Abstract

Penelitian ini merupakan penelitian eksperimen, bertujuan untuk mengetahui pengaruh memodifikasi sudut kelengkungan dan penambahan turbo cyclone pada intake manifold  terhadap performa (torsi dan daya) mesin 4 TAK. Adapun variabel bebas dalam penelitian ini adalah intake manifold standar, intake manifold sudut kelengkungan kanan 30°, 60°, 90° dan penambahan turbo cyclone pada setiap variasi sudut kelengkungan intake manifol. Untuk variabel terikatnya adalah torsi dan daya. Pengujian dilakukan dengan menggunakan alat dynotest dan pengambilan data dilakukan pada putaran mesin 5250 rpm  sampai 6500 rpm. Teknik analisis data yang digunakan yaitu teknik analisis deskriptif dan analisis regresi dengan statistik MANOVA (Multivariate Analysis Varians). Hasil peneilitian pada variasi sudut kelengkungan intake manifold  menunjukkan bahwa pada putaran 5250 rpm sampai 5750 rpm, torsi dan daya mesin lebih tinggi didapatkan pada penggunaan intake manifold standar. Pada putaran 6000 rpm sampai 6500 rpm, torsi dan daya lebih tinggi didapatkan pada penggunaan intake manifold dengan sudut kelengkungan 60°. Setelah penambahan turbo cyclone, pada putaran mesin 5250 rpm, torsi dan daya lebih tinggi didapatkan saat menggunakan intake manifold standar dan turbo cyclone. Pada putaran 5500 rpm sampai 6250 rpm  torsi dan daya lebih tinggi didapatkan pada penggunaan intake manifold sudut kelengkungan 90° dan turbo cycylone.

Abstract

Interdisipliner merupakan suatu pendekatan yang menggabungkan dari satu disiplin ilmu maupun lebih. Penerapan mata pelajaran Produk Kreatif dan Kewirausahaan (PKK) tentunya tidak hanya satu pendekatan disiplin ilmu, melainkan harus beberapa pendekatan ilmu. Salah satunya adalah pendekatan interdisipliner. Penelitian ini menggunakan pendekatan kualitatif, dengan metode pengambilan data wawancara secara langsung, dokumen pendukung, serta observasi secara langsung. Hasil penelitian akan dibahas lebih lanjut dengan literatur yang relevan. Dari hasil penelitian didapatkan strategi pendekatan satu disiplin ilmu dapat diterapkan di SMK pada mata pelajaran Produk Kreatif dan Kewirausahaan dengan pembuatan jobsheet handle door dan potato spirals, sedangkan strategi pendekatan Interdisipliner dapat diterapkan pada jobsheet alat pengupas kulit telur puyuh otomatis. Pendekatan Interdisipliner pada SMK Teknik Pemesinan dapat diterapkan dengan cara  mengkombinasikan disiplin ilmu (ilmu pada bidang teknik pemesinan, teknik pengelasan, teknik elektronika, dan kewirausahaan) untuk pembuataan jobsheet/produk.

Abstract

Students are always faced with a saturated situation due to uninteresting and monotonous learning models and media. This causes students to pay less attention to the teacher's explanation and causes low student learning outcomes. One way to improve student learning outcomes is to use the Discovery Learning Model with the help of technology-based assessment tools, namely Plickers. The purpose of this research was to determine the effect of Plickers media in the Discovery Learning Model on the learning outcomes of Class XI MIPA students at SMA Kartika XX-1 Makassar. The research method used was quasi-experimental using a post-test only control group design. The research population was all classes XI MIPA SMA Kartika XX-1 Makassar with a total of six classes. The research sample was class XI MIPA 5 as the experimental class and class XI MIPA 4 as the control class. The data collection technique was carried out by giving a multiple-choice test with 20 validated items to obtain learning outcome data. Inferential statistical analysis used the Mann-Whitney test and obtained Zcount = 10.94 and the Ztable value at the 0.05 level of significance is 1.65. So that Zcount (10.94) > Ztabel (1.65), which means that the Plickers media in the Discovery Learning Model has an effect on participant learning outcomes. Class XI MIPA students at SMA Kartika XX-1 Makassar on the main material of salt hydrolysis.

Abstract

Program keahlian teknik pengelasan berpotensi dalam mencetak wirausahawan muda yang mandiri. Namun, integrasi keterampilan teknis dan kewirausahaan menjadi kendala dalam menciptakan lulusan yang siap bersaing di dunia usaha. Kegiatan ini bertujuan untuk menumbuhkan jiwa wirausaha sejak dini pada siswa SMK melalui pendekatan pengabdian terpadu yang dilaksanakan di SMKN 5 Bulukumba dengan jumlah siswa 20 orang. Adapun aspek yang menjadi tolak ukur yaitu pelatihan penggunaan alat ukur mekanik, pengelasan SMAW, alat pengujian tanpa merusak (NDT), dan pelatihan kewirausahaan berbasis unit produksi. Penilaian dilakukan melalui observasi teknis. Teknik analisis data keberhasilan dalam pelaksanaan pengabdian terpadu adalah membandingkan hasil pengetahuan yang diukur dengan menggunakan pretest dan post-test. Hasilkegiatan menunjukkan adanya peningkatan signifikan dari semua aspek, seperti pada aspek pemahaman penggunaan alat ukur mekanik, terjadi peningkatan sebesar 45%. Begitu pun dengan aspek teknik pengelasan SMAW meningkat dari 25% menjadi 85%, aspek penggunaan alat pengujian tanpa merusak (NDT) sebelumnya hanya dipahami oleh 20% siswa, meningkat menjadi 85% setelah mengikuti pelatihan, dan pemahaman tentang kewirausahaan meningkat setelah pelatihan yaitu 85%. Secara keseluruhan, hasil ini mengindikasikan bahwa kegiatan pengabdian terpadu mampu memberikan dampak positif dan terbukti efektif dalam meningkatkan kompetensi dan keterampilan kerja dan kesiapan usaha mandiri siswa.

Abstract

This research discusses work ergonomics based on influencing factors including noise levels, lighting, and temperature to increase worker productivity to achieve production targets and protect workers from work fatigue on an ongoing basis. Systematic analysis is used with initial experiments to evaluate and then optimize parameters such as lighting, noise, and temperature. These factor dimensions can influence workers' skills and influence work productivity and work fatigue. The response surface method methodology is used to optimize parameters. The findings from the research showed that the optimal level with the scenario was that the most suitable noise level was 55.17 dB, the optimal environmental temperature was 26.35°C, and the optimal lighting level reached 2983 Lux. With this combination of conditions, knitting assembly time can be minimized to 12 seconds per unit. The novelty of this research work lies in its application to labor-intensive industries with skilled workers as production personnel where these factors can influence work productivity. The obtained regression model can be widely used for further research and adjust parameters based on various data such as anthropometry.

Abstract

Abstrak. Industri konstruksi di Indonesia menghadapi tantangan dalam hal efisiensi waktu, biaya, dan pengelolaan material, terutama dalam proses pengangkatan beton pracetak (precast). Salah satu masalah yang sering muncul adalah keretakan pada beton saat proses pengangkatan yang disebabkan oleh ketidaksesuaian alat angkat. Dalam rangka memberikan solusi terhadap permasalahan ini, dilakukan kegiatan pengabdian masyarakat di PT. Gelora Konstruksi dengan mengembangkan penggunaan limbah potongan tiang pancang baja (steel pipe piles) sebagai alternatif spreader beam untuk proses lifting beton pracetak. Pemanfaatan material bekas ini bertujuan untuk mengurangi biaya, mempercepat waktu fabrikasi, serta menjaga kualitas konstruksi dengan mengurangi potensi keretakan pada beton. Melalui analisis teknis menggunakan perangkat lunak SAP2000, spreader beam yang terbuat dari limbah potongan tiang pancang dinyatakan aman dengan stress ratio <1. Hasil kegiatan pengabdian menunjukkan bahwa penggunaan material limbah ini menghemat waktu fabrikasi dari 10 hari menjadi hanya 3 hari, serta mengurangi biaya pengadaan material baru. Kegiatan ini memberikan kontribusi nyata terhadap pembangunan berkelanjutan dan praktik konstruksi ramah lingkungan. Kata Kunci: Spreader Beam, Steel Pipe Pile, Efisiensi, Inovasi, Konstruksi
