ABSTRACTThe research aims to utilizing interaction earthworm with environment in the calcareous land. The research can be specified through a two-stage: the first year and second year. Results from our earlier studies aims: (1) to find out earthworm interaction with calcareous land, (2) identification of earthworm in calcareous land. Using three examples from different land: monoculture, polyculture, and agroforestry. The research data collected with 3 repetitions in every land. Measurement of micro climates include temperature, humidity, pH, and light intensity. Identification the type of earthworm consist of: the body shape, color, position and the form of klitelum, the prostomium, setae, and the position of genetal males and females. Identification using binocular microscopy at 10 to 40x magnification. Analysis correlation were tested to figure out the relationships between variables. If the correlation of relationship between variable is very real or real continued test by STEPWISE REGRESSION to find out the most influential environmental factors on earthworms living. The result of the research are: (1) Earthworm had very significant most correlation (significant = 0,01) with air humidity (r= 0,855), light intensity (r = - 0,825), and soil humidity (r = 0,60). Other environmental factors had a significantly small influence (pH, r =0,17; soil temperature, r = - 0,28; and temperature r = 0,03). Air humidity is the most influential environmental factors on earthworms living (2) identification of the types earthworm in different three land was found 2 species: Pontoscolex corethrurus and Metaphire javanica. In monoculture land is dominated by Metaphire javanica, whereas in Polikultur and Agroforestry land is dominated by Pontoscolex corethrurus. As a result, air humidity is the most influential environmental factors on the lives of earthworms and other environmental factors is relative small influence. On the calcareous land found two species of earthworm: Pontoscolex corethrurus and Metaphire javanica.

AbstrakPenelitian bertujuan untuk mengetahui pengaruh media pembelajaran berbasis Articulate Storyline terhadap motivasi dan kepuasan belajar, serta efektivitasnya pada pembelajaran daring. Metode yang digunakan adalah Quasi-Experimental, desain penelitian Pretest-Posttest Nonequivalent Control Group Design. Sampel penelitian siswa kelas XI MIPA 2 dan XI MIPA 6. Pengumpulan data melalui observasi, wawancara, dokumentasi, angket motivasi dan kepuasan belajar, tes kognitif. Uji hipotesis menggunakan Manova untuk mengetahui adanya pengaruh, uji regresi untuk mengetahui sejauh mana pengaruh, dan uji N-Gain untuk mengetahui efektivitas media. Hasil uji Manova menunjukkan nilai sig 0,00 0,05 sehingga H0 ditolak. Hasil uji regresi aspek motivasi belajar: hasrat mencapai keberhasilan (17,16%), dorongan dan kebutuhan belajar (15%), cita-cita masa depan (15,61%), penghargaan dalam proses belajar (12,65%), kegiatan yang menarik dalam belajar (21,68%), dan lingkungan belajar yang kondusif (17,92%) . Hasil uji regresi aspek kepuasan belajar: tangible (29,56%), assurance (16,33%), empathy (23,68%), reliability (24,37%), dan responsifeness (5,94%). Hasil N-Gain 68,44%. Dapat disimpulkan bahwa ada pengaruh media terhadap aspek motivasi dan kepuasan belajar, serta efektivitas media pembelajaran berbasis Articulate Storyline berada di kategori cukup efektif (sedang) terhadap motivasi dan kepuasan belajar siswa.AbstractThis study aims to determine the effect of Articulate Storyline-based learning media on learning motivation and satisfaction, as well as its effectiveness in online learning. The method used is Quasi-Experimental, the research design is Pretest-Posttest Nonequivalent Control Group Design. The sample was students of class XI MIPA 2 and XI MIPA 6. Collecting data through observation, interviews, documentation, questionnaires motivation and learning satisfaction, cognitive tests. Hypothesis testing using Manova to determine the effect, regression test to determine the extent of the effect, and N-Gain test to determine the effectiveness of the media. The results of the Manova test showed a sig value of 0.00 0.05 so that H0 was rejected. Regression test results of learning motivation aspects: desire to achieve success (17.16%), motivation and learning needs (15%), future aspirations (15.61%), appreciation in the learning process (12.65%), activities interesting in learning (21.68%), and a conducive learning environment (17.92%). The results of the regression test for learning satisfaction aspects: tangible (29.56%), assurance (16.33%), empathy (23.68%), reliability (24.37%), and responsiveness (5.94%). The N-Gain result is 68.44%. It can be concluded that there is an effect of media on aspects of motivation and learning satisfaction, and the effectiveness is in the category of being quite effective (medium) on motivation and learning satisfaction.

Analisis Ketuntasan Hasil Belajar Kognitif Peserta Didik di SMA Negeri 1 Karas Tahun Pelajaran 2017/2018 pada Mata Pelajaran Biologi Ditinjau dari Profil Pemenuhan Standar Nasional Pendidikan dan Proses Pembelajaran Irwan Irwan; Maridi Maridi; Sri Dwiastuti

Penelitian ini bertujuan untuk mengetahui ketuntasan hasil belajar kognitif peserta didik pada mata pelajaran biologi ditinjau dari profil pemenuhan standar nasional pendidikan dan proses pembelajaran yang dilakukan di SMA Negeri 1 Karas tahun pelajaran 2017/2018. Metode penelitian yang digunakan adalah metode penelitian deskriptif dengan pendekatan kualitatif melalui observasi, penyebaran angket, dan wawancara langsung dengan guru dan peserta didik. Teknik pengambilan sampel dalam penelitian ini dilakukan dengan simple random sampling. Hasil penelitian menunjukkan persentase pemenuhan 8 standar nasional pendidikan di SMA Negeri 1 Karas sebesar 81,48%. Hasil analisis Ujian Nasional selama tiga tahun terakhir pada mata pelajaran biologi menunjukkan bahwa terjadi penurunan nilai rerata penguasaan materi tingkat mata pelajaran biologi selama tiga tahun terakhir yaitu tahun 2015 sebesar 77,69 menurun di tahun 2016 menjadi sebesar 67,16 dan penurunan nilai rerata penguasaan materi biologi peserta didik berlanjut di tahun 2017 sebesar 56,04. Hasil angket proses pembelajaran yang dilakukan di sekolah menurut guru telah mencapai 83,3% dan menurut peserta didik mencapai 65,7%. Pembelajaran yang dilakukan oleh guru sudah dilakukan sesuai dengan standar pelaksanaan kurikulum yang diterapkan di sekolah yaitu melalui pendekatan saintifik. Proses pembelajaran yang dilakukan oleh guru menurut peserta didik sudah baik, namun perlu dikembangkan dan ditingkatkan agar hasil belajar kognitif peserta didik meningkat dan lebih bagus dari sebelumnya
