Abstract

Daging entok memiliki tekstur yang berlemak (juicyness) dan sangat gurih. Terdapat beberapa kelemahan yang ada dalam daging entok yaitu daging entok memiliki tekstur yang lebih keras dibandingkan dengan daging yang berasal dari unggas lainnya. Berdasarkan penelitian terdahulu yang telah dilaksanakan kami mempunyai inovasi yaitu menerapkan penambahan ekstrak buah papaya terhadap daging entok dengan cara pemasakan yang diharapkan dapat meningkatkan kualitas daging entok menjadi lebih diminati oleh masyarakat Indonesia dengan kategori warna lebih segar dan tingkat kesukaan konsumen meningkat. Penelitian ini dilakukan pada Tanggal 11 Bulan Januari 2025 – 12 Februari 2025 di Laboratorium Terpadu Universitas Ma’arif Nahdlatul Ulama Kebumen. Bahan yang digunakan meliputi daging entok segar sebanyak 20 kg, yang diambil dari bagian dada entok betina berumur 6 bulan yang didapatkan dari KTT Sumber Baru Jatisari Kebumen. Penelitian menggunakan metode Racangan Acak Lengkap (RAL) dengan menggunakan 5 perlakuan dan 4 ulangan. Perlakuan yang diberikan yaitu sebagai kontrol (P0 = 5 kilogram daging entok tanpa penambahan ekstrak papaya), (P1 = 5 kg daging entok + 250 ml ekstrak pepaya), (P2 = 5 kilogram daging entok + 500 ml ekstrak papaya), (P3 = 5 kilogram daging entok + 750 ml ekstrak papaya) dan (P4 = 5 kilogram daging entok + 1000 ml ekstrak papaya). Data mengenai kualitas rasa dan warna diolah menggunakan analisis sidik ragam (ANOVA) satu arah. Hasil penelitian yang telah dilaksanakan ditemukan pengaruh signifikan (P<0,05) di antara perlakuan, selanjutnya dianalisis dengan metode Kruskal-Wallis dengan bantuan media digital berupa software IBM SPSS versi 26. Hasil analisis efektivitas penambahan ekstrak buah papaya terhadap kualitas rasa dan warna daging entok memperlihatkan pengaruh yang signifikan P>0,05 terhadap tingkat kesukaan panelis pada daging entok, perlakuan P4 pada variabel rasa memperoleh nilai rata-rata tertinggi sebesar 4.8, dengan kategori "Sangat suka". Perlakuan P2 pada kualitas warna menunjukkan peningkatan nilai rata-rata menjadi 3.7, yang termasuk dalam kategori warna "Agak Pucat – Merah”.

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

Creativity skills are one of the essential skills to face the VUCA World. Improving creativity skills is hampered by the large number of students and learning conditions that are less demanding of the creative process in the class. This research aims to measure the effectiveness of the Botanical Eco-gamification program to improve creativity skills. The ADDIE research approach was used to redesign the Botanical Eco-gamification program so that it can improve creativity skills. This research produced test instruments, e-LAD and questionnaires to measure creativity skills in the program. The instrument developed has been proven valid and reliable for measuring originality, divergent thinking, convergent thinking and mental flexibility skills. The results of program implementation show that students' creativity skills have increased from before treatment in the sufficient category (54.2) to the good category (71.16) with the N-Gain achievement being categorized as medium (0.37). The majority of students (55.71%) reached mastery level after being given treatment. Almost all students (76.29%) stated that the program was good for improving creativity skills. Further research is needed to examine other 4cs competencies, ESD competencies, mastery learning and student's engagement in the Botanical Eco-gamification program

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.
