The influence of the development of Science and Technology (IPTEK) on the world of education, so that both teachers and students are required to always adapt to existing developments. Technology is the result of knowledge originating from the world of education therefore the world of education should utilize technology to increase efficiency in learning. Chemistry among students is still considered material that is difficult to understand. One of its attractions is the abstract nature of chemical material. Chemistry learning does not only include theoretical learning but also includes practical activities. This research was carried out to determine the effect of using a virtual laboratory on students' skills during direct practicum. The method used in this research is a quantitative method that uses a lot of numbers, starting from data collection, interpretation of the data and presentation of the results. A total of 52 students in class XI, Department of Mathematics and Natural Sciences at SMA Negeri 1 Sliyeg. Presenting the results in the form of a representative table will increase the reader's level of understanding and make it easier to access information. Virtual laboratories help students understand the practical process. Based on the results of data analysis obtained from filling out the questionnaire, it was found that 78.8% or the majority of students answered agreeing that the virtual laboratory had an effect on increasing pH testing. This proves that the use of virtual laboratories can be a way out so that when doing direct practicum students do not experience difficulties and the practicum runs more effectively.

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.

Latar Belakang: Lymph node cancer in the case of Hodkin's Lymphoma is a type of cancer. Lymphoma is a solid tumor of the immune system. Hodgkin lymphoma (HL) accounts for about 10% of all lymphomas. The Intensity Modulated Radiation Therapy (IMRT) technique is one of the cancer treatment techniques in Hodgkin's Lymphoma cases. The aim of this research is to determine the procedure and reasons for using the IMRT technique in lymph node cancer in Hodkin's Lymphoma cases.Metode: This research is qualitative research with a case study approach using retrospective data. The research time is from 24 to 30 May 2023 and the research location is in the Department of Radiation Oncology, RSUP Dr. Hasan Sadikin Bandung. The research subjects consisted of Radiation Oncologists, Medical Physics, Radiotherapists. Researchers collected data from patient medical records, made interview transcripts and carried out data reduction and processed it using open coding, and provided it in the form of quotations and then drew conclusions.Hasil: The procedure for irradiating Hodgkin's Lymphoma using the IMRT technique at the RSHS Department of Radiation Oncology begins with positioning the patient on the examination table with a fixation device and arranging the patient according to the reference point of the CT Simulator and making a thermoplastic mask then carrying out verification and irradiation. The IMRT technique has the advantage of using MLC so that the radiation is modulated according to the contour of the target and the disadvantage of precise dose distribution in limiting the radiation dose to organs at risk.Kesimpulan: In the case of the Department of Radiation Oncology, Dr. Hasan Sadikin Hospital, Bandung, the IMRT technique was used with consideration, namely that the IMRT technique already uses MLC which creates individual blocks automatically according to the projections depicted on the TPS.  

The 3DCRT field in field (FIF) technique used in Post MRM breast cancer patients at the Radiotherapy Unit at Lavalette Hospital Malang uses 4 copy fields including supraclavicular (AP), axilla (PA), tangential (ML/LM). However, in the Radiotherapy Unit at Lavalette Hospital, Malang, the immobilization device does not use a breast board but uses an abdominal thorax or AIO Breast And Lung Board. The aim of this study is to describe the management or procedures for administering 3DCRT field in field (FIF) radiotherapy with abdominal thorax immobilization in Post MRM breast cancer patients at the Radiotherapy Unit at Lavalette Hospital, Malang. Treatment of 3DCRT field in field (FIF) radiotherapy with abdominal thorax immobilization in Post MRM breast cancer patients at the Radiotherapy Unit at Lavalette Hospital Malang consists of an examination and consultation with a radiation oncology specialist, CT Simulator, then treatment planning system (TPS), verification carried out before the first fraction and participation stage. The advantage of using the 3DCRT field in field (FIF) technique with abdominal thorax immobilization in Post MRM breast cancer patients at the Radiotherapy Unit at Lavalette Hospital, Malang, is that the copying area is simple, the copying comfort is better, it can reduce hotspots, and it can reduce the dose received by the organs in the area. risk (OAR). The disadvantage is that it requires more precision, especially RTT as an operator for the use of additional immobilization devices other than the 5 degree abdominal thorax.
