Abstract

The selection of a study concentration is an important stage in a student’s academic journey, as it determines the direction of expertise to be pursued. However, many students experience difficulties in choosing a concentration that aligns with their abilities and interests. This study aims to develop a recommendation system for selecting concentrations for students of the Informatics Study Program using the K-Nearest Neighbor (KNN) algorithm. The data used consist of students’ academic scores from semesters 1 to 4, totaling 446 records. The classification process was carried out by dividing the data into 80% training data and 20% testing data. The experimental results indicate that the KNN model with k = 15 achieved the best accuracy of 74.44%. These results show that the KNN method is sufficiently effective in providing concentration recommendations, namely Web and Mobile (WEM) and Intelligent Systems (SCR), based on similarities in students’ academic score patterns. This system is expected to assist students in selecting appropriate concentrations and to serve as a decision-support tool for the study program in academic decision-making.

Abstract

Desa Gendro di Kecamatan Tutur, Kabupaten Pasuruan merupakan sentra peternakan sapi perah dengan populasi lebih dari 3.000 ekor sapi. Namun produktivitas susu masih rendah akibat keterbatasan pakan berkualitas dan ketergantungan terhadap pakan konsentrat pabrikan. Kondisi tersebut diperparah oleh menurunnya ketersediaan hijauan saat musim kemarau dan belum tersedianya teknologi pengolahan pakan yang efisien. Program pengabdian kepada masyarakat ini bertujuan untuk merancang dan menguji awal mesin pakan ternak kering berbasis limbah pertanian lokal guna meningkatkan efisiensi penyediaan pakan dan produktivitas sapi perah. Metode pelaksanaan meliputi analisis situasi, perancangan, pembuatan, dan uji coba awal mesin dengan melibatkan kelompok peternak secara partisipatif. Mesin dirancang dengan tiga sistem utama, yaitu pencacah, pengering, dan pencampur, menggunakan motor penggerak 1 HP dan kapasitas produksi ±50 kg bahan basah per jam. Hasil uji coba awal menunjukkan bahwa mesin mampu menurunkan kadar air bahan pakan hingga 14–15% dan menghasilkan pakan homogen yang tahan simpan hingga satu bulan. Program ini meningkatkan keterampilan peternak dalam pengolahan pakan, memanfaatkan limbah pertanian, serta mendukung implementasi teknologi tepat guna menuju praktik peternakan berkelanjutan dan ekonomi sirkular di Desa Gendro.
Cultivation of Pakcoy (Brassica rapa subsp. Chinensis) Using Hydroponics and Its In Situ Utilization for Consumption: Budidaya Pakcoy (Brassica rapa subsp. Chinensis) Sistem Hidroponik dan Pemanfaatannya Secara In Situ Untuk Konsumsi Septabrina, Canda Kharisma; Sutarman

Abstract

This study aimed to analyze the cultivation process of pakcoy (Brassica rapa subsp. Chinensis) using the Nutrient Film Technique (NFT) hydroponic system, focusing on the effects of nutrient concentration variations on plant growth and quality, as well as its in situ utilization to ensure food safety and nutritional value. The experiment was conducted for 24 days with three nutrient concentration treatments. Observed parameters included plant height, leaf number, fresh weight, vitamin C content, and antioxidant activity. The results revealed that nutrient concentration significantly affected vegetative growth and crop quality. Optimal growth occurred at an electrical conductivity (EC) range of 1.5–2.0 mS/cm, producing an average plant height of 18.5 cm, fresh weight of 110 g, vitamin C content of 42 mg/100 g fresh weight, and antioxidant activity of 55%. Both low and high nutrient levels decreased nutrient uptake efficiency due to ionic stress. In situ utilization of harvested crops resulted in a 5–10% reduction in vitamin C and a 3–8% reduction in antioxidant activity, yet the nutritional quality remained acceptable for fresh consumption. Overall, the NFT hydroponic system proved effective in enhancing growth performance, water efficiency, and nutritional quality of pakcoy, making it suitable for sustainable urban agriculture applications.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilatarbelakangi oleh rendahnya keterampilan menulis mahasiswa dalam pembelajaran Bahasa Inggris serta minimnya pemanfaatan budaya lokal Sasak sebagai sumber belajar. Tujuan kegiatan ini adalah meningkatkan minat, motivasi, dan keterampilan menulis mahasiswa melalui integrasi konten budaya lokal dalam pembelajaran. Metode yang digunakan berupa pendekatan pemecahan masalah dengan desain blended learning yang memadukan pembelajaran daring dan luring. Strategi pelaksanaan meliputi ceramah interaktif, kerja kelompok kolaboratif, serta penilaian antarteman (peer assessment). Evaluasi dilakukan menggunakan kuesioner pre-test dan post-test berbasis skala Likert untuk mengukur persepsi dan sikap mahasiswa. Hasil menunjukkan adanya peningkatan skor rata-rata total dari (5,6) pada pre-test menjadi (7,0) pada post-test. Peningkatan terjadi pada seluruh indikator, terutama minat menulis, kepercayaan diri, dan motivasi belajar. Temuan ini menunjukkan bahwa pembelajaran menulis berbasis budaya Sasak efektif dalam meningkatkan sikap positif dan kualitas pembelajaran mahasiswa.
