The global demand for wood as a building material is steadily growing, while the availability of this natural resource is diminishing. This situation has led to the development of alternative materials. Of the various synthetic materials that have been explored and advocated, polymer composites claim a major participation as building materials. There has been a growing interest in utilizing nat...

Dimension reduction for regression (DRR) deals with the problem of finding for high-dimensional data such low-dimensional representations, which preserve the ability to predict a target variable. We propose doing DRR using a neural network with a low-dimensional "bottleneck" layer. While the network is trained for regression, the bottleneck learns a low-dimensional representation for the data. ...

The community assistance program in utilizing oil palm coir Kolaka Regency, Southeast Sulawesi for supporting materials from the GRC mixture is a new breakthrough use of waste. This activity expected to overcome problem waste and make it economic source surrounding community. purpose this increase public knowledge so that can be value understanding process making by method used utilization fibe...

Activated carbon (AC) has been prepared from raw coconut pith and coconut pith impregnated with H3PO4 and NaOH solutions separately. AC was characterized with SEM, particle size analyzer and proximate analyzer. Adsorption studies were carried out using UV and atomic absorption spectrophotometer to find its effectiveness. AC obtained from coconut pith treated with phosphoric acid was found compa...

Coconut husk is a waste from coconut plantation production and tofu solid production. One problem the tannin content that can inhibit plant growth low nutrient of coir. This study aims to determine effectiveness mixture as planting medium for germinating green beans, bok choy, red chili in supporting organic farming. research was carried out Kaliabang Tengah District, North Bekasi District. Fro...

The objective of work was focused to investigate microstructure of polyurethane foam and cyclic crushing strength of its sandwich structure which made of sisal / coir / bamboo / glass fabrics as reinforcement with polyester resin to form composites skin. The tested sandwich panels were constructed four type of FRP faceplates made of sisal / coir / bamboo / glass fiber reinforcements impregnated...

Rose plants (Rosa x hybrida L. CV. Kardinal, grafted on Natal Brier) were grown in UC mix and in coconut coir. Water release curves and hydraulic conductivity of the media were measured. Water tensions in the media were maintained within a predetermined narrow range by tension-actuated irrigation, using high-flow electronic tensiometers. Transpiration rate of plants sitting on load cells was me...

Cellulose nanofibers were isolated from coconut coir fibers by chemical treatment using alkaline, mineral acids and inorganic salts, followed by mechanical treatment and disintegration methods like sonication, cryo crushing and dissolution. The size and morphology of cellulose nanofibers were investigated by using the Field Emission Scanning Electron Microscope (FESEM). The width of synthesized...
