Abstract

This study aimed to identify levels of catechins in gambier. The sample used is Gambir taken in the market with differences in terms of color, shape and packaging. Solid Gambir is mashed and added with water until it becomes a paste and then filtered to produce pure gambier extract. Furthermore, it was deposited and dried then crushed and sieved with a size of 60 mesh. Samples were dissolved with ethyl acetate and ethanol in a ratio of 1:10 and then dried and tested for catechin content, tannin content, water solubility and ash content. The results showed that catechin levels in G1 samples were 50.81%, G2 samples were 40.60%, and G3 samples were 30.70% while tannin levels in G1 samples were 11.50, G2 samples were 17.21 and samples G3 of 23.51. The result of the research concluded that there were differences in the amount of catechins in the three study samples. The best catechin levels were found in the G1 sample as much as 50.81%, then the G2 sample as much as 40.60%, and the G3 sample as much as 30.70%. While the tannin content has an inverse amount of concentration than concentrates. The more the amount of katekin in gambier the lower the amount of tannin.

Abstract

PT. Fajar Baizury and Brothers engaged in processing oil palm products. The palm oil plantation industry produces 2 types of products, namely palm oil and palm kernel core. This research is more focused on the palm kernel produced, especially in terms of the quality produced.  The  quality  of  the  resulting  kernel  is  of  course  good  and  some  are  defective. Defective kernel production results can cause problems for the company, because it can be detrimental. So the levels of defects needs to be reduced and controlled so as not to cause harm to the company. Defective kernel produced have three categories, there are moisture, dirt, and broken. The Seven Quality control device are used to reduce the type of disability produced. By using data that has been obtained during field observations and data from bookkeeping results provided by the company, then data processing can be done. The data used in this study is the production data from 2018. So as to reduce the type of defect that the kernel produced.

Abstract

The pharmacy is a place for the taking of drugs available at the Puskesmas Ingin Jaya, where in the process of taking drugs often there is a queue at certain times. This study aims to improve services so as to minimize the average waiting time for taking drugs while waiting in the queue and the service queue system so that the queue does not occur too long. The analytical method used is queuing theory analysis in accordance with the single phase single channel model or M / M / 1 which is applied to the pharmacy Puskesmas Ingin Jaya. The results of research on the process of taking drugs at the pharmacy Puskesmas Ingin Jaya by using queuing theory analysis, namely by calculating the queue model of one service line shows that in the non-rush hour condition, the number of facility lines used by one facility line is good, but not at the hour condition busy at 09.00-10.00, which shows that the longest patient waiting in the queue is 11 people, while the shortest queue is at 11.00-12.00, 9 people. The suggestion in this study is to add one service facility during the peak hour period, namely to become two facilities so that it is expected to optimize the performance of the service in the process of taking drugs.

Abstract

Work posture analysis needs to be done in order to reduce injuries, Musculoskeletal Disorders are one of the injuries that are often experienced by workers in carrying out Manual Material Handling (MMH) activities, namely injuries to muscles, nerves, tendons, bones, joints, cartilage caused by activities work. The purpose of this study was to measure work posture using the OWAS and REBA methods. These results will be used as a reference to provide recommendations for improving working posture at the Sterilizer station. The results of this study indicate that there is no significant difference in evaluating work posture in assessing work posture with the application of OWAS and REBA methods. Only the final score (grand score) is different, this is because the assessment of the assessment category scores on each work element is different based on the method used. Assessment of posture based on the OWAS and REBA methods provides the same conclusion that the level of risk of musculoskeletal disorders is at a high level. This proves that both relevant methods are used to assess at the sterilization station at PT. Karya Tanah Subur.

Abstract

In this study, work observations were carried out using the Work Sampling method. Work Sampling method is used to see employee productivity in completing work. This research is also supported by the spread of the Nordic Standard Quaire Questionnaire (SNQ) to find out complaints experienced by workers. From the results of data processing, it is obtained that the standard time of each Worker / employee in completing their work is, Worker 1 is 60.13 minutes, Worker 2 is 59.236 minutes, Worker 3 is 59.035 minutes, Worker 4 is 60.218 minutes. The average percentage of workers working (productive) is 88.27% and the average percentage of workers doing idle is 11.73%. And from observing the work sampling method, there were 8 workers in the governance & compliance department.

Abstract

Now, industry that is engaged in services has increased, this requires the procurement of services must be able to provide optimal service. The business is needed for the company to remain competitive in other service industries. One of the main factors that greatly influences how services are provided. The quality of production is very dependent on the efficient use of time. Measurement of work time can be seen from the production and operating activities in the company whether efficient or not. The more effective and efficient the employee completes a work cycle, the more productive and the resulting output will be as high. Cut Nyak Dhien Regional Hospital is a company engaged in the field of health supply. Cutnyak Dhien Regional Hospital has one service unit, one of which is the Health BPJS unit, where the SEP card (patient eligibility letter) is prepared in this unit. This SEP will be brought to certain poly-poly. The problem found was that operators had to complete SEP for almost an average of five hundred patients per day. Therefore it is necessary to calculate the work time needed to complete the SEP. One way to measure how much work time is needed by an operator in making an SEP is to calculate the cycle time of the SEP manufacturing process. Cycle time is one way to find out the operator's working time in the technique of measuring work time. Measurements were made directly using stop-hours. The measurement was repeated three times with 10 observations for each operator. The measurement results show that the operator can complete SEP within the normal timeframe of around 50 to 70 seconds per patient.
