Abstract

The midsole is an inseparable component of the shoe. For this reason, midsole production must be fulfilled so that the needs of shoe manufacturers to produce shoes can be met according to the target. Midsole Jepara factory is one of the work units of PT. X is a company that processes Compound raw materials into Midsole as its main product. ISO 9001:2008 is an international standard for quality management systems. ISO 9001:2008 establishes requirements and recommendations for the design and assessment of a quality management system. It is expected that the products produced from an international quality management system, will be of good quality (standard). Based on this, this study will discuss the quality assurance contained in a manufacturing company to prevent the absence of things that cause product defects. In analyzing the implementation of ISO 9001:2008 used is the analysis of P control maps, fishbone diagrams, and Pareto diagrams. In controlling the midsole products it produces, PT X applies a policy regarding product quality standards, namely using the PDCA (Plan Do Check Action) quality standard.

Abstract

XYZ Village is an industrial village that produces woven fabrics. Failure in the production process is something that must be traced to the cause so that it can be used as a basis for improving product quality. Total Quality Management (TQM) is an approach to running a business that tries to maximize the competitiveness of an organization through continuous improvement of products, services, people, processes, and the environment. This study was conducted to identify potential causes of failure and improve the quality of woven fabrics in the weaving process in XYZ Village with the TQM method approach. Based on the calculations that have been done, it was found that there are two valid variables and two other invalid variables because the value of r-count > r-table, namely the variable color is less bright and the color is mixed. Then the main factors that cause the quality of woven fabrics to decrease and result in production failures on woven fabrics are inappropriate battens and also color spots on woven fabrics.

Abstract

Sounds that are not desired by the listener, where the sound can distract, interfere with activities, or cause danger during daily activities, can be called noise. Noise at a certain level originating from the sound of work tools in the production process can cause comfort and health to be disturbed. The lousy impact that often occurs if a person is exposed to noise for too long is the effect on hearing, which can cause deafness, but this can be controlled by using hearing protection equipment that will determine the amount of compensation value to be received by the surrounding community. The existence of the Landfill, which is often located in the middle of community settlements, has a direct impact, one of which is noise during every working hour of the Landfill's operations. One example of a Landfill that is still active today is the Klotok Landfill which is located in Pojok District, Kediri City. In this research, noise mapping was carried out to determine the pattern of noise distribution that occurs in the work environment. Making a noise contour map due to these activities will use a software called Surfer, which is a simple program to generate noise curves (noise contours) spatially the location of potentially hazardous areas. The result shows that activities at the Klotok Landfill have noise values ??ranging from 40 to 92 dB. The highest noise is in the location around landfill area 3, which is actively operating. The high noise level also can be found in the weighbridge, which is a place for transporting vehicles to pass. Evaluations at points 17, 18, and 19 indicated the need for protective wear, such as earmuffs or setting a break every 1.4, 3.6, and 2.2 hours for area workers.

Abstract

Landfill management in Indonesia is mostly operated by open dumping as well as the Klotok’s Landfill at Klotok Village, Kediri City. This landfill has three lands, and the third landfill is currently actively operating. The pollution is like the occurrence of leaks in leachate storage tanks which is near the Klotok river. That situation can make the leachate enter the river and affect the physicochemical conditions of the water which have an impact on decreasing the diversity and abundance of plankton. The diversity of plankton species in aquatic ecosystems is often used as an indicator to determine the primary productivity of waters and the condition of the aquatic ecosystem, so this research was carried out to determine the diversity of plankton species in the Klotok river, so the quality of the water can be known. This research was conducted in the Klotok River, Kediri City, East Java. Samples were taken upstream of the Klotok River, near the leachate treatment Plant, and downstream of the Klotok River. Samples were taken as much as 21 liters by pouring method. The samples are poured into plankton nets. The result shows that plankton diversity in the water body near Klotok landfill is between 0,49 to 0,67, which indicates that the diversity index according to Shannon-Wiener is 0,49 where the species diversity is low, the number of individual species is low, the ecosystem is unstable, and the waters are degraded.
