The need and development of information systems continue to occur. The presence of an information system allows communication between users in counselling services. The development of information systems is a complex concept and has challenges in addition to problems. The main problem is that the requirements for the system are often not explained, making it difficult for designers and system analysts to understand, and adapt the design results to the needs of each user. The motivation of this research is to develop a counselling information system with an object-oriented approach. The method used in the development is the implementation of analysis and building a structured model with the output forming classes and their associations. The final result shows that the class that has been formed reduces the complexity of the system.
信息系统的需求和发展不断发生。信息系统的存在使咨询服务的用户之间能够进行交流。信息系统的发展是一个复杂的概念,除了问题之外还面临着挑战。主要的问题是,系统的需求往往没有解释,这使得设计师和系统分析人员很难理解,并使设计结果适应每个用户的需求。这项研究的动机是开发一个面向对象方法的咨询信息系统。开发中使用的方法是实现分析和构建结构化模型,并输出形成类及其关联。最后的结果表明,所形成的类降低了系统的复杂性。

At this time the processing of coconut into coconut flour is widely carried out by factories, especially in areas that have a large population of coconuts. Hal ini disebabkan karena keuntungan yang didapat dari hasil pengolahan kelapa tersebut bisa mendapatkan keuntungan yang besar. This is because the profits obtained from the results of processing coconut can get large profits. The problem that has occurred so far is that there are many people who want to process coconuts, but are not accompanied by sufficient knowledge and knowledge of the quality of coconuts that the factory wants, so it is undeniable that there are also many coconuts that have been processed into coconut flour but are not sold in the market. The analysis method used in this study used an image processing method based on digital images with a GUI (Graphical User Interface) interface media that utilizes matlab software. Image processing consists of several processes, the first of which is the operation of changing the color to grayscale. The second process is a grayscale to binary color change operation using the threshold method. The third process is the morphological process of filling holes to remove noise from the threshold image results. The results of the study using the Image Management method are expected to provide knowledge and knowledge to the public about the quality of coconuts expected by the factory, especially to identify the differences between rotten coconuts and rotten coconuts.
在这个时候,将椰子加工成椰子粉是由工厂广泛进行的,特别是在拥有大量椰子的地区。我是杨根东省长,我是杨根东省长,我是杨根东省长,我是杨根东省长,我是杨根东省长。这是因为从加工椰子的结果中获得的利润可以获得很大的利润。到目前为止出现的问题是,有很多人想加工椰子,但没有足够的知识和知识来陪伴工厂想要的椰子质量,所以不可否认的是,也有很多椰子被加工成椰子粉,但没有在市场上销售。本研究采用的分析方法采用基于数字图像的图像处理方法,采用GUI (Graphical User Interface,图形用户界面)界面介质,利用matlab软件。图像处理由几个过程组成,首先是将颜色变为灰度的操作。第二个过程是利用阈值法进行灰度到二值色的变换操作。第三个过程是形态学过程填充孔洞,去除阈值图像结果中的噪声。利用形象管理方法的研究结果,期望能为公众提供工厂所期望的椰子质量的知识和知识,特别是识别烂椰子和烂椰子的区别。

The need for clean water around the world is related to the increasing population, especially in Teupin Batee Village, Aceh Besar District. In addition to surface water, groundwater is one of the potentials that can be utilized by the community, particularly for household needs. The purpose of this study is to identify the aquifer layer using the geoelectric method. One of the geophysical methods that can be used to map groundwater potential is the geoelectrical method based on the resistivity value of subsurface rocks. This study uses the Wenner-Schlumberger array because it can map subsurface structures both vertically and horizontally. From the results of the study, it was found that there are four different layers in this research area including, the top soil layer, hard rock, tuffaceous sand and sand layer as aquifer layer. The top soil layer is mixed with tuff, sand and volcanic breccia to a depth of 8 m with a resistivity value of 5-25 ?m. The Hard rock layer is at a depth of 8 m – 30 m with a resistivity value of 45-220 ?m. The tuffaceous sand layer has a resistivity value ranging from 25-55 ?m. While the sand layer or aquifer is at a depth of 10 m – 60 m with a resistivity value of <10 ?m which is separated by a layer of tuffaceous sand between the two aquifer layers.
世界各地对清洁水的需求与人口增长有关,特别是在亚齐Besar区的Teupin Batee村。除了地表水之外,地下水是社区可以利用的潜力之一,特别是满足家庭需要。本研究的目的是利用地电方法识别含水层。基于地下岩石电阻率值的地电法是绘制地下水势的地球物理方法之一。这项研究使用Wenner-Schlumberger阵列,因为它可以垂直和水平绘制地下结构。从研究结果来看,研究区有4个不同的层,包括表层土层、硬岩层、凝灰质砂层和作为含水层的砂层。表层为凝灰岩、砂、火山角砾岩混合土层,深度8 m,电阻率5 ~ 25 μ m。硬岩层深度为8 m ~ 30 m,电阻率值为45 ~ 220 μ m。凝灰岩砂层的电阻率值为25 ~ 55 μ m。砂层或含水层在10 ~ 60 m深度,电阻率值<10 μ m,两含水层之间隔一层凝灰质砂层。

Technological development has led to the emergence of cooperation separately both geographically and in time zone in an organization in the form of a virtual organization. PT XYZ's Microsoft Solution and Service (DMSS) Department is one of the departments that provides digital services in the form of One-Stop-Solutions on Digital Services, both in on-premise and cloud infrastructure models with products and solutions based on Microsoft products for customers. In his service during the Covid-19 pandemic, this department implements virtual team coordination so that product development can continue as planned. However, on the other hand, the effectiveness of performance in implementing virtual organizations is still a challenge for the company. This is the focus of research to find out what factors influence the effectiveness of cooperation in the application of virtual organizations at PT XYZ in general and specifically in the Microsoft Solution and Service Department. This study conducted an analysis of seven factors by surveying 40 respondents at PT. XYZ. The results obtained are three factors consisting of depth of communication, technology, and training which have an influence on the effectiveness of the application of virtual organizations at PT. XYZ, while four other factors such as trust, shared understanding of knowledge, commitment, and leadership have no significant effect on the effectiveness of virtual organizations.
技术的发展导致在一个组织中以虚拟组织的形式在地理上和时区上分别进行合作。PT XYZ的微软解决方案和服务(DMSS)部门是以数字服务一站式解决方案的形式提供数字服务的部门之一,包括内部部署和云基础设施模型,为客户提供基于微软产品的产品和解决方案。在2019冠状病毒病大流行期间,该部门实施了虚拟团队协调,使产品开发能够按计划进行。然而,另一方面,实施虚拟组织的绩效有效性仍然是公司面临的挑战。这是研究的重点,以找出哪些因素影响了虚拟组织在PT XYZ的应用,特别是在微软解决方案和服务部的合作有效性。本研究通过调查PT. XYZ的40名受访者,对7个因素进行了分析。得到的结果是,沟通深度、技术和培训三个因素对PT. XYZ虚拟组织应用的有效性有影响,而信任、对知识的共同理解、承诺和领导力四个因素对虚拟组织的有效性没有显著影响。

Sudoku is a game that sharpens the brain and is very well known. But the problem faced in this condition is how we can find a solution for the completion of this game. Problems with the Sudoku game can be solved by using the concept of Artificial Intelligence (AI). Some of the algorithms that can be used are the Breadth First Search (BFS) and Depth Limited Search (DLS) algorithms. The purpose of this research is to find a solution for Sudoku and make a comparative analysis of the search results of the two algorithms. The results obtained are application design in the form of a simulation of the completion of the Sudoku game problem with two algorithms. And it has been proven from the two algorithms that DLS is more efficient and faster than BFS. While BFS itself has advantages, in terms of a more structured and systematic search system that is able to find all possible numbers in each box. In this case, if a Sudoku question has more than one answer, then BFS will find it.
数独是一种让大脑变得敏锐的游戏,非常有名。但在这种情况下,我们所面临的问题是如何找到一个解决方案来完成这个游戏。数独游戏的问题可以用人工智能(AI)的概念来解决。可以使用的一些算法是广度优先搜索(BFS)和深度限制搜索(DLS)算法。本研究的目的是为数独寻找一个解,并对两种算法的搜索结果进行比较分析。所获得的结果是以应用程序设计的形式模拟了用两种算法完成数独游戏问题。两种算法都证明了DLS算法比BFS算法更高效、更快。虽然BFS本身有优势,就更结构化和系统化的搜索系统而言,它能够在每个框中找到所有可能的数字。在这种情况下,如果一个数独问题有多个答案,那么BFS将找到它。

The development of computer network technology in the form of Software Defined Networking (SDN), provides many facilities for users to be able to develop network control applications, which can separate the data plane function from the control plane. The existence of this separation on routers and switches makes it easy for developers to centrally develop software and devices according to what is needed by users. However, there were obstacles to implementing SDN on IP networks in a short time. For this reason, it is necessary to implement SDN in stages by adding SDN to the existing IP network in the form of SDN IP, so that SDN can be connected and exchange routing information autonomously. This study focuses on the design and implementation of SDN IP using the Open Network Operating System (ONOS) on the Border Gateway Protocol (BGP). The results show that the design and implementation of SDN IP based on ONOS and BGP can be done well, where SDN can connect and exchange routing information with the Autonomous System (AS) native BGP-based network.   Key word(s): Autonomous System (AS) Border Gateway Protocol (BGP) Open Network Operating System (ONOS) Software-Defined Networking (SDN) SDN IP
计算机网络技术以软件定义网络(SDN)的形式发展,为用户开发网络控制应用提供了许多便利,可以将数据平面功能与控制平面分离开来。路由器和交换机的这种分离使得开发人员可以根据用户的需要集中开发软件和设备。然而,在短时间内在IP网络上实现SDN存在障碍。因此,需要分阶段实现SDN,以SDN IP的形式将SDN添加到现有的IP网络中,使SDN能够自主连接并交换路由信息。本研究的重点是在边界网关协议(BGP)上使用开放网络操作系统(ONOS)设计和实现SDN IP。结果表明,基于ONOS和BGP的SDN IP可以很好地设计和实现,其中SDN可以与自治系统(Autonomous System, AS)本地基于BGP的网络连接并交换路由信息。关键词:自治系统(AS)边界网关协议(BGP)开放网络操作系统(ONOS)软件定义网络(SDN) SDN IP

Humans are living things that have 60 trillion cells to build the body, each cell of the human body contains 70% more water. Humans need water that is suitable for consumption. Water that is fit for consumption is water that has been processed or without processing that has met the requirements and can be drunk immediately. Various factors can cause water quality to decline, one of which is a water container in the form of gallons of water. From the results of a survey of students, 69.2% of students stated that drinking water on campus was not adequate. Meanwhile, 16.9% stated that it was not suitable and 13.8% of the other students stated that drinking water was suitable for consumption. So that the control system is modified on the existing devices so that they can work more effectively and efficiently. Furthermore, the research data was taken using quantitative data analysis techniques with descriptive statistics and the calculation of the average relative error. In the resulting data, the relative error value of the working time variable is 0.51% and 17.2% of the variable delay. And the relative variable error value is 18.3%. For the level of particle content in water in gallon 1 an average of 54 mg / L with an average temperature of 27.44 ° C and in gallon 2 of 52.6 mg / L with an average temperature of 28 ° C.
人类是有60万亿个细胞组成身体的生物,人体的每个细胞含有70%以上的水。人类需要适合饮用的水。适宜饮用的水是指经过处理或者未经处理,符合要求的,可以立即饮用的水。各种因素都会导致水质下降,其中之一就是以加仑水为形式的水容器。根据一项对学生的调查结果,69.2%的学生认为校园里的饮用水不足。同时,16.9%的学生表示不适合饮用,13.8%的学生表示饮用水适合饮用。从而对现有设备的控制系统进行改造,使其能够更有效地工作。此外,研究数据采用定量数据分析技术与描述性统计和计算平均相对误差。在得到的数据中,工作时间变量的相对误差值分别为可变延迟的0.51%和17.2%。相对变量误差值为18.3%。1加仑水的颗粒含量平均为54毫克/升,平均温度为27.44°C, 2加仑水的颗粒含量为52.6毫克/升,平均温度为28°C。

Humans need water that is suitable for consumption. Water that is fit for consumption is water that has been processed or without processing that has met the requirements and can be drunk immediately. Various factors can cause water quality to decline, one of which is a water container in the form of gallons of water. From the results of a survey of students, 69.2% of students stated that drinking water on campus was not adequate. Meanwhile, 16.9% stated that it was not suitable and 13.8% of the other students stated that drinking water was suitable for consumption. So that the control system is modified on the existing devices so that they can work more effectively and efficiently. Furthermore, the research data was taken using quantitative data analysis techniques with descriptive statistics and the calculation of the average relative error.
