Abstract

Cuaca ekstrem merupakan salah satu fenomena hidrometeorologi yang berdampak signifikan terhadap kehidupan masyarakat di Indonesia. Penelitian ini bertujuan untuk mengetahui potensi bencana cuaca ekstrem berupa angin puting beliung di Kabupaten Ogan Ilir dengan menganalisis parameter terkait menggunakan pendekatan Sistem Informasi Geografis (SIG). Parameter yang digunakan dalam penelitian ini meliputi tutupan lahan, kemiringan lereng, dan curah hujan. Metode yang digunakan seperti overlay dan skoring berdasarkan pedoman Perka BNPB Nomor 2 Tahun 2012. Data diperoleh dari berbagai sumber seperti Badan Informasi Geospasial (BIG) dan Climate Hazards Group InfraRed Precipitation with Station (CHIRPS). Seluruh data diolah menggunakan Software ArcGIS 10.8. Hasil penelitian menunjukkan bahwa seluruh wilayah Kabupaten Ogan Ilir tergolong dalam kategori bahaya tingkat  sedang dengan luas total 224.415,51 hektare atau 100% dari total wilayah. Klasifikasi ini dipengaruhi oleh dominasi curah hujan menengah sekitar 74,21%, kemiringan lereng datar sekitar 93,59%, serta tutupan lahan berupa tanah terbuka dan sawah.

Abstract

One of the strategies issues that determines the success of a rice crop is how to eradicate pests without using chemicals. Conventional pest control generally uses pesticides that can cause pest resistance, increase production costs, and risk environmental pollution. This study proposes an early detection system for planthopper pests based on the ADXL335 accelerometer sensor to detect vibrations or abnormal movements in rice stalks. Vibration data detected by the ADXL335 is processed together with wind speed data from the Anemometer Sensor to distinguish between vibrations caused by pests and vibrations from wind gusts. If a pest anomaly is detected, the system will automatically activate a Light Trap to physically capture the pests. Furthermore, real-time notifications are also sent to farmers via radio waves via the Telegram short message service. This system is expected to reduce dependence on pesticides, save costs, and support the government's agenda of modernizing agriculture to maintain national food security.

Abstract

Kekeringan yang terjadi secara berkepanjangan berpotensi menurunkan produktivitas pertanian dan mengganggu kesejahteraan masyarakat yang bergantung pada sektor ini. Kabupaten Ogan Ilir, Provinsi Sumatera Selatan  dikenal sebagai salah satu daerah penghasil karet yang dapat terdampak oleh kondisi tersebut. Penelitian ini menggunakan metode Analytical Hierarchy Process (AHP) yang dipadukan dengan Sistem Informasi Geografis (SIG) untuk menganalisis potensi kekeringan di Kabupaten Ogan Ilir berdasarkan lima parameter, yaitu curah hujan,  kemiringan lereng, jenis tanah, penggunaan lahan, dan jarak terhadap sungai. Hasil penelitian menunjukkan bahwa daerah Kabupaten Ogan Ilir didominasi oleh tingkat potensi kekeringan yang rendah dengan luas sekitar 123.271 hektar atau sebesar 61,47% dari total wilayah. Untuk tingkat potensi sedang mencakup sekitar 73.521 hektar atau seluas 36,66% dari total luas wilayah, sedangkan tingkat potensi tinggi hanya mencakup sekitar 3.743 hektar atau sebesar 1,87% dari total luas wilayah.

Abstract

Rapidity in technological aspects encourages industrial sector to utilize and apply the latest technology to accelerate and optimize production in its field. Thus, waste from industry polluting various aspects of environment, such as water, gives rise to environmental impacts. Heavy metals, including iron, are one of the most common and dangerous pollutants often found in water environments. Therefore, consideration of methods for heavy metal separation from water becomes important. The adsorption method has been used for separating heavy metals because of its simplicity, thus effectively cuts energy consumption and costs in process. However, heavy metal characteristics in water can vary depending on the element. Consequently, understanding the heavy metal characteristics in water is important, hence capable of formulate appropriate and effective adsorption systems. This study, Fe(III)-IIPs was applied to adsorb and separate iron from water through repeated adsorption with parameter improvements. The pH parameter plays an important role, with ion competition happens at pH <2 and the formation of iron hydroxide species at pH >4.5, which results in adsorption inhibition. The modeling of adsorption kinetic equation was found that the adsorption system carries chemisorption characteristics, with adsorption capacity of 11.15 mg/g and reaction rate constant of 19 min-1.
