Abstract

Analisis butirsoalpenting untukmengetahui mutu.Soalyang bermutu adalahsoalyangdapat memberikan informasi yangsesuaidengan tujuannya. Tujuan dari penelitian ini untuk mengetahui kualitas soal ulangan harian secara kuantitatif pada materi Struktur dan Jaringan Tumbuhan di kelas VIII SMP Negeri 24 Padang. Penelitian ini merupakan penelitian deskriptif. Analisis soal dilakukan secara kuantitatif meliputi validitas, reliabilitas, daya pembeda dan tingkat kesukaran soal. Hasil analisis nilai menunjukkan validitas termasuk kategori cukup, reliabilitas termasuk kategori sangat tinggi. Indeks kesukaran termasuk kriteria cukup (57,14%), Terlalu sukar (10,20 %), terlalu mudah (32,65%).  Analisis daya pembeda soal diperoleh hasil 8 buah soal dengan kriteria jelek sekali (16,32%), 23 buah soal (46,93%) kriteria jelek, 12 buah soal (24,48%) kriteria sedang dan 12,22 % yaitu sebanyak 8 soal kriteria baik. Dapat disimpulkan dari hasil analisis kuantitatif meliputi validitas, reliabilitas dan indeks kesukaran telah memenuhi kriteria soal yang baik, tetapi daya pembeda soal belum memenuhi kriteria soal yang baik.Kata kunci: Analisis kuantitatif, Struktur dan Fungsi Jaringan TumbuhanQuantitative Analysis of Daily Test Questions on Material of  Structure and Function of  Plant Tissue in Class VIII of Junior High School 24 Padang Analysis of items is important to know quality. Quality questions are questions that can provide information that is suitable for its purpose. The purpose of this study was to determine the quality of the daily test questions quantitatively in the Structure and Plant Tissue material in class VIII SMP N 24 Padang. This research is a descriptive research. Question analysis is carried out quantitatively including validity, reliability, indexofdifficulties, and differentiationof  the  matter  of  test. The results of the value analysis show that the validity includes sufficient categories, the reliability includes a very high category. Difficulty’s indexes include sufficient criteria (57.14%), too difficult (10.20%), too easy (32.65%). The differentiationof  the  matter  of  test was obtained by the results of 8 questions with very bad criteria (16.32%), 23 questions (46.93%) bad criteria, 12 questions (24.48%) medium criteria and 12.22% ie as many as 8 questions about good criteria. It can be concluded that the results of quantitative analysis include validity, reliability and difficulty index have met the criteria of a good question, but the differentiating problem has not met the criteria of good questions.Keyword: Question analysis, Quantitatively, Structure and Plant TissueAnalisis butirsoalpenting untukmengetahui mutu.Soalyang bermutu adalahsoalyangdapat memberikan informasi yangsesuaidengan tujuannya.

Abstract

This research started from the problem of low student results on the material of the virus. It is evident in the quiz grades of students who are under the minimum competence criteria (KKM) so that the value of courses on microbiology and parasitology virus material is not appropriate  as expected. This research purpose to know the implementation learning of microbiology and parasitology at the material Virus in the Apikes Iris Padang which includes the design, implementation and assessment of learning. Informants research is lecture of Microbiology and Parasitology and Students Apikes Iris Padang. This type of research is descriptive research with a qualitative approach. Based on the findings, we can conclude that (1) Lecturers are not planning independently contextual learning context-sensitive places or classrooms where learning implementation. (2) Lecturer implementing the learning has not been effective and efficient due to: (a) lecturers have not been able to utilize time effectively, (b) lecturers have not been able to establish and selecting instructional media appropriate in accordance with the criteria of the study material (c) the learning has not been effective due to the limited number and quality of laboratory equipment. (3) Lecturer already conducted an assessment of student learning outcomes for the quiz with the mechanisms and procedures that have not been right.This research started from the problem of low student results on the material of the virus.

Abstract

The objective of this research is to know the application of guided inquiry learning model to the biology learning result of the students of second years of yunior high school in the affective domain. The study was conducted in the odd semester of the academic year 2017/2018. The research is an experimental research using randomized control group postest only design research design. The study used two sample classes: the experimental class with given the application of Inquiry guided learning model and the control class using conventional learning method. The research instrument used is observation sheet of attitude evaluation. Indicators assessed are responsibility and confidence. The result showed that the average affective value of the experimental class is 82,50 (Good predicate) and the control class average is 73,85 (Good predicate). Working hypothesis accepted because tcount = 3.26> ttable = 1.672, and there are differences in student learning outcomes in both classes of samples significantly. That is means the implementation of Inquiry Learning model can improve the learning outcomes of biology of grade VIII SMP students affective

Abstract

This study aims to determine the growth of mangrove seedlings grown on soil top soil media. Mangrove seeds obtained from the community around the mangrove forest in Taluak Buo Bungus, Padang. This study used experimental method using Completely Randomized Design (RAL) consisting of 4 treatments and 6 replications. Treatment A as a control using land taken from the mangrove forest area of Taluak Buo Bungus, Padang. Treatment B using 100% topsoil soil, Soil top soil treatment (70%) plus cow manure. Treatment of soil top soil (70%) with the addition of chicken manure. Growth factor to be observed in this research is the growth of stem and number of leaves, then also calculated stem diameter ratio at all treatment. The results showed that the treatment on seed height and number of leaves was significantly different with the control, while for the number of different leaves were not real.
