POLMAN Bandung plaque is a thick product with a relief shape on the surface of the product. The product was originally made using sand casting technology, but now it needs to be developed using high-pressure die casting (HPDC) molding technology. This process was hampered by the absence of technical documentation, so development started from the available sand-casting products. This development was carried out in two stages, first product design, and second tool design. Based on the results of the research carried out, an optimal HPDC design has been produced according to the desired specifications. Product designs are obtained through 3D scanning technology to obtain appropriate geometric data. Then the data generated for mold design and the HPDC process includes a specific casting pressure of 400 bar; casting locking force of 1311 kN; piston diameter of 40 mm; 31.6% fill rate; piston movement (V(x)): first phase 0.497 ms-1 to 307 mm, second phase 2.08 ms-1 to 390 mm. The analysis process in the shot-sleeve simulation has produced the right data for the production process so that machine control is more precise, effective, and efficient.

A test bar is a tool that represents an axis whose position will be tested relative to other machine elements as well as the movement of the axis relative to its own position. With a test bar as a precision tool, the deviation value of a machine's geometry can be determined. In the initial stages of making the spindle test bar, namely determining the design according to ISO 230-1:1996 standards, machine testing tools books and directly observing the Aciera F3 Milling Machine. The stages of making a test bar spindle consist of several machining processes such as the lathe process, heat treatment and grinding process, quality checking, and testing. The results of the quality check showed that there were 4 actual dimensions within the tolerance limits and 3 other actual dimensions had sizes outside the tolerance limits, but sizes outside these limits had no effect on the function of the workpiece being made, so this calibration tool could still be used. For testing the spindle test bar on the Aciera F3 Milling Machine object, there were deviations in eccentricity and parallelism with the transverse direction table of 0.030 mm and 0.011 mm, respectively.

Sorting product system based on dimensional specifications takes a long time and the accuracy is low if done manually. The fatigue factor of production operators results in lowering the quality of work so that the production output becomes of low quality. To overcome this, it is necessary to make sorting equipment that can distinguish the types of products by using inspection camera monitoring which is controlled by Arduino Uno. In this study, a conveyor-shaped prototype was designed which is equipped with a Webcam X6 camera and several proximity sensors to provide input to the Arduino Uno. The camera function detects the product dimensions using the Deep Learning Model SSD-MobileNet v2 method using the Python programming language and is assisted by the TensorFlow and OpenCV libraries. The results of product detection will be processed into input signals to control the Arduino Uno followed by controlling the pneumatic solenoid valves on each product. The result of reading by software is to detect circular objects by 92%, detect triangular objects, which is about 84%, and read square objects, which is about 87%.

This research examines how concept development was carried out to design an omnidirectional wheeled robot base made from extruded aluminum profiles used for moving goods. Concept design goes through a series of stages, that is: identifying problems, determining the function structure, looking for alternative solutions, building concept variations, assessing concept variations and determining the selected concept. After going through all these stages, it was concluded that an omnidirectional robot base can be divided into 2 sub-functions, namely: base frame and electrical energy converter. These two sub-functions have 6 parameters that can be varied, such as: various frame shapes, type of frame material, type of frame bar shape, type of frame connection, type of wheel, type of motor. Alternative solutions can be sought for each parameter, combined and assessed to obtain a variation of the selected concept that meets the list of requirements.

Ragum-125 Polman, is one among other different products produced by Polman Bandung which functions as a clamping device. The Ragum-125 Polman is assembled from several components where the fixed jaw and moving jaw are its main components. For the time being, the production process of the Ragum-125 Polman, especially the fixed and moving jaws, still uses many conventional machines tools and requires many jigs (locating devices) and fixtures (fixing devices). Consequently, the processing time is long. The production process requires fourteen (14) set-ups and many stages of the process from one machine to other machines, which is prone to process errors. CNC machine tools can do many machining operations in a single set-up and can minimize process errors because their movements are numerically controlled. However, to take advantage of CNC machine tools, good set-up planning is needed so that the process can be conducted according to the specifications. This research discusses the planning set-up and choosing the machine tools for machining the fixed and moving jaw of Ragum-125 Polman. It consists of four stages they are, grouping the feature according to the tool approach direction (TAD), selection the set-up datum, set-up formation, and determination the machine tools and sorting the machining operation in every set-up. The result from this research produced 19 rules for guidance the set-up planning processes and yield 2 set-ups for fix jaw and 1 set-up for moving jaw with Mitsubishi CNC Horizontal Milling Machine H4Bn and the drilling machine lodiflex Caser F40 C5 as the machine tools which reduce the number of set-ups from 14 set-up to 3 set-up in machining processes of fix jaws and moving jaws of Ragum-125 Polman.
