Abstract

Indonesia faces major environmental degradation challenges, so students’ interest in nature and environmental awareness are needed. Permaculture is an artificial ecosystem that promotes sustainable agricultural practice. Integrating permaculture into education can enhance students’ interest in nature and environmental awareness. However, a limited study has explored its practical application in educational settings. This study aims to examine the effect of permaculture integration in education on students’ interest in nature and environmental awareness, which can support the achievement of quality education according to SDG-4. This study used a quantitative approach with a quasi-experimental design. The instruments used were a scale to measure students’ interest in nature and essay tests to measure students’ environmental awareness. Data were analyzed using the Mann-Whitney U test (U = 0.28) and independent sample t-test (p = 0.40). The results showed that although there was no significant difference between the experimental and control groups regarding interest in nature and environmental awareness, this study is still important. Based on the scale of interest in nature, most students showed high emotional, cognitive, and value aspects. However, significant increases in environmental interest and awareness have not yet been achieved, indicating that permaculture-based learning requires a long-term period to provide a more tangible impact. It can be concluded that integrating permaculture into education can reinvent students’ interest and environmental awareness.

Abstract

The use of natural antioxidants for medicinal purposes deserves thorough attention for their efficacy and possibly adverse toxicity. This paper studies the antioxidant actions and toxicity effects of bark extracts. The study focuses on eleven tree species of Euphorbiaceae family. Initially, bark samples from those trees were extracted using ethanol. The acquired extracts were examined for peroxide values with iodometric method. The bark extracts were chemically screened for possible antioxidant-compound contents, i.e. polyphenols, flavonoids, and saponins; and followed by oxidation-reduction test to assess the extract ability in vitro to scavenge free radicals in their standard sources, i.e. 2,2-diphenyl-1-picrylhydrazyl; altogether to determine qualitatively which species origin from bark extracts afforded the most potential as antioxidants. Toxicity test was performed on those bark extracts to assess their safety on living creatures, particularly humans as tried on shrimp larvae by counting their death, using the Brine Shrimp Lethality Test method. Results show that bark extracts of four plant species, i.e. Acalypha hispida Blume, Bischofia javanica Blume, Glochidion arboreum Blume and Sapium baccatum Roxb species afforded potentiality as antioxidants, because its peroxide value (POV) was lower than or somewhat above those of the positive control vitamin E (POV 89.45 μg/ml). However, bark extracts from Euphorbia antiquorum L, Euphorbia hirta L, and Jatropha podagrica Hook (i.e. LC50 : 238.85; 228.11 & 194.51 μg/ml) were highly toxic, because their LC50’s value< 1000 μg/ml.

Abstract

Root and basal stem rot is one of important diseases in sugarcane plantations in South Sumatra and Lampung. This disease is caused by Xylaria sp. The study is aimed to determine the fungicides sensitivity of Xylaria sp. which is associated with root and stem rot disease of sugarcane. The Xylaria sp. was isolated from the stroma and diseased sugarcane stems obtained from PT Gunung Madu Plantations (GMP). The fungicides used were plant base fungicides (puyangan and jamuan) and synthetic fungicides (carbendazim, mancozeb, and chlorothalonil). The Xylaria sp. sensitivity test was carried out by the poison food technique. The doses used are; puyangan and jamuan (10 g/100 mL), carbendazim (2 g/L), mancozeb (3 g/L), and chlorothalonil (1 g/L). The rate of sensitivity change of Xylaria sp. on fungicides was test by subculturing the Xylaria sp. in media containing fungicides at a dose of 9 g/100mL (puyangan and jamuan), 0.1 g/L (carbendazim), and 0.5 g/L (mankozeb) three times. The results showed that the Xylaria sp. which is associated with root and basal stem rot disease of sugarcane is still very sensitive to fungicides puyangan, jamuan, carbendazim, and mancozeb at recommended doses, but is very resistant to chlorothalonil on 2x the recommended dose. The results of the rate of change in sensitivity of Xylaria sp. to fungicides showed that isolate A tended to change more quickly compared to isolate B and isolate C.

Abstract

Cockroach control should be based on Integrated Vector Pest Management connected to healthy food.  This research investigated the auto dissemination phenomenon from infected females to males by the mating process. The method used is a randomized design experiment with 4 treatments and 5 replications. The result showed that the auto dissemination effect occurred from infected females to males during the mating process. The highest concentration caused a higher effect while M. anisopliae has a potential effect to control effective and safe cockroaches.

Abstract

The sublethal effect of Blatella germanica infected with Metarhizium anisopliae, Beauvaria bassianna, and Spicaria on its offspring has been carried out. It is known that the LC50 value of each fungus is 106. This study aims to determine the extent of the sublethal effect on the duration of ootheca formation, the number of ootheca, and the number of ootheca produced. The ‘Dipping method’ was used with three treatments and five replications. The results showed that the sub-lethal effect influenced the duration of ootheca formation. Metarhizium anisopliae and Beauveria bassiana affected the start of ootheca formation when compared to the control (25.95 days), the length of time needed for ootheca that produced nymphs in Metarhizium anisopliae and Beauveria bassiana exposure compared to the control (6 days) and the number of nymphs caused by Metarhizium anisopliae and Beauveria bassiana produced fewer nymphs than the control (29.25 days).

Abstract

Biology learning requires a comprehensive understanding of concepts, including the relationships among organ structures, digestive processes, enzyme functions, and disorders of the human digestive system. This study aimed to analyze the effectiveness of descriptive feedback provided through Quizizz-based formative assessment in improving students’ conceptual mastery and learning motivation. A pre-experimental research design was employed, involving 33 Grade 11 science students from a public senior high school in Bogor City. Data on conceptual mastery were collected through tests administered for each subtopic, while learning motivation was measured using a five-point Likert-scale questionnaire administered before and after the intervention. The results showed that the attainment of the Minimum Mastery Criterion (KKM) was uneven across the subtopics. The subtopic of digestive system disorders or abnormalities significantly met the KKM, with a significance value of 0.000. In contrast, the subtopics of the structure and function of digestive organs, mechanical and chemical digestive processes, and the role of enzymes did not show significant attainment. The students’ mean conceptual mastery score was 81.03, with 60.61% of the students meeting the KKM and 39.39% not meeting it. Although the effectiveness based on the KKM was not statistically significant, students’ learning motivation increased significantly from 2.68 to 3.86 on a five-point Likert scale. Therefore, descriptive feedback provided through Quizizz can support students’ conceptual mastery and enhance their learning motivation, although its effectiveness based on the KKM remains uneven. Abstrak. Efektivitas feedback deskriptif otomatis dalam asesmen formatif berbantuan Quizizz menjadi fokus dalam penelitian ini, khususnya terhadap penguasaan konsep dan motivasi belajar siswa pada materi sistem pencernaan manusia. Penelitian dilaksanakan dengan metode pre-eksperimen menggunakan desain one-group pretest-posstest. Sebanyak 33 siswa kelas XI dari salah satu MA Negeri di Kota Bogor. Pengumpulan data dilakukan melalui tes penguasaan konsep serta angket motivasi belajar dengan skala Likert 5 poin. Data yang terkumpul dianalisis secara deskriptif dan inferensial, lalu dikaji berdasarkan ketercapaian Kriteria Ketuntasan Minimal (KKM). Temuan penelitian menunjukkan bahwa penggunaan feedback deskriptif otomatis melalui Quizizz pada asesmen formatif mampu meningkatkan penguasaan konsep dan motivasi belajar siswa. Hal tersebut terlihat dari kenaikan rata-rata skor penguasaan konsep pada setiap submateri. Meski demikian, jika mengacu pada Kriteria Ketuntasan Minimal (KKM), hasil peningkatan belum sepenuhnya optimal karena ketuntasan belum tercapai pada seluruh submateri. Rata-rata motivasi belajar siswa juga mengalami kenaikan, dari 2,68 menjadi 3,86. Pada skala Likert 1-5. Oleh karena itu, feedback deskriptif otomatis berbantuan Quizizz dapat dimanfaatkan sebagai alternatif untuk menunjang penguasaan konsep dan motivasi belajar siswa pada materi sistem pencernaan manusia.
