Abstract

This study aims to analyze the power struggle in George Orwell's novel Animal Farm. The author describes the novel Animal Farm using the historical hermeneutic approach of Wilhelm Dilthey and Roland Barthes' semiotic interpretive method. Research data comes from conflicts between animals and humans and between animals on farms. The data analyzed was taken from reading the novel Animal Farm repeatedly and understanding every element in the story. The author then divides the power struggle based on the tyranny that carries out slavery on the farms. Among them is the propaganda by pigs to rebel against all animals against humans. Animal propaganda is not to imitate and torment humans—and pig animal propaganda is to control the farm personally. The results showed that the power struggle in the form of propaganda and violence was influenced by the difference in ideology to exercise power on the farm. And the conclusion of this study is that George Orwell, through his work, is conducting propaganda and criticizing the ideology of power.

Abstract

This study presents a comprehensive, simulation-based validation of a Luenberger Observer (LO) specifically designed for fault detection in storage tank systems. It commences with the development of a nonlinear storage tank model, which is subsequently linearized to streamline the observer design process. The LO estimates critical system states and produces residual signals that enable reliable fault detection. The observer gain is meticulously chosen using pole placement techniques to ensure rapid convergence of estimates and overall stability. To evaluate the effectiveness of this approach, three distinct fault scenarios—ramp, square pulse, and inverted ramp signals—are introduced to simulate various types of abnormal conditions that could occur in real-world operations. Simulation results demonstrate that the LO accurately estimates the liquid level states with a mean absolute error of approximately 0.02 meters, equivalent to about 2.6%. Furthermore, the observer detects faults with an average delay between 5 and 9 seconds following fault injection, indicating its prompt response capability. Notably, even with sensor noise levels reaching 6%, the observer maintains stable tracking performance, demonstrating strong robustness against disturbances. Across all tested scenarios, the residual signals show rapid increases during fault conditions and swiftly return near zero once the system reverts to normal operation, with no false alarms observed. Collectively, these results suggest that the Luenberger Observer provides an accurate, rapid, and disturbance-tolerant method for fault detection in storage tank systems. Such an approach offers a practical alternative to data-driven fault detection methodologies, as it relies less on extensive training datasets and can be more readily implemented for real-time industrial monitoring applications.

Abstract

Production forecasting in the agricultural sector is an important component in the planning and decision-making process, especially for commodities with high levels of demand such as cayenne pepper. This study aims to predict the amount of cayenne pepper production in Riau Province by applying the Holt-Winters Multiplicative method. The selection of this method is based on its ability to process time series data that has seasonal patterns and trends that change proportionally to the data level. The data used in this study is secondary data sourced from the Riau Province Food, Food Crops, and Horticulture Office for the period from 2022 to 2024. The analysis stage includes data exploration, determination of the initial smoothing value for levels, trends, and seasonality, adjustment of smoothing parameters (α, β, γ), and evaluation of model performance using MAPE, MAD, and MSE error measures. Based on the results of the analysis, it shows that the Holt-Winters Multiplicative model produces a MAPE value of 11%, which indicates that the model has a good level of accuracy. Therefore, this method can be used as a supporting tool in planning the production and distribution of cayenne pepper in Riau Province.

Abstract

Produksi rumput laut Kabupaten Takalar merupakan salah satu kontributor utama dalam rantai pasok industri rumput laut nasional. Penelitian ini bertujuan untuk menganalisis tren produksi rumput laut Takalar periode 2020–2024 serta memproyeksikan perkembangan produksi hingga tahun 2029 untuk tiga komoditas utama, yaitu Kappaphycus alvarezii (Cottonii), Eucheuma spinosum, dan Gracilaria. Metode yang digunakan meliputi analisis deret waktu, regresi linear untuk memodelkan tren produksi, serta perhitungan proyeksi lima tahun berbasis persamaan regresi tiap komoditas. Selain itu, analisis dilakukan terhadap struktur produksi, kontribusi antar komoditas, dan dinamika perubahan produksi tahunan. Hasil penelitian menunjukkan bahwa produksi total rumput laut Takalar mengalami peningkatan signifikan dari 409.117 ton pada 2020 menjadi 619.864 ton pada 2024, dengan dominasi Cottonii sebesar 60–65 persen. Cottonii dan Gracilaria menunjukkan pertumbuhan positif masing-masing 73,9 persen dan 59,8 persen selama lima tahun, sedangkan Spinosum mengalami fluktuasi dan cenderung menurun. Proyeksi 2025–2029 memperlihatkan peningkatan total produksi dari 552.987 ton menjadi 623.476 ton, meskipun laju pertumbuhannya melambat, mengindikasikan mendekatinya kapasitas jenuh budidaya. Cottonii tetap menjadi komoditas paling potensial dengan proyeksi mencapai 575.080 ton pada 2029, sementara Spinosum diprediksi terus menurun. Temuan ini menegaskan bahwa, di tengah kecenderungan perlambatan pertumbuhan produksi dan penurunan Spinosum, kebijakan pengembangan rumput laut di Takalar perlu difokuskan pada intensifikasi budidaya Cottonii, diversifikasi komoditas melalui Gracilaria, serta penataan ulang sistem produksi untuk menghindari tekanan terhadap kapasitas lingkungan.

Abstract

This study aims to evaluate the optimization of the Lingsir Wengi MSME Market in Temuguruh Village as an economic empowerment program designed to overcome the community's dependence on bank plecit practices (illegal loans). Using a qualitative method with a case study approach, this research analyzes the supporting and inhibiting factors that influence the market's sustainability. The results indicate that functionally, the Lingsir Wengi Market has played a significant role in providing alternative livelihoods and creating economic independence, which ultimately reduces the practice of usury-based loans among the community. However, in the aspect of program management and sustainability, the market faces several serious challenges. The main inhibiting factors include the absence of a formal organizational structure or management team fully responsible for the market, lack of product innovation leading to visitor boredom, and fluctuations in the number of business actors. Meanwhile, strong supporting factors are the strategic location, full support from the Village Government, and the enthusiasm of the local community. Based on these findings, the novelty of this research lies in formulating a sustainability strategy based on local wisdom, which includes the establishment of a management team, strengthening digital marketing, and MSME human resource training to ensure long-term program effectiveness. The implication of this study is a policy recommendation emphasizing the importance of managerial professionalism in community-based economic empowerment to ensure program optimization and prevent the community from non-Sharia economic practices.

Abstract

Candle soot is a source of carbonaceous compounds that has been viewed as unwanted air pollution. Few have attempted to apply candle soot in agriculture, specifically for seed germination. This study was conducted to determine the effect of using candle soot on the germination of seeds from the Solanaceae family (Capsicum annuum, Solanum lycopersicum, and Solanum melongena). Three concentrations (10-2, 10-3, and 10-4 wt%) of candle soot were used. The results showed an improvement in measurable germination parameters and seedling quality parameters. The 10-3 wt% concentration was able to reduce the time needed for germination compared to the control by 11% in C. annuum, 12% in S. lycopersicum, and 10% in S. melongena. Further evaluation was conducted by analyzing the elements present in the seedlings. The results showed that the elemental information of seedlings treated with candle soot did not differ significantly from the control. This indicates that candle soot is biocompatible for agricultural applications. Further evaluation was also carried out to analyze biochemical components such as starch and soluble sugar, which play a crucial role in the seed germination process. The results showed a significant (p < 0.05) decrease in starch content compared to the control, while the soluble sugar content increased during treatment with candle soot. These carbonaceous particles could be a potential approach to enhancing germination and promoting sustainable agricultural practices, as revealed by this investigation.
