The research objective was to determine the validity of the due diligence worksheet based on an ecological project to improve science process skills. To find out the practicality of ecological project-based practicum worksheets to improve science process skills. The study method developed using Research and Development (R&D) consists of several stages of research implementation, namely the first stage is preparing for the Experiment/Preliminary Design. The second stage of product creation (process), includes: assessing students' abilities in selecting and using materials, tools and techniques. Next, the third stage of product assessment (appraisal), includes: assessing the products produced by students according to the established criteria. The target research subjects were 30 FKIP UNSAM Biology Education students. Data collection techniques carried out included using tests, observation sheets, questionnaires, interviews, assessment of Practicum Worksheets, portfolios, field notes and assessment rubrics. The results of this research show that the product feasibility validation test with an average score of 88.22% is declared very valid, while the practicalization test with an average score of 84.2% is declared very valid. So it can be concluded that the Practical Worksheet product is suitable for use for Biology practical learning activities

In recent times, the issue of plastic recycling has become one of the leading issues of environmental protection and waste management. Polymer materials have been found an application in many areas of daily life and industry. Along with their extended use, the problem of plastic waste appeared because, after withdrawal from use, they became persistent and noxious wastes. The possibility of reusing polymeric materials gives the possibility of valorization a second life and enables effective waste utilization to obtain consumable products. The 3D printing market is a well-growing sector. Printable filaments can be made from a variety of thermoplastic materials, including those from recycling. The production of filaments for 3D printers from recycled polymers is the alternative present approach. The possibility of recycling basic thermoplastic materials. Key Words: 3D Printing, Filament, Recycling, Polymer, Plastic, Waste Management, Extruder.

The manufacturing process in the automotive industry is in dire need of resistance spot welding machines. Because it was easier to use, highly effective, and effective in functioning. However, there were sometimes still connection problems that were still of poor quality, both nuggets and areas that are subject to electrode pressure. To get a quality welding connection, a machine was needed that was able to carry out good material preparation in the form of sanding, able to set the welding current analogously, able to set the time with an automatic timer, able to apply pressure on the electrode measurably during the welding process. The research aimed to design a prototype of resistance spot welding material preparation that could adequately carry out material preparation and welding using a Bluetooth system connected to a mobile phone. The research methods carried out were as follows: first, designing the machine using Autodesk Inventor software, then the device was made with a focus on material preparation prototypes, then the machine elements were made for the material clamping rail, then the machine elements in the control section using Bluetooth connected to the mobile phone, the machine was tested, then the connection quality testing process was carried out on the tensile testing machine. The results showed that the design results had been made using elbows and iron plates with threaded rails with a length of 650 mm, which became material clamping rail grooves with a drive using window motors controlled by Bluetooth on the Arduino circuit. The test results of welded joints show that the roughness is 0.20 μm which has the highest tensile strength.
