Abstract

Flavonoids are phenolic compounds found in many plants and some species canact as antioxidants. Antioxidants are a substance very easily oxidized, so that when thereis an air / oxygen would oxidize antioxidants first before oxidize other substances.Penilitian result of various crops showed varying levels of antioxidants in each plant.This study aims to determine the levels of flavonoids in several medicinal plants arewidely consumed by humans is the parasite tea, red betel leaves, soursop leaves, fruit andleaves of gotu kola gods crown. From the research results for the five materials tested,mistletoe tea has the highest concentration of flavonoids. Research carried out by theextraction time of 120 minutes, the concentration of ethanol 96%, stirrer speed of 300rpm and a temperature of 70 ° C solution obtained parasite tea flavonoid concentrationof 0.575 g / L, the mass transfer coefficient (Kca) is calculated based on the results ofexperiments for the extraction of tea flavonoids parasite 0.00863382 min-1.Keywords: flavonoids, extraction, plant

Abstract

Development of chrysanthemum plants in the medium plains is still facing obstacles due tounfavorable climate. Until today, the availability of tolerant chrysanthemum seeds grown in the mediumplains is not maximized so that the necessary effort in order to increase the genetic diversity as thematerial selection to obtain tolerant chrysanthemums grown in medium plain. This research is beingconducted in order to follow up the problems of availability of tolerant chrysanthemums seeds grown inthe medium plains at several stages. Stage one is the induction of callus after gamma ray irradiation invitro. This research has been conducted in tissue culture laboratory of the Faculty of Agriculture UPN"Veteran" Yogyakarta from February to June 2015. Tested regeneration media is ½ MS with the additionof IAA 0.1 mg/l; 0.2 mg/l; 0.3 mg/l; 0.4 mg/l and 0.5 mg/l. The results showed that ½MS regenerationmedia with the addition of IAA 0.3 mg/l spur sprouts emerge percentage (100%); while growing sprouts(8.67 days), height are about sprouts (3:10 cm) and number of sprout (7:00). Regeneration mediumTreatment with kinetin 2 mg/l + IAA 0.5 mg/l gives the number of root growth (13) and root length (4:07cm)Keywords: Chrysanthemum, tolerant medium plains, in vitro selection, gamma ray irradiation,

Abstract

The research location is located in Paningkaban area and its surrounding areas that included in the areaof Gumelar Subdistrict, Banyumas Regency, and Central Java Province. The objective of the researchwas to show the presence of any structural geology control on research area that affect the distributionpatterns of quartz vein and gold/ore mineralization.The methodology in this research begins with data collecting process, which this preliminary data is thenbeing compiled to determine the next phase of the study. This study covers the geomorphology,stratigraphy, any structural and alteration mineralization observation. The geomorphology of the studyarea composed of the four original forms: volcanic, structural, karsts and fluvial form. The stratigraphycomposed of seven unclassified litho units and two litodem, namely (from old - young): Halang volcanicbreccias unit, Halang sandstone unit, Kumbang andesite lava unit, Tapak volcanic breccias unit, Tapaksandstones, unit Tapak limestone unit, alluvial deposits, and andesite intrusion.Hydrothermal alterations formed in the research area are carefully grouped into three types of alterationzoning and they are argillic alteration, propylitic alteration, and sub-propylitic alteration. Themineralization then is carefully classified as pyrite (FeS2), chalcopyrite (CuFeS2), galena (Pbs), bornite(Cu5FeS4). The macroscopic analysis of the structure in the study area based on the alignment of allegedtraces of the geological structure in the form of fault, or directions of the fold axis alignment, obtainedthe general alignment directions trending N 305° E (NW - SE), and N 055° E (NE - SW).In the research area, the mineralization process is controlled by geological structure such as fault andjoint. The appearance of the mineralization is abundant and can be found many fulfilling the joint zonemainly shear joint trending Northeast - Southwest and Northwest - Southeast, the direction of jointsharpness measured in the field relatively trending North - South. This study will emphasize on themeasurement and detailed analysis to know more about the gold mineralization process and otherminerals controlled by structures patterns. The structural control analysis can really be a good helpinghand in locating the mineralized areas because basically the activity and geological structure controlprocess are corridor for magma and the its rest compound that brings minerals, so the methods ofmineral ores exploration by structure control can be used in determining ore gold mineralized depositsprecipitate on gold deposits system and other minerals on a different area.Keywords: lithostratigraphy, structure, zone of opening, zone of alteration, mineralization, metalminerals

Abstract

Underground water is a component in the hydrological cycle which takes place in nature,formed by rainwater that seeped into the soil in the recharge area and flew through the media layer ofrock acting as a carrier layer of water (aquifer) in ground water basin, where is under the groundleading to discharge area. Wates basin’s groundwater includes the Wates, Temon, Panjatan, Lendah,Brosot, a little part of the Sentolo and Pengasih District located in Unit Plateau of volcanics fluvio,beach units and sand dunes with the alluvial material consisting of sand, gravel, silt, and clay, flatmorphology, relative lithology and groundwater characteristics. This lithology is potential with theoccurrence of groundwater conservation system changes if there is an excessive ground waterextraction in the region which can be characterized by the increase in salinity in ground water.The main objective of this study is to fully assess the qualitative and quantitative groundwaterin the Wates Groundwater BasinBasin due to Temon International Airport construction in its relationto maintain the sustainability of groundwater systems.The methods in this study consists of several steps, starting from observation and rock’s / soildescription include: measurement of rock bedding, measurement of structural geology elements,observation of morphological conditions, and sampling soil / rock to be tested in laboratoryconcerning about the content of its mineralogy, texture and structure. The cross-section will showtheinformation of quantity / amount of groundwater that exist in the research area and the coastidentification towards the potential intrusion of sea water. The results of mineralogical analysis ofrocks and hydrochemical groundwater will provide information on the distribution of groundwaterquality. This conditions will certainly change the start of construction and post construction of theairport. Information about the mineralogical content of rocks, hydrochemical content of water andaquifer configuration will be able to contribute as an efforts in the groundwater area of InternationalAirport Temon, DIY.Keywords : groundwater, aquifer, electrolite conductivity,seawater intrusion

Abstract

Pathuk Hill is located abouth 15km eastern from Yogyakarta City. Pathuk Hill is elongatedhill (escarpment) trending NE-SW stricking and formed the steep slopes to the north-west.An average height of a Pathuk Hill between 200m-250m above sea level. This hill arecomposed by interbadded tufaceous sandstone and tuff of Semilir Formation in the lowerpart. Conformity above of Semilir Formation is volcanic breccia of a solid NglanggranFormation. In the top of the Pathuk Hill we can see the exotic view of Yogyakarta City in thewestern, Merapi Vocano in the north-western and sunset in the western in the afternoon. Inthe Pathuk Hill resort will be development of the big resort as the gateway to the WonosariCity. This area would be developed as a torism object between Yogyakarta City andWonosari City.Keywards : Pathuk Hill, slope tability, resort, view, torism object.
