<![CDATA[In a company, it's important to think about inventory patterns. Because without inventory management, companies can suffer losses. Perceived losses if the goods owned in the company's stock are lacking but the interest in goods is very high can cause consumers to switch to other companies and will reconsider making transactions. This also happens if the goods available in the warehouse have a large amount but the consumer's interest in the goods will experience a slight loss especially if the item has an active period so there is a buildup or loss. Therefore an item management strategy is needed. One company that can use both of these methods is Starbucks Legian. Because using the Economy Order Quality method can determine the number of subsequent orders and using a priori algorithm can help companies determine the items that need to be held more and can be given as promos with other products sold or given discounts. Using these two methods will attract consumers to shop at Starbucks Legian.]]>

<![CDATA[Pembangkit Listrik Tenaga Surya or called PLTS Microgrid is one solution to meet the needs of electricity. Microgrid is a system designed by utilizing 2 sources of electrical energy, one of the energy sources can be obtained from PV with a PLN grid source. In this system, the management is carried out with different treatments on each load. For lights and fans, the load is regulated by the PIR sensor. both will light up when the sensor detects the presence of humans. Meanwhile, the charger itself can be used at any time. The microgrid system can work with a switching process for 1 second with the condition that when the voltage on the battery is less than 12,1 V, the system will receive a supply from PLN. PV is capable of charging the battery with a voltage in the morning and afternoon of 18V with the output voltage generated by the Buck Boost Converter still not reaching the set point, which is still at 12,5 v until 13 V. This is due to the control on the hardware still not working perfectly. The use of PIR sensors to regulate load ignition can reduce excessive load usage. In this system the current sensor readings are not good when integration testing is carried out, so the load power that is read does not match the power in the plan, which is 8 W while in the planning it is 26 W.]]>

<![CDATA[This study aims to determine the effect of temperature on the characteristics of bio-oil on the pyrolysis of Sunan candlenut oilcake (SCO). SCO is the waste that arises from the compression of the Sunan candlenut seeds in the biodiesel production process, which can be converted into bio-oil as a raw material for bio-fuel. Furthermore, to obtain bio-oil, SCO was pyrolyzed in a fixed bed reactor and the temperature varied at 250,350, 450, 550, and 650 oC to find the best conditions. The bio-oil was tested for the properties of the hydrocarbon compounds contained using gas chromatography-mass spectrometry (GC-MS) and then compared. The results show that the percentage of hydrocarbons increases with increasing temperature. The bio-oil from the pyrolysis of SCO contains more than 70% hydrocarbon compounds at temperatures above 450 oC. Aromatic hydrocarbon increases with increasing temperature and are stable from 550 oC. Based on the results, it can be stated that the pyrolysis of SCO with the aim of obtaining bio-oil with optimum hydrocarbons content can be carried out at temperature intervals of 450 to 550 oC.]]>

<![CDATA[This paper aims to examine the application of Neuro fuzzy membership function analysis to predict the emotions of children who like to play games. The game that has been developed is a type of game based on Balinese local wisdom, which innovates the Balinese culture-based legend I Rajapala. Rajapala who married an angel had a son named Durma. Rajapala and Durma are used as game characters that can be played on behalf of game players. Game-factor and emotional variable data were collected using a questionnaire integrated into the game system, as well as motivational data from points achieved and the use of time recorded in the game system. The data were analyzed by Sugeno Neuro Fuzzy system with hybrid and backpropagation methods. The results obtained are as follows: (1) Emotional Balinese game players can be predicted from game-factors and motivations of game players. This was shown from the FIS output (Eo) of the neuro fuzzy training analysis and the RMSE (Eo=36.8; RMSE=4.6610), the testing analysis was (Eo=33.0; RMSE=4.4528), and the checking analysis was (Eo=37.8; RMSE=4.7479) with a difference of less than 13% (training=2.72%; testing=3.0%, and checking=12.77%). In other words, if it is analyzed descriptively was (M=37.83; SD=5.3573), the output of neuro fuzzy is obtained more than 87.23%. (2) The emotional level of the child was categorized as a positive, the child's motivation was moderate and the response to the game was positive. These findings can be taken into consideration in choosing the type of game to be played in order to increase motivation and control children's emotions. Besides that, innovating games based on local wisdom is expected to preserve local Balinese culture.]]>

<![CDATA[The microgrid system is an interconnected network system of various energy sources distributed into a small network that can operate independently or connected to the main network (PLN). The purpose of using the system microgrid is to create a more efficient method of generating electrical energy by utilizing renewable energy as a source of electrical energy. In this final project, a DC system microgrid with hybrid PV and PLN is made to supply a 12 V 19 W DC pump used in the pond. Two 50Wp PVs are installed in series and one 12V 33Ah lead acid battery is used as storage energy for PV output. Two 50 Wp PVs arranged in series are capable of producing a maximum voltage of up to 34 V when the irradiation value is above 1000 Wb/m2. With the use of PID control, the buck converter is able to reduce the PV output voltage from 34 V to a constant with an average output voltage of 13.798 V. The output of the buck converter is used as the value of the voltage charging on the battery. By doing test charging a battery close loop, the original battery voltage value was 12.48 V to 12.77 V with a charging time of 80 minutes. For the backup source, namely the PLN grid, used uncontrolled fullwave rectifier is as a rectifier from 220Vac to 24 Vdc. Because the required load voltage is 12 V, used voltage regulator is which regulates the output of the uncontrolled fullwave rectifier from 24 Vdc to 12 Vdc. The process switching between the PV source and the PLN grid source is carried out using the battery voltage value parameter. When the battery voltage value is more than 11.96 V the microcontroller will condition the main source relay (PV) to be ON and the backup source relay (PLN grid) is OFF, but when the battery voltage value is less than 11.96 V the microcontroller will condition the relay. the main source (PV) is OFF and the backup source relay (PLN) is ON.]]>
