Abstract

The use of slow-release or controlled-release fertilizers (SRF) is one effective approach to reducing nutrient loss. These fertilizers are designed to release nutrients at a controlled rate and time, aligned with the plant's needs. The nutrient release mechanism can be optimized by manipulating the physical or chemical properties of the fertilizer, involving processes such as diffusion, degradation, and hydrolysis. This study aims to analyze the effects of the mass ratio of zeolite and polyacrylic acid (PAA), as well as the influence of time and temperature during the coating process, on the characteristics of slow-release fertilizers (SRF). The goal is to produce SRF that minimizes negative environmental impacts and reduces costs compared to conventional fertilizers. By adjusting these parameters, it is expected that the resulting SRF will be more effective in gradually supplying nutrients to plants and offer a more economical solution than conventional fertilizers, which tend to deplete quickly or are lost through leaching.

Abstract

Daun kelor (Moringa oleifera), merupakan salah satu tanaman berkhasiat, salah satu manfaatnya sebagai anti inflamasi dan anti kanker karena menganduk senyawa aktif terutama flavonoid dan polifenol yang memiliki aktivitas sebagai anti oksidan. Kanker adalah penyakit yang timbul akibat pertumbuhan tidak normal sel jaringan tubuh yang mengalami mutasi genetik. Perubahan ini dapat disebabkan oleh tiga faktor utama yaitu faktor genetik, faktor gaya hidup dan faktor karsinogenik. Faktor karsinogenik disebabkan oleh stres oksidatif yang timbul akibat radikal bebas dan Reactive oxygen Species (ROS) yang dihasilkan oleh aktivitas metabolisme tubuh maupun paparan polutan dari luar tubuh. Untuk mencegah stres oksidatif, tubuh membutuhkan antioksidan yang adekuat. Daun kelor (Moringa Oleifera) memiliki kandungan antioksidan dan senyawa bioaktif yang tinggi sehingga berpotensi untuk mencegah terjadinya stress oksidatif dan kanker. Tujuan dilakukannya penelitian ini adalah untuk mengetahui nilai aktivitas zat antikanker (antioksidan) dalam ekstrak daun kelor dengan variasi pengeringan dan variasi waktu maserasi. Penelitian ini dilakukan dengan mengekstraksi daun kelor 100 gram hasil pengeringan menggunakan metode maserasi pelarut etanol 96% dengan variasi waktu maserasi 24,48 dan 72 jam. Hasil penelitian yang diperoleh dari satu sample dengan 3 variable waktu yang berbeda yaitu 24 jam diperoleh antioksidan 5,36%, 48 jam sebanyak 7,33% dan 72 jam sebesar 10,39%. Analisa atau uji aktivitas zat antikanker (antioksidan) dilakukan dengan metode HPLC. Hasil analisa menunjukan bahwa pada waktu maserasi 72 jam memiliki aktivitas antioksidan yang relatif lebih besar, karena menurut beberapa penelitian semakin lama waktu yang digunakan dalam pengujian maka semakin efektif zat yang dihasilkan tersebut.

Abstract

Anthocyanins are natural flavonoid pigments widely recognized for their biological activities, including antibacterial properties. Butterfly pea (Clitoria ternatea L.) flowers are known to contain significant levels of anthocyanins; however, the influence of extraction parameters on anthocyanin yield and their correlation with antibacterial activity remains limited. This study aimed to evaluate the effect of ethanol concentration (75%, 80%, and 90%) and maceration time (8, 16, and 24 hours) on total anthocyanin content of fresh butterfly pea flowers and to assess their antibacterial activity. Anthocyanin content was determined using the pH differential method with UV–Vis spectrophotometry at 510 nm and 700 nm. Extraction yield and physicochemical characteristics (pH, viscosity, and density) were also analyzed. The highest extraction yield (1.64%) was obtained using 75% ethanol for 8 hours, while the highest anthocyanin content (1.071 mg/100 g) was achieved with 80% ethanol for 8 hours, corresponding to absorbance values of 1.3425 (pH 1.0) and 1.3365 (pH 4.5). These results indicate that solvent polarity significantly influences anthocyanin extraction efficiency. However, antibacterial testing against Staphylococcus sp. showed only limited inhibition zones under all treatment conditions, suggesting that the extract concentration did not reach the minimum inhibitory concentration (MIC). Overall, while extraction parameters significantly affected anthocyanin content, increased anthocyanin levels did not directly correspond to significant antibacterial activity.
