Analisis Efisiensi Produksi Usahatani Sagu di Provinsi Riau: Pendekatan Stokastik dan Deterministik
No full textSago is one of the potential commodities in Indonesia as a food reserve. The main issue with sago production is that it is still managed traditionally, without the application of proper cultivation techniques. Generally, sago farmers in Riau Province do not conduct adequate care and maintenance of sago plants, which affects sago productivity. This study aims to analyze the production efficiency of sago farming in Riau Province. The sampling method used was non-probability sampling with purposive sampling techniques. Data analysis was carried out using a stochastic approach with the Cobb-Douglas production function model. The results of the study show that technically, sago farmers in Riau Province are efficient in labor use but inefficient in utilizing harvest area. Therefore, it is necessary to expand the harvest area and adopt a regular planting distance using an equilateral triangle system to increase the number of clumps per harvest area. Meanwhile, allocative and economic efficiency in sago farming in Riau Province has not been achieved. The relatively small number of plant clumps and the high land prices make harvest area utilization allocatively inefficient. Although labor allocation is technically efficient, it is not efficient in terms of allocation and economics. Labor costs are relatively high; thus, to achieve efficiency, it is necessary to reduce labor cost allocation.Provinsi Riau memiliki luas areal, produksi dan produktivitas sagu tertinggi dibandingkan provinsi penghasil sagu lainnya di Indonesia. Namun usahatani sagu di Provinsi Riau pada umumnya dilakukan secara turun temurun. Sebagian besar petani sagu tidak melakukan perawatan dan pemeliharaan, sehingga berpengaruh terhadap produktivitas sagu. Penelitian ini bertujuan untuk menganalisis efisiensi produksi usahatani sagu di Provinsi Riau dengan pendekatan stokastik dan deterministik. Metode analisis yang digunakan pada pendekatan stokastik adalah model fungsi produksi Cobb-douglas. Sedangkan pendekatan determenistik menggunakan metode Data Envelopment Analysis (DEA). Hasil penelitian ini menunjukkan faktor-faktor dominan yang mempengaruhi produksi sagu adalah luas panen dan jumlah tenaga kerja. Sedangkan analisis efisiensi menunjukkan bahwa sebagian besar petani sagu belum efisien secara teknis dan tidak efisien secara alokatif dan ekonomi. Hal ini disebabkan oleh penggunaan input yang berlebih serta penerapan teknik budidaya sagu yang belum optimal. Selain itu, juga belum mampu mengkombinasikan input dengan harga input minimal. Pentingnya mencapai efisiensi ekonomis menekankan petani untuk mencapai efisiensi baik secara teknis maupun alokatif. Dengan demikian, petani dapat menghasilkan output yang optimal dengan penggunaan input yang minimal, sehingga menciptakan kondisi usahatani yang efisien

Get PDFThis study evaluates the effectiveness of the Keluarga Penerima Manfaat (KPM) social assistance program in alleviating poverty in Sumengko Village, Kalitidu District, Bojonegoro Regency, in 2023. A qualitative descriptive method was employed, with data collected through interviews, observations, and documentation involving six respondents. The evaluation utilized William N. Dunn's framework, focusing on effectiveness, efficiency, adequacy, equity, responsiveness, and accuracy, to ensure credible conclusions. The findings indicate that while the program effectively addresses basic needs by distributing 10 kg of rice per household, limitations in rice availability hinder its adequacy and equity. Uneven socialization and misallocation to ineligible households also impact program accuracy. These findings provide a basis for comparing similar programs in other rural settings and highlight the need for improved coordination and oversight. Beyond poverty alleviation, the program has potential broader impacts on community health and education by enhancing food security and reducing economic stress. This comprehensive evaluation emphasizes the importance of addressing logistical and social challenges to optimize the benefits of social assistance programs

Performance Evaluation of CNN-LSTM and CNN-FNN Combinations for Pneumonia Classification Using Chest X-ray Images
Get PDFPneumonia is one of the deadliest infectious diseases worldwide, particularly affecting children under five years old and the elderly, with a significant mortality rate annually. This disease is caused by bacterial, viral, or fungal infections, leading to inflammation in the air sacs (alveoli) of the lungs, which disrupts respiratory function. A major challenge in diagnosing pneumonia lies in the reliance on radiological expertise to interpret chest X-ray images, a process that is time-consuming and prone to errors in interpretation. This study aims to compare the performance of deep learning models, specifically the combination of Convolutional Neural Networks (CNN) with Long Short-Term Memory (LSTM) and CNN with Feedforward Neural Networks (FNN), in classifying pneumonia based on chest X-ray images. The results indicate that the CNN & LSTM model achieved an accuracy of 96.59%, a loss of 9.95%, precision of 96%, recall of 95%, and F1-score of 96%, slightly outperforming the CNN & FNN model, which achieved an accuracy of 96.13%, a loss of 12.16%, precision of 96%, recall of 94%, and F1-score of 95%. The advantage of CNN & LSTM lies in its ability to capture sequential patterns through LSTM, making it more effective in detecting positive pneumonia cases. In conclusion, the CNN & LSTM model outperforms the CNN & FNN model in accuracy, recall, and F1-score, making it a more reliable choice for automatic pneumonia classification. The findings suggest the potential use of deep learning models, particularly CNN & LSTM, to support medical professionals and the public in quickly and accurately detecting pneumonia through chest X-ray images analysi
Comparative Analysis of the Performance of Four Symmetric Algorithms on Digital File Security
Get PDFInformation security is crucial to prevent misuse that could harm others. Information can be accessed through various electronic devices such as mobile phones, computers, and tablets in the form of text, images, audio, and video, whether public or confidential. In the digital era, image files are highly susceptible to authenticity risks as they can be easily shared through various communication media. This facilitates unrestricted digital file exchange, raising concerns about authenticity and the risk of modifications before reaching the recipient. Therefore, digital file exchanges require a security system to ensure that transmitted data remains original and intact. Cryptography is a field of study that protects data security in communication. It consists of algorithms and keys, where algorithms perform encryption and decryption, while keys enhance security levels. This study examines image encryption by using different key lengths with the same image, as well as encrypting images of varying sizes using the same key length, employing AES, DES, 3DES, and RC6 algorithms. The results show that the DES algorithm is the fastest in encryption and decryption compared to the other three algorithms. DES is 13.3% faster than 3DES and 10.2% faster than RC6. Additionally, the key length used does not significantly impact processing time, but image size greatly affects encryption and decryption speed. These findings indicate that in cryptographic implementations for digital images, file size is a critical factor to consider to maintain efficiency without compromising encryption and decryption spee
