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

Abstract – SD Negeri 12 Padang Panjang is one of the schools that has made efforts to implement the Adiwiyata program. In 2024, the school represented the city of Padang Panjang in the Adiwiyata competition at the West Sumatra provincial level; however, it did not achieve optimal results. For the 2025 Adiwiyata program, SD Negeri 12 has set a target to become the provincial representative of West Sumatra. Based on the evaluation results from 2024, it was found that the assessment indicator for Participatory-Based Environmental Activities needs improvement. One activity that can support this effort is hydroponic cultivation. A hydroponic cultivation training was conducted by 26 fifth-grade students. The training included both theoretical material and hands-on practice in cultivating green vegetables using a hydroponic system. The training was guided by two experts who are competent in the field. This training successfully increased students' knowledge of hydroponic vegetable cultivation. Moreover, over 90% of the participants demonstrated teamwork and developed a greater awareness of environmental care. This outcome is a significant contribution to supporting SD Negeri 12 Padang Panjang Barat’s efforts toward achieving Adiwiyata School status.

Abstract

Phosphate is a vital nutrient required for plants, yet its presence in the soil is frequently limited due to being held by specific ions. Microorganisms that solubilize phosphate, particularly fluorescent Pseudomonas, are considered among the most efficient agents for phosphate solubilization. This research intends to assess the capacity of six fluorescent Pseudomonas isolates derived from the rhizosphere of different plants to solubilize phosphate, and to analyze their IKF values. The research was carried out descriptively from June to August 2025 at the Plant Physiology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University. Observations were conducted by noticing the development of clear zones and determining the IKF values. The findings indicated that every isolate, specifically PfPj1, PfS36, PfLAHP2, PfCas, PfS31, and PfKd7, was capable of solubilizing phosphate. The highest IKF value was found in isolate PfKd7 (4.91), whereas the lowest was recorded for PfS36 (4.08). Variations in IKF values indicate differences in the capacity of each isolate to release organic acids, which are involved in the phosphate solubilization process. This discovery reinforces the capability of fluorescent Pseudomonas as an eco-friendly biological agent to enhance phosphorus availability.

Abstract

Antimicrobial resistance is increasing every year. New and better antimicrobial sources are needed. One source of antimicrobials that can be explored is from endophytic bacteria. This study aims to test the ability of fluorescent Pseudomonas endophytic bacteria from the roots of plantain lemongrass in producing antimicrobial compounds. The type of research is descriptive. The antimicrobial activity of fluorescent Pseudomonas isolates was tested using the point inoculation method using test microbes E. coli, S. aureus and C. albicans. The clear zone was observed after 24 hours. The results showed that fluorescent Pseudomonas isolates were able to inhibit E. coli with a diameter of 3.9 mm found in isolate 51. S. aureus bacteria had an inhibition zone of 9.4 mm in isolate 89. Interesting results were shown by isolate 51 in inhibiting C. albicans with an inhibition zone diameter of 29.9 mm. These differences in response are thought to be related to variations in cell wall structure and the presence of an outer membrane in Gram-negative bacteria, which inhibits the penetration of active compounds. Overall, fluorescent Pseudomonas endophytic bacteria from the roots of the plantain have the potential to be developed as a source of new antifungal candidates against C. albicans, while their antibacterial activity still needs to be optimized through compound purification and further testing.

Abstract

Patchouli (Pogestemon cablin Benth) is a cultivated plant that can produce oil and generate income for farmers. However, attacks by plant pests (OPT) often pose a challenge to patchouli production in Indonesia. One organism that causes wilt disease in patchouli plants is the bacterium Ralstonia solanaceaerum. Therefore, more environmentally friendly and sustainable control methods are needed. One strategy is the use of biological agents, especially antagonistic rhizosphere bacteria such as fluorescent pseudomonas. This study was conducted from June to August 2025 at the Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. This study used a completely randomized design (CRD) as the experimental design. In this study, there were 6 treatments (different isolates), each repeated 3 times. The parameter observed was the formation of an inhibition zone using the disc diffusion method. The data were analyzed using analysis of variance (ANOVA). If there were significant differences, Duncan's New Multiple Range Test (DNMRT) was used at a 5% level. Based on the results and discussions, it can be concluded that all fluorescent Pseudomonas isolates tested have the ability to inhibit R. solanaceaerum, the cause of wilt disease in patchouli plants. The isolate with the best ability to inhibit the growth of R. solanaceaerum on patchouli plants was isolate Pf S36 with an inhibition zone of 20.37 mm, but there was no significant difference between the other isolates because the inhibition effectiveness was relatively uniform.

Abstract

Penyakit layu bakteri yang disebabkan oleh Ralstonia solanacearum merupakan salah satu kendala utama dalam budidaya tomat dan nilam karena mampu menurunkan produktivitas secara signifikan. Penggunaan agen hayati seperti pseudomonas berfluoresen menjadi alternatif pengendalian yang lebih aman dan ramah lingkungan. Penelitian ini dilakukan untuk mengetahui kemampuan antagonis tujuh isolat bakteri endofit pseudomonas berfluoresen yang berasal dari akar pisang buai dalam menghambat pertumbuhan R. solanacearum yang menginfeksi tomat dan nilam. Penelitian memakai pendekatan deskriptif-kuantitatif dan dilaksanakan di Laboratorium Biologi FMIPA UNP pada Agustus–November 2025. Isolat pseudomonas berfluoresen dan R. solanacearum diremajakan pada media selektif, kemudian diuji antagonismenya menggunakan metode swab pada medium MHA. Suspensi patogen distandarkan pada McFarland 0,5, sedangkan isolat antagonis diinokulasikan secara titik. Zona hambat yang terbentuk setelah inkubasi 24 jam diukur menggunakan jangka sorong dan dianalisis secara deskriptif. Hasil penelitian menunjukkan adanya variasi kemampuan penghambatan antar isolat. Pada patogen tomat, isolat PfB305, PfB309, PfB311, dan PfB322 menghasilkan zona hambat yang relatif besar, sedangkan PfB32, PfB51, dan PfB52 tidak menunjukkan aktivitas antagonis. Pada patogen nilam, tiga isolat yang sebelumnya tidak aktif pada patogen tomat justru menghasilkan zona hambat, sementara empat isolat lainnya tidak membentuk zona hambat. Penelitian ini menunjukkan bahwa efektivitas pseudomonas berfluoresen dipengaruhi oleh spesifisitas isolat terhadap patogen serta potensi produksi metabolit antibakteri

Abstract

Cumi-cumi (Loligo sp.) dan Sotong (Sepia sp.) adalah komoditas perikanan bernilai tinggi di Indonesia, dikenal karena kandungan protein dan rasanya yang lezat. Penyimpanan yang tidak tepat dapat mempercepat pertumbuhan bakteri pembusuk, menurunkan kualitas produk dan membahayakan kesehatan konsumen. Penelitian ini bertujuan untuk mengidentifikasi pengaruh lama penyimpanan terhadap pertumbuhan bakteri pada daging Cumi-cumi (Loligo sp.) dan Sotong (Sepia sp.). Metode penelitian yang digunakan adalah eksperimen. Sampel daging cumi-cumi dan sotong diberikan perlakuan penyimpanan pada suhu ruang dan suhu kulkas selama 2, 4, dan 6 jam dan kontrol yaitu sampel yang tidak diberi perlakuan. Hasil penelitian menunjukkan bahwa suhu dan lama penyimpanan berpengaruh signifikan terhadap pertumbuhan bakteri. Pada suhu ruang, jumlah bakteri pada Cumi-cumi dan Sotong meningkat tajam setelah 6 jam penyimpanan. Penyimpanan pada suhu dingin atau kulkas pada lama penyimpanan 6 jam pada Cumi-cumi dan Sotong mengalami peningkatan jumlah bakteri walaupun tidak terlalu signifikan, hal ini terjadi karena pada suhu dingin terdapat bakteri psikrofilik yang mampu bertahan pada suhu dingin.
