<![CDATA[Home indutri batik tulis Jetis, kabupaten Sidoarjo yang merupakan beberapa home industry batik. Tenaga kerja membatik masih mengalami keluhan rasa sakit pada otot tulang rangka pada lengan. Keluhan itu biasa disebut muscoluskeletal disorder (MSDs). Penelitian ini dilakukan pada 15 orang tenaga kerja membatik. Hal tu sebagai besar populasi sekaligus besar sampel peneltian ini. Data primer diambil menggukan angket. Data sekunder diambail melalui wawancara dan observasi. Data primer dianalisis secara deskriptif kualitatif komparatif. Kesimpulan, bahwa keluhan rasa sakit dominan rasa sakit pada lengan atas kanan tenaga kerja membatik sebesar (53,3 %), keluhan rasa sakit itu merupakan musculuskeletal disorder pada lengan atas kanan yang belum menggunakan alat membatik ergonomis. Saran, perlu dibuatkan dengan merancang ulang (redesain) alat membatik berupa canting yang sesuai antropometri tangan dan lengan kanan pembantik. Hal itu agar MSDs lengan atas kanan pembatik menjadi nyaman atau tidak mengeluh rasa sakit.]]>

<![CDATA[Distribution channels have an important meaning for achieving company success in the field of marketing so that company management is required to always be responsive and able to adapt to environmental changes. Input and output data processing is done by giving weights to the input and output using the DEA CCR primal model by maximizing the input-oriented-based objective function. The results of processing the efficiency scale show the relative efficiency level of the scale of each DMU in the company. The efficiency scale is obtained through the formulation of the DEA CCR primal model between each DMU input and output. If the DMU gets an input and output efficiency value of less than 100%, then the DMU is said to be relatively inefficient. Meanwhile, if the efficient value is equal to 100%, then the DMU is said to be relatively efficient. Of the 5 distribution cities, Sidoarjo, PaluKendari, Bandung and Lamongan which were analyzed, there were 2 cities that were inefficient or experiencing waste in their input and output variables, so the company needed to reorganize the level of use of inputs and outputs it achieved and utilize them optimally to get output that is optimal. targeted.]]>

<![CDATA[The existence of a ship project carried out with a tender system by the LPSE allows all shipyard industries to bid on the project, this causes the chances of winning to become smaller, the determination of the tender price greatly determines the size of the profit that can be obtained and the percentage of the possibility of winning the project in a shipping industry. Therefore, the strategy of determining the bid price is very important. The statistical method used is multi discrete distribution, and multi normal distribution, while the bidding model uses Friedman (1956) and Ackoff & Sasieni (1968) models. The results obtained the best bid price strategy to win an auction or tender is the model that produces the lowest optimum mark-up, namely the Friedman model with multi normal distribution, while for Ackoff & Sasieni it produces a higher bid than the Friedman model except in certain company conditions.]]>

<![CDATA[Maintenance activities are generally considered as supporting activities in the production process. However, this activity is very important because it contributes directly to the smooth running of the production process and productivity. PT. XYZ is a company engaged in mass media or newspapers since September 8, 2015. In the newspaper production process, PT. XYZ experienced delays in the production process due to damage to the component parts of the printing machine, in which the Offset printing machine is the core printing machine that is always used to print newspapers. Based on data on the frequency of damage during 2020 which was obtained from observations and interviews with operators, damage to machine components for 1 year on the offset printing machine counted 73 times that it was damaged. Thus making the machine stop operating from the effective working time of the machine, which is 264 days/year. This is due to the unavailability of a machine maintenance schedule because the company is still implementing a breakdown maintenance system. Thus the researcher aims to calculate the value of the identified critical components and calculate the effective time of machine operation for scheduling replacement of critical components of offset printing machines using the Reliability Centered Maintenance method. Based on the results of data processing using the Reliability Centered Maintenance method, the contactor component is determined as a critical component where the value of the Risk Priority Number is 72 with an average checking time of 11,250 minutes and component replacement time of 7 times/year. For this reason, it can be concluded that the contactor is a critical component with a damage value of 72 and the scheduling time for component replacement is 7 times in 1 year.]]>

<![CDATA[Determination of hazard identification and risk assessment on the company can not be separated from the calculation of the cost budget. The aim is to provide recommendations and calculate the profit rate using the Benefit Cost Analysis (BCA) method so that the company will more easily determine the most appropriate and needed alternative in the company. From the incremental analysis calculation, an alternative solution and value obtained from BCA are gas detector H2S B / C ratio 1.14, crane certification B / C ratio 3.66, welding helmet B / C ratio value 5.53, wire rope B / C ratio value of 5.19, O2 detector value of B / C ratio 6.11, small handtruck value of B / C ratio 18.1, fire dry chemical powder B / C ratio value of 22.27, N2 gas detector value of ratio B / C 1.53.]]>

<![CDATA[The many types of production of goods in a company spearhead the progress of this company in industrial competition in Indonesia, the variety of types of products and large production capacity makes this company need a large number of employees to balance the variety and production capacity. This large number of employees creates its own problems, one of the problems is employee performance appraisal, employee performance appraisal in this company is only centered on the highest supervisor's consideration in one section. From that problem, the researcher wants to solve the problem using the Balanced Score Card (BSC) method by using the determination and weighting of Key Performance Indicators (KPI). The final result of the research conducted at PT Alam Jaya Primanusa in May 2018 the results of the following employee achievement grades and categories: Average material value: 76.65 Fair category, Operator's average value: 85.51 Good category, Average value - Selector section average: 89.79 Good category, Packer section average value: 94.98 Good category, Values ​​in each of these sections become the basis for calculations for all injection division production, so conclusions are drawn for the final value and achievement category of all injection division production the value of 83.37 in the Fair category.]]>

<![CDATA[In the world of automotive innovation is not just about products, but services are also not less important always to be developed. Especially as it is today, people tend to like fast service but does not neglect the quality of the services provided. In this study using Micromotion Study, where technicians will be recorded every movement while using the old method of doing improvements to then be processed in order to generate new working methods that are more effective and efficient. Data retrieval is done by as much as 30 times on each experiment that is using the old methods and the new methods being used, the technicians then processed using computer software be Paired T-Test then the average productivity for the old method was 38.03 seconds/unit. Whereas with the new method have average 25.47 minutes/units, so that an increase in as much as 12.27 min/units or of 32.24%. With productivity increases, then the unit enters the vehicle servicing technicians are carried out can also be increased. So a new method that is already done in the workshop workable Nissan Ahmad Yani Surabaya to further accelerate the servicing work, and can increase the unit entry service.]]>
