The remote-control system on this Unmanned Surface Vessel (USV) or unmanned ship uses Long Range (LoRa) technology. LoRa was chosen because of its ability to transmit data over long distances with low power consumption, making it very suitable for applications in the maritime environment. The control system on the USV is responsible for controlling movement, so it involves several technologies and components that work together to ensure the USV can operate efficiently. The way a USV works involves several systems working together to allow the autonomous vehicle to operate on the water surface unmanned or without direct human intervention. Under Line of Sight (LOS) conditions, the range of LoRa-02 to control unmanned is success rate up to a distance of 100 meters and achieved a 100% for data transmission. However, in the Non-Line of Sight (NLOS) test, there was a decrease in the range of only 70 meters due to obstacles such as trees or other objects. The transmitted data comes from the wireless camera in the form of images with timestamp displayed in real-time. The display from the wireless camera is utilized for visual field monitoring and can be monitored remotely.

In this modern era, people have various activities and to fulfill these activities, people need transportation as a supporting tool/assistant tool in carrying out their activities. Therefore, transportation service entrepreneurs are competing to attract the interest of their consumers by improving services, ease of ordering, fleet comfort, punctuality and so on. In Indonesia, there are many types of transportation that also function as public transportation, namely transporting people/goods and collecting agreed fees. The general public is currently familiar with two types of transportation, namely application-based online transportation and conventional transportation. Where application-based online transportation is the transfer of goods and people from place of origin to destination. The current flow of technological developments is something that must be understood and whether we like it or not, we must keep up with the flow of technological developments, so that the emergence of application-based online transportation is a transportation service that takes advantage of technological developments. Conventional transportation is passenger transportation carried out on a rental basis. Conventional transportation, for example, includes buses, public transportation, taxis, pedicabs and motorbike taxis. In line with current developments, the existence of conventional transportation is gradually being replaced by the choice of more sophisticated modes of transportation with the use of technological advances such as the emergence of application-based online transportation. Apart from being time efficient, online transportation itself can also be used at an affordable cost. However, this is different with conventional types of transportation, not all of which can be reached easily, sometimes you have to wait for a long time to be able to access or use these transportation services. Using Comparative Analysis The use of Comparative Analysis aims to compare the differences in services between two types of online and conventional transportation modes based on the type of transportation mode and the services provided by service providers to users such as the Academic Community located on the Cenderawasih University campus environment. By using Descriptive Statistical Analysis the data that has been collected can be analyzed by calculating the average perception of user respondents regarding service quality preferences for two types of online and conventional transportation modes from the Academic Community in the Cenderawasih University Campus environment.

This study examines the influence of the school environment on students' speaking ethics at SMA Negeri 1 Gedeg Mojokerto, considering the importance of character education in schools as a place where students spend much of their time. Using a correlational method and quantitative research type, the researcher involved 193 eleventh-grade students from a population of 425 as respondents. Data collection was carried out through a questionnaire with 38 statements that had been tested for validity and reliability. Data analysis included descriptive analysis, normality test, linearity test, as well as correlation coefficient analysis, determination coefficient analysis, and simple regression analysis for hypothesis testing. The results showed that the school environment and students' speaking ethics were in the moderate category, with average scores of 65 and 73, respectively. There is a significant influence of the school environment on students' speaking ethics, as evidenced by the t-test result (8.364) being greater than the t-table (1.97), leading to the acceptance of Ha and the rejection of Ho. Simple linear regression analysis showed a regression coefficient of 29.881, with an R square of 0.268, indicating that the school environment positively affects speaking ethics by 26.8%, while 73.2% is influenced by other factors. This study supports the theory that the school environment influences students' speaking ethics.

Internet financial reporting is crucial to raising public confidence and is one of the ways to maintain clean and good governance. The government has issued regulations on Internet Financial Reporting but has not been fully implemented by the district/city and province governments. Earlier studies indicated that local real income (PAD), government size, and regional spending influenced the implementation of Internet Financial Reporting but the results were inconsistent. The study aims to find out the impact between PAD, government size, and regional spending on the implementation of Internet Financial Reporting. The samples in this study consisted of 33 data obtained using purposive sampling techniques from 38 provinces, with observation time ranges from 2020 – 2022. The analysis of this study uses a double linear regression method using SPSS 22 software. Research results show that PADs and government measurements influence Internet Financial Reporting, but regional spending has no influence over the implementation of Internet financial reporting by the provincial government in Indonesia.
