In recent years, the need for automatic document summarization has been very high, considering the explosion of text data from many sources. Various approaches have been used to summarize documents. One of them is a method based on swarm intelligence. Swarm intelligence is an artificial intelligence method that adopts colony behavior. It utilizes information exchange mechanisms between agents to get better solutions and random techniques for optimum global exploration of the search space. Swarm Intelligence has become the focus of research by many researchers looking at the advantages of the swarm Intelligence method. This paper aims to provide an overview of research in swarm intelligence approaches to automatic document summarization. There are three methods in swarm intelligence presented which have been proven to have very competitive performance on various optimization problems, including automatic document summarization. These methods include particle swarm optimization, ant colony, and artificial bee colony. The main parts of this review are the introduction, explanation of the swarm intelligence method, and the stages of document summarization. At the end of this paper, several challenges are mentioned for future research, especially for automatic document summarization using swarm intelligence.

Modeling and Power Management of Electric Vehicle Charging System 电动汽车充电系统建模与电源管理
P. K. Ray, Anindya Bharatee, Samarpita Panda, I. N. Satiawan
Electric Vehicles (EVs) are gradually becoming the new normal of the automobile industry. To make Electric Vehicles a mainstream automobile there is a need to make the charging stations more accessible, sustainable, and economic. The aim of this paper is to simulate a charging station consisting of a renewable energy source (Photo Voltaic array) and a microgrid to supply power, and to study the station’s power management schemes so that the microgrid experiences the least stress. The design of the station is such that the power flow occurs in both Grid to Vehicle (G2V) and Vehicle to Grid (V2G) directions. Due to this bidirectional nature of the charging station, not only is the pressure on the grids reduced but also the Electric Vehicle itself can be used to stabilize the grid during unequal production of power and load demand. The power flow in this entire system is decided by the mode of operation which depends on the load demand, microgrid production, and the State of Charge of the Electric Vehicle. The recommended power flow scheme for charging an electric vehicle is validated through MATLAB/Simulink results.
电动汽车(ev)正逐渐成为汽车行业的新常态。要使电动汽车成为主流汽车,就需要使充电站更容易使用、更可持续、更经济。本文的目的是模拟一个由可再生能源(光伏阵列)和微电网组成的充电站供电,并研究充电站的电源管理方案,使微电网承受的压力最小。该站的设计是这样的,即功率流发生在电网到车辆(G2V)和车辆到电网(V2G)方向。由于充电站的这种双向特性,不仅可以减轻电网的压力,而且在电力和负荷需求不均衡的情况下,电动汽车本身也可以用来稳定电网。整个系统的潮流取决于负载需求、微网生产和电动汽车的充电状态的运行模式。通过MATLAB/Simulink测试结果验证了推荐的电动汽车充电潮流方案。

Green Campus Establishment Through Carbon Emission and Energy Efficiency Control 通过碳排放和能效控制建设绿色校园
N. Busaeri, N. Hiron, I.A Dwi Giriantari, W. G. Ariastina, I. B. Swamardika
Campus greening has become an obsession for every University; even though being a green campus is not easy, it takes a long-term strategy to be implemented. This article discusses strategies to reduce carbon production and increase efficiency in the use of electrical energy. The campus control policy uses the standards used in the Climate Action Tracker (CAT) and the World Bank standard. While increasing the efficiency of electricity use by observing the annual electricity use of the building and then dividing it by the building area so that the actual energy efficiency index (EEI) identification value is obtained. The object of research is the University of Siliwangi (UNSIL). Data analysis uses field observation data with a range from 2015 to 2021. We use a regression approach to determine conditions in 2030. The results of the investigation on carbon and electricity emissions are divided into four scenarios. The analysis of the efficiency of the use of electrical energy focuses on two types of areas, namely areas with an HVAC system and areas without an HVAC system. The calculation results are recapitulated into six categories. The conclusion from our analysis, it appears that UNSIL needs a breakthrough and a solid commitment to reduce carbon production on campus, misconvert the use of electric vehicles in the campus environment, reduce car and motorcycle activities. The efficiency of electricity use can apply scenario two or scenario 3, which is to keep the electricity consumption rate per year at a minimum of 10%.
校园绿化已成为每所大学的痴迷;尽管成为绿色校园并不容易,但它需要一个长期的战略来实施。本文讨论了减少碳生产和提高电能使用效率的策略。校园控制政策使用气候行动跟踪(CAT)和世界银行标准中使用的标准。同时通过观察建筑年用电量,再除以建筑面积,从而得到实际的能效指数(EEI)识别值,从而提高用电效率。研究对象是西里万吉大学(UNSIL)。数据分析使用2015 - 2021年的野外观测数据。我们使用回归方法来确定2030年的情况。对碳和电力排放的调查结果分为四种情景。电能利用效率的分析主要集中在两类区域,即有暖通空调系统的区域和没有暖通空调系统的区域。计算结果概括为六类。从我们的分析得出的结论,似乎联塞特派团需要一个突破和坚定的承诺,以减少校园内的碳排放,在校园环境中错误地转换使用电动汽车,减少汽车和摩托车的活动。在用电效率方面,可以采用方案二或方案三,即保持每年的用电量至少在10%。

Improvement efficiency of photovoltaic system using modified perturb and observe 利用改进的摄动提高光伏系统效率并进行观察
R. I. Putri, F. Ronilaya, I. Syamsiana, L. Jasa
The limitation of fossil fuels for electricity generation is a very important problem faced today, so that the use of renewable energy is increasing. The photovoltaic system is an electrical energy generator that converts solar energy into electrical energy. The use of PV is increasing because it is pollution-free, free, and low maintenance. However, PV has low conversion efficiency and an increase in PV efficiency can be achieved if it works at the maximum power point (MPP). So it's needed a maximum power point tracking (MPPT) controller. In this article, a modified P&O (MP&O) MPPT controller is designed for a standalone PV system using a boost converter. MP&O finds the MPP by adjusting the duty cycle of the boost converter based on current and voltage measurements. Based on the simulation results, the MP&O MPPT algorithm has a better performance than P&O. MP&O can follow changes in irradiance and produce greater maximum power and faster tracking time than the P&O algorithm. For some irradiance conditions, MP&O can achieve an average efficiency of 92.65% while P&O is 83.45%.
化石燃料发电的局限性是当今面临的一个非常重要的问题,因此可再生能源的使用正在增加。光伏系统是一种将太阳能转化为电能的电能发生器。光伏的使用越来越多,因为它是无污染的,免费的,低维护。然而,PV的转换效率较低,如果在最大功率点(MPP)工作,则可以实现PV效率的提高。因此需要一个最大功率点跟踪(MPPT)控制器。在本文中,设计了一种改进的P&O (MP&O) MPPT控制器,用于使用升压转换器的独立光伏系统。MP&O通过根据电流和电压测量值调整升压变换器的占空比来确定MPP。仿真结果表明,MP&O算法比P&O算法具有更好的性能。MP&O算法可以跟踪辐照度的变化,比P&O算法产生更大的最大功率和更快的跟踪时间。在一定辐照度条件下,MP&O的平均效率为92.65%,P&O的平均效率为83.45%。

Dielectric Dissipation Factor Measurement of Power Equipment under Distorted Excitation Voltage 电力设备在畸变激励电压下的介电损耗系数测量
Pratic A Muntakim, Jun-yan Zhang, Shubin Zhang, B. Phung
The dielectric dissipation factor (DDF) is a useful parameter for the diagnosis of high voltage equipment insulation condition. Traditionally, the AC power grid voltage was considered pure sinusoidal. Due to the increasing presence of non-linear loads in the power system, the grid voltage nowadays gets distorted with high frequency harmonics. This paper investigates the impact of distorted voltage on the DDF measurement. Based on a circuit model with the polarization loss, a mathematical formula is derived which shows that, given the same RMS applied voltage, the DDF value will decrease with increasing harmonic distortion level. The theoretical formulation is implemented in computer simulation using MATLAB Simulink to validate the results. Laboratory experiments were carried out on a 33kV dry-type current transformer which confirmed the monotonically decreasing pattern, but the trend is more complex.
介质耗散系数(DDF)是诊断高压设备绝缘状态的一个有用参数。传统上,交流电网电压被认为是纯正弦的。由于电力系统中非线性负荷的增加,电网电压受到高频谐波的畸变。本文研究了失真电压对DDF测量的影响。在考虑极化损耗的电路模型的基础上,推导出了当有效值电压相同时,DDF值随谐波失真程度的增加而减小的数学公式。利用MATLAB Simulink对理论公式进行了计算机仿真验证。在33kV干式电流互感器上进行了室内实验,证实了其单调递减规律,但其变化趋势较为复杂。

Clustering of Earthquake and Volcanic Eruption Trauma Survivor Groups using K-Means Algorithm 基于K-Means算法的地震和火山爆发创伤幸存者群体聚类
Sri Widyanti Ginting, R. S. Hartati, M. Sudarma, I. B. Swamardika
Prolonged trauma conditions in a person have the potential to become Post-Traumatic Stress Disorder (PTSD). The American Psychological Association (APA) defines PTSD as an experience of someone who experiences a traumatic event that can cause disturbances in self-integrity, feeling of helplessness and specific trauma. People who are directly affected by earthquakes and volcanic explosions generally experience trauma. In order to reconcile the survivors of trauma, this study will categorize trauma survivors from Mount Sinabung's eruption in Karo Regency and the Ambon City Earthquake according to their level of trauma. The clustering process uses the Data Mining, a method to extract and identify trauma survivor data in order to produce the required information. The algorithm on K-Means is used in the computational process. The algorithm on K-Means has advantages in computational efficiency and ease of use. The data collection instrument in this study used the Impact of Even Scale-Revised (IES-R) Questionnaire which offered a common language and standard criteria for the classification of mental disorders. Information on the trauma survivors cluster of Mild, Moderate, and Severe trauma levels will be generated using the computational and iteration process supported by the Orange application. The results of the research on grouping trauma survivors using the K-means algorithm with the support of an application that helps the iteration process of survivor data processed through the IER-S questionnaire provide information that is useful for healing trauma survivors.
一个人的长期创伤状态有可能成为创伤后应激障碍(PTSD)。美国心理协会(APA)将创伤后应激障碍定义为一种经历创伤性事件的人的经历,这种经历会导致自我完整、无助感和特定创伤的紊乱。直接受到地震和火山爆发影响的人通常会经历创伤。为了调和创伤幸存者,本研究将根据创伤程度对Karo Regency Sinabung火山喷发和Ambon市地震的创伤幸存者进行分类。聚类过程使用数据挖掘,这是一种提取和识别创伤幸存者数据以产生所需信息的方法。在计算过程中采用K-Means算法。基于K-Means的算法具有计算效率高、易于使用等优点。本研究的数据收集工具采用《影响均匀量表修订版》(IES-R)问卷,为精神障碍的分类提供了一种通用的语言和标准标准。关于轻度、中度和重度创伤级别的创伤幸存者集群的信息将使用Orange应用程序支持的计算和迭代过程生成。使用K-means算法对创伤幸存者进行分组的研究结果,在一个应用程序的支持下,该应用程序有助于通过IER-S问卷处理的幸存者数据的迭代过程,为创伤幸存者的治疗提供有用的信息。

Design and Control System of Sluice Gate With Web-Based Information 基于web信息的水闸控制系统设计
I. G. M. N. Desnanjaya, I. M. A. Nugraha
In the rice fields, there is what is called a small stream where water flows to irrigate the rice fields. When it rains it will cause flooding in the rice fields. Floods in rice fields generally occur in rice fields that use a rain-fed water system (depending on the rain). By using a rainfed rice field system, controlling the water entering the rice fields becomes difficult due to the uncertain water level. One of the problems faced by farmers is controlling water flowing into the fields. Seeing these problems, a Door Control system with Web-Based Information was designed and built. This system can display a graph of the meeting water level on the website and can control the meeting door. So that this system helps farmers in getting information on the water level of the meeting and can control the meeting door remotely. The components used to design this system are Arduino Uno as a data processing center, SIM 900 Module for sending data to the database and as SMS recipients, Servo Motor for moving meeting doors, and ultrasonic sensor HCSR04 as water level readings at meetings. Based on the website system test using ISO 1926, a good score was obtained. For the functional system, it gives a good score with a total value of 30. For reliability, it gives a value of 0.99, which indicates that the tool fulfills the reliability. In the usage test, 66.75% gave a good score. on efficiency, it can be concluded that the sluice gate control system with web-based information gets an average score of 87.8 with grade B. Meanwhile, the average load time is 650.8 ms. Based on Nielsen's standards, the average load time of the sluice gate control system with web-based information is good.
在稻田里,有一条小河,水从那里流过来灌溉稻田。下雨时,稻田会淹水。稻田的洪水通常发生在使用雨水灌溉系统的稻田(取决于降雨)。采用雨养水田系统,由于水位的不确定性,使进入稻田的水量控制变得困难。农民面临的问题之一是控制流入田地的水。针对这些问题,设计并构建了一个基于web的门控系统。该系统可以在网站上显示会议水位的图形,并可以控制会议门。因此,该系统可以帮助农民获得会议水位的信息,并可以远程控制会议门。设计该系统的组件是Arduino Uno作为数据处理中心,SIM 900模块作为数据发送到数据库和短信接收,伺服电机用于移动会议门,超声波传感器HCSR04作为会议水位读数。采用iso1926对网站系统进行了测试,取得了良好的成绩。对于功能系统,它给出了一个很好的分数,总分为30分。对于可靠性,它给出了0.99的值,这表明该工具满足可靠性。在使用测试中,66.75%的人给出了好的分数。在效率方面,基于web信息的水闸控制系统平均得分为87.8分,为b级,平均加载时间为650.8 ms。根据尼尔森标准,基于网络信息的水闸控制系统的平均加载时间较好。

When it rains it will cause flooding in the rice fields. Floods in rice fields generally occur in rice fields that use a rain-fed water system (depending on the rain). By using a rainfed rice field system, controlling the water entering the rice fields becomes difficult due to the uncertain water level. One of the problems faced by farmers is controlling water flowing into the fields. Seeing these problems, a Door Control system with Web-Based Information was designed and built. This system can display a graph of the meeting water level on the website and can control the meeting door. So that this system helps farmers in getting information on the water level of the meeting and can control the meeting door remotely. The components used to design this system are Arduino Uno as a data processing center, SIM 900 Module for sending data to the database and as SMS recipients, Servo Motor for moving meeting doors, and ultrasonic sensor HCSR04 as water level readings at meetings. Based on the website system test using ISO 1926, a good score was obtained. For the functional system, it gives a good score with a total value of 30. For reliability, it gives a value of 0.99, which indicates that the tool fulfills the reliability. In the usage test, 66.75% gave a good score. on efficiency, it can be concluded that the sluice gate control system with web-based information gets an average score of 87.8 with grade B.
