Classification Of Outstanding Students Using Support Vector Machine (SVM) Based on Data Mining
This research aims to classify outstanding students at the Pagar Alam Institute of Technology using the Support Vector Machine (SVM) algorithm based on data mining. Early identification of outstanding students is crucial for supporting potential development and institutional decision-making. Historical data from 245 students from the 2016 to 2018 cohorts were utilized, encompassing course grades and Cumulative Grade Point Average (CGPA). The research process included data preprocessing such as normalization and splitting the data into 80% training data and 20% testing data. The SVM model was implemented with a Radial Basis Function (RBF) kernel and parameters C=1.0 and gamma=0.1. Evaluation results show that the model achieved an overall accuracy of 89.80% on the testing data. The model's performance was further validated through a confusion matrix (9 True Positives, 1 False Negative) and a classification report indicating good precision and recall for both classes. Furthermore, an Area Under the Curve (AUC) value of 0.93 signifies the model's excellent discriminative ability. This study contributes by providing an effective classification tool for identifying outstanding students, which can serve as a basis for the institution to design more targeted development and recognition programs
Sentiment Analysis to Evaluate Public Service Perception among Surakarta City Residents Using the BiLSTM Model
The growing use of social media as a platform for public communication has opened new opportunities for understanding public opinion regarding government policies, including public services. One of the cities actively discussed on social media is Surakarta, where citizens openly express both appreciation and criticism of local government performance. This study aims to analyze public sentiment toward public services in Surakarta by employing a deep learning-based sentiment analysis approach, specifically using the Bidirectional Long Short-Term Memory (BiLSTM) model. Data were collected from Twitter/X using a web crawling technique with the keywords “pemerintah solo” (Solo government), “kota Surakarta” (Surakarta city), and “kota solo” (Solo city), resulting in 2,168 tweets. The analysis process involved several stages, including preprocessing, sentiment labeling using a lexicon-based method, feature representation with Word2Vec, and classification using five models: SVM, Random Forest, CNN, LSTM, and BiLSTM. The evaluation results show that BiLSTM achieved the best performance with an accuracy of 90.21%, precision of 91.05%, recall of 89.84%, and F1-score of 90.43%. The conclusion of this study is that BiLSTM can effectively classify public sentiment toward public services, especially in the context of informal social media texts. The implication of this research indicates that sentiment analysis can serve as a decision-support tool for designing more responsive and data-driven public policies and provide strategic insights for local governments in improving the quality of public services
Peranan Camat Dalam Meningkatkan Kinerja Aparatur Sipil Negara di Kecamatan Hinai Kabupaten Langkat
This study will analyze the sub-district head's role in improving the State Civil Apparatus (ASN) performance in Hinai District, Lalat Regency, and identify the inhibiting factors. Using a descriptive qualitative approach through observation, interviews, and documentation. The respondents interviewed included the Sub-district Head, the Sub-district Secretary, the head of the section, and the local community to get a comprehensive picture of the role of the Sub-district Head in improving the performance of ASN. This research shows that sub-districts have a strategic role as policymakers, leaders, motivators, supervisors, and ASN coaches. The sub-district head also encourages the improvement of ASN competencies through training, optimization of the use of technology, and strengthening accountability and transparency of public services. However, the effectiveness of the role of the sub-district head faces internal obstacles, such as low technological competence of ASN, resistance to change, and limited human resources. External barriers include limited technological infrastructure, minimal budgets, and increasing societal demands. To overcome this challenge, the sub-district needs to develop strategies such as continuous training, socialization of the importance of innovation, optimization of task division, and cooperation with local governments and external parties to improve the performance of civil servants and the quality of public services.Penelitian ini bertujuan menganalisis peran camat dalam meningkatkan kinerja Aparatur Sipil Negara (ASN) di Kecamatan Hinai, Kabupaten Langkat, serta mengidentifikasi faktor penghambatnya.

E EFEKTIVITAS KONSENTRASI EKSTRAK BIJI MIMBA DALAM MENGENDALIKAN HAMA PADA TANAMAN DAUN BAWANG (Allium fistulosum.)
This study aimed to determine the effectiveness of neem seed extract (Azadirachta indica) as a botanical pesticide in controlling pests on scallion (daun bawang) plants and to identify the most effective concentration. The experiment involved three extract concentrations (50 ml, 100 ml, and 150 ml per liter of water) and three application times (W1, W2, W3), with observed variables including damage intensity and the number of affected leaves. Analysis of variance showed that on day 7, the extract concentration significantly influenced pest attacks, with the 100 ml concentration (M2) being the most effective. However, on days 14 and 21, neither dosage nor application time individually showed significant effects, although the interaction between them (MxW) was statistically significant. These results suggest that the effectiveness of neem-based botanical pesticides is situational and depends on the interaction between dosage and timing. This finding can serve as a reference for developing more precise and eco-friendly pest control strategies
Public Transport Arrangement: A Study of Policy Implementation in Bandung City
This study aims to analyze the implementation of Public Transportation Regulations in Bandung City, Indonesia. The issues focused on are the policy content and the context of its implementation. This study applies Grindle's policy implementation framework to critically examine policy implementation, exploring how political interests, administrative capacity, and institutional dynamics shape policy outcomes, dimensions often overlooked in transport policy research. This study fills a gap in urban transportation research that largely focuses on technical and infrastructure solutions. This study uses a descriptive qualitative approach using in-depth interviews, direct observation, and document analysis involving government officials, transportation operators, drivers, and users in Bandung City. The results indicate that policy implementation has not been successful for several reasons: the policy content does not accommodate the interests of the community and operators; the community is not interested in the long-term benefits of using public transportation; the anticipated changes in the policy are too broad; coordination problems between implementing agencies; and insufficient resource allocation. Policy implementation is also hampered by various contexts, namely: the existence of strong patron-client relationships between actors in channeling their economic interests; mechanisms for community engagement that have not been institutionalized; and low bureaucratic responsiveness
Making Collaboration Work: A Systematic Multidimensional Review of Collaborative Governance
Collaborative governance (CG) has become a crucial approach for addressing complex public issues that single actors cannot solve. Despite its growing relevance, the understanding of CG remains fragmented. This study aims to synthesize the existing CG literature to provide a more cohesive understanding and identify a future research agenda. Using a systematic, multidimensional literature review, 53 academic documents were qualitatively analyzed. The findings reveal key antecedent conditions for successful collaboration, including a sense of community, a favorable historical context, and a level playing field.
Furthermore, the study identifies eleven critical factors that contribute to effective collaborative networks. The synthesis highlights the strengths of CG literature in institutional and multilevel analysis but also points to significant gaps in integrative dimensions and developmental dynamics. This study contributes a systematic, multidimensional framework that advances collaborative governance theory by integrating institutional, processual, and contextual dimensions and addressing the research gap in comprehensive CG synthesis. The findings reveal that future research must address these gaps to advance both theoretical knowledge and practical application, particularly in diverse contexts like public administration in Indonesia
