The alumni information system plays a crucial role in maintaining communication between alumni and educational institutions. Currently, alumni data management at the Information Systems Study Program of UIN Sulthan Thaha Saifuddin Jambi is still conducted manually using Google Forms and WhatsApp groups, leading to difficulties in data recording and updates. Therefore, this research aims to develop a web-based alumni information system to enhance the efficiency of alumni data management, information dissemination, and communication between alumni and the institution. This study employs the Rapid Application Development (RAD) method, which consists of three main stages: requirement planning, system design, and implementation. The system was developed using the CodeIgniter framework and a MySQL database to ensure security and efficiency in alumni data management. The results of testing using the Black Box Testing method indicate that the system functions according to the designed specifications. Additionally, the results of the User Acceptance Testing (UAT) show that 96% the system is well accepted by users as it provides easy access to alumni information, job vacancies, as well as feedback and suggestions. This system is expected to strengthen the relationship between alumni and the institution while offering more effective and structured alumni data management.

The National Health Insurance (JKN) system is a strategic program of the Indonesian government to ensure equitable access to healthcare services for all citizens. However, the sustainability of JKN financing faces challenges due to rising healthcare costs, particularly from non-communicable diseases (NCDs). One potential solution is to utilize fiscal instruments such as excise taxes, especially on sugar-sweetened beverages (SSBs), which are known to contribute significantly to the burden of NCDs. This study aims to analyze the legal framework and urgency of utilizing excise revenues from sugar-sweetened beverages (SSBs) to support JKN financing. Using a normative juridical method and a statutory, conceptual, and comparative approach, this research explores relevant laws and public health data. The findings reveal that although the allocation of excise on SSBs for JKN is not yet explicitly regulated, the existing legal framework—particularly the pattern of cigarette tax and tobacco excise revenue allocation—provides a strong precedent. From a medical perspective, high SSBs consumption has been shown to increase the risk of NCDs, placing a significant burden on JKN. Therefore, implementing MBDK excise not only aligns with public health goals but also holds fiscal potential to support sustainable healthcare financing.

Soil moisture is a crucial factor in agriculture that affects plant growth and crop productivity. In modern agricultural systems, accurate soil moisture monitoring is essential for optimizing water usage and enhancing the efficiency of automatic irrigation systems. This study aims to develop an Internet of Things (IoT)-based soil moisture monitoring system and evaluate the performance of three types of soil moisture sensors: Soil Moisture FC-28, Capacitive Soil Moisture Sensor, and Soil Moisture Hygrometer Module Sensor. The evaluation compares the accuracy and effectiveness of each sensor in measuring soil moisture. The research methodology involves measuring soil moisture in ten different soil samples using the three sensors simultaneously. The system is based on the ESP32 microcontroller, where data from the sensors are processed and displayed on an LCD Liquid Crystal I2C 20x4. Data analysis is conducted using the one-way ANOVA statistical method to determine whether there are significant differences among the measurement results of the three sensors.The results indicate that each sensor exhibits different measurement characteristics based on its working principle. The Soil Moisture FC-28 sensor, which operates on resistance, shows high sensitivity to changes in soil moisture but is susceptible to corrosion. The Capacitive Soil Moisture Sensor is more durable as it does not have direct contact with the soil, yet it requires more precise calibration. Meanwhile, the Soil Moisture Hygrometer Module Sensor provides more stable results under various environmental conditions. The one-way ANOVA analysis reveals no significant differences in the measurement results among the three sensors.

Baja karbon ST 40 sering digunakan dalam industri pembuatan kapal, khususnya untuk konstruksi lambung dan dek kapal. Mengingat bahwa lambung adalah bagian pertama dari kapal yang bersentuhan langsung dengan air laut, maka bagian ini memiliki risiko tinggi terhadap korosi. Penelitian ini bertujuan untuk mengetahui laju korosi baja karbon ST 40 (40 mm x 40 mm x 4 mm) dalam sampel air laut yang diambil dari Pelabuhan Gresik. Korosi sangat memengaruhi umur pakai baja dan besi, sehingga penelitian ini menjadi penting. Penelitian ini menggunakan metode kehilangan berat (weight loss method) dan proses perendaman dengan menggunakan pengaduk magnetik (magnetic stirrer) dan tanpa pengaduk magnetik untuk mengukur laju korosi. Pengukuran dilakukan setiap 7 hari selama 28 hari. Hasil penelitian menunjukkan bahwa laju korosi tertinggi terjadi pada air laut dengan pengaduk magnetik, dengan nilai laju korosi (CR) sebesar 13,72 mpy, sedangkan laju korosi terendah terjadi pada air laut tanpa pengaduk magnetik, dengan nilai CR sebesar 0,19 mpy. Selain itu, analisis regresi linier menunjukkan bahwa laju korosi pada air laut dengan pengaduk magnetik adalah -37 mg/cm², dibandingkan dengan -6,06 mg/cm² tanpa pengaduk magnetik. Temuan ini mengonfirmasi bahwa penggunaan pengaduk magnetik mempercepat laju korosi pada baja karbon ST 40.
