<![CDATA[Asean Pharmacies often have difficulty in predicting future product inventory based on previously recorded data. Forecasting is very influential on the decision of the pharmacy owner to determine the number of pharmaceutical products that must be provided by the pharmacy. These problems can be solved by the Forecasting technique using the weighted moving average method to predict how many stocks of goods must be purchased for the next period. Calculation of forecasting for future periods is based on previous quarterly data calculations and can also be done based on the selection of desired periods. The purpose of this research is to build a system in predicting future sales value to increase revenue. The system will be built with the Php programming language and use the Unified Modeling Language to design the system workflow]]>

<![CDATA[We can easily find coffee sellers today, both online and offline. Buying coffee in the form of beans will provide several benefits, such as a more durable aroma and usually of a higher quality. But unfortunately, now there are still many coffee buyers who don't know how to choose coffee beans with good quality. Therefore we need a system that can produce recommendations for selecting the best coffee beans based on determined criteria. This study uses the Decision Support System concept using the SMART method. The SMART method is a decision-making method to solve the problem of multi-objective choice among several criteria, so that later it can produce an effective and efficient analysis. Input criteria that become priority in the recommendation for selecting the best coffee beans are live insects (none requirements), foul smelling beans (non-existent requirements), moisture content, non-coffee dung content, defect values, and flavor (aroma). Of the 10 alternatives tested on this system, there were 5 types of coffee with a “Highly Recommended” rating, 2 types of coffee with a “Recommended” rating, and 3 types of coffee with a “Considered” rating]]>

<![CDATA[Thermo Electric generator element is a conversion system that converts heat into electricity by utilizing heat energy. This tool is designed which comes from wood fuel as a heat source, which can be converted by a Thermo Electric Generator (TEG) into electricity, because not all rural areas have electricity, so researchers use it as a back up for cellphone chargers. This research is a small scale only used for cellphone chargers, the results show that the temperature difference is a very influential factor in producing voltage output and electric current, the greater the temperature gradient (ΔT) produced, the greater the voltage output on the thermo electric. The working principle of the TEG element is that there is a temperature difference on each side, so the TEG will generate electricity. The TEG output is stabilized by an LM317 regulator to a constant 5V DC, the voltage does not fluctuate and does not cause damage to the cellphone. This element is packaged in the form of thin strips with two-sided cross sections, with one side absorbing heat and one side absorbing cold. The tool is designed to consist of 4 TEG with type TEG 12706 arranged in series to increase tension. The results of the research on the hot temperature side of at least 40.1 0C with a voltage of 0.70V DC and a maximum heat temperature of 187 0C with a voltage of 8.55V DC and on the cold side of a minimum of 0 0C a maximum of 26 0C with (P) power 0.105 W, (V) 8V DC voltage and (I) 0.013 mA current.]]>

<![CDATA[Utilization of cloud computing technology in the development of a website has significant developments such as the use of disk storage, memory, and CPUs running in the cloud at a low cost when compared to physical servers. When creates a website, human interaction in carrying out the deployment process such as creating a database and installing the packages needed by the website, all of this is done manually so it takes a lot of time. An automation process is needed to solve this problem by using ansible and shell scripts in the website deployment process. This final project will compare ansible and shell scripts as configuration management for drupal deployments to the Amazon web service EC2 server by analyzing the deployment process time, CPU and memory usage on the server, throughput, and packet loss. Based on tests that shell scripts have performed outperformed ansible at deployment time with a difference of 3 minutes, troughput generated in ansible testing is better with an average of 60,164 Kb/s and 22,009 Kb/s for shell scripts, and ansible usage against the CPU is much better because it does not make the server overloaded.]]>

<![CDATA[The facility layout design greatly affects the performance of a company. Poor facility layout will lead to poor material flow patterns and relatively high movement of materials, products, information, equipment and labor which causes delays in product completion and increases production costs. Facility layout design aims to analyze improvements in production activities. In preparing the layout of the facility, this research applies the 5S method to see what needs to be improved and to redesign the factory layout. The object of this research was conducted at PT. XYZ. The results showed that the redesign of the facility layout of the light bulb processing factory of PT.XYZ consists of several parts that must be improved in order to obtain the best final layout. The redesign of this facility layout does not have to require additional areas, this can be done by rearranging it. Based on the trial questionnaire before applyingthe 5S method,it was found that seiri,seiso,seiton,seiketsu,shitsuke needed improvement, while after redesigning using 5S method, it was found that only seiketsu and shitsuke needed improvement.]]>

<![CDATA[Technological developments with the number and growth of motorized vehicles and the consumption of fuel oil in Indonesia have caused problems for the environment and fuel supply. This problem is even more complicated because the subsidy for its procurement is already very burdensome to the State Revenue and Expenditure Budget. Therefore, comprehensive efforts must continue to be made to find the best solution. This paper discusses the results of research aimed at reducing emissions and reducing motorcycle fuel consumption, by converting the use of gasoline to LPG which is commonly used for cooking. Tests were carried out in the laboratory using a chassis dynamometer to compare torque, power, fuel consumption levels and operating costs, on a carburetor motorcycle engine using gasoline and LPG, either without changing the ignition conditions or by changing the ignition conditions. From this study it was found that LPG fuel has good performance and can be used directly without changing the ignition conditions. However, the performance will be better if the ignition conditions are adjusted. The best level of LPG consumption is 86 km/kg or Rp.58/km, while gasoline is 66 km/l or Rp.98/km.]]>
