Kajian KAJIAN PSIKOANALISIS PADA NOVEL THANK YOU SALMA KARYA ERISCA FEBRIANI: Kajian Psikoanalisis pada Novel Thank You Salama
No full textPenelitian ini bertujuan untuk mendeskripsikan struktur kepribadian tokoh Salma dalam novel “Thank You Salma” karya Erisca Febriani menggunakan Teori Psikoanalisis Sigmund Freud yang terbagi atas id, ego, dan superego. Metode deskriptif kualitatif relevan dalam penelitian ini, dengan wujud data berupa kutipan teks yang bersumber dari novel “Thank You Salma” karya Erisca Febriani. Kemudian dianalisis dengan teknik: mengkategorisasikan bagian-bagian teks yang dikutip ke dalam struktur kepriadian tokoh Salma dalam tiga kategori yakni, id, ego, den superego; selanjutnya menginterpretasi dan menguraikan dalam bentuk deskripsi, kemudian memberi penyimpulan. Hasil penelitian menunjukkan bahwa, struktur kepribadian tokoh Salma dipengaruhi oleh 11 id, sembilan ego, dan tujuh superego. Id dalam diri Salma muncul karena dorongan atas sikapnya yang egois, perbedaan pendapat dengan Nathan, dan selalu mengekang apa yang Nathan lakukan. Ego dalam diri Salma bertugas meredakan kecemasan-kecemasan yang dirasakan mengenai karir masa depannya, kisah percintaanya dengan Nathan, dan trauma peleceham yang ia alami. Superego muncul sebagai bentuk hati nurani untuk mengendalikan sikap dan tingkah laku Salma yang egois dan tidak terkontrol.

Analyzing Students’ Cognitive Processes on Trigonometric Functions beyond 90 Degrees through the DAPIC Framework
No full textUnderstanding trigonometric functions at angles beyond 90 degrees presents unique cognitive challenges for students, requiring the integration of conceptual, procedural, and representational knowledge. However, research exploring how students cognitively process such problems, especially within a structured framework, remains limited. This study aims to analyze students’ cognitive processes in solving trigonometric problems involving beyond-90-degree angles through the DAPIC framework (Define, Assess, Plan, Implement, Communicate), offering a novel application of DAPIC to this underexplored context. A qualitative case study approach was employed, involving six 11th-grade students from a public high school with varying cognitive levels. Data were collected through diagnostic tasks, think-aloud protocols, and semi-structured interviews, and were analyzed by mapping students’ thinking patterns, defined as the recurring sequences of cognitive moves and representation use observed across DAPIC stages. The results reveal that high-performing students demonstrated flexible shifts between symbolic, graphical, and unit circle representations and were capable of self-regulating their errors reflectively. In contrast, students with moderate and low performance encountered difficulties in identifying the quadrant of angles and understanding the periodic nature of trigonometric functions, particularly during the Assess and Plan stages. Adaptive strategies, such as visual re-checking or intuitive quadrant reasoning, emerged spontaneously but were not always effective. These findings suggest that DAPIC serves as a systematic tool for capturing the dynamics of students’ thinking processes and offers valuable insights for developing deeper instructional strategies in trigonometry, especially for topics involving beyond-90-degree angles
Investment Risk Analysis Using Value at Risk With Monte Carlo Simulation: Investment risk analysis
No full textThis study aims to evaluate and compare the investment risk levels of three primary financial instruments in Indonesia: the Indonesia Composite Index (IHSG), Bank Central Asia (BCA) with code BBCA stock, and gold. Using the Value at Risk (VaR) approach based on Monte Carlo simulation, the research integrates these assets into a unified risk assessment model, providing a more comprehensive perspective than prior studies that typically examine individual assets or use historical estimation methods. Monthly historical price data from April 2024 to March 2025 were obtained from the Indonesia Stock Exchange and the Central Bureau of Statistics. The analysis involved calculating asset returns, means, and standard deviations, followed by 10,000 Monte Carlo simulation iterations to generate potential future price paths and estimate losses under market uncertainty. The results, at a 95% confidence level, show that IHSG carries the highest investment risk, with a VaR of IDR 9,331.16, followed closely by BBCA stock at IDR 9,210.31. Gold exhibited the lowest risk level, with a VaR of IDR 6,896.86, confirming its role as a more stable and less volatile investment compared to equity-based assets. These findings highlight the reliability of gold as a defensive asset during turbulent market conditions. The application of Monte Carlo simulation effectively captures the non-normal distribution of returns and accommodates complex market behaviors, making it a robust tool for financial risk modeling. This research offers meaningful insights for investors, analysts, and academics in optimizing portfolio strategies and improving risk management decisions

The results obtained from the question are directly proportional to the results of the causes of misconceptions using questionnaire instruments, based on questionnaire data, the percentage of causes of misconceptions is 61.11% from students, 15.56% from teachers, 40.56% from the internet, 45% from friends, and 25% from books
Mapping of Flood-Prone Areas in Malaka Regency Based on WebGIS Using the Simple Additive Weighting (SAW) Method
No full textMalaka Regency in East Nusa Tenggara Province is a flood-prone area, mainly due to high rainfall and the overflow of the Benenain River, the largest watershed in the province. This study aims to map flood-prone areas using the Simple Additive Weighting (SAW) method integrated into a WebGIS-based decision support system. The variables considered include rainfall, land use, slope, topography, and river flow. The analysis resulted in three flood vulnerability classifications: low (Laenmanen, Iokafeu, Botinleobele, Sasitamean), moderate (Kobalima, Kobalima Timur, Malaka Timur, Rinhat), and high (Malaka Tengah, Malaka Barat, Weliman, Wewiku). This system is expected to assist local governments in making timely and accurate decisions for flood disaster management and mitigatio
