Abstract

Rice (Oryza sativa L.) is a strategic food commodity in Indonesia, with demand continuing to rise in line with population growth. Efforts to increase rice production through intensification often rely on the use of inorganic fertilizers, which have a negative impact on soil fertility. One alternative to reduce this dependence is the use of microbial-based biofertilizers, such as Trichoderma asperellum, which plays a role in improving nutrient uptake and plant growth. However, the formulation of T. asperellum in conventional media such as PDA is still ineffective in the field due to its relatively high cost. This study was conducted to examine the contribution of a red glutinous rice-based T. asperellum formula with the addition of ecoenzyme to the vegetative growth of paddy rice (Oryza sativa L.). The study was designed using a completely randomized design (CRD) with six treatments of formula composition and NPK fertilizer and five replicates. The parameters observed included plant height and number of tillers at 3, 5, and 7 weeks after planting (WAP). The data were analyzed using ANOVA and Duncan's test at a 5% level. The results showed that the treatments had a significant effect on the vegetative growth of rice. Treatment P3 (60% formula + 40% NPK) produced the highest plant height (131.43 cm) at 7 weeks after planting, while treatment P2 (80% formula + 20% NPK) produced the highest number of tillers (60.33 tillers per clump) in the fifth week. These findings indicate a synergy between the biological activity of T. asperellum and NPK fertilizer, as well as the potential for reducing the use of inorganic fertilizers without decreasing the vegetative growth of rice.

Abstract

This research aims to analyze the quality of scientific literacy questions on biodiversity material using the ANATES application. ANATES (Test Analysis) is a computer application specifically developed to measure and evaluate the quality of exam questions. The research was conducted by collecting data from a collection of scientific literacy questions on biodiversity material and then analyzing it using ANATES. This type of research is descriptive quantitative. This research was carried out at Padang State University. The research subjects are Biology students in 2023 who are taking basic science courses. The population is all biology students in 2023 who are taking basic science courses. In this case, the sample used was only one class, namely biology education class C, totaling 35 people. The instrument used was scientific literacy questions on biodiversity material, totaling 25 questions. Next, the items are analyzed using ANATES to evaluate validity, reliability, level of difficulty, discriminating power, and distractor quality. The results of the analysis provide an in-depth picture of the quality of the scientific literacy questions on biodiversity material. It is hoped that the findings of this research can contribute to the development of better evaluation instruments for measuring students' understanding of biodiversity material. The implications of this research can be used by teachers, curriculum developers, and educational researchers to improve the quality of science learning at the secondary education level

Abstract

Increasingly developing technology encourages educators to use it in the learning process as a learning medium in order to increase student’s interest in learning. However, currently there are still many who do not optimally use technology-based learning media. The learning media used is monotonous and unable to visualize the material on the excretion system and coordination system in humans. This has an impact on student learning outcomes which are still below the school's Minimum Completion Criteria. Therefore, technology-based learning media such as e-modules in the form of flipbooks are needed. This research aims to produce an Android-based e-module in the form of a flipbook on excretion system and coordination system material that is valid, practical and effective. The type of research used is development research using the Plomp development model which consists of three stages, namely the initial investigation stage, the development stage (prototyping), and the assessment stage. The instruments used were teacher interview guide instrument sheets, student questionnaire sheets, self-evaluation sheets, and e-module validation sheets by experts, as well as e-module practicality assessment sheets in the form of flipbooks filled in by teachers and students. The subjects of this research were class XI high school students. The research object is an Android based e-module in the form of a flipbook on excretion system and coordination system material. The research results show that the Android based e-module in the form of a flipbook obtained very valid criteria validity results with a value of 86.76% and 89.06%, practicality results by teachers and students with very practical criteria with a value of 84.17% and 86.43%. Based on the T test carried out, there is a difference in value between the experimental class and the control class, namely a significance of 0.048 in the excretion system material and 0.003 in the coordination system material. Thus, Android-based e-modules in the form of flipbooks can improve students learning competence.

Abstract

Keamanan jajanan sekolah menjadi perhatian utama bagi orang tua, pendidik, dan pengelola sekolah dasar karena risiko kontaminasi oleh bahan biologis, fisik, dan kimia yang dapat membahayakan kesehatan anak. Penelitian ini bertujuan untuk mendeteksi keberadaan bakteri Staphylococcus aureus pada jajanan di SD Negeri 19 Air Tawar Barat Padang. Isolasi Staphylococcus aureus dilakukan terhadap 3 jenis jajanan dan medium yang digunakan Mannitol Salt Agar (MSA). Pengamatan penelitian adalah jumlah bakteri Staphylococcus aureus, pengamatan makroskopis dan mikroskopisnya. Hasil penelitian menunjukkan bahwa semua sampel jajanan dari SD Negeri 19 Air Tawar Barat Padang mengandung bakteri Staphylococcus aureus. Morfologi makroskopisnya beragam: pada sampel K1 (tahu isi), terdapat 49.105 CFU dengan ciri-ciri serupa pada sampel K2 (shanghai), sedangkan pada sampel K3 (sosis goreng), terdapat 25.105 CFU dengan karakteristik yang berbeda. Secara mikroskopis, bentuk dan susunan bakteri S.aureus  tetap konsisten sebagai coccus dengan susunan stafilokokus.
