The depletion of fossil fuel reserves requires advance anticipation through the search for alternative energy from renewable natural resources. Microalgae have been known as potential organisms biodiesel feedstock. However, in order to be developed on a large scale, microalgae must superior traits so that further development becomes more comfortable and cheaper. Tropical lakes are source adapted moderate conditions which can later save operational costs large-scale production. Situ Gintung...
Abstract Microplastics are contaminants in the form of tiny plastic fragments diluted terrestrial and aquatic environments. Recently, these have become a concern due to their negative impact on quality life living things. The isolation examination microplastic degrading microorganisms' ability from two large mature landfills were conducted. Therefore, this study aims obtain bacteria fungi as bioremediation agents that can degrade microplastics. process was conducted by direct indirect...
Elephant dung is a source of methane gas, which the gas main contributor to greenhouse if not used as fuel.Wild elephants use grass leaves their feed, but in Ragunan Wildlife Park, are fed also with combination elephant grass, sweet potatoes, maize, and bananas, aim meet immediate nutritional needs ensure health.Therefore, this study examined biogas production feces associated feed given.The purpose investigate contribution that emitted from result two kinds were bananas.Previously,...
The contamination of aquatic environments with heavy metals poses a serious threat to fish, potentially leading diseases or even death. Therefore, there is an urgent need for studies investigate the adaptability fish in metal-contaminated environments. Several have explored suckermouth catfish (P. pardalis) survive contaminated Ciliwung River. findings obtained showed that presence intestinal bacteria helped these overcome their intestines, thereby enabling survive. Analysis using Next...
The water quality in the interim wet storage of spent fuel (ISSF) needs to be monitored due its function as a radiation shield. Water ISSF pools must free from microorganisms such microalgae that live radioactive environment. Moreover, particular are capable causing corrosion stainless steel, which is component ISSF. Therefore, this study aims determine diversity and those living environment, cause corrosion. were detected using Palmer indices. sampling was carried out by vertical filtration...
Nutrien daun kelor (Moringa oleifera) dan jerami kacang hijau (Vigna radiata) sebagai hijauan pakan ternak cukup berkualitas sehingga perlu diproteksi untuk meningkatkan efektivitas penggunaannya di dalam rumen. Daun nangka mengandung total tanin sebesar 7,08%, potensial digunakansebagai bahan memproteksi sumber protein. Studi in vitro dilakukan mengevaluasi penggunaan tepung berupa hijau. Tujuan dari studi yang adalah mengetahuipengaruh penambahan terhadap nilai biologis Evaluasi produksi...
The airborne bacteria and fungi in parking building, playground food court Blok M Square, South Jakarta, were assessed order to investigate air quality one of the shopping center Jakarta. sample was passed through plate count agar potato dextrose using a single-stage multi-orifice Sampler SKC Biostage Standard. Results showed that average microbial concen-trations 200.17, 101.17, 55, 33 CFU per m 3 , 109.54, 37.69, 27.09 volume children court, respectively. most dominating had...
Gas metana dari ternak ruminansia merupakan salah satu penyumbang emisi gas rumah kaca terbesar di dunia, termasuk Indonesia. yang bersumber peternakan berasal dua sumber emisi, yaitu pencernaan dan feses, sehingga produksinya dapat dikurangi melalui modifikasi pakan. Salah strategi untuk mengurangi produksi tersebut adalah dengan penambahan bakteri denitrifikasi, mengalihkan akseptor elektron metanogenesis kepada denitrifikasi. Penelitian ini bertujuan menyelidiki potensi denitrifikasi...
Studies that explore the diversity of microorganisms in unusual (extreme) environments have become more common. Our research aims to predict bacteria inhabit an extreme environment, a coal mine’s soil with pH 2.93. Soil samples were collected from at depth 12 meters surface, which is clay layer adjacent seam Tanjung Enim, South Sumatera, Indonesia. A culture-independent method, polymerase chain reaction based denaturing gradient gel electrophoresis, was used amplify 16S rRNA gene detect...
Abstract. Sugoro I, Fadila DSR, Pikoli MR, Hermanto FE, Ramadhan F, Shalsabilla SE, Cici A, Rijal MS, Rahayu DS, Puspito MJ, Haribowo DR, Tetriana D. 2023. Amplicon-based sequencing revealed potential microbiologically influenced corrosion in the interim storage for spent fuel of RSG-GAS, Serpong, Indonesia. Biodiversitas 24: 5391-5398. Interim (ISSF) can negatively impact nuclear power plant maintenance, specifically concerning safety, financial costs, and regulatory compliance. Besides...
The water quality of the gamma irradiator pond must be adequate, such as no corrosion-causing bacteria are detected. Corrosion events a significant concern because they affect durability facilities. This study aims to determine sulfate-reducing (SRB) that cause corrosion on surface pool wall from natural rubber (IRKA) made metal. Sampling was carried out at 5 points, with research stages consisting sampling (pool swabs and walls), qualitative SRB tests, bacterial DNA isolation. results...
Gyrinops versteegii is one of the agarwood-producing plants containing various compounds that are useful in pharmaceutical and cosmetic industries. The exploitation agarwood threatens existence this plant can be prevented through an artificial induction formation using fungal inoculants. This study aimed to determine volume frequency inoculation a mixture fungi SP1 SP2 which was most suitable for inducing G. Cijeruk, Bogor. method research consisted preparation enrichment medium, cultivation...
Tapioka dapat digunakan sebagai medium pertumbuhan isolat khamir karena mengandung karbohidrat tinggi. Sterilisasi dengan iradiasi sinar gamma menghasilkan senyawa yang lebih sederhana dan bersifat toksik. Tujuan dari percobaan ini adalah untuk mengetahui pengaruh dosis terhadap sifat fisik kimia serta R1 R2 mutan R110 R210. Dosis 10, 20, 30 kGy. Hasil menunjukkan bahwa terjadi perubahan warna semakin gelap granula pati kecil sebanding meningkatnya dosis, sedangkan secara penurunan pH...
The adaptability of Suckermouth Catfish (Pterygoplichthys pardalis) to survive in the contaminated Ciliwung River can be supported by presence microbiota intestinal, specifically bacteria. Furthermore, intestinal bacteria facilitate nutrient absorption, immunity, gastrointestinal development, homeostasis, and xenobiotic metabolism fish. Analysis using Next Generation Sequencing (NGS) technology has succeeded identifying diversity these P. pardalis living River. index was relatively high....
Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria release covalently-bound from the matrix. Coal is a complex hydrocarbon material that requires collaboration more than one type of consortium for desulfurization. The current study shows how individual members bacterial obtained directly samples grew on coal. Mineral medium containing sub-bituminous with concentration 10%, 15%, and 20% served as carbon source only support...
Bacteria capable of desulfurization organic substances in coal and petroleum are required to improve the quality fuel.We have thus isolated bacteria from sources examined their growth activities monocultures.Three viable strains were obtained using two procedures: one-step enrichment gradual enrichment.A medium was used which enriched with dibenzothiophene, most dominant sulfur coal.Based on analysis 16S rRNA gene, it found that closely related Moraxella osloensis, Pseudomonas aeruginosa,...
Lignite coal was found abundant in Indonesia, but usage for this type of still relatively low. Economic value increases when it is solubilized.
