The existence of earthworms in agricultural land can increase soil fertility and also support a sustainable agricultural system. This study aims to determine the abundance and distribution patterns of megadrilli earthworms in the Bengkulu Kabawetan Tea Plantation. Determination of the research location used the stratified sampling method which consisted of altitude strata, namely an altitude of 800, 900, and 1000 meters above sea level. The samples of earthworms were taken using the quadratic method (30 x 30 x 20 cm) and the hand sorting method as many as 15 plots for each location. The data were analyzed for population densities and distribution patterns using the Morisita Index formula. The results showed that only one species of megadrilli earthworm was found Pontoscolex corethrurus in tea plantations. The highest earthworm population density was at a location of 1000 m above sea level (89.66 individuals m), followed by a location of 900 m (70.33 individuals m), and the lowest density was at a location of 800 m (24.44 individuals m). Statistically, it showed that the densities of the earthworm population at an altitude of 1000 m and 900 m were not significantly different, but it was significantly different from an altitude of 800 m. The distribution pattern of megadrilli earthworms based on the Morisita Index value showed that the three locations have a clustered pattern.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72650071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Old gnetum seeds were ground to make powders. The powders were homogenized in ml PBS buffer containing anti-protease PMSF in a cool room. The homogenate was centrifuged in order to separate supernatant from pellet. Solid media were punched with a perforator, so the results were discs of papers, plastics, and nitrocellulose membranes. The solid media perforated discs were then dipped in gnetum total protein supernatants. The dipped discs were air-dried for a while. Human erythrocytes of all ABO groups were washed three times and diluted to suspension of 20% (v/v) in NaCl 0,9% (w/v). A small drop of erythrocyte suspension was put in middle of each solid media disc, and its blood suspension was spread evenly. Next, the disc was observed under an USB digital microscope to see whether there was erythrocyte immobilisation on solid media coated with total proteins of gnetum seeds or not. All the erythrocytes from human ABO groups were bound effectively, from strongest to weakest,to paper filters, nitrocellulose membranes, and plastics. The future use of erythrocyte immobilisation on a variety of solid media coated with of gnetum total protein seed may be useful for diagnosing diseases related patological erythrocytes with a specific marker.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89631022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In connection with this, the determination of the plant growth is necessary in order to obtain information of manglid ability in producing wood. The purpose of this research was to determine the growth variation of the manglid plants that planted at the Candiroto with an altitude between 457-464 meters above sea level, Candiroto District, Temanggung Regency, Central Java at the age of 42 months. The research method used was a Randomized Complete Block Design with the seedlings propagated from 100 parent trees, separated into 10 blocks, each block consisted of 4 tree plots, and the planting distance was 4 m x 3 m. The characteristics of plant measured were the height of the plant, stem diameter, and life percentage of manglid. The measurement results were analyzed for the variation and tested by employing a Duncan Multiple Range Test. The results showed that the height of plants was ranged between 106-1083 cm with an average of 577 cm. The stem diameter was ranged between 1,3-28,7cm with an average of 9,4 cm. The life percentage of plants was ranged between 17,5-80,0% with an average of 51,3%. The analysis results showed that the parent tree has significant effects on the total height and the stem diameter of plants. There were some variations of height characteristic from 100 parent trees, there were 23 groups, while for the stem diameter characteristic, there were 11 groups.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89684622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphorus in the soil in bonds with metals such as Al and Ca, especially in acid soils such as ultisols. This form of phosphate must be mineralized or dissolved using phosphate solubilizing bacteria. The ability to dissolve phosphate also correlates with the production of Indole Acetic Acid (IAA), which can increase plant growth. This study aims to assess the ability of phosphate dissolution and IAA production of three phosphate solubilizing bacteria (EF.NAP 5, EF.NAP 7, and EF.NAP 10) which have been isolated from acid soils, Lampung. The method used was the clear zone test for bacterial isolates, phosphate solubility, and measurement of IAA production during the phosphate solubility process. EF.NAP 7, EF.NAP 5 and EF.NAP 10 isolates had phosphate dissolution indexes of 0.986 (6th day), 0.828 (7th day) and 0.789 (3rd day), respectively.
