This study explores the development and evaluation of a Variational Quantum Algorithm (VQA) for predicting a drug as a corrosion inhibitor, highlighting its advantages over traditional regression models. The VQA leverages quantum-enhanced feature mapping and optimization techniques to capture complex, non-linear relationships within the data. Comparative analysis with AutoRegressive with exogenous inputs (ARX) and Gradient Boosting (GB) models demonstrate the superior performance of VQA across key metrics, including Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Deviation (MAD). The VQA achieved the lowest RMSE (4.40), MAE (3.33), and MAD (3.17) values, indicating enhanced predictive accuracy and stability. These results underscore the potential of quantum machine learning techniques in advancing predictive modeling capabilities, offering significant improvements in accuracy and consistency over classical methods. The findings suggest that VQA is a promising approach for applications requiring high precision and reliability, paving the way for broader adoption of quantum-enhanced models in material science and beyond.

The community service program in Kartikajaya Village aims to develop local economic potential through mangrove planting as a tourist attraction. Kartikajaya Village has geographical conditions that support the development of ecotourism, but the lack of public awareness and understanding of the benefits of mangroves is a major obstacle. This activity involves local communities in the process of planting and maintaining mangroves, as well as providing education about the importance of mangroves in maintaining the balance of coastal ecosystems and increasing village tourism attractiveness. The results of this program showed an increase in community awareness of environmental conservation as well as an increase in tourist visits to the village. Thus, mangrove planting not only serves as an environmental conservation effort, but also as a driver of economic growth through the tourism sector in Kartikajaya Village.

An English folksong entitled The Wellerman became popular in Indonesia recently. Therefore, the accuracy and acceptability in folksong were important to be investigated. This paper reported the accuracy and acceptability of English into Indonesian translation in a folksong entitled The Wellerman. This research applied descriptive qualitative method. In addition, this research combined with purposive sampling technique. Nababan translation quality assessment framework was used to investigate the accuracy and acceptability of the folksong. The whole The Wellerman’s lyrics consist of 28 lines which was then assessed by the raters in terms of its accuracy and acceptability. The raters were 2 translators and 1 writer. The raters were purposely chosen to conduct reliable results of the accuracy and acceptability. This study found the average score of the accuracy was 2. 35 with 198 total scores and the average score of the acceptability was 2.48 with 209 total scores. The result indicates that the translation was relatively accurate and acceptable for the raters. However, it needs further improvement to maintain the context of the source text (ST) in the target text (TT) to reach an accuracy and acceptability in The Wellerman folksong. This study implied that it is crucial to maintain the imagery, narration, and the context of folksong translation.

Several factors influence PV output, including irradiance, temperature, and panel tilt angle. Irradiance and tilt angle affect the Photovoltaic (PV) current, while temperature affects the PV voltage. To accurately measure the performance of PVs in the field, it is necessary to condition these three parameters. Therefore, a system should be created to condition these parameters. This research aims to develop a control and monitoring system based on the set point to condition irradiance, temperature, and tilt angle. This research started with system design, fabrication, functionality testing with the black box method, sensor reading accuracy, and PV performance testing. The functionality testing results indicate that each test item can perform as expected. The sensor testing revealed of 1%, 0.26%, and 1.8% errors for MLX90614, BH1750, and MPU6050, respectively. The system's performance was tested, and it was discovered that the input value, which is the setpoint of the three variables, i.e., irradiance, temperature, and tilt angle of the PV, can produce outputs that are almost the same as the input value and settling time is different to reach the setpoint of each parameter. PV performance measurement using this system can represent PV performance by conducting direct testing using direct sunlight.

The use of social media has increased in the last few years. Social media has a negative impact on a person's self-esteem because they make social comparisons based on what they see on social media. This study aims to examine the relationship between the level of social media use and the level of self-esteem in young adults. The study used a cross-sectional approach, and the population in this study was college students (19-20 years old) in Malang, Indonesia. The sample consisted of 96 respondents, selected using purposive sampling. Respondents filled out the Bergen Social Media Addiction Scale (BSMAS) questionnaire and the Coopersmith Self-esteem Inventory (CSEI). Data were analyzed using the Spearman Rank correlation test in SPSS. The results showed that 57.3% of respondents were at the alert category level of social media use, and 63.5% of respondents had very low self-esteem. The correlation test showed a negative relationship between social media use and self-esteem (p-value = 0.044; r = -0.206). The strength of the relationship is weak and has a negative direction, meaning that the higher the level of social media use, the lower the self-esteem level will be. Alert-level social media use among young adults has an effect on low levels of self-esteem.
