Abstract

ABSTRAK                                                                                     Giga Catering, unit usaha berbasis pesantren yang bergerak di bidang jasa boga, menghadapi berbagai kendala dalam pengelolaan usaha, antara lain keterbatasan pemasaran digital, ketiadaan SOP higienitas, pencatatan pesanan secara manual, serta keterbatasan peralatan produksi. Kegiatan dilaksanakan pada Juli–Agustus 2025, melibatkan 18 peserta yang terdiri atas pengurus koperasi dan penjamah makanan Giga Catering. Intervensi dilakukan melalui tiga sesi pelatihan terintegrasi, meliputi sosialisasi, penyuluhan, workshop, dan praktik langsung. Evaluasi dilakukan melalui pre-test dan post-test yang menilai tiga dimensi utama: pengetahuan, perilaku, dan implementasi. Hasil menunjukkan peningkatan signifikan, yaitu pengetahuan naik 20% pada aspek digitalisasi dan higienitas, perilaku meningkat 25% pada kedua aspek, serta implementasi bertambah 45% untuk digitalisasi dan 25% untuk higienitas. Hasil ini menegaskan peningkatan kompetensi teknis sekaligus perubahan perilaku peserta yang konsisten dengan standar operasional. Program ini berhasil mewujudkan konsep smart catering berbasis pesantren yang profesional, higienis, dan adaptif, serta berpotensi direplikasi pada unit usaha serupa dalam ekosistem ekonomi pesantren. Kata kunci: Transformasi Digital; Higienitas Penjamah Makanan; Smart Catering; Pemberdayaan UMKM ABSTRACTGiga Catering, a pesantren-based culinary enterprise, faces various management challenges, including limited digital marketing, the absence of hygiene standard operating procedures (SOP), manual order recording, and limited production equipment. The program was implemented from July to August 2025, involving 18 participants, comprising cooperative administrators and food handlers of Giga Catering. Interventions were conducted through three integrated training sessions, including socialization, counseling, workshops, and hands-on practice. Evaluation was carried out using pre-tests and post-tests assessing three main dimensions: knowledge, behavior, and implementation. The results indicated significant improvements, with knowledge increasing by 20% in digitalization and hygiene aspects, behavior improving by 25% in both areas, and implementation rising by 45% for digitalization and 25% for hygiene. These findings confirm the enhancement of technical competencies alongside behavioral changes consistent with operational standards. The program successfully established a professional, hygienic, and adaptive pesantren-based smart catering model, which holds potential for replication in similar business units within the pesantren economic ecosystem. Keywords: Digital Transformation; Food Handler Hygiene; Smart Catering; MSME Empowerment

Abstract

The advancement of machine learning, particularly in time-series analysis, has created significant opportunities for improving the accuracy of stock price prediction. However, the volatile nature of financial markets and the complexity of temporal patterns often hinder the ability of single models to deliver consistent and optimal results. To address these limitations, this study proposes a hybrid approach by integrating three popular algorithms—Long Short-Term Memory (LSTM), XGBoost, and LightGBM—through a stacking ensemble method. The dataset used consists of daily stock prices of Apple Inc. (AAPL) for the period 2014–2024, obtained from Yahoo Finance. The research process includes preprocessing, the construction of time-series datasets using windowing techniques, training of single models, and the application of ensemble stacking. Experimental results reveal that LSTM achieved the best performance among the single models, with a MAPE of 3.70% and R² of 0.9204, demonstrating its ability to capture long-term temporal dependencies. In contrast, XGBoost and LightGBM performed poorly in recognizing sequential patterns, resulting in negative R² values. The combination of all three models through stacking ensemble significantly improved prediction accuracy, achieving a MAPE of 2.57% and R² of 0.9693. These findings confirm that integrating LSTM, XGBoost, and LightGBM not only enhances predictive accuracy but also improves model stability, while contributing to the scientific development of hybrid machine learning methods in stock market analysis.

Abstract

This community service program aims to enhance MSME owners' understanding of marketing strategies, digital marketing, local cultural identity–based branding, and standard operating procedure (SOP)-based business management to strengthen the competitiveness of Plered Ceramic MSMEs. The program was implemented through a series of awareness sessions, training, mentoring, and evaluation activities. The training covered market segmentation, targeting, and positioning (STP), online selling strategies, marketplace utilization, digital promotion, product content development, and the preparation of simple standard operating procedures (SOPs). Program effectiveness was evaluated using pre-test and post-test instruments consisting of 10 knowledge indicators. The data were analyzed using descriptive quantitative methods by calculating the percentage of correct responses for each indicator, the mean pre-test and post-test scores, and the difference between the two. The results demonstrated a substantial improvement in participants' understanding, with the mean score increasing from 51.11% to 94.45%, representing a gain of 43.34 percentage points. Improvements were observed across all knowledge indicators, with the greatest gains in participants' understanding of marketplace utilization and the concept of standard operating procedures. Overall, the program represents an important initial step toward strengthening digital marketing capabilities, reinforcing consistent branding practices, and promoting more structured business management among Plered Ceramic MSMEs.

Abstract

Mayar adalah platform untuk mengelola transaksi pembayaran online, terkhusus untuk menerima transaksi donasi, webinar, event, produk digital dan lain sebagainya. Mayar diciptakan untuk merchant berjualan dan dapat membuka peluang bagi mahasiswa yang ingin bergabung untuk internship/magang. Program magang dilakukan secara work from home (WFH) namun terdapat permasalahan yaitu pelaporan leads (calon klien/prospek), kegiatan calon leads masih belum terdokumentasi dengan baik, serta proses monitoring masih dilakukan dengan menggunakan spreadsheet. Hal tersebut membuat pembimbing merasa kesulitan untuk memonitoring progress para peserta magang. Berdasarkan permasalahan tersebut maka diperlukannya pembuatan sistem informasi monitoring untuk membantu pembimbing dalam melakukan monitoring terhadap kegiatan magang secara real time serta dapat memindahkan sistem jobdesk magang mahasiswa yang masih dilakukan pada spreadsheet menjadi sistem informasi terpusat. Metode yang digunakan dalam pengembangan perangkat lunak adalah metode waterfall. Hasil penelitian ini dapat mempermudah pembimbing dalam memonitoring progress magang agar terdokumentasi dengan baik sehingga kegiatan calon leads ini dapat menjadi informasi yang terpusat.
