“…berlanjut melalui proses untuk menghasilkan larutan perak, hal ini dikarenakan permukaan logam memiliki elektron bebas pada pita konduksi dan inti yang bermuatan positif. Untuk mereduksi larutan AgNO3 menjadi nanopartikel,reduktor atau agen pereduksi seperti Natrium borohidrida (NaBH4), unsur hidrogen, proses poliol, N,N-dimetilformamida (DMF), asam askorbat, poli(etilena glikol)-blok kopolimer, hidrazin, dan amonium format diterapkan untuk reduksi ion perak (Ag + ) dalam larutan (Esmaeilian et al, 2022;Zhu et al, 2020). Penelitian ini menggunakan ekstrak buah kiwi sebagai bioreduktor yang bertujuan untuk memperkecil ukuran nanopartikel dan menstabilkan ukuran nanopartikel perak.…”

“…Berdasarkan hasil karakterisasi dengan menggunakan instrumen PSA, ukuran sebaran AgNPs sekitar 65 nm. Pendekatan nanoteknologi berkaitan dengan desain, sintesis, dan manipulasi yang dilakukan untuk mendapatkan struktur partikel dengan ukuran berkisar antara 1-100 nm (Esmaeilian et al, 2022;Harsini et al, 2021;Kalwar & Shan, 2018;Zhu et al, 2020). Namun ketika larutan berubah warna menjadi abu-abu kehitaman dan dianalisis menggunakan PSA, data distribusi ukuran Ag sekitar 111 nm.…”

Green Synthesis or Green Chemistry of silver nanoparticles (AgNPs) has many advantages, one of which is fast, easy, and cheap. AgNPs have many benefits in the health sector. AgNPs are of great interest in the field of nanoparticle development because they have good biomedical and anti-bacterial activities. Bioreductors play an important role in reducing the size of AgNPs, in this study a natural bioreductor in the form of Kiwi extract (Actinida deliciosa) was used. Purpose of the study the objective of this research was the biosynthesis of AgNPs using a kiwifruit extract bioreductor. Research methods with extraction of Kiwi, synthesis of AgNPs using Kiwi extract, characterization of AgNPs formed using UV-Visible spectroscopy (UV-Vis), Fourier-transform Infrared Spectroscopy (FTIR), and Particle Size Analyzer (PSA). Research Results that AgNP formation was confirmed by optical performance using UV-VIS spectroscopy and showed an AgNP peak at 415 nm. The C-H, C-N, and C=O groups in Actinidia deliciosa were confirmed by FTIR. The size of the AgNPs was studied using PSA and a size of 65.01 nm was obtained.Abstrak: Sintesis Hijau atau Kimia Hijau nanopartikel perak (AgNPs) memiliki banyak keuntungan, salah satunya cepat, mudah, dan murah.

“…Biofertilizer proves to be as effective as mineral sources and provide ammonia in an environmentally friendly way [7]. Biofertilizers in developing and underdeveloped countries are slug and cow dung, containing beneficial microorganisms that improve soil quality and fertility [8]. The use of biofertilizers enhances crop productivity, which is crucial for the environment because of reduced dependency on chemical-based fertilizers [9].…”

The agriculture industry in the Western world is increasingly using biofertilizers, considering the environmental aspects and organic food. Sustainability in agriculture is the primary priority of the government of the Sultanate of Oman. In order to improve and develop the agricultural sector for community development, the government of Oman is paying special attention to its Vision 2040 in line with sustainable development goals. Hence, the aim of the research is to analyze the behavioral aspects of farmers and farmholders towards utilizing biofertilizers for saving the environment as well as providing organic food and bringing sustainability to the agriculture sector of the country. In order to meet the objectives of the study mixed method research has been used. An interview guide has been developed, a questionnaire has also been developed, and the instruments have been approved by the experts. The interview data were analyzed, and afterward, primary data were collected. To test the hypothesis and the framework, Smart PLS 3 has been used. The findings identified that farmers in Oman are reluctant to use biofertilizers because of a lack of awareness, but yet they are using it up to some extent and the proposed model has proven to be significant. The findings are useful not only for the policymakers but also for the practitioners who can obtain guidance about the benefits they can gain from the use of biofertilizers.

“…The application of the chemical fertilizers is one of the most important causes for the contamination of water, soil, air, and agricultural production [11]. Compared with chemical fertilization, the use of the bio -fertilizers and the solid wastes leads to an improvement in growth and yield of various crops such as medicinal and aromatic plants [12][13][14]. Furthermore, the application of an organic fertilizer is significant for the protection of the nature and the soil ecosystem [14].…”

Sage (Salvia officinalis L) is a widespread aromatic and medicinal plant with various positive affects in human diet and health. In order to investigate the interaction among bio-fertilization, plant density and irrigation regimes, in Salvia officinalis cultivation, an experimental field was established at the University Farm of Thessaly, in Velestino (Greece). The transplant was carried out in October 2016 and the experiment data concern the plant height, Leaf Area Index (LAI), Chlorophyll content and dry biomass of the 3 rd and 4 th growing years. A split-split-plot experimental design was used, including two irrigation regimes (IR0: no irrigation and IR1: irrigation), three bio -nitrogen fertilization systems (N0: 0 kg ha -1 , N1: 40 kg ha -1 , N2: 80 kg ha -1 ) and two different plant density (D1: 10.000 and D2: 20.000 plants ha -1 ). The use of the drip irrigation system ameliorated the plant height, the dry leaves yield and the LAI. The dry leaves yield in 3 rd year was ranged between 166.3 -522 kg ha -1 and 101.67 -359 kg ha -1 in May and August, respectively. As it concerns the Chlorophyll index (CCI), the bio -nitrogen fertilization and the irrigation had provoked an increase to its amount during the studied growing year. Therefore, Salvia officinalis can be a promising perennial crop, cultivated under the Greek climatic conditions.
