Kappaphycus alvarezii merupakan  salah satu spesies makro alga yang paling banyak dibudidayakan di Indonesia. Penyakit utama yang menyerang budidaya rumput laut ini adalah penyakit ice-ice  yang  dapat menurunkan hasil panen hingga 70-80%.  Tujuan penelitian iniadalah  untuk mengetahui bakteri patogen yang berasosiasi dengan K. alvarezii bergejala penyakit ice-ice dan mengetahui agen penyebab penyakit ice-ice. Jenis penelitian yang dilakukan adalah penelitian deskriptif. Sampel K. alvarezii yang bergejala ice-ice diambil dari lokasi budidaya di Teluk Bumbang Dusun Gerupuk Lombok Tengah. Sampel tersebut kemudian dibawa ke Laboratorium Biologi untuk diisolasi bakteri yang berasosiasi dengan K. alvarezii bergejala ice-ice. Terhadap isolat yang diperoleh dilakukan karakterisasi parsial. Selanjutnya dilakukan uji patogenisitas (postulat Koch) untuk mengetahui apakah bakteri yang diperoleh merupakan agen penyebab penyakit ice-ice. Hasil isolasi menunjukkan terdapat 28 isolat bakteri yang berasosiasi dengan K. alvarezii bergejala ice-ice. Selanjutnya, uji postulat Koch memperlihatkan hanya satu isolat yang mampu menyebabkan gejala ice-ice yaitu isolat K25Kata Kunci : Kappaphycus alvarezii, penyakit ice-ice, postulat Koch

Faturrahman, Meryandini A, Junior MZ, Rusmana I (2011) Isolation and identification of an agar-liquefying marine bacterium and some properties of its extracellular agarases. Biodiversitas 12: 192-197. A new agar-liquefying bacterium, designated Alg3.1, was isolated from Gracilaria samples collected from the Kuta Coast at Central Lombok in West Nusa Tenggara and was identified as Aeromonas sp. on the basis of morphology, biochemical-physiological character and 16S rDNA gene sequencing. The bacterium appeared capable of liquefying agar in nutrient agar-plate within 48 hours of incubation and the agar was completely liquefied after l5 days at 29 o C. When the isolate was grown in basal salts solution medium B supplemented with peptone and yeast extract, produced extracellular agarases within a short period of time (4-16 h) and the maximum agarase activity was 0.489 nkat/mL at 36h after incubation.

Objective: To present a casereport of a 20 years old male with Le Fort II fracture accompanied with blowout fracture and its management. Methods: A 20 years old male patient with chief complaint of maxillary fracture and inability to chew food, also felt limitation of right eye movement and double vision was then diagnosed with Le Fort II fracture accompanied with blowout fracture of the right orbital base. The patient was rehabilitated using open reduction internal fixation of the maxilla to achieve good occlusion continue with immobilization. The orbital base fracture was rehabilitated by orbital mesh placement and release of tissue trapped inside the orbital base fracture fragments to achieve normal position and movement of the eyeball. Results: One month post-surgery follow-up showed the face was symmetrical and the enophthalmos was corrected. A good occlusion was reached. Conclusion: Proper management of Le Fort II fracture accompanied with orbital base blowout fracture can restore the function of the eye, mastication and occlusion. Symmetrical and proportional facial esthetics are among the indicators of a successful holistic maxillofacial trauma management.

This research aimed to study the growth responses of maize and soybean to the indigenous bacterial consortium application isolated from Lombok dryland farm. The study was  tested  in the sterile soil and nonsterile soil of growing media and with a different water capacity of growing media. The soil was taken from North Lombok dryland farm. Sterile soil was prepared by sterilization using an autoclave. The bacterial consortium was prepared by mixing 15 inoculums of rhizosphere bacteria isolated from Lombok dryland farm. The consortium inoculation by soil inoculation technique. The water capacity of growing media was set to 25%, 50%, and 75%. This research was done in the greenhouse scale. Growth parameters that  analyzed were leaf number, leaf wide, leaf length, plant length, fresh weight of upper biomass, and dry weight of upper biomass. The results showed that plant growth is better in  sterile soil  compared to nonsterile soil. Plant growth is better also in the sterile soil inoculated with the bacterial consortium compared to nonsterile soil inoculated with the bacterial consortium. Plant growth was better in 75% and 50% than 25% water holding capacity of growing   Keyword: bacterial consortium, dryland farm, rhizosphere, North Lombok
