Abstract

Google Chat was used in the Faculty of Engineering and Informatics to support academic and non-academic collaboration, with advantages such as real-time, structured communication that is easily accessible by lecturers, students, and administrative staff. This study aimed to analyze the sentiment of Google Chat conversations using the support vector machine (SVM) model to categorize sentiment into positive, negative, and neutral. The data preprocessing process included tokenization, stemming, stop words removal, and text cleaning, using Python with NLTK, Scikit-learn, and Pandas libraries. The study adopted a quantitative approach to analyze sentiment patterns from Google Chat conversations about the quality of services at the Faculty of Engineering and Informatics, as well as experiments to develop and test machine learning models. The preliminary study showed a dataset of 3,735 cleaned data, with invalid or empty elements removed. The data was then categorized into three sentiments: positive, negative, and neutral, based on sentiment analysis of communication text related to services in the academic environment. The next research will focus on selecting the appropriate classification model to provide accurate assessments of the faculty’s service quality.

Abstract

Abstrak: Desa Karangkobar di Kendal memiliki lingkungan alam yang subur, menjadikannya tempat yang cocok untuk peternakan ayam. Ketersediaan pakan alami, udara bersih, dan kualitas air yang baik mendukung kesehatan ternak. Masalah pada Tini Farm, mitra peternakan mikro dalam program ini, hanya terdapat 6 pekerja berpendidikan dasar. Peternak ayam masih mengandalkan pakan konvensional (pur) yang rendah protein dan berisiko mengandung zat berbahaya. Alternatif seperti maggot BSF memiliki nutrisi tinggi dan ramah lingkungan, tetapi budidayanya terkendala teknologi, media wadah, serta suhu dan kelembaban yang kurang optimal untuk pertumbuhannya. Tujuan pengabdian adalah penerapan smart farming maggot BSF yang meningkatkan kualitas ayam siap dijual dalam 1–3 bulan antara 125-200 ekor ayam per siklus serta keterampilan mitra dalam pemantauan pertumbuhan maggot berbasis IoT.

Teknologi ini mampu menekan biaya produksi dan meningkatkan daya saing peternak.Abstract: Karangkobar Village in Kendal has a fertile natural environment, making it an ideal location for poultry farming. The availability of natural feed, clean air, and highwater quality supports livestock health. However, Tini Farm, a micro-scale poultry farming partner in this program, faces several challenges. It only employs six workers with basic education, and the farmers still rely on conventional feed (pur), which is low in protein and may contain harmful substances. Alternative feeds like BSF maggots offer high nutritional value and are environmentally friendly, but their cultivation is limited by technology, container media, as well as suboptimal temperature and humidity conditions. This program aims to implement smart farming using BSF maggots to enhance chicken quality, enabling sales within 1–3 months, producing 125–200 chickens per cycle. It also focuses on improving farmers' skills in IoT-based maggot growth monitoring. Implementation includes coordination with six poultry farmers at Tini Farm, construction, practical training, and assistance in using advanced maggot cultivation technology and IoT-based automatic feeders. Training covers installation, temperature and humidity control, and real-time monitoring. Evaluation involved interviews and a 15-question questionnaire, followed by 3–6 months of additional assistance. Results show 72.2% of the community is interested in maggot farming, with 60.6% increasing production. This technology reduces costs and boosts competitiveness.

Abstract

This study aims to describe students’ self-reflection practices in grammar learning among students of the English Language Education Study Program at Universitas Negeri Padang (UNP). The main focus of the research includes the forms of self-reflection employed by students, their perceptions of its importance, and the challenges they encounter in applying self-reflection throughout the grammar learning process. A qualitative descriptive approach was used, with data collected through in-depth interviews. The interview questions were based on seven key indicators of self-reflection: journaling, talking with peers, practicing mindfulness, engaging in creative expression, spending time alone, attending counselling, and speaking or podcasting. The population of this study consisted of students who had completed all grammar courses in the English Education Program at UNP. The findings indicate that most students engage in self-reflection as part of their learning routine, either through written journals or personal contemplation. Students acknowledge that self-reflection aids in recognizing their weaknesses, correcting errors, and deepening their understanding of grammar. However, several challenges were identified, including a lack of guidance from lecturers, time constraints, and low levels of self-awareness among some students. These findings emphasize the vital role of self-reflection in enhancing the effectiveness of grammar learning and point to the need for institutional support to systematically incorporate reflective practices into the learning process.
