Abstract

In carrying out the process of grounding coffee manually, some people still rely on manual tools and based solely on the help of human hands, ineffectiveness often occurs. If the coffee beans are processed manually, the process will take quite a long time or if the coffee beans are processed manually themselves, it will produce less than perfect coffee bean powder. It is difficult to regulate the level of maturity or detect the right temperature of the coffee beans to produce the right coffee taste. It also requires a roasting process to a grinding process to turn the coffee beans into coffee powder with the right taste. Based on the problems above, the aim of this research is to simplify the process of converting coffee beans into coffee powder automatically and easily. In carrying out the roasting process to the process of refining the coffee beans, you need to pay attention to three aspects, namely the hot temperature during the roasting process, and determining the weight of the coffee beans when the coffee beans are finished going through the roasting process with a capacity of 100 g. In this research, to control and monitor the temperature and weight of coffee beans using an arduino microcontroller.

Abstract

Perkembangan Internet of Things (IoT) dan Machine Learning menuntut mahasiswa vokasi memiliki literasi teknologi yang relevan dengan sistem elektronika modern. Kegiatan pengabdian ini bertujuan untuk memperkuat literasi teknologi mahasiswa melalui diseminasi pengetahuan berbasis kolaborasi internasional. Kegiatan dilaksanakan di Program Studi Teknologi Rekayasa Sistem Elektronika Fakultas Vokasi Universitas Negeri Malang dengan menghadirkan narasumber dari Universiti Teknologi MARA Malaysia. Peserta kegiatan berjumlah 40 mahasiswa, dan seluruh peserta mengisi angket evaluasi. Metode pelaksanaan meliputi identifikasi kebutuhan, perencanaan kegiatan, diseminasi pengetahuan, diskusi interaktif, serta evaluasi respons peserta menggunakan angket skala Likert 1–5. Hasil evaluasi menunjukkan respons sangat positif, dengan rata-rata keseluruhan skor 4,43 dan mayoritas aspek berada pada kategori sangat baik. Kegiatan ini menunjukkan respons positif terhadap penguatan literasi teknologi mahasiswa vokasi, terutama pada pemahaman konsep, relevansi materi, kebermanfaatan kegiatan, serta kebutuhan tindak lanjut berupa workshop teknis.

Abstract

The development of industrial automation requires vocational students to have relevant competencies in control systems, robotics, and applied electronic technology. This community service activity aimed to support vocational students’ industrial automation competencies through a Control System Engineering workshop that combined expert lectures and technical practice. The activity was conducted over two days at the Faculty of Vocational Studies, Universitas Negeri Malang, involving 32 students. The first day focused on material delivery, discussion, and conceptual reinforcement of control systems, while the second day emphasized technical practice, device demonstrations, and robotics project consultation. Evaluation was conducted through observation, documentation, and participant response questionnaires. The evaluation results showed a very good response, with an overall mean score of 4.46. This activity contributed to supporting participants’ understanding of control systems, robotics applications, and the need for sustainable industrial automation project development.
