Abstract

The increasing global energy demand drives the development of efficient and sustainable renewable energy solutions. Floating Solar PV (FSPV) technology offers a viable solution by utilizing water surfaces such as reservoir ash ponds in coal-fired power plants without requiring additional land. This study aims to analyze the technical and economic aspects of an FSPV system with a capacity of 15.2 kWp using HelioScope and Homer Pro software, assuming Global Horizontal Irradiance (GHI) data from the National Solar Radiation Database. The analysis methods include annual energy production, Net Present Cost (NPC), Levelized Cost of Energy (LCOE), and other economic metrics such as Return on Investment (ROI), Internal Rate of Return (IRR), and Simple Payback Period for various grid electricity price escalation scenarios. The results show that a 5% annual increase in grid electricity prices reduces the simple payback period from 18.2 years to 13 years, with an ROI increase to 6.3% and an IRR of 7.1%. This study concludes that the FSPV system not only supports the transition to clean energy but also offers greater financial benefits under scenarios of rising grid electricity prices.

Abstract

Access to energy and electricity drives the economy, including industrial activities in isolated areas. Currently, the shrimp industry on Bawean (an isolated area) is facing the problem of many unserved power needs. Thus, this study aims to design hybrid renewable energy for the productive sector. There are two configurations, namely configuration 1 (PV SYSTEM, WIND TURBINE SYSTEM, GRID, BESS) and configuration 2 (PV SYSTEM, GRID, BESS), which find the potential for solar and wind radiation very suitable for renewable energy sources. Thus, based on the HOMER simulation, the best alternative solution is configuration 1 which utilizes PV SYSTEM (8.9 MW), 2 Wind Turbine System (1.6 MW), and 3 BESS, resulting in the lowest LCOE value of 0.137 $/kWh. The results of configuration 1 can meet the electricity needs of Bawean Island and shrimp ponds with the lowest LCOE value, so it can potentially increase productive sectors such as shrimp ponds.

Abstract

This study aims to develop an annotated corpus and a deep learning-based Named Entity Recognition (NER) model to identify legal entities in Indonesian corruption court rulings. The corpus was constructed from 450 Supreme Court documents related to the Anti-Corruption Laws (Laws No. 31/1999), collected via web scraping, with semi-automatic annotation (regex) and validation by legal experts. A total of 12,000 entities (Article, Laws, Sanctions) were tagged in IOB format, creating the first specialized dataset for Indonesian corruption laws. The NER model combines the IndoBERT (pre-trained language model) architecture with a CRF layer, fine-tuned to handle legal text complexities such as hierarchical article references (paragraphs, clauses) and amended laws citations (jo.). Evaluation using 10-fold cross-validation revealed that the model achieved an F1-score of 92.3%, outperforming standalone CRF (85.1%) and BiLSTM+CRF (88.7%), particularly in detecting ARTICLE entities (F1: 93.8%). Error analysis highlighted challenges in recognizing SANCTIONS entities (F1: 87.4%) due to sentence structure variability and conjunctions. The model’s implementation could accelerate judicial decision analysis, identify violation patterns, and support sanctions recommendation systems for laws enforcement. This research also provides legal entity annotation guidelines adaptable to other legal domains. Future work should expand to other laws (e.g., ITE Laws, Criminal Code) via transfer learning and integrate knowledge graphs to enhance entity relation detection.

Abstract

The Kawali Inscription, discovered in Ciamis Regency, West Java, is a significant historical artifact dating back to the 5th century AD. As one of the few surviving sources from the Sunda Kingdom, it offers valuable insights into the region's political, cultural, and historical context. This study aims to explore the historical and cultural values embedded in the inscription and examine how these can be effectively integrated into the Social Studies (IPS) curriculum for elementary and secondary education. Employing a qualitative approach with historical and content analysis methods, the research reveals that the Kawali Inscription is a rich resource for fostering students’ understanding of local history, strengthening cultural identity, and promoting critical thinking. The integration model includes the development of contextual learning materials, interactive teaching strategies, and project-based assessments aligned with curriculum objectives. This approach not only enriches historical learning but also supports character education through appreciation of Indonesia’s cultural heritage.

Abstract

Srivijaya was the largest maritime kingdom in Southeast Asia that reached its peak in the 7th to 13th centuries AD. Its strategic position on international trade routes made it a center of economic and cultural exchange connecting East Asia, South Asia, and the Middle East. One of the evidences of Srivijaya's trade and cultural acculturation traces can be found on the Musi River, which functioned as the main route for distributing trade goods. This study uses historical methods, including heuristics (collection of sources), source criticism, interpretation, and historiography, to analyze archaeological findings in the form of ceramics and ancient money found in the Musi River, Palembang. The results of the study show that the ceramics found in the Musi River, Palembang come from various dynasties in China, such as the Tang Dynasty (618–907 AD), Song (960–1279 AD), and Yuan (1271–1368 AD), indicating close trade relations between Srivijaya and China. In addition, the discovery of ancient currencies, including gold, silver, and copper coins from local and Chinese sources, reveals that Srivijaya already had a currency-based economic system in its trade transactions. Through source criticism and analysis, it was found that the flow of trade on the Musi River not only had an impact on the economic development of Srivijaya, but also influenced the social and cultural aspects of its people, such as in art, belief systems, and daily life patterns. This study confirms that Srivijaya was not only a regional trade center, but also an important node in the global trade network that accelerated the process of cultural acculturation. Using historical methods, this study provides deeper insight into the dynamics of Srivijaya trade and culture, and enriches understanding of the role of the Palembang Musi River in the maritime history of the archipelago.

Abstract

The Damarwulan–Minakjinggo story is part of the traditional Langendriyan art heritage and developed in Banyuwangi. This story depicts the conflict between Damarwulan and Minakjinggo. Historically, this story was used by the Mataram Sultanate to build political legitimacy by depicting Minakjinggo as rebels, while the Dutch adapted the narrative to stigmatize the Blambangan community. This study aims to examine the origins, transformations, and impacts of this performance in a political and cultural context, using historical methods with a deconstruction approach from Derrida. The discussion highlights how this story was transformed into a tool for political legitimacy, as well as how the Banyuwangi community reconstructed the story to strengthen local identity. The implications of this study indicate that the transformation of the Damarwulan-Minakjinggo story strengthens local identity and makes art a means of resistance to dominant narratives. In conclusion, this story reflects how art and historical narratives can adapt to social and political changes, and enrich understanding of cultural identity that is relevant to modern values.

Abstract

This study aimed to develop hypnoteaching-based learning media to enhance fifth-grade students' learning outcomes in Natural and Social Sciences (IPAS – a subject that integrates natural and social science content in the Indonesian elementary curriculum) using the ADDIE model. Conducted in a public elementary school in Central Java, the study employed expert validation, observation, student response questionnaires, and learning outcome tests. Data were analyzed using descriptive statistics and paired-sample t-tests. Results showed excellent validity (average expert rating = 4.7) and a significant improvement in scores from the pre-test (60.00) to the post-test (70.26), with an N-Gain of 0.26, categorised as low based on Hake's criteria. The media received a positive response from students (average satisfaction score = 4.2). Despite the low N-Gain, the hypnoteaching-based media proved to be a practical and engaging tool. Future integration with broader educational technologies is recommended.
