Abstract

Maksud dari penelitian ini yaitu mencari dampak pelajaran IPA terhadap sikap peduli lingkungan peserta didik. Penelitian ini memakai metode survei (meta-analisis) yaitu menganalisis besarnya dampak pembelajaran IPA terhadap sikap peduli lingkungan peserta didik. Teknik pengumpulan data yang dipakai yaitu teknik literature review dengan cara mencari dan mengumpulkan artikel jurnal yang diambil dari Google Scholar. Data dianalisis memakai analisis statistik deskriptif kuantitatif yang bertujuan untuk mengetahuit nilai effect size. Hasil penelitian ini menunjukkan bahwa: 1) Nilai effect size untuk sikap peduli ligkungan peserta didik pada jenjang pendidikan yaitu tingkat SD, tingkat SMP dan tingkat SMA mendapatkan hasil dengan kategori tinggi 2) Nilai effect size untuk model pembelajaran yang digunakan adalah STM dan PBL dengan kategori tinggi 3) Effect size materi pelajaran yang digunakan adalah materi perubahan lingkungan di tingkat SMA dan bahan pencemaran di tingkat SMA pada kategori sangat tinggi dan tinggi.

Abstract

The purpose of this study was to analyze the effect of the e-module on students' critical and creative thinking knowledge in science learning. This research uses a quantitative descriptive research type with meta-analysis. Data or sources are obtained from articles published in international and national journals that are selected based on categories, namely those related to the influence of e-modules on students' critical and creative thinking knowledge. There were 20 articles used in this study which were then coded and analyzed for their effect size. Based on the results of data analysis, the effect size results for knowledge of critical thinking are in the very high category, for knowledge of creative thinking also has the very high category, meanwhile, the effect of the e-module on students' critical and creative thinking knowledge based on junior high school, senior high school and tertiary education levels has a very high category. Then in the science field, namely Physics, Chemistry, Biology lessons, they have an effect size in the very high category. The results of the analysis show that the effect of the e-module on students' critical and creative thinking knowledge is very high

Abstract

This research is a meta analysis. This study aim to analyze the effect of STEM integrated science innovative learning model on students' critical thinking skills. The data collection technique used is the literature review technique, namely by searching and collecting journal articles taken from Google Scholar. Data analysis used quantitative descriptive statistical analysis which aims to obtain effect size values. Based on a meta-analysis of 20 research articles, information was obtained that in general the STEM integrated science innovative learning model has a high influence on students' critical thinking skills with a value of 1.10. If we look at the level of education, education area and learning model, they show that there are significant differences in each field. The greatest impact of STEM is seen at the college level.

Abstract

Penelitian ini bertujuan untuk meningkatkan efisiensi waktu penggantian roll furnace di PT. XYZ melalui penerapan metode PDCA (Plan–Do–Check–Act) sebagai kerangka perbaikan berkelanjutan. Pada kondisi awal, durasi penggantian mencapai 44 jam per siklus akibat keterbatasan alat angkat, di mana satu unit crane digunakan secara bergantian pada sisi Operator (OP) dan Drive Roll (DR). Kondisi tersebut menimbulkan bottleneck, waktu tunggu tinggi, rendahnya utilisasi tenaga kerja, serta meningkatnya downtime maintenance. Hasil identifikasi masalah menunjukkan bahwa ketergantungan terhadap satu crane menjadi penyebab utama pemborosan waktu, khususnya pada pengangkatan komponen berat seperti motor, reducer, bearing, dan chock. Metode PDCA diterapkan melalui tahapan pengumpulan data historis, observasi langsung proses, analisis kendala teknis, perancangan solusi, serta implementasi perbaikan berupa pemasangan lifting beam dan gantry crane permanen di sisi DR. Evaluasi hasil menunjukkan bahwa penerapan gantry crane memungkinkan aktivitas pada sisi OP dan DR berlangsung secara paralel, menghilangkan waktu tunggu crane, meningkatkan sinkronisasi kerja, serta memperbaiki aspek keselamatan operasional. Hasil penelitian membuktikan bahwa penelitian ini berhasil menurunkan durasi penggantian roll furnace dari 44 jam menjadi 33 jam, dengan peningkatan efisiensi waktu sebesar 25%. Temuan ini mengonfirmasi bahwa pendekatan PDCA efektif dalam mengatasi bottleneck sistem angkat, meningkatkan equipment availability, serta menurunkan downtime maintenance. Kontribusi utama penelitian ini adalah penyediaan model perbaikan teknis yang aplikatif, terukur, dan dapat direplikasi pada sistem maintenance peralatan sejenis di industri manufaktur.
