Abstrak. Larutan Hara AB Mix merupakan pupuk majemuk campuran larut air yang sering digunakan pada sistem media hidroponik. Efektifitas ini sebagai sumber hara bagi tanaman sayur antara lain dipengaruhi oleh konsentrasi pemberian tepat. Percobaan dilakukan di dalam polybag menggunakan rancangan acak lengkap (RAL) terdiri atas 5 perlakuan larutan yaitu: 0,25; 0,50; 0,75; 1,00; dan 1,25 g L-1 den...

Novel and more sustainable sound absorbing materials are produced through the valorization of waste biomass sources by following circular economy principles. Cellulosic nanocrystals (CNC) were extracted from Posidonia oceanica dead leaves, spent barely grains, kale stems (KS) using a simplified purification protocol. These used to prepare cellulosic aerogels, evaluating effect three parameters,...

Three new genera, six species, three combinations, epitypes, and 25 interesting host /or geographical records are introduced in this study. New genera: Neoleptodontidium (based on aquaticum ), Nothoramularia ragnhildianicola ). species: Acremonium (from cooling pad water, USA, Cladophialophora laricicola (on dead wood of Larix sp., Netherlands), Cyphellophora neerlandica lichen brick wall, Geon...

This study aims to the interaction between catfish populations and type of growing media on growth yield spinach (Amaranthus sp.) Cultivated by aquaponics system. research was conducted using an experimental method (experiment), from July August 2020 in area PUSKOPAD complex, Tanjungsari District, Sumedang Regency. at altitude 850 m above sea level. The design used Split Plot Design with basic ...

New materials are increasingly used in the construction of cold-formed Light gauge Steel Frame (LSF) systems to achieve lightweight, more durable and fire resistant building systems. However, these being without good knowledge understanding their elevated temperature thermal properties. Hence a thorough investigation properties was conducted for range LSF Australia, Zealand Europe. Thermal prop...

The nutrient replenishment method primarily impacts the variations in a closed-loop soilless culture system. However, there is still lack of systematic approaches for effective way replenishment. Our previous study theoretically derived and experimentally validated an alternative expecting synchronized total fertilizer supply to absorption by crops lower concentration fluctuations than conventi...

Wheatgrass microgreen is commonly ingested as juice, which high in vitamins, minerals, enzymes, and chlorophyll. The purpose of this study was to see how different liquid fertilizers affected the growth quality, wheatgrass when planted types planting media., Factorial Randomized Block Design used study, with two factors: fertilizer treatment factor (P1 = Eco Enzyme 15ml/1L, P2 =Liquid Organic F...
