Abstract

Pembelajaran biologi saat ini memiliki masalah yang dimana ada beberapa siswa-siswi yang tidak menyukai mata pelajaran biologi disebabkan banyak hal baik dari murid, media, buku dan guru, yang di gunakan dalam pembelajaran biologi, permasalahan ini menyebabkan motivasi dan hasil belajar terpengaruh, Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Game based learning (GBL) berbantuan media Baamboozle terhadap motivasi dan hasil belajar biologi siswa kelas X SMA 2 Tenggarong Seberang. Penelitian menggunakan model penelitian quasi eksperimental, Penelitian ini akan dilaksanakan di SMA Negeri 2 Tenggarong Seberang selama Penelitian dilaksanakan dari bulan Februari-Mei 2024. Penelitian ini memberikan angket dan butir soal pre-test dan post-test.  didapat data hasil belajar yaitu pada kelas eksperimen rata-rata nilai 79,69. Kelas kontol 66,03, pada hasil angket motivasi diperoleh rata-rata dari kelas eksperimen 82,69 dan kelas kontrol 73,86, sehingga penerapan model pembelajaran Game based learning (GBL) berbantuan media baamboozle berpengaruh signifikan terhadap motivasi dan hasil belajar biologi siswa kelas X SMA 2 Negeri Tenggarong Seberang.

Abstract

Critical thinking skills are important for students, but not all students possess strong critical thinking abilities. This study aims to develop a STEM-EDP-based Student Worksheet media to improve students' critical thinking skills in the topics of Ecology and Biodiversity. This research uses the ADDIE development model, developed by Robert Reiser and Michael Molenda, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The developed media was validated by experts in content and media, with the media expert validation result being 91% and the content expert validation result being 94%, both categorized as highly valid. Practicality testing was obtained from practicality questionnaires filled out by both teachers and students. The student practicality questionnaire resulted in 90.5%, categorized as very practical, and the teacher practicality test resulted in 90%, also categorized as very practical. The effectiveness of critical thinking skills was assessed through pretest and posttest results, using the N-Gain test, which resulted in a score of 0.7, categorized as high. Therefore, it can be concluded that the use of STEM-EDP-based Student Worksheets to improve students' critical thinking skills is effective and categorized as high.

Abstract

Insect pest attacks are one of the main obstacles in cultivating striped spinach (Amaranthus tricolor L.), because they reduce the quality and quantity of the harvest. Long-term use of synthetic pesticides has a negative impact on the environment and health. This study aims to test the effectiveness of the combination of soursop leaf extract (Annona muricata L.) and garlic (Allium sativum) as a botanical pesticide on the intensity of pest attacks. The study was conducted using a Randomized Block Design (RBD) with five concentration treatments (0%, 25%, 45%, 65%, and 85%) and five replications. Data were analyzed using ANOVA and BNT test at the 1% level. The results showed that the botanical extract treatment had a significant effect on reducing the intensity of pest attacks, with a concentration of 85% giving the most effective results (Fcount 236.05 > Ftable 4.77). The treatment of plant leaves showed lower damage than the control. This effectiveness is thought to be due to the content of active compounds, such as flavonoids, saponins, tannins, acetogenins, and alkaloids which are toxic to pests. In conclusion, soursop leaf and garlic extracts have the potential to be environmentally friendly botanical pesticides and can be used as an alternative to control striped spinach plant pests.

Abstract

Cayenne pepper (Capsicum frutescens L.) is a horticultural commodity with high economic value that is widely consumed by the Indonesian people, but is susceptible to various types of pests, especially in the generative phase. This study aims to identify the type and dominance of insect pests that attack cayenne pepper plants in the generative phase in the farmland of Thousand Pinang Waterfall, North Sempaja Village, Samarinda. The research methods used include direct observation and insect collection using several types of traps (insect nets, light traps, and pitfall traps). Identification is carried out down to the family level with the help of a keybook of determination and morphological character of insects. The results of the study showed the existence of several insect pest families such as Tephritidae (fruit flies), Thripidae (thrips), Aphididae (aphids), and Bemisiidae (whiteflies) that were dominant during the generative phase of the plant. So it can be concluded that cayenne pepper plants in the generative phase in the farmland of the Thousand Pinang Waterfall, Samarinda, are vulnerable to being attacked by various types of insect pests. This is important to support a more precise and effective pest control strategy in the critical phase of the growth of cayenne pepper plants.
