Abstract

Research isolation and identification of arbuscular mycorrhiza fungi was conducted in March 2009. The purpose of this study was to determine the genus of the arbuscular mycorrhizal roots tebu.Sampling contained in an area measuring 20m x 20m with a 5 point sampel.Teknik taking isolate spores used in arbuscular mycorrhiza is a technique castings strain and followed by centrifugation techniques . The observations obtained 8 types of arbuscular mycorrhiza spores comprising 7 species of the genus Glomus and one type of the genus Acaulospora .

Abstract

The objective of this observation is to understand the trendof  oil palm fresh fruit bunches  (FFB)within one year and to observe the oil palm yield potential of  small holder. The observation was held in one of small holder plantation located in Desa Sonomartani, Kecamatan Sukarame, Kabupaten Labuhan Batu Utara (north Sumatra). The palms were planted in shallow peat. The seedlings were assuming coming from illegitimate seeds. In general, like any other small holder palms, the farm was not well managed such as manuring was only applied ones per year with dosage 0.5 kg Urea.  Weeding in palm circle and inter row is not totally cleaned.  The observation was done during January to December 2013. The number of palms sampled is 238 palms or more or less one hectare.  The stand trees in the area is 140 palms/ha. Average bunch weight during observation is average on 13 kg. Based on the observation, the trend of one year production was tent to distribute nearly in normal distribution.The yield potential is 21.8 ton FFB /ha/year. However, the actual yield was only around 9.9 ton FFB/ ha/ year. This actual production is still far lower from their potency.  In order the yield achieve their potential, herewith some recommendation (i) The seeds planted much be certified seeds bought  from legal seed producer, (ii), weeding must be done properly in which palm circle, harvesting path and inter-row must be free from any weed, (iii) manuring program must be correct dose, type, time and application.  Drainage must be maintained to avoid water lagging. The palms are also must be kept from any pest & Disease attack and thief.

Abstract

Research on mangrove species diversity in the village of Tanjung Rejo Percut Sei Tuan district in North Sumatra was held in June-September 2012 which aims to determine mangrove vegetation species diversity, species density, frequency and dominance of mangrove species. Primary data obtain by sampling and direct observation by making the observation plots at the study site. Observations indicate that 14 mangrove species classified into eight families. Values of density, frequency and dominance for the highest level of the tree, and the seedling pacang contained on Avicenniaceae. Mangrove species diversity to the next level of the tree is 0.80 and the 1.38 level pacang 1.88 seedlings. The range indicates the diversity of mangrove species is low.

Abstract

ABSTRACTThe study was conducted to observe the haemoglobin level in pulmonary tuberculosis (TB) patient in therapeutic period who received anti tuberculose drugs. Hemoglobin level of Thirty Pulmonary TB patients was examined each month, before receiving any therapy and after the medications was given. Hemoglobin level measurement was continued until the third month of therapy. The observation held at Haji Abdul Halim Hasan Public Health Center in Binjai showed that the hemoglobin level was significantly decrease with the time in pulmonary TB patient especially at the third month of therapy both in male and female patients.

Abstract

Antimicrobial test was conducted on plant root extract som jawa (Talinum paniculatum, jacq. (Gaertn)). Five hundred gram simplicia of som jawa root was macerated using methanol and n-heksana, and coagulated. The screening of extract methanol and n-heksana was done to get metabolic secunder; flavonoid, alkaloid, terpenoid, and saponin. The result of phytochemistry secreening test to extract methanol to metabolic secunder was negative. Antimicrobial test result showed that the extract of som jawa root  is active againts microbes E.coli. Measurement is based on the test zone diameter of the clear zone generated, where . coli has the highest diameter of the clear zone compared with the others microbes such as Staphylococus aureus, Bacillus sp, Serratia sp, and Candida albicans. The values of the clear zone of each microbe  in order are 1,1 cm, 1 cm, 0,95cm, and 0,9 cm. These value were obtain at a concentration of 10%.

Abstract

The title of  this study is the utilization of chitosan from shellfish waste as water purifier. The purpose of the study is to utilize coagulant of shellfish waste in water treatment proes into clear water. The research variabel are the concentration of chitosan 1,3,5,7, and 9 g/l. The particle size of chitosan used in this research is 150 mesh. The time consume  8 hours for purification process. The result showed that 9 g/l chitosan shell waste is effective to water purification process. At a concentration of 9 g/l. Chitosan shellfish waste can produce clean water in complianee with health minister No. 416/MENKES/PER/IX/1990 about  water quality treatment.
