Abstract

Penelitian ini bertujuan untuk mengetahui kandungan C, N, P, dan K; mengetahui pengaruh pemberian POC terhadap pertumbuhan tanaman bayam merah; dan mendapatkan kombinasi konsentrasi dan frekuensi POC terbaik. Penelitian ini menggunakan RAL yang terdiri dari 2 faktor. Faktor pertama frekuensi POC (F1=4 hari sekali, F2=8 hari sekali), dan faktor kedua konsentrasi (P0=0 ml/L, P2=20 ml/L, P3=40 ml/L). Analisis data menggunakan two-way anova dan uji lanjut duncan untuk data yang normal dan homogen. Data yang tidak normal dan homogen diuji kruskal-wallis dan uji lanjut mann-whitney. Selanjutnya dilakukan uji regresi linier berganda. Hasil penelitian terbaik parameter tinggi tanaman 43,00 cm, diameter batang 8,05 mm, jumlah daun 41,75 helai, panjang akar 10,15 cm, berat basah akar F1P2 2,08 gram, berat basah batang 14,56 gram, berat basah daun 11,18 gram, berat kering akar 0,34 gram, berat kering batang 3,56 gram, dan berat kering daun 1,37 gram. Kesimpulan penelitian ini POC Azolla microphylla dan kulit pisang belum sesuai Permentan No 70 Tahun 2011. Konsentrasi dan frekuensi pemberian POC berpengaruh terhadap semua parameter pertumbuhan kecuali tinggi tanaman, diameter batang, dan berat kering batang bayam merah. Pemberian POC 4 hari sekali dengan konsentrasi 20 ml/L merupakan perlakuan terbaik

Abstract

Avocado plants (Persea americana Mill.) are widely grown in tropical and subtropical regions. Avocado leaves contain natural antioxidants for traditional medicine. This study aims to determine the total phenolic content, total flavonoids, and antioxidant activity values of young and old avocado leaves, and analyze the relationship between total phenol content and total flavonoids to the antioxidant activity value of avocado leaf methanol extract (Persea americana Mill.). The macerated avocado leaf extract was quantitatively tested for antioxidant activity using the DPPH method and the total phenolic and flavonoid contents were calculated using the Follin-Ciocalteu and Follin-Ciocalteu methods, respectively.The results showed that the highest total phenolic content of old avocado leaves was 1.682,27mg GAE/100g dry weight. The highest total flavonoid content of avocado old leaves was 3.858,96mg QE/100g dry weight. Antioxidant activity of methanol extract of young avocado leaves has a value of IC50 321.32 ± 80.43 ppm and avocado old leaves amounted to 288.54 ± 33.06 ppm. Total flavonoid content was more influential on antioxidant activity, with a correlation coefficient of 0.856

Abstract

Household organic waste management in densely populated areas such as Tegalrejo, Yogyakarta, poses a significant challenge that impacts both environmental quality and public health. This community service program aimed to enhance the knowledge and skills of local residents—particularly members of the PRA Tegalrejo women's group—in utilizing Black Soldier Fly (BSF) larvae, or maggots, as biological agents for organic waste decomposition. The training was conducted through educational sessions, live demonstrations on maggot utilization, and interactive discussions. The results showed a 14.73% increase in participants’ understanding, based on pretest and posttest scores. Participants not only gained knowledge about the decomposition process using maggots, but also recognized the potential of maggot farming as a source of animal feed and local economic opportunity. This program demonstrates that hands-on, eco-friendly education can effectively encourage community participation in waste management while simultaneously strengthening environmental resilience and household socio-economic sustainability.
