Cucumber production has decreased in recent years. Several ways to increase cucumber productivity are the application of organic fertilizers and using appropriate varieties. Coconut coir is one wastes from rest coconut fruit that potential be utilized because it easily obtained large quantities easy process as liquid fertilizer. The aim research was study responses growth yield three (Cucumis s...

Greenhouse tomato growers in the United States have few products available for chemical control of plant pathogens. Biological control of soilborne plant pathogens by antagonistic microorganisms is a potential alternative to the use of chemical pesticides during greenhouse production. Biological control experiments were conducted to test the effects of commercial and noncommercial strains of Tr...

The demand for natural fiber-reinforced sustainable products is increasing continuously worldwide. technology to produce lignocellulosic cementitious materials currently limited; hence, new routes composite development are being explored. current study presents an innovative semi-dry implemented on material (coir fiber and Scots pine particle) reinforced panels. Composite panels of 12 mm thickn...

This research was conducted at the experimental farm of Faculty Agriculture, Riau Islamic University, Pekanbaru during 5 months, starting from October 2019 to February 2020. The study used a Factorial Completely Randomized Design by using two factors. first factor titonia compost (T), consisting 4 levels, namely 0, 0.5, 1.0, and 1.5 kg/plot second young coconut coir liquid waste (S), 100, 200, ...

An artificial neural network (ANN) model was developed to predict the removal efficiency of chromium (VI) from aqueous solution using a Borasus flabellifer coir powder as adsorbent. The effect of operational parameters such as pH, adsorbent dosage, and initial chromium (VI) concentration are studied to optimize the conditions for the maximum removal of chromium (VI) ions. The ANN model was deve...

Poly lactic acid or poly lactide (PLA) is a natural polymer that biodegradable, thermoplastic and an aliphatic polyester made from renewable materials such as young kepok banana starch. with the chemical formula CH3CH(OH)COOH biodegradable obtained combination of monomers. Therefore, in this study PLA matrix was added fillers form Coir Chitosan. coconut fiber has been widely used by researchers...
