PERBAIKAN SISTEM KERJA BERDASARKAN ASPEK BIOMEKANIKA DI PT. CRESCO INDONESIA

PT. Cresco Indonesia is one of the companies that concerned in the Japanese slipper sandals industry in West Java, which was established in 1989. In order to responses to demanding costumer, PT. Cresco Indonesia applies ‘make to order’ strategy, so the production process will be carried out if there are any orders from consumers. The company has 13 departments. Based on observations has known that there are 4 departments that have a potential to cause an accidents work, they are the happo department, the shiage department, the quality control department and the packing department. The beginning measurements of RULA and REBA out of four departments show the results of high risk action levels. To improve the situation, work system improvements must be made. This study intends to improve the body's posture and work system currently, so that the design of tools for the movement of baskets in the shiage and quality control departments, grouping and labeling in baskets in the happo department as well as improve the order of the process of lifting goods in the packing department. Work system improvement is carried out using biomechanics theory. The final result of the design shows the value of RULA and REBA of operators is low risk, minimizes the value of defects in the happo department, reduces the activities of finding baskets in the happo department, minimizes the time of movement from the shiage department to the quality control department, improves the way of lifting goods in the packing department and fix up the posture of the operators

Perancangan SOP dan Tata Letak Lantai Produksi Pada LCC Respira V.01 PAPR (Powered Air Purifying Respirator)

<p><strong>The production process of a tool is very important in a manufacturing company, especially in producing medical equipment. The use of medical masks by health workers in handling COVID-19 patients for hours will make medical personnel uncomfortable when wearing them, one of which is congestion. Therefore, the LCC RESPIRA V.01 PAPR (Powered Air Purifying Respirator) was produced, designed by Mr. Ahmad Juang Pratama, who is a lecturer at Al Azhar University Indonesia. In the production of LCC RESPIRA V.01, a standardization of the production process is needed, so that the reliability of the product can be guaranteed. For this reason, the design of the SOP (Standard Operational Procedure) and the layout of the production floor are carried out in the production process of the LCC RESPIRA V.01 tool. The results of this study include the design of a production SOP in which several departments take part in it, namely team leader, head of the production, production operator, research and development department, head of the warehouse, and quality control department. Besides, a production floor layout design is obtained, where the total production floor area is 8.2 x 6.0 m2 with manual and trolley material handling types.</strong></p><p><strong><em>Keywords</em></strong> – <em>C</em><em>ovid-19, </em><em>L</em><em>ayout production floor, </em><em>M</em><em>edical equipment, </em><em>S</em><em>tandard operational procedure</em></p>

DEVELOPMENT AND VALIDATION OF STABILITY-INDICATING RP-UPLC METHOD FOR THE SIMULTANEOUS ESTIMATION OF TEZACAFTOR AND IVACAFTOR IN FORMULATIONS

Objective: Aim of the present research work was to develop a sensitive, rapid and accurate, stability-indicating RP-UPLC method for the simultaneous estimation of tezacaftor and ivacaftor in formulations. Methods: The chromatographic separation of the mixture of tezacaftor and ivacaftor was attained in isocratic method utilizing a mobile phase of 0.1 % orthophosphoric acid and acetonitrile in the proportion of 50:50%v/v utilizing a HSS C18 column which has dimensions of 100×2.1 mm, 1.7 m particle size and the flow rate of 0.3 ml/min. The detection system was monitored at 292 nm wavelength maximum with 1.5 ml injection volume. The present method was validated as per the guidelines given by the ICH for specificity, accuracy, sensitivity, linearity and precision. Results: The retaining time for tezacaftor and ivacaftor were achieved at 1.071 min and 0.530 min, respectively. Tezacaftor, ivacaftor and their combined drug formulation were exposed to thermal, acidic, oxidative, photolytic, and alkaline conditions. The developed method was highly sensitive, rapid, precise and accurate than the earlier reported methods. The total run time was decreased to 2.0 min; hence, the technique was more precise and economical. Stability studies directed for the suitability of the technique for degradation studies of tezacaftor and ivacaftor. Conclusion: The projected method can be utilized for routine analysis in the quality control department in pharmaceutical trades.

Welding defects, Causes and their Remedies: A Review

This review paper looks at the causes of welding defects and their remedies which occur during the welding process. Welding industries in developing countries bearing poor quality and productivity due to the involvement of a number of the process parameter. Even in a completely controlled process, defects in the welding are observed and hence welding process is also known as the process of uncertainty which challenges explanation about the cause of welding defects. In order to identify the welding defect and problem-related to welding, the study is aimed at the research work. This will be beneficial in enhancing the yield of welding. Beside this, standardization (optimization) of process parameter for the entire cycle of manufacturing of the critical part is intended in the proposed work .This review paper also provides the accurate guideline to the quality control department to find welding defects and will help them to analyze defects which are not desired. In this review paper, an attempt has been made to categorise the various welding defects and their root causes of happening.

Design and Fabrication of Automated Work Piece Counting and Sorting using Image Processing

In that logical decision, controls is of two types and are microcontroller and PLC (programmable logical control) .PLC based and microcontroller control based systems are used for automation process for in industries. Since automation is very important for an industry to reduce human effort this project is been developed .In this project a system is been implemented for automated work piece counting and rejection that works using microcontroller linked with image processing concept. These kinds of system are mainly used in Quality Control department to remove scraps. This system is built using Arduino controller and the basic concepts of image processing using MATLAB .The rejected materials are collected in separate bins and are removed as scraps.

Analisis Penerapan Konsep Lean Manufacturing pada Penurunan Defect Knuckle Arm Steering dengan Metode PDCA di PT.PQR

PT. PQR produces casting for automotive products. Based on data from the Quality Control department, there are several products with high defect levels and most of defect products are categorized as scrap that make the company's efficiency decrease. This condition is very detrimental to the company because it will add costs that should not be spent. Therefore, this research is conducted on the causes of defects for finding the solutions. The results of the observation showed that the data during January - March 2017 knuckle arm steering products had a defect rate of 20.04% with macro shrinkage as the biggest contributor. In March-July 2017 improvements were made with the concept of lean manufacturing with the PDCA method. The results of these improvements provide improved quality of knuckle arm steering products so that defects are reduced by 15.01% to 5.03%. Then the cost incurred before improvement is Rp. 2,626,160 and after improvement is Rp 2,224,890
