SPC (Statistical Process Control) is one of the Lean Manufacturing techniques, but especially Six Sigma, being a method of improving the quality of the manufacturing process, which allows the identification of errors before their production, with the help of which a process can be supervised and when needed, it is possible to carry out an intervention of regulation, respectively of correction of the process, before being nonconformities. The paper presents a study regarding the use of SPC at a company in the automotive field in order to improve the quality of the manufacturing process for a knuckle. Thus, a number of 25 samples were taken, each sample containing a number of 5 pieces. After sampling, a series of techniques and statistical data were used, respectively diagrams and control sheets, which allowed the determination of the process capability by using MiniTab software.

<p><span style="font-size: medium;"><span lang="IN">PT. XYZ is a company engaged in the sport shoe with the marketing areas inside and outside the country. One of the products produced by PT. XYZ is running shoes. The problems faced by the company is not achieving the production targets because many value-added activity not belonging to the waste (waste). For that use lean manufacturing approach to eliminate waste that occurs on in the production line at PT. XYZ. Lean manufacturing methods used is values stream mapping (VSM) to analyze the dominant waste in the manufacturing process. Based on the analysis we found three recommendations for improvement, namely the use of a forklift, the addition operator and addition of machine. Results of evaluation of recommendation is decreased production lead time equal to 8610.62 sec, increasing the value of Process Cycle Efficiency of 21.08%</span><span>.</span></span></p>

PT. Intan Ustrix that's placed at Jl. Raya Roomo No.425, Sekarsore, Roomo, Kec. Manyar, Kabupaten Gresik Indonesia is a company engaged in the paper and cardboard business, and has many machines used in the manufacturing process. The load of the induction motor will make the cost lower, thereby increasing the current cost through the device inside the carton production unit. Fixing the cost of cos is a great way to solve this problem. In this case, it is very important to install a capacitor bank to recover the charge. By installing a capacitor bank will affect the overall performance of the motor used. The cause of this research is the increasing cost of boarding at the cardboard production unit of PT. Intan Ustrix. As an evaluation, capacitor banks are installed on the H200, AFG, 6PA, FM, and 6PS buses so that low cos costs can be increased. The final result of this charge shows that increasing the cos cost at full load of 325 KW from 0.716 to 0.872 can reduce the actual power cost (S) from 396 KVA to 329 KVA, which can maintain 65 KVA and today's decrease (I) from 498 A to 410 A, the lower the current consumption price of the motor used can increase the resistance of the device to the carton production unit.

The microelectronics industry is heavily tasked with minimizing contaminates at all steps of the manufacturing process. Particles are generated by physical and/or chemical fragmentation from a mothersource. The tools and macrovolumes of chemicals used for processing, the environment surrounding the process, and the circuits themselves are all potential particle sources. A first step in eliminating these contaminants is to identify their source. Elemental analysis of the particles often proves useful toward this goal, and energy dispersive spectroscopy (EDS) is a commonly used technique. However, the large variety of source materials and process induced changes in the particles often make it difficult to discern if the particles are from a common source.Ordination is commonly used in ecology to understand community relationships. This technique usespair-wise measures of similarity. Separation of the data set is based on discrimination functions. Theend product is a spatial representation of the data with the distance between points equaling the degree of dissimilarity.

SummaryThe introduction of low molecular weight heparins has added a new dimension to the pharmacological management of thrombotic disorders. Because of different chemical and pharmacological characteristics, due to the manufacturing process, each LMWH should be considered as a distinct entitity and only be used for its given indication. A list of commercially available LMWHs is included. The mechanism of action of the LMWHs and their use in various disorders are discussed. Available laboratory tests for monitoring LMWHs are presented and their limitations pointed out.

This research aims to formulate marketing strategy to increase visitors of Gembira Loka Garden and Zoo (KRKB Gembira Loka) in Yogyakarta. This research is qualitative research and uses interview, observation, and documentation as data collection method. The data is analyzed by using SWOT analysis with internal and external variable identification. The internal variable shows that location is the main strength of Gembira Loka KRKB with 0.17 by value and 5 by rating. From external variable, the result of EFAS table shows that Gembira Loka KRKB has good enough chance while the thread has less result than the chance. Gembira Loka KRKB is in quadrant 1, which is the position in which a company is considered to be in a beneficial situation due to its chance and strength. In such case, the company can utilize the chance by maximizing the strength. The following strategy to go through in this condition is supporting aggressive planning.

PT. Duta Nichirindo Pratama is a company engaged in the field of Autoparts Manufacture. Barcode is the identity of an item / product on the package. Barcode technology has been used as the identity of goods in a production. Barcodes are used to facilitate the identification of goods produced. Paste the barcode on the packaging of packaging results at PT. Duta Nichirindo Pratama is done manually, but there are often errors attached to the barcode on a similar packaging. This research will design and create a system based on Visual Basic.Net and Arduino to select barcode attachment errors that have the potential to be sent to consumers. The system is designed using Unified Modeling Language (UML) diagrams, database design and interface menu design. The system created will then be tested to detect the black box test. With a computing-based design system that functions to detect barcodes on the packaging automatically, the problem of sticking barcodes on the packaging can be detected.

In an effort to improve electricity services to customers, there needs to be a balance between the supply of electricity and revenue. Payment methods made by the Perusahaan Listrik Negara (PLN) use Postpaid and Prepaid methods. Because services with postpaid methods better meet customer satisfaction, this method is chosen. Sales Accounting Information System is an information technology-based accounting application to support financial transactions in a company to run faster, more precisely and accurately at a reasonable cost. In its operation, it takes competent human resources to not be a source of problems (human error) and adequate infrastructure. To overcome the obstacles that will arise, whether triggered by the application or by the human resources themselves, it is necessary to control both aspects. Based on this research it shows that the application  of  Sales Accounting Information Systems and existing human resources is sufficiently supportive  and  reliable  in  supporting the creation of good control as it is proven that the level of acceptance of sales targets is realized effectively and efficiently.
