Abstract Purpose New environmental strategies are emerging for cities to become more self-sufficient, such as hydroponic crop production. The implementation of systems requires materials that usually originate in countries with low labour costs and other legal regulations. To what extent could these be shifting problems across the globe? answer this question, we performed a comprehensive social...

Musa acuminata stem is an agricultural waste that has good economic potential. For this reason, efforts are needed to increase the saba banana tree not only as waste, but also its function into natural fiber raw materials for polyester matrix composite reinforcement. The purpose of study was determine characteristics fibre (MASF) from North Lombok Regency, Indonesia Country a reinforcement comp...

We report a comprehensive investigation of the triple perovskite iridate Ba$_{3}$CoIr$_{2}$O$_{9}$. Stabilizing in hexagonal $P6_{3}/mmc$ symmetry at room temperature, this system transforms to monoclinic $C2/c$ magnetic phase transition. On further reduction partially distorts an even lower ($P2/c$), with both these structurally disparate phases coexisting down lowest measured temperatures. Th...

Coir fiber has been examined for their suitability as reinforcement of concrete. Mechanical properties and sustainability aspects concrete composites were estimated after 7. 14, 28 days curing. Natural 0.46 0.62% by weight coir was added. Fibers analyzed means scanning electron microscope (SEM). Besides, an Eco-audit tool used to estimate energy carbon emission material, manufacturing, transpor...

A large diameter triaxial sample of 61.9 mm was made by adding coir fiber into red clay. The range confining pressure 50–200 kPa; content 0.1%–0.4%; and length 10–40 mm. By varying the pressure, length, unconsolidated undrained tests were used to study shear strength variation law fiber-reinforced soil. experimental data processed establish a linear model segmental elastic modulus, analysis det...

Smoked fish is one of the processed products that are commonly found in Penatarsewu Village, Tanggulangin District, Sidoarjo Regency. a product has gone through smoking process. Fish food processing technology been known for long time. Smoking done by penetrating volatile compounds from burning wood [3] which can produce with specific flavors and aromas [4]. So far, production smoked carried ou...

There are many types of natural fiber including hemp, flax, jute, wood fiber, rice husks, straw wheat, oats, bagasse, barley, grass reeds, banana oil palm empty fruit bunch, coir, sisal, cotton, kenaf, ramie, water pennywort, paper-mulberry, kapok, abaca, pineapple leaf fiber. The production in India is 13.5 million tons per annual. Banana forming generates more quantity biomass which goes as w...

This study aims to make sheet organic mulch from several agricultural wastes and determine the best type of material for making mulch. research was carried out at Greenhouse Faculty Agriculture Laboratory Agrotechnology, Agriculture, Samudra University, Langsa City, Aceh Province which took place February April 2021.This used a non-factorial completely randomized design (CRD) with four replicat...
