Abstract

This study aims to investigate the bioelectricity production pattern of a thermophilic bacterial consortium from Sapan Sungai Aro. Thermophilic bacteria, which can survive at high temperatures, have the potential to generate electricity through their metabolic activity. In this study, the thermophilic bacterial consortium was isolated from Sapan Sungai Aro and tested for bioelectricity production at a 5% concentration with various consortium ratios (1:2, 2:1, 1:3, 3:1). The data show that the stationary phase at the 20th hour produced the highest voltage, which was 0.764 V, at the 3:1 ratio. These results indicate that the optimal composition of the bacterial consortium influences the efficiency of bioelectricity production. Moreover, this study also reveals that both the exponential and stationary phases play important roles in electricity generation, with the stationary phase providing the most ideal metabolic conditions

Abstract

Kuman patogen yang resisten terhadap antimikroba merupakan masalah global. Terjadinya patogen yang resisten mengakibatkan infeksi lebih sulit untuk diobati, dan berujung pada meningkatnya angka kematian. Untuk mengatasi masalah resistensi antimikroba, perlu dicari sumber-sumber senyawa aktif baru salah satunya menggunakan tumbuhan obat. Salah satu tumbuhan obat yang berpotensinya khususnya sebagai antikanker, antibakteri dan antifungi adalah Cemara sumatra (Taxus sumatrana) yang mengandung senyawa aktif taxol, flavonoid, fenolik dan lignan. Penelitian ini bertujuan untuk mengisolasi dan menguji aktivitas antimikroba cendawan daun Taxus sumatrana. Untuk memperoleh senyawa aktif maka dilakukan isolasi mikroba. Cendawan yang telah diisolasi diidentifikasi berdasarkan morfologinya. Isolat cendawan endofit difermentasi untuk mendapatkan produk metabolit sekunder dan diuji aktivitas antimikrobanya. Penelitian ini berhasil mengisolasi 9 jenis isolat cendawan endofit dari daun Taxus sumatrana. Pada bakteri S. aureus diperoleh diameter sebesar 14 mm oleh isolat TD3. Pada bakteri E. coli, aktivitas antimikroba yang paling kuat dihasilkan oleh isolat K1 sebesar 8.50 mm, selanjutnya aktivitas antimikroba yang paling tinggi terhadap C. albicans dihasilkan oleh isolat D6 sebesar 9.93 mm. Aktivitas antimikroba yang paling baik dihasilkan oleh isolat TD3 terhadap S. aureus.

Abstract

Research aim : This study examines the moderating role of investor risk behavior in the relationship between financial literacy and investment decisions among millennials. Design/Methode/Approach : A quantitative approach was employed, collecting data from 96 millennial investors through a structured survey. Structural Equation Modeling-Partial Least Squares (SEM-PLS) was utilized to analyze both direct and indirect relationships among variables. Research Finding : The findings indicate that financial literacy does not significantly influence investment decisions. However, financial literacy has a positive and significant impact on investor risk behavior, which, in turn, significantly influences investment decisions. Furthermore, investor risk behavior moderates the relationship between financial literacy and investment decisions in a positive and significant manner. Theoretical contribution/Originality : These results highlight the critical role of risk behavior as both a mediating and moderating mechanism in leveraging financial literacy for improved investment decision-making. Practitioner/Policy implication : The study's practical implications suggest that financial literacy programs should not only focus on enhancing knowledge but also on fostering risk management skills to support informed investment choices. Research limitation : This study is limited by its relatively small sample size and geographic focus on Makassar City, which may restrict the generalizability of the findings to broader populations. Additionally, the cross-sectional design captures only a snapshot of behavior, making it difficult to infer long-term patterns or causal relationships.

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

The increasing demand for electricity has triggered the development of environmentally friendly alternative energy sources. One promising innovative technology is the Microbial Fuel Cell (MFC), which utilizes electroactive microorganisms such as exoelectrogens to generate electricity from organic materials. This research aims to analyze the impact of organic fertilizer soil and the addition of water on bi-electricity production in MFC systems. The experiment was conducted using organic fertilizer soil as a substrate, with parameters such as voltage and power density being measured regularly. The results show that exoelectrogenic microbes can significantly enhance electricity production, with specific treatments (P2 U1) providing the highest stability in electricity generation over 24 hours. The addition of water also positively impacted microbial activity and electron transfer. This study reinforces the potential of organic fertilizer soil-based MFCs as a sustainable and environmentally friendly renewable energy source.

Keamanan pangan sangat penting untuk melindungi kesehatan masyarakat, khususnya untuk produk pangan yang rentan terhadap kontaminasi mikroba. Kunyit bubuk curah yang dijual di pasar tradisional berisiko terkontaminasi jamur karena praktik penanganan yang tidak higienis, yang dapat mengurangi kualitas produk dan menimbulkan bahaya kesehatan. Penelitian ini bertujuan untuk mengetahui tingkat kontaminasi jamur pada kunyit bubuk curah yang dijual di Pasar Lubuk Buaya, Kota Padang, dan untuk mengidentifikasi karakteristik makroskopis jamur yang tumbuh. Penelitian ini dilakukan dari Oktober 2025 hingga Januari 2026 di Laboratorium Mikrobiologi, Departemen Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Padang. Desain penelitian deskriptif digunakan dengan metode pengambilan sampel purposif. Sampel kunyit bubuk curah dipilih dan dikumpulkan dari lima pedagang dengan tingkat kebersihan yang berbeda. Kontaminasi jamur dinilai menggunakan metode penghitungan kapang dan ragi (MYC) dengan teknik spread plate pada media Potato Dextrose Agar (PDA), diikuti dengan pengamatan makroskopis morfologi koloni jamur. Hasil menunjukkan bahwa semua sampel kunyit bubuk curah terkontaminasi jamur, dengan tingkat kontaminasi berkisar antara 2,67 × 10⁵ hingga 2,9 × 10⁶ CFU/g. Semua sampel melebihi batas maksimum yang diizinkan untuk kontaminasi mikroba sebagaimana ditetapkan oleh Badan Pengawas Obat dan Makanan Indonesia (BPOM). Jamur kontaminan yang diidentifikasi meliputi Aspergillus flavus, A. niger, Penicillium sp., dan ragi. Oleh karena itu, dapat disimpulkan bahwa kunyit bubuk curah yang dijual di Pasar Lubuk Buaya, Kota Padang, tidak memenuhi standar keamanan pangan mikrobiologis.
