Abstract

A construction project is a form of activity that lasts for a limited period of time, with certain resources, where the process requires a technique to be used, namely management, planning, scheduling to control. It is not uncommon for construction projects to experience delays in completing the completion time, so that many losses occur, especially in time and costs. With this fierce competition, timely completion of projects is a top priority for construction companies. The purpose of this study is to evaluate the time of scheduling for project completion using the CPM method on the grounds that the shape of the network or network planning can be identified along with the activities that are on the critical path, and can also be known for a more efficient time in carrying out this project. Based on network planning analysis using the CPM method, a series of work activities were obtained that were included in the critical path and the evaluation results showed that the project could be completed in 668 days and then accelerated using the CPM method again, so the project could be accelerated to 545 days, so that the percentage of time efficiency after crashing is 18.42%, with a total cost of IDR 176,557,549,469.00 with a percentage of cost efficiency after crashing is 0.03%.

Abstract

UKM (Small-Medium Business) Panggon Ngombe is one of the Small-Medium Businesses in Medan that produces Beverages. The processed product from UKM Panggon Ngombe is Boba Drink. UKM Panggon Ngombe has problems in marketing their products; one of the reasons is the unattractive product packaging and still not following customer needs. This study aimed to produce Kansei words that were priorities for beverage packaging improvements, to determine the importance of items affected consumer tastes, and to produce packaging category specifications and beverage packaging designs by using the Kansei Engineering method. Kansei Engineering is defined as a methodology to translate human psychological processes towards the expected product design, by defining consumers' expectations identified through Kansei words into product design. The sample used in the study used a survey method, it was a way of taking a sample with a questionnaire as a research tool in a population, and only 100 respondents were studied, so the conclusions showed were limited to objects. The results of the study produced Kansei words luxury, informative, aesthetic appearance, durable, practical, attractive, and hygienic. The importance level of the items obtained 7 Kansei words for bottle packaging, 6 Kansei words for plastic packaging materials, 7 Kansei words for brown and black packaging colors, 6 Kansei words for 600 ml packaging size, 7 Kansei words for packaging information, 7 Kansei words for circle logo shape, 7 Kansei words for comic san MS writing type, 7 Kansei words for yellow and white packaging writing colors, and 6 Kansei words for boba images on packaging. Specifications for beverage packaging in the bottles form with plastic packaging materials, brown and black packaging colors, packaging sizes 600 ml, yellow and white writing colors, circle logo shape, product information, and boba picture.

Abstract

UD. Sofa Bandar Tinggi is an UMKM in the manufacturing sector with sofa production. In producing sofas in the production process there is still waste. The wastage that occurred in the last year was as much as 17 sets of overproduction, 17 sets of unnecessary inventory, 22 sets of defects and 45 minutes of waiting time. Therefore, it is necessary to identify waste and analyze the causes of this waste to increase productivity by implementing lean manufacturing in the sofa production process using value stream mapping to determine product flow and information flow that support other activities and also to eliminate waste and find the causes of this waste by fishbone diagrams. Based on the current value stream mapping results, the lead time is 109.63 minutes, the value added is 94.21 minutes. After the process activity mapping was carried out, the current stream mapping future state results showed that the lead time decreased to 98.26 minutes. And also the translation of a problem from the fishbone diagram, namely the man factor (lack of discipline, low skill of workers), measurement (repeated wood cutting), method (uneven wood pieces), material (inappropriate wood thickness). The recommendations for improvement to minimize waste are in the form of Standard Operation Procedures and implementing 5S.

Abstract

The study analyzed the effect of price, product, and service quality on customer satisfaction at PT. Jalur Nugraha Ekakurir (JNE) Tebing Tinggi. This research was a quantitative descriptive study with data analysis techniques used, namely multiple linear regression and hypothesis testing (t-test and f test). This research was conducted at PT. Jalur Nugraha Ekakurir (JNE) Tebing Tinggi. On Gen. Sudirman street No.397 Medan-Tebing Tinggi, it was held on 12 December 2020 to 12 February 2021. The data collection method used a questionnaire and documentation. The results of multiple linear regression analysis obtained Y=6.226+0.085X1+0.244X2+0.184X3+e. The results showed that the Price had no positive and significant effect on Consumer Satisfaction at PT. JNE Tebing Tinggi indicated by the value of t count (0.873) t table (1.984) meaning that the Price had no significant effect on Consumer Satisfaction, so H1 was rejected. The product had no positive and significant effect on Consumer Satisfaction as indicated by the t value (1.975) 1 table (1.984), meaning that the product had no significant effect on Consumer Satisfaction, so H2 was rejected. Service Quality had a positive and significant effect on Consumer Satisfaction as indicated by the value of t count (3.477) t table (1.984), meaning that Service Quality had a significant effect on Consumer Satisfaction, so H3 was accepted. Price, Product, and Service Quality together had a positive and significant effect on Consumer Satisfaction.
