Abstract

Water for an industry is a supporting material for both direct and indirect activities to support several systems. Requirements for the quality of water used in industry vary depending on its intended use. Water that comes from nature generally does not meet the necessary requirements so it must undergo a processing process first. Raw water sources play a very important role in the clean water industry. Raw water is the beginning of a process in the supply and treatment of clean water. Water Treatment Plant (WTP) or Water Treatment Plant (IPA) is a system/facility that functions to treat water from contaminated raw (influent) water to obtain the desired water quality treatment according to quality standards. The purpose of this study was to determine the effect of treated water quality and backwash effectiveness by comparing the values of chemical and physical parameters before and after the backwash process in the filtration process unit of a clean water treatment plant. After conducting the tests, it was concluded that the backwash process is very effective in maximizing the performance of a filtration process unit. The effective value of acidity (pH) is (0-5)%, hardness and turbidity is (40-50)%, total dissolved solid (TDS) is (5-10)% and conductivity is (10-20)%. This also shows that the quality of the water tested has met the quality standards in accordance with Permenkes No. 492 of 2010.

Abstract

Along with population growth in Indonesia which continues to increase, natural resources (SDA) experience a decrease in availability (energy crisis). Steps that can be taken to overcome e the energy crisis is to optimize the use of biomass energy as an alternative fuel. One of them is to take advantage of palm fronds and shell waste produced by PT. Perkebunan Nusantara VII Unit Bekri as charcoal briquettes. The process of making briquettes includes drying, carbonization, grinding, screening, and printing. The composition of the briquette raw material mixture consists of five variations, namely V1, V2, V3, V4, and V5. The purpose of this study was to analyze the quality of the briquettes based on testing the proximate value (moisture content, volatile matter content, ash content, and bound carbon content), calorific value, and the burning rate briquettes. The best results for the quality of briquettes from the use of waste palm fronds and shells were obtained in the V5 variation (50% fronds, 40% shells, and 1% adhesive), with a moisture content of 3,65% (SNI 8), volatile matter content of 25,30% (SNI 15), ash content of 6,68% (SNI 8), bound carbon content of 68,03%, calorific value of 6.281 (SNI 5.000), and burning rate of 0,00117 gr/s.

Abstract

In 2020 PT. X produces approximately 220 thousand packaging, this causes the paper raw materials used to exceed the maximum limit or exceed the insheet determined by the company. So that there is a loss to the company, both in terms of material and time. There are 3 types of waste or damaged products that are most dominantly found using lean manufacturing methods. The three  most dominant wastes are excess insheet, non-standard color and excess glue. The application of lean manufacturing is expected to reduce waste in 2020 and maximize the profits obtained. In implementing lean manufacturing, it is supported by using value stream mapping methods  and process activity mapping which is expected to get factors that cause waste. Waste that occurred in 2020 averaged 7.82%, greater than the standard set by the company with an average of 5%.

Abstract

Yogurt is a dairy product made through a fermentation process. Currently, yogurt packaging uses bottle-shaped plastic material. The current problem with yogurt packaging is that the visual image of the packaging, packaging shape, material thickness, packaging size and completeness of the packaging label is still low, so it is considered that it does not meet customer needs. Currently, yogurt packaging uses bottle-shaped plastic material. The problem of yogurt packaging is that the visual image of the packaging, packaging shape, material thickness, packaging size and completeness of the packaging label is still low, so it is considered that it does not meet customer needs. This research aims to identify a list of customer needs, a list of technical characteristics, directions of improvement, and the priority of technical characteristics of Yogurt product packaging. The research methodology uses the Quality Function Deployment (QFD) technique with the House of Quality (HOQ) matrix. The research generates 5 customer needs which were interpretated into 7 technical characteristics with directions for improvement, namely increased material thickness, fixed packaging volume size, reduced packaging length, reduced packaging width, reduced packaging height, improved visual image design, and increased label component completeness. The House of Quality produces a priority order of improvement, with the weight of importance of each technical characteristic, namely packaging length (90), packaging width (90), packaging height (90), packaging volume size (60), visual image size (60), completeness of label components (60), and thickness of packaging material (45).

Abstract

In the current era of global competition, many companies were looking for alternative solutions to compete with other companies in order to survive in competition, one of which is by improving product quality. Product quality can be seen from the number of defective products produced by the   product.   This   study   aimed   to analyze Channel C defective products at PT. Sinarindo Megah Perkasa in order to improve its quality. The data used is Channel C production from 2015-2022 with a total production of 3,860 products with 73 defective products. The results showed that the causes of defective products in Channel C came from several factors which were analyzed using a fishbone diagram including machine, human, environmental, method, and material factors. The DPMO value obtained was 56,735.75 with a sigma level of 3.0828. The recommended improvements were to carry out regular maintenance on the machine, make notes on the size of the machine roll, add people for Quality Control , make Standard Operating Procedures (SOP), and provide detailed training to operators after the SOP is implemented.

Abstract

Skilled construction workers are one of the most important aspects of development. Repetitive work over a short period of time will result in musculoskeletal complaints. One of the tasks performed by skilled construction workers is stirring and carrying cement to ongoing construction, work is carried out for 8 hours a day manually. Therefore, researchers want to identify musculoskeletal complaints in skilled construction workers using the Nordic body map method. Based on the results of the Nordic body map questionnaire, it is known that the parts that experience pain are stiffness in the lower neck, left and right shoulders, waist, left and right hands, left and right knees, and left and right feet. This musculoskeletal complaint is caused by a work position that is bent and done repeatedly. The proposal given is to change the working position, use transport tools, and stretch before transporting cement.
