujuan penelitian ini adalah untuk menganalisis pengendaliaan persediaan bahan baku menggunakan metode Economic Order Quantity (EOQ) di Departemen Spinning PT. Unitex untuk memperlancar proses produksi. Penelitian ini menggunakan pendekatan kuantitatif, dengan metode pengumpulan data yaitu dengan wawancara dan observasi langsung ke dalam perusahaan. Metode yang digunakan dalam penelitian ini adalah dengan analisis deskriptif. Hasil penelitian ini menunjukan dengan metode Economic Order Quantity (EOQ) dapat membantu perusahaan Departemen Spinning PT. Unitex dalam melakukan pengendalian persediaan bahan baku yang optimal yaitu sebesar 135.521,3 Kg Cotton dalam setiap satu kali pemesanan dengan frekuensi pemesanan sebanyak 10 kali pemesanan dalam satu periode. Dan untuk bahan baku Polyester sebanyak 620,97 Kg dalam setiap satu kali pemesanan dengan frekuensi pemesanan sebanyak 9 kali pemesanan dalam satu periode. Kelancaran proses produksi pun meningkat 11,6% dari 88,4% menjadi 100%, maka proses produksi dapat dikatakan lancar. Dalam penelitian ini diketahui persediaan bahan baku yang tepat akan mendukung kelancaran proses produksi sehingga tidak terjadi kekurangan dan kelebihan bahan baku. ABSTRACT The purpose of this study was to analyze the control of raw material inventory using the Economic Order Quantity (EOQ) method in the Spinning Department of PT. Unitex to streamline the production process. This study uses a quantitative approach, with data collection methods, namely interviews and direct observation into the company. The method used in this research is descriptive analysis. The results of this study indicate that the Economic Order Quantity (EOQ) method can help the Spinning Department company PT. Unitex in controlling the optimal raw material inventory is 135,521.3 Kg Cotton in every one order with an order frequency of 10 orders in one period. And for Polyester raw materials as much as 620.97 Kg in each order with a frequency of 9 orders in one period. The smoothness of the production process also increased 11.6% from 88.4% to 100%, so the production process can be said to be smooth.

Pada saat hari senggang (Selasa dan Kamis) sistem antrian dengan menambahkan satu unit menjadi tiga kasir dan tiga barista memiliki kinerja yang paling baik dengan tingkat pelayanan yang optimal terlihat dari hasil total cost yang paling minimum sebesar Rp 178.752,00  dan tingkat efisiensi  tinggi sebesar 160% . Sedangkan, hari teramai (Sabtu dan Minggu) sistem antrian dengan menambah dua unit menjadi empat kasir dan empat barista memiliki kinerja yang paling baik dengan total cost yang paling minimum sebesar Rp 201.009,00 dan tingkat efisiensi  tinggi sebesar 275%. Abstract In the last two years, coffee shops no longer only offer their specialty coffee blends and offerings. However, things about the coffee shop concept become reinforcement for coffee shop owners to optimize service quality and efficiency. The purpose of this research to find out the analysis of queuing system at the MSME coffee shop Daong in an effort to increase the efficiency service. The kind of research used is descriptive (explorative) quantitative. Quantitative data was used in the study of secondary data and primary data based on time of cross section data. The method of analysis that used the descriptive analysis, quantitative analysis (queuing system) by using multiple channel multiple phase method, trade off, and service efficiency level. The result show that comparative analysis of three real conditions, the addition of one unit, and the addition of two units. On weekdays (Tuesday and Thursday) the queuing system with the addition of one unit to three cashiers and three baristas has the best performance with an optimal level of service as seen from the minimum total cost of IDR178,752 and high efficiency rate of 160%. Meanwhile, on weekends (Saturday and Sunday) the queuing system with the addition of two units to four cashiers and four baristas has the best performance with an optimal level of service as seen from the minimum total cost of IDR201,009 and high efficiency rate of 275%.

Abstract

Purpose – This study develops and tests an integrative model of sustainable consumer behavior (SCB) among Generation Z in Bogor City by examining the influence of Emotional Intelligence (EI), Social Influence (SI), and Perceived Value Alignment (PVA) on SCB through Sustainable Consumer Intention (SCI) mediation. Theoretically, this research extends the Theory of Planned Behavior (TPB) by integrating affective, social, and value alignment dimensions. Design/methodology/approach – This quantitative research uses a survey of 401 Generation Z students in Bogor City which was analyzed with SEM-PLS. Finding/Results – The results showed that EI and PVA had a significant positive effect on SCI and SCB, while SI had no direct effect on SCB. The model demonstrated a very high predictive ability for sustainable consumer behavior (0.873), indicating that the influence of external factors and emotional capacity is mediated by behavioral intentions before manifesting in sustainable consumption actions. SCI emerged as the most dominant mediator, confirming the critical role of behavioral intentions in translating social influences into sustainable consumption behavior. Originality/Value – This research provides an integrative framework that extends TPB by combining EI, SI, and PVA to explain sustainable consumer behavior, offering theoretical insights and practical implications for promoting sustainable consumption among Generation Z.
