Abstract

The purpose of this research was to develop the science of winning track games that can accommodate communication skills. This research is development research using Borg, Gall and Gall research model which quoted from Sugiyono (2013), that there are ten steps in the implementation of research and development strategy. The study sample was purposive, they were students of SMP Negeri 3 Semarang. In a small-scale trial, 16 students were drawn from class VIII, and large-scale trials were conducted in class VII E. Data collection methods used were interviews, questionnaires, observation. The final data analysis includes media and material feasibility analysis, readability analysis of teachers and learners, and communication skills analysis. The conclusion are (1) Science winning track games is a media successfully developed and declared feasible (2) Science winning track games media is effective to identify communication skill of student. It proof by increasing the average score of the students from 66.67% in the first meeting to 100% in the third meeting.

Abstract

This study aims to determine whether there is a relationship between the intensity of using gadgets from the Integrated Science Department of Semarang State University with the e-learning platform during lectures. This study uses a descriptive method and tries to analyze how the use of gadgets in the classroom. The steps to obtain data in the field were carried out by interviewing and distributing questionnaires to 80 students. The intensity of gadget utilization by students in the Millennial Era is classified as frequently used with evidence of 92.5% of respondents stating that they often use gadgets in their daily lives. They use gadgets for social media and look for information related to lecturing materials. The use of gadget-based learning models can be used as a learning strategy to attract the attention of students.

Abstract

Laundry MSMEs are resource-intensive, consuming significant electricity and water while discharging wastewater with high concentrations of detergent residues. Accordingly, assessing their environmental impacts is essential to support sustainable practices in the laundry sector. This study aims to quantify the carbon footprint and water footprint of a laundry MSME, identify the hotspot, and propose mitigation strategies. A gate-to-gate Life Cycle Assessment (LCA) was conducted using SimaPro software. Impact assessment applied IPCC 2021 GWP100 for carbon footprint and AWARE methodology for water footprint. The result shows that laundering 1 ton of clothes generates 5,072 kg CO₂-eq and 687 m³ of water use. The washing process is identified as the main hotspot, contributing 3,470 kg CO₂-eq (68% of total emissions) and 654 m³ (95% of total water use). These findings highlight the need for targeted interventions at the washing stage to reduce environmental impacts and enhance resource efficiency in the laundry sector.
