No full textThis study aims to determine the effectiveness of Augmented Reality (AR)-based learning media on students' mathematics learning outcomes of flat-sided space building material. This research uses a quasi-experiment method with a non-equivalent control group design. The subjects of this study were VII grade students of SMP Negeri 1 Gunungsari as many as two classes, namely the experimental class and the control class. Where the experimental class is given Augmented Reality-based learning media while the control class is given website-based learning media. This study was conducted for 5 meetings, starting with giving a pretest, followed by learning by implementing learning media for 3 meetings in each class and giving a questionnaire of learning interest for the experimental class. The last meeting was held posttest to determine student learning outcomes. Data analysis used independent sample t-test and N-Gain Mean analysis. The results showed that AR media was significantly effective in improving students' math learning outcomes (P < 0.005), with the N-Gain category of the experimental class classified as high and effective, while the control class was categorized as less effective. In addition, the use of AR media also increases students' interest in learning, with a very good category.Abstrak

Agreement of Non-Contact Infrared Thermometer Measurement Results with Digital Axillary Thermometer in Neonates at the Pejeruk Community Health
Get PDFNCIT has several advantages, such as quick measurement time, no need for contact between the device and the patient, and greater comfort for patients compared to measuring temperature using TDA or rectal digital thermometers. These advantages make NCIT suitable for use in PKM. However, previous research on the comparability of NCIT measurement results with TDA in neonates is limited and shows varying results. This study aims to determine the agreement of NCIT measurement results with TDA measurement results in neonates. The study is an analytical observational study with a cross-sectional design. 25 neonates participated in this study, with some having their temperature measured only once and others more than once, according to an agreement with their guardians. A total of 62 temperature measurement samples were taken after going through the inclusion and exclusion process. The measuring instrument used was the digital axillary thermometer (TDA), which served as the reference. Additionally, three types of non-contact infrared thermometers (NCITs) were used to assess their agreement for this study. The sample data was analyzed using the One-Sample T-test, Intraclass Correlation Coefficient (ICC) method, and Bland Altman Plot. The ICC results indicated poor agreement of each NCIT with the TDA. The One Sample T-test indicates that of of the NCIT used does not have statistically significant differences compared to TDA, whereas two other types of NCIT do have statistically significant differences compared to TDA, The Bland Altman Plot analysis shows that the Limits of Agreement for each type of NCIT with TDA are still wide. From these results, it is concluded that these three types of NCIT cannot replace TDA as a body temperature measurement tool for neonates
Formulation of Castor Leaf Extract as a Propestic Pesticide to Control Shallot Caterpillar Pest Spodoptera Exigua Hubn
Get PDFOne of the crops that can be cultivated in drylands is shallots. Spodoptera exigua Hubn is the main pest that attacks shallot plants. The purpose of writing this article is to review the results of previous research on jatropha leaves as a vegetable peticide with various extracts so that it can be known which extract is the most optimal as a control of onion caterpillar pests. The method used in this writing is to collect and process data sources from previous research published in scientific articles, books, and discussion results. The results showed that active compounds such as saponins, flavonoids, alkaloids, tannins, and phenols in Jatropha leaves extract significantly increased pest mortality and decreased pest feeding activity. Higher extract concentrations were directly proportional to greater negative effects on pests, highlighting the potential of falak nut leaves as an effective and environmentally friendly plant-based pesticide

This study aimed to utilize these materials to create teatrasi herbal tea and evaluate its antioxidant and flavonoid content, sensory attributes, and overall acceptability. method and analysis the process involved material preparation, thorough washing, drying at specific temperatures and times, grinding, and packaging. Three formulations were tested, with Formula 3 (40% corn silk, 20% papaya seeds, and 40% dragon fruit peels) being the most favored based on hedonic tests. Antioxidant and flavonoid analyses confirmed strong antioxidant activity (IC50: 89.27 ppm) and high flavonoid content (884.64 mg/L QE) in Formula 3. Results organoleptic tests highlighted its distinctive corn silk aroma, reddish-brown color, and mild flavor. Respondents rated its aroma, color, and taste with favorability levels of 93.75%, 90.62%, and 92.70%, respectively, achieving an overall acceptance rate of 92.29%. Conclusion, this research demonstrates the potential of converting underutilized natural resources into sustainable, health-enhancing beverages
Diversity of Bryophytes Based on Substrate Types in the Karangkamulyan Tourist Area, Ciamis Regency
Get PDFIndonesia is renowned as a megabiodiversity country with a wealth of flora, including the diversity of bryophytes. These plants play a crucial role in ecosystems, such as oxygen production, erosion control, and water absorption. This study aims to analyze the diversity of bryophytes in the Karangkamulyan Tourism Area, Ciamis Regency, and to examine their diversity based on substrate types. Karangkamulyan is a cultural and natural conservation area covering 25.5 hectares with a climate and conditions that support bryophyte growth. The research utilized an exploratory method with random sampling at three selected points within the area. Morphological and anatomical analyses were conducted to identify species, and the percentage of occurrence was analyzed based on substrate types. The results revealed the presence of 15 species belonging to 12 families of bryophytes inhabiting various substrates such as soil, rocks, and tree trunks. The identified bryophytes included 6 liverworts (Marchantiophyta): Dumortiera hirsuta, Marchantia emarginata, Riccia gangetica, Heteroscyphus argutus, Heteroscyphus coalitus, and Schiffneriolejeunea sp.; and 9 mosses (Bryophyta): Neckeropsis undulata, Thuidium plumulosum, Ectropothecium falciforme, Fissidens sp., Fissidens flaccidus, Calymperes sp., Hyophila sp., Barbula sp., and Bryum sp. Based on substrate types, 91 occurrences were recorded, consisting of 25% terrestrial bryophytes (23 occurrences), 55% epiphytic bryophytes (50 occurrences), and 20% epilithic bryophytes (18 occurrences)
Primer Design of Sumatran Striped Rabbit (Nesolagus netscheri Schlegel, 1880) using Primer-BLAST and AliView Program
Get PDFThe Sumatran striped rabbit (Nesolagus netscheri) lacks specific primers to amplify the chytochrome oxidase 1 (CO1) gene and the chytochrome b (cytb) gene, at present. Therefore, it is important to design primers to amplify the CO1 gene and cytb gene in N. netscheri. The aim of this study is to compare the primer design methods used, namely Primer-BLAST and AliView programs, to design specific primers for the chytochrome oxidase 1 (CO1) and chytochrome b (cytb) genes in N. netscheri. This research was conducted using the descriptive method with molecular observation. In this study, CO1 gene primers, namely [(forward: 5' TGTATGATATGGGGGAGGGC 3'), (reverse: 5' TGGTCCGTCCTTATTACAGCG 3')] and cytochrome b (cytb) gene primers, namely [(forward: CCAGCTCCATCCAATATCTC, (reverse: 5' GTTAGGGTTAGAAGGTCTGC 3')] and showed that primer design using the AliView program produced specific primers in the genus Nesolagus. The conclusion of this study is that primers designed using the AliView program are more specific than those designed using Primer-BLAST
Literatur Review: Analysis of Essential Oil Secondary Metabolite Content in Several Plants
