Background:The rapid industrial development requires companies, especially those engaged in manufacturing, to keep growing and compete to maintain their business. Generally, companies want a short work time to meet production targets and increase profitablity. However, some small and medium enterprises tend to overlook the time standards in their production activities, which causes time and labor waste. This research was conducted to determine the standard time and provide recommendations for achieving the balance of assembly lines. Methods: This study used work time measurement techniques using the time study method with stopwatch. Primary data collection is carried out directly to workers at assembly company. Data is processed by testing data uniformity and data adequacy. Furthermore, the data is used to determine the rating factor, normal time, standard time, and the recommended balance of assembly lines. Results: The results showed that the measurement of working time had a significant impact on the effectiveness and efficiency of production activities by reducing costs for workers by 6.67% and working time to 1.45 seconds faster, as well as achieving the amount of production exceeding the production target. Conclusion: Working time measurement techniques with the time study method using stopwatch can be further investigated and applied to both large industries and small and medium enterprises.

Inventory recording must be done by the company to find out the available stock, so that the company can know when to order goods from the supplier. With the existence of a good inventory system planning, it will be easier for the company to carry out the planned and controlled in and out of the goods process. A distributor of chemicals in recording and inventorying raw materials is still very simple resulting in many products being expired. The purpose of this research is to help companies systematically, precisely and accurately in inventory data collection to reduce expired products. By designing a raw material inventory information system using Visual Studio 2010 programming language and SQL Server 2008 R2 database, then the report form is generated using the Crystal Report 2010 version version. 13.02. With the new information system is expected to be able to provide inventory reports quickly and accurately, and can notify when there are raw materials that will be expired. With the existence of a database based on SQL server, each user will be more effective at work.

Quality control of a product must be considered by all manufacturing companies to maintain product quality. One of the manufacturers of solid drug makers in the city of Medan has problems in the process of packaging/stripping. In the stripping process, there are four types of defects in X solid medicinal products that are leaky / deflated, the packaging is bad, not filled, and in the packaging, the contents are broken. To minimize defective products researchers used the Six Sigma and TRIZ methods. This study aims to determine the value of Defects Per Million Opportunities (DPMO) and sigma level and identify the risk of failure that occurs with the Failure Mode and Effects Analysis method (FMEA) and the Theory of Inventive Problem Solving (TRIZ) method as problem solvers. The result of the value of sigma level before improvement around 3.61 with the possibility of defects approximately 16981 for a million processes. Then, after improving the sigma value to 4.06 with the possibility of a process failure of 1547. The proposed improvements are training or socialization, carry out routine machine maintenance and to give the warning to monitor the performance of each operator.

Competition between companies is very high resulting in companies having to implement production plans so that productivity does not decrease. This is the case with palm oil mills which often experience engine failure resulting in reduced productivity in the company. To examine the problem, it is necessary to measure productivity in the company and design proposals that must be done by the company. In the past data, the company experienced a total productivity index of 71.77% so it is necessary to do a design of engine maintenance proposals so that the time of stagnation can be reduced and the productivity index can increase. After the productivity index is implemented, the lowest total productivity index increases to 161.97% after doing maintenance design, the productivity of the company can increase by 50%.
