Coastal areas and small islands in Indonesia, reaching approximately 17,000 islands, will be directly affected by increasing sea levels, seawater intrusion, and salinization. This paper provides insight into salinity and its effect to plant, saline-tolerant animal feed crops' characteristics, adaptation mechanisms, and some proposed strategies to deal with salinity issues. This research was conducted through literature study and data were analyzed descriptively. Salinity affects the photosynthesis process, thereby decreasing the net Photosynthetic Rate (Pn), the stomatal aperture, Fv/Fm (efficient quantum), and quantum yield (light intensity/rate of photosynthesis). Salt-stressed plants can be seen from the severity by measuring the levels of Cl and Na in the roots, leaves, and chlorophyll. Plant tolerance to salinity is divided into two groups: glycophytes that are tolerant of low salt levels and halophytes that are tolerant of high salts. Salinity inhibits cell enlargement and division, increases plant mass, and increases protein and nucleic acid production. The plant adapts to saline stress, including osmotic adjustment, stress protein, free radical oxidative species (ROS) removal, ABA synthesis, and cross-adaptation. Increasing the productivity of animal feed in saline areas could be achieved in various ways by modifying water, land, chemical and biological properties, and farmer habits.

The fiqh principle “اليقين لا يزال بالشك” (faith is not lost due to doubt) is a basic principle in Islamic law that aims to ensure legal certainty in various aspects of life. This study attempts to explore the epistemological basis of this principle by examining its definition, textual basis, and practical application in the context of state governance. This study uses a normative method through literature review and comparative analysis. The research findings show that this principle plays an important role in the legal system, especially in upholding the principle of presumption of innocence, policy consistency, and legal protection of citizens. However, there are several exceptions in its application, such as in ritual worship, social transactions (muamalah), emergency conditions, and the issuance of religious fatwas. This study concludes that although Islamic law emphasizes certainty, it still maintains adaptive flexibility in responding to the changing realities of society.

The application of artificial intelligence (AI) technology has become prevalent across various sectors, including transportation and smart city. A key implementation of AI in this domain is traffic monitoring, often relying on license plate recognition to identify vehicles. However, this approach faces limitations when plates are obscured. To address this issue, this research explores a broader approach by recognizing general vehicle attributes, ensuring more accurate identification and comprehensive traffic statistics. The proposed solution integrates the You Only Look Once (YOLO) object detection algorithm and convolutional neural networks (CNN) pretrained models for vehicle attributes recognition. This study utilizes multiple datasets, including Roboflow Vehicle, Stanford Cars, VehicleID, and VCoR, to ensure comprehensive model evaluation. Experimental results indicate that YOLOv7 achieved a mean average precision (mAP) score of 86.1% for vehicle detection, with an average precision (AP) score of 91.5% for the car class. For vehicle make and model recognition, the lightweight EfficientNetV2S model demonstrated the highest accuracy score, achieving 89.8% and 99.2% on the Stanford Cars and VehicleID dataset, respectively. For vehicle color recognition, DenseNet201 models achieved the highest accuracy score of 87% on the VCoR dataset. These findings underscore the effectiveness of integrating YOLOv7 and CNN models for robust vehicle detection and recognition. This research provides a practical solution to the limitations of traditional license plate recognition methods, contributing to the development of more accurate and efficient traffic monitoring systems. Future studies may further optimize the framework for real-time applications and diverse traffic scenarios.

Ketersediaan air sangat berperan dalam siklus hidrologi lingkungan, dimana dalam konsepnya menyatakan jumlah air disuatu luasan tertentu dipermukaan bumi dipengaruhi oleh besarnya air yang masuk (input) dan keluar (output) pada jangka waktu tertentu. Ketidakseimbangan air dapat menyebabkan terjadinya kelebihan (surplus) dan defisit (kekurangan air) dan dapat berdampak pada berbagai sektor, salah satunya di sektor pertanian tanaman pangan yakni terjadinya pergeseran musim dan perubahan pola tanam. Dampak tersebut dapat diminimalisir bila dilakukan pengelolaan yang baik terhadap lahan dan lingkungannya yakni melalui perhitungan kondisi neraca air dalam suatu wilayah. Penelitian ini bertujuan untuk (1) menganalisis sebaran spasial neraca air lahan di wilayah hujan tipe D, (2) menetapkan Waktu dan Pola Tanam berdasarkan Neraca Air lahan Padi dan Palawija di wilayah hujan tipe D. Penelitian ini menggunakan metode survei dan analisis perhitungan neraca air. Hasil penelitian menunjukkan bahwa surplus air di wilayah Kecamatan Palangga dan Baito memiliki periode surplus 8 bulan dengan nilai 192, 40 mm/bulan yang terjadi pada bulan Juni dan terendah 2,04 mm/bulan yang sebarannya meliputi semua titik pengambilan sampel adapun secara administrasi meliputi desa Kiaea, Watudemba, Watumerembe, Wawonggura, Eewa, Onembute, Anggondara, Mekar Sari, Wawouru, Aosole, Sanggi-sanggi, Palangga, Tolihe, Sambahule, Matabubu, Mekarjaya, Wonua Raya, Ahuangguluri, Amasara, Wawouru, Mekarsari, Anggondara, Aosole, Eewa dan Onembute.
