The carbon content in coffee grounds can be utilized as a base material or organic pigment in making ink. Organic pigments are made by refining and reducing the particle size of coffee grounds using a screen mesh, and mortar and pestle. The process of making ink is done by mixing coffee grounds with ink-making materials such as distilled water, gum arabic, and arrowroot flour. The process of making this ink is carried out with 4 variations of the composition of coffee grounds, which are 15, 20, 25, and 30 grams. The purpose of this study is to determine the effect of variations in the composition of coffee grounds on the physical properties of the ink, namely viscosity, and on print quality, such as density and L*a*b. The results showed that the addition of coffee grounds pigments affected the density, L*a*b, and viscosity values. The higher the composition of coffee grounds, the higher the density, L*a*b, and ink viscosity values.

A 3D Printing machine is a machine that is capable of printing objects in 3 dimensions, made layer by layer by melting/melting a predetermined material. The material used to make specimens is Polylactic Acid (PLA) filament which has good strength and is easily decomposed in the environment. The resulting specimens were subjected to tensile tests with 3 different thickness variations, namely 2 mm, 3 mm and 4 mm. The results from the tensile test of the 2 mm thickness specimen had the greatest results of up to 43.29 MPa because the layers of the specimen were denser than the 3 mm and 4 mm specimens.

The development of printing machines has undergone an extraordinary transformation along with advances in technology. One of the biggest advances in printing machine technology is the transition from traditional printing methods to digital printing. The production process becomes faster and more efficient. Today's printing machine technology is equipped with advanced features that improve print quality. Modern machines are equipped with intelligent control systems with operating language and instructions in English, human involvement in the production stage is absolute. This research uses descriptive qualitative analysis methods. The comparative study used two countries, Indonesia and Malaysia. As a result, Malaysian students who use English as the medium of instruction have the ability to understand printing machine operating instructions better than Indonesian students. Operating a printing machine has similar abilities to students from two countries. This study underscores the importance of integrating English into engineering curricula, with recommendations for improving Indonesian students' command of English.

Selling physical tickets at tourist destinations is often a problem in the world of tourism. The number of brokers and fake tickets is always the main problem. Physical tickets are very easy to counterfeit and very easy to distribute to irresponsible brokers. As a result, many tourists are deceived and often have to pay twice or even more just because they bought fake tickets. This research analyzes the problems caused by physical tickets and analyzes alternative security printing solutions that can be applied to ticketing systems using descriptive qualitative research methods. The results of this research are that ticketing using security printing will require greater costs and still pose a risk of ticket counterfeiting. Security printing might have benefits if it were given more value, such as embossing for braille letters aimed at blind tourists. However, for greater benefits, digital ticketing will have a smaller risk of counterfeiting and have greater profits.

Forecasting is an important part of every business organization and for every very significant management decision. The purpose of forecasting is to reduce the risk or uncertainty faced by a company in making short-term operational decisions and in planning for long-term growth. The company that is the object of this research is a company operating in the printing sector. Focus on observing receipt products because receipt orders are the highest every month. In the implementation of the production process, there are often shortages of raw materials such as NCR paper or non-carbon required paper so that delivery times are late to reach consumers. The effort used to eliminate/reduce the gap between production and sales is to use a forecasting method which aims to determine product quantity adjustments and when they are needed. Based on data processing using cyclical and linear methods, the method used in calculating the next month's forecast is the Linear method. The linear method has the smallest error values, namely SEE = 1100.57, MAD = 871 and MAPE = 26.34. The total forecast demand for receipt products in November is 4839 pieces

This research examines the mechanical and damping characteristics of Natural Rubber SIR 20 with rubber technical specifications (TSR) when combined with natural zeolite-nanosilica composites. The findings show that the addition of zeolite modified with amorphous silica as a filler in the TSR SIR 20 Natural Rubber compound improves the mechanical properties of the vulcanization product. Dynamic Mechanical Analysis (DMA) is used to investigate the mechanical and damping properties. The results show a significant improvement in the mechanical and damping properties of Natural Rubber Reinforced with Nanosilica Compounds when magnetically modified zeolite is used. In particular, the damping ratio of the Si + Z sample exceeds that of other samples, exceeding ζ > 0.027. These results indicate that nanosilica fillers reinforced with natural zeolites have the potential to be applied to damping devices in considerable industry especially molding machines
