Public Street Lighting (PJU) plays an important role in transportation infrastructure, especially at night. Currently, complaints about PJU damage are only made using social media. This research designs and builds a web-based PJU complaint system with real-time notifications via WhatsApp in Pemalang Regency. Data was collected through interviews, observations, and questionnaires. This system is built with PHP and MySQL, with WhatsApp notification integration to ensure accurate and real-time complaint information. The system trial involved the community, showing the system's effectiveness in increasing reporting efficiency and officer response. The system provides easy online reporting and real-time notifications via the website and WhatsApp. This system is expected to improve community services and PJU management. The results can be a reference for the development of similar systems in other areas.

Purpose: This work aims to apply Quantum Hilbert Scrambling to enhance the security and integrity of image watermarking without affecting visual quality degradation. Further conception of the surveyed methods could result in a very good solution to conventional methods of watermarking in solving some problems of digital image security and integrity with new concepts of quantum computing.
Methods: The paper reviews Quantum Hilbert Scrambling, whose computational complexity is . The process involves encoding the image into a quantum state, permuting qubits by the Hilbert curve, and embedding a watermark using quantum gates.
Result: The quantitative performance evaluation metrics, like Peak Signal to Noise Ratio (PSNR) and Structural Similarity Index (SSIM), have shown high Peak Signal to Noise Ratio (PSNR) values from 56.13 dB to 57.87 dB and Structural Similarity Index (SSIM) from 0.9985 to 0.9990, correspondingly. This justifies the fact that the quality degradation is very slight and the fine details of the structure are well maintained.
Novelty: The proposed method uniquely integrates quantum computing with traditional watermarking steps for a secure and effective approach in digital watermarking. Further development should focus on improving the quantum circuit regarding computation efficiency, extending the applicability of the method to a wide range of images, and various situations in watermarking, and finding hybrid approaches by combining quantum and classical approaches towards better performance and scalability.

This study focus on identifying medical images by proposing the Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) transformation watermarking technique and prove an increase the quality of watermarked images is good in terms of imperceptibility. Due to reduce the need for data memory compression is applied to the host image, where the compression technique chosen is lossless so that the compressed host image experiences a decrease in file size while maintaining data integrity, to maintain image degradation perceptions and diagnostic quality standards during the watermarking process. Here, we use DWT-DCT-SVD and Run Length Encoding (RLE). A good Peak Signal to Noise Ratio (PSNR) more than 30 dB using over than 200 compression size. The extracted watermark image is quite good with a fairly high PSNR value. The highest compression result size is in 32.2511.

The purpose of the service is to socialize the use of the mind-mapping learning model in social studies learning content. Method of implementation with lectures and discussions. Stages of implementation: preparation, implementation, and evaluation. Equipment: laptop, LCD projector, and consumption. Participants: school principals and teachers. Implementation results: the implementation of the socialization was successful through the provision of material on the use of mind mapping models and procedures for using mind mapping models. Implementation of socialization can provide a choice of solutions to solve problems in learning activities by applying the mind-mapping learning model. Socialization activities can facilitate increasing understanding of the use of learning models by educators of the Technical Implementation Unit of the Gili Anyar Bangkalan Public Elementary School Service.

Thematic learning becomes very important in the era of the 2013 curriculum and also the current independent learning curriculum, the output of the two curricula is strengthening the processes and learning outcomes for students. The seminar was conducted with the aim of strengthening and increasing the teacher's pegagogical competence, especially in terms of learning innovation. The seminar was conducted offline with a duration of 200 minutes on August 29 2022 at UPTD SDN Pangilen 3 Sampang which was attended by 8 teachers. The speaker uses the help of a laptop as a medium for delivering material. The results of the seminar implementation: 1) The first speaker gave material about holistic and meaningful learning, the second speaker gave authentic and active learning material. 2) The seminar runs actively as evidenced by lively discussions. 3) The results of the teacher's seminar increasingly understand and can practice holistic, meaningful, authentic and active learning in front of the presenters. The impact of this seminar is as a reference material and study for other schools, especially rural schools that have not implemented thematic learning as a whole.

The purpose of this study was to determine the effect of plastic cups & marbles props on the level of understanding, activity and understanding and activities of students in learning mathematics. This study uses a quantitative research method with a Quasi Experimental Design research design. The population in this study were all students of SD Negeri Mlajah 2 Bangkalan as many as 454 students, the samples were class IIa and class IIb, the determination of the sample was carried out using purposive sampling. The results showed that 1) there was an effect of plastic cups & marbles props on the level of students' understanding of mathematics learning and obtained a sig value. of 0.012 < 0.05 for class A and 0.004 < 0.05 for class B. 2) There is an effect of teaching aids plastic cups & marbles on student activities in class A mathematics learning with a value of sig. of 0.000 < 0.05. 3) there is no effect of plastic cups & marbles props on student activities in class B mathematics learning with a sig. of 0.986 > 0.05 in accordance with the criteria for the Multivariate Analysis of Variance test.
