Abstract

Machines in manufacturing areas often cause noise. The noise comes from machine tools such as lathes, milling machines, grinder machines, and other tools that cause sound and vibration so they are prone to causing physical and psychological disorders. This study was to determine and analyze the noise level in three areas and ten points in the manufacturing room of The Job Training and Development Center Serang by the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia Number PER.13/MEN/X/2011 with the maximum noise limit that has been set is 85 dBA. As for the results of the ten points, there is a point that exceeds the threshold value, namely at point 6 (85.8) dBA in the lathe area. Every operator in the manufacturing room that has a noise level that exceeds the threshold value must wear personal protective equipment in the form of earplugs or ear muffs that have been provided by the workshop to reduce the noise level.

Abstract

Roof tiles play a vital role in the construction industry hagoslot by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

The utilization of biomass waste as a reinforcing agent for biocomposites presents an attractive alternative in the development of environmentally friendly materials. This study aims to analyze the effect of varying percentages of chicken eggshell and crumb rubber fillers, as well as the hot press temperature, on the mechanical properties of the biocomposite, including the Modulus of Rupture (MOR), Modulus of Elasticity (MOE), and strain. The Taguchi method with an L9 orthogonal array design was employed to evaluate the effect of each factor and determine the optimum process combination. The research findings indicate that a 10% filler concentration yielded the highest stiffness, while a 20% filler concentration resulted in the largest strain value and demonstrated the best balance between strength and flexibility. A temperature of 170°C emerged as the most stable condition for most mechanical parameters, whereas a temperature of 190°C provided an increase in strength at higher filler compositions. From this study, it was ascertained that the optimal parameters are a 20% filler concentration and a temperature of 170°C (N1), yielding MOR, MOE, and strain values of 1473.53 MPa, 1186 MPa, and 2.86%, respectively. These findings affirm the critical importance of controlling the filler composition and processing parameters in producing biocomposites that are consistent and high-performing.

Abstract

Adhesive technology has seen significant advancements in recent years. Compared to welding or threaded joints, adhesives provide a straightforward mechanism for joining material interfaces. Due to practicality allows for the potential development of adhesives with strengths comparable to those of traditional joints. In this study, a modified type of Polyvinyl Acetate (PVAc) adhesive was utilized as a binder for mahogany wood surfaces. The choice of PVAc adhesive is due to its common use in everyday applications, particularly in the woodworking industry. Additionally, this adhesive is relatively safe for both health and the environment. The study examined three types of adhesives: PVAc white adhesive, PVAc yellow adhesive, and a combination of the PVAc white and yellow adhesive. These adhesives were used to bond the wood surfaces, and the bond strength at the interface was evaluated through a flexural test. The results showed that the adhesive strength of white adhesive reached 111 MPa, while the mixed adhesive and yellow adhesive exhibited flexural strengths of 74.2 MPa and 63.4 MPa, respectively. Notably, the presence of white glue was found to enhance the flexural strength of mahogany wood even in the absence of adhesive.

Abstract

Deflector Roll plays an essential role in the manufacturing of tinplate at PT Pelat Timah Nusantara (Latinusa), Tbk. This research examines the corrective maintenance procedure by employing the breakdown method to pinpoint repeated problems and their resolutions. The primary issues noted include degraded bearings, soiled surfaces, and uneven rollers, all of which hinder production continuity. The maintenance procedures consist of disassembling, examining, replacing, cleaning, balancing, and reassembling. Analyzing 55 documented damage occurrences from 2015 to 2024 reveals that surface-related problems were predominant, with 9 instances (16.36%) of glossy smooth surfaces, followed closely by surface buckling (14.55%) and dirty surfaces (14.55%). The outcome indicates that organized maintenance enhances efficiency and extends roll lifespan
