Symbiotic nitrogen fixationis a key factor in the low-input farming systemto sustain long time soil fertility. Symbiotic nitrogenfixation involving host-specific symbiotic interactionsbetween root nodule bacteria, termed rhizobia,and legumes. One of the major strategies forenhancing symbiotic nitrogen fixation by legumesin crop production systems is through rhizobialinoculation. But inoculation not always successfuland one reason is the population of indigenous rhizobiumcontained in the soil. Indigenous rhizobium cancompete with rhizobium inoculant through populationdensity and effectiveness. The high populationof rhizobium in one place relating to the type oflegume that ever grew / grown. When the numberof indigenous population is low, not effective or notcompatible with legumes planted the rhizobiuminoculation is required. But when the number ofindigenous rhizobium population is high, effectiveand compatible with legumes that will be planted(based on observations of root nodules and existingplants), inoculation is not required.

A sedimentology survey was conducted during “Pelayaran Kebangsaan” research activities with a marine vessel of "Baruna Jaya VIII" in Karimun Java Sea. The objectives of the research were to determine the characteristics of marine water and its sediment, which are important control for coral reef growth in the study area. The survey acquired samples of Total Suspended Sediment (TSS) and gravity coring. Several analyses were then carried out on those samples; TSS analysis to determine the amount of suspended sediments in sea water that reflect the water quality for marine ecology, stratigraphic profile and sediment thickness pattern analyses to determine the sources of sediment, and grain-size analysis based on granulometry to determine deposition energy and grain-size distribution in the area. Those analyses were both conducted on-board Baruna Jaya VIII research vessel and P2O LIPI laboratory in Jakarta. The results showed that in Java Sea nearby Karimun Java Islands, the sediment supply came from the surrounding islands. Two sedimentary units were found in this area. The first units has thickness of tens centimeter from sea bed surface. It is characterized by grayish green color, grain size variation from clay to coarse sand, soft or low density and abundance with shells. The second unit is located beneath the first one, indicated by sharp contact. It is characterized by brownish color, higher density resembling the density of rock, less compacted and can be broken easily by hand, with occasionally thin carbon lenses or remnant of decomposed vegetation, and less shell or fossil At sea surface, TSS distribution shows value between 0.018 and 0.034 gr/l, with average of 0.025 gr/l, whereas at near bottom sea, it ranges between 0.024 and 0.030 gr/l, with average value of 0.027 gr/l. The granulometry shows that more than 50% of sediment is characterized by the abundance of grain size greater than 3 phi. It suggest that sea water around Karimun Java Islands was clear and the current was relatively calm. These conditions were relatively stable for a long time span. Those sea characteristics were important for successful growth of coral reefs and its complementary marine biotas. However, further studies and researches based on chemical and physical characteristics of sea water, and plankton and microbiology variation and abundances are necessary to confirm those presuppositions.Keywords: total suspended solid, gravity coring, stratigraphic profile, granulometry, Karimun Java Sea

The research is aimed to: 1) describe the process of managerial supervision using group technique to improve the principals’ supervisory competence; and 2) imrove the principals’ supervisory competence at Gugus II Bima UPTD Dikpora Kecamatan Serengan of Surakarta academic year 2012/2013 through managerial supervision using group technique.The type of the research is an action research. The research was done at Gugus II Bima UPTD Dikpora Kecamatan Serengan of Surakarta. The subjects of the research were 6 principals at Gugus II Bima UPTD Dikpora Kecamatan Serengan of Surakarta. The data collecting techniques were done using observation, interview and document techniques. The data analysis technique was done using Kemmis and Taggart model.The research concludes that: 1) the managerial supervision processes were done in three stages, namely: initial stage, observation stage, and feed-back stage; and 2) the managerial supervision using group technique is effective in improving the principals’ supervisory competence at Gugus II Bima UPTD Dikpora Kecamatan Serengan of Surakarta academic year2012/2013. It is demonstrated by the score improvement in each cycles.

This study aims to determine which cultivars of Brassica oleracea var.Botrytis.L highest potential and determine the optimum dose combinations that produce productivity Brassica oleracea var. Botrytis.L best. The study was conducted at the Green-House Fak.Pertanian UPB from May to October 2014. Using RAL design. With Factorial consist of: Factor I (cultivars) with the code K: K1 = White Shot , K2 = Profta and K3 = Snow White. Factor II combination Cromolaena odorata (O), corn waste compost (J) and NPK fertilizer with C code consists of: C0 = Control; C1 = 100%NPK; C2 = 5%O+5% J+0%NPK; C3 = 5%O+2,5%J+50%NPK; C4 = 2,5%O+5% J+50%NPK; C5 = 5% O+5%J+50%NPK. Each treatment combination was repeated 3 times with 2 sample so that there are 108 plant experiments. Observation research through parameter; plant height (cm), number of leaves (leaf), weight of flower (gr), and dry weight (gr). Based on the analysis of waste compost corn and Chromolaena odorata, nutrient content is relatively high compared to NPK-manure. From the analysis of the interaction parameter is generated on a dry-weight that significantly, plant height, leaf number, the weight of flowert significantly affect compost while cultivars real effect on the number of leaves. The highest rates of plant height k1c3 (22.67cm), number of leaves k2c2 (22:00 leaf), dry weight k2c3 (45.75 gr) and weight of flower k3c3 (119.03 gr). Based on the data analysis of the influence of the observer and cultivars with waste compost corn and Cromolaena odorata more responded by vegetatitif growth while the generative growth is not maximized. Allegedly during the implementation of relatively high temperatures (>30oC)

Background: The Endoscopy Unit of Indonesian Air Force Central Hospital Dr. Esnawan Antariksa, Jakarta, Indonesia, has just been established in late 2004 and it is still in developing process. This study was aim to depict the profile of patients who underwent esophagogastroduodenoscopy procedure in the unit. Method: This study was a retrospective study that analyzed data in endoscopic registry of patients who underwent esophagogastroduodenoscopy (EGD) examination from September 2004 to December 2007. Result: Total of 108 patients underwent EGD examination, comprised of 66 (61%) males and 42 (39%) females, with average age of 45.4 years old (range 16-77 years old). The most frequent indication for EGD was dyspepsia 63%, followed by hematemesis-melena 26% and dysphagia 5.5%. Among patients with dyspepsia, EGD revealed organic abnormalities in 71% patients, with descriptions of erosive gastritis 35%, gastritis 18%, bile reflux 7%, esophagitis 5% and gastric ulcer 3%. Among patients with hematemesis-melena, EGD revealed abnormalities, which were described as erosive gastritis 48%, esophageal varices bleeding 22%, gastric ulcer 18%, caustic injury 4%, and esophagitis 4%. Conclusions: EGD is an important procedure to ascertain the occurence of organic abnormalities in patient with gastrointestinal symptoms and signs e.g. dyspepsia and gastrointestinal bleeding. More than half of patients with dyspepsia showed organic abnormalities. Among patients with hematemesis-melena, erosive gastritis is more common than variceal bleeding. Keywords: esophagogastroduodenoscopy, dyspepsia, upper gastrointestinal bleeding, hematemesis melena
