Abstract

The development of information technology has had a big impact on human life. The impact of the development of information technology is the internet, which reaches all circles of society. The development of the internet has positive and negative impacts. The positive impact of the internet is that it helps humans get information quickly and can be reached anywhere. Meanwhile, the negative impact of the internet itself is the existence of cybercrime. There are various modes of cybercrime, one of which is the most often encountered by the public: adware-type malware, often known as malicious online advertising. The purpose of this study is to determine the factors that influence public awareness of cybercrime in adware. This research uses a quantitative method approach with sample criteria for respondents who live on Java Island with an age range of 18–45 years and actively use the internet. The data from the distributed questionnaires was processed with the partial least squares structural equation model (PLS-SSEM) using SmartPLS 4. The results obtained showed that of the 10 hypotheses that had been proposed, 8 were accepted. Based on these results, there are factors that influence public awareness of cybercrime, including the use of social media, cybercrime information and news, cybercrime law enforcement, and adware knowledge. Furthermore, adware knowledge is influenced by cybercrime information, news, and social media usage.

Abstract

Pneumonia is a leading cause of child mortality worldwide, and its diagnosis often relies on chest X-ray interpretation, which is prone to human error. This study aims to optimize a Convolutional Neural Network (CNN) model based on transfer learning using the DenseNet-121 architecture for pneumonia classification in chest X-ray images. The model was trained on a Kaggle dataset consisting of two classes: Normal and Pneumonia. Preprocessing included class balancing and data augmentation. Five fine-tuning strategies were tested, ranging from training only the classifier to unfreezing the entire pretrained layers. Evaluation metrics included accuracy, precision, recall, F1-score, and ROC-AUC. Results showed that the strategy of unfreezing Block 3–4 yielded the best performance with 94.39% accuracy, 95.61% F1-score, and 98.04% ROC-AUC. This study demonstrates that selective fine-tuning strategies significantly improve classification performance compared to training only the classifier or the entire network.

Abstract

This study aims to measure the acceptance level of the warehouse module within the ERP system implemented at CV Kalingga Keling Jati, utilizing the extended UTAUT model. The analyzed variables include performance expectancy, effort expectancy, hedonic motivation, trust, behavioral intention, use behavior, and one moderator variable, education. The results indicate that effort expectancy, hedonic motivation, trust, and behavioral intention significantly influence users' intention and behavior in utilizing the warehouse module. However, performance expectancy and the moderator variable education do not show significant influence. This research also highlights the importance of effective warehouse management systems to minimize errors in inventory management and enhance operational efficiency within the company. With the implementation of an ERP system integrated with IoT, CV Kalingga Keling Jati aims to improve user satisfaction and reduce resistance to new technologies. The findings provide insights for other companies considering similar technology adoptions in their warehouse management.Furthermore, the study emphasizes the need for continuous evaluation and adaptation of technology to align with user needs and organizational goals. By understanding user acceptance, organizations can better tailor their systems to enhance productivity and foster a positive technological environment. This study contributes to a deeper understanding of the factors influencing technology acceptance in the business context, particularly in the manufacturing sector, and offers a foundation for future system improvements.

Abstract

Perubahan status UNNES dari PTN BLU menjadi PTN BH dengan dasar hukum Peraturan Pemerintah Republik Indonesia Nomor 36 Tahun 2022 tentang Perguruan Tinggi Negeri Badan Hukum Universitas Negeri Semarang tertanggal 20 Oktober 2022 yang dikuti perubahan visi, misi, dan tujuan UNNES. Selain perubahan visi, misi dan tujuan juga perubahan tata kelola aset.  Pengelolan aset PTN BH UNNES dapat dikatakan mengalami kenaikan status pengelolaan aset. Kenaikan status pengelolaan ini dulu sebagai pengelola adalah Kemenkeu dengan pengguna Kemendikbudristek dan UNNES sebagai kuasa pengguna, berubah menjadi pengelola adalah tingkat universitas dan pengguna bagi anak satker di lingkungan UNNES. Perubahan kenaikan status menjadikan UNNES memiliki keleluasan besar untuk mengelola asetnya sendiri namun juga memiliki tanggung jawab besar yang harus dijalankan. Peningkatan status pengelolaan aset PTN BH UNNES harus diimbangi kemampuan sumber daya manusia yang mengelola aset dan sistem informasi yang handal sebagi sistem pembantu dalam pengelolaan aset.  Pada tahun 2017 Seksi Aset bersama DSIH melakukan pembuatan sistem My-unnes keuangan konten aset. Perubahan sistem pengelolaan aset yaitu myunnes-keuangan konten myaset unnes tentunya mempengaruhi proses kerja pengelolaan aset dalam menjalankan tugasnya sehari-hari khususnya dalam mendata dan menginventarisasi atau penatausahaan serta laporan aset yang ada di UNNES. Penerapan sistem myaset UNNES diharapkan juga dapat mempermudah dalam penyampaian informasi laporan keuangan khususnya dalam laporan aset UNNES dan penggunaannya dapat mendukung kinerja organisasi semakin baik lagi. Konten Myaset UNNES adalah sistem baru penganti siagung yang mengadopsi sistem sakti. Operator pengelola aset di unit saat ini dapat dipastikan tidak memiliki pengalaman dalam pengelolaan aset dengan sakti atau ke MyUNNES-Keuangan konten aset. Oleh karena itu diperlukan pelatihan agar pengelola aset/operator aset di unit mampu menjalankan sistem my aset tersebut dengan baik. Selain itu juga perlu ada study lebih lanjut tentang fleksibilitas sistem MyUNNES-Keuangan konten aset dalam membantu mempermudah pengelola/operator aset dalam bekerja. Pemakaian myaset akan tergantung sejauh mana kepuasan dari penguna/operator. Kepuasan ini diwujudkan dalam penilaian sejauh mana efektivitas sistem.

Abstract

Purpose: Breast cancer remains a significant cause of mortality among women, requiring accurate diagnostic methods. Traditional classification models often face accuracy challenges due to missing values and irrelevant features. This investigation advances the classification of breast cancer through the amalgamation of the C4.5 algorithm with K-Nearest Neighbor (KNN) imputation and Relief feature selection methodologies, thereby augmenting data integrity and enhancing classification efficacy. Methods: The Wisconsin Breast Cancer Database (WBCD) was the core reference for evaluating the proposed methodology. KNN imputation addressed missing values, while Relief selected the most relevant features. The C4.5 algorithm executed training by utilizing data segregations in the corresponding proportions of 70:30, 80:20, and 90:10, with its efficiency gauged through a range of metrics, particularly accuracy, precision, recall, and F1-score. Result: This innovative methodology achieved the highest classification accuracy of 98.57%, surpassing several existing models. Particularly noteworthy, the strategy being analyzed exhibited remarkable success relative to PSO-C4.5 (96.49%), EBL-RBFNN (98.40%), Gaussian Naïve Bayes (97.50%), and t-SNE (98.20%), demonstrating associated advancements of 2.08%, 0.17%, 1.07%, and 0.37%. These results confirm its effectiveness in handling missing values and selecting relevant features. Novelty: Unlike prior studies that addressed missing values and feature selection separately, this research integrates both techniques, enhancing classification accuracy and computational efficiency. The findings suggest that this approach provides a reliable breast cancer diagnosis method. Future work could explore deep learning integration and validation on larger datasets to improve generalizability.

Abstract

Online prostitution is an example of cybercrime which is increasingly happening in today's digital era. Even though online prostitution cases have been well documented, in Indonesia itself there is no criminal law regulation that specifically addresses prostitution cases that occur on social media. Likewise, there is a lack of research that discusses the process of how online prostitution cases can occur from start to finish and social media interventions in these cases. The average previous research only focused on law violations that occurred at the final stage or at the exploitation stage. This indirectly ignores the role of social media in the process of building trust between perpetrators and victims (trust building), the process of trading or advertising (advertising), and the process of transactions between perpetrators and potential buyers (transactions). Therefore, in this study the author will discuss the role of technology in online prostitution cases and their relationship with criminals, victims and members of the police. The research design used by the author is Research & Development Level 1. The data in this study were obtained using in-depth interviews with informants and analysed by a deductive approach adapted from Nunamaker's research. Based on the results of the data analysis that has been carried out, the author finds that the social media most used by the actors is the MiChat application as much as 44%, Facebook 26%, WhatsApp 12% and other applications as much as 18%. In addition, this research also produces a conceptual model that describes the various processes that occur in online prostitution cases and the role of each social unit and social media. The conceptual model has been tested and validated by experts using the rating scale method. Obtained a percentage value of 86.67%. The results of this assessment prove that the conceptual model created is very feasible.

Abstract

The purpose of the community service program under the Regional Empowerment scheme is to strengthen sustainable agribusiness for durian and coffee commodities through cultivation technology in Brongkol Village, Jambu District, Semarang Regency. The focus of the community service program is to address regional problems, namely economic problems. The problem-solving method is carried out in a participatory manner through socialization activities, training, technology application, mentoring, monitoring, and evaluation, as well as program sustainability in the Brongkol Village area. There are two target partners who receive benefits, namely Ajuning Tani (durian commodity) and Karya Bakti I Farmers Group (Robusta coffee commodity). The focus of the community service program for Ajuning Tani partners is addressing economic problems while Karya Bakti I Farmers Group partners are addressing tourism problems. The economic problem faced by partners is the lack of derivative products that can provide added value and increase income. The tourism problem faced by partners is the lack of readiness of superior products to become a pioneering tourism village. The solution designed to address the problem is carried out through several trainings, training in processing durian derivative products in the form of durian gelato, durian ice cream, durian candy and frozen durian. Coffee derivative products include dried coffee beans, ground coffee packaging, coffee perfume, and key chains made from coffee waste. Business management training, including digital business records and a coffee drying house, and marketing outside the region are expected to improve the quality and quantity of durian and coffee for target partners, positively impacting the environment and strengthening the economy of the Brongkol Village community, transforming it into an agrotourism village.

Abstract

Perubahan Status UNNES dari PTN BLU ke PTN BH melalui Peraturan Pemerintah Nomor 36 Tahun 2022 menjadikan UNNES memiliki kemandirian baik non akademik dan akademik. Salah satu kemandirian non akademik adalah tata kelola organisasi dimana diatur lalui peraturan rektor. PTN BH UNNES telah menetapkan tata kelola organisasi melalui Peraturan Rektor nomor 11 Tahun 2023. Perubahan tata kelola harus diikuti perubahan sistem informasi sebagai sistem pendukung untuk memudahkan jalannya organisasi. Selain perubahan sistem informasi harus bersifat simpel, praktis, dan tidak banyak. Untuk itu perlu adanya intregrasi sistem informasi yang saling terkait. salah satunya adalah intregrasi MyUNNES Keuangan konten Perencanaan, Aset, dan MyUNNES-eProc. Penelitian ini telah menghasilkan intergrasi sebagai berikut; 1. MyUNNES-Keuangan konten Perencanaan dan Aset: Intergrasi yang telah dilakukan adalah tampilnya akun belanja modal dan beserta besarannya yang ada di konten perencanaan di konten RKAMU aset. Operator RKAMU tinggal melakukan detail belanja modal yang akan dilakukan. 2. MyUNNES-Keuangan konten Aset dan MyUNNES-eProc: RKAMU hasil intregrasi akan tampil di MyUNNES-Proc dengan detail kode barang, nama barang, spesifikasi barang, jumlah barang, unit pengusul, dan anggaran. Berdasarkan hasil uji kepada pengguna yaitu operator RKAMU, merasa puas terhadap hasil intregrasi. Sistem intergrasi ini perlu dilanjutkan untuk diintergrasikan ke sistem keuangan dan akuntansi.
