Natural insecticides are pest control materials derived from natural sources such as plants. The use of natural insecticides is very important because it has a lower cost, is safe for living things and does not pollute the environment, so this study aims to determine the activity of essential oils and n-hexane extracts of beluntas leaves (Pluchea indica L.) as natural insecticides with bioindicators of Hong Kong caterpillars (Tenebrio molitor). Isolation of essential oils was carried out using the steam distillation method and extraction using the maceration method. Insecticide activity tests used the contact poison method and the residue method, with variations in extract and essential oil concentrations of 1%, 3%, 5%, 7%, 10%, 20%, 30% (v/v) and positive controls, namely Hippo insecticide and negative control tween 80. The results of the isolation of essential oils from beluntas leaves produced a yield of 2%, while extraction using the maceration method produced a yield of 1.84%. The results of the insecticide activity test using the contact poison method were more effective than the residue method. The insecticidal activity and n-hexane extract are more effective than essential oils, this is due to the differences in the content of secondary metabolite compounds contained in the extract and essential oil.

Complete basic immunisation is a key public health intervention to prevent infectious diseases in infants. However, immunisation coverage remains suboptimal, particularly due to limited maternal knowledge and negative perceptions. This study aimed to assess the effect of health education on mothers’ attitudes toward complete basic immunisation in Tembung Village, Deli Serdang Regency. A pre-experimental one-group pretest–posttest design was employed, involving 20 mothers with infants, purposively selected from three hamlets with low immunisation coverage. The intervention consisted of interactive health education addressing the benefits, schedule, and common post-immunisation reactions. Maternal attitudes were measured using structured questionnaires before and after the intervention and analysed descriptively. The results demonstrated an improvement in positive attitudes across all indicators following education, including acceptance of immunisation despite concerns about side effects and access barriers. These findings indicate that community-based health education effectively enhances maternal acceptance of immunisation. Nevertheless, short-term evaluation may be subject to social desirability bias, underscoring the need for sustained, repeated educational interventions.

Nucleic acids are extremely important biomolecules. Their function is to store, regulate, and pass on genetic information in living organisms. There are two main types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which are composed of small units called nucleotides. This study aims to explain the structure and function of DNA and RNA, as well as to distinguish their characteristics. Additionally, this study analyzes the relationship between gene mutations and the formation of cancer cells. The method used is a literature review employing a qualitative descriptive approach, conducted by examining various scientific journals from both domestic and international sources. The results of the study indicate that DNA has a double-helix structure that functions to store genetic information stably, while RNA is typically a single strand that plays a role in protein synthesis. Genetic changes caused by DNA damage can alter the sequence of nitrogenous bases, which has the potential to lead to the growth of cancer cells. Analysis using graph decomposition indicates that deletion and insertion mutations have a greater impact on genetic structural changes compared to substitution mutations. Additionally, natural substances rich in antioxidants, such as turmeric, green tea, garlic, and soursop leaves, can help prevent DNA damage. Thus, understanding the structure of nucleic acids and gene mutations is crucial for the advancement of genetics, molecular biology, and health technology.

Daun sukun (Artocarpus atilis) merupakan bagian dari tanaman yang kaya akan senyawa aktif yang berfungsi sebagai sumber antioksidan. Dalam pembelajaran biokimia daun sukun juga dikenal memiliki sifat antibakteri, anti-inflamasi, dan potensi dalam melawan kanker. Penelitian ini bertujuan untuk mengeksplorasi potensi aktivitas antioksidan dari ekstrak etanol daun sukun baik yang muda maupun yang tua. Proses ekstraksi dilakukan dengan cara maserasi terhadap serbuk simplisia daun sukun muda dan tua menggunakan etanol 96%. Ekstrak etanol tersebut diberi konsentrasi yang berbeda, yaitu 5, 10, 20, dan 40 μg/ml untuk daun sukun muda dan tua, sementara vitamin C digunakan konsentrasi 0,5, 1, 2, dan 4 μg/ml sebagai perbanding. Metode yang diterapkan dalam penelitian ini adalah metode DPPH (2,2-diphenyl-1-picrylhydrazyl). Hasil dari penelitian menunjukkan bahwa daun sukun muda memiliki nilai IC 50 yang lebih rendah dibandingkan dengan daun sukun tua, yaitu sebesar 32,20 μg/ml daun sukun muda dan 49,56 μg/ml daun sukun tua, sementara vitamin C memiliki nilai IC 50 sebesar 11,51 μg/ml. Berdasarkan nilai IC 50 tersebut, daun sukun muda dan tua memiliki katagori yang sama sebagai antioksidan (sangat kuat).Dari segi aktivitas antioksidan daun sukun muda memiliki potensi aktivitas yang lebih baik dibandingkan daun sukun tua dalam penggunaan sebagai sumber antioksidan alami.

The Effect of STEM Worksheet-Assisted Project-Based Learning on Learning Outcomes and Interest in Acid-Base Topics This study aims to analyze the effect of implementing a Project-Based Learning (PjBL) model supported by STEM worksheets on students’ learning outcomes and interest in acid-base concepts. The study employed a quasi-experimental method using a pretest-posttest control group design. The sample consisted of two 11th-grade classes at State High School 4 Medan, which served as the experimental and control groups, respectively. The research instruments consisted of a learning outcome test comprising 20 multiple-choice questions that met the criteria for validity and reliability, as well as a learning interest questionnaire consisting of 25 statements. The data were analyzed using the N-Gain test, normality test, homogeneity test, independent samples t-test, and Pearson’s correlation test. The results showed that the average posttest score for the experimental class was 87.22, which was higher than that of the control class at 75.97. The N-Gain score for learning outcomes was 0.77 (high category) for the experimental class and 0.57 (moderate category) for the control class. Regarding learning interest, the N-Gain was 0.70 (high category) in the experimental class and 0.50 (moderate category) in the control class. The results of the independent samples t-test showed a p-value < 0.001, leading to the conclusion that the Project-Based Learning model supported by STEM worksheets has a significant effect on students’ learning outcomes and learning interest in acid-base material.

Sleep deprivation is an increasingly common problem due to changes in modern lifestyles and can have negative impacts on health. One of the most significant biological consequences is the increase in oxidative stress, which may lead to DNA damage and impaired cellular function. This study aims to examine the effects of sleep deprivation on DNA damage and cellular health based on findings from various published studies. The method used was a qualitative literature review. Data were collected from national and international scientific articles discussing the relationship between sleep deprivation, oxidative stress, DNA damage, and cellular health. The collected data were analyzed descriptively to identify the relationships among these variables. The review findings indicate that sleep deprivation increases the production of Reactive Oxygen Species (ROS), which triggers oxidative stress and causes DNA damage. Furthermore, sleep deprivation may inhibit DNA repair mechanisms, alter gene regulation, and increase the accumulation of genetic damage within cells. Persistent DNA damage can induce cellular aging, apoptosis, and increase the risk of various chronic diseases. Therefore, adequate sleep quality and duration are essential for maintaining DNA stability and cellular health.
