Abstract

Termites are commonly seen as a nuisance due to their capacity to cause harm to wooden objects. The occurrence of termite infestations on furniture has led to a rise in financial damages attributed to such attacks. Hence, it is of utmost need to seek alternative raw materials that exhibit resistance to termite-induced deterioration, thereby fulfilling the requirement for substituting particle board. The present study has successfully demonstrated the fabrication of particle board by including bintaro fruit seed filler and urea formaldehyde matrix. The primary objective of this research endeavor was to explore an alternate approach to standard particle board production, specifically focusing on the development of anti-termite qualities. The filler fraction to matrix fraction comparison exhibits variations of 50:50, 60:40, 70:30, and 80:20. The particle board production process employed in this study utilizes a cold pressing method, wherein a pressure of 15 MPa is applied for a duration of 120 minutes. The board particles that have been acquired are subjected to testing in order to ascertain their physical characteristics, such as density and water content. The experiment was conducted in compliance with the SNI Standard 03-2105-2006. The flexural strength of particle board was evaluated in accordance with the standard SNI 03-2105-2006. An assessment was conducted to evaluate the susceptibility of particle board to termite infestation, in accordance with the guidelines outlined in the SNI 01-7207-2006 standards. The density and moisture content testing findings conducted on particle board match with the specifications outlined in the SNI 03-2105-2006 standard. The experimental outcomes evaluating the susceptibility of board particles to termite infestations have effectively fulfilled the requirements outlined in the SNI 01-7207-2006 standards.

Abstract

Utilizing palm frond biomass for the production of composite materials will have a positive impact on managing palm oil plantation waste. Palm frond fiber biocomposite products have been proven to have good mechanical properties. However, exploration of other physical properties, especially thermal insulation properties, has not been widely studied. As a non-conducting material, palm frond fiber has the potential to have good thermal insulation properties. This study aims to fabricate palm frond biocomposite fiberboard, which has potential as a thermal biocomposite material. Fiberboard is made using the manual hand lay-up technique and cold compaction using a press machine. The characteristics under consideration for the fiberboard in concern encompass its physical, mechanical, and thermal properties. The main ingredients utilized in the fabrication of fiberboard predominantly comprise palm frond fiber and epoxy resin, with five distinct sample variants denoted as PSP-1 (84% fiber:16% resin), PSP-2 (83% fiber:17% resin), PSP-3 (82% fiber:18% resin), PSP-4 (81% fiber:19% resin), and PSP-5 (80% fiber:20% resin). The experimental results obtained from the testing of physical parameters indicated that the density of fiberboard exhibited a range of values spanning from 0.28 g/cm3 to 0.55 g/cm3. Similarly, the fiberboard's water absorption capacity varied between 107.25% and 194.00%. The water absorption abilities display significant variability, as indicated by a large standard deviation ranging from 28.15% to 80.35%. When the density of fiberboard is high, its water absorption capacity tends to be low. Furthermore, the mechanical tests revealed that the fiberboard's flexural strength showed a range of values spanning 1.10-5.42 MPa. The magnitude of specific heat capacity for fiberboard is calculated to be between 2.1-3.5 J/g ̊C, while the thermal conductivity lies within the range of 0.001-0.0020 W/mK

Abstract

Palm kernel shell (PKS)-based carbon aerogel holds potential as a cathode material in lithium-ion batteries due to its porous structure and high conductivity. This study aims to determine the optimal calcination temperature to enhance the physical and thermal properties of PKS-based carbon aerogel. Calcination was performed at 400°C for 3 hours and 450°C for 2 hours to analyze the effects on morphology, thermal stability, and density of the carbon aerogel. Scanning Electron Microscope (SEM) analysis revealed that calcination at 450°C produced a more porous and irregular structure, which supports optimal ion movement. Differential Scanning Calorimetry (DSC) testing showed higher thermal stability at 450°C, with a total energy of -74.54 J/g. Additionally, the density of carbon aerogel at 450°C was 0.75 g/cm³, lower than 0.83 g/cm³ at 400°C, indicating better porosity for ionic conductivity. Therefore, a calcination temperature of 450°C for 2 hours is recommended as the optimal condition to improve carbon aerogel performance for lithium-ion battery cathode applications.

Abstract

Temperature checks and wearing masks are an effort to reduce the transmission of Covid-19. Manual checking is impractical and spent time screening many people in public areas. This work propose a portable smart door that simultaneously detects the body temperature and mask of the people. Temperature detection uses MLX90614 sensor and Arduino, while mask recognition uses digital camera with artificial neural network (ANN). Component test and completion test are conducted to examine the smart door performance involving 20 volunteers. The door was tested to measure the body temperature of the volunteers with and without a mask. The measured temperature was compared with measurements of a thermal gun. The door will open automatically if the temperature is below 37.2°C and wearing a mask, while remaining closed if above 37.2°C or not wearing a mask. The temperature sensor works properly with a small deviation and saving time almost half of thermalgun response time. The accuracy of mask detection by the ANN is also at a high level of confidence. These findings demonstrate the applicability of the smart door for screening body temperature and mask in public areas for faster and precise.

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.

Abstract

The majority of air conditioning systems, including both cooling and heating systems, consume a significant amount of electrical energy as a result of their high electrical consumption and prolonged periods of operation. The use of thermal insulation materials in the building can help conserve electrical energy used for room conditioning systems. Natural fibers are used as an alternative in the production of thermal insulation, which is commonly referred to as bio-insulators. The utilization of oil palm trunk (OPT) fiber as the primary material for thermal insulation shows promise. This study aims to determine the specific attributes of OPT fiberboard that make it suitable for use as a thermal bio-insulator. The features examined encompass physical, mechanical, thermal, and fire-resistant attributes. The OPT fiber underwent a treatment process involving boiling at a temperature of 80℃ for a duration of 30 minutes. The fiberboard is manufactured using epoxy adhesive and calcium carbonate additive, and then printed using the hand lay-up process and cold-compaction technique. The physical characteristics of fiberboard indicate that there is a direct relationship between its density and water absorption.  Testing revealed that fiberboard has a low thermal conductivity and high heat capacity value. By including calcium carbonate, the burning time of the fiberboard was tested and seen to decrease, indicating a delay in the fiberboard burning process, as evidenced by the extended flame suppression time. The density of OPT fiberboard varies between 0.48 and 0.70 gr/cm3. The absorbency of water is inversely related to its density. Water absorption capacity generally rises with decreased density. The obtained heat capacity value is 1.28-2.38 J⁄(g℃). The mechanical value ranges from 1.00 to 3.55 MPa. The incorporation of calcium carbonate significantly impacts the thermal and mechanical characteristics of the fiberboard. The produced OPT fiberboard satisfies the requirements for good thermal, physical, and mechanical characteristics, making it a suitable bio-insulation material for buildings.

Abstract

Separator dalam baterai litium-ion memegang peran krusial dalam mencegah kontak langsung antara elektroda positif dan negatif, yang dapat menyebabkan bahaya kebakaran. Penelitian ini dilakukan dengan mengusulkan penggunaan limbah tandan kosong kelapa sawit (TKKS), sumber alami yang kaya selulosa, untuk menghasilkan selulosa asetat yang diaplikasikan sebagai bahan dasar dalam pembuatan membran polimer elektrolit. Membran ini diintegrasikan ke dalam baterai sebagai pemisah yang berfungsi ganda, tidak hanya sebagai penghalang fisik tetapi juga sebagai media transportasi antara anoda dan katoda. Penelitian ini merupakan eksperimen dengan desain satu faktor yang variabelnya melibatkan kombinasi polivinilidena fluorida (PVDF), selulosa asetat (CA), dan titanium dioksida (TiO2) dengan komposisi berbeda: PVDF (2.8%:0%), PVDF:CA (2.8%: 12%), dan tiga variasi PVDF:CA:TiO2 (dengan konsentrasi TiO2 0.75%, 0.65%, dan 0.55%). Metode pengumpulan data meliputi uji fisik (porositas, ketebalan, dan voltametri siklik), uji mekanis (kekuatan tarik dan biodegradabilitas), serta pengamatan morfologi menggunakan Scanning Electron Microscopy (SEM, Hitachi TEM 3000 Series). Analisis menunjukkan bahwa membran dengan komposisi PVDF:CA:TiO2 (2.8%:12%:0.75%) memiliki sifat mekanis optimal, kekuatan tarik terbaik 61.8854 MPa dan porositas tertinggi 57%. Penambahan TiO2 dan selulosa asetat tidak hanya meningkatkan kekuatan mekanis dan porositas tetapi juga mempercepat proses biodegradabilitas dengan penurunan berat hingga 68% menjadikannya efektif sebagai separator dalam baterai litium-ion.
