The process of treating the Silane Coupling Agent solution on the composite surface is done manually layered on the composite surface. Composites tensile strength were tested referring to ASTM D 638-14, impact strenght tested referring ASTM D 256-04, and Water Absorption using ASTM D 570. Surface examination was made with a Scanning Electron Microscope (SEM). The Silane Coupling Agent (SCA) coating has succeeded in increasing the bond between kenaf fibers, empty oil palm bunches and epoxy be effective and in accordance with increasing tensile strength, impact strength and water absorption.

Abstract

This study aims to examine the effectiveness of the addition of Silane Coupling Agent on physical properties (density, moisture content, thickness expansion, and water absorption) and flexural strength in the manufacture of areca nut peel fiber particle board with urea formaldehyde adhesive. The betel nut peel fiber was alkalized using NaOH for 2 hours, then mashed using a grinding machine until it passed a 50 mesh sieve. The betel nut skin fibers that have passed the sieve are then treated with a solution of Silane Coupling Agent. The concentration variations of the Silane Coupling Agent solution were 0%, 2%, 4%, 6% and 8%. The betel nut peel fiber that has been synthesized with a silane coupling agent solution is then mixed with urea formaldehyde resin in a ratio of 30/70 in weight percent. The particleboard compaction process uses a Hydraulic Cold Press compacting machine with a pressure of 5 bar and a holding time of 120 minutes. The results of this study indicate that the silane coupling agent treatment increases the bond between the matrix and filler as shown in the SEM test on particle boards with 8% silane coupling agent treatment. The results of the particleboard test on density, percentage of moisture content, percentage of thickness development have met the standard of SNI 03-2105-2006. The results of the water absorption test have met the ASTM D 570 standard. The results of the flexural strength test on the SCA 6% variation SNI 03-2105-2006 decorative particle board type 8 and the SCA 8% variation have met the SNI standard 03-2105-2006 structural particle board type 10.5.

Abstract

Audit energi pada gedung atau bangunan sangatlah penting terutama penggunaan energi listrik, porsi pemakaian serta alokasi dana untuk penyediaan energi listrik merupakan salah satu yang dominan. Langkah untuk menghindari terjadinya pemborosan energi listrik, direktorat pengembangan energi telah membuat petunjuk konservasi energi pada bangunan gedung yang mengkonsumsi energi cukup besar. Pada penelitian ini telah di bangun sebuah sistem audit Intensitas Konsumsi Energi (IKE) listrik berbasis GUI yang sesuai dengan peraturan pemerintah pada SNI 6196 tahun 2011. Sistem audit Intensitas Konsumsi Energi (IKE) listrik dapat digunakan pada empat klasifikasi gedung yaitu komersial, rumahsakit, hotel, dan swalayan. Pengujian sistem audit menggunakan data Gedung Dakwah Pimpinan Wilayah Muhammadiyah(PWM) Provinsi Riau. Hasil pengujian sistem audit Intensitas Konsumsi Energi (IKE) listrik berbasis GUI Matlab yang dibangun dibandingkan dengan hasil perhitungan dengan Microsoft excel menunjukan bahwa perbedaan perhitungan kecil dari 0,0001.

Abstract

Gypsum is a composite material product that is used as a building material and is commonly used as building partitions, ceilings, bulkheads, and room accessories. However, gypsum also has a weakness in terms of ductility and is not waterproof. EVA (Ethylene Vinyl Acetate) is a polymer that transforms with an environmentally friendly waterproof mortar. The purpose of this study was to determine the process of making gypsum board with the addition of EVA to determine the effect of EVA polymer on gypsum board. The gypsum and EVA ratio variables used were GPC (100% : 0%) and GPEVA (88% : 12%). The procedure used in this experiment is sample testing, namely density test, water content test, water absorption test, and flexural strength test. Gypsum board composite by adding EVA to the density test, the density value of the GPC sample was 1.28 g/cm³, while the GPEVA sample (88%: 12%) was 1.27 g/cm. To test the water content and water absorption for the GPC sample, it was 5.5% and 62.5%, while for the GPEVA sample the values ​​were 4.7% and 14.5%, respectively. For the flexible strength test the control has a value of 1.3 N/mm² on the sample; GPEVA has a value of 0.95 N/mm². The addition of 12% EVA in the manufacture of gypsum board effectively increases the ability of gypsum to hold water by 76.75%..

Abstract

Water hyacinth is a waste in waters that can damage the balance of aquatic ecosystems because of its rapid growth, which can reach 3% in a day. One utilization of water hyacinth waste is to be used as filler material for decorative particleboard. This study aims to look at the physical and mechanical characteristics of particleboard with surface coating treatment using silane coupling agent solution.. Water hyacinth fiber was selected as an alternative filler material for the particle board composite due to its abundant availability and potential fiber properties. The surface of the particle boards was modified using a silane coupling agent (KH550) to enhance the bond quality between components. The water hyacinth powder was first alkalized with NaOH and distilled water (1:5) for 1 hour, then mixed with epoxy resin in a 40:60 weight ratio. The compaction process was carried out using a hydraulic hot press at 2 bar pressure and 50°C temperature for 10 minutes. The resulting particle boards were tested for density, moisture content, water absorption, and thickness swelling. Flexural testing was conducted in accordance with ASTM D790-03, and tensile strength testing followed ASTM D638-14. Surface morphology was observed using a scanning electron microscope (SEM). The results showed that the application of a silane coupling agent improved the bond between the matrix and filler, and the produced particle boards met the quality standards for density, moisture content, water absorption, thickness swelling, flexural strength, and tensile strength.
