This reseach to study the effectiveness of business transformation strategy in PT Metra Digital Media and to know the difference increasing of company earnings in DOOH (Digital Out Of Home) product in PT Metra Digital Media, before and after implementation of business transformation strategy. The sample cases in this research are 22 customer companies that have not followed the business transformation process, which is advertised through the directory and control samples, and 22 customer companies that have been following the business transformation process are advertising through DOOH (Digital Out Of Home). Calculation data analysis using SPSS (Statistical Data Analysis) test that Independent-Samples T-Test. The results showed that the effectiveness of the implementation of business transformation strategy applies to product indicator, payment method, service and sales, because the OR (Odd Ratio) value is higher in companies that choose DOOH, while those that are not effectively selected are indicator of the period of exposure and popularity, the difference increasing of company earnings on DOOH (Digital Out Of Home) products at PT Metra Digital Media before and after the implementation of business transformation strategy is evidenced from p = 0,016 (sig <0,05) and hypothesis is accepted.

CLASSIFICATION OF THE QUALITY OF HONEY USING THE SPECTROFOTOMETER AND MACHINE LEARNING SYSTEM BASED ON SINGLE BOARD COMPUTER Sagita Rochman; M Nushron Ali Mukhtar

Publisher : UNIPA PRESS

Honey is a natural sweet substance produced by bees with nectar flower ingredients containing various nutrients such as carbohydrates, proteins, amino acids, vitamins, minerals, plant pigments and aromatic components. Honey consists of water (17%), fructose (38.2%), glucose (31.3%), other disaccharides (5%), melezitose (<0.1%), erlose (0.8%) , other oligasakarida (3.6%), minerals (0.2%), amino acids (0.3%). It also contains anti-microbial substances, which can prevent some disease on human. Because it has a high economic value and contains unique substances, honey is often falsified. Honey can be faked in various ways by mixing natural artificial sweetener components or by giving the sugar (sucrose) into the honey, so it is dangerous if given to infants or people suffering from diabetes mellitus. The design of this research used spectrofotometer methode and pattern recognition algorithm (machine learning) system for classifying honey quality. It is based on honey having a chromophore group responsible for absorbance, electronic transition and color giver. We can also knowing the type of honey by using pattern recognition algorithm support vector machine.In this research is used three types of honey to using a spectrophotometer at a wavelength of 500 nm, the absorbance obtained in randu honey type of 0.523-0.654, coffee honey for 0.735-0.824, and rubber honey by 0.947-1.043.

The automatic home control system is currently one of the interesting discussions to be developed, there are many innovations that can be done to facilitate human work in controlling the tools contained in the house. One of them is the use of android for controlling the tools that are inside the house and MIT Invertor is a software for making android applications with a design designed according to the design of the house. The control of home appliances / electronic devices that are often used nowadays are many that are integrated with mobile / smartphone devices. This study aims to design an automated home control system that can facilitate human activities in the home such as turning on and off lights and other electronics by using Android devices as a controller and using the HC-05 bluetooth module as a communication tool. The results of this study can show that the Android application can replace the function of the switch for controlling home appliances.

PT. Indospring, Tbk as a motor vehicle producer industry is demanded to continuously improve the quality of products made in order to remain competitive in the current era of globalization. This is in line with the amount of demand that shows an upward trend. However, the performance of one of the production equipment that is not running optimally causes the output of production is low. From this problem, how is the OEE measurement as the basis of the proposed improvement design to improve the performance of the production equipment so as to achieve World Class Value standard.In performing these performance improvements, it is used OEE method application, Fishbone Diagram, Pareto Diagram in solving the problems that occur. OEE calculation results show that the equipment in the Eye Forming Process has the lowest OEE value compared to Cutting and Process Punching that is equal to 77.94%. This is due to 2 factors namely Performance Factor (83.83%) and Quality Factor (96.18%). The result of analysis that the biggest factor of Performance (Unplanned Down Time) is the first because the process of set up is 733 minutes (52,47%) and secondly because the problem of mandril jam is 450 minutes (32,21%) and Eye Forming Defect ), The first is Eye forming Deformed 1034 pcs (60.50%) and the second is Eye forming Defect Grip as much as 381 pcs (22.29%). Based on the results of the analysis then made an improvement proposal based on the priority of critical problems that occur to improve the performance of equipment in the process.

Publisher : UNIPA PRESS

Determination of poor families in the poverty database is still less than perfect. There is still no multi criteria decision making (MCDM) technique in the grouping of poor families, making the results of the criteria in grouping poor families still far from expectations. So, this article discusses the use of the multi criteria decision making (MCDM) technique for grouping poor families in the poverty database in the Malang district. Fuzzy logic is one technique of MCDM which is commonly used for affirmation of decisions. In a random sampling of 35 families taken from the Malang District poverty database, the classification that was originally obtained was only obtained by 2 (two) classifications of poor families, namely: very poor families and poor families. But after it was calculated using the Fuzzy Logic method, it was found 3 (three) classifications of poor families, namely very poor families, poor families, and almost poor families. The magnitude of the distribution of the poor family classification is: 17 (seventeen) very poor families which previously were 14 (fourteen), 17 (seventeen) families were categorized as poor families that were previously 21 (twenty one), and 1 (one) family in the category of near-poor families that were not previously found. With these results, it can be concluded that the Fuzzy Logic method can and is able to provide better and more diverse results in determining poor families in the Malang District poverty database.
