This study aims to analyze the effectiveness of raw material inventory control at the Kediri Wet Noodle business by comparing the traditional method with the Economic Order Quantity (EOQ) method. A descriptive quantitative approach was applied, utilizing EOQ, Safety Stock (SS), Re-order Point (ROP), and total inventory cost analysis. The results indicate that the traditional method leads to 24 purchase cycles per year with an inventory cost of IDR 4,320,000, without considering safety stock or re-order points. In contrast, the EOQ method shows an optimal purchase quantity of 1,421 sacks (35,525 Kg) with five purchase cycles per year, an inventory cost of IDR 574,455, a Safety Stock of 67 sacks (1,675 Kg), and a Re-order Point of 107 sacks (2,675 Kg). Therefore, the EOQ method reduces inventory costs by up to 86% compared to the traditional method. Nevertheless, its limitation lies in the exclusion of raw material shelf life and storage condition factors.

UD. Indokarya Brass is a company engaged in the brass handicraft industry with its main products being door handles and bells. The main raw materials used in the production process include brass, copper, tin, and aluminum, which are obtained from suppliers both within and outside the city. On average, raw materials are received weekly with quantities of 50–100 kg of brass, 7–10 kg of copper, 10–15 kg of tin, and 3–5 kg of aluminum. In addition, the company also uses additional materials in the form of thinner and epoxy purchased from nearby hardware stores with less frequent purchases, namely 5–10 liters of thinner every month and around 5 kg of epoxy every two months. To date, the company has not had a structured policy for procurement and control of raw material inventory. This condition results in excess inventory of several types of raw materials which actually incurs high costs, both in terms of storage costs and warehouse maintenance costs. This excess inventory ultimately has an impact on reduced efficiency and decreased company profits. This study was conducted to analyze the existing inventory system and compare the company's current policy with a proposed method for more optimal inventory control. The calculation results show that the proposed method is able to provide significant inventory cost savings, namely 83.25% in brass raw materials, 15.28% in copper, 14.6% in tin, 43.37% in aluminum, 4.66% in epoxy, 4.2% in thinner, and 40.7% in other raw materials. Thus, the implementation of the right inventory control method can improve operational efficiency and help companies reduce cost burdens, so that profits can be more optimal.

This study aims to analyze the process of preparing operational budgets in micro, small, and medium enterprises (MSMEs) of Pempek Love Palembang, which are engaged in the culinary sector typical of South Sumatra. Pempek Love Palembang is one of the business actors that plays a role in maintaining culinary traditions while contributing to the local economy. The research approach used is quantitative descriptive, with data collection techniques through direct interviews with business owners. Interviews are focused on operational activities that cover all stages of production to sales. The scope of analysis includes the preparation of various budget components, including sales budgets, production and inventory costs, raw material budgets, direct labor budgets, overhead costs, operational costs, cost of goods sold (COGS), and profit and loss budgets. Based on the findings, it is known that Pempek Love Palembang has not prepared a budget systematically and well documented. This is due to the limited knowledge of owners and employees about the concept of budget planning, so that the financial management process runs less than optimally. The absence of a structured budget makes it difficult to evaluate performance in a measurable manner and limits the ability of businesses to project profits accurately. This study confirms that the implementation of a good operational budget is not only beneficial for setting clear targets, but also serves as a cost control tool and a basis for strategic decision-making. With proper budget planning, MSMEs such as Pempek Love Palembang can increase efficiency, maintain financial stability, and expand business development opportunities in the future. The recommendation of this study is simple financial management training for MSME actors to be able to prepare budgets independently, accurately, and sustainably for more sustainable and stable business growth.

This study aims to determine the effect of pricing, sales promotions, and stock availability on sales volume at H&G Collection. In an era of increasingly fierce business competition, companies need to manage marketing strategies effectively to maintain and increase sales. Appropriate pricing can influence product appeal to consumers, planned sales promotions can increase purchasing interest, while maintained stock availability ensures that consumer demand is met without interruption. This study used a quantitative approach with primary data sources obtained through questionnaires. The population in this study was all H&G Collection employees in the marketing, finance, and general administration divisions. The sampling technique used a saturated or census sampling method, where all members of the population were sampled. The number of respondents involved in this study was 37. The research instruments were tested for validity and reliability before being used in data collection. The data obtained were analyzed using SPSS version 19 software. The analysis methods included classical assumption tests, multiple linear regression analysis, t-tests, and F-tests to determine partial and simultaneous effects between variables. The results of the study indicate that the three independent variables, namely pricing (X₁), sales promotion (X₂), and stock availability (X₃), have a significant effect on the dependent variable, namely sales volume (Y). This proves that the right pricing strategy, effective promotions, and optimal inventory management can significantly increase sales volume. This finding implies that H&G Collection management needs to maintain and even improve the quality of the implementation of these three variables in an integrated manner to support sales growth and the company's competitiveness in the market.

This study aims to evaluate the effectiveness of current asset management, specifically cash, receivables, and inventory, and its impact on a company's ability to generate profits. The study focused on companies in the automotive sector listed on the Indonesia Stock Exchange (IDX) from 2020 to 2023. The research approach used a quantitative method with secondary data sourced from annual financial reports. The study sample included 11 companies, resulting in a total of 44 observational data sets over four years. Data analysis was performed using SPSS version 25 software to examine the relationships and influences between the study variables. The test results showed that cash management did not significantly influence profitability. This indicates that the amount of available cash does not always correlate with profit, possibly because cash funds are not optimally utilized in productive activities. Conversely, receivables management showed a negative correlation with profitability. This finding suggests that high receivables can burden cash flow and reduce a company's ability to generate profits. Meanwhile, inventory management has a positive and significant impact on profitability, indicating that good inventory control can support smooth production and sales, thereby increasing profits. Together, these three variables explained 68.4% of the variation in company profitability, while the remaining 31.6% was influenced by factors outside the model, such as operational efficiency, cost structure, and marketing strategy. These findings provide insights for automotive company management to prioritize inventory management and review cash and receivables policies to optimize financial performance.
