The issue of illegal parking in Batam City has become a serious concern, where unofficial parking attendants often collect fees from drivers without contributing to the local government. This situation not only disrupts order and security but also harms local revenue (PAD). Illegal parking practices create discomfort for the public and reduce trust in the existing parking system. Moreover, it hinders the optimization of PAD potential that should be generated from a well-organized and orderly parking system. This research aims to develop a technological solution to address this issue by creating an Android application called Fast Parking System. The application is designed to improve parking system efficiency through a fast, secure, and transparent cashless payment system. By using this application, drivers can pay for parking digitally, reducing direct interaction with parking attendants and minimizing the potential for illegal fees. The application is also integrated with an official surveillance system, allowing local authorities to monitor parking activities in real-time and ensure that parking fees are directed to the local treasury. It is expected that the implementation of Fast Parking System will create a more orderly, safe, and efficient parking system. With this solution, the local government can not only increase transparency but also optimize revenue from the parking sector. In addition, the application offers greater convenience for the public in using well-managed parking facilities. The findings from this research can serve as a useful reference for the Batam City Government and other cities in Indonesia facing similar illegal parking issues. It can also be used as a guideline for developing more efficient and modern technology-based parking systems.

One emerging innovation is the electric motor-based turbojet fan, which is expected to replace conventional fossil-fueled systems. As the need for energy efficiency increases, studies on electrical power consumption and airflow performance are crucial in supporting the development of new-generation propulsion systems. This study aims to evaluate the relationship between nozzle angle and the characteristics of electrical power consumption and airflow velocity in a double-spool turbojet fan. The method used is an experimental test with an ESP32-based control system. The duty cycle is set at 80% to maintain operational stability. Research data is obtained through measurements of electrical current, voltage, and airflow velocity. The nozzle angle variations tested include 13°, 19°, and 25°. The test results show a significant difference between nozzle angle variations on electrical power consumption and wind speed performance. The 13° nozzle angle produces the highest electrical power consumption, indicating a greater energy requirement to maintain airflow. Conversely, the optimal wind speed was found at an angle of 19°, indicating a balance between energy efficiency and aerodynamic performance. Meanwhile, an angle of 25° showed a decrease in performance in terms of both power and speed, making it less effective. In conclusion, the nozzle configuration has a direct influence on energy consumption and fluid dynamics in electric turbojet fan systems. This research provides an important contribution to the design of electric-based propulsion systems by emphasizing efficiency and performance aspects, while supporting the transition to environmentally friendly technologies.

Madrasas and Islamic boarding schools are Islamic educational institutions that have a strategic role in shaping the character, morals, and competencies of students. In addition to carrying out the formal learning process, these two institutions are also centers for moral, spiritual, and social development. In their operations, madrasas and pesantren manage various administrative activities, such as student data collection, attendance recording, grade processing, teacher data management, lesson schedule preparation, and delivery of academic information to related parties. However, many institutions still use manual systems that rely on notebooks or separate applications that are not integrated. This condition poses a number of obstacles, including the high risk of recording errors, duplicate data that is difficult to track, the slow process of recapitulation of grades and attendance, and delays in the delivery of academic information. In addition, manual processes cause administrative management to be less efficient and prone to data loss. As the need for fast, accurate, and accurate information increases, technological solutions are needed that are able to integrate all administrative and academic processes in one centralized system. Web-based information systems are an effective alternative to improve work efficiency, minimize errors, and facilitate access to information for teachers, students, and guardians. With the implementation of a well-managed system, madrasas and Islamic boarding schools are expected to improve the quality of services and support a more modern, structured, and sustainable learning process.

This study aimed to evaluate the effect of compost fertilizer and potassium chloride (KCl) fertilizer, as well as their interaction, on the growth and yield of sweet corn (Zea mays saccharata Sturt). The experiment was conducted from May to August 2022 in Kuning Village, Bambel District, Southeast Aceh, using a factorial randomized block design with two factors: compost dosage (480 g/plot, 960 g/plot, 1,440 g/plot) and KCl dosage (20 g/plot, 40 g/plot, 60 g/plot), each replicated three times for a total of 27 plots. Observed parameters included plant height, stem diameter, leaf area, days to flowering, ear length, and ear weight per plot. Results indicated that compost and KCl fertilizers significantly affected plant height, leaf area, days to flowering, and ear length, but had no significant effect on stem diameter or ear weight per plot. The interaction between compost and KCl produced the highest plant height (165.89 cm) and ear length (21.69 cm) in treatment K3C1. The findings suggest that optimal fertilization using compost and KCl can enhance sweet corn productivity by improving vegetative growth and reproductive development. Nevertheless, the absence of significant effects on stem diameter and ear weight per plot indicates that nutrient balance, especially nitrogen (N) and phosphorus (P), remains crucial for maximizing yields. Therefore, integrating compost and KCl with complementary sources of macronutrients could promote more consistent outcomes. This research also highlights the role of organic matter in enriching soil fertility, maintaining soil structure, and supporting sustainable agriculture. The combination of organic and inorganic fertilizers demonstrates the potential for eco-friendly crop management practices that balance productivity with environmental responsibility. These results provide valuable insights for farmers, agronomists, and policymakers in developing efficient fertilization strategies for sweet corn cultivation within local conditions.
