Abstract

The activity focuses on fostering independence and personal development among inmates at the Women's Correctional Facility Class IIa Malang through entrepreneurial skills training. This training will equip inmates with basic entrepreneurial skills, including identifying business opportunities, business planning, marketing strategies, and managing small business operations. Additionally, it teaches practical techniques for starting and running sustainable businesses. The entrepreneurial training is conducted through interactive discussions and the presentation of best practices over two days. It involves 50 selected inmates based on their interest in entrepreneurship and nearing release dates. Data analysis is carried out using a qualitative descriptive method. The training results show that the food and beverage sector is the primary choice among participants, with 60% interested in starting businesses in this field. Participants are also deemed to have acquired the skills to identify market opportunities, design effective business plans, and implement operational and marketing strategies. This training is expected to have a significant positive impact on the inmates, helping them build a better future and reducing the risk of recidivism.

Abstract

Ear, nose, and throat disorders are a significant health problem, especially in children. This article discusses the development of an expert system as a diagnosis tool for ENT disorders in children by applying the forward chaining method. The system development was carried out using the waterfall method and built based on android using Kodular. The system can diagnose 36 disorders with 42 symptoms obtained by literature study technique from the book First Aid in Your Home written by Dr Tony Smith and Dr Sue Davidson. The result of this system is able to help the process of diagnosing ENT disorders in children accurately based on knowledge from experts through android applications.

Abstract

Mathematics olympiads require higher-order thinking skills, logical reasoning, and mastery of non-routine material, one of which is combinatorics, a topic often considered difficult by students. Limitations in face-to-face coaching have encouraged the need for structured independent learning media that align with the characteristics of olympiad problems. This study aims to examine the effectiveness of the Math Universe application on students’ conceptual understanding of combinatorics in mathematics olympiads. The study employed a quantitative approach with a one-group pre-test–post-test design. The research subjects consisted of 40 students who were members of the Komunitas Pecinta Matematika (KPM). The research instrument was an olympiad-level combinatorics test administered before and after the use of the Math Universe application. Data were analyzed using a paired sample t-test. The results showed a significant difference in learning outcomes before and after the use of the Math Universe application. These findings indicate that Math Universe is effective in improving combinatorics learning outcomes through independent learning based on self-directed learning and mobile learning. This application has the potential to serve as a supporting medium for mathematics olympiad training, particularly for materials with a high level of complexity.

Abstract

Penentuan jumlah pinjaman nasabah merupakan permasalahan yang kompleks dan bersifat nonlinear karena dipengaruhi oleh berbagai karakteristik nasabah serta risiko kredit macet. Oleh karena itu, machine learning mampu memberikan keunggulan dalam memodelkan hubungan yang kompleks dan menghasilkan prediksi yang lebih akurat serta adaptif berbasis data. Penelitian ini bertujuan untuk membangun model prediksi jumlah pinjaman nasabah menggunakan algoritma Extreme Gradient Boosting (XGBoost) dan TabNet dengan optimasi hyperparameter dengan metode Random Search. Data yang digunakan merupakan data sekunder dengan 4.269 observasi dan 13 variabel. Model dibangun dengan menggunakan pendekatan baseline dan optimasi hyperparameter Random Search, kemudian dievaluasi menggunakan metrik koefisien determinasi (), Root Mean Squared Error (RMSE), dan Mean Absolute Error (MAE). Hasil penelitian menunjukkan bahwa optimasi hyperparameter dengan Random Search mampu meningkatkan kinerja model secara signifikan dibandingkan baseline. Model TabNet dengan optimasi hyperparameter memberikan performa terbaik dengan nilai  mendekati 0,89.

Abstract

Permasalahan pengelolaan sampah di MA Al-Khoirot Malang ditandai oleh belum optimalnya pemilahan dan pengolahan sampah organik, anorganik, serta residu pembalut sekali pakai, sehingga berpotensi menimbulkan permasalahan lingkungan dan kesehatan. Untuk mengatasi permasalahan tersebut, dilaksanakan program pengabdian masyarakat Growcycle (Grow from Recycle) yang bertujuan meningkatkan pengetahuan dan keterampilan warga sekolah dalam pengelolaan sampah melalui pemanfaatannya sebagai media tanam. Program ini menggunakan pendekatan partisipatif yang dilaksanakan melalui tahapan observasi awal, perencanaan, pelaksanaan, dan evaluasi. Kegiatan utama meliputi pembuatan pot tanam dari sampah anorganik, pengolahan sampah organik menjadi kompos, serta pemanfaatan hydrogel dari limbah pembalut sekali pakai sebagai media tanam alternatif. Peserta kegiatan adalah santriwati MA Al-Khoirot Malang yang terlibat secara aktif dalam seluruh rangkaian praktik. Evaluasi dampak program dilakukan menggunakan instrumen pre-test dan post-test, yang dianalisis secara deskriptif dan dengan uji Wilcoxon Signed Rank Test. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan peserta pada seluruh indikator pengelolaan sampah. Rerata skor pengetahuan meningkat dari 12,00 pada pre-test menjadi 16,40 pada post-test, dengan nilai P = 0,000, yang menunjukkan peningkatan signifikan secara statistik. Selain itu, peserta menunjukkan kemampuan praktik dalam pengelolaan sampah dan pemanfaatannya sebagai media tanam. Temuan ini menunjukkan bahwa program Growcycle efektif dalam meningkatkan kapasitas warga sekolah serta berpotensi mendukung keberlanjutan pengelolaan sampah berbasis sekolah.
