Abstract

This study concentrates on the design and construction of a laboratory-scale centrifuge for the separation of gum from crude palm oil (CPO). The extraction of gum from CPO is essential in the palm oil sector to guarantee that the finished product adheres to quality standards and is safe for consumption. We engineered the prototype centrifuge to accommodate six 600-mL bottles and achieve a maximum rotational speed of 1400 rpm. The design procedure utilised Autodesk Inventor software for CAD modelling and computations to ascertain the centrifugal force, power capacity, and shaft diameter. The process of manufacturing entailed cutting and shaping stainless steel into the necessary components, subsequently followed by drilling and milling operations for mounting points and interfaces. We implemented surface treatment to augment corrosion resistance and elevate visual appeal. The assembling procedure encompassed component integration, motor incorporation, and control system configuration. The experimental configuration involved centrifugal testing utilising 600-mL glass bottles with time intervals of 10, 20, 30, and 40 minutes at an average rotational speed of 924 rpm. The experiment showed that the centrifuge worked well to separate the gum and other contaminants from the CPO. The best separation happened after 40 minutes of centrifugation.

Abstract

The goal of the article is to improve the thermal properties and energy efficiency of the walls and facades of the buildings by introducing the phase change material in the bricks. This study focuses on the thermal insulation capabilities of a paraffin-ice bag PCM mixture, aiming to enhance the thermal inertness of the bricks. The paraffin wax exhibits a high latent heat and is chemically stable, while the ice bags, with their low temperatures, serve as effective thermal regulators. They complement each other to address challenges such as the low thermal conductivity of paraffin and the leakage of low phase change transition temperature in paraffin. We made use of two types of paraffin and ice bag PCMs in a 50:50 ratio and embedded them in standard bricks. During the experiment, we coated the brick surfaces with liquid cement to enhance the hydraulic resistance of the PCM. Next, we inserted wires known as packing plugs into the bricks and filled the holes with powders. We also subjected the bricks to heating and cooling in cycles, ensuring the temperatures remained within a specified range. During the experiment, temperature sensors were utilized to capture data concerning thermal performance. The authors reached the conclusion that PCM polymer composite bricks possess a lot of promise such walls are being able to maintain their thermal performance parameters. When PCM-enhanced bricks are utilized, temperature changes were significantly restricted, staying constant during the times of peak heating and cooling. The PCM bricks also displayed efficient absorption and gradual release of energy due to the high energy transfer rates during phase change. This study suggests that PCM polymer composite bricks are cost-effective for the energy performance of buildings.

Abstract

The purpose of this study is to perform the tensile tests on chicken feather fiber composites to evaluate their potential in practical engineering applications. The study employed the experimental method as a laboratory activity, in which chicken feathers fibers were fused with epoxy resin at different ratios of 5%, 10%, 12% and 14% to form composite specimens. In order to find the ultimate tensile strength, yield strength and the modulus of elasticity of the composites, tensile testing of the composites was done according to the the American Society of Testing and Materials (ASTM) D3039 standard test method. Results showed that in as low as 5% cement reinforcement of chicken feathers, the mechanical properties of the resin were greatly improved, with the ultimate tensile strength reaching 48.672 N/mm² and the yield strength being 39.168 N/mm². This shows the promise of using chicken feather fiber composites as strong and light materials that are also eco-friendly for various uses. The discussion topics mentioned the behavior of stress-strain transition from elastic to plastic region on increasing the load, which showed the strength and flexibility of the composites are in essence, the opposite of each other. This study advances the view that there is more development to be done on chicken feather fiber composites to enable them satisfy the standards of various sectors thereby offering an environmentally friendly method in cutting waste and reducing the burden of the environment from synthetic materials.

Abstract

This research examines the effect of bricks enhancement with phase change material (PCM) consisting of paraffin on their thermal considerations. The experimental methods were aimed at investigating the mechanisms of temperature transfer throughout the thermal rounds, mimicking diurnal fluctuations of temperature. Due to the high amount of latent heat contained in paraffin a portion of it was transferred into regular bricks with temperature probes tracing the heat processes. It is shown that enhancement of bricks with PCM reduced temperature range and controlled the rate of heat transmission more than the ordinary bricks did. It was significant that the PCM-embedded bricks did not drift in heat and were able to stock up excess heat during the day and release it at night which resulted in monumental energy efficiency and comfort in thermal standing. The conversation additionally seeks to bring out the function of paraffin in insulation which does not only save energy consumption but goes forward to maintain comfortable temperatures within the building. The study finally achieved its goal and assert that energy saving with the use of PCM enhanced bricks in construction makes it a preferable material in regards to energy and the fight against climate change.

Abstract

This study explores the innovative use of chitosan from shellfish and natural cellulose as an additive to decrease the viscosity of used lubricating oils. We synthesized and applied chitosan and cellulose as adsorbents to filter impurities and enhance the rheological properties of the oil. During the experiment, different amounts of chitosan and cellulose were used, and the Ostwald method was used to measure the viscosity. As expected, adding more chitosan (20 grams) made the viscosity much better compared to mixes with cellulose. This led to a viscosity of 658.20 cP, while a 15:5 chitosan-to-cellulose ratio made the viscosity the lowest, at 513.06 cP. FTIR analyses confirmed the structural integrity of chitosan post-synthesis. Challenges in optimizing chitosan production, particularly in achieving standard deacetylation levels, were noted as potential limitations. The results suggest that using biopolymers like chitosan and cellulose together is a long-term way to improve oil recovery and reuse, lower waste, and make industrial uses better. In the future, researchers should concentrate on enhancing the manufacturing process of chitosan to enhance its adsorption capabilities, and explore alternative functional modifications that could enhance its utility in a wider range of scenarios

Abstract

This experiment investigates the heat transfer characteristics of an ice bag gel phase change material (PCM) incorporated within bricks. The study seeks to investigate the performance of ice bag gel as PCM in improving thermal behavior of building material. The experiment consisted of subjecting brick samples with and without ice bag gel PCM to thermal cycles in a semi-automated laboratory setup. The results indicate that ice bag gel PCM incorporated in bricks exhibited minimal changes and better heat transfer as compared to the dry bricks. It was observed that the ice bag gel PCM registered lower peak temperature and slower rates of temperature drop which means their heat storage and release characteristics were efficient. Furthermore, the ice bag gel system produced a steady radiation flux, indicating that it was able to minimize the effects of temperature variations. These results imply that ice bag gel PCM has the potential to be a green and economical option for enhancing thermal comfort and decrease energy consumption in buildings.

Abstract

The production process of wooden batik at Sanggar Peni Krebet plays an important role in preserving local culture and supporting the economy, but workers face the risk of musculoskeletal disorders due to unergonomic working positions when performing activities such as sculpting, sanding, batik making, and boiling . Based on the NBM questionnaire on 15 workers, the highest complaints were found in the right upper arm (100%), right wrist (100%), and waist (88%). Research using the RULA and REBA methods revealed the batik activity to have a very high risk (RULA 7, REBA 11), requiring immediate improvement, while boiling had a medium to high risk (RULA 5, REBA 9), requiring investigation and change. The EFD emphasizes the importance of designing batik boiling stoves, chairs and tables that consider height according to the worker's body size, ergonomic working positions, and comfortable strainer handles. Tool development should focus on improving comfort, safety and efficiency, with design adjustments to support workers' postures and use lightweight yet strong materials. The application of these elements is expected to improve safety and productivity in the batik industry.
