Abstract

The distribution of sulfuric acid raw materials is still conducted conventionally and faces challenges regarding the quantity of supply for each product. Therefore, this research was conducted to help create a mathematical model for the distribution of sulfuric acid using the Goal Programming method with the assistance of LINGO 18.0 software. Goal Programming serves to minimize deviations from limits and targets based on priorities in order to maximize profit and achieve the optimal quantity of sulfuric acid in the distribution of sulfuric acid raw materials, as well as to supply several fertilizers containing sulfuric acid. The research results indicate that the annual sales revenue target of 982,937,304 USD was achieved without any deviations. Most of the optimal production targets for products X1 to X8 were also met, with deviation variables showing no shortfall in production quantities for these products. However, for product X2, there remains a production shortfall of 60,096.15 tons to reach the target of 405,823 tons.

Abstract

Queueing issues at an ice cream parlor in Serang City have led to long lines due to having only one service system. The queue problem arises when many customers request service, but the number of servers is limited. One issue is that customers often have to wait in line to be served by the cashier. The aim of this study is to develop strategies to reduce queue length and improve service efficiency. The method used is Discrete Event Simulation, which provides a reliable and measurable approach to model queue variations. This system allows for identifying the best solutions to reduce waiting time and increase service efficiency in the ice cream parlor industry. This study shows that with 30 data replications and using seconds as the time unit, the total queue waiting time is 7,215 seconds with an average of 510.59 seconds. The average waiting number in the queue is 2.2371. The result of 0.95 indicates that resource utilization is close to maximum (close to 1), meaning the resource is almost always in use.

Abstract

Many people choose bottled drinking water because it has been processed and meets drinking water quality standards so it is safe for consumption. Based on data from the Indonesian Bottled Drinking Water Companies Association, in 2014, Indonesians consumed 23.1 billion liters of bottled drinking water, an increase of 11.3 percent compared to 2013 which was only 20.48 billion liters One of the reasons the product does not sell in the market is the weakness of production management, especially the lack of precision in the production process. Constraints that can cause defects in the blowing process include mismatched air pressure or oven settings, which can result in defects such as unmelted bottoms, tilted bottle necks, white bottoms, torn or burst bottles, or bottle shapes that are not as expected. PT. TBK is one of the companies that produces bottled drinking water in 600 ml bottles. Efforts that can be made by the company are to improve product quality through quality control. Six Sigma is a method used for continuous process improvement and enhancement. Research at PT. TBK aims to identify the main factors of product failure during production and analyze the sigma level of 600 ml bottle defects. From the results of the DPMO calculation converted to the Sigma value, a value of 0.79 was obtained with an average DPMO of 1337.39. This means that the 600 ml bottle blowing process produced is above average or has reached the standard.

Abstract

PT XYZ is a company specializing in the bottled tea beverage industry. The company is experiencing quality control challenges, evidenced by a defect rate of 0.9%, which exceeds the target of 0.2%. This study aims to identify the reasons for the high defect rate in tea production and provide recommendations for improvement. Utilizing the Six Sigma approach along with the DMAIC (Define, Measure, Analyze, Improve, and Control) methodology can help maintain product quality by identifying the sources of defects in tea products at PT XYZ. The research identified three main types of defects: insufficient volume, lack of crown, and non-standard temperature. The most prevalent defect was non-standard temperature, accounting for 7,968 defective items (60%). The causes of these defects include human factors such as operator negligence and lack of precision, material factors such as low tea temperature and decreased bottle temperature, method factors like improper and inaccurate inspection methods in the Quality Control Division, machine factors such as low caustic temperature in the washer machine, and environmental factors like high room temperature. Recommended improvements include conducting regular training sessions for operators to enhance their understanding of their work areas, especially in monitoring the production process. Additionally, thorough quality checks should be performed in line with the steps outlined in the work instructions. To reduce defects and errors in packaging machines, regular maintenance is essential to ensure their smooth operation.

Abstract

Activities that are carried out repeatedly over a long period will result in musculoskeletal disorders. As happened, company X focuses on the production of car seats. The results of interviews with workers revealed that they often experienced complaints in the back, neck, feet, and calves. Therefore, this research aims to analyze workers' body posture, especially in the measuring and sewing department, to increase work comfort and productivity using the Rapid Upper Limb Assessment (RULA) method. The research results show that the final score obtained from the measuring position using the RULA method gets the same score, namely 5. This means that the score is at a high level with investigative and corrective actions immediately handled. The body posture involved when measuring a car seat in a less-than-optimal position is (1) bent or flexed neck. This position often puts pressure on the neck muscles to get a better angle, causing muscle fatigue due to long and repetitive work; (2) the worker's back bends forward to access certain parts of the car seat, especially if done in low or difficult-to-reach areas. This position can increase the load on the spine and cause discomfort and even injury to the lower back; (3) raised shoulders, due to the worker measuring the top or accessing a higher area of ​​the car seat which will constantly increase the risk of neck and shoulder muscle tension; (4) the arms are bent and the hands are repetitive, this position occurs due to seat measurements which require repeated use of the hands to mark certain areas.

Abstract

Fibo School is a learning management system product based on Artificial Intelligence technology. Since its launch until now, the number of users of Fibo School products is still very low. The root causes of the low number of users are human resources, products, promotions, and processes and partnerships. One way to overcome these problems is to evaluate and design a proposed business model using the Business Model Canvas. The required data are existing business model data, customer profile data, and business environment data. Evaluation of the existing business model is done by analyzing 7 questions and SWOT analysis to get a proposed strategy. Some of the proposed improvements are focusing its market segmentation to private educational institutions in West Java Province and Special Region of Jakarta, creating materials and learner evaluations according to the curriculum, providing a variety of subscription packages, and building partnerships to help product development and marketing. In addition, a financial simulation was conducted to calculate the financial impact of the proposed business model changes. If an increase of 25 customers can be obtained in the first year after the implementation of the proposed business model, with a 20% increase in sales in the following year, then the business model change will provide an IRR value greater than the MARR of 11.30% and an NPV value greater than zero.

Abstract

Currently the problems being faced by PT. XXX Medan is a biscuit defect that exceeds the standard defect limit desired by the company, namely a maximum of 5%. Based on these conditions, it is necessary to resolve the causes of biscuit defects using the Failure Mode and Effect Analysis (FMEA) method. The results of the Cause and Effect Diagram and FMEA analysis that have been carried out, it is known that the highest RPN value is 320, namely the oven temperature changes causing the biscuits to not be cooked perfectly, so it is necessary to control by checking the cooking temperature parameters on the oven machine display so that they always match the temperature. which are expected. Improvements need to be made to the SOP by establishing a system for checking the machine display every certain time during cooking so that the temperature value does not change. The response to the cause of this failure is continuous maintenance.
