PT.  Harmony  Toba  Jaya  is  one  of  the  paint  distributor  with  Sikkens  trademark. Companies  choose  direct  communication  with  consumers  workshops  in  their  marketing communications strategy. This is done because of the increasing number of new paint products on the market so we need a strategy that is relevant to the condition that there is a bottom -up with a marketing strategy where marketers sell products directly to end users or workshop. Based on the above conditions need to be processing data analysis using SWOT analysis (Strength,  Weakness, Opportunity and Threat) from Sikkens paint products through questionnaires given to consumers. Based on the results of the questionnaire processing, can be calculated the value of the X axis and Y axis to determine the position of the company. The value of  the X-  and Y-axis respectively is -0.141 and  -0.100 so that the value of the intersection of the axes X and Y are XY (-0.141;  -0.100). From these  results,  the  company  is  located  in  Quadrant  IV  (negative,  negative).  It  is  necessary  to  get attention  because  in  addition  to  the  weakness  of  the  company  there  are  also  threats  from competitors  that  are  very  dangerous.  Therefore,  recommendations  given  strategy  is  Strategy Defense,  meaning  that  the  internal  conditions  of  the  organization  that  are  in  selection  dilemma. Therefore, organizations are advised to use a survival strategy, the performance of internal control so as not to fall. This strategy is maintained while trying to fix ourselves.Keywords: Marketing Strategy, SWOT Analysis, Company Position

Abstract

The cost of production is needed to determine the cost of production of a product. Costs incurred to produce the product must be clear, so that the determination of the cost of production would be appropriate. Imprecision in calculating the cost of production will be misleading in making management decisions. Data collection methods used in this study include: Documentation, Interview, Observation. This study analyzed using qualitative descriptive analysis comparing the theory with actual results of the company. PT MUTIFA in determining the cost of production using the full costing method. PT MUTIFA in determining the cost of production, all costs incurred are treated as production costs, both the cost of major raw materials, cost of auxiliary materials, packaging materials costs and production overhead. Classification of production costs in accordance with the theory that exists is composed of material costs, labor costs and production overhead costs. Total production cost per month of each element calculation the average monthly cost is Rp. 73.111.118,260,- and the average number of finished products Paracetamol tablet 500 mg tablet is as much 566,666.67 per month.

Abstract

Along with the development of technological products that can provide comfort and convenience for human life which will depend on the innovation of more complex product functions for consumers that will continue to be used, therefore it is necessary to design lightweight brick molds that are ergonomic and able to meet customer demands. The design of the lightweight brick mold was carried out using the Pahl and Beitz method by applying the REBA (Rapid Entire Body Assessment) method for proposed improvements by evaluating the worker's overall posture. The aim of this research is to produce an ergonomic design that is able to meet every customer request. The results of the research showed that measurements of work posture carried out by light brick workers had to take corrective action because it showed level 10, which means it was at level 4 (dangerous conditions). By reducing dangerous angles on body parts, a better working body posture is obtained with a REBA score of 3 which is included in risk level 2 (Low risk) based on worker anthropometric processing where each data is sufficient and uniform, so that a lightweight brick mold design can be produced. reduces the risk of injury to musculoskeletal disorders for workers with dimensions of mold length 100 cm, width 51.27 cm, mold height 60 cm, mold handle length 29 cm, mold handle width 9 cm

Abstract

As well as at PT. Perkebunan Nusantara IV unit Adolina, it is a company engaged in palm oil processing become semi-finished raw materials, i.e. CPO (Crude Palm Oil) and Kernel core. Similarly on losses on CPO and Kernel core occurred when production process, palm oil factory PTPN IV unit Adolina is very minimize loss as little as possible on CPO and Kernel core occurred. So, the purposes of the study are to find out how big losses on CPO and Kernel core, to increase OER and KER by using Statistical Process Control (SPC) method. Based on the analysis results obtained that, the amount of losses in station of Empty Bunches (X1 = 0.57%), Press (X2 = 0.56%), Nut (X3 = 0.10), Last Sludge (X4 = 0.39), Fibre Cyclone (X5 = 0.26), LTDS (X6 = 0.12), and Claybath (X7 = 0.01). Thus, there are four factors affect the occurrence of losses on CPO and Kernel core, i.e. Human Resources, Machine, and Raw Materials

Abstract

CV. Suka Bersama is an MSME (Micro, Small Medium Enterprises) in plastic straws (pipettes) manufacture. The main materials used in the process of making this pipette are polypropylene and dye which consists of three colors, namely yellow, green, and red. Currently CV. Suka Bersama only used estimates in raw materials purchasing. If the raw materials ran low in the warehouse, then CV. Suka Bersama had to reorder raw materials based on use, so it often had the unavailability and excess stocks in the warehouse. Where there was excess, there would be additional costs, and if there was less, production would be hampered. One way that could be used to overcome this was by applying ordering raw materials using the Economic Order Quantity (EOQ) method which was used to determine the number of orders or purchases that might be made and how many quantities might be ordered. So that the total costs in the sum of ordering and storage costs were a minimum, raw material inventory control and how to apply the economic order method, safety stock reorder point, and total cost in controlling raw material inventory. By calculating the raw material inventory issued by the company was Rp. 4,429,969 while using the EOQ method was Rp. 979,110 of the total cost of raw material inventory was more efficient using the EOQ method with a difference of Rp. 3,450,859.
