Abstract

Tanaman Indonesia bervariasi sehingga kita sebaiknya mengeksplorasi manfaat dari tanaman tersebut. Rumput belulang (Eulisine indica) merupakan tanaman gulma yang dianggap masyarakat tidak ada manfaatnya. Daun mengkudu (Morinda citrifolia) belum banyak pemanfaatannya karena biasanya pada tanaman mengkudu yang dimanfaatkan buahnya. Masyarakat di Indonesia pada umumnya memanfaatkan tanaman yang berkhasiat obat dengan cara merebus tanaman dengan air kemudian dikonsumsi. Berdasarkan Farmakope Indonesia Edisi III, infusa merupakan proses ekstraksi tanaman dengan menggunakan pelarut air kemudian dipanaskan dalam panci infusa pada suhu 90oC selama 15 menit. Tujuan penelitian untuk memanfaatkan infusa Eulisine indica dan daun Morinda citrifolia dengan melakukan uji aktivitas antibakteri pada bakteri gram positif Staphylococcus aureus menggunakan metode difusi. Penelitian ini juga bertujuan untuk mengidentifikasi secara kualitatif senyawa bioaktif pada infusa Eulisine indica dan daun Morinda citrifolia. Hasil uji aktivitas antibakteri menunjukkan tidak terdapat zona hambat pada ekstrak Eulisine indica dan daun Morinda citrifolia. Identifikasi senyawa bioaktif dari Eulisine indica dan daun Morinda citrifolia menunjukkan hasil positif terhadap adanya kandungan antrakuinon dengan menunjukkan warna kuning dan menunjukkan hasil negatif terhadap alkaloid, flavonoid, steroid atau terpenoid setelah diujikan dengan beberapa pereaksi kimia. Berdasarkan penelitian Dhiman, A et.al (2011), pemanfaatan senyawa bioaktif sebagai antibakteri dari tanaman yaitu adanya kandungan flavonoid, steroid dan tannin.

Abstract

Sumatera is one of the largest mangrove areas in Indonesia. One of the mangrove plants that have the potential as a drug and has been used traditionally is Xylocarpus granatum. This study was conducted to determine the influence of methanol extract from leaf X. granatum in inhibiting the growth of Staphylococcus epidermidis. Extraction of leaf X. granatum is done by the maceration method using methanol solvent. Test resistance of methanol extracts from the leaves of X. granatum is performed by a method of diffusion discs. Measurement of antibacterial activity is carried out with several treatments i.e. the negative control (aquadest), positive control (Chloramphenicol), and several different extract concentrations of 25ppm, 50ppm, 75ppm, and 100ppm. The value of the antibacterial activity is then analyzed further using ANOVA and the Dunn test. The results showed that the leaves extract X. granatum extracted using a methanol solvent contained active phytochemicals compounds such as steroids, saponins, tannins, and phenols. The test results of each extract concentration showed a significant influence on the slow growth of S. epidermidis, characterized by the formation of a clear zone around the disc. The highest antibacterial activity is shown at a concentration of 25ppm with an antimicrobial index value of 3,55 which is categorized as a strong antibacterial response.

Abstract

Lake Teluk natural potential is very rich in zooplankton. However, the there are many untapped potential, so that appropriate unknown environmental factors to support the growth, reproduction, and abundance of zooplankton that is potential as fish food can be cultivated properly. Therefore, there needs to be research related to environmental factors and abundance of zooplankton in Lake Teluk Jambi city in order to see the natural potential of fish forage in the area. This study was conducted at three stations in the Lake Teluk Jambi and Biotechnology Laboratory, Faculty of Science and Technology, the Jambi University. The method used in this research was the survery and analysis. Measured parameters were factors abundance of zooplankton and the physical and chemical environmental factors. The identification results obtained three phyla of zooplankton (protozoa, rotifers and sponges) and 14 genuses that were Platytrichotus, Centropyxis,Perispira, Corythion, Acropisthium, Turania, Trinema, Euglypha, Enteroplea, Proalinopsis, Pedipartia, Trocospheera, Filinia, Meyenia. Analysis of physical and chemical environmental factors showed solubility values (DO) range 4,8 - 6,8 mg/L, the water temperature ranges from 29-30 °C and oxygen consumption (BOD) in the range of 3,7 to 6,6 mg/L relatively optimal for the growth of zooplankton, but have not found any zooplankton that have the potential to be cultivated as a natural fish feed.

Abstract

Rice (Oryza sativa) is a major crop product in Asia. Rice products are increasing along with the increasing of human population. Blast disease in leaf (leaf blast) is the major pathogen in rice during vegetative phase. The using of amylolytic bacteria isolated from Geopark Merangin Jambi is done as an attempt to discover biocontrol agents in order to attack infection of Pyricularia oryzae, the cause of leaf blast disease. Antimicrobial activity assay was carried out by isolating the pathogen in the infected rice crops. Pyricularia oryzae that had been cultured then were evaluated their antagonistic activity against amylolytic bacteria isolated from prior experiment. Results have shown that from 25 isolates of amylolytic bacteria taken from Geopark Merangin Jambi, 2 isolates that can be used as biocontrol agents were GM20 and GM23 capable of inhibiting the growth of Pyricularia oryzae.

Abstract

The mangrove ecosystem is a coastal wetland resource that has a diversity of biodiversities such as flora, fauna, and microorganisms. Microbes are an important component in the mangrove environment not only play a role in creating and maintaining boosters but also work as a source of biotechnology products. Cellulolytic bacteria are a group of cellulase-producing bacteria capable of breaking down cellulose into glucose monomers, and cellulose as a source of carbon and energy. This study aims to screen and determine the diversity of cellulolytic bacteria from the mangrove ecosystem. The research method was experimentally by exploring the diversity of cellulolytic bacteria from soil and sediment from the mangrove ecosystem. Three sampling locations were selected, such as litter soil, soil in the root area, and soil in the tidal area. Screening of potential bacteria producing cellulase enzymes was carried out by growing bacteria on Carboxy Methyl Cellulose (CMC) agar medium which was cultured for 48 hours at 37°C. The bacteria that produced the greatest cellulolytic activity were characterized by their morphological and physiological characteristics. The results of bacterial characterization were then adjusted according to Bergey's Manual of Determinative Bacteriology. Based on the analysis showed three bacterial isolates were obtained that had the largest cellulolytic activity index, namely MS06 (9.73), MS08 (5.41), and MS02 (5.07). The results showed that three isolates had the same characteristics as the bacterial genera Bacillus, Cellulomonas, and Micrococcus.
