The number of bacterial isolates obtained from the lobster pearl digestive tract were 51 isolates with details of 18 cardiac isolates, 16 isolates in piloric, and 17 isolates in the intestine. Phenotypic isolates obtained from lobster digestive tract bacteria consisted of monococcus 37.25%, diplococcus 27.45%, streptococcus 29.41%, staphylococcus 1.96%, and long baccil 3.92%, while gram positive 62.65 % and gram negative at 37.25
Identifikasi Sifat, Ciri, dan Jenis Tanah Utama di Pulau Lombok
Get PDFTA descriptive research aimed to identify the characteristics and name of main soils in Lombok Island was carried out through field observation for soil profiles and landform and laboratory analyses for soil physical and chemical properties. The type or name of soil was defined by using The National (Indonesian) Soil Classification System (2014), Soil Taxonomy (SSS-USDA, 2014), and World Soil Reference (FAO, 2014). There were 4 main types of soil in Lombok Island, which were Litosol, Aluvial, Kambisol, and Vertisol; and a fairly developed soil in limited spots was Mediteran. Based on the soil taxonomy system, those soils were respectively equivalent to Orthents, Fluvents, Undepts, Underts, and Udalfs; whereas based on the soil system of FAO, were Leptisols, Fluvisols, Cambisols, Vertisols, and Luvisols. The main characteristics of Litosol/Orthents/Leptosols Lombok were shallow solum (< 25 cm on the rocks or lithic contacts), coarse textured (sandy), nutritionally deficient, very low CEC (< 5 cmolc.kg-) and C-organic content (< 1 %). Aluvial or Fluvents, were mainly utilized as paddy soil, consisting of several layers which it clay and C-organic content were changed irregularly with depth, CEC of top soil (Ap) was medium (5–10 cmolc.kg-), and it was relatively fertile. Kambisols or Undepts was fairly deep (consisting of 40 – 60 cm of A and B horizons,), loamy textured, fairly fertile, CEC was medium, and C-organic content was low – medium (1–2 %). Vertisol or Uderts was characterized by a significant swell-shrinking properties, clay textured, extremely hard to be cultivated, high CEC, Ca, and Mg, and relatively fertile soil. Mediteran or Udalf was a further developed soil (solum > 100 cm), clay translocation has been occurred from upper (E) to lower horizons (Bt), CEC was fair, and it was relatively fertile soil. In conclusion, the pedologic development of soils in Lombok Island was relatively slow due mainly to the low–moderate rainfall, and the soil types were dominated by Litosols, Aluvials, Kambisols, and Vertisols, and Mediteran in small area. In order to provide a complete reference for the characteristics of main soils in Lombok Island, it necessaries to define mineralogy composition through X-ray diffraction analysis (XRD) and thermogravimetry analysis (TGA) of the clay fractions of the soil

Get PDFThis study aimed to determine the effect of the concentration and frequency of Bio-EXTRIM biofertilizer applications and their interactions on the growth and yield of carrot (Daucus carota L.) plants cultivated using pots in the lowland. This research was conducted in the rice fields of Siren Hamlet, East Rumbuk Village, East Lombok sub-district, from March toJune 2019, and arranged according to the Randomized Block Design (RBD) factorial with two factors. The first factor was the concentration of  Bio-EXTRIM and the second factor was the frequency of Bio-EXTRIM applications; each consisted of 3 levels and thus resulted in 9 interractio. The interraction were: concentration of 0.25% with 4 times application, concentration of 0.25% with 5 times application, concentration of 0.25% with 6 times application, concentration of 0.5% with 4 times application, concentration of 0.5% with 5 times application, concentration of 0.5% with 6 times application, concentration of 1% with 4 times application, concentration of 1% with 5 times application, and concentration of 1% with 6 times application. The results showes that the concentration of Bio-EXTRIM biofertilizer had significant effect on the rate of carrot leaf stalks growth, with concentration of 0.25% had the highest leaf stalk growth rate. The frequency of Bio-EXTRIM biofertilizer applications influenced the dry weight of leaf biomass, the middle diameter of the carrot root and the sugar content of the carrot root. The highest dry weight of leaf biomass and diameter of the tuber were obtained in carrot plants treated with Bio-EXTRIM biofertilizer for 4 times, while the sweetest tubers were obtained in carrot plants treated with Bio-EXTRIM biofertilizer for 6 times. However, there was no interaction between the concentration and frequency of Bio-EXTRIM biofertilizers in influencing the growth and yield of carrots grown in the pots in the lowland
Distribusi dan Pola Segregasi Karakter Kuantitatif F2 Persilangan Padi Situ Patenggang dengan IPB 3S
Get PDFThis study aims to determine the distribution and patterns of gene segregation that play a role in the inheritance of quantitative F2 traits resulting from the Situ Patenggang rice crossing with IPB 3S. The method used in this study is an experimental method carried out in July to December 2018 with a single plant cropping pattern. Data distribution was tested by Kolmogorov Smirnov test using SPSS 17.0 software and the suitability of segregation ratio using Chi-Square method with a real level of 5%. The results showed the nature of the number of productive puppies in normal distribution which means the character is controlled by many genes (polygenic). Plant height, number of empty grains and number of filled grains follow Mendel's segregation pattern with a ratio of 15: 1 (double dominant epistasis; controlled by two dominant genes that are both epistasis and regulate the same traits and can replace one another). the nature of the number of non-productive tillers, panicle length, and weight of 1000 grains does not follow the Mendel segregation ratio pattern or its modification for one trait and two traits is assumed because it is controlled by more than two genes (minor genes) so that their individual effects are difficult to distinguish
