Abstract

This study aims to evaluate the lightfastness of organic ink formulated from purple sweet potato (Ipomoea batatas L.) pigment for screen-printing applications on 24s cotton combed fabric. The ink formulations varied the pigment amount (10, 15, and 20 grams) and solvent volume (distilled water) of 25 and 30 mL, while the binder and thickener components were kept constant. Lightfastness was assessed by measuring the change in lightness (ΔL*) before and after 24 hours of light exposure. The results showed that the formulation containing 15 g of pigment and 25 mL of solvent (P2A1) exhibited the best colorfastness, with an average ΔL* of 0.23, while the formulation with 10 g pigment and 25 mL solvent (P1A1) showed the poorest performance (average ΔL* of 1.86). A lower solvent volume resulted in higher resistance to light exposure. Moreover, using either too little or too much pigment negatively affected ink transfer and reduced lightfastness. Two-way ANOVA on log-transformed data revealed that the interaction between pigment concentration and solvent volume had a significant effect on ΔL* (p < 0.001), contributing 72.8% to the total data variation. This study confirms that achieving an optimal balance between pigment amount and solvent volume is crucial for producing organic ink with good lightfastness

Abstract

This study evaluates the implementation of Behavior Based Safety (BBS) in improving occupational safety compliance at PT Wichindo Pratama, a heavy equipment manufacturing company with high work risks. The topic was chosen due to frequent violations of safety procedures, such as the improper use of Personal Protective Equipment (PPE) and neglect of Standard Operating Procedures (SOP), which increase the risk of accidents. A qualitative method was used through direct observation, in-depth interviews with 12 shift workers, and field assessments of safety facilities. The findings show that although the company has an Occupational Health and Safety (OHS) management system, non-compliance still occurs. Issues include incomplete PPE usage, disorganized work tools, and unsafe rest habits. Observations revealed potential hazards such as physical (noise), chemical (oil exposure), ergonomic (awkward postures), mechanical (machine use without full PPE), biological, and psychological risks (stress from shift work). BBS is seen as a strategy to connect existing OHS policies with safe work behavior by focusing on mindset and daily habits. The implementation of BBS is expected to reduce accidents and support the creation of a safer, more sustainable workplace.

Abstract

The pH value parameter in the mineral acid water of a coal mining company in South Sumatra is below the set environmental quality standards. The results of measuring the pH value using a pH meter at the inlet are 4.9 which is still below the environmental quality standard of 6-9. Therefore, it is necessary to make efforts to manage the environment before water is discharged into water bodies, one of which is by utilizing kiambang plants as phytoremediation agents in neutralizing mine acid water. This study aims to analyze changes in mine acid water quality and analyze the effectiveness of mine acid water neutralization. The initial quality of mine acid water for pH parameters was 4.9 TDS of 376 mg/l, Fe of <0.1 mg/l, and Mn of 3 mg/l. After the phytoremediation process, the water quality change for pH parameters was 6.6 and Mn was 0.05 mg/l. The neutrality effectiveness of mine acid water increased the pH by 34.69% and the effectiveness of reducing Mn levels by 98.33%. This kiambang plant can be a recommendation for phytoremediation agents for companies considering its availability around the company

Abstract

The TCS3200 color sensor demonstrates limited accuracy under certain environmental conditions, particularly in relation to the distance between the sensor and the object, as well as the surrounding lighting. This study aims to investigate the effects of distance variation (0 cm, 2 cm, 4 cm, and 6 cm) and lighting conditions (bright and dark) on color detection using the TCS3200 sensor integrated with an Arduino microcontroller. An experimental method was employed, with color data converted into the CIELAB color space and analyzed using Delta E as the deviation indicator. The results indicate that the most accurate color readings occur at a distance of 0 cm, where the sensor receives maximum reflected light. Furthermore, measurements taken under dark conditions exhibit more consistent results compared to those under bright lighting, which tends to introduce optical interference. It can be concluded that the TCS3200 sensor performs best at close range and under controlled lighting conditions to ensure accurate and reliable color detection.

Abstract

Indonesia has great potential in the use of geothermal energy as a source of renewable energy. However, its application at the household scale is still very limited. This study designed a geothermal energy conversion system using a shell and tube type heat exchanger that is optimized for domestic needs. This system uses an isopentane working fluid that has a low boiling point, thus allowing the efficient use of low-thermal heat for water and room heating. The simulation results show that this system has a high heat transfer efficiency, with an output temperature of up to 84°C. Thus, this system has the potential to become an economical and environmentally friendly renewable energy solution for households.

Abstract

The processing of natural fibers as raw materials for paper has grown over the past few years. However, the use of composite paper as a printing substrate has several drawbacks. One of them is the low color reproduction quality of printed images on paper made from natural fibers, caused by the insufficient whiteness of the paper. This study aims to investigate the effect of titanium dioxide (TiO₂) addition on the color reproduction quality of composite paper based on sugarcane bagasse fiber. TiO₂ was varied at concentrations of 0%, 10%, and 20%. Printing process was carried out using an inkjet printer with standard CMYK and RGB color patches. After that, the printed results were measured using colorimeter with D65 illuminant. Color distribution analysis was processed using MATLAB software. The results showed that the addition of TiO₂ increased the whiteness of the paper, as indicated by the higher L* values. The color gamut visualization demonstrated that the gamut area expanded as the TiO₂ content increased. This result shows that the addition of TiO₂ affects the color reproduction quality of composite paper.

Abstract

The 2024 National Financial Literacy and Inclusion Survey shows that many Indonesians still do not understand financial fundamentals. This condition contributes to difficulty in managing personal finances. Therefore, financial education from an early age is needed to help people develop healthy financial habits. One effective medium for delivering financial education is a children’s savings book. However, most available savings books are less attractive and do not align with children’s preferences. This study aims to develop a children’s savings book design by integrating educational elements, such as a temporary money storage, based on users’ preferences. The Quality Function Deployment (QFD) approach was used to translate customer needs into product visualization. Data were collected through expert discussion, interviews, and questionnaires distributed using purposive sampling. The results show that the highest-priority feature for further development is the temporary money storage integrated into the book’s cover. This element was then incorporated into the children’s savings book design, while considering both functional and educational aspects.

Abstract

The production process is a crucial aspect in ink formulation, especially violet spot color inks for gravure printing applications, which cannot be accurately reproduced through conventional process printing systems (CMYK). This research aims to optimize the production parameters of violet gravure inks that often exhibit color instability due to delays in the grinding and adjusting stages. The main focus of this research is to analyze the effect of variations in grinding duration, post-grinding aging time, and the amount of raw material on ink color yield, which is evaluated based on density, CIE Lab*, and ΔE parameters. The methodology used was a descriptive experiment on a laboratory scale. The results showed that the optimal treatment combination of grinding for 90 minutes, aging for 48 hours, and the use of 400 grams of material (P3K2L4) produced the highest density value (1.858) and ΔE (0.572), indicating color stability despite quantity variations. This finding indicates that optimization of grinding and aging time contributes to the improvement of pigment dispersion homogeneity and thermal stability of the resin, even without direct measurement of the transition glass temperature (Tg) value.

Abstract

The development of digital printing technology requires machines with high reliability and efficiency. The AccurioPress 6100 is a widely used digital printing machine that offers a speed of up to 100 pages per minute. However, the machine’s Overall Equipment Effectiveness (OEE) at PT. OctoPrint only ranged from 45% to 53%, which is below the industry standard of 85%. This study identifies the gap in machine efficiency and proposes solutions based on OEE analysis involving Availability, Performance, and Quality indicators. The study adopts a descriptive quantitative method, collecting data through direct observation and interviews over a 14-week period. Preventive maintenance strategies were implemented to improve machine performance. The results showed an increase in OEE to 60–63%, supported by improvements in Mean Time To Failure (MTTF) and reductions in Mean Time To Repair (MTTR).

Abstract

Draft Sizing quality is a crucial issue in the sizing department. There were 14,881 total warp breaks woven during the November to December period. This led to low draft sizing quality. This research aims to improve the quality of draft sizing by applying Grey Theory in traditional FMEA. This type of research uses descriptive qualitative research. Data collection techniques using questionnaires, observations and interviews at PT Delta Merlin Dunia Tekstil V. The data processing method in this study uses Grey Theory and FMEA methods. The results of this study indicate that from the sizing process flow there are 7 sizing areas that are potential failures of draft sizing and show that out of 26 priority sequences there are 10 different priorities and 16 the same priority. Determination of improvement priorities is based on the value of the smallest degree of relationship, namely Potential causes PIV is not stable in the size box area with the result of the degree of relationship value of 0.356, Potential causes PIV is not stable in the head stock area with the result of the degree of relationship value of 0.382, Potential Causes Kampas wear in the creel beam stand area with the result of a degree value of 0.477, Potential Causes Gear and Chain wear in the dryer cylinder area with the result of a degree value of 0.453 and Potential Causes The break regulator hole is not symmetrical (pneumatic piston is not aligned) in the creal beam stand area with the result of a degree value of 0.466. This research can recommend the sizing improvement process based on proposed improvements or maintenance schedules on the sizing machine, using Grey Theory in the FMEA method to improve the quality of the sizing draft.
