“…The inhibition zone formed around the paper disk was measured for its vertical diameter and horizontal diameter in millimeters (mm). In this study, the isolation of silver nanoparticles was carried out by utilizing dragon fruit peel extract (H. polyrhizus) as a bioreductant through a maceration process using aquabidest solvent, because aquabidest was a good solvent for the extraction of compounds with low molecular weight such as flavonoids [1]. The skin of the dragon fruit (H. polyrhizus) used was the skin that fresh, not dry or rotten, the skin was still shiny, and the scales were still reddish pink.…”

“…Nanoparticles based on their composition can be divided into two types, namely organic and inorganic. Organic nanoparticles are carbon-based nanoparticles, while inorganic nanomaterials are composed of inorganic materials such as metals, magnetic materials and semiconductors [1,2]. One method of synthesizing nanoparticles that uses natural materials sourced from living organisms, such as plants, animals, and microorganisms that live on land or in the sea, as metal bio-redactors is the Green Synthesis Nanoparticle method.…”

This study examines the potential compounds dragon fruit peel extract (Hylocereus polyrhizus) which are synthesized into silver nanoparticles, then used as the antiseptic mouthwash. The synthesis process is carried out using the Green Synthesis Nanoparticle method, which utilizes natural materials as metal bioreductants due to it is more herbal and does not have a poisonous effect on health. Secondary metabolite compounds contained in dragon fruit peel extract (H. polyrhizus), namely flavonoid compounds functioned by donating electrons to Ag+ ions to produce silver nanoparticles that can be used as mouthwash because they are antimicrobial. Based on the results of the UV-Vis spectrum, the best nanoparticle synthesis results were obtained at the extract concentration of 0.25% for 30 minutes duration with a synthesis temperature of 70°C, which the absorbance peak of silver nanoparticles was obtained at wavelength of 444.5 nm, and visually changes the color of the solution to brown. Furthermore, based on the test results obtained from incubation for 24 hours, it was found that the mouthwash solution showed an inhibition zone on the two test bacteria. Escherichia coli bacteria produced an inhibition zone of 28 mm, while Staphylococcus aureus bacteria produced an inhibition zone of 25.5 mm.

“…Pengembangan nanopartikel merupakan solusi yang menjanjikan untuk mengurangi ketergantungan pestisida kimia sintetik dalam pengendalian penyakit cabai yang aman dan ramah lingkungan (Purnama et al, 2015). Sintesis nanopartikel dapat dilakukan menggunakan metode fisik dan kimia yang dapat menghasilkan nanopartikel murni, namun metode tersebut mahal karena membutuhkan surfaktan dan pelarut organik dalam jumlah banyak dan tidak ramah lingkungan (Fabiani et al, 2018). Teknologi sintesis nanopartikel yang berkembang beberapa tahun terakhir adalah green synthesis menggunakan kitosan sebagai reduktor, stabilisator dan donor elektron yang efektif, ramah lingkungan dan memberikan efek jangka panjang (Choudhary et al, 2017).…”

Wilt and anthracnose are diseases on chili that cause substantial losses and even crop failure. Control of the diseases is generally carried out using chemical pesticides which are environmentally harmful. Therefore, the development of nanoparticles, such as nanochitosan-Cu, can be an environmentally friendly solution in controlling chili disease. The current technology in developing nanochitosan-Cu is green synthesis, which uses an effective reducing agent but non-toxic for plants and the environment. However, the process requires sonication, which is difficult to be adapted for scale-up production. This research aimed to synthesize and determine the formulation of nanochitosan –Cuusing magnetic stirrer method without sonication, and also to evaluate the antifungal ability of nanochitosan-Cu againstFusarium oxysporum and Colletotrichum capcisi causing wilt and anthracnose disease, respectively. Synthesis of nanochitosan-Cu was carried out at 50°C and 400 rpm of speed. Characterizations of nanochitosan-Cu were analyzed using SEM-EDX and PSA. In vitro antifungal activity test was carried out by food poisoning method.The results showed that the synthesis of nanochitosan-Cu using ionic gelation method can be carried out without sonication process, and produce round shape nanoparticles with 183.7 nm of diameter. The nanochitosan-Cu was effective against F. oxysporum and C. capsici, at a concentration of 100 ppm. It inhibited the growth of F. oxysporum and C. capsici by 100% and 92.38%, respectively.Layu dan antraknosa merupakan penyakit pada tanaman cabai yang menimbulkan kerugian besar bahkan gagal panen. Pengendalian penyakit tersebut umumnya dilakukan menggunakan pestisida kimia yang tidak ramah lingkungan. Untuk itu perlu dikembangkan biofungisida yang ramah lingkungan, salah satunya adalah nanopartikel kitosan-Cu. Teknologi pengembangan nanopartikel yang saat ini sedang berkembang adalah green synthesis, yaitu menggunakan reduktor yang efektif namun tidak toksik terhadap tanaman dan lingkungan. Proses sintesis ini membutuhkan sonikasi yang cukup sulit untuk diadaptasi pada skala produksi masal. Penelitian ini bertujuan untuk melakukan sintesis nanopartikel kitosan-Cu dengan metode magnetic stirrer tanpa sonikasi, serta mengevaluasi kemampuan antifungi terhadap Fusarium oxysporum dan Colletotrichum capcisi penyebab layu dan antraknosa. Sintesis nanokitosan-Cu dilakukan pada suhu 50°C dengan kecepatan 400 rpm. Karakterisasi nanokitosan-Cu dilakukan menggunakan SEM-EDX dan PSA. Uji aktivitas antifungi secara in vitro dilakukan menggunakan metode peracunan makanan. Hasil penelitian menunjukkan bahwa sintesis nanokitosan-Cu dengan metode gelasi ionik dapat dilakukan tanpa proses sonikasi dan menghasilkan nanopartikel berdiameter 183,7 nm dan berbentuk bulat. Nanokitosan-Cu yang dihasilkan efektif sebagai antifungi terhadap F. oxysporum dan C. capsici. Pada konsentrasi 100 ppm, nanokitosan-Cu mampu menghambat pertumbuhan F. oxysporum dan C. capsici masing-masing sebesar 100% dan 92,38%.
