Abstract

This study aims to develop a booklet of types of natural orchids that are used as teaching materials on plantae material for junior high school students. The booklet contains pictures of the original types of orchids found in the Jorong Harapan Tinggam Community Forest, Talamau District, West Pasaman by describing the characteristics, morphology, classification, reproduction and role of orchids in life. The development of this booklet uses a 4-D model consisting of define, design, develop, and disseminate phase. The research carried out is only up to the develop stage, namely the validity test. This research was conducted in February 2022 at the PGRI Sumatera Barat University. The instrument used is a validity questionnaire, which be judged by of three validators, namely botanists, learning media experts and junior high school biology topics experts. The booklet validator includes three aspects of the assessment in terms of the feasibility of the content getting a score of 89%, the linguistic aspect is 87%, the didactic aspect is 86%, and the graphic aspect is 85%. The booklet that was developed as a whole got very valid results with a validation value of 86.75%.

Abstract

AbstractLearning outcomes of Animalia grade X of Senior High School required students to have the ability to group animals into phyla based on body layers, body cavities, and body symmetry as well as reproduction and relate their role in life. for the learning requirements of the Animalia topic to be identified, observations and analyses were carried out on the problems of teachers, students, tools, and learning facilities. This research is a descriptive study. The research instruments used were interview questionnaires, book content analysis questionnaires, and literature studies. the data obtained were analyzed descriptively. Based on the results of interviews with biology teachers, information was received that the availability of library textbooks was very lacking. From the results of the analysis of the contents of the book, it was found that the explanation has been separated by perphyla but has not explained the classification of Animalia, and has not included its role in life. Analysis of the curriculum content found that the school had used the 2013 revised 2018 curriculum but the learning objectives had not been described by KD 3.9. Based on the analysis results, it has to develop teaching materials that are to student requirements.

Abstract

This study aims to determine the success rate of hatching olive ridley turtle eggs (Lepidochelys olivacea) in semi-natural nests. This study used a descriptive method by direct observation of turtle eggs from conservation activists. The research was carried out in two locations, namely at the Jambak Sea Turtle Camp location, 3 nests of olive ridley turtle eggs (79 turtle eggs in the first nest, 81 turtle eggs in the second nest and 96 eggs in the third nest). The second location is at UPT Pariaman Turtle Conservation with 2 nests (first nest 100 turtle eggs, second nest 80 turtle eggs). The results showed that the hatching percentage of olive ridley turtle eggs in semi-natural nests at UPT Pariaman Turtle Conservation was 63.89%, at Jambak Sea Turtle Camp 40.63%. It can be concluded that allocating turtle eggs to semi-natural nests increases the hatching success of olive ridley turtle eggs (Lepidochelys olivacea).

Abstract

Penelitian bertujuan mengidentifikasi dan menganalisis keanekaragaman tumbuhan paku epifit pada tanaman kelapa sawit. Metode yang digunakan adalah metode observasi dan identifikasi langsung serta studi pustaka. Teknik pengambilan sampel menggunakan Metode Slovin. Penelitian dilakukan di kebun rakyat di Nagari Gunung Selasih, Kecamatan Pulau Punjung Kabupaten Dharmasraya. Penelitian dilaksanakan dari bulan September-November 2017. Dari penelitian yang telah dilakukan maka dihitung nilai Kerapatan Relatif, Frekuensi Relatif, Indeks Nilai Penting (INP) Dan Keanekaragaman Shannon Wiener. Dari hasil identifikasi ditemukan 16 spesies paku epifit. Spesies dengan kelimpahan tertinggi yaitu G. Verrucosum. Indeks Nilai Penting (INP) paku epifit tertinggi terdapat pada spesies G. verrucosum. Berdasarkan hasil perhitungan Indeks Shannon-Wiener menunjukkan bahwa tingkat keanekaragaman paku epifit pada tanaman kelapa sawit berada dalam kondisi yang rendah (0,85).

Abstract

Tujuan penelitian menganalisis efek penambahan dosis getah aren (nira) dengan kosenstrasi berbeda terhadap daya tetas telur ikan gurami, menganalisis pengaruh penambahan dosis nira aren dengan kosenstrasi berbeda terhadap kelangsungan hidup larva ikan gurami, menganalisis pengaruh penambahan dosis nira aren dengan konsentrasi berbeda terhadap pertumbuhan. Penelitian dilakukan selama 21 hari, dimulai dari telur sampai larva. Penelitian dilakukan dengan metoda eksperimen yaitu 4 perlakuan, 3 kali ulangan, dianalisis dengan menggunakan metoda one way ANOVA. Hasil penelitian uji deskriptif dihasikan rata-rata daya tetas gurami tertinggi pada perlakuan C (99,00 %), diikuti perlakuan D (98,66%), B dan A (93,33%), Pada uji homogenitas dinyatakan bahwa nilai p>0,05 (0.477>0,05) yang artinya data yang diuji homogen, dan dilihat pada uji one way ANOVA didapat nilai p>0,05 (0,373>0,05), jika sig >0,05 maka H0 diterima yang artinya tidak terdapat perbedaan nyata terhadap pemberian perlakuan yang berbeda pada berat larva gurami.

Abstract

This research aims to determine the influence of WhatsApp Group-based Blended Learning on students' critical thinking abilities. The study adopts a quasi-experimental design and is conducted at SMAN 8 Seluma. The sample consists of Class XII MIPA 1 as the experimental group receiving blended learning treatment, and Class XII MIPA 2 as the control group undergoing conventional learning. The Statistics Group Pretest-Posttest design is employed. Non-Probability Sampling is used for sample selection, and data analysis is performed using the t-test. The research findings reveal a significant difference in students' critical thinking abilities between the experimental and control groups. The average critical thinking ability score for the experimental group is 49.55, while for the control group, it is 46.43. The t-test results indicate a significance level of Sig. (2-tailed) = 0.000 < 0.05, and Tcount (calculated t-value) = 5.668 > Ttable (critical t-value) = 2.022 (sig: 5.668 > 2.022). Therefore, H1 is accepted, and H0 is rejected, leading to the conclusion that WhatsApp Group-based Blended Learning has a significant influence on students' critical thinking abilities.
