Abstract

Spatial analysis on erosion potential is required to create an integrated management of  watersheds, thoroughly and,  environmentally sustainable, where  the  watershed  as  a management unit. The research was conducted in the watershed area Moramo South Konawe. This research was conducted through an overlay approach using geographic information system (GIS) map of Thiessen polygons, slope maps, soil maps and land use maps. The study obtained five classes of erosion potential, namely very light (2685.60 ha or 21.27 %); light (2359.08 ha or 18.68 %); medium (903.70 ha or 7.16%); heavy ( 381.63 hectares or 3.02% )  ;  and very heavy 6297.94 hectares or 49.87 %). Dominant erosion hazard  level  in  the  basin  Moramo  was  in  the  District  Moramo,  approximately 3496.75 hectares or 27.69 % of the total area of  the watershed Moramo and had been used for agricultural land for approximately 3992.48 hectares or 31.62 %. Keywords : Erosion, GIS, Moramo, Watershead Management,

Abstract

The Study on Contribution of Temperature and Solar Radiation Intensity to Frogeye Disease Development on Tobacco. Tobacco is an important plant in Indonesia, due to its contribution to Indonesian economic and employment opportunity. One of the limiting factors in tobacco production is frogeye leaf spot, a fungal disease caused by  Cercospora nicotianae Ell. et Ev. Epidemic of this disease was supposed to have a close relationship with weather aspects, such as wind velocity, temperature, solar radiation intensity and relative humidity.. The experiment carried out at Mycology Laboratory, Study Program of Plant Pest and Disease, Faculty of Agriculture, UGM and two tobacco plantations in Jember a nd Klaten to study contribution of temperature and solar radiation intensity to frogeye disease development on tobacco. The results showed that frogeye disease development was support by weather elements. i.e. temperature, but solar radiation intensity is not important factor to disease development. Key words: tobacco, temperature, solar radiation intensity, frogeye disease development

Abstract

Rice is an important food crop in the world, exceeding potatoes, corn, wheat and other cereals. The experiment was conducted to study differences in the  growth characters of some progenies from the crosses of upland rice and to know the cross combinations which produced the best growth characters. The research treatment was seven progenies from crosses of upland rice.   Seven progenies of the rice grown in the field experiment were evaluated based on morphological characters, especially rice stems and leaves. Based on the stem color and the color of the sheath, there were two groups consisted of F2 plants population of progeny A (33/Wagamba (1)), E (Wagamba/33), and F (33/Wagamba (3)) with the color purple midrib purple stem and base. In the second group contained of the F2 plant population of progeny B ( 33/Wagamba (2)), C (Cegelius/Wangkoito (1)), D (Cegelius/Wangkoito (2)), and G (33/Wagamba (4)) with the base of the stem and sheath color were green. The progeny A (33/Wagamba (1)) and progeny E (Wagamba/33) were the best progeny because it had several advantages such as growth form upright, erect leafs, plant height, number of tillers, and dark green leaves. Keywords: growth character, crosses, upland rice, progeny, selection.

Abstract

ABSTRACT A variety of methods are available for analysing repeated measurements data where the outcome is continuous. However, there is little information on how established methods is compared in practice with methods that have become available to applied statisticians more recently, and multilevel models. The aim of this paper was to exemplify the use of this method, and directly compare the results by the application of a hypothetical data set. The focus was on practical aspects rather than technical issues. The data considered were taken from a livestock trial of treatments for pasture in 20 chows, in which a baseline and four post-randomization measurements of outcomes were taken. The simplicity of the method of summary statistics using the post-randomization mean of observations provided a useful initial analysis.Key words: Analysis of variance, repeated measures, applying in broad aspects

Abstract

Kurang  responsifnya eksplan  terhadap  medium  invitro  dan  efisiensi  transformasi yang relatif rendah merupakan kendala umum yang dihadapi pada transformasi genetik tanaman legum.   Pada tanaman lupin, satu spesies legum, sebagian besar klon yang diperbanyak dari satu tunas transgenik (single transformation event) sering tidak mengandung gen yang ditransfer (transgene), dan menghasilkan keturunan yang tidak transgenik, walaupun awalnya plantlet tersebut terbukti transgenik. Kimera (chimerism) diduga sebagai penyebab dari penyimpangan segregasi gen (reduced transgene segregation) ini.  Penelitian ini mencoba untuk membuktikan isu kimera tersebut. Uji in-situ PCR dan uji histokemikal GUS & lokalisasi selular dari transgen (dalam hal ini gen gus) dilakukan untuk mengetahui apakah dan dimana transgen tersebut terekspresi pada tunas lupin trasngenik generasi T0  tersebut.   Uji in-situ PCR dan histokemikal GUS menunjukkan bahwa GUS umumnya terekspresi pada beberapa bagian dalam batang tunas (plantlet T0) dan tidak tersebar merata. Hasil ini memberikan bukti struktural yang penting bahwa transgen terekspresi  secara  sektorial  pada  tunas  lupin  generasi  T0.    Ini  sekaligus  membuktikan bahwa tunas lupin generasi T0  benar-benar kimera, dan menjadi penyebab penyimpangan segregasi transgen pada generasi T1.   Upaya-upaya perlu dilakukan untuk mengurangi kejadian kimera ini, sekaligus mendapatkan ekspresi gen yang solid pada tunas (plantlet) lupin (solid transformant). Key words:   Chimera, transgene segregation, in-situ PCR, GUS histochemical assay

Abstract

The research aiming to study the characteristics of the soil parent material ultramafic Complex Geologic Formations in the Southeast Sulawesi has been carried out in December 2010 to  June 2011 .  Fieldwork was conducted at  two different locations, namely in  the District Lasusua, North Kolaka and in the District Puriala, Konawe. Laboratory studies were conducted using thin section rock and extraction with concentrated acid extraction using HNO3 + HF to determine the mineral composition and chemical composition of total elemental rock. The research results showed that the type of host rock found commonly included peridotite and serpentinite group which were the main constituents of the rock group  Ultarmafik complex  geological formations. The  dominant  mineral  found  in  rocks peridotite included olivine followed by some minerals such as antigorit accompaniment, enstantit, and hornblende, picotit, plagioclase feldspar and anthophyllit. The dominant mineral types found in serpentinite rocks included olivine and antigorit accompaniment followed by  minerals such as  enstantit, plagioclase feldspar and  anthophyllit. Elemental composition of the rock group ultramafic complex geological formations were characterized by low contents of SiO2  and Al2O3  compared to other rocks, as well as contained relatively high MgO, CaO and Na2O. Kata Kunci : soil parent material, geologic formations, mineral composition, ultramafic,
