Abstract

This research is motivated by the need for halal foods in Muslim society with the purpose of avoiding non-halal foods, such as pork, that are sold in the market. Although beef and pork basically have different characteristics, not all Muslims know the differences. Moreover, people nowadays sell beef mixed with pork to obtain more profits. Hence, this paper proposed the implementation of the Pseudo-Nearest Neighbor Rule (PNNR) in classifying images of beef and pork slices based on color features. Based on the image dataset that has been collected, the very significant difference that can be identified visually between beef and pork is the color. The color features were extracted from the image using a color histogram from two different color channels, RGB and HSV. As the result, PNNR that used color features from the RGB channel achieved up to 87.43% accuracy, while using the HSV channel, it can reach up to 93.78% of accuracy. Additionally, this paper evaluates the stability of the proposed method by assessing the variance of classification accuracy across different values of k. It is also noticed that PNNR's performance is relatively consistent for various values of k compared to the traditional kNN algorithm.

Abstract

Terdapat gap antara lulusan LPTK dengan dunia kerja. Hal ini dilihat dari kemampuan dasar mahasiswa untuk menyelesaikan kasus elektronika dan menerjemahkan tantangan ke bentuk proyek. Di sisi lain Jurusan Pendidikan Teknik Elektronika mewajibkan menempuh mata kuliah Sistem Komunikasi Bergerak dan Seluler. Melihat pada materi perlu penguatan dalam upaya penyerapan materi. Hal ini penting karena mahasiswa di semester 4 sudah memasuki masa pengambilan konsentrasi dalam bidang telekomunikasi tetapi belum banyak memiliki pengalaman terkait materi. Penelitan ini menggunakan desain Classroom Action Research atau Penelitian Tindakan Kelas (PTK) dengan model spiral dari Kemmis dan Taggart yang dipadukan dengan model Project Based Learning (PJBL). Subjek penelitian tindakan kelas ini adalah mahasiswa semester empat Prodi. Pendidikan Teknik Elektronika FT UNY, dengan populasi 12 orang terdiri dari 3 perempuan dan 9 laki-laki berlokasi di Laboratorium Telekomunikasi Jurusan Pendidikan Teknik Elektronika dan Informatika FT UNY. Hasil pelaksanaan pembelajaran MK Telekomunikasi Bergerak dan Seluler berbasis model Project Based Learning mampu meningkatkan daya-upaya mahasiswa dalam mendesain proyek. Dalam waktu empat pertemuan menyelesaikan satu proyek, dengan hasil evaluasi kemampuan meningkat 1,75 poin atau setara 8,28%.

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana profil lulusan Profi D3 Teknik Elektronika, penilaian alumni mengenai mutu penyelenggaraan program yang ada di Prodi D3 Teknik Elektronika, dan penilaian stakeholders terhadap kompetensi lulusan prodi D3 Teknik Elektronika.Penelitian ini merupakan penelitian penelusuran alumni dengan pendekatan analisis deskriptif kuantitatif.pelaksanaan tracer study dilakukan dengan konsep tahapan survey menurut Schomburg, yaitu tahap 1 pengembangan konsep dan instrumen, tahap 2 pengumpulan data, dan tahap 3 analisa data serta penulisan laporan. Sumber data dalam penelitian ini adalah 55 orang alumni Prodi D3 Teknik Elektronika dan 10 orang pengguna alumni (stakeholders) Metode pengumpulan data dilakukan dengan penyebaran kuesioner kepada alumni dan stakeholders secara langsung dan melalui google doc. Metode analisis data yang dipakai dalam penelitian ini adalah teknik analisis deskriptif kuantitatif dan evaluatif. Kuesioner penilaian penyelenggaraan prodi D3 Teknik Elektronika oleh alumni dan penilaian kompetensi alumni oleh stakeholders diberikan lima alternatif jawaban, yaitu sangat baik, baik, cukup baik, kurang baik, dan tidak baik.Hasil penelitian menunjukkan bahwa rerata IPK lulusan prodi D3 Teknik Elektronika untuk angkatan 2008 – 2014 adalah 3,27 dan lama masa studi 3 tahun 8 bulan. Sebagian besar masa tunggu alumni dalam mendapatkan pekerjaan ± 3 bulan dan bekerja sebagai karyawan swasta dan teknisi swasta dengan pendapatan 1-3 juta/bulan. Penilaian alumni terhadap layanan administrasi, aspek pembelajaran, pengalaman belajar, dan keterlibatan dalam penelitian dan PPM termasuk dalam kategori baik. Sedangkan penilaian alumni tentang fasilitas perkuliahan tergolong cukup baik. Penilaian stakeholders terhadap alumni dalam hal integritas, keahlian bidang ilmu, kemampuan mengatasi permasalahan, kemampuan berkomunikasi, dan bekerjasama termasuk dalam kategori baik. sedangkan kemampuan alumni dalam berbahasa inggris tergolong cukup baik.

Abstract

The growing demand for autonomous agricultural robots requires compact, energy-efficient 12 V drives. This work designs a 12 V Interior Permanent Magnet Synchronous Motor (IPM PMSM) for field robots with targets of torque >0.8 Nm, speed >1000 rpm, and outer diameter <100 mm. Two rotor options—baselines 0° and 12° skew—were optimized and evaluated via finite-element analysis of torque, back-EMF, efficiency, and thermal behaviour. Compared with 0°, the 12° skew cut torque-ripple RMS from 0.2885 to 0.1390 Nm (−51.8%) and reduced cogging torque by >50%, while peak torque decreased only slightly (1.85 → 1.81 Nm; −2.4%). Efficiency remained high (~89%), power factor improved (0.95 → 0.964), and passive cooling kept temperatures ≤65 °C at 60 minutes. These results indicate that a 12° skew provides a practical design trade-off for low-voltage agricultural PMSMs, delivering smoother, more stable torque for precision tasks such as seeding and spraying without sacrificing overall efficiency.
