Abstract

Rawa Pening is a natural lake located in Semarang Regency that is facing issues with declining fish stock. Fish restocking activities in Rawa Pening are one of the solutions to maintain fish stock, fishermen's livelihoods, and food security. Fish restocking activities in Rawa Pening were carried out in July 2025 by the Undip community service team, involving the release of nilem and tawes fish, which are classified as local (non-invasive) species. An evaluation of local residents' perceptions of the fish restocking activities was conducted through interviews with 30 local residents who work as fishermen and fish processors. The evaluation results indicate that the fish restocking activity in Rawa Pening has received a positive response from the community service activity partners, with 100% of respondents agreeing with the restocking activity, primarily citing increased fishermen's income and maintaining fish populations in Rawa Pening as the main reasons. However, local residents' understanding and knowledge regarding the technical aspects of the restocking activity still need to be improved.

Abstract

Kritik dan komentar yang disampaikan masyarakat Indonesia terkait kebijakan pemerintah mengenai pembelajaran tatap muka di masa pandemi Covid-19 menuai pro dan kontra. Tidak sedikit orang tua yang khawatir dengan kebijakan ini dikarenakan para orang tua masih takut akan penyebaran klaster baru Covid-19 di Indonesia yang semakin berkembang, di sisi lain banyak juga orang yang beropini hal ini baik diterapkan mengingat pembelajaran secara daring dinilai kurang efektif karena banyak siswa yang sulit menerima materi yang disampaikan guru secara daring serta banyaknya siswa yang belum memiliki perangkat yang memadai. Banyaknya opini yang dituliskan di Twitter membutuhkan pengklasifikasian sesuai sentimen yang dimiliki agar mudah untuk mendapatkan kecenderungan opini tersebut apakah cenderung beropini netral, positif maupun negatif. Analisis sentimen dalam penelitian ini dilakukan dengan menggunakan metode Naïve Bayes dan seleksi ciri Chi Square dalam melakukan klasifikasi. Hasil analisis yang dari metode Naïve Bayes dengan seleksi ciri chi Square memiliki akurasi 93% dan tanpa seleksi ciri Chi Square memiliki akurasi 92%, sehingga dapat disimpulkan Metode Naïve Bayes dengan seleksi ciri Chi Square memiliki tingkat akurasi yang lebih baik dibanding tanpa menggunakan seleksi ciri Chi Square.

Abstract

Lembaga Amil Zakat (LAZ) memanfaatkan strategi Sistem Informasi/Teknologi Informasi (SI/TI) untuk meningkatkan daya saing. Seni Perang Sun Tzu telah banyak digunakan dalam penelitian untuk menyusun strategi bisnis dan strategi penjualan. Sayangnya, belum ada penelitian dengan menggunakan Seni Perang Sun Tzu untuk perencanaan strategis Sistem Informasi (SI). Kontribusi penelitian adalah penyusunan analisis SWOT berbasis lima faktor Seni Perang Sun Tzu sehingga dapat menjadi dasar untuk penelitian selanjutnya. Tujuan dari penelitian ini adalah untuk mengidentifikasikan kondisi lingkungan internal bisnis dan eksternal bisnis sehingga memberikan rekomendasi strategi kunci kepada LAZ dalam domain strategi bisnis, strategi SI/TI, dan strategi infrastruktur SI/TI berdasarkan analisis SWOT berbasis lima faktor Seni Perang Sun Tzu yang disusun berdasarkan metode Anita Cassidy. Beberapa strategi kunci yang dihasilkan dari peneitian ini adalah promosi dan edukasi zakat melalui media sosial dan media daring lainnya; menyediakan teknologi untuk memudahkan masyarakat membayar zakat dengan membuat aplikasi seperti Mobile Zakat, Customer Relationship System (CRS); dan mengembangkan kemampuan dalam memanfaatkan teknologi 5G dan teknologi baru.   Abstract Amil Zakat Institution (LAZ) uses Information System/Information Technology (IS/TI) strategy to improve competitiveness. Sun Tzu's Art of War has been widely used in research to develop business strategies and sales strategies. Unfortunately, there has been no research using Sun Tzu's Art of War for Information System (IS) strategic planning. The contribution of the research is the preparation of a SWOT analysis based on the five factors of Sun Tzu's Art of War so that it can be the basis for future research. This research aims to identify the condition of the internal business and external business environment to provide key strategy recommendations to LAZ in the domains of business strategy, SI/TI strategy, and SI/TI infrastructure strategy based on SWOT analysis based on five factors Sun Tzu's Art of War compiled based on the Anita Cassidy method. Some of the key strategies obtained from this research are the promotion and education of zakat through social media and other online media; providing technology to make it easier for people to pay zakat by creating applications like Mobile Zakat application, Customer Relationship System (CRS); and developing capabilities in utilizing 5G technology and new technologies.

Abstract

Since Satoshi Nakamoto first proposed the idea of bitcoin in 2009, the cryptocurrency and prediction methods for it have grown and changed exceptionally quickly. The Patterned Dataset Model was a valuable tool in earlier studies to explain how changes in the price of Bitcoin affect the movements of other cryptocurrencies in a digital trading market. Three different kinds of datasets are generated by this model: patterned datasets under full conditions, patterned datasets under dropping prices (Crash), and patterned datasets under rising prices (Moon). The K-means approach was then used to cluster these three datasets. Specifically, each dataset was split into two clusters, and the clustering score was determined by utilizing eight unique clustering metrics. Consequently, the best clustering score was found in the patterned dataset in the crash situation. Additionally, from 2022 to 2024, the raw data from this crash-condition-patterned dataset is used to determine the possibility of reaching maximum profit and return on investment (ROI) daily and monthly. According to the calculation results, the range computed over the course of a whole month (30 to 31 days) is significantly larger than the daily range (24 hours multiplied by one month), which represents the most significant profit and ROI attained before the emergence of the first diamond crash level. This research also covers the application of a deep learning model to forecast patterned datasets for crash scenarios that may occur many days in advance. The ConvLSTM2D Model performs better in predicting pattern dataset values for the subsequent crash scenario, according to the hyperparameter comparison between the Gated Recurrent Unit (GRU) Model and the 2D Convolutional Long Short-Term Memory Model.
