Abstract

Abstrak Dunia industri merupakan hal yang tidak terpisahkan dengan proses produksi. Dalam perkembangannya perindustrian dituntut agar menghasilkan produk yang berjumlah besar. Maka dari itu, kita membuat cara manual menjadi lebih modern dimana pengerjaannya lebih mudah dan efisien. Kompor batubara yang ada di industri rumah tangga saat ini masih bersifat manual, belum ada kompor batubara yang panasnya bisa diatur (dinaikkan pada saat dibutuhkan temperatur tinggi dan diturunkan kalau butuh temperatur rendah). Penguasaan teori tanpa diimbangi dengan kegiatan praktek kurang efisien karena mahasiswa tidak mengetahui penerapan dari teori yang dipelajari. Kompor batubara yang berbasis modern dibuat untuk menunjang kebutuhan industri rumah tangga. Pengerjaan pada sistem mekanis meliputi rancangan permukaan ruang pembakaran, rancangan plat bagian atas kompor, rangka kompor briket batubara. Kata Kunci: Kompor Batubara, Rancangan dan Cara Pembuatan, Produktivitas.

Abstract

Abstrak Penelitian ini bertujuan untuk menghasilkan sebuah modul yang layak digunakan pada pembelajaran praktikum Pengelasan di Jurusan Pendidikan Teknik Mesin Fakultas Teknik Universitas Negeri Surabaya. Jenis penelitian ini merupakan penelitian pengembangan. Metode penelitian yang digunakan yaitu pengembangan Dick and Carrey dengan analisis deskriptif kuantitatif. Penelitian dilakukan di Jurusan Pendidikan Teknik Mesin  Universitas Negeri Surabaya. Dalam penelitian ini yang bertindak sebagai responden adalah 3 dosen validator dan  mahasiswa Program Studi D3 Teknik Mesin Produksi Fakultas Teknik Universitas Negeri Surabaya Angkatan 2015 tahun ajaran 2016/2017. Instrumen penelitian yang digunakan untuk mengumpulkan data meliputi : lembar angket dan lembar observasi. Analisis data dilakukan untuk mengetahui tingkat kelayakan dan efektivitas modul Las Busur Listrik yang dihasilkan. Hasil pengamatan pada sampel saat uji coba terbatas tahap pertama (tanpa menggunakan Modul las busur manual yang dikembangkan), diperoleh prosentase aktivitas belajar mahasiswa sebesar 80,008 %, sedangkan hasil pengamatan saat uji coba terbatas tahap kedua (dengan menggunakan Modul las busur manual yang dikembangkan), diperoleh prosentase aktivitas belajar mahasiswa sebesar 90,48.%. Jadi setelah menggunakan modul las busur manual yang dikembangkan, terjadi peningkatan aktivitas belajar mahasiswa sebesar 10,472 %. Kata kunci : Pengembangan Modul, Las Busur Listrik

Abstract

Dip coating is a coating method by immersing the material in a solution for a certain time and then removing the material from the dipping place. Dip coating is an effective coating method that adds strength to each coated material and is accurate. Researchers have developed a microcontroller-based dip coater with an automatic calibration system that has 3 main parts, namely the electrical part, the main workspace part, and the power supply part. To determine student satisfaction in using a microcontroller-based dip coater tool with an automatic calibration system that has been developed, an analysis of student satisfaction with the use of the tool that has been developed will be carried out. The purpose of this study was to determine the level of student satisfaction with the microcontroller-based dip coater tool with an automatic calibration system that has been developed. The data collection method in this study was to use a response questionnaire with a Likert scale. The average score of the four indicators obtained a result of 81.78%, which in this case is a very satisfied category. It can be concluded that the student satisfaction index for the Microcontroller-based Dip Coater Tool with an Automatic Calibration System for Making Thin Layers is Very Satisfied.

Abstract

Small and Medium Industry is an industry that operates in the field of processing raw materials into products that can increase sales value. In the industrial world, business actors are required to process raw materials in large quantities and can reduce costs to make them cheaper. Coal briquette stoves that exist in society have many shortcomings, therefore researchers will make a coal briquette stove by changing the capacity of the briquette fuel container, designing temperature settings, and setting the ideal stove height. With increasing energy needs and the high price of fossil fuels, coal briquette stoves offer a more affordable alternative for small and medium enterprises (IKM) and are more environmentally friendly. This design explains the process of making a stove, from selecting raw materials to optimal design for industrial use. Apart from that, this article also examines the performance and efficiency of stoves in real applications, as well as their benefits in reducing emissions and increasing the productivity of Small and Medium Industries (IKM). The results show that the use of coal briquette stoves not only reduces operational costs but also supports environmental sustainability so that it is feasible to be widely implemented in the Small and Medium Industry (IKM) sector

Abstract

This research is the development of a research support tool, namely Spin Coating. In addition to the high price factor and limited maintenance on the equipment that has been purchased, the researcher wants to design a spin coating tool to support laboratory equipment. Not only to get a relatively affordable price but also to be able to develop homemade tools that have precise measurement capabilities, and good quality results because they use a microcontroller in the tool's work settings. Therefore, researchers created a new design for a spin coating tool with IoT technology to make it easier for laboratory users to monitor it from anywhere and anytime and storage real time. The research method is Research and Development with the stages of design calibration, and testing of tools. From the results of making the tool, the resolution of the tool through the linearity of the sensor used is 99.71% with the power value of each RPM, namely 178.05 RPM/W. The IoT innovation on the spin coating tool runs smoothly using cloud.

Abstract

Dip-coating is essential for coating materials evenly, as imperfections like macropores can impact material properties. This project presents a digitally controlled dip-coating tool that manages withdrawal speed, immersion time, and speed via a microcontroller with an automatic calibration system. Employing a stepper motor and mathematical formula approach, the tool achieves high precision by automatically adjusting dipping parameters, with key metrics including resolution-dependent Vl, calibration speed Vpc and calibration targets tpc, and Sc. The system reaches stable calibration at Vms = Vpc. ensuring rapid, accurate calibration and minimizing errors to 0-2% across 20 to 650 steps. Additionally, the tool’s energy-efficient design consumes less power than other dip-coating systems, providing both durability and accuracy.
