<![CDATA[The application of health protocols has become a new habit in the Covid-19 pandemic, one of which is the use of masks. Presidential Instruction Number 6 of 2020 on August 4, 2020, has stipulated the obligation to use masks in Indonesia. This study aims to determine the topics formed on the Twitter network and public perceptions before and before the implementation of the Presidential Instruction. Tweet data with the hashtags “#gunakanmasker” and “#indonesiaterserah” were collected during the period from March 2 to November 30, 2020. The data was processed using the Topic Modeling method with Python software. The results show that the topics formed before the Presidential Instruction were "prevent-protect" and the topics after the Presidential Instruction were "compulsory-mandatory". The Chi-Square test shows that the topics formed before and before the implementation of the Presidential Instruction are independent. The topics that were mined from the tweet data were then checked for compliance with the policy framework consisting of the variables of perceived knowledge, social trust, perceived benefits, and perceived risks]]>

<![CDATA[Information Technology (IT) develops to support all activities within the company. One of these information technologies is an information system, an information system for calculating employee overtime wages at PT. Metal Castindo Industritama. In the process of applying for overtime, current employees take a long time and a long process. One of them is by filling out an overtime application form or commonly called an Overtime Work Order (SPKL) for each overtime employee, considering that the number of employees working overtime at the same time is not small. One of the problems is errors that often occur when calculating the total overtime pay for employees. To overcome this challenge, we need a system that simplifies the process of reporting employee overtime data and calculating employee overtime pay quickly and accurately. This research begins with an ongoing system analysis, obtained through direct interviews with stakeholders and field observations. The software development model uses the waterfall model, and the design method uses UML to describe the system design. The purpose of this system is to create a simple and accurate system for submitting employee overtime hours and calculating employee overtime wages so that there is no need for a long procedure. In addition, the performance of superiors is more effective and efficient because of the computer-managed website-based information system. The data is stored in the database system, so the whole process does not require a lot of paper]]>

<![CDATA[PT PLN (Persero) as a state-owned company with a business in the electricity sector is always trying to improve the quality of service to customers. One of the efforts made is to develop an existing application platform, namely PLN Mobile into New PLN Mobile. As a development from the previous application, PLN has added features for requesting new installation services, changing power, and applying for tariff changes in the New PLN Mobile application. However, with the addition of a new feature, namely the PLN service request feature in the New PLN Mobile application, it will change the PLN service business process that has been running for years. Changes in business processes will affect customer habits in applying for PLN services. This study aims to determine how customer acceptance of the service request feature in the New PLN Mobile application is measured through the intensity (perceived usefulness) and ease of use of the customer. The method used in this research is the distribution of questionnaires followed by statistical analysis using the Technology Acceptance Model (TAM) 3. TAM is a statistical method that combines technology acceptance with a structured equation model. The results obtained are Perceived Usefulness (PU) is influenced by Subjective Norm (SN), Job Relevance (REL), Output Quality (OUT) and Result of Demonstrability (RES), while Perceived Ease of Use (PEOU) is influenced by Perception of External Control (PEC), Computer Anxiety (CANX), Computer Playfulness (CPLAY) and Perceived Enjoyment (ENJ), then Behavioral Intention (BI) is influenced by Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) and Use Behavioral (USE) is influenced by Behavioral Intention (BI). This research is expected to provide input in developing the New PLN Mobile application and improving the quality of PLN services in the future.]]>

<![CDATA[Islamic boarding schools are one of the traditional educational institutions that study Islamic values daily, the selection of student scholarships still uses manual so that it will affect the results of scholarship selection and data input still uses handwriting so that storing files for a long time is likely to be damaged due to exposure to water. or torn, it is necessary to create a system that helps the scholarship selection process using the AHP (Analytical Hierarchy Process) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods. In AHP there are 4 (four) stages, including: determining the criteria, determining the pairwise comparison table, calculating the criterion value matrix and the consistency ratio. The criteria used refer to the requirements for the selection of students at the al-Madani Islamic boarding school. AHP is used to calculate the weight of each criterion and TOPSIS for ranking, the first step is to calculate the AHP method by inputting criteria and determining pairwise comparison tables to produce weights between criteria. The TOPSIS implementation includes: alternative data, alternative assessments, weighted normalization, determining positive and negative ideal solutions, and calculating the distance of positive and negative ideal solutions so as to produce a ranking, a decision support system for selecting outstanding santri scholarships with the highest preference value, namely: 0.69123910870266 so that the results This can be a benchmark for scholarship recipients based on predetermined criteria.]]>

<![CDATA[Smart Indonesia Program Assistance is educational assistance provided by the government to elementary, middle and high school students aged 6-12 years. The Smart Indonesia Program is an improvement from the previous government program, namely Assistance for Poor Students. This assistance is one of the existing aids at the MI Salakopi school, but the school is still having difficulties in determining the students who are entitled to the Smart Indonesia Program (PIP). This problem is due to the same criteria and the selection is still manually by the school operator. In addition, in previous studies, there were several similar rankings, of course reducing the level of objectivity and accuracy of research based on the results of direct observations of prospective beneficiaries. The combination of the Fuzzy Topsis method is expected to provide a solution, especially in reducing the same ranking data so that the accuracy of objectivity is better. The Fuzzy Topsis method can reduce the results of the same ranking to 46%. The final result of the calculation using Fuzzy TOPSIS which was tested on 15 alternatives with the highest value of A12 of 0.658]]>
