Thalassemia is an inherited hemolytic anemia caused by genetic abnormalities in chromosomes 11 and 16 that impair globin chain production, leading to insufficient hemoglobin and red blood cells. This study aims to describe nursing care for An. W with thalassemia at the Anggrek 2 Ward of RSUD dr. Soeselo, Tegal Regency. The method used was a descriptive approach through anamnesis, documentation, observation, and literature review. Nursing care was carried out over two days (January 13–14, 2026). Physical examination results on January 12, 2026 showed a pale face, anemic conjunctiva, weakness, CRT >3 seconds, decreased skin turgor, weak peripheral pulse, cold extremities, and laboratory hemoglobin of 5.9 g/dL, with vital signs of pulse 111x/minute, temperature 36.7°C, and respiration 22x/minute. Two nursing diagnoses were established: ineffective peripheral perfusion related to decreased hemoglobin concentration (D.0009), and activity intolerance related to weakness (D.0056). Nursing interventions included circulatory care (I.02079) and energy management (I.05178). Nursing implementation was carried out according to plan. Evaluation on January 14, 2026 showed that both nursing diagnoses were resolved; the patient's hemoglobin improved to 10.7 g/dL after two blood transfusions, and the patient was declared fit for discharge. It is recommended that hospitals establish support groups for thalassemia patients to provide adequate emotional and social support.

This study aims to observe the phases of mitosis in the meristem cells of shallot roots (Allium cepa) through microscopic observation as part of the Cell Biology learning model. Mitosis is an important part of the cell cycle that plays a role in growth, tissue repair, and asexual reproduction in organisms. A deep understanding of the mitosis process is an important foundation in various branches of biology, including genetics, biotechnology, and histology. Shallot roots were chosen because they have actively dividing meristem tissue at the root tip,as well as a large and transparent cell structure that facilitates the staining and observation process. Preparation was carried out by soaking the onion roots in a solution of acetic acid and alcohol for fixation,then staining with acetocarmine acid so that the chromosomes are clearly visible. The process of crushing the root tip and pressing it on a glass object (squash method) was used to expand the observation area. A light microscope with a magnification of 400x and 1000x was used to identify the division phases. Observation results show the presence of all phases of mitosis, namely prophase (nucleolus and nuclear membrane begin to disappear,chromosomes condense), metaphase (chromosomes line up at the equator), anaphase (chromatids separate to opposite poles), and telophase (nuclear membrane and two daughter cell nuclei re-form). Visual documentation in the form of microscopic photographs and descriptive tables clarify the identification of these phases, thus facilitating student understanding.From a pedagogical perspective, this microscopic practicum-based learning has been proven to improve students' observational skills, laboratory skills, and conceptual understanding of cell division. Students not only memorize theories, but directly experience the scientific process through exploration and discussion of observation results. Evaluation of learning outcomes is carried out through post-practicum quizzes and student worksheets, showing an increase in understanding scores of more than 30%.

Down Syndrome is a fairly common genetic disorder, this is one of the diseases caused by the emergence of an extra chromosome from 21 pairs of chromosomes or known as trisomy 21.

Data analysis is carried out through the stages of Data Reduction, Data Presentation, and Conclusion Drawing. The location of this study is at the Liliput Clinic, Jl. Cipete IV No. 06, Rt. 02 Rw 03, South Cipete, Cilandak District. The results of the study showed that the provision of Occupational Therapy for Down Syndrome Children, namely, Down syndrome children still tend to be limp, such as when doing activities they get tired more easily, then Down syndrome children have not been able to regulate their emotions stably. In improving fine motor skills in Down syndrome children, therapists train and instruct children how to hold objects properly such as pencils, pens and small scissors. Then the child is instructed how to write correctly. Supporting factors in Occupational Therapy for Down Syndrome Children are an experienced therapy background, supporting infrastructure, and support from parents of Down syndrome children. And the inhibiting factors are Down syndrome children who have high emotional levels and physical problems in Down syndrome children.

Down syndrome (DS) is a physical disorder caused by an excess of the third chromosome in the 21st pair of chromosomes which causes the number of chromosomes to become 47. One of the symptoms of Down syndrome is muscle weakness which can affect the baby's reflexes. To assess the effect of baby massage intervention on the reflex development of babies with Down syndrome in the NICU. The method used in this research is a case study with baby massage intervention for Down syndrome patients in the NICU. The intervention was carried out for 3 days. Baby massage intervention is carried out once a day with a duration of 10 -15 minutes. The results of this case study show that after baby massage there were changes in the palmar grasp reflex and Babinski reflex. Baby massage can improve babies’ reflexes particularly palmar and Babinski reflexes on babies with Down syndrome in the NICU.

Genetic algorithms are computer techniques inspired by the theory of evolution and genetics. Individual definition, chromosome initialization, chromosome testing, selection (crossover) and mutation are fundamental elements of genetic algorithms. Genetic algorithms are used to solve optimization problems, such as lesson planning, community services and traffic light adjustment. By producing the best combination of chromosomes, the genetic algorithm can achieve ideal results. The genetic algorithm produces appropriate planning data to avoid delays. This research uses the methods of data collection, individual definition and chromosome initialization. The result of this research is a service application designed to be able to plan efficiently through development using a genetic algorithm. Optimal planning occurs when processing planning data produces solutions that are efficient in terms of time, energy, and resources, and avoids conflicting schedules in the same place..

Virtual laboratories can provide real learning experiences through computer-aided simulations and activities. Virtual laboratory is rapidly developing its use in science learning because it is proven to provide significant benefits to the process and results of science learning during the pandemic. The limitations of laboratory facilities in genetics learning at the unkhair Biology Education Study program have encouraged the development of virtual practicum strategies and their use in genetic learning with modified free inquiry strategies on the topic of the structure and function of genetic material and reproduction of genetic material. The purpose of this study was to analyze the effectiveness of virtual laboratories based on student perceptions of the use of virtual laboratory applications and to describe and compare these perceptions with the use of laboratory reality and relevant previous research results. There are five aspects of perception surveyed, namely innovation, motivation, effectiveness, benefits, and presentation of practical procedures. This research method uses a quasi-experimental research design for the characteristics and effectiveness of using virtual laboratories and real laboratories in the Genetics course at the Biology Education Study Program, Khairun University, Ternate on the topic of DNA isolation, chromosomes and mitosis. The results of this study indicate that: the characteristics of Blended Learning practicum in the Genetics course in 4th semester students of Biology study program are: 1) instruction-based practicum; 2) practicum based on data collection and reporting of practicum results; 3) practicum based on proof of concept. The effectiveness of the implementation of genetics practicum in laboratory reality and virtual laboratories based on the perception of student responses is more likely to choose reality laboratories than virtual laboratories. The effectiveness of the implementation of genetic practicum based on the results of the practicum report is known to be not significantly different between the results of the practicum in reality and in the virtual laboratory.
