This systematic review article encompasses 515 publications and screens narrowed down to 97 articles by the criteria of inclusion and exclusion. It concludes that three main problems exist for energy-saving home applications: 1) experts and non-experts do not understand the energy efficient home data presented, 2) they are not designed for middleaged and elderly users, and 3) the graphic communication is difficult to understand. Therefore, the aim of this article is to outline the issues, research gaps, and guidelines pertaining to the development of energy-saving home applications that are accessible, usable, understandable, and desirable for all users. Related review articles were analyzed by researching the correlation of three variables: application, user-centered design (UCD), and energy data. In summary, user experience, user interface, and UCD are recommended to optimize the design of accessible energy-saving home applications.

The rapid development of application-based transportation services has brought about the emergence of various platforms, including 'My Tuc-Tuc,' a specific transportation service developed by Telkom University. However, the operation of 'My Tuc-Tuc' has faced several challenges, particularly concerning user experiences, especially among drivers. Therefore, this study aims to assess the technology readiness of 'My Tuc-Tuc' users, focusing on their readiness across four personality traits: optimism, innovativeness, anxiety, and insecurity. These traits encompass both positive and negative perspectives. The study employed the Technology Readiness Index (TRI) methodology, a well-established framework for evaluating users' readiness to adopt and utilize technology. The selection of participants involved utilizing the Slovin formula, resulting in a sample size of 12 'My Tuc-Tuc' users who also served as TelU Car drivers. Rigorous validity and reliability tests were conducted to ensure the accuracy and consistency of the collected data. Subsequently, the TRI scores were calculated based on the participants' responses. The findings of the study revealed a TRI score of 3.9098, indicating that 'My Tuc-Tuc' users fall within the high technology readiness category according to the TRI classification. This suggests that these users are well-prepared and receptive to the utilization of the 'My Tuc-Tuc' application-based transportation service. The results provide valuable insights for Telkom University and the 'My Tuc-Tuc' team, enabling them to identify and address the challenges faced by users and develop appropriate strategies to enhance the overall user experience and service quality. This study contributes to the existing literature on technology readiness and offers practical implications for the further development and improvement of 'My Tuc-Tuc' as a reliable and user-friendly transportation service. Future research endeavors could explore additional dimensions of technology readiness and examine factors influencing user satisfaction and loyalty, thereby providing a more comprehensive understanding of user behaviors and preferences in the context of application-based transportation services.

Analysis of influences line in structures that are complex or indeterminate will make the analysis difficult and time-consuming. Therefore, the researchers have developed an application to analyze beam structures in 2 dimensions that easy to use, convenient, and uncomplicated. In this research, the Double integration method and the Singularity function method are used to analyze the structure. Furthermore, Python is used to develop all of the instructions in Object-oriented programming (OOP) application development. The developed application is capable to analyze the influence lines of structures and display the results in form of animation to show load displacement and structural response. Moreover, it was incorporated with analysis to show basic structural diagrams such as bending, shear, and deflection diagrams. In the final word, this application will be a handy tool for better visualization and investigation behaviors of structures in actual design work.

This review presents the extractions, characterisations, applications and economic analyses of natural coagulant in separating pollutants and microalgae fromwater medium, known as microalgae harvesting. The promising future of microalgae as a next-generation energy source is reviewed and the significant drawbacks of conventional microalgae harvesting using alum are evaluated. The performances of natural coagulant in microalgae harvesting are studied and proven to exceed the alum. In addition, the details of each processing stage in the extraction of natural coagulant (plant, microbial and animal) are comprehensively discussed with justifications. This information could contribute to future exploration of novel natural coagulants by providing description of optimised extraction steps for a number of natural coagulants. Besides, the characterisations of natural coagulants have garnered a great deal of attention, and the strategies to enhance the flocculating activity based on their characteristics are discussed. Several important characterisations have been tabulated in this review such as physical aspects, including surface morphology and surface charges; chemical aspects, including molecular weight, functional group and elemental properties; and thermal stability parameters including thermogravimetry analysis and differential scanning calorimetry. Furthermore, various applications of natural coagulant in the industries other than microalgae harvesting are revealed. The cost analysis of natural coagulant application in mass harvesting of microalgae is allowed to evaluate its feasibility towards commercialisation in the industrial. Last, the potentially new natural coagulants, which are yet to be exploited and applied, are listed as the additional information for future study.

The purpose of this project is to develop Parents and Teachers Communication (PTC) application for early childhood. An application development process has three phases. The first phase is application design phase: the questionnaire had been used to investigate the main requirements from the users (teachers and parents). The application’s function comparison was another method which had been applied in design phase. Five school communication applications had been compared to find for strong features in each application. Human factors engineering was used for designing PTC application’s user interfaces in order to understand user capabilities and limitations. The second phase was application coding phase: PTC application was developed under IOS operation system by using the X-CODE program. The third phase was application usability study phase: in this phase, the usability study test was measured in two steps. First, the System Usability Scale (SUS) was distributed to 10 volunteers during application development. Second, another usability test was done by an adopted SUS questionnaire. It was distributed to 6 volunteers after they had experience with PTC application about two week period. Results showed that PTC application had high usability scale during application development (SUS, 85) and after four weeks experience (adopted SUS, 80). SUS during application development showed that PTC application was in excellent usability scale. The adopted SUS questionnaire can be interpreted that users have a great experience with PTC application. Parent-Teacher communication application for early childhood could assist to decrease cap of communication between home and school efficiently.

This paper explores a physical activity monitoring application in smartphones. The combination of smartphone application and sensors could perform as a biomedical sensor to monitor physical activities. Thai 3 Axis (TH3AX) was developed as a real-time physical activities monitoring application such as standing, walking, and running. The smartphone was attached to right hip of 10 young, healthy adult subjects to collect accelerometer data to determine threshold range for each activity. After finding thresholds, the results were used as range for a predictive model of activity recognition. The second experiment was scheduled with 6 young healthy subjects performed three physical activities (standing, walking, and running) to evaluate TH3AX application. Then, a diagnostic test was computed to test TH3AX's sensitivity, specificity, and accuracy. Results showed that TH3AX sensitivity, specificity, and accuracy are 0.981, 0.988, and 0.986, respectively.
