<![CDATA[Nowadays, decision support systems have gained wide popularity not only in private companies but also in government sectors. These systems play a crucial role in assisting leaders during the decision-making process. The effective functioning of the government heavily relies on employee performance, which requires discipline in carrying out their duties and responsibilities. Employee discipline is closely linked to their attendance, including leave-taking. Therefore, analyzing employee leave data can reveal trends and interrelationships, providing leaders with valuable information and insights for determining employee leave policies. To address this issue, data mining applications such as the Light Gradient Boosting Machine (LightGBM) regression prediction model can be utilized. This model takes into account factors like gender, age, and the starting year of leave to predict the number of employees who take annual leave simultaneously with holidays. Additionally, clustering algorithms like K-Means can be employed to group reasons for leave into clusters, identifying common leave patterns among employees. In this study, employee leave application data from January 2018 to July 2022 was collected from the Leave module within the HRIS (Human Resource Information System) application. The research outcomes encompass a dashboard visualization presenting descriptive analysis and modeling using LightGBM. The modeling results yielded reasonably accurate predictions, as evidenced by model testing that showed a difference of only 1 employee. Additionally, K-Means clustering formed 4 clusters of leave reasons, with the majority being family-related, illness, childcare, and elderly care. The dashboard can be used by management as a consideration for approving employee leaves, ensuring well-planned leave scheduling for the following year and minimizing disruption to work execution in each department.]]>

<![CDATA[During the COVID-19 pandemic, more community activities were at home with government policies to limit people's movements, especially in urban areas. During the period of restrictions on people's movements due to COVID-19, it was also followed by new habits, namely activities around the house, one of which was the increasing trend of Urban Farming to fill time. However, after the pandemic began to experience a downward trend, people no longer cared for their plants due to activities that had returned to normal. In this research, the design of Internet of Things technology was carried out to help urban communities to monitor and control plants so that people continue to carry out their daily activities without worrying about their plants running out of water. This study uses the NodeMCu V3 microcontroller as the data receiving center at the hardware layer and then a DHT 11 sensor is needed for temperature monitoring, a Soil Moisture sensor for monitoring soil moisture, a raindrop sensor for monitoring rain conditions as well as relays and a mini pump to control the water needs of plants. The results of this study are that the IoT device successfully displays temperature data, soil moisture data, rain status and automatic plant watering controls function properly if the value on the soil moisture sensor is below 25. The data communication path in this study uses the MQTT protocol using a webserver from Adafruit IO with an average packet loss of 0.20%. With the functioning of all the components on the created IoT device, the community can apply an IoT-based Smart Garden in urban farming so that plant maintenance can still be carried out.]]>

<![CDATA[Central Government, is a government agency that manages important and confidential state data and information. The data that is managed needs to be maintained for reliability and security in order to avoid the risk of loss, leakage and misuse of information. To maintain this data, an optimal information security device is needed. Information security tools used today have a variety of functions resulting in many important logs that must be managed, analyzed and evaluated. The log data from each of these information security devices is still separate and must be processed manually to obtain simpler and more efficient data so that it can be monitored and presented to management. The purpose of this research is to make the right data warehouse modeling in order to assist in the process of presenting information quickly and accurately related to the processing of data logs of information security devices as a report that will be given to management in support of the Zero Tollerance data security policy. The method used in designing this data warehouse is using the Kimball 9 step method. The results obtained are in the form of a starflake schema and a data warehouse log of information security devices consisting of a malware fact table, intrusion facts and attack facts that can be used as centralized data monitoring that will be implemented at the Security Operation Center. Testing is done using Pentaho software tools. This data warehouse is expected to provide a quick, accurate, and continuous summary of information so that it can assist management in the decision-making process and policy making for the future.]]>

<![CDATA[The need for digital data security is to ensure that the data and information we have are confidential and can only be accessed by authorized users. And no one can change the information in it, thus ensuring complete accuracy. The functions of data security are confidentiality, authentication, integrity, and anti-repudiation. Compression techniques are used to protect digital data because they aim to make less storage space and allow us to transfer more data over the internet. This study aims to plan to prove the application of a combination of 2 (two) techniques, namely compression and cryptography to digital data with the aim of increasing the security of the data. This research has the result that the compression technique of the Huffman method is the most effective in compressing digital data into the smallest file size compared to other compression methods. It can compressed the data size by around 30% (thirty percent) to 40% (forty percent) compared to the original data size. And coupled with data security with cryptographic encryption techniques so that files remain safe when transferred over the network.]]>

<![CDATA[The process of controlling irrigation doors in fishponds is still mostly done manually, this results in the performance of farmers being less effective and efficient. Current technological developments, especially in the field of IoT, can be used to design a simulation that is able to control irrigation gates automatically. Based on the results of the tests that have been carried out, it can be concluded that the ATmega16-based automatic irrigation gate simulation tool can work well according to the designed working principle. If the condition of fishpond water is less than the ideal height of the fishpond and the condition of river water is more than the height of the fishpond, the motor will move to "open" the irrigation door to fill fishpond water. If the fishpond water condition is more than the ideal height and the river water condition is less than the fishpond height, the motor will move to "open" the irrigation door to discharge fishpond water and if the river water condition is the same as the fishpond water condition, the motor will move "close” the irrigation door so that the ideal height of the fishpond can be achieved. There are certain conditions to control the door manually using the SMS Gateway. Information about the maximum or minimum fishpond water level will be displayed on the LCD to determine the maximum or minimum fishpond height using Keypad.]]>

<![CDATA[In a company, information technology is needed, especially computer networks, to facilitate data communication. The management of a computer network, of course, requires good administration. The criteria for whether or not a network is good can be seen from the performance, reliability, and security indicators so that it will not cause network issues. Events such as server downs, data loss, lost connections, and undetected computers cause the organization's business performance to be disrupted. This study's purpose is to detect network issues with network programmability technology automatically. Paramiko library supports network automation systems and implements OSPF routing protocol in finding the shortest path to send network packets. This study uses the PPDIOO flow, namely prepare, plan, design, implement, operate, and optimize, because it is considered by the flow of making network detection tools. The results showed that the design and implementation of a small-scale network were successfully built by utilizing network programmability technology and the paramiko library, which helps detect network conditions at any time. This design has a dashboard, provisioning, assurance, and policy features that allow administrators to manage and monitor information on each network device. The network design is fitted with REST-API technology and security through a secure shell (ssh) from the Network Controller that can detect the device's connection conditions and the device's health and update the DNS configuration used. Network Issues that have been seen are devices being down, and the connection being lost. Future research can improve features for network troubleshooting when the connection is lost.]]>

<![CDATA[Information security is an asset that has value so it must be protected, along with increasing assets it is undeniable that many people wish to gain access and control it so that behind the convenience in the digital world there are many risks to information assets. There are several cases that occur related to information security such as data theft, illegal access, information leakage and vandalism where this becomes the privacy of the user. So it is necessary to do research from the user's perspective to measure the level of information security and privacy awareness of students and lecturers as well as recommendations that will be suggested based on the results of measuring information security and privacy awareness. The objects in this research are students and lecturers at the XYZ University. The method used is Multiple Criteria Decision Analysis (MCDA) by measuring the dimensions of knowledge, attitude, behavior in six areas of information security and three areas of privacy. Data were obtained by distributing questionnaires using a Likert scale of 5. Based on the questionnaire from the respondents, it can be seen students and lecturers have awareness that is at a "good" level of 85% in information security while privacy is at a "good" level with a result of 89% but in the behavior dimension there are several areas that are included in the "average" level including the area passwords by 62%, mobile equipment area by 77% incident area by 70% and on privacy security on the behavior dimension there is one area namely the login activity area by 78% so this needs to be given recommendations for improvement in order to reach a "good" level by providing socialization/ training for students and lecturers]]>
