Abstract

ABSTRAK: Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar sikap siswa antara kelompok siswa yang mendapatkan perlakuan model pembelajaran kooperatif NHT dan model pembelajaran kooperatif STAD pada pembelajaran biologi sistem pencernaan. Penelitian ini dilaksanakan di SMA Negeri 2 Gerung pada siswa kelas XI jurusan Ilmu Pengetahuan Alam semester genap tahun pelajaran 2014/2015. Penelitian ini merupakan penelitian kuasi eksperimen dengan menggunakan rancangan Type Between Group Design dengan Posttest Only Design. Populasi penelitian berjumlah 44 siswa terdiri atas dua kelas, dimana keseluruhan populasi dijadikan sebagai sampel penelitian. Melalui teknik simple random sampling ditentukan dua kelas eksperimen. Data yang diperoleh dianalisis dengan menggunakan analisis statistik deskriptif yaitu dengan menghitung rata-rata dari jawaban yang diberikan kemudian dinyatakan dalam bentuk angka persentase dari setiap pernyataan. Angka persentase yang menggambarkan sikap pada indikator: rasa ingintahu, tanggungjawab, dan disiplin diuji hipotesisnya menggunakan analisis uji-t dengan bantuan program SPSS versi 20 for Windows. Hasil penelitian menunjukkan bahwa tidak ada perbedaan hasil belajar sikap yang signifikan antara kelompok siswa yang menggunakan model pembelajaran kooperatif NHT dan model pembelajaran kooperatif STAD dimana diperoleh nilai thitung ≤ ttabel (p>0.05) pada setiap indikator sikap. Kata kunci:      Model pembelajaran kooperatif NHT, model pembelajaran kooperatif STAD, hasil belajar sikap siswa.  ABSTRACT: This study aims to determine differences of student’s attitude learning outcomes between groups of students who receive NHT cooperative learning model and STAD cooperative learning model treatment for biology digestive system learning. This research was conducted at SMAN 2 Gerung in class of XI. This study is a quasi-experimental research using Type Between Group Design with Posttest Only Design. The number of population was 44 students consit of two classes, and all member of population used to sample study. By using simple random sampling obtained two classes of experiments. Data were analyzed using descriptive statistical and than with count the average of data, obtained scaling data and than hypothesis was tested using t-test analysis with SPSS version 20 for Windows. The results showed there was no significant difference about attitude learning outcome between the group the of students using NHT cooperative learning model and group of students using STAD cooperative learning model in all indicators of attitude that gained tcount ≤ ttable (p> 0.05). Key words:           NHT cooperative learning model, STAD cooperative learning model, student’s attitude learning outcome.

Abstract

The present research aims at knowing: 1) the influence of different concentration of diatom media fertilizer on the population density Tetraselmis sp.; 2) the influence of different concentration of KW21 fertilizer on the population density Tetraselmis sp.; 3) an optimal concentration of diatom media fertilizer and KW21 for the population density of Tetraselmis sp. An experimental with Completely Randomized Design was conducted by treating diatom media fertilizer and KW21 fertilizer. Each of the treatments was given concentration of 0%, 25%, 50%, 75%, and 100%. The results show that the concentration of diatom media fertilizer did give any significance influence on the population density of Tetraselmis sp. It could be seen from the value of Ftest which was lower than Ftable (23,05) > 3.48) at the significance level of 5%. The concentration of KW21 fertilizer had any significance influence on population density of Tetraselmis sp. by which the value of Ftest was 10,63 and the Ftable was 3.48 at the significance level of 5%. An optimal population density of Tetraselmis sp. fell on the treatment of A1B4C1 (94.83x105 cell/ml) and A2B4C1 (91.83x105 cell/ml).

Abstract

Butterflies play an important role in the ecosystem of Suranadi Natural Park in West Lombok. Butterflies help preserving the existence and diversity of flora by facilitating the process of pollination so it is crucial for flowering plants. The present study aimed at analyzing the diversity and determining the priority of butterfly conservation at Suranadi Natural Park of West Lombok. This exploration is a descriptive study. Data were observed in four-time repetition in the morning and in the afternoon for two months. The sweeping net technique following observation path was employed in this research (line left, line right,  line central and line waterway). The data analysis used the Shannon-Wiener diversity index and priority for conservation determined by Ministry of Forestry Regulation Number: P.57 / Menhut-II / 2008. Fourty (40) species of butterflies belonging to 5 families identified. The diversity index (H ) of butterflies ranges from 2.63 to 3.43 (medium-high). The two species of the Papilionidae family found at TWA Suranadi, namely, Troides helena and Papilio memnon were the priority of conservation. This research would be helpful to consider conservation strategy and ecotourism.

Abstract

ABSTRACTThe study of the effect of environment factors on amphibians there is no it in Lombok Island. This study aimed to analyze the environment factors that most contribute to the community structure of amphibians on the island of Lombok. Survey was conducted at 10 locations/points scattered on the island of Lombok. Both data of environment factors and community structure were collected on the square of 5000 m2 at each of the locations in the period from March to July 2016. The environment factors that the analyze including air temperature, water temperature, humidity, altitude, canopy, tree species richness, tilt, river length, width of the river and left-right width of the river to crawl. Amphibian community structure consists of species richness, density, species diversity, species evenness and dominance species. Data were analyzed using principal component analysis (PCA). The results show that environment factors that effect to the factor of the community can be divided into four components, namely component 1 (high effect), component 2 (middle effect), component 3 and component 4 (lower effect). Component 1 consists of humidity, canopy and tree species richness factor. Component 2 consists of air temperature, water temperature and altitude. 3 and 4 consist of a length of the river, the river width, the width of the river and tilt left and right.Key words: environment factors, structure of amphibian community, Lombok Island
