Abstract

Dari banyak macam jenis komoditi produksi pangan, untuk penelitian ini dipilih gabah sebagai objek uji pengeringan. Gabah memiliki ketentuan kadar air pada 14% untuk kondisi kering optimal sesuai dari data Badan Standar Nasional Indonesia (BSNI). Dengan menggunakan metode prototyping sesuai kebutuhan kondisi gabah dan lingkungan produksi sistem prototype dirancang dengan memperhatikan elemen elemen tersebut, digunakan Heater PTC dan Heater “Selimut” sebagai sumber panas utama, fan blower luar dan fan dalam untuk kontrol suhu, sensor DHT22 untuk mengetahui kondisi tabung pengeringan (suhu dan kelembapan), dan sensor YL-69 untuk mengetahui kondisi objek pengeringan. Dilakukan uji kemampuan mekanikal, algoritma, dan pengujian keseluruhan dengan data uji coba sebagai berikut, sensor suhu (DHT22) berpotensi error 0,00~1,74%, sensor kadar air (YL-69) dengan potensi error 0,00~9,14%, dan suhu kerja mulai dari 23°C~77°C. Waktu yang dibutuhkan untuk proses pengeringan agar gabah mencapai kadar air 14% yaitu ~53 menit untuk gabah baru panen 200ml, ~15 menit untuk 100ml, dan ~102 menit untuk gabah terkondisi basah 200ml.

Abstract

This study aims to analyze and compare the accuracy, consistency, and decision-making efficiency between humans and machine learning (ML) algorithms in tabular data classification tasks. The dataset comprises 50 classification cases containing both numerical and categorical features with binary decision labels. Two groups were compared: 10 human participants, and six ML algorithms—Logistic Regression, Support Vector Machine, Random Forest, Decision Tree, k-Nearest Neighbors, and Naive Bayes. ML models were trained on 80% of the data and tested on the remaining 20%, while human participants manually classified all 50 test cases. The results showed that the average human accuracy was 76.2%, while ML algorithms achieved between 78.9% and 91.8%, with Random Forest yielding the highest performance. Human decision-making took an average of 18 seconds per case, significantly slower than the algorithmic predictions completed within milliseconds. Additionally, high variability in human responses indicated lower consistency compared to deterministic outputs from ML models. These findings support the integration of ML algorithms as a decision support or replacement tool in data-driven domains, with the potential to reduce human error in high-stakes environments. Nevertheless, human involvement remains essential in contexts requiring ethical consideration and interpretability.

Abstract

The development of artificial intelligence (AI) is increasingly influencing various aspects of life, including education. However, high school students' understanding of the basic concepts and uses of AI is still relatively limited. Therefore, the AWARE (Awareness of AI) Community Service Activity (PKM) was held at MAN 1 Garut on May 6, 2025. This activity aims to increase students' awareness and initial understanding of the concepts, applications, and potential of AI in supporting the learning process in the digital era. The objective of this activity is to increase students' awareness and understanding of the basic concepts of artificial intelligence (AI), examples of its applications, and the potential and challenges of utilizing AI technology in the context of secondary education. The activity method uses an educational-participatory approach through an introduction to basic AI concepts, presentation of real-world application examples, and simple demonstrations. The activity was complemented by a question-and-answer session and interactive discussion, and was evaluated through a Likert-scale-based satisfaction survey attended by 59 respondents. The evaluation results showed a very positive response from the activity participants. A total of 52.5% of respondents gave a score of 4 for the relevance of the activity topic, while 51.7% of respondents gave a score of 4 for the aspect of the activity's usefulness. In addition, 25.9% of respondents gave the highest score (5), indicating a very good level of satisfaction with the program implementation. In terms of sustainability, 96.4% of respondents expressed their willingness to continue the collaboration in the next activity. All respondents also assessed that the community service activities carried out could be implemented in the partner environment, thus indicating that the PKM AWARE program is relevant, beneficial, and has the potential for sustainable development. In conclusion, this activity successfully achieved its goal of increasing student awareness and understanding of AI and opening up opportunities for further development through learning modules and workshops for teachers.
