Disasters are a series of events that threaten, disrupt people's lives and livelihoods which are caused by natural, non-natural and human factors, resulting in casualties, environmental damage, losses and psychological impacts. Natural disasters have prompted Twitter social media users to upload information about the conditions of areas affected by natural disasters in pictures or only text of the disaster site. At that time, the researcher proposed to analyze the behavior of Twitter social media users towards education levels in Indonesia and the United States. This research provides an overview of the facts about the content shared on Twitter social media, and provides a solution for the extraction of geospatial content on Twitter social media. From the processing of data from Twitter social media, it can be seen that there is no difference in the relationship between Twitter social media users and education levels in Indonesia and the United States and more geospatial information content in the United States than in Indonesia.
灾害是由自然、非自然和人为因素造成的一系列威胁、扰乱人们生活和生计的事件,造成人员伤亡、环境破坏、损失和心理影响。自然灾害促使推特社交媒体用户上传有关受自然灾害影响地区情况的图片或灾难现场的文字信息。当时,研究者提出分析印尼和美国的Twitter社交媒体用户对教育水平的行为。本研究概述了Twitter社交媒体上共享内容的事实,并为Twitter社交媒体上地理空间内容的提取提供了解决方案。通过对Twitter社交媒体数据的处理可以看出,印尼和美国的Twitter社交媒体用户与受教育程度的关系没有差异,美国的地理空间信息内容多于印尼。

COVID-19 was designated as a global pandemic by WHO and Government Regulation of the Republic of Indonesia Number 21 of 2020 concerning Large-Scale Social Restrictions for the handling of Corona Virus Disease 2019 (COVID-19). Eating healthy foods with balanced nutrition can increase the body's immunity during a COVID-19 pandemic. Since many foods that sold freely are not guaranteed in nutritional ingredients, cooking becomes a better alternative. system is a mobile application that provides a recommendation of healthy food recipe by using the Simple Additive Weighting (SAW) algorithm, which has been studied in the previous research of recipe recommendation and gives significant result. Previous research has not examined the appropriate variables and the data are still general food. We conducted a user study to measure the usability of the proposed system. The result of usability testing shows that there is a significant increase in SUS score from 63.5 to 87.
世卫组织和印度尼西亚共和国关于处理2019冠状病毒病(COVID-19)的大规模社会限制的2020年第21号政府条例将COVID-19确定为全球大流行。在COVID-19大流行期间,吃营养均衡的健康食物可以提高身体的免疫力。由于许多免费出售的食品的营养成分不能得到保证,因此烹饪成为更好的选择。系统是一款使用简单加性加权(Simple Additive Weighting, SAW)算法进行健康食品食谱推荐的移动应用程序,该算法在之前的食谱推荐研究中已经得到了研究,并取得了显著的成果。以前的研究没有检查适当的变量,数据仍然是一般的食物。我们进行了一项用户研究,以衡量拟议系统的可用性。可用性测试的结果表明,SUS得分从63.5显著增加到87。

Augmented Reality (AR) technology is one of the educational applications that may be created. AR is a learning tool that may be used to integrate virtual things or objects into a natural environment to engage in real-time. English is a foreign language that must be learnt. For language assistance, pupils must acquire a sufficient command of vocabulary via reading and listening exercises. Two factors contribute to the ineffectiveness of oral communication: pupils who do not have enough vocabulary knowledge and students who do not know how to employ vocabulary non their spoken language. One of the learning media that has been developed is the AR-based English vocabulary learning application which was developed in early April 2020 to September 2020. This application aims to help elementary school students (6-12 years) in learning English vocabulary. Where in the current learning which is due to the pandemic thus making distance learning. The purpose of this study is to measure the usability of the application whose vocabulary has been developed from three aspects, namely effectiveness, efficiency and user satisfaction (ISO 9241). The results of the research conducted show that the usability level of this application is 89% effectiveness, 94% efficiency and 91% user satisfaction. So that this learning application can be said to have good usability and can be used as a supporting medium for learning English vocabulary for children aged 6-12 years independently.
增强现实(AR)技术是可以创建的教育应用程序之一。AR是一种学习工具,可用于将虚拟事物或对象集成到自然环境中以实时参与。英语是一门必须学习的外语。对于语言援助,学生必须通过阅读和听力练习获得足够的词汇掌握。造成口语交际无效的因素有两个:学生没有足够的词汇知识,学生不知道如何使用非口语词汇。已经开发的学习媒体之一是基于AR的英语词汇学习应用程序,该应用程序于2020年4月初至2020年9月开发。此应用程序旨在帮助小学生(6-12岁)学习英语词汇。在当前的学习中,由于疫情,远程学习应运而生。本研究的目的是从三个方面来衡量应用程序的可用性,即有效性、效率和用户满意度(ISO 9241)。研究结果表明,该应用程序的可用性水平为89%的有效性、94%的效率和91%的用户满意度。因此,该学习应用程序可以说具有良好的可用性,可以作为6-12岁儿童独立学习英语词汇的支持介质。

PT XYZ is a finance company that engages in lending. Its activities include branch offices, aiming to increase new customer acquisition. Prospective customer data is required to determine their potential and the location of the nearest branch office. PT. XYZ previously used a third party, but the result was not equal to what was required, and the company was forced to pay to obtain data equal to what was required. Google Maps is a data source that is utilized and freely accessible.This study scraped prospective customer data using robotic process automation. Robotic process automation was developed using UiPath with Google Maps and Plus Codes as data sources. The Haversine method is used to determine the location of the nearest branch office. 595 prospective customer records were obtained through robotic process automation using seven search keywords. The result for 579 prospective customers is correct, but the result for 16 is incorrect. Haversine Method applies to 582 prospective customer records; however, the remaining records lack latitude and longitude, making Haversine Method inapplicable.

Sentiment analysis is a technique of extracting the text data to analyze the opinions and evaluate to obtain the information. Sentiment analysis is performed by internet users on social media or online applications or websites to provide assessments or personal opinions. Tourism in North Sulawesi has grown by 600% in the past four years, and the rise of tourism has sent tourists flocking to the city of Manado. These travelers need a hotel that satisfies their desires, so they need to read about the hotel in the reviews on the hotel reservation service website. This takes a lot of time. To overcome existing problems, sentiment analysis applications were developed to make it easier for potential hotel users to find previous user responses. Additionally, data mining classification techniques are used to help hotel managers determine the satisfaction of previous hotel users using a Naive Bayes algorithm. The five tests performed gave the best result, 76.20% accuracy, with an average of 70.55%. While the average precision is 70.57% and 99.85% for the recall.

The drought that hit Indonesia caused 8 provinces in Indonesia to experience a crisis of clean water and drinking water. Meanwhile, the rainy season in Indonesia occurs for 6 months, starting from November to April. The peak of the rainy season in Indonesia occurs in January, with an average maximum rain intensity of around >700 mm. Based on the situation from the massive potential of rainwater in Indonesia, the possibility to produce clean water and drinking water to overcome drought problems in the dry season. The resulting drinking water must qualify according to its standards. Therefore, the water quality produced from this prototype must be observed. The purpose of this study is to determine the reliability of the filter on the rainwater harvester. The water filter materials used are zeolite natural stone, activated carbon stone, and filter cotton, and further filters are carried out through the Ultrafiltration membrane and electrolysis process. Then the water can be monitored for quality through the user's device. The external water quality of the rainwater harvester is tested with acidity or pH, Total Dissolve Solid or dissolved solids, and Turbidity or water clarity. The change in water quality is seen in TDS, from 50 ppm to 203 ppm. In addition, water quality is seen from the pH of 6.1 to 6.9 and for Turbidity of rainwater which is 0 NTU. Rainwater harvesters can convert rainwater into drinking water. However, in the future, there must be further research on the quality of water produced from rainwater harvesters.
袭击印尼的干旱导致印尼8个省出现清洁水和饮用水危机。同时,印度尼西亚的雨季从11月到4月,为期6个月。印尼雨季的高峰期出现在1月,平均最大雨强约>700毫米。根据印尼雨水潜力巨大的情况,有可能在旱季生产清洁水和饮用水来解决干旱问题。由此产生的饮用水必须符合其标准。因此,必须观察这个原型产生的水质。本研究的目的是确定雨水收集机上过滤器的可靠性。所使用的滤水材料为沸石天然石、活性炭石和过滤棉,并通过超滤膜和电解工艺进行进一步的过滤。然后可以通过用户的设备来监测水的质量。雨水收集器的外部水质通过酸度或pH、总溶解固体或溶解固体以及浊度或水的透明度进行测试。TDS中显示了水质的变化,从50 ppm到203 ppm。此外,水质的pH值为6.1至6.9,雨水浊度为0NTU。雨水采集器可以将雨水转化为饮用水。然而,在未来,必须对雨水采集器产生的水的质量进行进一步的研究。

Reading data from sensors in the context of the Internet of Things (IoT) is one of the main parameters of a high-reliability system. Data reading by sensors is prone to errors due to various variables that the problem cannot accommodate. One method to overcome this problem is the time redundancy algorithm, where the sensor takes data and its best value several times. In this study, the sensors used to calculate the water levels are ultrasonic sensors and resistance. At the river monitoring point, data is sent using the UDP (User Datagram Protocol) protocol that previous studies have used. This research has been done as a prototype with a maximum distance between sensor nodes of one meter. The results of sending data using UDP were successful, with an average delay of 3293 microseconds. And the ultrasonic sensor that has been tested based on transient fault against time redundancy has an accuracy of 94.5% based on a sampling delay of 1000ms.

Pub Date : 2022-12-20 DOI: 10.47111/jointecoms.v2i4.8877
In the Big Indonesian Dictionary (KBBI), boarding house is staying at someone else's house with or without food (by paying monthly). The emergence of new technologies in the industrial revolution will fundamentally change the way people work and live. In the industrial era 4.0, internet technology facilitates communication between humans and humans with machines that are no longer limited by space and time. One technology that is a key aspect of competitiveness in the industrial era 4.0, namely financial technology (fintech), especially in the online payment gateway sector (payment gateway) which, if applied to the boarding house business, will be very helpful in making the rental payment process more efficient and practical. compared to conventional payments. The research methodology used in implementing the Midtrans API (Application Programming Interface) as a Payment Gateway in this website-based boarding house is the waterfall method. In this methodology, several steps are taken to build software, namely: Analysis, Design, Coding, Testing and Maintenance. Testing this website using Blackbox testing. As a result of implementing a payment gateway using the Midtrans API, now boarding house payments can be made online via bank transfer or e-wallet in real time without the need to confirm payments manually again.
在《大印尼语词典》(KBBI)中,寄宿是指住在别人家里,有吃的也有吃的(按月支付)。工业革命中新技术的出现将从根本上改变人们的工作和生活方式。在工业4.0时代,互联网技术使人与机器之间的交流不再受空间和时间的限制。其中一项技术是工业4.0时代竞争力的关键方面,即金融技术(fintech),特别是在在线支付网关领域(payment gateway),如果应用于寄宿业务,将非常有助于使租金支付过程更加高效和实用。与传统支付方式相比。在这个基于网站的寄宿公寓中实现Midtrans API(应用程序编程接口)作为支付网关时使用的研究方法是瀑布方法。在这种方法中,构建软件需要采取几个步骤,即:分析、设计、编码、测试和维护。使用黑盒测试测试本网站。由于使用Midtrans API实现了支付网关,现在可以通过银行转账或电子钱包实时在线支付住宿费用,而无需再次手动确认付款。
