Judul: Pendugaan Produktivitas Serasah Zona Montana di Hutan Hujan Pegunungan Di Gunung Gede, Jawa Barat
Abstrak: Hutan hujan pegunungan merupakan salah satu bentuk formasi hutan tropika Indonesia yang memiliki berbagai fungsi dan sudah selayaknya dapat dimanfaatkan secara optimal oleh manusia. Hutan ini sebagian besar terletak pada ketinggian ]500 sampai 2700 meter dari muka laut. Taman Nasional Gunung Gede-Pangrango merupakan salah satu wakil dari ekosistem hutan hujan pegunungan di Propinsi Jawa Barat dan dikenal sebagai tempat tumbuh flora-fauna hutan hujan tropis pegunungan yang kaya akan jenis. Gunung Gede memiliki potensi dan fungsi antara lain untuk fungsi perlindungan dan pelestarian, fungsi pendidikan, pengetahuan dan kebudayaan, serta fungsi rekreasi dan pariwisata.

Judul: Bioelectricity Production from Citrobacter freundii GBH253 and Chlorella pyrenoidosa on Microbial Fuel Cell Anode with Different Carbon Sources
Abstrak: Microbial Fuel Cell (MFC) development has significantly increased from various aspects to get higher and more stable electricity. Developing MFC on microorganism aspect is very important because it plays a crucial role in the MFC system. C. freundii GBH253 is one of the potential exoelectrogen bacterium that could be developed for the MFC system. Integrating C. freundii GBH253 and electricity-producing microalgae, such as C. pyrenoidosa, in the anode of MFC could get more stable and higher electricity. In this study, C. freundii GBH253 and C. pyrenoidosa were coupled to produce electricity from different substrates. C. freundii GBH253 and C. pyrenoidosa were tested on three different media types before being tested on MFC. They were also examined for the co-cultivation test to determine the symbiotic relationship between the two microorganisms. The MFC test was conducted using the Randomized Block Design Factorial and the Tukey test to see significant differences from each treatment. The parameters observed in this study were voltage, power density, Chemical Oxygen Demand (COD), Coulombic Efficiency (CE), pH, and volatile fatty acid (VFA). C. freundii GBH253 cannot grow on microalgae medium, while C. pyrenoidosa could grow on bacterial medium and a mixture of bacterium and microalgae media. The bacterium gained benefit from co-culture with microalgae. In the MFC test, electricity was generated in all treatments, which bacterium + microalgae with acetate treatment could generate power density up to 211,97 mW/m2 and the most stable compared to others. Production of electricity in bacterium-microalgae combination dominated by the bacterium; hence, microalgae still help bacterium by producing electricity and raised the COD value. The pH value of all treatments was higher than the initial pH. Acetate and phenol were VFA produced in all treatments, whereas butyric acid and propionic acid were found in some treatments. Pearson correlation showed that some VFA highly correlated with power density.
