Abstract

This study aims to evaluate and improve book inventory management at Al-Madinah Bookstore through the application of ABC and VED analysis methods. The ABC method is used to group books based on sales contribution and frequency of use, thus prioritizing the management of the most valuable books. Meanwhile, the VED method is used to classify books based on their level of importance for the continuity of store operations, namely Vital (V), Essential (E), and Desirable (D). This study uses a qualitative approach with descriptive methods to understand the phenomena in the field, while the data is presented and analyzed quantitatively to provide a statistical overview. The analysis results show that the ABC category is divided into 29% category A, 33% category B, and 37% category C, while the VED classification shows 10% of books are Vital, 63% Essential, and 27% Desirable. The ABC method helps prioritize stock control based on sales value, while VED ensures the availability of vital books based on user importance. The synergistic use of these two methods has proven effective in optimizing inventory, minimizing storage costs, and reducing the risk of shortages of important books, thus supporting the Books tore's business sustainability.

Abstract

Construction project delay is a condition where the execution of work does not proceed according to the agreed schedule. The construction project of Norfa Husada Mother and Child Hospital experienced delays impacting costs and operational time. This study aims to identify the factors causing delays, determine the most dominant factors, and formulate preventive measures. The method used was a questionnaire distribution to 30 respondents directly involved in the project, including contractors, consultants, and project owners. Data were analyzed using descriptive statistics (Mean Rank) with SPSS software. The results show that the Planning Factor is the most dominant cause, specifically due to design changes (redesign) and changes in the scope of work, with a mean value of 1.97. The second dominant factor is the Execution Factor, particularly regarding poor work sequence planning, with a mean value of 1.90. Based on these results, the main strategies to prevent delays include maturing the design planning before construction begins, strengthening coordination between the owner and contractor regarding scope changes, and establishing a more structured method of execution (SOP) in the field.

Abstract

Industrial asset maintenance management is a determining factor in ensuring operational continuity and output quality in the rubber processing manufacturing sector. This report examines the effectiveness of Slab Cutter machine maintenance at PT Bridgestone Sumatra Rubber Estate (BSRE) based on observations conducted during an Industrial Internship (Practical Work Program). The background of this study is grounded in the critical role of the Slab Cutter machine as an initial processing unit that reduces the dimensions of raw rubber slabs into uniform pieces in order to optimize subsequent milling and drying processes. Disruptions to this machine often result in significant downtime and irregular rubber particle sizes, which ultimately reduce energy efficiency and daily productivity. The main objective of this observation is to evaluate the preventive maintenance procedures implemented, identify the root causes of mechanical failures, and analyze their impact on the consistency of crumb rubber quality. Through the application of a qualitative field observation method, it was found that synchronization between routine cleaning, bearing lubrication, and blade sharpening was able to reduce operational failures by more than 75%. The conclusion of this study emphasizes that a reliability-based preventive maintenance strategy not only extends the service life of the machine but is also a fundamental prerequisite for achieving sustainable production efficiency targets within the Bridgestone industrial environment. This report recommends the adoption of a data-based monitoring system to detect early component wear in order to minimize emergency repair costs.

Abstract

This report presents the results of a field observation on the strategic role of the prebreaker machine in improving the quality of crumb rubber of the Standard Indonesian Rubber 20 (SIR 20) type at PT Bridgestone Sumatra Rubber Estate. The background of this observation is based on the complexity of processing raw rubber materials (Bokar), which are often contaminated by organic and inorganic materials that can reduce the physical integrity of tire products. The main objective of the observation is to evaluate the mechanical effectiveness of the prebreaker machine in reducing material size, improving contaminant removal efficiency, and preparing the rubber structure for optimal drying stages. The methods applied include participatory observation on the wet processing line, technical sampling, and comparative analysis of quality control laboratory data during the fieldwork practice period. The results indicate that the use of the prebreaker machine significantly reduces dirt content to below the threshold of 0.16% in accordance with SNI 1903:2011 standards and minimizes the formation of white spot defects through improved crumb homogeneity. The conclusion of this study confirms that optimizing blade configuration and rotational speed of the prebreaker machine is a key determinant in producing raw rubber that meets the technical specifications of the global automotive industry, while also supporting energy efficiency in subsequent production stages.
