Abstract

The increasing energy demand encourages the development of renewable energy technologies such as Microbial Fuel Cell (MFC), which converts organic substrates into electricity using microorganisms. This study aimed to analyze bioelectricity production by Aneurinibacillus thermoaerophilus strain N25 using different substrates (glucose, corn cob, rice straw, and rice husk). The experiment was conducted using a dual-chamber MFC system with voltage measurements over 24 hours. The results showed that voltage increased over time, peaked at the 20th hour, and then decreased. The highest voltage was produced by glucose (0.802 mV), followed by corn cob (0.724 mV), rice straw (0.581 mV), and rice husk (0.491 mV). These results indicate that substrate type affects bioelectricity production, with corn cob as the best agricultural waste substrate.

Abstract

Kebutuhan energi listrik yang terus meningkat mendorong pengembangan sumber energi alternatif, salah satunya melalui teknologi Microbial Fuel Cell (MFC). Penelitian ini bertujuan untuk mengkaji kemampuan produksi energi listrik oleh bakteri termofilik Bacillus licheniformis strain NA14 dari sumber air panas Mudiak Sapan serta pengaplikasiannya dalam menyalakan lampu LED sebagai indikator biolistrik. Penelitian ini bersifat deskriptif dan dilakukan di Laboratorium Mikrobiologi FMIPA Universitas Negeri Padang pada Oktober 2025 hingga Februari 2026. Sistem MFC yang digunakan berupa bioreaktor dual - chamber dengan rangkaian seri tiga menggunakan elektroda zink sebagai anoda dan tembaga sebagai katoda, serta jembatan garam sebagai penghubung. Medium yang digunakan adalah Broth Thermophilic Medium (BTM) yang diinokulasikan dengan isolat bakteri termofilik. Hasil penelitian menunjukkan bahwa sistem MFC mampu menghasilkan tegangan sebesar 2,60 V sehingga dapat menyalakan lampu LED. Intensitas nyala LED dipengaruhi oleh aktivitas elektrogenik bakteri dalam mengoksidasi senyawa organik dan mentransfer elektron ke anoda. Selain itu, aktivitas enzimatik seperti xilanase serta pola pertumbuhan bakteri pada fase eksponensial dan stasioner turut mendukung peningkatan produksi listrik. Dengan demikian, Bacillus licheniformis strain NA14 berpotensi sebagai bioelectricigens dalam pengembangan teknologi MFC sebagai sumber energi alternatif.

Abstract

Rice (Oryza sativa L.) plays a crucial role as a primary food source in Indonesia, and efforts to improve its growth need to be directed toward sustainable cultivation systems. The use of soil microorganisms, such as Effective Microorganisms-4 (EM4) and Trichoderma sp., is a widely studied alternative due to its ability to improve the condition of other microorganisms obtained from the soil around the roots and support plant growth. This study was conducted to determine the effect of a combination of EM4 and Trichoderma sp. on the vegetative growth of rice plants. The study was conducted from December to February 2026 in Pagambiran Ampalu Village, Lubuk Begalung District, using a completely randomized design (CRD) with six treatments and four replications. Observed parameters included plant height, number of leaves, number of tillers, and plant dry weight. Data were analyzed using analysis of variance (ANOVA) followed by Duncan's test at a 5% significance level. The results showed that the combination of EM4 and Trichoderma sp. improved several

Abstract

The diversity of shade tree on campus plays an important role in supporting ecological, aesthetic, and educational functions of the environment. This study aimed to identify the species, number of individuals, and potential uses of tree-like plants at Padang State University campus. The study was conducted in December 2025 using survey and direct field observation methods with a qualitative descriptive approach. Species identification was based on plant morphological characteristics with the assistance of literature and plant identification applications. The results showed 1.544 tree individuals belonging to 26 species from 17 families. The most dominant species was Leucaena leucocephala, followed by Pterocarpus indicus, Terminalia catappa, Terminalia mantaly, and Veitchia merillii. The high diversity was influenced by habitat heterogeneity, tropical climate conditions, and variations in soil physical and chemical properties. The presence of tree vegetation contributes to improved air quality, microclimate regulation, CO₂ absorption, and habitat provision for other organisms. The UNP campus area has a high diversity of tree-like plants and plays an important role in supporting the sustainable management of campus green open spaces.

Abstract

Plant diversity plays an important role in maintaining environmental balance, particularly in urban areas. Universitas Negeri Padang has considerable potential for plant diversity, especially within the monocotyledonous plant group (Monocotyledonae). This study aimed to identify and describe the diversity of monocot plant species in the campus environment based on their morphological characteristics. The research employed a descriptive method through field observations by recording morphological traits, including growth habit, stem, leaves, and reproductive organs. Species identification was carried out using botanical literature and taxonomic references, while data were analyzed descriptively based on taxonomic levels. The results showed that 24 species of monocot plants were identified, belonging to 12 families and 5 orders, namely Arecales, Asparagales, Poales, Zingiberales, and Alismatales. The dominant families included Arecaceae, Araceae, Asparagaceae, and Poaceae. The identified species exhibited morphological variations in leaf structure, stem, root system, and reproductive organs. This diversity reflects the relationship between morphological characteristics and environmental conditions, and also provides educational value as a learning resource in plant morphology and taxonomy studies.

Abstract

Salinity is one of the major limiting factors in rice cultivation, negatively affecting seed germination and early plant growth. One approach that can be taken to improve seed tolerance under saline conditions is seed priming. This study aims to examine the effect of potassium nitrate (KNO3) seed priming on the germination and early growth of IR 64 rice seeds at various salinity levels. This study was an experiment designed using a completely randomized design with a single treatment factor, namely NaCl salinity levels (0, 50, 100, and 150 mM), in which all seeds were treated with 1% KNO3 seed priming prior to stress application. Each treatment was replicated four times. The observed parameters included germination percentage, root length, shoot length, seedling length, and seed vigor index. The data were analyzed using analysis of variance (ANOVA) followed by Duncan’s multiple range test at a 5% significance level. The results showed that KNO3 seed priming was able to maintain the germination percentage of IR 64 seeds at all salinity levels, with values that were not statistically significantly different. However, increasing NaCl concentrations had a significant negative effect on the morphological growth of seedlings, as indicated by a decrease in root length, shoot length, seedling length, and seed vigor index. The treatment without salinity produced the best early growth, while high salinity significantly inhibited seedling growth. Based on these results, it can be concluded that KNO3 seed priming plays an effective role in maintaining the viability of IR 64 rice seeds under saline conditions, but it is not yet fully capable of overcoming the negative effects of salinity on early plant growth.

Abstract

Coronavirus merupakan virus RNA untai tunggal positif yang memiliki keragaman genetik tinggi dan mampu berevolusi melalui mutasi serta rekombinasi. Kelelawar diketahui sebagai reservoir alami coronavirus karena memiliki sistem imun yang unik serta karakteristik ekologi yang mendukung penyebaran virus. Penelitian ini bertujuan untuk menganalisis dan mensintesis berbagai hasil penelitian mengenai karakteristik dan distribusi coronavirus pada kelelawar. Metode yang digunakan adalah literature review dengan mengumpulkan artikel dari Google Scholar, PubMed, dan ScienceDirect dalam sepuluh tahun terakhir. Hasil kajian menunjukkan bahwa coronavirus pada kelelawar memiliki keragaman genetik yang tinggi, terutama pada kelompok Alphacoronavirus dan Betacoronavirus, serta tersebar luas di berbagai wilayah, khususnya Asia Tenggara. Beberapa penelitian juga menunjukkan adanya potensi transmisi lintas spesies (spillover) yang dipengaruhi oleh adaptasi virus dan faktor lingkungan. Kesimpulannya, kelelawar berperan penting dalam menjaga keragaman dan distribusi coronavirus, sehingga diperlukan pemantauan yang berkelanjutan untuk mencegah munculnya penyakit zoonotik di masa depan.
