Face spoofing detection is critical for biometric security systems to prevent unauthorized access. This study proposes a deep learning-based approach integrating FaceNet and DenseNet201 to enhance face spoofing detection performance. FaceNet generates identity-based embeddings, ensuring robust facial feature representation, while DenseNet201 extracts complementary texture-based features. These features are fused using the Concatenate function to form a more comprehensive representation for im-proved classification. The proposed method is evaluated on two widely used face spoofing datasets, NUAA Photograph Imposter and LCC-FASD, achieving 100% accuracy on NUAA and 99% on LCC-FASD. Ablation studies reveal that data augmentation does not always enhance performance, particularly on high-complexity datasets such as LCC-FASD, where augmentation increases the False Rejection Rate (FRR). Conversely, DenseNet201 benefits more from augmentation, while the proposed method performs best without augmentation. Comparative analysis with previous studies further confirms the superiority of the proposed approach in reducing error rates, particularly Half Total Error Rate (HTER), False Acceptance Rate (FAR), and FRR. These findings indicate that combining identity-based embeddings and texture-based feature extraction significantly improves spoofing detection and enhances model robustness across different attack scenarios. This study advances biometric security by introducing an efficient feature fusion strategy that strengthens deep learning-based spoof detection. Future research may explore further optimization strategies and evaluate the approach on more diverse datasets to enhance generalization.

Crop rotation is one of the most effective agricultural and has significant benefits in improving soil fertility, assessing health and disease, and increasing the efficiency of natural resource utilization. Agricultural strategies that have important benefits in improving soil fertility, assessing health and disease, and increasing the efficiency of natural resource utilization. To maximize nutrient utilization and reduce the risk of certain pests associated with a crop, this practice involves reducing the types of crops grown on the same land in the relevant cycle. To maximize nutrient utilization and reduce the risk of certain pests associated with a crop, this practice involves reducing the types of crops grown on the same land in the relevant cycle. In addition, crop rotation helps improve soil structure, increase cation exchange capacity (CEC), and reduce dependence on chemicals and pests. The study employed a library analysis method by reviewing several previous studies on the impact of crop rotation on agricultural productivity and soil ecology. The results showed that crop rotation can increase nitrogen levels in the soil by up to 20%, reduce pesticide use by up to 50%, and increase air use efficiency, especially in areas with limited air supply. In addition, this practice helps create a more stable agricultural ecosystem by increasing biodiversity, such as reducing the number of natural enemies of pests. The findings of this study indicate that crop rotation is a practice that not only increases crop yields but also strengthens the principle of sustainability. With proper maintenance, crop rotation can be an effective solution to reduce land degradation, improve food security, and improve ecological balance in modern food systems. resilience, and improve ecological balance in modern agricultural systems.

Spinach (Amaranthus spp.) is a vegetable plant that is highly dependent on the availability of light and nutrients for its growth. Proper spacing plays an important role in influencing a plant's access to light and nutrients, which ultimately impacts its yield. This study examines the impact of planting distance on light and nutrient competition in spinach. Planting spacing that is too tight can lead to intense competition between plants, reduce the efficiency of photosynthesis, and increase the risk of etiolation in lower plants. On the contrary, planting spacing that is too wide reduces land use efficiency and increases the likelihood of weed growth. The ideal planting distance ranges from 15-20 cm between plants, which ensures maximum utilization of light and nutrients without resulting in excessive competition, thus supporting optimal growth and yield

Chili (Capsicum annuum L.) is a high-value horticultural commodity, but its productivity is often hampered by factors such as soil conditions, climate, pests and disease. The use of plastic mulch, especially the black-silver type, can increase chili yields by 25–40% through weed control, maintaining soil temperature, and reducing evaporation. Although initial costs are relatively high, significant yield increases can offset those costs. However, the resulting plastic waste is an environmental problem, so biodegradable mulch can be a more environmentally friendly alternative. This research uses a literature review method to collect and evaluate information from various relevant sources regarding the application of plastic mulch in increasing chili productivity. With proper management, plastic mulch can support increased chili yields and agricultural sustainability.

This study investigates the character, and value as a citizen and attitude of socio-scientific issues (SSI) among pre-service chemistry teacher’s in Riau, Indonesia. SSI learning was conducted in the classroom and designed to cultivate characteristics and attitude of SSI. The integration of SSI with the learning process involved instruction that inquiry analyzing based on environmental issues. A total seventy-six chemistry education majors participated in the study, including eleven male and sixty-five female students. Data were collected through a structured questionnaire that measured the participants’ characteristics, civic value, and attitude of SSIs. The collected data were analyzed using SPSS 26 with, employing descriptive statistic and Mann-Whitney U analysis. The result revealed that male pre-service chemistry teacher group has a higher score in character, value as citizens, and attitude of SSI compared to their female counterparts. However, the analysis showed no statistically significant difference (p>.05) between male and female pre-service chemistry teacher in the sub-factors of character and SSI attitudes. Despite the lack of significant gender differences, the findings suggest that the integration of SSI in chemistry education can enhance moral thinking and decision-making abilities and positive attitude toward SSI. Teachers may consider both subject matter and instructional method when addressing these aspects in the classroom.
