Photosynthesis is a vital process for plants in converting light energy into chemical energy stored in organic compounds. Light intensity is one of the main factors influencing the efficiency of this process. This study aims to determine the effect of different light intensities on the photosynthesis rate and growth of spinach plants (Amaranthus sp.), which is a C4 plant species.The method used was a quantitative experiment with three light intensity treatments: low (0–10 lux), medium (10–20 lux), and high (>20 lux), each replicated three times over six weeks. Observed parameters included plant height, number and length of leaves, as well as the photosynthesis rate measured using the IRGA method.The results showed that light intensity significantly affected the growth and photosynthesis rate of spinach plants. The high light treatment produced the most optimal growth, with an average plant height of 4.92 ± 0.4 cm and the highest photosynthetic activity. Conversely, the low light treatment caused symptoms of etiolation, reduced vitality, and faster plant death, averaging by the third week.In conclusion, increasing light intensity significantly enhances photosynthesis efficiency and growth in spinach plants. These results can serve as a basis for regulating light intensity in cultivation systems, both conventional and hydroponic.

This study discusses the arrangement of queue lanes in the supervision of weighing freight transportation at UPPKB Singosari to improve service efficiency. Based on the analysis of the Minimum Service Standards (SPM), three main indicators, namely compliance, conformity, and implementation, have reached 100%, while the accuracy indicator has only reached 50% due to the duration of weighing exceeding the set time limit. The main factor causing long queues is the lack of clear lane markings, making it difficult for vehicles to be directed without an officer. In addition, the parking area of 3,330.6 m² has not been utilized optimally. Improvement efforts include the implementation of queue lane markings to reduce dependence on officers, optimization of facilities such as Pos 2 which is parallel to Pos 1, and improvement of human resource management to suit operational needs. The use of Weight in Motion (WIM) technology is also recommended to reduce workload and accelerate the supervision of freight transport vehicles. By implementing this strategy, it is hoped that services at UPPKB Singosari can be more efficient, transparent, and in accordance with applicable standards.

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.
