The Role of the North Sumatra Provincial Bawaslu in the 2019 Election: Performance Analysis and Design of an Adaptive Supervision Model
Get PDFThis study aims to analyze the role of the North Sumatra Provincial Election Supervisory Agency (Bawaslu) in implementing the 2019 Election and formulate a more effective and contextual supervision model. This study uses a qualitative approach with a case study method. Data was collected through in-depth interviews, observations, and documentation from informants such as Bawaslu and KPU commissioners, academics, party administrators, and the public. The results of the study show that the role of Bawaslu has not been optimal due to various obstacles, including limited human resources, weak coordination between institutions, and a recruitment process that is not transparent and full of political interests. Election supervision tends to be administrative and formal, with no strict law enforcement measures. For this reason, the researcher offers a supervision model that integrates the role indicators, according to Biddle and Thomas, with the three types of Donnelly supervision and adds two important indicators: the quality and quantity of human resources. This model is expected to strengthen the professionalism and effectiveness of Bawaslu's supervision in overseeing democratic, honest, fair, and integrity elections and increase public trust in the region's election process

No full textThe limited availability of suitable land for oil palm cultivation encourages farmers to utilise tidal peatlands. However, tidal peatlands are considered less appropriate for oil palm plants. The utilisation of tidal peatlands for oil palm plantations hurts production, productivity, and income received by farmers if farmers do not apply standardised cultivation techniques. This study aims to analyse the application of independent oil palm cultivation techniques, the amount of income of independent oil palm farmers, and the efficiency level of independent oil palm production on tidal peatlands in Indragiri Hilir Regency. The sampling method used was the Accidental Sampling method with 40 samples. This study was conducted in two sub-districts in Indragiri Hilir Regency, namely Kempas District and Tempuling District, using GAP analysis of oil palm cultivation techniques, analysis of farm income and analysis of production efficiency with stochastic frontier. The results of the study indicate that the application of oil palm cultivation techniques on tidal peatlands has not followed the recommendations set by the Palm Oil Research Centre (PPKS) by the principles of Good Agricultural Practices (GAP). Of the 11 recommended cultivation techniques, only land clearing, weed control, planting patterns, and harvesting were applied 100 per cent. The average production of oil palm on tidal peatlands reached 31,181 kg/year, with a productivity of 10,055 kg/ha/year. The average production cost incurred by farmers was Rp9.530.672/ha/year. The total income of farmers reached Rp19.432.482/ha/year, while the average net income of farmers was Rp.9.901.809/ha/year. All farmers who farm oil palm on tidal peatlands have achieved technical efficiency, but are not yet allocatively and economically efficient.Kabupaten Indragiri Hilir merupakan salah satu daerah sentra produksi kelapa sawit, di mana Kabupaten Indragiri Hilir menjadi kabupaten dengan luas lahan basah dan lahan gambut terbesar di antara kabupaten/kota di Provinsi Riau.

A Implementation of West Manggarai Regent Regulation No. 58 of 2017 concerning Hotel and Restaurant Tax on Tour Ships
No full textThis study examines the implementation of hotel and restaurant tax policies on tourist ships in West Manggarai Regency. This policy aims to optimize the potential of Regional Original Revenue (PAD) from the tourism sector, especially accommodation and restaurant services provided by tourist ships. Hill and Hupe used a reference to policy implementation theory to analyze this problem. Data is collected through document studies sourced from written documents or archives, newspapers, and published and qualitatively analyzed statistical data. The study results concluded that although online tax reporting systems have been implemented to improve efficiency, the realization of tax revenues often does not reach the target. Factors that hinder these achievements include low taxpayer compliance, lack of socialization, limited human resources in supervision, and lack of coordination between stakeholders. This study recommends increasing socialization, technical training for business actors, and strengthening stakeholder coordination to improve policy effectiveness. In addition, strict sanctions are needed for business actors who do not comply, and incentives are provided for those who fulfill their obligations. These findings are expected to be useful for local governments in managing tourism tax potential more optimally

Enchancing Brain Tumor Disease Classification via SqueezeNet Architecture Integrated with Group Convolution
Get PDFBrain tumor classification using MRI images is a major challenge in medical image processing, particularly when facing imbalanced data between classes. This imbalance often leads to model bias toward the majority class and reduces sensitivity to the minority class—patients with tumors. This study aims to analyze the impact of applying Group Convolution techniques to the VGG19 and SqueezeNet architectures to enhance both computational efficiency and classification accuracy. A quantitative experimental approach was employed, implementing Convolutional Neural Networks (CNNs) using the PyTorch framework. The dataset includes two classes, “Yes” (with tumor) and “No” (without tumor), organized into Train, Validation, and Test folders. The models were evaluated by comparing the performance of standard architectures with modified versions integrating Group Convolution. Experimental results show that SqueezeNet with Group Convolution achieved up to 90% accuracy, outperforming the original model. Additionally, the model exhibited significantly improved sensitivity to the minority class, indicating better performance under imbalanced conditions. These findings suggest that Group Convolution enhances not only computational efficiency but also classification capability. Therefore, this technique is applicable in developing automated diagnostic systems. Future research is encouraged to combine Group Convolution with methods such as attention mechanisms to achieve more optimal and reliable classification results
