Laundry services are one of the service businesses that have good prospects today. Because city people are getting busier, making laundry service businesses increasingly in demand and competition for similar service provider companies is getting tighter so that companies must improve service quality so that consumers continue to subscribe to using these laundry services. However, we find that many MSME players still have not or do not record financial reports so that these MSME players have difficulty knowing the details of their business activities so far, whether they are making a profit or even experiencing a loss. Therefore, the researcher here helps the owner to record financial reports so that in the future the owner can find out the profit and how to make this laundry service business grow. The research method used in this case uses the Descriptive method, where researchers go directly to the field to conduct observations and interviews with the owner of Mommy's laundry. In this study, researchers have assisted laundry service business owners in recording financial reports that occur, so that in the future it is hoped that laundry owners can make their own records for the development and sustainability of the business.

Growth and development disorders are a problem that is often found in society, so it is very important that all components involved in children's growth and development, namely parents, teachers and the community, can work together in early monitoring. The determining factors for the quality of a child's growth and development are constitutional genetic-heredo potential (intrinsic) and the role of the environment (extrinsic). Child growth and development disorders occur when there are genetic factors and/or environmental factors that are unable to meet the child's basic growth and development needs. Factors that influence a child's growth and development are genetic factors, and are more influenced by environmental factors and the diseases experienced by the child. Appropriate detection and intervention can optimize the quality of the child's subsequent growth and development. Babies who experience delays in development will make the baby's parents feel anxious and worried, which will affect how parents meet their baby's needs, such as mothers who do not encourage their babies to talk and mothers who do not exercise their hands and feet regularly at certain times. So that the baby has difficulty walking and lacks language, the lack of stimulation given to the baby will worsen the baby's developmental delays (Hurlock, 2002).Based on a preliminary survey conducted at the BP Nauli Community Health Center on 10 mothers who had babies, there were 5 mothers who did not provide stimulation to their children when their children were not going through the crawling phase and did not know the effect on the child's development, so based on these problems the researchers wanted to conduct research with the title "The Effect of Assisted Crawling Stimulation on the Crawling Ability of Babies at the BP Nauli Community Health Center, Kec. Siantar Let's See Pematang Siantar City in 2023   .

This study aims to determine the effect of perceived convenience, publication, convenience of access and trust partially on purchase intention. The population in this study were users of the KAI Access mobile application and the sample for this study was 100 respondents. The sampling technique is nonprobability sampling with the type of sampling that is purposive sampling. Data analysis used in this study was descriptive analysis and quantitative analysis, data were analyzed using multiple linear regression analysis with the help of (software) Statistical Package for Social Science (SPSS) version 26. The results of research by testing the hypothesis t-test showed that perceived ease of use, publication, ease of access and trust have a positive and significant effect on purchase intention. Based on the research results, it can be seen that the research model of the multiple linear regression equation is:Y= -1.735 + 0.291.X1 + 0.256.X2 + 0.247.X3 + 0.335.X4 + μ The results of the equation show that the Perceived Convenience variable (X1) has (t count 3.442 > t table 1.984), the Publication variable (X2) has (t count 2.398 > t table 1.984), the Ease of Access variable (X3) has (t count 2.892 > t table 1.985) and the variable Trust (X4) has (t count 4.802 > t table 1.984). As for the value of Adjusted R2 = 0.619. This means that 61.9% of the variation in the dependent variable (Y), namely Purchase Intention, is explained by the independent variables, namely Perceived Convenience, Publication, Convenience of Access and Trust. The remaining 100% - 61.9% = 38.1%, other variables not proposed in this study.

Quantum computing has emerged as a revolutionary paradigm, holding immense potential to solve complex problems that classical computing struggles to address. This study explores the application of quantum computing in cryptography, with a specific focus on two major quantum algorithms: Shor’s algorithm for large number factorization and Grover’s algorithm for unstructured database searching. The main objective of this research is to compare the performance of these quantum algorithms with classical cryptographic methods in terms of computational efficiency and time. Shor’s algorithm, which can factorize large numbers in polynomial time, presents a significant threat to the security of public-key cryptosystems such as RSA, which rely on the difficulty of factoring large numbers. On the other hand, Grover’s algorithm offers a quadratic speedup for searching unstructured databases, making it highly relevant for symmetric key cryptography systems like AES. In this study, simulations of both algorithms were conducted using quantum simulators to assess their speed and effectiveness in solving cryptographic challenges. The results demonstrate that quantum algorithms significantly reduce the computation time compared to classical methods, with Shor’s algorithm efficiently solving factorization problems and Grover’s algorithm accelerating key searching processes. However, while these quantum algorithms show promise in improving cryptographic systems, the implementation of large-scale quantum computers remains a challenge. This research highlights the potential of quantum computing to revolutionize data security and underscores the need for further development in quantum algorithms and the transition to quantum-resistant cryptographic systems to safeguard against the threat posed by quantum computers.

Education is a process needed to obtain balance and perfection in the development of individuals and society. Education itself is faced with various problems that become obstacles to the quality of education itself. This can be seen in various aspects, some of which include the lack of adequate physical facilities such as the feasibility of buildings used in the learning process. These problems can hinder the development of students to reach their best potential and cause inequality in terms of access to quality education. There are differences in the quality of education in rural and urban areas, where rural areas have more specific challenges such as lack of school facilities, difficulty of access, and technological and social changes. In the context of education, technology has changed the way we learn, access information and communicate. Social changes, such as changing demographics, can also affect the way we design education systems. These factors create pressures on education that require creative thinking and innovative solutions. This research uses qualitative research methods through a phenomenological approach. The theoretical foundation used in this research is the functional structural theory proposed by Talcott Parson. Data collection in this study used interviews, observation, and documentation.  

One of the media used by PAI teachers at SDN Pakan Labuh 03 is Student Worksheets (LKPD) in learning, especially in Islamic Religious Education lessons. The teacher only gives an explanation of the material then practices the prayer movement directly, then evaluates it.
