Abstract

The development of Industry 4.0 has pushed manufacturing firms to accelerate information flow, improve decision accuracy, and reorganize communication on the shop floor. This study aims to analyze practitioners’ perspectives on the need for digital transition through the use of management visualization boards. A qualitative case study design was applied through 12 semi-structured interviews, 9 observations of production briefings, and a review of 18 supporting documents. The findings show that management visualization boards still function as the main medium of daily operational communication because they help teams review targets, discuss problems, and determine corrective actions quickly. Manual boards were considered superior for briefing flexibility, especially for marking issues, drawing arrows, and making short sketches during discussion. However, manual data updates were time-consuming, created duplicate recording, and made problem histories difficult to trace. Digital boards were seen as neater, easier to monitor, and more supportive for reading trends, but they could not fully replace manual boards because they did not yet support spontaneous discussion and not all data were automatically integrated. Practitioners mainly expected faster data updates, lower administrative burden, stored action histories, and cross-shift and cross-unit information access. These results indicate that digital transition should proceed carefully in production environments overall.

Abstract

The analysis of mineral oxide content in sand plays an important role in determining the quality of raw materials for the chemical and construction materials industries, yet the application of conventional methods based on national standards remains relatively limited compared with the use of modern instruments. This study aimed to analyze the content of silicon dioxide (SiO₂), calcium oxide (CaO), and magnesium oxide (MgO) in sand using a gravimetric method in accordance with the SNI 2049:2015 procedure. A quantitative approach with a laboratory experimental design was employed, in which sand samples were analyzed through successive stages of dissolution, precipitate separation, ignition, titration, and weighing of the pure compound residues. Data were obtained from gravimetric and volumetric measurements and were analyzed quantitatively based on the stoichiometric relationships of the chemical reactions. The results showed that the SiO₂ content reached 84.0%, while CaO and MgO were 1.16% and 1.13%, respectively, indicating the dominance of silica in the sand composition with relatively low levels of basic oxides. These findings confirm that the gravimetric method based on the national standard is capable of producing accurate and consistent data for sand mineral characterization, thereby reinforcing the potential use of sand as a raw material for high-silica-based industries.

Abstract

Coal quality testing is important to determine fuel characteristics before use for industrial purposes. This study aims to analyze the values of Moisture in Analysis, Volatile Matter, and total sulfur content in coal samples through laboratory practice at PT SUCOFINDO Padang Branch. This study used a quantitative descriptive approach with a laboratory practice method. Data were collected through duplicate testing of coal samples using an oven, VM furnace, sulfur furnace, analytical balance, desiccator, aluminum crucible, Volatile Matter crucible, and sulfur crucible. The results showed that the Moisture in Analysis values in the coal samples were 27% and 22%, with an average of 24.5%. The Volatile Matter values obtained were 81% and 66%, with an average of 73.5%. Meanwhile, the results of total sulfur content analysis showed the same value in the two replications, namely 1.67%. These findings indicate that the coal samples had relatively high moisture and volatile matter contents, as well as sulfur content that needs attention because it may affect combustion efficiency, industrial equipment, and the environment. The conclusion of this study confirms that proximate analysis and sulfur content testing play an important role as a basis for assessing coal quality in industrial laboratories. The practical contribution of this study lies in strengthening understanding of coal quality testing procedures that are relevant to supporting the evaluation of industrial fuel quality.

Abstract

One of the objectives of the Biology Education study program is that students have entrepreneurial insights and competencies in the field of biology education that can contribute to self-development and society. Based on the objectives of this study program, it can be concluded that graduates of the study program are not only expected to become teachers but also to become entrepreneurs. Therefore, in the lecture process, it is hoped that each course can be oriented to foster students' entrepreneurial interest and motivation. This study aims to reveal how the entrepreneurial interest of Biology Education students after taking the Plant Structure and Development course. Because of the potential of this course if the right project assignment is developed in fostering the entrepreneurial spirit, this will be able to form graduates who have entrepreneurial competencies. This research is an exploratory descriptive research. The data were analyzed with descriptive statistics and the results of the data analysis were later interpreted in qualitative form. The results showed that 91.37% of students are interested in entrepreneurship and the level of entrepreneurial interest of students has a high category. Based on the results of the study it can be concluded that the entrepreneurial interest of Biology Education students after taking the course of Plant Structure and Development has a high category.
