Abstract

Abstrak Pada Laboratorium Fabrikasi Teknik Mesin Unesa terdapat pengerol plat konvensional yang penggunaanya masih menggunakan sumber tenaga manusia. Untuk memperbaiki kinerja alat roll plat ini, penulis ingin membuat atau merancang sistem kerja yang manual menjadi sistem elektrik. Metode yang digunakan adalah R&D (Research and Development) yaitu perancangan berbasis eksperimen yang mengacu pada spesifikasi komponen dan jenis komponen yang akan digunakan. Berdasarkan perancangan yang telah dilakukan yaitu dengan spesifikasi mesin panjang 1000 mm x lebar 510 mm x tinggi 950 mm, motor penggerak 1 PK 3 fase dengan kecepatan 1400 rpm. Sistem transmisi menggunakan reducer perbandingan 1:60 dan ukuran sprocket diameter 125 mm dan diameter 250 mm, serta roda gigi berukuran diameter 50 mm dan diameter 150 mm. Roller mesin berukuran panjang 600 m dan diameter 85 mm, serta poros berukuran panjang 800 mm dan diameter 35 mm. Kapasitas mesin yaitu tebal plat 0,5 mm sampai 5 mm dengan lebar plat 550 mm dan panjang plat sesuai kebutuhan. Kata Kunci: Rancang Bangun, Mesin Otomatis, Mesin Pengeroll

Abstract

Jurusan Teknik Mesin Unesa merupakan salah satu jurusan yang ada di Fakultas Teknik. Jurusan teknik mesin mempunyai beberapa lab yang digunakan untuk mahasiswa teknik mesin praktikum. Ada 15 lab yang ada dijurusan teknik mesin salah satunya lab fabrikasi. Pada lab fabrikasi banyak peralatan fabrikasi yang tersedia dan dapat digunakan, namun masih banyak yang menggunakan tenaga konvensional. Salah satunya mesin pengeroll plat yang digunakan untuk membuat lengkung pada plat., namun penggunannya masih menggunakan tenaga manusia. Disini penulis mempunyai ide untuk membuat mesin pengeroll plat namun menggunakan motor sehingga mengubahnya menjadi semi otomatis Metode rancang bangun yang digunakan dalam analisa hasil mesin pengeroll plat ini berupa rancangan hasil uji coba dengan memanfaatkan berbagai macam sampel. Sampel pada analisa hasil mesin pengeroll plat semi otomatis ini berupa perbedaan ketebalan, perbedaan waktu dan perbedaan beban yang diterima. Hasil analisa mesin pengeroll plat semi otomatis yang sempurna ditentukan dari segi bahan sampel plat, waktu pengerollan dan ketebalan sampel plat yaitu menghasilkan sampel plat dengan ketebalan 0.5 berbahan dasar galvalum dapat diuji coba namun setelah diuji coba sampel kembali seperti semula karena bahan sampel plat terlalu tipis. Sampel plat dengan ketebalan 0.7 mm menghasilkan sudut kelengkungan 180derajat, 235 derajat, 330 derajat masing masing membutuhkan waktu 30detik, 40detik dan 50 detik, ketebalan plat 1 mm menghasilkan sudut kelengkungan 200derajat, 255 derajat, dan 360 derajat, masing masing membutuhkan waktu 30 detik, 40 detik, 50 detik. Kata Kunci : mesin pengeroll plat semi otomatis, analisis teknik, tujuan analisis, metode rancang bangun.

Abstract

The ceremony is a tradition of the community historically has a meaning to give thanks to God and the ancestors of the local community. In accordance with the development of modern society, a culture and tradition begin to slowly shift. This confusion can be seen in the ritual ceremony of tandak kissing (Java language: traditional singer). The tandak kissing ceremony is a traditional ceremony carried out by the ethnic Madurese people who have lived in Menganti Gresik for a long time ago.  The ritual ceremony has undergone a shift, because it can be known by the loss or decrease of the community to carry out and keep the ceremony well as a result of social changes. This research method used a qualitative descriptive approach to find out how far the shift occurred and what caused the ceremony to become extinct. This theory used ethnolinguistic studies, which combine linguistic and anthropological aspects to understand the relationship between language and culture. Based on the results of the study, it can be seen that the shift of ritual ceremonies is an effort to find out the extent to which the loss of culture and tradition can occur so that the younger generation can maintain and preserve as a legacy of local wisdom from their ancestors.

Abstract

Many studies have examined the effect of project-based learning on students' scientific and critical thinking skills, but no research has examined the effect size of the Deep Learning-based PjBL model on students' scientific and critical thinking skills in Indonesia. The integration of deep learning principles into Project-Based Learning (PjBL) gave birth to the Deep Learning-based PjBL model that encourages students to construct knowledge through real projects, continuous reflection, and collaboration. This study aims to determine the learning model of project-based learning based on deep learning on students' scientific and critical thinking skills. This type of research is quantitative research with a meta-analysis method. The inclusion criteria in this study are research data derived from journals indexed by Sinta or Scopus, articles published in 2021-2025, research must be experimental or quasi-experimental methods, relevant research, data obtained through the Google Scholar, ERIC, ScienceDirect, and Taylor of Francis databases, and published journals have complete data to calculate the effect size value. Data analysis using the JASP application. This study analyzed 17 relevant articles. The results concluded that the summary effect size value was d = 0.88; t = 8.26; p < 0.005, a high effect size category. These findings explain the significant influence of the deep learning-based PjBL model on students' scientific and critical thinking skills in learning. aspects to tackle this issue, particularly in low- and middle-income countries.

Abstract

This study examines the role of deixis in shaping persuasive sociopreneurship communication on Instagram and TikTok, focusing on six posts (three from each platform) by the Indonesian sociopreneur @aldwinnv. Deixis, as a pragmatic linguistic feature, situates utterances in relation to the speaker, audience, and context, making it essential for persuasive strategies in digital communication. Employing a qualitative descriptive approach within the pragmatic discourse framework, the study identifies personal, temporal, spatial, discourse, and social deixis in the data. Findings indicate that personal deixis, particularly saya (I) and kita (we), builds relational intimacy and credibility. Temporal deixis, such as sekarang (now) and hari ini (today), creates urgency and motivates immediate action. Spatial deixis (e.g., di sini, tempat ini) authenticates the speaker’s experience by grounding narratives in real contexts. Social deixis (e.g., teman-teman, sahabat, bro) varies between platforms, reflecting formality on Instagram and casual solidarity on TikTok. Discourse deixis (e.g., seperti yang saya bilang tadi) strengthens coherence in motivational storytelling. These findings show that deixis operates as a persuasive device that enhances ethos, pathos, and communal identity in sociopreneurship content. The study contributes to digital pragmatics by demonstrating how subtle linguistic cues support persuasive entrepreneurship narratives and offers pedagogical implications for media literacy and entrepreneurship education.
