Abstract

This research aims to distinguish students' perceptions of the TOEIC training given by lecturers for final semester students to help them to achieve the passing grade determined by the campus as a graduation requirement. This research is a qualitative descriptive that revealed the reality of TOEIC training by analyzing relevant data. The selection of research subjects was carried out using a purposive sampling technique on students who had received TOEIC training. Data collection uses a closed questionnaire method which is applied to 186 students from 11 study programs who join TOEIC training. In depth interview was also conducted toward 30 students. The research questionnaire consists of 2 parts, namely: Perception of Learning Quality and Perception of benefits to TOEIC training. The result of this research shows that students have positive perception toward TOEIC training and they agree TOEIC training can improve their listening and reading score. Meanwhile, the interview reveals that students get benefit more from integrated skills approach using authentic material than just simulation and structured practices of TOEIC. This results give insights on future TOEIC Training about its effectiveness to improve students’ English proficiency as well as proposing the best method used in the future training of TOEIC.

Abstract

Perusahaan keramik di Kabupaten Mojokerto menghadapi tantangan pada tahap akhir prosesproduksi sejak operasional Line C dimulai tahun 2023 untuk memproduksi keramik lantai granittipe glaze polish. Masalah utama yang sering muncul adalah tingginya tingkat cacat, terutamapada tahap squaring. Cacat Gumpil Squaring mendominasi sebesar 40%, diikuti Diagonal Linier29%, Chipping 16%, dan Trapesium 15%. dengan adanya masalah tersebut pengendalian kualitassangat ditekankan, salah satunya adalah penerapan metode Six Sigma dengan pendekatanDMAIC. Dari analisis menggunakan diagram fishbone dan metode FMEA, ditemukan limapenyebab utama cacat Gumpil Squaring adalah operator kurang teliti, keramik gumpil sebelumpemotongan akibat guide transportasi aus dan gerinda malfungsi, ketidakrataan antar grindingwheel, pisau grinding wheel gumpil/rusak, serta tidak adanya pengecekan kualitas pada in squaring1. Upaya perbaikan meliputi: pengecekan kualitas in squaring 1 setiap 30 menit, penambahankategori cacat dalam IK, pembuatan form checklist grinding wheel, penggantian guide, penilaianberkala kepada operator, penggantian ulang gerinda dan perbaikan Standard Aus Grinding WheelSquaring 1 dan 2 (R:1-2 dan L:1-2) maksimal sisa 3 mm.

Abstract

Investment casting atau pengecoran logam investasi merupakan salah satu metode pengecoran logam yang banyak digunakan dalam industri manufaktur karena kemampuannya menghasilkan produk dengan bentuk kompleks dan ketelitian tinggi. Meski demikian, proses ini memiliki tantangan tersendiri dalam tahapan proses produksinya, salah satunya adalah potensi terbentuknya cacat porositas yang dapat menurunkan kualitas maupun kekuatan mekanis produk. Cacat porositas umumnya terjadi akibat aliran logam cair yang turbulen, gas yang terperangkap dalam cetakan, Penyusutan saat pembekuan, serta desain gating system dan riser yang kurang optimal. Desain gating system yang meliputi runner dan ingate, serta penempatan dan ukuran riser, sangat memengaruhi kelancaran aliran logam dan proses pengisian cetakan. Penelitian ini bertujuan untuk menganalisis pengaruh variasi dimensi runner, ingate, dan riser terhadap cacat porositas pada produk hasil investment casting. Pendekatan yang digunakan meliputi simulasi pengecoran untuk memvisualisasikan pembentukan porositas, serta metode Taguchi sebagai alat optimasi untuk menentukan kombinasi parameter desain yang menghasilkan kualitas pengecoran terbaik. Dengan menerapkan desain eksperimen Taguchi dan pendekatan Smaller is Better, penelitian ini diharapkan mampu memberikan rekomendasi desain sistem pengecoran yang lebih efisien dan efektif, serta menjadi referensi bagi industri maupun mahasiswa untuk belajar dalam mengurangi jumlah produk cacat dan meningkatkan mutu hasil pengecoran.
