In the era of maritime technology, Unmanned Surface Vehicles (USVs) are becoming the main vehicles on the water surface, controlled from land and capable of transmitting live data. USVs have a wide range of survey and exploration applications, relying on hydrographic knowledge for accurate mapping. USV development has adopted a double hull design, improving stability and wave resistance. Survey data transmission requires advanced technology, with Long Range (LoRa) technology being the solution for long distance data transmission with low power consumption. LoRa utilisation is expected to increase the efficiency of USVs in hydrographic surveys. The research and development (R&D) research method is used as the main approach in this research with the aim of creating and developing USVs that can increase efficiency in hydrographic surveys. The USV is equipped with an RPM sensor and flowmeter used to monitor the movement control of the USV in the waters. In addition, a depth detector is used to monitor the topography of the seabed. In order for this USV to run using a remote control that is controlled from land. The USV drive consists of a BLDC motor connected to the propeller and a servo motor connected to the ship's rudder. Furthermore, the data taken from the sensor is sent via LoRa to be delivered to the ground station. From the USV test results, it was found that the data transmission range with LoRa Ra-02 under Line of sight (LOS) conditions was 340 metres while under Non Light of sight (NLOS) conditions it was around 200 metres. The average speed travelled by USV is 0.616 km/hour in operational survey conditions and can be faster in non-operational survey conditions. The error value of the RPM sensor is obtained at 1.604% with a reading accuracy of 98.936%.

This study analyzes the influence of payment gateways, financial literacy, and digitalization on the financial performance of MSME actors in Brebes Regency, especially Mitra Mandiri MSMEs. MSMEs have a significant role in Indonesia's economy, but they still face various challenges, especially in the aspects of financial technology and digital literacy. Payment gateways enable faster and safer transactions, while financial literacy supports better cash flow management and financial planning. Digitalization also plays a role in improving operational efficiency. This study uses a quantitative method with a survey approach to 51 respondents. Data were collected through questionnaires and analyzed by multiple linear regression to test the relationship between variables. The results of the study show that payment gateways and financial literacy have a positive and significant effect on the financial performance of MSMEs. Payment gateways improve transaction efficiency and expand market access, while financial literacy helps in better financial management. However, digitalization does not have a significant influence on financial performance, showing that the implementation of digital technology still faces obstacles in the adoption and optimal utilization by MSME actors. These findings emphasize the importance of increasing the use of payment gateways and financial literacy education for MSME actors to improve their financial performance.

This research aims to analyze the use of Internet of Things (IoT) technology in the marketing strategy of the oil and gas industry in Indonesia, with a focus on aspects of compliance with applicable oil and gas laws and regulations. The use of IoT technology has brought significant changes in various industries, and the oil and gas sector is no exception. In this context, this research will investigate how IoT technology can be used in oil and gas marketing strategies to improve operational efficiency, supervision, and compliance with oil and gas law regulations in Indonesia. The importance of compliance with oil and gas law regulations cannot be separated from the broader legal framework, namely the 1945 Constitution of the Republic of Indonesia (UUD 1945). The 1945 a Constitution is the Indonesian constitution which establishes the basic principles of the state, including the management of natural resources, including oil and gas, which are in the national interest. In this research, the use of IoT technology in oil and gas marketing strategies will be analyzed by considering the perspective of compliance with applicable oil and gas law regulations, which are part of the legal framework regulated by the 1945 Constitution and support state sovereignty in managing natural resources. Through literature analysis and case studies of the oil and gas industry in Indonesia, this research aims to provide a deeper understanding of the potential use of IoT technology in the oil and gas industry in Indonesia and its implications for compliance with oil and gas law regulations. It is hoped that the results of this research will provide valuable information for oil and gas companies, regulators, and other stakeholders in formulating effective marketing strategies and complying with applicable regulations. In addition, this research also has the potential to become the basis for further research in this field. By understanding and applying IoT concepts in oil and gas marketing strategies that comply with oil and gas law regulations and the principles set out in the 1945 Constitution, a more efficient, controlled, and sustainable oil and gas industry can be created in Indonesia.
