Home industry for dynamo repair in Sindang Village, Sindang District, Indramayu Regency, in carrying out its business to repair electric motors, dynamos, and distribution transformers, is done manually using a mechanical counter. The damage that often occurs in this equipment occurs in the coil, usually caused by being overloaded so that it burns. Winding the coils/coils on the dynamo can be done manually or using a winding machine. The type of winding machine commonly used by the dynamo home industry in Sindang Village, Sindang District, Indramayu Regency, still uses a mechanical counter. The accuracy of the number of windings affects the result of the quality of the repairs, apart from the type of winding wire applied. The research method used is quantitative experimental research. So that the result is that the automation process of the dynamo roller machine has been successfully implemented; reading the results using a limit switch still needs to be applied at high rotation (above 1 rpm). This can be corrected by using another sensor (Photoelectric Optocoupler). In the calculation planning results from the semi-automatic dynamo winding machine, the moment of inertia is 49,092.6mm2, displacement is 200.1, loading is 4,924.8 kg.mm, and the most considerable stress is 10,050 N/m2. In contrast, the slightest stress is 0,087 N/m2.

Marking machining processes using lasers have developed in the industrial world. Having high precision and good final quality is one of the advantages of this laser machine. There is a thermal effect generated in the process, so we must understand the impact of the power applied to the material. Carry out the laser marking process with the engraving method on a stainless steel plate material which is given a variation of strength to observe the difference in the final result of a marking. Make as many as 3 pcs of products for each variation of power parameters. The product that has been produced will also be observed for surface roughness on the marking, which aims to find out how deep the food is from the marking. Observation of the surface roughness of the marking on the product using the Surface Roughness Tester 3 times for each product. The results of the data that have been taken will only be observed and entered into the marking results into the roughness class according to ISO or DIN 4763:1981. The marking process uses power variations of 20%, 40%, 60%, 80% and 100%. The results of the marking with the lowest power of 20% produce markings with a roughness value of 0.029µm – 0.110µm and enter into class N3 while the results of marking with the greatest power of 100% obtain a roughness value of 18.210µm – 19.876µm which is included in the roughness class N10. Based on the data obtained in the engraving process with different power variations, it can be interpreted that the higher the power supplied, the higher the roughness value

This study examines the scheduling of the Frame Acid Skid project at the Lombok Steam Power Plant (PLTU) using Gantt Chart and Critical Path Method (CPM). The primary objective is to identify the causes of delays and propose optimization measures for the project duration. Data collected indicates a significant difference between the planned duration (24 days) and the actual project completion time (47 days). The main delays occurred in the welding and painting phases, each requiring an additional 13 days. Contributing factors include the addition of a welding process for materials not covered in the initial contract and specification mismatches in the painting phase. Analysis with Gantt Chart and CPM reveals that enhanced communication, more detailed initial planning, and strict monitoring of project specifications are crucial to minimize the impact of delays on cost and time. The results of this study provide a strong basis for decision-making in similar future projects.

The process of chopping grass for animal feed in Cipicung Village, Sumedang Regency, West Java Province still uses manual methods using simple tools such as machetes and sickles. The use of this tool takes a long time, slowing down the feeding process and requiring human labor. Therefore, the manufacture of a grass chopping machine is needed to simplify the chopping process, make time more efficient and to minimize accidents during the chopping process. The design methods used to obtain data include; field surveys, drawing planning, calculations to determine the components to be used. Based on the calculation results, the machine can chop grass as much as 900 kg/hour or 15 kg/minute. For the rotation of the grass chopper blade needed to chop in 1 minute is 937.5 rpm. While the calculation results of the maximum rotation on the axle pulley are 1800 rpm, then the design can be said to be successful because the rotation of the axle pulley has exceeded the rotation of the chopper blade, which is 937.5 rpm. The simulation results obtained a von misses value of 29.664 N/mm² and a maximum displacement of 0.084 mm and a factor of safety on the frame with a maximum value of 1.5.

ABSTRACT – This study aims to compare the effects of Constant Cutting Speed (G96) and Constant Spindle Speed (G97) modes on the surface roughness of ST 37 and S45C materials in step-turning processes using a CNC lathe. A comparative experimental method was employed, measuring surface roughness (( R_a )) at stepped diameters (16 mm, 24 mm, 32 mm, and 35 mm) with a Mitutoyo Surface Tester SJ-210. Results indicate that G96 mode produces lower surface roughness, with average ( R_a ) values of 2.22 µm (S45C) and 2.27 µm (ST 37) in the N6 class, compared to G97 mode with ( R_a ) values of 3.08 µm (S45C) and 3.03 µm (ST 37) in the N7 class. G96 mode is superior due to its ability to automatically adjust rotational speed based on diameter, whereas in G97 mode, small diameters with high rotation (1273 rpm) increase roughness due to vibration or heat. This study recommends using G96 mode for optimal surface smoothness in step-turning of similar materials. rning of similar materials.

ABSTRACT – Manual tofu cutting is often time-consuming and less efficient, necessitating innovation to enhance productivity. This study aims to design an automatic tofu cutting machine as a replacement for the manual cutting process. The method used is Participatory Rural Appraisal (PRA) with an experimental approach. The design process involves simulations to determine the machine's technical specifications, resulting in a minimum pneumatic piston diameter of 24 mm, an inertia of 88,281.25, and a maximum stress of 0.24 N/mm². Testing shows that the machine can cut 112 pieces of tofu in 3.8 seconds. These results indicate that the automatic tofu cutting machine significantly improves the efficiency and speed of the cutting process compared to manual methods. This research contributes to the development of more efficient food processing technology applicable to small-scale industries.
