Abstract

The application of science and technology (IPTEK) in education has generated several learning innovations, including the use of media in learning. The purpose of this research was to develop a product in the form of project-based learning (PjBL) animated videos based on the circulatory system material for grade XI in high schools, which is valid, practical, and suitable for use. Research and development (R&D) activities included data collection on student and teacher needs. The development phase aimed to produce learning media products involving media experts, subject matter experts, and biology teachers. Subsequently, the product was tested with 12 students in a limited group and then with 38 students in a broader group to determine its media feasibility. The development of PjBL-based animated video products was evaluated using instruments covering several aspects: validation sheets for media, including text composition balance, images, sound, and video, color selection, physical criteria, practicality, and long-term usefulness. Validation sheets for content included aspects of learning promotion, curiosity enhancement, presentation support, material accuracy, and student engagement. Practitioner validation sheets covered material, language, and presentation aspects, while student response questionnaires addressed material, language, and presentation. Based on the expert media validation assessment recapitulation, the overall score indicated the product was highly valid and suitable for use in learning, with an average percentage of 84.00%. Similarly, the expert content validation recapitulation showed the product to be highly valid and suitable for use in learning, with an average percentage of 88.00%. The practitioner assessment by biology teachers indicated the product was highly practical and suitable for use in learning without revision, with an average percentage of 91.19%. Additionally, the limited and broad group product tests showed an average student response rate of 85.00%, indicating that the developed animated video is suitable for use in learning without revision.

Abstract

Diabetes mellitus (DM) is a metabolic disorder that is accompanied  by an increased glucose in the blood or called hyperglycemia. Diabetes can be caused by problems with the pancreas not being able to produce insulin, insufficient insulin secretion, imperfect insulin action, or both. When blood glucose is left elevated for a long time, it can cause complications such as gangrene. Diabetic gangrene is one of the complications caused by tissue damage. Gangrene occurs due to neuropathy and vascular disorders, usually in the peripheral areas of the body. Bacteria found in diabetic wounds are bacteria that produce biofilms such as Staphylococcus aureus. Staphylococcus aureus can release exotoxins such as leukocidin. Leucosidine lyses PMNs and releases ROS which will then induce a cytokine response such as interleukin-6 which will increase CRP levels. hs-CRP is a high precision CRP measurement even at low concentrations.This study aims to determine the correlation between hs-CRP levels and the presence of Staphylococcus aureus in type II diabetes mellitus gangrene wounds. The research design used is observational analytical using a cross sectional approach and accidental sampling. There were 16 research respondents with increased hs-CRP levels in 15 respondents and 9 respondents with Staphylococcus aureus bacteria. Correlation test with a value of p = <0.05 (p=0.032) means that there is a correlation between hs-CRP and the presence of Staphylococcus aureus in type II diabetes mellitus gangrene wounds.

Abstract

Rural landscapes are part of man-made landscapes as a result of conversion of natural landscapes due to human needs. Birds respond positively to these changes as ecosystem components that are able to adapt and survive in rural landscapes. The countryside in the northern part of the Sukabumi is located between the natural landscape of Mount Gede and the rural landscape of Sukabumi City. The research aims to analyze the diversity of bird in the rural landscape of the Sukabumi Area. Research in the form of direct observation was carried out in February-May 2022.  Bird data was taken using the point count method in the morning and evening. Qualitative analysis was carried out by describing and looking at the protection status. Quantitative analysis was carried out using (1) chi-square test, (2) Margalef Index (DMg), (3) Shannon-Wiener Index (H'), (4) venness index (E), and similarity index community (IS). There were 43 species of birds found from nine orders and 23 families. Five species birds are protected by the Indonesian Government. A total of 25 species (58%) are members of the Order Passeriformes. The majority are terrestrial birds, there is only one species that is considered a water bird, namely Von Schrenck’s Bittern (Ixobrychus eurhythmus). The DMg value obtained was 2.23-6.45, while the H' value obtained was 1.70-3.24, while the E value obtained was 0.74-09.90.
