Abstract

Many types of hearing devices are known, namely headsets, headphones, earphones, handsfree, etc. Headphones are simple hearing aid accessories used for listening and have the best sound quality because they are designed for audio-only. Headphone design is evolving, and one of them can be found in a unique wooden headphone design. Wood is an environmentally friendly material and has an interesting motif. Many headphone users are dominated by millennials, including women in Indonesia, who mostly use the hijab. However, there are not many headphone products designed specifically for women with hijab. This study aims to redesign wood-based headphones for hijab-wearing women based on customer requirements using HOQ. Headphone product design and development is carried out in a mixed product-driven and customer-driven manner. The type of research used is qualitative and quantitative research. Qualitative research through literature studies, preliminary studies, and interviews, while quantitative analysis is based on online questionnaires. In this study, the population was Muslim female students wearing the hijab at Jenderal Sudirman University. The sample used in this study was 150 respondents taken using purposive sampling, and the data collection method was using an online questionnaire. The data analysis used is validation and reliability tests on questionnaires, preparation of HOQ, and design drawings using SolidWorks. The results of this study indicate that product-driven is the addition of small speakers. At the same time, customer-driven (based on the order of technical response from most important) consists of the total cost of production, wood materials, headphones with on-ear type, wireless, and volume buttons.. Keywords: product design, HOQ, mixed product-driven and customer-driven

Abstract

Determining the optimal route is very important in distribution of goods or services, because it can reduce costs and time. CV. Al-Zaman is a company that distributes urea fertilizer in Sumbawa Regency. So far, the company has never determined the shortest route in fertilizer distribution. This research will analyze the determination of the shortest route of distribution of fertilizer by CV. Al-Zaman, whose distribution route was previously modeled into the Vehicle Routing Problem (VRP) model, then the model was solved using the Saving Matrix method in determining the shortest route. So far, the distribution process is based on the driver's experience without analyzing the shortest route first. The distribution is carried out by 15 vehicle fleets with a capacity of 10 tons. The distribution process carried out by the vehicle fleet starts from the warehouse to all destination stores (vertex) and then returns to the warehouse. The results of the analysis using the Saving Matrix method and the VRP model resulted in savings of 75.1 km from the routes that have been used by the company.

Abstract

Forecasting needs to be done to predict conditions in the future so that they can prepare the required resources. PT XYZ is a manufacturer of veterinary drugs with one of its products being probiotics with a size of 2kg whole research problems being studied. Demand for probiotic products fluctuated so that forecasting was needed to predict the number of products in the future period. This study aims to compare demand forecasting with forecasting methods on the Time Series Forecasting Model and determine the best forecasting method. Forecasting methods used are Moving Average, Weighted Moving Average, Exponential Smoothing, and Trend Linear. Based on the error measurements that have been made, the Trend Linear method gives the Mean Square Error, Root Mean Square Error and Mean Percentage values smaller than other methods. Meanwhile, the error measurement based on the Mean Absolute Deviation and Mean Absolute Percentage Error, the Exponential Smoothing method with α = 0.5 gives a smaller value than other methods. However, in the verification of forecasting based on tracking signals, the results show that the Linear Trend method is more predictive and gives closer to actual results than the Exponential Smoothing method with α = 0.5. Therefore, the best forecasting method chosen is the Linear Trend method. The results of forecasting the demand for 2kg probiotic products for the next period show an increase in demand. The results of this study are expected to provide recommendations for companies to determine policies to prepare to fulfill demand in the coming period.

Abstract

The problem that often occurs in production target are not achieved is breakdown engine. Machines are the core of production. As is the case UMKM Marrone is a home industry for making brownies that uses machines as foundation of its production. One of the machines used is steamer ks-601. Steamer machine is a machine used to steam a brownies. The damage that occurs to the steamer engine is due to lack of maintenance, causing the steamer engine performance to not be optimal. The methods used to reduce engine damage are Overall Equipment Effectiveness, six big losses, and Failure Mode and Effect Analysis. OEE aims to improve the performance of a device. Six big losses are six losses caused by the use of ineffective equipment. FMEA is a factor that affects failure with the aim of obtaining factors that require further treatment. The results of the application of OEE found that the average calculation of the OEE of the steamer was 82.19%, still below the JIPM standard, which was 85. Then based on the six big losses, the breakdown losses were 6.08%, set up & adjustment losses were 5.21%, idling minor & stoppage losses were 21.42%, reduced speed losses were 1.48%, process defect losses were 5.04%, and reduced yield 0%. Analysis using the FMEA method shows that the highest RPN is at the turn of the fire adjust switch 175. Then the proposed improvement is carried out using the automatic maintenance method with the CILT stage.
