Abstract

The research on Odonata diversity was conducted in Antapani, Cigadung, Dago Pakar and Dago Pojok paddy fields located in Bandung. The objectives of the study were to identify Odonata species, to analyse the population dynamics and abundance of Odonata. Adults of Odonata were taken by sweeping net (depth 60 cm, Ø 30-38 cm), and nymphs were caught by sieve of the size of Ø 30 cm. The samples were done taken paddy growth. Adults. Two (2) families of adult Odonata were identified and consist of 4 species, i.eOrthetrum sabina (Libellulidae), Crocothemis servilia (Libellulidae), Neurothemis terminata (Libellulidae) and Anaciaeshna jaspidea (Aeshnidae). Three (3) species of nymphs Odonata were identified, i.e: Orthetrum sabina (Libellulidae), Crocothemis servilia (Libellulidae), and Anaciaeshna jaspidea (Aeshnidae). The result of this research showedthat Crocothemis servilia (Libellulidae) and Orthetrum sabina (Libellulidae) were dominant species in four research location. In the early  paddy growth (vegetatif phase to pregnant phase ~ 22 - 27 day) showed the highest number of Odonata (adult and nymph) compared with the other phase, by the time there will be a decrease in the population of Odonata. The sex ratio on adult Odonata show that male Odonata is more biggestthan Odonata female. The highest lenght of odonata nympha at vegetative and  primodial phase at the first stage of paddy growth and the lowest lenght at bunting, masak susu and masak penuh phase. Keywords : Odonata, Sex Rasio, Body Lenght (Instar)

Abstract

LKPD digunakan sebagai suatu bahan ajar yang dapat membantu dan mempermudah dalam proses pembelajaran. Penelitian ini bertujuan untuk mengetahui struktur, kelayakan dan kepraktisan LKPD berbasis SSCS (Search, Solve, Create and Share). Metode penelitian yang digunakan adalah R & D dengan model Borg & Gall. Subjek penelitian adalah Guru dan 29 orang peserta didik kelas XI SMA Negeri 01 Kota Bengkulu. Hasil penilaian validasi keseluruhan aspek pada bahan ajar LKPD Biologi berbasis SSCS materi sistem pernapasan yang dikembangkan memiliki kelayakan sangat baik dengan persentase 86,41%. LKPD yang dikembangkan dikategorikan sangat praktis, semua aspek penilaian yang diberikan melalui lembar respon peserta didik mendapatkan hasil dengan persentase 100%, peserta didik memberikan respon yang baik terhadap LKPD yang dikembangkan. Hasil belajar peserta didik menunjukan bahwa LKPD Biologi berbasis SSCS mampu memfasilitasi pengetahuan faktual, konseptual dan prosedural peserta didik dengan memperoleh persentase sebesar 92.09%.

Abstract

 AbstrakPenelitian ini bertujuan untuk menganalisis keanekaragaman makroinvertebrata di Sungai Kampai, Bengkulu. Pengambilan sampel dilakukan di tiga stasiun, yaitu Muara Simpur, Pagar Agung, dan Lubuk Gio dengan dua kali periode sampling setiap stasiun, yaitu April 2019 mengikuti puncak musim hujan dan September 2019 mengikuti puncak musim kemarau. Pengambilan sampel makroinvertebrata menggunakan metode three minutes sampling. Hasil penelitian ditemukan 501 individu makroinvertebrata yang terdiri dari 25 spesies (24 genus; 22 famili; 5 kelas; 4 filum). Epeourus aculeatus merupakan spesies dengan kelimpahan relatif tertinggi secara keseluruhan, yaitu sebesar 62,08%. Indeks keanekaragaman (H’) berturut-turut adalah 1,72; 1,13; 1,80 mengindikasikan bahwa Sungai Kampai mengalami degradasi ringan. Jumlah individu Ephemeroptera, Plecoptera, dan Trichoptera (EPT)  per stasiun dari hulu ke hilir adalah 128; 196; dan 20 dengan Indeks Biotik Famili (IBF) adalah 3,34; 4; dan 4. Berdasarkan gabungan dari beberapa indeks ini menunjukkan bahwa kondisi Sungai Kampai masih tergolong sangat baik.AbstractThis research aims to analyze macroinvertebrate diversity in the Kampai River, Bengkulu. Sampling was carried out at three stations, namely Muara Simpur, Pagar Agung, and Lubuk Gio with two sampling periods for each station, namely April 2019 following the peak of the rainy season and September 2019 following the peak of the dry season. Macroinvertebrate sampling used the three minutes sampling method. The research results found 501 macroinvertebrate individuals consisting of 25 species (24 genera; 22 families; 5 classes; 4 phyla). Epeourus aculeatus is the species with the highest relative abundance overall, namely 62.08%. The diversity index (H') is 1.72; 1.13; 1.80 indicates that the Kampai River is experiencing mild degradation. The number of Ephemeroptera, Plecoptera and Trichoptera (EPT) individuals per station from upstream to downstream is 128; 196; and 20 with a Biotic Family Index (IBF) of 3.34; 4; and 4. Based on a combination of several indices, it shows that the condition of the Kampai River is still considered very good.
