Keywords : Internal Control of Raw Material Inventory. Production Process Planning. and Smoothness of Production Process . INTRODUCTION Raw materials are very important in running a production plan because they are one of the important elements in the procurement process. Therefore, raw materials are one of the components that must receive special attention during the production process. Planning for the right raw material inventory greatly supports the smooth running of the production process. The smooth running of the production process is very important for the company because it greatly affects the level of sales and profits obtained by the company. If the stock of raw materials is not available in the required amount, then this will have a negative impact on the company, namely affecting the company's profits. This is due to the costs incurred due to the company running out of stock which results in the loss of the opportunity to make a profit because consumer demand cannot be served, the production process is disrupted. Internal control is the organizational plan and business methods that protect assets, provide accurate and reliable information, facilitate and improve operations.

Jurnal Logistik Indonesia Vol. No. April 2024, pp. E-ISSN 2621-6442 Based on Figure I. 1, it shows that there is a difference between the raw materials for polybags, partdrape, and cutting in the period January - May which resulted in disruption in the production Based on the results of observations before the research, the problems that occurred at PT. Hogy Indonesia in the Over All Drape Production Department were that there were often obstacles in the production process. One of them is from the raw materials that are late in being procured in the manufacture of partial raw materials by the polybag department, also the large number of HP/SR fabrics that are rejected due to the poor quality of the material, of course making the production process not smooth causing the daily output not to be achieved. Figure 2. Target Achievement Achievementtarg January 5,07 4,76 4,65 February March April May Target 2024 Actual 2024 Source: Achievement of Over All Drape Department targets Then, there are frequent shifts or changes in the raw material code which causes the fabric code to be changed and QC tests must be carried out again to see whether the product can run or not, whether the product is good or not, so that it takes a long time again and must be rescheduled. In addition, in the planning of the production process for orders that are sent to the Non Heat Press (NHP) and machine sections, it is done randomly, not in accordance with the export schedule that determines the plan. This causes the process to not run smoothly because there are many Based on the information that the author has collected in the field, that the discrepancy between the production plan target and the production realization is caused by delays in the procurement of raw materials and the inaccuracy of production process planning between the production schedule and the available raw materials. LITERATURE REVIEW ManagementLogistics According to Irawan et al. , logistics management is a series of decisions to manage goods optimally starting from planning needs, procurement or collection, moving, storing, to delivering distribution of goods to customers. Internal Control According to Mulyadi . internal control includes organizational structure, methods and measures that are coordinated to protect organizational assets, check the accuracy and reliability of accounting data, encourage efficiency and encourage compliance with management policies.

Data collection technique In an effort to obtain the data and information needed by researchers in this study, data collection activities use several techniques as follows: Observational Study Observation is a data collection technique by means of direct observation of the research object, namely by the researcher seeing and working directly at PT. Hogy Indonesia Cibitung. Questionnaire Method A questionnaire is a data collection technique that is done by giving a set of written questions or statements to respondents to be answered. Researchers use a Likert scale. Sampling Techniques The sampling technique used in this study is using a purposive sampling approach. According to Sugiyono, purposive sampling is a sampling technique with certain considerations. The criteria used as samples in this study are employees starting from leaders as policy makers, to subordinates who know and are directly involved in production. Data Analysis Techniques The data analysis method in this study is a study that uses quantitative descriptive. The results of the data collection are then processed so that the information that occurs is easier to interpret and further analyzed in accordance with the form of discussion analysis techniques used. There are two important things in the questionnaire, namely, validity and reliability. An instrument can be declared valid if it can measure what is desired and can reveal data from the variables that have been studied accurately. La Ode Sabaruddin (The Influence of Internal Control of Raw Material Inventory and ProductionA) Jurnal Logistik Indonesia Vol. No. April 2024, pp. E-ISSN 2621-6442 RESEARCH RESULTS AND DISCUSSION Validity Test According to Ghazali . "Validity testing is used to measure the validity of a questionnaire. The criteria for determining the validity of a questionnaire are as follows: If r count > r table then the statement is declared valid. If r count < r table then the statement is declared invalid. Table 1. Validity Test Results Reliability Test Reliability test in this study was used to determine whether the data collection tool showed a level of accuracy, level of accuracy, stability or consistency in revealing certain symptoms. Alpha values 80 - 1. 0 are categorized as good reliability, values 0. 60 - 0. 79 are categorized as acceptable reliability and if the alpha is less than 0. 60 it is categorized as poor reliability. The results of the reliability test show that the Cronbach's Alpha value for the Internal Control of Raw Material Inventory (X. variable is 0. Production Process Planning (X. 731, and Production Process Smoothness (Y) is 0. According to the criteria, each value of the variable is greater than 0. 60, so the results of the distributed questionnaire have a good level of reliability, or in other words the data from the distributed questionnaire is reliable or can be trusted. Normality Test According to Yuwanto and Halim . "the normality test is used to determine whether the sample from the population is normally distributed or not. " In this normality test, the Liliefors test is used by looking at the significant value in Kolmogorov-Smirnov. The testing criteria are as follows If the significance Ou 0. 05 then the data is normally distributed. If the significance O 0. 05 then the data is not normally distributed.
