Abstract

Vocational high schools (SMK) are formal educational institutions that play a crucial role in preparing students to be better prepared to face future challenges. Specific training or skills programs in certain fields, such as health, can be provided to students as provisions before entering the workforce. By providing a deeper understanding of microbiology testing from an early age, health vocational school graduates can be better prepared to face industry demands and actively improve safety standards in the health care sector. The safety and effectiveness of medical devices are highly dependent on microbiological control. The curriculum provides students with critical skills and insights related to microbiological testing on various medical devices. The manufacturing process of medical devices, especially Class II and III devices, requires a high level of sterility since they interact with blood, vessels, or internal organs of the human body. Therefore, microbiological testing is essential to ensure sterility. This review analyzes various microbiological testing methods used to ensure the safety of medical devices, focusing on Sterility Testing, Bioburden Testing, and Endotoxin Testing. The purpose of this review article is to provide information on microbiological tests applicable to sterile product evaluation. The method used in this study involves a literature review of Indonesian National Standards (SNI), Indonesian Pharmacopoeia (FI), and international journals. Various studies indicate that sterility testing is performed to ensure that medical device products are free from microbial contamination after sterilization treatment with ethylene oxide (EO) machines. Meanwhile, Bioburden Testing is conducted to determine the bacterial load on Medical Devices before sterilization with EO machines. Endotoxin Testing aims to ensure that Medical Devices are free from bacteria, particularly Gram-negative bacteria, which are pyrogenic and produce toxins in the body.

Abstract

Plant meristems harbor stem cells that maintain their capacity for self-renewal while generating daughter cells that differentiate into various tissues and organs. This delicate balance between self-renewal and differentiation is governed by complex molecular and cellular mechanisms. This literature review synthesizes recent advances in understanding the regulatory networks controlling stem cell maintenance in plant meristems, focusing on the shoot apical meristem (SAM), root apical meristem (RAM), and cambium. The review examines key signaling pathways, transcriptional networks, epigenetic regulation, hormonal control, and cellular communication mechanisms that coordinate stem cell maintenance. Recent technological advances in single-cell sequencing, live imaging, and computational modeling have revealed unprecedented insights into meristem function. Understanding these mechanisms has important implications for crop improvement, sustainable agriculture, and plant adaptation to changing environments. This comprehensive review integrates findings from over 50 recent studies to provide a current understanding of the molecular and cellular basis of plant stem cell maintenance

Abstract

The 21st century demands that learning in schools must be able to encourage students to develop their critical and creative thinking skills in order to be able to compete in the global world. But on the other hand, it is also expected that students do not forget their national identity. So that biology material in schools that is very closely related to the surrounding environment needs to be linked to existing local wisdom. Therefore, an appropriate learning strategy is needed to accommodate all these interests. This study aims to determine the effectiveness of the SETS (Science Environment Technology Society) model containing local wisdom on creative thinking skills in environmental material. Using quasi-experimental research with a nonequivalent pretest-posttest control group design. The population is all students of class X SMAN 7 Pekanbaru with a sample of two classes taken randomly. Data were collected through tests with multiple-choice test instruments. Data analysis with parametric t-test statistics. The results of the study showed that the average N-Gain of the control class was 0.46 (moderate) and the experimental class was 0.51 (moderate). The results of the N-Gain t-test obtained a sig value. (2-tailed) 0.000<0.05 then reject Ho. This means that the application of SETS learning containing local wisdom is effective in increasing students' creative thinking skills.

Abstract

Phyllotaxis, or the pattern of leaf arrangement along a plant stem, plays a crucial role in physiological efficiency and morphological adaptation. This study aims to examine the variation in phyllotactic patterns among plants, identify their relationship with morphological symmetry, and provide examples of species that exhibit each pattern. Through a systematic literature review method, various relevant scientific sources on phyllotaxis and leaf morphological symmetry were analyzed, including journals, textbooks, and previous review articles. The analysis revealed two main categories of phyllotaxis: alternate and whorled. In alternate phyllotaxis, patterns such as distichous, spiral, semidecussate, and orixate arrangements were identified, whereas whorled phyllotaxis included decussate, tricussate, and tetracussate patterns. Each pattern exhibits distinct symmetry characteristics, including reflection, rotational, and spiral symmetries. The study also found that variations in phyllotactic patterns demonstrate profound geometric regularities, which are associated with plant adaptive strategies for light capture and internal resource distribution. This review provides new insights into the understanding of phyllotaxis in the context of morphological geometry and the distribution of plant species exhibiting each pattern.

Abstract

In every higher plant, there will be a change from vegetative to generative. In this change, a series of new structures will be formed, namely flowers. Flowers are an expression of genes that were not previously expressed. The flowering stage is one of the stages of the development phase that needs to be considered in plants. Therefore, it is necessary to understand the factors that influence the flowering stage. This study aims to determine the factors that influence flowering. The method used in this article is through journal reviews. The number of journal articles reviewed and analyzed was 15 journal articles that had relevant topics. Then the results of the study are presented in descriptive form and presented in a table. Based on the results of the literature review, it is known that there are many factors that influence the flowering stage, including temperature and humidity, paclobutrazol, the influence of auxin and gibberellin growth regulators, types of containers and fertilizer concentrations, photoperiods, various types of fertilizers, eco enzymes and pinching.

Abstract

Plant development involves the results of complex interactions between genetic regulation, hormones, and environmental responses. This article aims to provide an analysis of plant development coordination and its regulatory mechanisms, to reveal how plants coordinate their growth and adapt to dynamic environments. The method used is a descriptive qualitative approach using a systematic literature review method to identify, classify, and analyze. Article searches were carried out through various scientific databases such as Google Scholar, ScienceDirect and pubmed. Plant development coordination involves complex growth and differentiation processes. Starting with germination triggered by water and enzyme activity, followed by primary growth through apical meristems that produce plant organs (roots, stems, leaves, flowers, fruits, and seeds) and secondary growth, which involves lateral meristems that cause thickening of stems and roots. In addition, genetic regulation functions as a mechanism that allows plants to grow, develop, and respond to the environment effectively. Hormones such as auxins, gibberellins, cytokinins, ethylene, and abscisic acid work together to regulate growth and stress responses. Plants can also remember previous stress through epigenetic modifications to increase their resilience to repeated stress. All of these systems allow plants to adapt and survive in changing environmental conditions.

Abstract

ABSTRACT: Soil bugs or rice black bugs are one of the insects that like to suck rice plants. These insects suck rice plants in the vegetative and generative phases and have caused huge economic losses. This research aims to identify and study the appropriate of Soil Bugs species from several rice fields in Lubuk Sikarah District, Solok City, West Sumatra. This research uses a sampling method using light traps at night.  Morphological identification of rice black bug samples using a light microscope with the weakest magnification (4x10). The results showed that there were five species of soil bugs obtained, namely Scotinophara coarctata, S. zamboanga, S. trifurcata, S. alegria and S. manguindanaoana. Soil bugs are more commonly found in generative rice plants due to the suitability of food and environmental factors. The amount of S. coarctata are the most dominant because it is the most phytophagous of other species of rice black bugs. The characteristics of soil bugs observed were different distance between the ocelli, length of the third and fourth segments on the antennae, shape of the tubercle antiniferous, shape of the anterolateral pronotum, in the amount and shape of longitudinal veins and closed marginal cells in the forewing venation and different shape of abdominal tergit X.

Abstract

Indonesia's biodiversity continues to decline annually. One of the causes is the increase in tourist areas that ignore ecological values, reduce green open spaces, and only focus on economic gain. Learning can utilize local potential with the Natural Exploration model in the surrounding area so that students not only learn about plant diversity from books but also have knowledge and sensitivity to the surrounding environment. In the higher plant systematics course, an outdoor learning model is applied so that learning objectives can be achieved. Based on observations made in the higher plant systematics course, data was obtained that learning has not utilized existing local potential and still refers to textbooks with general material about plants. Furthermore, in the Biology Education Study Program at Pasir Pengaraian University, there is no E-Module based on local plants using the Experiential Natural Exploration (EJAS) model. The purpose of this study is to develop teaching materials for the higher plant systematics course based on EJAS. The method used in this study is development research with the ADDIE model. The results of this study obtained that the e-module based on experiential exploration of the surrounding nature (EJAS) for the higher plant systematics course was overall very suitable for use with an average value of 90.4%.
