Abstract—Electricity is vital for modern society’s welfare. Daily electricity usage depended on the customers’ type. Hence, there was a difference between the connected power with consumption. Therefore, there needed an estimation method for long-term connected power and energy consumption to improve the safety of energy management and operation plan for the generator. This research used the Artificial Neural Network method with a backpropagation algorithm model to estimate the connected power and electricity consumption. This method has the advantage of following past patterns after the training process. This research used data such as total population, Gross Regional Domestic Product, total customers, produced energy, remaining energy, distribution loss, total transformer, peak load, and load factor as the independent data. The energy consumption and connected power served as the dependent data. The data was taken from Srengat Network Service Unit, East Java, for ten years, which started in 2008. This research used literature study, information and data collection, information and data process, data estimation and analysis, and conclusion as the procedures. Based on the results, the best network structure was 9-9-2 with the 10-6 goal, 0.9 momentum value, and 0.15 learning rate to produce the smallest Mean Squared Error of 0.00442 in 2015, Mean Absolute Percentage Error of 7.88% for the connected power, and 11.27% on electricity consumption target.

The globalization era brings rapid development in technology.The human need for speed and easiness pushed them toinnovate, such as in the security field. Initially, the securitysystem was conducted manually and impractical compared tonowadays system. A security technology that is developed wasbiometric application, particularly fingerprint. Fingerprintbasedsecurity became a reliable enough system because of itsaccuracy level, safe, secure, and comfortable to be used ashousing security system identification. This research aimed todevelop a security system based on fingerprint biometric takenfrom previous researches by optimizing and upgrading theprevious weaknesses. This security system could be a solutionto a robbery that used Arduino UNO Atmega328P CH340 R3Board Micro USB port. The inputs were fingerprint sensor, 4x5keypad, and magnetic sensor, whereas the outputs were 12 Vsolenoid, 16x2 LCD, GSM SIM800L module, LED, andbuzzer. The advantage of this security system was its ability togive a danger sign in the form of noise when the systemdetected the wrong fingerprint or when it detects a forcedopening. The system would call the homeowner then. Otherthan that, this system notified the homeowner of all of theactivities through SMS so that it can be used as a long-distanceobservation. This system was completed with a push button toopen the door from the inside. The maximum fingerprints thatcould be stored were four users and one admin. The admin’sjob was to add/delete fingerprints, replace the home owner’sphone number, and change the system’s PIN. The resultsshowed that the fingerprint sensor read the prints in a relativelyfast time of 1.136 seconds. The average duration that wasneeded to send an SMS was 69 seconds while through call was3.2 seconds.
全球化时代带来了科技的飞速发展。人类对速度和易用性的需求促使他们进行创新，比如在安全领域。与今天的安全系统相比，最初的安全系统是手工进行的，不切实际。生物识别技术，特别是指纹识别技术是一种安全技术。指纹识别系统以其准确、安全、可靠、舒适的特点成为一种足够可靠的住房安全识别系统。本课题旨在借鉴前人的研究成果，通过对前人的弱点进行优化和升级，开发一种基于指纹生物识别的安全系统。该安全系统可以解决使用Arduino UNO Atmega328P CH340 R3Board Micro USB端口的抢劫问题。输入是指纹传感器、4x5键盘和磁传感器，输出是12 v螺线管、16x2 LCD、GSM SIM800L模块、LED和蜂鸣器。这种安全系统的优点是，当系统检测到错误的指纹或检测到强行打开时，它能够以噪音的形式发出危险信号。系统会给房主打电话。除此之外，这个系统通过短信通知房主所有的活动，这样就可以用作远距离观察。这个系统是由一个从里面打开门的按钮完成的。最多可以存储4个用户和1个管理员的指纹。管理员的工作是添加/删除指纹，替换房主的电话号码，并更改系统的PIN。结果表明，指纹传感器读取指纹的时间相对较快，为1.136秒。发送短信所需的平均时间为69秒，而通话所需的平均时间为3.2秒。

The use of renewable energy as a source of electrical energyincreases every year. Unfortunately, Indonesia does not have manypower plants that utilize renewable energy sources. The mostpotential renewable energy in Indonesia is the sunlight with the helpof solar panels that converts solar energy into electrical energy.However, the environment could affect the solar panel module andin turn, affect the performance of solar panels or the generatedelectric energy. This research calculated the performance of solarpanels with a single-diode model using the Five Parameters methodthat required solar panel module specification data, the totalradiation absorbed by the solar panel module, and the temperatureof the environment. The Five Parameters method is a methodmodeled after solar panel module performance in the form of thesingle-diode equivalent circuit. The Five Parameters method isreliable in predicting the energy produced by the solar panels whenthe input data is limited. The results for using the Five Parametersin monocrystalline solar panels were Isc = 1.827 A, Imp = 0.662 A,Voc = 18.221 V, Vmp = 15.019 V, Pmp = 9.955 W. And the results inpolycrystalline solar panels were Isc = 1.926 A, Imp = 0.686 A, Voc =17.594 V, Vmp = 14.166 V, Pmp = 9.722 W. Based on the results; itwas concluded that the most efficient and optimised types of solarpanels on natural conditions in Sendang Biru Beach was themonocrystalline solar panel because it produced electrical outputpower of 9.955 W. Therefore, there could be a manufacturer ofsolar energy power plants to reduce the cost of electricity in thecoastal area, such as in Sendang Biru Beach.

Dye-Sensitized Solar Cell (DSSC) is a photoelectrochemical solarcell that uses electrolytes as the cargo transport medium. Gratzeldeveloped it as an alternative resource through the discovery of thelatest solar cell material by mimicking the photosynthesis processcalled photo-electrochemical reactions. According to the researchof Saputra, flavonoids can be used as dyes in Dye-Sensitized SolarCells, while Yanti in 2014 studied the agarwood leaf extract thatcontained flavonoids and chlorophyll. This study aimed to design,build, and test Dye-Sensitized Solar Cell by testing the lightabsorption, and the Performance of Dye-Sensitized Solar Cell usingAgarwood Chlorophyll. This research extracted the Gyrinopsversteegii that was grouped into young, medium and old leaves.With the same dose of extract, 15 grams of agarwood leaves weredissolved in 96% ethanol for 100 ml. The results showed that eventhough the maximum absorption power was the same, or 4.00, themedium leaves absorbed the light more than its wavelength range.The DSSC performance test results obtained the voltages of theyoung, medium, and old agarwood leaves that were 0.398 V, 0.399V, and 0.369 V. The currents of those leaves were 0.01 mA, 0.01mA, and 0.01 mA respectively.

The electrical energy is an energy that is needed by the people. Theelectrical energy, to date, came from several power plants, such aselectric steam power plants and diesel power plants. The communitymust pay the service provider, such as the State ElectricityCompany (PLN) with a rising cost, to obtain electrical energy.However, there were other alternative energies, for example, solarpower plants and windmill power plants. The hybrid system is acombination of two or more different energy sources to meet thedemand. The hybrid system was also expected to solve the problemthat might arise in utilizing other energies, the site condition, andthe unpredicted situation on the power plant. The solution to theseproblems was a hybrid using a monitoring device with ACS 712sensor current parameter, ZMPT101B voltage sensor, LDR solarsensor, hybrid electrical energy power, controller for four electricalsource inputs and three electrical sources for the output load. Thedevice used Arduino Mega 2560 for data processing, ESP 8266 asthe module to connect the device to the internet network and relayas the control actuator. Monitoring and controlling the device usedthe internet network and the implementation of the Internet ofThings (IoT) on the hybrid system plants (PLN, generator, solarpower plant, windmill power plant) that was integrated into thewebsite. The overall test resulted in the comparison average errorvalue between the device and the measuring instrument of thecurrent, voltage, and power. The test also resulted in the averageerror value of the response time for the four input contacts and threeoutput contacts. The average error value of the current was 2.13%,the average error value of the voltage was 0.7%, and the averageerror value from the power parameter was 0%. Meanwhile, theaverage error value of response time was 0.23 seconds. Based onthe above results, it can be concluded that the monitoring andcontrolling system from the website with the implementation of theIoT in the hybrid power system was worked following the design.
电能是人们所需要的一种能源。到目前为止，电能来自几个发电厂，如电力蒸汽发电厂和柴油发电厂。社区必须支付服务提供商，如国家电力公司(PLN)，以不断上升的成本获得电能。然而，也有其他替代能源，例如太阳能发电厂和风车发电厂。混合系统是两种或两种以上不同能源的组合，以满足需求。该混合动力系统还有望解决其他能源利用可能出现的问题，现场条件，以及电厂的不可预测的情况。这些问题的解决方案是使用一个混合监测装置，该装置具有ACS 712传感器电流参数，ZMPT101B电压传感器，LDR太阳能传感器，混合电能电源，四个电源输入控制器和三个电源输出负载。该设备采用Arduino Mega 2560进行数据处理，ESP 8266作为模块将设备连接到互联网并中继控制执行器。监测和控制设备使用互联网网络和物联网(IoT)对混合系统工厂(PLN，发电机，太阳能发电厂，风车发电厂)的实施，集成到网站中。整体测试结果为该装置与测量仪器的电流、电压和功率的比较平均误差值。测试还得出了四个输入触点和三个输出触点的响应时间的平均误差值。电流平均误差值为2.13%，电压平均误差值为0.7%，功率参数平均误差值为0%。同时，响应时间的平均误差值为0.23秒。基于以上结果，可以得出结论，在混合动力系统中实施物联网的网站监控系统是按照设计工作的。

This research aimed to find: (1) the distribution substations configuration in Kesamben Feeder, Wlingi District, (2) how much was the loading in those distribution substations, (3) how much load imbalance in the distribution substation’s load, and (4) how much was the power loss towards the imbalance load. This research used descriptive analysis by analyzing the loading imbalance towards the power loss of distribution substation in one feeder. The results showed that the higher percentage of loading imbalance meant higher power loss. However, although an imbalance percentage was more significant than a smaller percentage, the power loss that occurred might be more substantial due to the probable higher loading percentage so that the power loss in the substation was also influenced by the loading value, apart from the load imbalance.

However, although an imbalance percentage was more significant than a smaller percentage, the power loss that occurred might be more substantial due to the probable higher loading percentage so that the power loss in the substation was also influenced by the loading value, apart from the load imbalance.","PeriodicalId":285860,"journal":{"name":"Frontier Energy System and Power Engineering","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129271707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electricity need in the G4 Building at the State University ofMalang was more than 85 kVA. All electrical devices could beactivated; but when the energy source was inactive, all electricityrequirements were transferred to the diesel power plant (DPP).However, the electrical capacity of DPP was only 20 kVA;therefore, it was necessary to optimize the electrical power load sothat the DPP energy could be absorbed optimally using the roomscheduling and electrical devices priority systems. The DynamicProgramming Algorithm was embedded in the power optimizationsystem to help optimize the work. The power optimization prototypewas used to simulate the 1st floor of the G4 Building’s condition.The system consisted of a controller, a central controller, and auser interface. the controller comprised of a current sensor,microcontroller, and a relay. The central controller consisted ofRaspberry Pi 3 hardware that was installed as the server to answerthe HTTP request from the controller and user interface. The userinterface was displayed in a dynamic web to ease the user inmanaging the electrical devices and entering the room usageschedule. The power optimization system managed the electricalenergy from DPP by turning on the electrical devices according tothe priority value. The power optimization system tests were dividedinto six problems, of which each stage had an error value of 0%.
