Pedigree construction is one of the ways to seek the inheritance pattern of disease. Three generations pedigree has many benefit in genetic counseling session particularly in establishing a specific inheritance pattern such as autosomal recessive or dominant. This research aimed to analyze three generations pedigree in the family of ID and MCA patients in the Special school of Kendal. This is a descriptive observational study using the interview method in 33 student guardians or parents of ID and MCA students. Twenty-five of 33 respondents collects the complete data. This study showed that three generations of pedigree construction of 8 respondents could not conclude the inheritance pattern. The data showed that two pedigree are suspect of chromosomal abnormalities in the presence of family history with similar disorder, family history with ID and MCA, and family history with IUFD or stillbirth. Further investigation using cytogenetics, FISH, and microarray is needed to establish the diagnosis

The low production of soybeans in the West Pasaman district is due to severeal factors, including the lack of community knowledge in soybean farming which results in less productive yields obtained by farmer and the high use of inorganic fertilizers continuously resulting in less productive soil. This study was experimental research using a completely randomized design (CRD). The treatments given were 6 treatments and 5 replications, the treatments used were 15 gram TSP (A treatment) as control treatments, 300 gram bokashi (B treatment), 400 gram bokashi (C treatment), 500 gram bokashi (D treatment), 600 gram bokashi (E treatment), 700 gram bokashi (F treatment). The data obtained were analyzed by analysis of variance and then continued by LSD test at α level of 5%. Observed parameters were the number of planting seeds and weight of 50 seeds per plant. The results of this study indicated that bokashi fertilizer had no significant effect on the number of seeds but it had significant effect on the weight of 50 seeds and the best result was found in B treatment (300 gram bokashi/polybag). This research had environmental conditions with temperatures of 30 – 340 C, environmental humidity of 63 – 80%, wind speeds of 0,2 to 2,8 m/s, and soil pH of 5,4 to 7,0.

This research aims to determine the diversity of habitus and species that dominate in the region of Kinahrejo, Umbulharjo, Cangkringan, Sleman. The method used is square sampling by making a 7x7 meters square plot of 2 plots so that an area of 98 m2 is obtained. Vegetation analysis using the method of observation, and monitoring (field observation) directly with random sampling and using the principle of representative. Analysis the level of habitat diversity using the Shannon-wienner Index and determination of species that dominate using the calculation of the Important Value Index (INP). A total of 34 species consisting of mosses, shrubs, herbs, and stand-structure are occupy the observation area. The results of the research and analysis showed that Tamarindus indica, which included stand-structure habitus had the highest INP of 139.54% and the lowest INP was found in shrubs habitus. The highest Shannon-wienner index in shrubs habitus is 1.220928 and the lowest is in stand-structure habitus. It can be concluded, stand-structure habitus dominates the area while, the highest diversity is found in shurbs habitus. The eruption in 2010 caused damage to ecosystems and invasive plants to become dominant such as Acacia decurrens and shrubs.

This study obejctives to determine the distribution maps and identify the morphological character of local Mangga Podang at five sub-districts in Kediri. This research used purposive sampling method for collecting data. Coordinate of local mango wasanalyzed using QGIS software version 3.6. Morphological characters are examined by observing the morphology. Microclimate factors that were measured are altitude, intensity, temperature and moisture of soil and air, soil pH, and soil nutrient. Morphological characterswere analyzed for homogenity by statistical test. The results showed that Mangga Podang distribution has spread in residential areas and has different altitude factors between 85-459 meters above sea level. The total population(individu/400m2) found in this study were Mojo10(11.2%), Banyakan 17 (19.1%), Grogol8 (9%), Semen 3 (3,4%)and Tarokan51 (57.3%). Mangga Podangof Kediri Regency generally have homogenous morphological characters, but there were the special character which differs each other, they are the number of flowers in 1 panicle, the weight of ripe fruit and exocarp color of ripe fruits. This morphological variation dependent to light intensity, altitudinal, the velocity of wind and soil nutrient factors.
