Abstract

Cigarette packs are rectangular packages made mostly of cardboard containing cigarettes. Packaging is designed from aluminum foil, paper or flavor-protecting plastic and sealed with clear, airtight plastic film. Production process at CV. Langgeng Jaya has 2 types and they are still very inefficient. So, looking at this problem, a proposal is given to innovate a cigarette tongue printing machine to make the cigarette tongue printing machine more efficient and speed up the production process. Innovation: The cigarette tongue molding machine is designed using dimensions from anthropometric calculations and the 50th percentile of workers, so that the height of the material support is 103.75 cm, determines the material entry route of 69.5 cm, and determines the height of the panel box of 93.5 cm. Machine trials must be carried out to determine the difference in output after designing the machine innovation and before the design is carried out. The resulting output must be compared before the innovative design of the cigarette tongue machine is carried out and after the design is carried out. The output produced before the design was carried out was 192, after the innovative design of the cigarette tongue printing machine was carried out, it was 320 kg a day. The increase in productivity after designing the innovative cigarette tongue printing machine was 66%, which means it was successful.

Abstract

This research discusses the design of an ergonomic oyster mushroom baglog pressing tool which aims to increase work productivity in Pak Heru's home oyster mushroom industry and reduce the risk of muscle injury. Workers' muscle injuries can occur during the baglog pressing process which is carried out manually in a bent sitting position. It is hoped that the ergonomic design of this tool will speed up baglog pressing time and increase production efficiency. To determine the risk of muscle injury, the study used Nordic Body Map (NBM) and Rapid Entire Body Assessment (REBA) measurements. And the House of Quality (HOQ) method is also used to determine customer needs and create new products. The trial results of designing an ergonomic oyster mushroom baglog peeler showed that work productivity increased. The research results show that baglog pressing machines can increase productivity significantly compared to previous processes carried out manually. After use of the designed device, there is a low level of risk of muscle injury, according to analyzes using NBM and REBA. Apart from that, the costs for making baglog and oyster mushroom pressing equipment have also been calculated. With a production output of 60 baglogs per hour and 420 baglogs per day, the ergonomic baglog pressing machine increases work productivity and reduces the risk of muscle injury.

Abstract

Abstract UD Dua Saudara is a company engaged in the food industry, namely krecek crackers, the krecek cracker industry is owned by Mr. Lukman, located in Bodor Village, Pace District, Nganjuk Regency. The production process of making krecek crackers at UD Dua Saudara experiences obstacles, especially during the process of cutting krecek crackers, which is the main obstacle in the krecek cracker production process. To carry out a fast and efficient cutting process, there are several obstacles such as tools and work techniques that are still traditional, less efficient, and ergonomic, so that during the cutting process it can take longer and the results are not optimal. There is also the result of cutting in an average day - 136 Kg, to be more efficient, a tool redesign is needed that can overcome these problems. And I hope that later the tool can make the cutting process more efficient, ergonomic and can also increase capacity. From these problems, I designed a krecek cutting tool with an ergonomic approach. The results of data collection and processing obtained dimensional results for the tool with the following: to determine the width of the frame using the 95th percentile, namely 45cm, to determine the height of the tool with the 95th percentile, namely 60cm, to determine the Grip handle using the 95th percentile, namely 5cm.
