Abstract

Konsep perencanaan strategis menjadi terkenal pada 1980-an di bawah bendera Manajemen Publik Baru; Sejak saat itu, beberapa komponen perencanaan strategis sektor swasta telah diimplementasikan dan diinterpretasikan di sektor publik. Sementara banyak dari konsep-konsep ini bukanlah hal baru, penerapannya pada sektor publik adalah hal yang baru. Kebangkitan dan penerimaan umum dari perencanaan strategis sektor publik juga bertepatan dengan revolusi digital yang dimulai pada akhir 1980-an, menawarkan janji yang sangat besar, tetapi juga jumlah potensi jebakan yang sama. Hasil penelitian adalah Strategi Bisnis berpengaruh terhadap Perencanaan Organisasi dan Perkembangan Teknologi Mempengaruhi Perencanaan Organisasi.

Abstract

The Pelton turbine is a type of impulse turbine that utilizes a high-pressure water jet through a nozzle to rotate the turbine buckets. One factor influencing turbine performance is the number of valve openings, as the opening size determines the water flow rate directed to the turbine. This study aims to analyze the effect of the number of valve openings on the performance of a Pelton turbine prototype. The research method employed is an experimental approach by varying the valve openings, resulting in different water flow rates, followed by measurements of torque, water power, turbine power, and efficiency. The tests were conducted under a constant load of 1 kg with 12 buckets. The results show that the maximum torque obtained was 0.2695 Nm. The highest water power of 15.41 W occurred at a flow rate of 30 LPM, while the lowest water power of 10.03 W was recorded at the smallest flow rate. The highest turbine power was 9.45 W, and the maximum efficiency was achieved at a flow rate of 26 LPM with valve openings producing an effective nozzle diameter of 9–11 mm, reaching 90.97–91.38%. The lowest efficiency was observed at a valve opening equivalent to a 9 mm nozzle diameter, at 22.15%. These findings indicate that the number of valve openings has a significant effect on Pelton turbine performance, particularly in terms of efficiency and output power

Abstract

Materials are crucial raw materials in the industrial world, both in terms of capacity, for both large and small industries. Over time, and with increasing competition, inspections are inextricably linked. Inspections require tools to simplify and increase measurement accuracy during operator operations. Automated systems utilizing pneumatics for inspection are increasingly used in the industrial world because they utilize readily available air. Tool design requires analysis, planning, and calculations of the required main components. The results of the planning process determine the pneumatic size based on the maximum load force and air pressure used, and can then determine the compressor power. In addition, pneumatic systems can be combined with conveyor systems, where the main conveyor design includes motor power, belt type, and roller shaft size, along with calculations for torque, speed, torsional moment, and bending moment.

Abstract

Advances in digital technology have made social media the primary platform for the public to voice their opinions on government policies, including the Free Nutritious Meals (MBG) program. This study aims to compare the performance of the Support Vector Machine (SVM) and Random Forest algorithms in conducting sentiment analysis of public opinion on the X platform regarding this policy, in order to provide an objective overview for policymakers. A total of 2,164 tweets were collected via crawling using Tweet Harvest from May to August 2025. The methodological steps included preprocessing, BERT-based automatic labeling, Eliminate the neutral class to focus the analysis on binary classification (positive and negative), TF-IDF feature extraction, and the application of SMOTE to address class imbalance in the dataset. Model optimization was performed using Grid Search with a 5-Fold Cross Validation testing scheme and an 80:20 data split. The results of the study indicate that the majority of public responses to the MBG program were positive. Based on the final evaluation, the SVM with a linear kernel proved superior with an accuracy of 78.24% and a macro average F1-score of 0.76, outperforming the Random Forest (300 estimators), which achieved an accuracy of 75.00% and an F1-score of 0.73. The application of SMOTE has proven to be crucial in improving the negative class recall, enabling the model to identify minority sentiments more accurately. This study concludes that SVMs demonstrate more stable and objective generalization capabilities in mapping public opinion following data balancing.
