Abstract

Ducting is a supporting component of the HVAC system. (Heating, Ventilation, and Air Conditioning). In other words, ducting can be used as an air supply, and as a channel for both cold and hot air, air drainage, air absorption, and ventilation. It is used to ensure that the air quality in the room is awakened according to the needs of the room. In the selection of material for ducting, one can consider various aspects. In this journal, the aspects considered are the corrosion rate, ultimate tensile strength, and the material price of the three types of materials, namely BJLS, aluminium, and stainless steel. Based on the results of the test and calculation, BJSL has the highest corrosion rate of about 0.62 Mpy on the 14th day, stainless steel has a corrosive rate of around 0.29 Mpy on the 14th day, and aluminum has the lowest rate of corrosiveness of about 0,27 Mpy at the 15th day.

Abstract

The effectiveness possessed by manufacturing machines is a parameter used to determine the performance of a company's manufacturing process. Effectiveness can be shown in the form of percentages as effective as a manufacturing process is carried out. Effectiveness can be a reference for companies in the implementation of production by evaluating charts of production that are considered less effective and do not meet standards. The factors that affect the effectiveness of a production machine can be seen in the availability or capability, quality, and performance where in this article the overall equipment effectiveness (OEE) method which has a production period of one month is used to get the effectiveness of the production process carried out. The results obtained in this study were 88.53% in the first week of proposition, 94.63% in the second week of production, and 91.58% in the third and last week of production.

Abstract

Agriculture waste-based materials have considerable potential as wood-based particleboard alternatives. It has been produced abundantly from nature and considers an eco-friendly material. One of the enormous resources is the paddy by-product, rice straw (about 500 million tonnes per year worldwide). In this work, the mechanical properties of rice straw-based particleboard are predicted easily and quickly using the sessile drop method.  Rice straw was crushed into 2-5 mm diameter powder-like materials, and corn starch was used as the binder. The rice straw particleboard was formed under a hot press machine (5 MPa, 180°C and 120 minutes). Conventionally, the sample mechanical property was tested through Universal Testing Machine (UTM). Unfortunately, the process is costly and difficult to access. It is necessary to have a rapid and low-cost presumption of the mechanical particleboard properties toward more efficient manufacturing. This work proposes a simple sessile drop method to indicate particleboard mechanical properties. Multiple linear regression was performed to see the correlation between sessile drop and UTM testing. It was found statistically that the sessile drop method could be used as an early prediction of particleboard mechanical properties.

Abstract

The rise in carbon dioxide (CO₂) emissions has accelerated efforts to develop environmentally sustainable alternative carbon capture and utilization technologies. Among the promising approaches is the use of ammonium hydroxide (NH₄OH) for CO₂ capture. The objective of this study is to systematically investigate the influence of CO₂ flow rate, temperature, pH, NH₄OH concentration, and stirring speed on the performance of CO₂ capture, as determined through a comprehensive literature review. The review findings demonstrate that each of these variables plays a critical role in enhancing CO₂ capture efficiency, as evidenced by the increased percentage of CO₂ removed. Temperature and pH directly influence the chemical equilibrium of the reaction, whereas stirring improves the diffusion of gas into the liquid medium. The interrelated effects of these parameters highlight the necessity of adopting a systematic approach to process optimization. In conclusion, an in-depth understanding of these influencing factors is essential for the development of a robust and sustainable CO₂ capture system. It is recommended that future studies incorporate integrated experimental research, process modeling, environmental impact evaluations, and product analyses to support the scaling up of this technology for mini-plant and commercial-scale implementation.
