Abstract

The existence of agricultural land is indirectly related to the environment. The existence of agricultural land in terms of environmental aspects can provide five types of benefits, namely preventing flooding, controlling water balance, preventing erosion, and reducing environmental pollution from household waste. This research aims to analyze environmental changes in the conversion of agricultural land to non-agricultural activities in Palembang City. This research uses quantitative methods, analytical quantitative research is conducted to accept or reject hypotheses that are described by significance values. The research also used qualitative methods by conducting measured interviews with 250 respondents. The research was conducted in May 2023 in three sub-districts in Palembang City, namely Kalidoni, Kertapati, and Gandus sub-districts. The environmental indicators used as a reference include water quality, air quality, soil conditions, traffic conditions, runoff water conditions, plant conditions, and animal conditions. The results showed that the condition of plant environmental quality in the Gandus and Kalidoni sub-districts is classified as poor, while the Kertapati sub-district is in the good category. While the condition of the environmental quality of animal indicators in the Kertapati and Kalidoni sub-districts is in the good enough category, but in the Gandus sub-district it is in the bad category. Dragonfly populations will be high if the habitat conditions are very suitable. This means that there are still streams or puddles that are still clean and food is available. This clean water is the place for dragonfly eggs and images for further development. So if the dragonfly population at a location is still high, it means that the water conditions at that location are still not polluted.

Abstract

Orthohantavirus is an RNA virus that causes Hemorrhagic Fever with Renal Syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS). Humans can become infected with orthohantaviruses by inhaling virus particles from the urine, saliva, and feces of infective reservoir hosts. Small mammals from the orders Rodensia, Eulipotyphla, and Chiroptera are the main reservoirs of orthohantaviruses. This study aims to detect and calculate the incidence of orthohantavirus in reservoir hosts in Semarang City. The research was conducted descriptively analytically with a cross-sectional study design. The research population was all mice and shrews in the research location (Gayamsari and Tlogosari subdistricts), and the samples were caught mice and shrews (84). The research was carried out in May-September 2023. Orthohantavirus detection was carried out using the Nested PCR test (pre denaturation, denaturation, annealing and extension). A total of 84 individuals were captured, consisting of Rattus novergicus, Rattus tanezumi and Suncus murinus. Orthohantavirus in this study was successfully detected in Rattus norvegicus. The results of the study showed that the incidence of orthohantavirus in Gayamsari Village was (11.1%), Tlogosari Village (2.78%), and the overall total was (2.38%). It is necessary to control mice to prevent transmission of orthohantavirus.

Abstract

The objective of this study is to explore the implementation of the Independent Learning Curriculum (Kurikulum Merdeka Belajar) and the challenges faced by teachers during its implementation. This research adopts a qualitative approach with a descriptive research design. The subjects of the study are the School Principal and Biology teachers at SMA Negeri 2 Percut Sei Tuan. Data collection involved observation, interviews, and documentation. Data analysis techniques included data reduction, data presentation, and drawing conclusions. Data validity was ensured through Technique Triangulation. The findings indicate that SMA Negeri 2 Percut Sei Tuan has implemented various aspects related to the Independent Learning Curriculum, one of which is the application of the Pancasila Student Profile through Project-Based Learning. Based on interviews, teachers encounter challenges in determining assessments that align with the intended learning objectives, especially in project-based learning scenarios. This confusion stems from the variety of assessment types such as presentations, projects, products, oral assessments, written assessments, and others. To address these issues, both the School Principal and teachers attend monthly training sessions as part of the Teacher Working Group (Kelompok Kerja Guru, KKG) to tackle problems and enhance teacher competence in teaching and learning activities.

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.
