Prior to traveling, one of the most important things to pay attention to is to determine the travel route, especially the shortest path to be taken. In this study, the method used to determine the shortest route is the conventional method and the Heuristic method. These two methods will be compared to find out methods which can provide the best result. For conventional methods, the authors use the Floyd- Warshall algorithm whereas for the Heuristic method, the greedy algorithm is employed. The Floyd-Warshall algorithm takes into account all possible routes so that there are some routes are displayed while the greedy algorithm checks every node that is passed to select the shortest route (Local Optimum) so that the time needed in searching is faster. Based on the conducted testing, the final result obtained is the Floyd- Warshall algorithm provides a better solution, namely the mileage was 22.7 km and the greedy algorithm covered a mileage of 24.8 km. This result indicated that a longer time is required because it takes the distance to all points into account.
在旅行之前,要注意的最重要的事情之一是确定旅行路线,特别是要走的最短路径。在本研究中,确定最短路线的方法是常规方法和启发式方法。将这两种方法进行比较,找出能够提供最佳结果的方法。对于传统方法,作者采用Floyd- Warshall算法,而对于启发式方法,作者采用贪心算法。Floyd-Warshall算法考虑了所有可能的路由,因此会显示一些路由,而贪心算法会检查经过的每个节点,选择最短的路由(局部最优),从而使搜索所需的时间更快。根据所进行的测试,最终得到的结果是Floyd- Warshall算法提供了更好的解决方案,即里程为22.7 km,贪婪算法覆盖的里程为24.8 km。这个结果表明,由于考虑到所有点的距离,需要更长的时间。

The Golay codes are widely used Error Correction Codes (ECCs) that are used to recognize and correct errors in digital systems. This paper proposes an efficient architecture for hardware implementation of Golay code encoder. The proposed architecture has three important units: 1) data unit, 2) control unit and 3) conversion unit. These units are carefully designed such that the developed architecture can work for a message with ‘0’ and ‘1’ Most Significant (MS) bits. The performance of the developed encoder architecture is verified using FPGA devices. The results demonstrate that the developed encoder architecture provides a promising advantage compared to other encoder architectures for Golay codes.
Golay码是一种广泛使用的纠错码(ecc),用于识别和纠正数字系统中的错误。本文提出了一种高效的Golay码编码器硬件实现体系结构。提出的架构有三个重要单元:1)数据单元,2)控制单元和3)转换单元。这些单元经过精心设计,使得所开发的体系结构可以用于具有“0”和“1”最高有效位(MS)的消息。利用FPGA器件验证了所开发编码器结构的性能。结果表明,与其他编码体系结构相比,所开发的编码器体系结构对Golay码具有很好的优势。

The government efforts to reduce society poverty rate by carrying out various programs in order to fulfill the basic needs of citizens properly and improve the socio-economic welfare of the poor to reach a prosperous Indonesian society. One such program is a social assistance program for poverty society. To reduce the risk of distributing aid that is not on target, it becomes very important for decision makers to determine citizens who are the priority of beneficiaries according to the applicable criteria. There are various Multi-Criteria Decision-Making (MCDM) methods that can be used in decision-making problems that involve many criteria. This paper tries to apply the PROMETHEE method in evaluating the advisability of the citizens' condition to receive government assistance with the weighting criteria based on entropy weight. There are six criteria used, namely, age, sex, education level, main occupation, skills, and marital status. The result showed that the determination of the feasibility of citizens as recipients of government assistance using entropy weight in PROMETHEE method which its output is the priority ranking of the alternative has an accuracy rate is 80.39 percent. The result of this research can be used to help a decision-maker to decide who are eligible for receiving the assistance government.
政府努力通过实施各种方案来降低社会贫困率,以适当地满足公民的基本需求,提高穷人的社会经济福利,从而实现繁荣的印度尼西亚社会。其中一个项目是针对贫困社会的社会援助项目。为了减少发放不到位的援助的风险,决策者根据适用的标准确定哪些公民是优先受益者就变得非常重要。多准则决策(Multi-Criteria Decision-Making, MCDM)方法可用于涉及多准则的决策问题。本文尝试用基于熵权的赋权标准,将PROMETHEE方法应用于评价公民接受政府救助状况的适宜性。使用了6个标准,即年龄、性别、教育程度、主要职业、技能和婚姻状况。结果表明,PROMETHEE方法中熵权法确定公民作为政府救助对象的可行性,其输出为备选方案的优先级排序,准确率为80.39%。本文的研究结果可以帮助决策者决定哪些人有资格获得政府的援助。

GraphQL is a new concept in building an API. GraphQL is a Query Language developed by Facebook and implemented on the server side. Although it is a query language, the GraphQL is not directly connected with the database. In other words, GraphQL is not limited to both SQL and NOSQL databases. GraphQL which uses single endpoints is more efficient than RESTful which uses many endpoints but GraphQL will also be a little slower in querying complex databases and have many relationships beside that REST is built on multiple endpoints for specifying the return data, oftentimes multiple endpoints be required to be called when it needed. It will increase the number of client-server calls for displaying the data to the user and this could possibly result in poorer performance of the service in a Web Application needs. This paper analyses the performance calculation of the GraphQL and RESTful technologies in the web information services system of the Institute for Research and Community Service (LP2M) of the Hasanuddin University. The performance parameters used are Response Time and Throughput. Our results showed that in terms of speed RESTful is still superior to the GraphQL since the speed of RESTful is consistently stable in terms of access time and data size. Whereas the GraphQL is dynamic since it can be change depend on demand fluctuation.
GraphQL是构建API的一个新概念。GraphQL是一种由Facebook开发并在服务器端实现的查询语言。虽然GraphQL是一种查询语言,但它并不直接与数据库连接。换句话说,GraphQL并不局限于SQL和NOSQL数据库。使用单个端点的GraphQL比使用多个端点的RESTful更高效,但是GraphQL在查询复杂数据库时也会慢一些,并且有许多关系,除此之外,REST是建立在多个端点上来指定返回数据的,通常需要在需要时调用多个端点。它将增加用于向用户显示数据的客户机-服务器调用的数量,这可能会导致Web应用程序所需的服务性能下降。本文分析了GraphQL和RESTful技术在Hasanuddin大学研究与社区服务研究所(LP2M)的web信息服务系统中的性能计算。使用的性能参数是响应时间和吞吐量。我们的结果表明,就速度而言,RESTful仍然优于GraphQL,因为RESTful的速度在访问时间和数据大小方面始终稳定。而GraphQL是动态的,因为它可以根据需求波动进行更改。

Business process is a collection of all activities and tasks in achieving the goals of a company or an organization. This study aims to find the gap value obtained from the business process model matching technique. Process model matching can be used to identify similar processes or activities in a business process model. There are three things in finding similarities between each process model, including the similarity of label, structural similarity, and behavioral similarity. Probabilistic Latent Semantic Analysis is used to get the probability of topics. The calculation result of the probability of the document in the topic with the similarity value obtained is 0.063. Dice Coefficient is used to calculate the similarity of the structure of the business process model compared to showing the similarity results with a precision value of 0.695. Jaccard Coefficient is used to calculate the similarity of behavior of a business process model compared to showing the results of similarities with a precision value of 0.342. By looking at the precision value of the three mechanisms for measuring similarities, it can be said that business processes that are running are actually not in accordance with the business processes in the SOP.
业务流程是实现公司或组织目标的所有活动和任务的集合。本研究旨在找出业务流程模型匹配技术所获得的差距值。流程模型匹配可用于识别业务流程模型中的类似流程或活动。寻找每个流程模型之间的相似性有三个方面,包括标签相似性、结构相似性和行为相似性。概率潜在语义分析用于获取主题的概率。得到的相似度值在该主题中出现的文档的概率计算结果为0.063。Dice Coefficient用于计算业务流程模型结构的相似性,以显示精度值为0.695的相似性结果。Jaccard系数用于计算业务流程模型的行为相似度,并以精度值0.342显示相似度的结果。通过查看用于度量相似性的三种机制的精度值,可以说正在运行的业务流程实际上与SOP中的业务流程不一致。

In this digital era, social media is used as a means to perform social activity and advertisements by companies. All of companies from small to big online shop created an endorsement to promote their products, and then it can be recognized. As a fast food restaurant, KFC launched the latest product KFC Salted Egg, As known, KFC often release unique products such as ChoChick, chicken sprinkled with chocolate spice. KFC created an endorsement by selecting Raditya Dika as an endorser. By using endorsement, KFC will get a good or bad sentiment. Analysis is needed to gain the sentiment’s effect of the endorsement. In conducting sentiment analysis, data was collected from two social media comments, YouTube, and Twitter. According to research conducted by Statista in 2007, the most widely used social media in Indonesia was YouTube while twitter was seventh. Even so, the development of twitter users time by time was increasing. It indicated that twitter was widely used. Naive Bayes was chosen to perform sentiment analysis because this method has a high accuracy in various studies. The stages of this research are divided into two periods, before and after endorsement. Data has been collected through the process of prepossessing, and then classification is done by using confusion matrix. The result showed that Naive Bayes has an accuracy rate more than 84%. However, negative sentiment rose by 12.51%. Neutral sentiment in this study contains neighbors of social media users who want to try the product, but the result after neutral sentiment endorsement decreased. It can be concluded that 9.77% of the decline has tried the product.
在这个数字时代,社交媒体被公司用作进行社交活动和广告的手段。所有的公司从小到大的网上商店都创建了一个代言来推广他们的产品,然后才能得到认可。作为一家快餐店,肯德基推出了最新产品肯德基咸蛋,众所周知,肯德基经常发布独特的产品,如ChoChick,鸡肉撒上巧克力香料。肯德基通过选择拉蒂亚·迪卡作为代言人创造了一个代言。通过使用代言,肯德基会得到一个好或坏的情绪。需要进行分析,以获得背书的情绪效果。在进行情绪分析时,收集了YouTube和Twitter两个社交媒体评论的数据。根据Statista在2007年进行的研究,印度尼西亚最广泛使用的社交媒体是YouTube,而twitter排名第七。即便如此,随着时间的推移,twitter用户的发展也在增加。这表明twitter被广泛使用。选择朴素贝叶斯进行情感分析是因为该方法在各种研究中具有较高的准确性。本研究阶段分为背书前和背书后两个阶段。通过先验处理收集数据,然后利用混淆矩阵进行分类。结果表明,朴素贝叶斯的准确率在84%以上。相反,负面情绪上升了12.51%。本研究中的中立情绪包含社交媒体用户的邻居,他们想要尝试产品,但中立情绪背书后的结果有所下降。可以得出的结论是,9.77%的下降已经尝试了该产品。

Black Orchid is a typical plant originating from Borneo Island. Black orchid is protected because its presence in nature that begins to extinct. Therefore, cultivation and multiplication are urgently needed in order to overcome the extinction of black orchid. Yet, the cultivation of black orchids is a difficult thing to do. This is caused by the lack of information or knowledge in cultivating black orchid. This study was conducted by employing Certainty Factor method in expert system design that allowed users to know the conditions that happened in accordance with the selected symptoms of the black orchid. Moreover, the results showed that the expert system used in Certainty Factor method contributed to providing the condition analysis experienced by black orchid in accordance with the symptoms that have been selected. Furthermore, this system was also able to provide solutions to the conditions that occurred. In addition to that, based on the previous results of validity tests, this expert system contributed to yield accuracy results of 100%. Thus, these results indicate the suitability of information generated by the system with information from experts as well as observations of conditions performed on black orchid plants.
黑兰花是一种典型的植物,原产于婆罗洲岛。黑兰花受到保护,因为它在自然界的存在,开始灭绝。因此,为了克服黑兰花的灭绝,迫切需要栽培和繁殖。然而,种植黑兰花是一件困难的事情。这是由于缺乏栽培黑兰花的信息或知识造成的。本研究采用专家系统设计中的确定性因子法,使用户能够根据所选择的黑兰花症状了解所发生的情况。结果表明,确定性因子法所使用的专家系统有助于根据所选择的症状提供黑兰所经历的状态分析。此外,该系统还能够针对发生的情况提供解决方案。此外,在前人效度测试结果的基础上,该专家系统的准确率达到100%。因此,这些结果表明系统生成的信息与专家提供的信息以及对黑兰花植物进行的条件观察的适用性。
