Abstract

The  research was  conducted to  test  the  potency  of  several local  maize genotypes (landraces) of Southeast Sulawesi and to find the genotypes that were tolerant to less water conditions. The research was performed in  a  plastic house at  the  experimental farm of Agriculture Faculty, University of Halu Oleo.  The research was arranged in a Randomized Complete Design (RCD) with 2 treatment factors. The first factor was water availability level (A), consisted of 3 (three) levels (A0, A1 dan A2), and the second factor was maize genotype, consisted of 9 local maize and 1 national variety (Arjuna).  Research results showed that the less water conditions (A1 and A2) had negative effects on maize vegetative variables (plant height, plant diameter, leaf number and length of leaf tip).  On the other hand, the genotype treatment had significant effect on plant height, plant diameter, and length of leaf tip. Genotipe G7 dan G6 had the highest plant height, while G1 had the biggest plant diameter. Keywords: less water condition, local maize genotype, vegetative stage

Abstract

Pesticide is one of dangerous chemical compounds in environment. Its existence has spread so it can cause negative effect for human. Pesticide compound is toxic in for nervous system so that a quick detection system is needed to protect human’s health and as a control for agricultural product. Therefore, we conducted a research of electrochemical biosensors development  based  on  enzyme  acetylcholinesterase  in  electrode  to  analyze  pesticide residue  so  that  a  more  superior  and  reliable  biosensors  can  be  obtained  for  pesticide residue analysis in foodstuff samples, especially for agricultural product. Residue analysis of carbamate and organophosphate in foodstuff sample requires a sensitive, selective, cheap- and-easy-operated, and quick-analyzed tools. A new research has been designed in making of  biosensors electrode by  using immobilization method of  enzyme  acetylcholinesterase (AChE) with the supporting materials of Acetate Selulose (AS) and Glutaraldehid (GA) in biosensor electrode connected with electrochemical transducer. Designed biosensors were characterized, including Nernst factor, the detection limit, response time, and period of use. Next,  biosensors  were  tested  in  sample  of  vegetables and  fruits.  Expected  result  was  a biosensor prototype with better work than pesticide determination with instrument of Gas Chromatography (GC) and High Pressure Liquid Chromatography (HPLC). Biosensor development offers low cost, accurate, quick analysis time, and sensitive to detect pesticide residue. Keywords: : Pesticide, Biosensor, Electrochemical, Enzim, Sensitive

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,
