Published: March 2024

Los modelos de combustibles estandarizados son una herramienta útil para predecir el comportamiento del fuego y plantear estrategias de supresión de incendios forestales. El objetivo del presente trabajo fue comparar las simulaciones del comportamiento del fuego con el resultado de una quema prescrita en un bosque de encino-pino en Guerrero, México. Se colectaron muestras de hojarasca (Ho) y mantillo (Ma) en 0.09 m2 al final de las líneas de intersección planar para el muestreo de combustibles leñosos. Las simulaciones en el sistema FUEGO se basaron en: a) cargas de combustible de campo y b) cargas teóricas de los modelos 8 y 9. Durante el desarrollo de la quema se monitoreo la temperatura (T), humedad relativa (HR), velocidad del viento (VV), altura de llama (ALL) y velocidad de propagación del fuego (VP). La carga de combustible 11 t ha-1, propicio una VP = 1.07 m min-1 y ALL = 0.65 m para quemas en contra de la pendiente. Las simulaciones con un cuadrado medio del error (CME) de 0.11, evidenciaron valores aceptables de ALL (0.54 y 0.64 m) a excepción del modelo ALL-M8 con 0.24 m (p < 0.05). La VP-real no presento diferencias estadísticas con las simulaciones para valores de 0.40 y 1.78 m con un CME = 0.54 y 1.56, los modelos VP-9 y VP-M9 propiciaron valores de simulación altos, respecto a la VP-M8 (p < 0.05). El comportamiento del fuego respondió a los cambios de HR, VV y distribución espacial de los combustibles en el terreno.

Background: Parkinson's disease (PD) is a critical neurodegenerative disorder affecting the central nervous system and often causing impaired movement and cognitive function in patients. In addition, its diagnosis in the early stages requires a complex and time-consuming process because all existing tests such as electroencephalography or blood examinations lack effectiveness and accuracy. Several studies explored PD prediction using sound, with a specific focus on the development of classification models to enhance accuracy. The majority of these neglected crucial aspects including feature extraction and proper parameter tuning, leading to low accuracy.
Objective: This study aims to optimize performance of voice-based PD prediction through feature extraction, with the goal of reducing data dimensions and improving model computational efficiency. Additionally, appropriate parameters will be selected for enhancement of the ability of the model to identify both PD cases and healthy individuals.
Methods: The proposed new model applied an OpenML dataset comprising voice recordings from 31 individuals, namely 23 PD patients and 8 healthy participants. The experimental process included the initial use of the SVM algorithm, followed by implementing PCA for feature extraction to enhance machine learning accuracy. Subsequently, data balancing with SMOTE was conducted, and GridSearchCV was used to identify the best parameter combination based on the predicted model characteristics.
Result: Evaluation of the proposed model showed an impressive accuracy of 97.44%, sensitivity of 100%, and specificity of 85.71%. This excellent result was achieved with a limited dataset and a 10-fold cross-validation tuning, rendering the model sensitive to the training data.
Conclusion: This study successfully enhanced the prediction model accuracy through the SVM+PCA+GridSearchCV+CV method. However, future investigations should consider an appropriate number of folds for a small dataset, explore alternative cross-validation methods, and expand the dataset to enhance model generalizability.

A Practical Approach to Enhance Data Quality Management in Government: Case Study of Indonesian Customs and Excise Office
Authors: Nugraha Tito Febrian , Wibowo Wahyu Setiawan , Genia Venera , Fadhil Ahmad , Ruldeviyani Yova 
Published: March 2024

Background: The exponential data growth emphasises the importance of efficient information flow in organisations, especially in the financial sector. Data quality significantly influences decision-making, necessitating reliable Data Quality Management (DQM) frameworks. Previous studies propose DQM to maintain data quality through regulation, technology, measurement, evaluation, and improvement. Researchers highlight high-quality data benefits in private organisations but note the lack of improvement in data utilisation in public organisations. In Indonesia, data accuracy and quality are crucial for financial policies, with frequent reports of data inaccuracies in the Directorate General of Customs and Excise (DJBC), demanding standardised DQM practices. However, However, prior studies have yet to provide comprehensive and practical solutions to improve DQM practices. This study therefore aims to measure the DQM maturity, provide recommendations based on best practices, and formulate a practical strategy for improvements along with indicators tailored to the organisation, a topic that previous research has not explored.
Methods: This study falls under a mixed method approach (a quantitative study followed by a qualitative study) and employs a three-stage methodology. The authors conduct maturity assessment using Loshin model through an assisted enumeration from 5 key stakeholders followed by recommendations based on the Data Management Body of Knowledge (DMBOK) and strategy formulation from internal documents and interview.
Results: The data analysis yielded a DQM maturity score of 3.10, indicating a "defined to managed" level of maturity. Among eight components, only one receives a Managed level, two components are in the Defined level and the rest belongs to a Repeatable level. This study also proposes three strategies to bolster DQM by targeting 49 weak points, which will be progressively and sequentially implemented over a three-year period, using twelve possible solutions.
Conclusion: The study highlights the importance of efficient data flow, particularly in the financial sector, and suggests DQM for maintaining data quality. DJBC's import DQM level is assessed using Loshin's measurements, revealing areas for improvement through key DMBOK activities. Recommendations include data governance, strategic planning, and sequential DQM implementation. The study concludes by formulating a practical approach to be applied in a three-year span with ten indicators to measure success.

Arrangements for Granting Visas and Immigration Stay Permits for Digital Nomads in Indonesia in View of Legal Certainty
Authors: Imam Lalu Syamsul , Wibowo Gatot Dwi Hendro , Cahyowati Cahyowati 
Published: March 2024

In the era of globalization, Indonesia stands to gain substantial benefits by swiftly implementing regulations governing visas and residence permits for digital nomads, ensuring legal certainty and unlocking significant economic potential. This research employs a normative legal approach to analyze the concept of specialized visa and residence permit arrangements for digital nomads in Indonesia, focusing on legal certainty and the classification of their activities as work. Current findings indicate a lack of specific rules for digital nomads, leading to the use of conventional visas that may not align with their online work. As digital nomads inherently engage in freelance work, compliance with labor and taxation regulations becomes imperative. To establish lawful and protected status, the government should introduce new arrangements, such as digital nomad visas with stipulated requirements like financial capability and tax payments, fostering legal certainty for all stakeholders.
Highlights:

Legal Void: The absence of specific rules for digital nomads in Indonesia leaves them reliant on conventional visas, creating a legal vacuum for their online work activities.

Freelance Work Classification: Given that digital nomads essentially function as freelance workers, the research emphasizes the necessity of appropriately categorizing their activities within the framework of labor and taxation regulations.

Policy Recommendations: The study advocates for the prompt establishment of specialized digital nomad visas and residence permits in Indonesia, incorporating financial criteria and tax obligations to ensure legal certainty and unlock economic potential.
