Abstract

Bahan penyerap memiliki karakteristik akustik yang memantulkan dan menyerap gelombang bunyi. Penyerapan oleh bahan berpori sangat berguna untuk mengurangi tingkat kekuatan bunyi yang terjadi sehingga dapat mengurangi kebisingan di dalam ruangan. Koefisien Penyerapan Bunyi (NAC) dari Acoustic Sandwich Composite (ASC) diuji dengan menggunakan tabung Kundts Tube impedansi dua mikrofon sesuai dengan standar ASTM 1050-98. Dimensi ASC terdiri dari 1 inti dan 2 kulit dengan diameter 100 mm. Kulit di sisi bagian depan didisain memiliki 5 lubang (d = 10 mm) dengan variasi 4 ketebalan yang berbeda dari busa poliuretan (busa-PU) yaitu 10, 20, 30 dan 40 mm yang digunakan sebagai inti dari ASC. Kulit atau skin di kedua sisi komposit sandwich terbuat dari poliester yang diperkuat bahan serat alam agave sisalana acak dan panjang dengan tebal 5 mm. Nilai Koefisien Penyerapan Bunyi (NAC) diberikan nilai 0-1, yang berarti penyerapan bunyi tidak ada akan bernilai 0, dan penyerapan bunyi mencapai maksimum apabila bernilai 1 pada rentang frekuensi 0 Hz -1,6 kHz. Pada penelitian ini terlihat sifat busa polyurethane dengan ketebalan 30 mm baik pada rentang frekuensi rendah dengan nilai NAC tertinggi adalah 0,46. ASC dengan ketebalan busa PU 30 mm memiliki kenaikan harga NAC di frekuensi rendah (400 Hz-1000 Hz), nilai tertinggi 0,80 di frekuensi 800 Hz. ASC dengan ketebalan busa PU 10 mm baik untuk frekuensi menengah (1000 Hz-1600), nilai tertinggi 0,89 pada frekuensi 1200 Hz.

Abstract

The advancement of information technology provides ease of learning. However, learning media in schools usually depends on average electrical settings and electronic devices to support information technology (IT). The learning media in Indonesia generally depends on the utilization of PLN's electrical energy. It is undeniable that electricity is a basic need in teaching and learning activities today, even though the existence of electrical installations in the midst of children saves dangers that need to be anticipated. The solution is to provide socialization and education on child-friendly technology. In this case, the school community will be introduced to utilizing and building safe electrical installations for children. In principle, some electrical components available on the market will have their own level of safety, and safe and child-friendly components must be chosen. Furthermore, electrical installations will be built with solar energy sources because the technology has many advantages, including renewable energy, without high-voltage cable networks, and providing efficiency in school operational costs. It is more important that solar electricity can work at low voltages to be safe in children's environments. The result at the activity location installed electricity from Solar Power Plant with a 300 Watt inverter to provide electricity for school computer devices. In addition, 10 outdoor lighting points are installed that are set to turn on and off automatically. The main goal to provide efficient and safe electrical facilities for children has been well realized.

Abstract

Hybrid layered composites (HLC), combining natural and synthetic fibers, are mainly used in the automotive composite industry. The factor determining the inter-mechanical bond between layers impacts the mechanical strength.. Ramie fibers were immersed in a 5 wt.% NaOH solution for 2 hours to remove lignin and hemicellulose content in the fiber surface. Alkali treatment increases the adhesion bond between cellulose and the polyester matrix. The treated ramie fibers to be weaved by traditional machine to produce the woven ramie. The three-layer fibers are manufactured by press mold with a 2-bar pressure. The characterization of HLC for tensile strength according to ASTM D638 and water absorption refers to ASTM D570. The excellent tensile strength and elastic modulus of HLC have a stacking sequence of woven ramie-unidirectional glass-woven ramie (WR-UG-WR) by 150 MPa and 24.1 GPa, respectively, and its lowest water absorption by 3.31%.

Abstract

Natural fibers are progressively employed in manufacturing polymer composite structures beneficial to automotive, construction, and aerospace industries. The upsurge in the utilization of natural fibers in various industries is ascribed to enhanced awareness of the toxicity of man-made fibers. It is imperative to preserve the ecosystem. Thus, legislators and investigators are brainstorming on substituting conventional materials with earth-friendly resources. Natural fibers are green resources with multifarious advantages over synthetic materials, including ease of processing, reduction of CO2 effusions, biodegradable, recyclable, acceptable thermomechanical attributes and improved compatibility with human health. Therefore, natural fibers are widely applied as modifiers for polymers. Recently, natural fibers reinforced polymeric composites, bio-composites and bionanocomposites are the hot potato of researchers ascribed to their attributes such as having low specific gravity, producing good results without costing a lot of money, earth-friendly, and sustainable among others. Jute, kenaf, coir, and hemp natural fibers derived from plants can be exploited to achieve novel lofty execution polymer composite systems. Thermo-mechanical behavior of natural fiber-reinforced composites, bio-composites and bionanocomposites including stress-strain, bending, failure resistance, impact toughness, temperature and deformation fashion them to be more sustainable and engaging than man-made fibers with exceptional biodegradable hallmark. Thermomechanical analysis (TMA) determines variations in specimen dimensions with varying temperature, time or load at ambient conditions. However, TMA of natural fiber-reinforced polymer composites is limited. Therefore, the review highlights on natural fiber-reinforced polymer composites, bio-composites, bionanocomposites, their crucial thermo-mechanical attributes, and emerging implementations.

Abstract

The potential of natural resources in tropical countries is very diverse. one of them is the abundant agricultural products. but there are some obstacles in the post-harvest cycle and the continuous availability when the harvest season ends. various methods of preserving agricultural products have been tested from conventional methods to advanced technology. one of the technologies for preserving agricultural products is freeze drying. various innovations continue to be tested until they get consistent results with good energy efficiency. This method was originally started in the pharmaceutical industry. Various treatments and flexible adaptations make this method penetrate the food industry to maintain the quality of food products. In the food industry, freeze drying is suitable for food products such as meat, fruits, grains, and vegetables. The advantage of freeze drying is that the food products produced do not change shape, form, texture, taste, and nutrition even though they have gone through the drying process. Of the various characteristics of fruits and vegetables have their own properties that can be changed with the temperature parameters applied in the freeze dryer method.

Abstract

This study investigates Wood Plastic Composites (WPCs) by incorporating waste Expanded Polystyrene (EPS) and various wood powder reinforcements. The mechanical properties of WPCs play a pivotal role in sustainable material development. Our research delves into the effects of different treatments on wood powders and their interactions with the polymer matrix.Pine, teak, and silk tree wood powders underwent alkali immersion and coupling agent treatments. The ensuing composites underwent rigorous testing, including flexural strength, hardness, and impact resistance assessments.The findings underline the complex factors governing WPC mechanical properties. Pine-based WPCs, reinforced with pine wood powder and subjected to alkali treatment, exhibited the highest flexural strength at 29.56 MPa, whereas the lowest flexural strength of 14.65 MPa was observed in WPCs reinforced with alkali-treated teak wood powder. The highest impact strength quantified at 2.54 kJ/cm², was found in untreated pine wood powder-based WPC. In contrast, the lowest impact strength was identified in teak wood powder-based WPC treated with alkali.
