Abstract:
The business process of an organization can’t be done properly without appropriate information management, in which information is an important asset that needs to be protected with the utmost care and concern. Information security is a way to protect information from large scale threats, thus to ensure the sustainability of the organization's operational, to reduce business risks and to increase business opportunity and return of investment. This research is conducted to measure the accountability of ISO 27001 in assisting the organization to document the information security policy. ISO/IEC 27001:2005 is a standard of information security that is widely used, openly accepted and implemented, and suitable for providing rules related to implementation and evaluation of the information security system. The assessment from ISO controls and objectives will be converted into a triangular fuzzy number to help in the analysis purpose. The fuzzy number is used to simplify the measurement. The result shows that the organization is not yet complying with the standard procedures of the Information Security Management System so it is needed to document the security policy based on the ISO 27001 framework standard.

Abstract:
The problem that occurs at the Karawang National Narcotics Agency (BNNK) is that there is no information regarding existing asset data, both from the name of the item, year of acquisition, item code, and item serial number. Therefore, the author will create a QR code that contains information about the items in BNNK so that it can be easily accessed and information about these items can be known and can make it easier for employees there when the Ministry of Finance will audit the items related to assets at the BNNK office. Therefore, this study proposes a research related to asset management using a QR code for items at BNNK. The method used in making this QR code is using the QR generator method to simplify the process of making QR codes and making designs for QR codes that will made. For testing the QR code we use beta testing so that we can know in advance the performance and output generated by the QR code. This study produces a QR code that is in accordance with the request of related parties and makes it easier for employees in the goods section to find out data about assets owned by BNNK and help BNNK to carry out asset management on items in the office.

Abstract:
Since the emergence of the Covid-19 virus in Indonesia, learning activities in the education system have been changed to distance learning using online media. The most widely used application according to the results of interviews with teacher representatives from 4 vocational schools in Karawang Regency is Google Classroom. However, the application received a poor rating based on the rating on the Google Play Store. So that usability testing is carried out in order to assess the effectiveness, efficiency and user satisfaction of the application. There are several usability testing techniques, including (SUS) System Usability Scale and Usefull, Satisfaction and ease of Use (USE) Questionnaire. This study aims to obtain the results of usability testing and a comparison between the two techniques used. Both have some similarities where the analysis can be done using any media, it's just that there are differences in the number of questions and data analysis. The System Usability Scale (SUS) technique contains 10 questions while the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique contains 30 questions with 3 main dimensions, namely Usefulness, Satisfaction and Ease of Use. The research method used is Product Moment Pearson’s method for data validity analysis and Cronbbach's Alpha method for data reliability analysis. This research is a quantitative descriptive study conducted on 50 high school students/equivalent and university students. The results of the questionnaire technique (SUS) System Usability Scale state that Google Classroom has a good interface with a score of 72 with advantages in ease of use and desire to use it again, while based on the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique states Google Classroom has an average value of 84% with 81% (usefulness), 86% (ease of use), 87% (ease of learning) and 83% (satisfaction). Then according to the comparison, the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique is stated to be better with a reliability value of 0.967 while (SUS) System Usability Scale only has reliability (0.634).

Abstract:
With the presence of a marketplace, internet users are able to shop by cellphones or laptops which ease them to process the transactions. This advantage is the key to the popularity of e-commerce and marketplaces in the 21st century. Considering that users prefer having e-commerce to going out and looking for products. Internet users are still hesitant in choosing a good and bad marketplace since there is a disappointing marketplace system and a deficient service. The Researcher will make a selection of the product marketplace based on opinions or review comments. The stage of selecting marketplace products is based on an opinion or public opinion who buys goods on the selected marketplace, the opinion is given into online opinions such as comments on the marketplace. The comments that are used as samples will be processed and grouped into data sets. In this case, the researcher processes the classification or grouping of data by applying the Support Vector Machine (SVM) method in accordance with the classification of processing data sets in the form of text. After being applied to the SVM method, the accuracy value is 75.92%, the SVM method produces a fairly good accuracy value on the dataset in the form of text classification in the marketplace review. From the results of testing the data, it can help readers in determining a good marketplace.

Abstract:
Increasingly, the amount of data in the form of text documents scattered on the internet is getting bigger. It took a very long time to get the information from each of these documents. For this reason, several researchers developed the Automatic Text Summarizer to summarize text automatically, so that the time needed to get important information from the entire document can be faster. Research that focuses on automatic summarization of Arabic texts is very rare. In fact, there are more than 300 million Arabic speakers in the world and Arabic is the official language at the United Nations. Therefore, this study develops a model that can perform text summarization automatically using the TextRank algorithm. The test results using Q&A Evaluation show very good results with details of the suitability of the summary results with the original text by 90%, the suitability of the summary results with Arabic grammar is 91.43%, the suitability of the summary results is 90%, the ease of understanding the summary results is 90%. and the useful aspects of the model developed were 91.43%.

Abstract:
The majority of farmers are still unsure of which vegetable seeds are appropriate for planting on this property. This is due to farmers' lack of understanding of the conditions for planting these vegetable seeds on their fields. Due to farmers' and the general public's lack of understanding of land suitability evaluation, vegetable seeds have not been planted with optimum results because the requirements required for these vegetable crops do not match the land conditions that sustain vegetable growth. Understanding the significance of choosing vegetable seeds based on the adaptability of selecting land and plants also relies solely on farmers' scant knowledge. As a result, the authors believe that more research is needed to decide the best vegetable seeds for cultivation based on soil suitability and plant growth requirements. The AHP approach is very analytical and well-suited to determining the priority weight of each norm, which will later be used as a rating reference by the TOPSIS method. Based on the degree of soil suitability and the conditions for proper growth, it can be calculated that vegetable seeds will be planted later as an alternate, accurate, and dynamic approach

Abstract:
Telecommunication is one of the fastest growing industrial sectors so that there are more telecommunication companies. This can create various threats if the company does not use the strategy properly. Customer churn refers to the level of customer reduction which is one of the threats to reducing the company's revenue. This is an important issue for developing companies to evaluate in order to reduce the potential for churn that occurs. The initial stage that needs to be done is to predict customers who have the potential to switch from the company, one of which is the data mining approach. Classification is a data mining technique that can predict the class of datasets with various existing classification algorithms. The purpose of this study is to identify the effect of the number of dataset records on several classification algorithms. This research was conducted based on the CRISP-DM method by applying three classification algorithms, namely Logistic Regression, Naïve Bayes, and Decision Tree C4.5. The results showed that the greater the number of records in the dataset, the higher the accuracy value will be obtained. In dataset-1, logistic regression is a better algorithm based on an accuracy value of 80.09%, while naïve Bayes is superior based on an AUC value of 0.733 and an execution time of 0.00798 seconds. In dataset-2, it is found that decision tree is an algorithm that is more suitable than logistic regression and naïve Bayes algorithms, with an accuracy of 91.9% and an AUC value of 0.846 which is included in the good classification criteria. However, in execution time, the naïve Bayes algorithm only takes a processing time of 0.00403 seconds.

Abstract:
Junior High School 3 Patokbeusi is one of the schools that implements Teacher Competency Assessment one by one for the school year. In the assessment, the problem that is often an obstacle is the assessment process which is very complicated if it has to be done manually and the possibility of errors in calculating the value and recapping the value is more vulnerable. This is what makes the Teacher Competency Assessment process ineffective and inefficient. Based on the problems that have been described, it is necessary to make a solution to overcome the problems of Teacher Competency Assessment by making a web-based system application using the Analitycal Hierarchy Process (AHP) method. The process of determining this ranking uses the weights of the 14 criteria tested and is used to determine the highest alternative assessment value or the highest teacher competency value based on 14 pre-determined criteria weights. In this decision support system, it produces a value that is used as a problem-solving tool in determining the best performing teacher which has been done manually by the school. The results of this thesis research produce a web-based teacher competency assessment decision support system. Then to test this program, the authors use blackbox testing, whitebox testing and questionnaires where this questionnaire is a form filling stage by teachers and friends to assess the feasibility level of this program where the results of filling out the questionnaire form produce an overall score above 75. and is included in the “Very Good” rating, so it can be concluded that the teacher competency assessment decision support system program is worthy of being used as a process to determine the best teacher.

Abstract:
Geospatial Information System (GIS) is an information system that helps map events on earth to be analyzed with the help of computers. This GIS can make it easier to manage geographic information systems. Based on the results of an interview with the unit manager of the vice-chairman III of STT Terpadu Nurul Fikri, that currently, cannot map and see the visualization of the alumni's work field by the study program. Now, the vice-chairman III unit only can display information data with the help of Microsoft Excel. This study aims to build a Geospatial Information System with the ArcGIS application, making it easier to manage alumni and carry out tracer studies. If this data is available, it will be easier to maintain the relationship between alumni and the STT Terpadu Nurul Fikri. Good alumni data management will also open ample opportunities for collaboration, such as internships, jobs, graduate offers, and information on events and promotions. The results of the evaluation of the information presented were 81.25%, which meant that Deputy Assistant III had agreed with the presentation of data on the distribution of work locations for STT-NF alumni using ArcGIS 10.5. Based on determining the point of work location for STT-NF alumni, it was found that 89% of alumni work in the information technology sector and that their work locations are in the Greater Jakarta area.
