Abstract

Penelitian bertujuan mempelajari interaksi sinergis tanaman tomat dan cabai dalam sistem pertanaman tumpangsari di dataran tinggi. Kegiatan penelitian dilaksanakan di rumah kaca dan lapangan, di Kebun Percobaan Balai Penelitian Tanaman Sayuran, mulai bulai Mei sampai dengan Desember 2000. Perlakuan percobaan terdiri atas delapan macam perlakuan tanam tumpangsari, termasuk pertanaman monokrop sebagai pembandingnya. Percobaan rumah kaca menggunakan rancangan acak lengkap dengan dua ulangan, sedangkan di lapangan menggunakan Rancangan Acak Kelompok dengan tiga ulangan. Hasil penelitian menunjukkan bahwa (a) interaksi sinergis tanaman terjadi pada tumpangsari tanaman tomat dan cabai terhadap komponen pertumbuhan tinggi (7 minggu), perkembangan luas daun, bobot kering tanaman pada fase pertumbuhan maksimum, serapan total NPK, dan komponen hasil buah tomat dan cabai (buah sehat dan rusak), (b) efek sinergis tanaman nyata terjadi searah dari tanaman cabai terhadap setiap parameter tanaman tomat; dan (c) sistem interaksi sinergis tanaman tumpangsari di dataran tinggi dipengaruhi cara pengelolaan tanaman  di lapangan. Selanjutnya pengaruh interaksi dua arah dari tanaman tumpangsari sayuran di dataran tinggi perlu diteliti lebih lanjut. Kata kunci: Lycopersicum esculentum;Capsicum annuum; Tumpangsari; Sinergisme; Interaksi; Tanaman sayuran. ABSTRACT. A series of experiment were conducted at screen house and experi- mental garden of  Research Institute for Vegetable, starting from  May to December 2000. Treatments consisted of eight kinds of intercropping systems including monocrop as its control treatment. A screen house experiment used a randomized complete design with two replications, while the randomized block design with three replications was ap- plied in the field experiment. The results showed that (a) the positive plant interaction occurred on tomato and hot pep- per intercropping as shown at growth component of plant height (7 weeks), leaf area, dry weight of crop at maximum growth stage, total uptake of NPK, and the yield components of tomato and hot pepper fruits (healthy fruit and damage fruit), (b) synergism affect of plants significantly occurred directly from hot pepper plant on tomato crop, and (c) the plant interaction system of tomato and hot pepper intercropping in the highland were closely related to cropping man- agement in field. Further study are needed to explore more information deeply in two ways interaction affects of crop- ping sytem on vegetables farming in the highland.

Abstract

This research is to analyze the influence of self-efficacy, emotional quotient, obedience pressure and task complexity to auditor’s audit judgment. Using self-efficacy and emotional quotient as the internal factors and obedience pressure and task complexity as the external factors. Self-efficacy refers to the belief that a person has the capacity to organize and execute the course of action required to produce the desired outcome. Emotional Quotient refers to the ability to recognize and control own feeling in any confusing situation, while obedience pressure comes from department/company there were audited or high rank officers and from professional standards. Task complexity is defined as the numerous tasks that come continuously and confusing the auditor. This research used samples of auditor who works in public accountant office in Pekanbaru, Padang and Batam. This research used convenience sampling method. Research tool used questionnaire which was distributed to the auditors directly or by mail as much 80 and only 35 replayed. The analyzed method used in this research is multiple regression analysis by using SPSS (Statistical Product and Service Solution) 17. The result of this research showed that self-efficacy, emotional quotient, obedience pressure and task complexity affect the auditor’s audit judgment.Keywords: self-efficacy, emotional quotient, obedience pressure, task complexity, audit judgment.

Abstract

This research aims to determine the effect of metode Snowball Throwing against the results of learning mathematic in students class VIII at State Junior High School Rambah Hilir. Data collection techniques using the post test. The writer used test “t” in analyzing the data. Based on data analysis the writer thitung = 2,915 and ttabel = 2,00 at taraf 5%. It show that thitung > ttabel. Therefore the metode Snowball Throwing influence to the result of learning mathematic in students class VIII at State Junior High School Rambah Hilir

Abstract

Good Learning and Quality is the learning that uses right methods and able to interact while Teaching andLearning process. One of the intended learning is using inquiry method. From the result of analysis data it canbe concluded that the application of inquiry method in learning subject of Bangun Datar to improve studentsoutcome in mathematics learning at class VII Semester 1 SMP 11 Rambah Hilir on Academic Year 2014/2015.This is seen from the results of the students evaluation from 24 students, who score ≥ 60 are 19 students

Abstract

Measles is a infectious disease caused by a virus that could be solved one of them with the process of vaccination. This model is based on Xianning Liu 2007), Marentek (2011) and a adding again the assumption that vaccinated individuals have the possibility to stay h healthy but vulnerable to disease, because immunity is only obtained during the process of vaccination alone. SVIR epidemic models, there are two fixed points are points remain free of disease and endemic fixed. If the basic reproduction number is equal to one will obtain a minimum level of vaccination. To make it easier to observe the dynamics of the system as well as the influence of continuous vaccination, then used computer simulations using the software Mathematica 7.0 to give explicit parameters and in accordance with the measles

Abstract

The definition of function f is a role that relates between x of one items and single value f(x) of others items. It can be a real scalar and vector. Scalar function is coming from real counts items and a couple items or a result of a real count items.However, vector is coming from a real count items and the result vector items. They are not so different; vector has direction and value while the real counts only have value. Vector will be analyzed is to prove vector and differential theorem function used to vector in R2.
