Abstract

One of the industries affected by the growth in the number of internet users and advances in digital technology in Indonesia is online transportation. However, the inDrive company showed the smallest performance, which only reached 4.03 million downloads, this merchant was very far behind its competitors, namely Gojek, Grab and Maxim. InDrive has implemented a unique concept, namely the bidding feature in order to achieve fairness and transparency and maximize services with the SHIELD security feature. Therefore, this study aims to identify the effect of value for money, perceived quality on trust, mediate trust in value for money and perceived quality on customer loyalty, and trust in customer loyalty. This research is a quantitative study, with data sources obtained from online questionnaires distributed to 130 respondents who have used the inDrive application in Indonesia who were analyzed using the Structural Equation Model on SmartPLS. The findings of this study are that perceived quality and value for money has a positive and significant effect on trust, trust mediates perceived quality and value for money on customer loyalty and trust has a positive and significant effect on customer loyalty. Trust is the most significant variable affecting customer loyalty, so inDrive Indonesia management must focus on maintaining consistency and increasing consumer trust

Abstract

Global warming and climate change have increased the frequency and intensity of extreme weather events, significantly impacting human life and the environment. Urban areas such as Kecamatan Panjang in Bandar Lampung City frequently experience flooding due to extreme rainfall and poor drainage systems. This study compares the effectiveness of three deep learning model architectures- Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and Transformers — in predicting rainfall events in Kecamatan Panjang. The data used includes key meteorological variables such as air temperature, dew point, humidity, and air pressure, collected from the Maritime Meteorology Station in Panjang (BMKG) over the past three years. The models were trained using this historical data, with the data divided into training and testing sets. The study results indicate that the Transformer model performs best with the highest accuracy compared to CNN and RNN. The Transformer model efficiently captures long-term dependencies in sequential data, providing more accurate and timely predictions. Model performance evaluation was conducted using accuracy, F1 score, precision, recall, ROC AUC, RMSE, and MAE metrics. The use of deep learning models in rainfall prediction is expected to assist in flood risk mitigation and planning for adaptation to increasingly frequent extreme weather due to climate change. This research significantly advances more accurate and efficient weather prediction systems for urban areas prone to hydrological disasters.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kesadaran merek dan citra merek terhadap loyalitas merek produk Le Minerale pada mahasiswa Universitas Linggabuana PGRI Sukabumi. Penelitiannini menggunakan pendekatan kuantitatif dengan desain penelitian asosiatif. Populasi penelitian mencakup mahasiswa Jurusan Manajemen semester 1 hingga 3 yang telah mengonsumsi produk Le Minerale, dengannjumlah sampel sebanyak 57 responden yang ditentukan melalui rumus Slovin dan teknik purposive sampling. Pengumpulan data dilakukan melalui penyebaran kuesioner, sedangkan analisis data menggunakan metode regresi linear berganda dengan bantuan perangkat lunak SPSS. Hasil penelitian menunjukkan bahwa secara parsial kesadaran merek berpengaruh positif dan signifikan terhadap loyalitas merek, demikian pula citra merek yang terbukti memiliki pengaruh signifikan terhadap loyalitas merek. Secara simultan, kesadaran merek dan citra merek berpengaruh signifikannterhadap loyalitas merek produk Le Minerale. Berdasarkan hasil uji koefisien determinasi, diketahui bahwa kesadaran merek dan citra merek mampu menjelaskan sebesar 57,4% variasi loyalitas merek, sementaraasisanya dipengaruhi oleh faktor lain di luar variabel yang diteliti. Hasillpenelitian ini diharapkan dapat memberikan kontribusi bagi perusahaan sebagai bahan pertimbangan dalam merumuskan strategi pemasaran yang efektif untuk meningkatkan loyalitas konsumen.

Abstract

This community service program aims to accelerate the adoption of Generative Artificial Intelligence technology through the socialization of the use of Google Gemini in four strategic regions of Indonesia. Implementation was carried out specifically at the University of North Sumatra (Medan) to represent the Sumatra cluster, the National Industrial Design Center (Yogyakarta) for the Java cluster, the Integrated Business Service Center/PLUT-KUMKM (Pontianak) for the Kalimantan cluster, and Makassar Digital Valley (Makassar) for the Sulawesi cluster. This program targets three main pillars: increasing the efficiency of teaching tools for educators, digitizing independent financial reports, and optimizing marketing copywriting for MSMEs. The methods used were participatory workshops and technical assistance. Evaluation results showed that the use of Google Gemini was able to reduce administrative time for educators by up to 60% and significantly improve the quality of MSME digital promotional content. This program proves that equalizing AI literacy across Indonesia's major islands is key to strengthening economic competitiveness and the quality of national education
