Abstract

Introduction. Black potato (Plectranthus rotundifolius) is one of the tubers in Indonesia and not well known by the public. It causes inadequate use of black potato than any other tubers. The parts that are currently used are the potato flesh. Meanwhile, the black potato peels are not used. Although the black potato peels contain polyphenol saponins, flavonoids, and antioxidant compounds. Method. Phytochemicals can be separated using extraction methods, one of the modern extraction methods used is the ultrasonic bath method. The ultrasonic bath method is a method that uses ultrasonic waves with a frequency greater than 16-20 KHz. The objective of this research is to determine the phytochemical content and antioxidant activity of lowland black potato peels with cow manure using ultrasonic bath extraction method. The research was conducted experimentally using RAL (Completely Randomized Design) with 3 factors and 3 replications, which included the difference in extraction temperature (55°C); extraction time (15 and 20 minutes); and the ratio of materials and solvents (1:5 and 1:10). Results & Analysis.The data obtained were yield, total phenolics, total tannins, flavonoids and antioxidant activity of black potato peels extracted using ultrasonic bath method with different temperature, extraction time and solvent ratio. The data obtained were analyzed using the Anova test with a significance of α = 0.05. Discussion. The analysis indicated that the treatment of 5 kg/plot manure with an extraction time of 20 minutes, at a temperature of 55°C, and a ratio of ingredients and solvents is 1:10 provided the best quality at 4.13% moisture content, 17.90% yield, 0.177 g/g phenols total, 0.063 g/g tannins, 0.096 g/g flavonoids and 45.275 ppm antioxidant activity.

Abstract

The use of fly ash and bottom ash as a plant medium can reduce waste from burning coal. The ash waste contains micro and macro nutrients that plants can use for growth. The ash contains the elements Na, K, Ca, Mg, Cu, Zn, and MN. This research aims to determine the effect of fly ash, bottom ash, and their combination on the growth of tomato plants (Solanum lycopersicum). This research used RAL (Completely Randomized Design) with 12 factors and 3 replications, namely k0 (negative control, not given anything), k1 (positive control, given urea fertilizer), a1 (400 g/polybag fly ash), a2 (800 g/polybag fly ash), a3 (1200 g/polybag fly ash), b1 (400 g/polybag base ash), b2 (800 g/polybag base ash), b3 (1200 g/polybag base ash), ab1 (200 g/polybag fly ash + 400 g/polybag fly ash), ab2 (400 g/polybag fly ash + 200 g/polybag fly ash), ab3 (600 g/polybag fly ash + 400 g/polybag fly ash), and ab4 (400 g/polybag fly ash + 600 g/polybag fly ash). The observation variable is the growth of tomato plants, including plant height, number of leaves, number of branches, stem diameter and wet weight. The results showed that there was an effect of using fly ash and bottom ash as a planting medium on the growth of tomato plants for 90 DAP in the AB4 treatment. The combination of 400 g/polybag fly ash + 600 g/polybag fly ash gave good results in plant height, number of leaves, number of branches, and fresh weight of tomato plants, but in terms of branch diameter, NPK treatment gave good results.

Abstract

Kegiatan pembakaran batu bara di PLTU menyisakan limbah dalam jumlah besar setiap tahunnya. Pembakaran batu bara menghasilkan sekitar 5% polutan padat berupa fly ash (abu terbang) dan bottom ash (abu dasar). Unsur hara lain dalam abu batubara yang dibutuhkan dalam tanah untuk tanaman antara lain B, P, dan unsur-unsur seperti Cu, Zn, Mn, Mo, dan Se. Penelitian ini bertujuan untuk mengetahui pengaruh abu terbang, abu dasar dan kombinasinya terhadap hasil panen dan kandungan fitokimia tanaman tomat (Solanum lycopersicum). Penelitian ini dilakuan di Green House Program Studi Biologi Fakultas Sains dan Teknologi Universitas PGRI Adi Buana Surabaya pada bulan Januari hingga Mei 2024. Penelitian dilakukan secara eksperimental deangan menggunakan RAL (Rancangan Acak Lengkap) dengan 12 faktor dan 3 ulangan yakni k0 (kontrol, tidak diberi apapun), k1 (kontrol positif, pemberian pupuk urea), a1 (400 g/polybag abu terbang), a2 (800 g/polybag abu terbang), a3 (1200 g/polybag abu terbang), b1 (400 g/polybag abu dasar), b2 (800 g/polybag abu dasar), b3 (1200 g/polybag abu dasar), ab1 (200 g/polybag abu terbang + 400g/polybag abu dasar), ab2 (400 g/polybag abu terbang + 200 g/polybag abu dasar), ab3 (600 g/polybag abu terbang + 400 g/polybag abu dasar) dan ab4 (400 g/polybag abu terbang + 600 g/polybag abu dasar). Parameter pengamatan yang diamati meliputi hasil panen (jumlah buah, bobot buah dan diameter buah) serta kadar fitokimia (flavonoid dan antosianin). Data yang didapat dianalisis menggunakan uji Anova dengan signifikansi α = 0,05. Hasil penelitian menunjukkan perlakuan ab4 yang merupakan kombinasi 400 g/polybag abu terbang + 600 g/polybag abu dasar memberikan hasil yang baik pada parameter hasil panen yaitu berat buah dan diameter buah dan serta kadar fitokimia tanaman tomat.
