Abstract

The decline in land spinach (Ipomoea reptans Poir.) production is partly due to pest attacks, such as armyworms, aphids, and whiteflies. This study aims to determine the effect of a combination of basil (Ocimum basilicum) and bay leaf (Syzygium polyanthum) leaf extract as a botanical pesticide on pest attack intensity and to determine the most effective concentration. This study used a Randomized Block Design (RBD) with five treatments (0%, 30%, 40%, 50%, and 60%) and five replications. The analysis results showed that the combination of the two leaf extracts significantly reduced pest attack intensity. The 60% concentration resulted in the lowest attack intensity, at 18% (mild category), making it the most effective treatment. Thus, the combination of basil and bay leaf extracts has the potential to be an environmentally friendly botanical pesticide for pest control in land spinach.

Abstract

Medicinal plants have long been utilized by the traditional community in Darek Village to treat various illnesses. One of the plant parts most commonly used for medicinal purposes is the leaf. Leaves exhibit diverse characteristics in terms of shape and size across different species. Leaf morphology includes features such as shape, color, size, venation pattern, leaf margin, leaf apex, leaf base, surface texture, and others. This study aims to identify the plant species whose leaves are used in traditional medicine by the Darek community and to describe the morphological characteristics of these medicinal leaves. This research employed a eksplorative descriptive approach using semi-structured interviews to document local knowledge regarding the use of medicinal plant leaves in Darek Village. Respondents were selected through a purposive sampling technique, involving community leaders and individuals recognized for their traditional knowledge of medicinal plants. The collected data were analyzed through data reduction, classification, and conclusion drawing to identify the plant species used medicinally and their leaf morphological traits. The findings indicate that the community utilizes 15 types of leaves from 13 plant families as traditional medicinal resources. In general, these medicinal plants display diverse leaf morphological characteristics, particularly in surface texture, venation type, and the shapes of the leaf margin, apex, and base. This morphological variation reflects the diversity of species employed and serves as a basis for the community to recognize and differentiate medicinal leaves. These findings highlight the richness of local knowledge, which holds potential for further development in ethnobotanical studies and the conservation of biological resources.

Abstract

The development of digital technology in the world has increased the ease of access to education. However, it also creates new challenges that affect stress levels and academic achievement. This study focuses on analyzing the influence of digital mindfulness techniques on the level of stress experienced by students of the Department of Biology Education at Lambung Mangkurat University, as well as their academic achievements. A descriptive-exploratory method with a qualitative research approach was applied in this study. Data was collected through an online survey filled out by 71 students and 5 lecturers, as well as interviews with 9 students from various generations. Data analysis was carried out using a descriptive method, based on students' views and experiences. The results show that most students experience moderate to high levels of academic stress, especially due to multitasking on digital platforms and high academic expectations. Nonetheless, the application of digital awareness techniques contributes to more effective time management and improved ability to concentrate. This research highlights that digital awareness is essential to maintain a balance between technology use and students' mental health. Scientifically, the results of this study show the importance of digital awareness in biology education for adaptive, healthy, and sustainable learning.

Abstract

Cemara Labat Village is a coastal area located in Kapuas Regency, Central Kalimantan which directly faces the Java Sea and borders Pelampai Village, Batola Regency, South Kalimantan. The village receives enough sediment from the Kapuas River to support the development of mangrove forests. For generations, the people of Cemara Labat Village have managed coastal resources, namely mangrove forests based on traditional traditions known as local wisdom. Mangrove forest vegetation experiences significant dynamics that are very important for the survival of various fauna in it, such as mammals (langurs and proboscis monkeys), fish, shrimp, insects, and even various types of birds. The purpose of this study is to describe the existence of proboscis monkeys based on the population of dominant mangrove species. The research was carried out for six months, from January - June 2025. Data were collected using observation and survey methods. For mangrove observation, it is carried out by making three Observation Sample Plots (PCP) measuring 20 x 500 m, while for proboscis monkey observation by making six observation stations that are made intentionally. Proboscis monkey observation starts at 06.00-18.00 WIB. The results showed INP ≥ 10% of the 6 species found, such as the White Flame (Avicennia marina (Forssk.) Vierh.) 199.99% are included in the medium category (101-200%), Black Flame (Avicennia alba Blume.) is 42.36%, Jeruju (Acanthus ilicifolius L.) is 17.07%, Piai (Acrostichum aureum L.) is 13.39%, Blind (Excoecaria agallocha L.) is 6.70%, and Plepotan (Derris trifoliate) is 5.90% in the low category (0-100%). Eight proboscis monkeys (Nasalis larvatus) were found in the area of the observed object. Although Avicennia spp. dominates the vegetation, the population of proboscis monkeys is relatively small, suggesting that Avicennia spp. mangroves are not the main feed crops for proboscis monkeys and only serve as a migration area.

Abstract

HIV infection remains a global health challenge with high rates of new infections and low levels of viral suppression, especially in middle-income countries. Antiretroviral therapy (ART) has significantly reduced morbidity and mortality, but has not been able to eliminate latent reservoirs so lifelong therapy remains necessary. In the last decade, monoclonal antibodies, particularly broadly neutralizing antibodies (bNAbs), as well as CRISPR-Cas9 gene-editing technology have emerged as innovative therapeutic approaches with long-term remission potential. bNAbs is able to neutralize a broad spectrum of HIV strains and activate immune effector mechanisms, including antibody-dependent cellular cytotoxicity (ADCC) and phagocytosis, but cost limitations, viral resistance, and duration of effects limit its use as a substitute for ART. In parallel, CRISPR-Cas9 has demonstrated the ability to target HIV proviruses in the host cell genome and enable the engineering of immune cells to stably produce therapeutic antibodies. Pre-clinical studies show that B-cell engineering with CRISPR-Cas9 can maintain immune memory, perform isotype switching, and somatic hypermutation, thus creating "programmed immunity". The combination approach of bNAbs and CRISPR-Cas9 is considered promising because it is able to neutralize circulating viruses while removing latent proviruses, increasing the potential for functional cure. However, biological risks such as off-target effects, Cas9 immunogenicity, limitations of the delivery system, and the emergence of escape mutants remain challenges. This review shows that the integration of monoclonal antibodies with CRISPR-Cas9 opens up a new paradigm of HIV therapy, with the potential to improve efficacy, duration of protection, and decrease reliance on ART. Further research, including advanced phase clinical trials, is needed to ensure its safety, effectiveness, and feasibility of application in human populations.

Abstract

Habits of Mind (HoM) is an important thinking disposition that supports successful learning in higher education, especially in inquiry-based learning. This study aims to map the profile of students' habits of mind as a basis for developing inquiry-based learning strategies. The study used a quantitative descriptive approach involving 60 students in semesters I, III, V, and VII. Data were collected through an online questionnaire containing 16 indicators of habits of mind based on the Costa and Kallick framework, then analyzed using percentage scores based on semester and indicator. The results showed that students' habits of mind achievement was in the good category, with the highest scores in semesters I (81%) and VII (80%), while semesters III and V were in the sufficient category (74%). Indicators with the highest scores included listening with understanding and empathy (90%), striving for accuracy (85%), and persisting (84%), while the lowest scores were found in thinking flexibly (62%), thinking interdependently (69%), and finding humor (71%). These findings indicate that students possess strengths in perseverance, thoroughness, and empathy, but still need to strengthen their thinking flexibility and collaboration. Therefore, structured and collaborative inquiry-based learning is recommended to develop students' habits of mind in a more balanced manner.

Abstract

The finger length ratio (2D:4D) is often used as an indirect indicator to estimate the influence of hormones, especially prenatal sex hormones, which are thought to be related to physical variations such as height. This study aims to analyze the relationship between the index finger and ring finger length ratio (2D:4D) and the height of students at the University of Jambi. This study used a quantitative approach with a correlational design. The sample consisted of 37 students at the University of Jambi who were selected using purposive sampling. The inclusion criteria included students who were willing to participate, were in good physical health, and had no growth disorders or abnormalities of the fingers. Measurements were taken directly of the length of the index finger (2D) and ring finger (4D) on the right and left hands using calipers with an accuracy of 0.05 mm, while height was measured using a tape measure. Pearson's correlation analysis was used to determine the relationship between the 2D:4D ratio and height. The results showed that the relationship between height and the 2D:4D ratio on the right hand (r = 0.184; p = 0.276) and left hand (r = 0.233; p = 0.166) was positive but very weak and not statistically significant. These findings indicate that the 2D:4D ratio is not significantly related to the height of students at the University of Jambi.

Abstract

Sickle Cell Disease (SCD) is a monogenic disease due to a point mutation in the HBB gene that causes chronic hemolytic anemia and vaso-occlusive crisis, while conventional therapy is generally palliative. In the past decade, CRISPR-based gene editing has developed rapidly and given birth to three main platforms, namely CRISPR-Cas9, base editing, and prime editing which opens up opportunities for more curative therapies through fetal hemoglobin (HbF) reactivation or correction of genetic targets. This literature review aims to compare working principles, cutting-edge achievements, advantages, and limitations, as well as the ethical implications and potential integration of biology learning from the three technologies. The method used is a descriptive-comparative literature review of 2015-2025 publications from reputable databases (PubMed, Scopus, ScienceDirect, SpringerLink, and Nature Portfolio) which is selected based on relevance and quality. The results of the synthesis showed that CRISPR-Cas9 has reached the clinical stage through HbF-enhanced autotemcel (exa-cel/Casgevy) exagamglogen therapy and is reported to suppress vasoocclusive crises in most patients. Base editing offers base change without Double-Strand Break (DSB) and shows promising preclinical results, including HbS conversion strategies into antisickling variants (e.g. HbG-Makassar) as well as modulation of HbF regulators. Prime editing provides the ability to "rewrite" sequences without DSBs or separate DNA donors and shows preclinical evidence in hematopoietic stem cells and animal models, but efficiency, complexity of delivery, and long-term safety data remain challenges. This study emphasizes that strengthening ethical governance (safety, informed consent, and access fairness) needs to go hand in hand with innovation. In addition to biomedical relevance, the topic of SCD-gene editing has the potential to be an authentic context for developing students' genomic literacy, ethical reasoning, and critical thinking through the PjBL and SSI approaches.
