Abstract

Polypropylene is the most widely used polymer material in the automotive industry due to its properties such as good rigidity, high melting point, chemical resistance, and easy processability. Polypropylene is usually added with a filler, namely bentonite, to make polypropylene which has better mechanical and thermal properties. The coupling agent is added to improve the adhesion of the matrix with the surface so that the composite component has better durability. To improve the ability of the filler material, bentonite is converted into nanoparticles. Bentonite nanoparticles are expected to have better mechanical, thermal, electrical, and optical properties than particles with micro or macro sizes due to their large surface area. Based on the description above, it is necessary to study the effect of using bentonite nanoparticles with a coupling agent in the form of Maleic Anhydride-g-PP (MAPP) on the tensile strength and thermal properties of polypropylene composites. The variables of this study are the composition variation (weight %) of polypropylene, coupling agent (MAPP), and bentonite nanoparticles of 100:0:0, 95:0:5, 90:5:5, 85:5:10, 92:3:5, and 87:3:10. The method used in this study uses a twin-screw extruder tool with a temperature of 190°C and then tested regarding its tensile strength and thermal properties. The results showed that the addition of nano-bentonite tends to cause an increase in the decomposition temperature of the sample but does not increase the tensile strength of the composite, so it only functions as a polymer composite filler. While based on Differential Scanning Calorimetry (DSC) testing, the enthalpy value decreases with increasing concentration of coupling agent.

Abstract

PT. YZ is currently still not optimal in utilizing the resources it has (input) so that the results (output) produced are not in accordance with the target which results in a decrease in company productivity and so productivity measurements must be carried out in the company. Besides that, at PT. YZ has never conducted a thorough productivity measurement during the production process. Therefore, in this study, productivity measurements were carried out with the aim of knowing the results of measuring productivity levels at PT. YZ, to find out the factors causing a decrease in productivity levels and evaluate productivity against measurement results that have low productivity. The proper method for analyzing these problems is to use the Marvin E Mundel method to measure productivity and the Productivity Evaluation Tree (PET) method is used to evaluate productivity issues. In carrying out processing using this method, it is assisted by the Embarcadero-Dev C ++ Software. Based on the results of research using the Marvin E. Mundel method, it was found that company productivity had decreased, namely that in 2021 total productivity was 1.14 and in 2022 total productivity was 1.13. The cause of the decline in company productivity is that the labor factor is not clearly regulated for sanctions and rewards for the company; the raw material factor is the long distance of delivery from the raw material supplier to the production site; and the energy factor has not yet carried out accurate calculations regarding the use of electricity for the process. Production and machine factors have not yet established a machine maintenance schedule. The evaluation results using the Productivity Evaluation Tree (PET) method show that total productivity has increased; in 2022, total productivity was 1.13, and in 2023, total productivity was 1.15. To increase productivity, this was done by reducing input, namely the number of workers. By reducing the number of workers, productivity increases.

Abstract

In the current era of global competition, many trading companies compete to meet consumer needs. This competition causes the level of demand between companies to fluctuate greatly, resulting in problems in the company's inventory system for goods or products. Inventory problems that often occur in a company include over stock, stock out, underproduction, overproduction, back log, and inventory that is not in line with company targets. This inventory problem is one of the things that must be overcome by controlling mathematically using methods that suit needs. One method that assumes this fluctuating demand used a model Economic Order Quantity (EOQ) Probabilistic. Therefore, this study aims to examine the use of Probabilistic EOQ in controlling company inventory and find out how much influence the use of this model has on company inventory. This study uses the method Systematic Literatur Review or SLR with a qualitative model that combines several literature articles as a reference for the study. The study produced several important notes on the use of the Probabilistic EOQ model. This model aims to optimize total inventory costs with the assumption that demand for products or goods is very fluctuating. This model assumes that the data is normally distributed with a waiting time or lead time as a basis for decision making in calculating optimal inventory. Apart from that, other supporting methods are needed to strengthen calculations in overcoming inventory shortages, such as safety stock or safety supplies and reoder point. The research results show that this method can be used on various types of food and non-food items. Apart from that, this method is considered to be able to reduce total inventory cost or total inventory costs.

Abstract

An information technology system basically includes 3 things, namely hardware such as computers and printers, then software, and also the user or user who controls it, or what is usually called brainware. In the industrial world, information systems are needed to facilitate the work carried out by users. Based on the results of observations at the research location, several problems were found, namely the process of searching for items took a long time due to the location of the items not being well organized and the layout of the shelves in the warehouse being quite confusing. The number of items in the warehouse is also not recorded, making the warehouse manager unable to confirm the number of items in the warehouse. Numbering shelves in the warehouse is also a problem because insufficient lighting makes it difficult for users to find the right shelf in a short time. By designing an information system in the form of a website related to the warehouse inventory system which is connected using WiFi connectivity with the Espduino-32 module which controls the relay to turn on the shelf marker lights when and during the user's search for items. The results obtained from the implementation are that the process of searching for items in the warehouse is easier and can be done in a short time with the shelf number information listed in the search system as well as the indicator lights that will light up during the search process
