Purpose: Twitter related to mental health has great potential as a medium to provide important information to the public and health organizations on a large scale, but an evaluation of tweet data related to mental health disorders has not been carried out. This study aims to classify tweet data to determine the most common mental health disorders in Indonesia based on the symptoms experienced.Methodology: The classification process is carried out using cosine similarity calculations between tweets data and keywords which are compiled based on theoretical studies and optimization of the LDA topic modeling results.Findings/result:The classification results show that the most discussed issues on Twitter are depression, bipolar, schizophrenia, dementia, and PTSD. Based on these results it can be interpreted that the level of prevalence and public attention to depressive diorders is quite high compared to other disorders. From the results of the classification, it is also possible to identify the most discussed symptoms throughthe emergence of keywords from each category.Originality: Classification is calculated based on the cosine similarity between tweets and keywords compiled from human judgement and enriched using the results of LDA topic modeling to improve classification performance

Purpose: This study aims to conduct a load testing using JMeter and then analyze the performance of the FastAPI framework on the backend of the lost circulation handling management application in oil well drilling. The developed API receives input in the form of drilling parameter data (daily drilling report) from drilling engineers to be processed by a machine learning model (prediction and classification) through the FastAPI framework. The developed API returns processing data in JSON format.Methodology: Performance measurement is done by conducting load testing simulations using the help of JMeter software. Load testing scenarios are created by varying the number of users and ramp-up time, as well as the method of loading the machine learning model used (normal or preemptive loading). The parameters measured in the test scenario are average execution time, maximum execution time, error percentage, and request throughput.Findings: Load testing on a FastAPI-developed API demonstrated that for compute-heavy tasks like machine learning inference, increasing the number of processor cores and using preemptive model loading led to significantly better performance improvements than changes in processor clock speed or switching from HDD to SSD. Even when simulating a higher user load than initially expected (up to 250 users/threads), FastAPI maintained good response times and a low error rate, remaining below 20%.Originality/value/state of the art: This study result is an information about the performance of the FastAPI framework in the application of lost circulation handling management in oil well drilling in the deployment phase, not only up to the model testing phase as in previous studies.

Bangunsari Health Center in providing services implements various stages of the process that must be passed. Among them is the registration process, where many patients often do not get a queue number because there are restrictions in certain poles every day. In the registration process, patients must submit identities such as Name, NIK, Date of birth, address and telephone number. This data is sensitive information that must be kept confidential, especially since the data is increasing every day. Therefore, to overcome these problems, namely through the development of a website-based patient queuing system by applying an encryption algorithm. With the aim that it will be useful to simplify the queuing process and secure the private data to avoid misuse and data leakage, by going through the data encryption or cryptography process. Cryptography is the science and art of maintaining the confidentiality of messages by encoding them into a form that is no longer understandable in meaning. Data encryption has several algorithms that can be used, one of which is the Base64 algorithm, the Base64 algorithm can be useful in encoding binary data so that it turns into a format that can be printed normally into ASCII format based on the number 64. To ensure that the website-based patient queuing system runs according to the flow that has been made, it is tested using the black box method with the results of the entire system functioning and running according to the source code that has been designed. Meanwhile, the results of implementing base64 run according to the rules that have been tested using the whitebox method and the base64 decode web site, with the results of whitebox and base64 site testing, it is known that the data results are encrypted in the database. So that if there are intruders who enter the database, they cannot read the data that has been encrypted in the form of random text in it.
