“…VSM determines the current state of qualitative analysis in the manufacturing process. The current state depicts a map containing information about the current production process to facilitate the identification of the waste generated in the process (Kundgol et al, 2019;Lugert et al, 2018;Manjunath et al, 2014;Mertens et al, 2020;Mudgal et al, 2020b;Pathania et al, 2021). The results of this study indicate that the average production (AP) is 20,359.75 tons/month, and the average demand (AD) is 22,741.83 tons/month.…”

Applying Value Stream Mapping (VSM) in the mining industry can increase productivity in production process activities. The coal mining industry has a vital role in life and is an essential investment in the regional economy. However, since 2017, coal production has experienced instability based on data from the Central Bureau of Statistics for East Kalimantan Province (2021) and has yet to meet consumer demand. Previous studies have only shed light on the critical theory that VSM has extended to many industries. However, those studies need to explain the concept of applying VSM to the mining industry. Therefore, to support this theory,a case study from the mining industry was conducted to determine cycle times and identify value-adding and non-value-adding activities. A current state map is developed after making the necessary observations and calculations. Different improvement proposals are identified, and a future state map for the industry is constructed. As a result, a 23.4% reduction in cycle time and 56.1% reduction in lead time ensure its applicability in the mining industry to increase productivity and meet customer demands. VSM is a powerful tool that helps mining managers and operators identify waste and opportunities for improvement. Efficiency is one of the most important things to consider in this industry. This study is especially true in the coal mining sector.

An effort is made to find the solution to the new challenges of modification advancements in ferrite technologies. The hypothetical variation in the structural, magnetic, and electrical properties of cubic spinel magnesium aluminum ferrites introduced by the substitution of doping elements has been rationalized and proven. The outcome of aluminum substitution on the magnesium ferrites has been examined and investigated. Spinel ferrites having compositions of MgAlxFe2-xO4 (x = 0.1, 0.2, 0.3, 0.4) were prepared by the sol-gel auto-combustion method. The prepared sample’s characterization, such as scanning electron microscopy (SEM), DC electrical resistivity, AC electrical resistivity, and dielectric properties measurements, were tested using the respective instruments. The grain size and crystal size of all samples were measured from the micrographs of SEM and XRD Data. It is found that the average grain size is within the range of 300 nm - 550 nm for all different series that are formed, keeping the samples at 1100 °C sintering temperatures. A two-probe method experiment with a temperature range of 30 °C to 500 °C gives data on DC electrical resistivity. The Curie temperature depends on the sintering temperature, and it increases with increasing doping concentration. Also, doping influences grain size, which decreases with increasing concentration. Analyzing the SEM micrographs, it is found that the average grain size must decrease in tendency with increasing Al content. DC electrical resistivity exhibits excellent semiconducting behavior. Frequency dependence, dielectric constant, and dielectric loss factors were measured, keeping the frequency range of 75 Hz to 130 MHz at room temperature. The result shows that the dielectric constant (e) and dielectric loss tangent (tan™) decrease with the increase in frequency, while the AC resistivity and Q-factor increase. Comparing the electrical properties of four compositions, it can be suggested that the mixed ferrite, sample-4 (x = 0.3), shows the highest Q-factor of all at 1100 °C.
