Crust Breaker is an equipment in aluminum reduction furnace that functions to break the crust on the electrolyte surface. So far, the operational team has identified abnormal crust breakers manually because there is no abnomal crust breaker detection tool available. For this reason, the tool to detect when an abnormal crust breaker occurs is designed by making a prototype crust breaker and measuring the implementation directly on the reduction furnace which can be monitored in real time through the website and providing notifications when abnormal crust breaker conditions occur via Telegram, as well as adding light and buzzer indications in the room. The results showed that the use of toggle switches with normal crust breaker conditions got an average detection response of 86.54% and abnormal crust breaker conditions got an average detection response of 90.51%, as well as direct implementation testing on a reduction furnace with a time setting of less than 10 minutes, the crust breaker provided an actual notification of not touching the electrolyte. Based on these results, the right time to ensure the condition of the abnormal crust breaker is ≥10 minutes.

Springback is a deviation in the bending angle which tends to return to its original position due to the remaining elasticity of the material in the bending area which crosses the plastic material boundary. The five main parameters that influence springback are punch/die profile, work material, material properties, bending technique, and process conditions. This research focuses on the angle of impact which influences the amount of springback. Tests were carried out with punch angles of 120˚, 135˚, and 150˚ using an AIDA direct servo press machine forming the DSF-C1-A series. The results show that the larger the punch angle, the smaller the springback. All angles produce negative springback values, with the 150° strike angle of -0.990° closest to the target angle. The amount of springback can be calculated using a simple linear regression formula. The angular deviation due to springback can be used as a compensation value in making bending tools to obtain the desired bending results.

Student smoking seems to be commonly seen around campuses in Indonesia. However, many studies state that there are negative impacts of smoking on cognitive abilities, physical abilities, health, and so on. This can impact students' ability to study optimally and get the best learning achievements. No study explores the conditions regarding smoking and non-smoking students of Polman Bandung, let alone examining their learning achievements. This research reviews student smokers and non-smokers and their learning achievement. The research method is descriptive qualitative, and questionnaires were distributed to students in May 2023 using a Google Form. There were 207 respondents who filled out the questionnaire, of which 71 were smokers and 136 were non-smokers. The results show that non-smoking students have better academic achievement or GPA than smoking students. It is recommended that campuses minimize the increase in the number of smokers to develop the optimization of students' abilities so that they can improve their learning achievements.

Travel, tourism and hospitality companies have started to adopt RAISA systems in the form of chatbots, delivery robots, autonomous dishwashers, conveyor restaurants, self-service information kiosks and many others [1], [2]. This research focuses on the implementation of deep learning artificial neural networks for object recognition in determining the pose estimation of the manipulator robot and planning the grip on the end effector. A robotic manipulator with 4 degrees of freedom is used to support the estimation of pose angles and an end effector in the form of a 5-finger gripper is used to obtain various grips on objects with random shapes. An RGB camera is used for object recognition with an eye-on-hand configuration, which is linked to the end effector to obtain visual information on objects using the YOLOv3 deep learning algorithm. The end effector works optimally on objects with the basic shape of a tube, rectangular prism, hexagon prism and ten-sided prism with a maximum load that can be lifted of 303 grams with a success rate of 71.23%.

This document reviews the impact of servitization on manufacturing companies' corporate models. It discusses how product-centric firms can transition to service-oriented models by incorporating software services into their offerings. The literature review covers key concepts like servitization, corporate models, value propositions, and organizational changes required. An analytical model is developed to assess the case company's servitization efforts through its CSA software platform. Empirical data from interviews finds the value proposition was inadequate due to inability to demonstrate CSA's benefits. Organizational changes were not properly implemented, leading to lack of resources allocated. The study shows the importance of organizational factors like culture, communication, and strategy alignment in enabling servitization.

DCS Labvolt Festo is a tool as a learning media for water level control systems and water discharge flow using PID control. In this research, the DCS LabVolt Festo plant uses several different components and different controllers such as the Siemens S7-1200 PLC. The method in controlling the water level of two tubes in parallel is using PID control. Radar Level Transmitter and Differential Pressure Transmitter are used as feedback for Tube 1 and Tube 2. Then the application to display the interface that is uses Wonderware InTouch as the interface of all components in the plant. The integration between the DCS LabVolt Festo plant and the Wonderware Intouch application has been successful using OPC KEPServerEX while for the control of the water level in two tubes in parallel using PID with 100% and 50% valve interference gets a fairly stable response with overshoot below 10% for both tubes. For both tubes it is steady state but there are some setpoints that have a steady state error below 5%. To control two tubes, achieve simultaneous setpoint at the same time by adjusting the maximum motor frequency of Tube 2 with a smaller volume according to the setpoint used.

The selection of current in aluminum welding has a significant impact on the quality of the weld joint. Too high a current can cause increased penetration, potential distortion and the risk of overmelting. On the other hand, too low a current can produce a weak weld joint, lack of penetration, and increase the risk of porosity formation. The main focus of this study is to understand the effect of current variations in the Tungsten Inert Gas (TIG) welding process on the strength of 6 mm thick aluminum 6061 welds and using ER4043 filler. The tensile strength and flexibility of the weld joint are very important in construction because they determine the strength, stability, and toughness of the joint to withstand static loads. This study shows that a welding current of 160 Ampere produces the highest tensile strength with an average value of 207.49 MPa, while a current of 100 Ampere has the lowest tensile strength with an average of 132.85 MPa. For a current of 130 Ampere, the average tensile strength was recorded at 154.128 MPa. The bending test results revealed that only welding with a current of 160 Ampere met the standard criteria, while currents of 100 Ampere and 130 Ampere experienced cracks and fractures that exceeded the standard limits. Microstructural analysis showed that in the heat affected zone (HAZ), the Mg2Si phase was most dominant at a current of 160 Ampere, which also applied to the weld metal. This Mg2Si phase contributed to the increase in the mechanical strength of the material. Based on these results, this study emphasizes the importance of choosing the right current in welding aluminum 6061, with a current of 160 Ampere as the best choice to produce strong weld joints.
