Abstract

Language is an important role in human life because language is a tool to convey information, intentions and goals. English is one of the subjects that plays a vital role in developing students’ language skills, including at the elementary school level. However, in practice, many elementary students still struggle with mastering English vocabulary due to limited teaching methods and low learning motivation. This study aims to improve students’ English vocabulary mastery through the application of a Problem-Based Learning (PBL) model supported by Baamboozle media. The research employed a Classroom Action Research (CAR) approach, conducted in two cycles consisting of planning, action, observation, and reflection stages. The participants were 35 fifth-grade students at UPT SD Negeri 287 Gresik. Data were collected through observations and vocabulary tests.The results indicate that the use of Baamboozle media increased students’ engagement, curiosity, and critical thinking in learning English vocabulary in a more enjoyable and meaningful way. The pre-test results showed that only 31% (11 students) met the Minimum Completeness Criteria (KKM), with an average score of 71.60%. After the intervention, vocabulary mastery improved: in Cycle I, 76.70% of students reached the “Sufficient” category (21 students), and in Cycle II, 85% achieved the “Good” category (28 students). These findings demonstrate that implementing the PBL model combined with interactive digital media can effectively enhance English vocabulary learning at the elementary level.

Abstract

In the manufacturing industry, especially those engaged in the machining process, the results of product quality and tool life are always the main focus of the industry. These factors can be influenced by the friction that occurs between the cutting tool or chisel and the workpiece during the machining process which will cause high cutting temperatures so that the cutting temperature problem must be resolved immediately. This study aims to analyze the effect of machining parameters and conditions on the cutting temperature in the milling machining process. Variations in machining conditions and parameters used include dry, flood, and air-cooling techniques; Spindle speed parameters 500, 800, and 1100 rpm; Feed rate parameters 60, 100, and 140 mm/min. The method used is an experimental method. The cutting temperature was measured using an infrared thermometer. The results of the analysis in this study indicate that the combination of variables in the milling machining process that obtains the most optimal response value to reduce the cutting temperature is the use of the flood coolant cooling technique, then a spindle speed of 800 rpm, and a feed rate of 100 mm/min.
