Background: The learning process emphasizes students' active involvement and is oriented towards applying the concept of learning by doing and prioritizing personal experiences through observing, asking, and communicating to increase student creativity. However, reality proves that the application and implementation of learning in schools are not as expected. Some problems include the learning process only focusing on completing the subject matter, not on forming an understanding of the subject matter for students. This study aimed to analyze the need to develop electronic teaching materials according to the needs of students based on problem-based learning (PBL) learning models in biology subjects at MAN 1 Palembang school. Methods: The research used a qualitative descriptive method with a survey method by conducting interviews and questionnaires with biology teachers and students. Questionnaires, observations, and interviews provided data collection techniques. Results: The results obtained are textbooks and learning videos are the teaching materials most often used by teachers using discovery learning and project-based learning (PjBL) models. Students' activeness can be seen when the discussion activities and presentations of assignments take place, but it does not make students think critically. Conclusion: Teachers want problem-based learning (PBL) electronic teaching materials so that students can learn the material earlier and improve learning outcomes in material that is difficult for students to understand.

Background: Plants’ response and antagonistic reaction against disease-causing organisms are two crucial characteristics of Plant Growth Promoting Bacteria (PGPB). Seventeen endophytic bacteria have been isolated from Musa balbisiana. However, the plants’ reaction against these isolates and their antagonistic activities against disease-causing organisms remained unknown. This study aims to (1) determine the sensitivity effect of endophytic bacteria isolates to tobacco and (2) test the antagonism of endophytic bacteria isolates against the blast disease actor, namely Pyricularia oryzae. Method: Sensitivity tests were performed by inoculating bacterial isolates into tobacco leaves with infiltration. Bacterial isolates were prepared with a minimum OD 600: 0.5. Then, a milliliter volume of each isolate was infiltrated into tobacco leaves from the abaxial side using a 3 mL syringe. The lesion on the tobacco leaves was observed seven days after inoculation (DAI). The antagonism test was carried out by growing Pyricularia oryzae on a PDA plate for seven days, subsequently transferred to an NA medium for three days then inoculated with endophytic bacteria. The assessed parameter of the antagonistic test was the formation of an inhibitory zone between endophytic bacteria and Pyricularia oryzae at 4 DAI. Results: No hypersensitive reaction of tobacco leaves against K117, K324, K38, K86, K18, K28, K102 isolates inoculation at 7 DAI. Furthermore, the antagonistic test indicated that all isolates inhibited the growth of Pyricularia oryzae, with the range of inhibition from 32.36 to 40.46%. Implication: Thus, these results revealed the PGPB characteristics in the newly isolated endophytic bacteria from the banana.

Latar Belakang: Tempat pemakaman umum (TPU) adalah tempat yang digunakan untuk penguburan jenazah dan terjadi penguraian jenazah secara aktif di dalamnya. Proses penguraian ini menghasilkan nutrisi dan mineral tanah yang dapat mendukung pertumbuhan mikroorganisme di dalam tanah termasuk bakteri yang bersifat patogen. Bakteri patogen memiliki dampak yang lebih parah apabila bakteri tersebut resisten terhadap antibiotik. Di Indonesia belum terdapat data mengenai penelitian ini sehingga penelitian ini bertujuan untuk mengetahui populasi bakteri tanah di area TPU dan resistensinya terhadap antibiotik.. Metode: Sampel tanah diambil di area TPU Bonoloyo, Surakarta, Jawa Tengah pada 3 titik masing-masing dari 2 kedalaman 20 dan 50 cm. Sampel tanah diinokulasikan pada media NA (Nutrient agar) menggunakan metode spread plate. Setelah 48 jam, dilakukan penghitungan koloni dan pengamatan morfologi koloni yang dilanjutkan dengan pewarnaan gram. Isolat bakteri yang berhasil diisolasi diuji resistensinya terhadap 3 jenis antibiotik. Hasil: Rerata populasi bakteri tanah pada blok 12, 17, dan 21 pada kedalaman 20 cm adalah 4 x x 10⁶; 8 x 10⁶; dan 1 x 10⁶ CFU/g, sedangkan pada kedalaman 50 cm adalah 2,3 x 10⁶; 6 x 10⁶; dan 4 x 10⁶ CFU/g. Morfologi koloni bakteri berbentuk irregular (26 isolat), elevasi flat (19 isolat), dan warna isolat didominasi warna putih. Hasil pewarnaan Gram diperoleh 23 isolat merupakan Gram negatif dan 22 isolat merupakan Gram positif dengan bentuk sel dominan berbentuk kokus. Uji resistensi terhadap antibiotik menunjukkan bahwa isolat-isolat bakteri tersebut sudah resisten terhadap ampisillin (28,9%), Bacitracin (64,4%), dan Cefepime (57,8%). Kesimpulan: Populasi bakteri tanah pemakaman di TPU Bonoloyo pada kedalaman berbeda tidak berbeda nyata dengan jumlah berkisar antara 1 – 8 x 10⁶ CFU/g.
背景:公共墓地(TPU)是埋葬尸体的地方，是活动尸体分解的地方。这种分解过程产生土壤中的营养和矿物质，促进土壤中微生物的生长，包括病原细菌。如果病原体对抗生素有抗药性，其影响会更大。在印度尼西亚，目前还没有关于这一研究的数据，因此这项研究旨在确定TPU地区的土壤细菌数量及其对抗生素的耐药性。方法:在爪哇岛中部的苏拉卡塔港博奥罗约地区采集的土壤样本，每段20到50厘米。用膨胀板的方法在NA介质上克隆土壤样本。48小时后，对菌落进行了分级计算和对菌落形态的观察，然后是克染色。成功分离的细菌分离体对三种抗生素的耐药性进行了测试。结果:平均土壤细菌种群在街区、12、17和21个深度20厘米x是x 4 10⁶;8乘以10⁶;和1×10⁶CFU / g,而深达50厘米是2.3×10⁶;6 x 10⁶;和4 x 10⁶CFU / g。irregular菌落菌落形状为irused (26 isolat)、圆海拔(19 isolat)和异色以白色为主。克染色研究发现23个异构体是阴性的克，22个异构体是阳性的克，形状像凝聚物。抗生素耐药性测试表明，细菌的异化已经对氨苄(289%)、杆菌素(64.4%)和扑热息痛(57.8%)有抗药性。结论:在远离投票箱Bonoloyo葬礼不同深度土壤细菌种群数量不等的情况下真的没有什么不同1—8乘以10⁶CFU / g。

Proses penguraian ini menghasilkan nutrisi dan mineral tanah yang dapat mendukung pertumbuhan mikroorganisme di dalam tanah termasuk bakteri yang bersifat patogen. Bakteri patogen memiliki dampak yang lebih parah apabila bakteri tersebut resisten terhadap antibiotik. Di Indonesia belum terdapat data mengenai penelitian ini sehingga penelitian ini bertujuan untuk mengetahui populasi bakteri tanah di area TPU dan resistensinya terhadap antibiotik.. Metode: Sampel tanah diambil di area TPU Bonoloyo, Surakarta, Jawa Tengah pada 3 titik masing-masing dari 2 kedalaman 20 dan 50 cm. Sampel tanah diinokulasikan pada media NA (Nutrient agar) menggunakan metode spread plate. Setelah 48 jam, dilakukan penghitungan koloni dan pengamatan morfologi koloni yang dilanjutkan dengan pewarnaan gram. Isolat bakteri yang berhasil diisolasi diuji resistensinya terhadap 3 jenis antibiotik. Hasil: Rerata populasi bakteri tanah pada blok 12, 17, dan 21 pada kedalaman 20 cm adalah 4 x x 10⁶; 8 x 10⁶; dan 1 x 10⁶ CFU/g, sedangkan pada kedalaman 50 cm adalah 2,3 x 10⁶; 6 x 10⁶; dan 4 x 10⁶ CFU/g. Morfologi koloni bakteri berbentuk irregular (26 isolat), elevasi flat (19 isolat), dan warna isolat didominasi warna putih. Hasil pewarnaan Gram diperoleh 23 isolat merupakan Gram negatif dan 22 isolat merupakan Gram positif dengan bentuk sel dominan berbentuk kokus. Uji resistensi terhadap antibiotik menunjukkan bahwa isolat-isolat bakteri tersebut sudah resisten terhadap ampisillin (28,9%), Bacitracin (64,4%), dan Cefepime (57,8%). Kesimpulan: Populasi bakteri tanah pemakaman di TPU Bonoloyo pada kedalaman berbeda tidak berbeda nyata dengan jumlah berkisar antara 1 – 8 x 10⁶ CFU/g.

Background: This study aims to determine the influence of applying the Inquiry Lesson learning model on the scientific reasoning abilities of Grade X students. Method: This type of research uses a quasi-experiment. The sample for this research was A total of 55 students in the science program grade 10 at one of the Madrasah Aliyah Public Schools (MAN) were involved. The instrument used is in the form of scientific reasoning ability test questions in the form of reasoned multiple-choice questions of 15 questions. The research design used is the Non-equivalent Control Group. The second instrument uses a student response questionnaire to learning using the inquiry lesson learning model, which consists of 12 questions. Results: The average N-Gain score was 0.48 in the moderate category, and the scientific reasoning abilities of students in the control class produced an average pretest score of 56.12 and a post-test average score of 70.13 with an average score of 70.13. N-Gain score of 0.32. The hypothesis test obtained a significance value of sig (2-tailed) 0.004, then H0 was rejected, and H1 was accepted. The emergence of scientific reasoning abilities of experimental class students on each indicator varies but generally has an N-Gain score in the moderate category. Student response questionnaires regarding the inquiry lesson learning model showed an average score in the excellent class (61-80). Conclusion: the conclusion in this study is that there is an increase in inquiry lesson learning on students' scientific reasoning abilities in Grade X ecosystem material.
