ANALISIS PERILAKU PEMILIH PADA SURVEY PRA PEMILU 2009 MENGGUNAKAN METODE CHAID KURNIA, LELY
Sainstek : Jurnal Sains dan Teknologi Vol 2, No 2 (2010)
Publisher : IAIN Batusangkar

This research studied about the the respondents characteristic at the legislative general pre-election in 2009. The researcher used statistic analysis to see the association and structural connection between variables as the characteristic of voters? behavior. The data used in this study is gotten from the result of a survey on voters? behavior in the form of counting and category data, that?s why the statistic methods used was CHAID. Analysis of CHAID showed that the variables having the strongest association with the party choice is age. CHAID method at the analysis of respondent characteristics of voters in the election resulted in five segments of the party choice of respondents. In each segment, the old party is still the party that is trusted by respondents to represent their voice in parliament.Key words: voting behavior, interaction, chi-square, CHAID method

In the coastal area of west Sumatra, specially west Sumatra represent area which is gristle will of the earthquake, since in the coastal area of west Sumatra can be found plate subduction area active that is Indo-Australia plate to Eurasia plate with necromancy average angle is 31,330 and average speed 6-7 cm/year, and sesar area that spread in the as far as Sumatra Island that caused by necromancy sideway Indo-Australia plate to Eurasia. Aims of this research is creating visualization imaging subduction of Indo-Australia plate toEurasia and change of surface morphology. Method of this research is Development research method or R&D, Data of this research based on old research (Akmam, 2006) and visual imaging from Natawijaya (2005). This simulatin maked using 3D max software, google earth, photoshop, and other software, that result it packet in DVD form. Keywords: simulation, subduction, subduction coastal west sumatera

The gasoline purity test has been carried out in several retailers inPadangcity using Mercury atomic absorption spectroscopy method. As an object of study was taken 10 samples of gasoline were sold in stalls scattered retailers in the city ofPadang, for subsequent comparison with standard samples that taken from Pertamina Teluk Kabung Padang. Spectrum produced by each sample was analyzed based percentage difference between the spectrum peak, the angle position and the sample wavelength. To determine the level of gas purity, the mixing gasoline with kerosene have been done with the percentage ratio of 5% to 25%. From this research, it appears that gasoline retailers in the region of Batas Kota, Air Pacah and Pasar Baru indicating that the mixing of gasoline and kerosene to achieve the highest percentage, namely 25.3%, 23.2% and 17.2%. Meanwhile, the regions with the lowest percentage of blending gasoline and kerosene are in the area of Tunggul Hitam, Kuranji and Bungus, namely 3.7%, 5.0% and 4.9%.Key words: purity, gasoline, several retailers, atomic spectrum

PEMAKAIAN PREBIOTIK UBI JALAR KUNING (Ipomoea batatas L) DAN PROBIOTIK Lactobacillus casei PADA PEMBUATAN SUSU FERMENTASI SINBIOTIK FAJAR, NAJMIATUL; Indriati, Gustina

Publisher : IAIN Batusangkar

This research study about use of prebiotic Ipomea batatas L. and probiotic Lactobacillus casei at milk fermentation. The usage of simbiotic increase, recentely, especially, for husbandarys products, such as milk fermentation the purpose of this study was to find out the best composition of prebiotic Ipomoea batatas L and probiotic Lactobacillus casei given in the process of simbiotic milk fermentation. The method used for this experiment was random cluster, factorial 4 x 3 with 3 times of re-treatment, and was analyzed with BNT and BNJ testing. ?A? factor was the use of prebiotic Ipomoea batatas L. (0%, 7,5 %, 15 %, 22,5 %), and ?B? factor was the use of probiotic Lactobacillus casei (2%, 3%, 4 %) the component measure were BAL , water and TTA the result of this study was shown that the best use of prebiotic Ipomoea batatas L and probiotic Lactobacillus casei in the process of symbiotic milk fermentation were in the composition of highest BAL : 21,40 x 108 cfu/ml. the highest TTA and water were 0,21 % and 71,98 22,5 % of prebiotic Ipomoea batatas L. and 4% probiotic Lactobacillus casei consentrate. Key words: prebiotic, Ipomea batatas L., probiotic, Lactobacillus casei, milk fermentatio

UJI DAYA HAMBAT VIRGIN COCONUT OIL (VCO) TERHADAP PERTUMBUHAN Candida albicans SECARA IN VITRO Yunarti, Elsa
Sainstek : Jurnal Sains dan Teknologi Vol 2, No 2 (2010)
Publisher : IAIN Batusangkar

This research was found effectivity and correlation Virgin Coconut Oil (VCO) on number of growth Candida albicans in vitro incubation. Dilution method was use to dilute suspension of C. albicans on Sabouraud's medium. Then, C. albicans was account at 37°C in 24-48 hours incubation. Bioactivity test were replicated three times. Data analysis used SPSS for window 12. One-Way Anova and correlation test use to differ treatment. The research was found number of C. albicans was lower with add of VCO. This result was different at (p<0,05). Correlation test was conducted number of VCO with C. albicans. Then, VCO was effective to defect of growth C. albicans in vitro incubation and there were correlation number of VCO with C. albicans on Sabouraud's medium.Key word: virgin coconut iil, Candida albicans, effectifity, incubation in vitro

Publisher : IAIN Batusangkar

This paper introduces Auslander-Reiten Sequences in mod A, where A is a finite dimensional -algebra. We will also introduces almost split morphism, as a special form of morphisms, which will provide a natural way to present the form of Auslander-Reiten sequences. These sequences are particulary useful in representation theory of algebras.Key words: almost split morphisms, , irreducible morphisms, almost split sequences

A important component of teaching learning process is teaching material. A good teaching material will produce optimal and new (recent) teaching learning process. Internet is a source where we can find and get the new teaching recently. To find the teaching material, we have to know the computer identity where the teaching material is located. The Internet can be categories into 2 categories namely edu (education) for computer which located in United State and ac (academic) which is followed by country code for computer which located in the outside of United State. Filtering information with Search Engine include Power Searching Conceptual with application need technique for get information is expected. Key words: filter, information, website, teaching material, find and get

MENANGKAL RADIKAL BEBAS DENGAN ANTI-OKSIDAN KHAIRA, KUNTUM
Sainstek : Jurnal Sains dan Teknologi Vol 2, No 2 (2010)
Publisher : IAIN Batusangkar

This article aims at understanding free radical and how antioxidant can neutralize it. This reactive and unstable chemistry molecules could destruct cell. Free radical coul be formed automatically by respiration result or generate from external factor like air pollution, cigarette smoke, emition of vehicle or access of UV light. To stop free radical, it must be concerned seriously that the supply of antioxidant in our body is sufficient. Endogenus antioxidant must be added by exogenus antioxidant to make it react with free radical to produce stable molecules.Key words: free radical, antioxidant
