Abstract

Flood disasters are a natural phenomenon that often occur in various regions in Indonesia, including cities such as Banjarnegara, Boyolali and Karanganyar. Floods have a significant impact on the economy, social and environment. Therefore, proper understanding and analysis of the factors that cause flooding is very important for effective mitigation efforts. This research uses a decision tree algorithm to analyze meteorological data including temperature, wind speed, humidity and rainfall from various cities in Indonesia. This data includes normal to hot temperature conditions, slightly calm wind speed to light gusts, high to moderate humidity, and extreme to very high rainfall. The results of the analysis show patterns and relationships between these variables and flood events. The decision tree algorithm is used to build a prediction model in the form of a decision tree, which makes interpretation and decision making easier. This research aims to identify the main factors that contribute to flooding and develop a prediction model that can be used to improve preparedness and response to flood disasters. By understanding the patterns and factors that cause flooding, it is hoped that more effective mitigation measures can be implemented to reduce the risk and impact of this disaster.

Abstract

Salah satu alternatif dalam peningkatan efisiensi pemupukan adalah penggunaan nitrogen lepas lambat. Elisitor dapat meningkatkan penyerapan nutrisi dari tanah, ketahanan tanaman pada serangan hama dan penyakit serta mengurangi pemakaian pupuk kimia sintetis. Tujuan dari penelitian ini adalah untuk mengkaji pengaruh aplikasi pupuk nitrogen lepas lambat dan bio elisitor (biosaka) terhadap fisiologi dan hasil produksi pada dua varietas tanaman padi yaitu Inpari Unsoed P20 Tangguh dan Inpari 47 WBC. Penelitian dilaksanakan di lahan Kebun Benih Bojongsari BBTPH Wilayah Banyumas menggunakan metode eksperimental rancangan acak kelompok faktorial (RAK) yang meliputi 12 kombinasi perlakuan dengan tiga ulangan. Hasil penelitian menunjukkan bahwa pemberian N-ZEO-SR Plus memperbaiki aspek fisiologi dan meningkatkan hasil tanaman padi sebesar 47,86% pada level N-ZEO-SR Plus 500 kg ha-1. Pengaruh bio-elisitor terhadap gabah kering giling (GKG) berkaitan dengan N-ZEO-SR Plus. Terdapat saling keterkaitan antara varietas, bio elisitor dan N-ZEO-SR Plus pada fisiologi tanaman padi. Penggunaan pupuk N-ZEO-SR Plus dan bio elisitor pada dua varietas padi tidak berpengaruh terhadap kesehatan tanaman. ABSTRACT One of the alternatives to improve fertilization efficiency is the use of slow-release nitrogen. Elicitor can increase nutrient absorption from the soil, plant resistance to pests and diseases, and reduce the use of synthetic chemical fertilizers. This study aimed to examine the effects of slow-release nitrogen fertilizer and the bio-elicitor (biosaka) on the physiology and yield of two rice varieties (Inpari Unsoed P20 Tangguh and Inpari 47 WBC). The research was conducted at the Bojongsari Seed Farm, BBTPH Banyumas Region, using an experimental design with a factorial randomized block design comprising 12 treatment combinations and three replications. The results showed that applying N-ZEO-SR Plus improved physiological parameters and increased rice yield by 47.86% at a rate of 500 kg ha-1. The effect of bio-elicitors on dry-milled grain was related to N-ZEO-SR Plus. There was a relationship between varieties, bio-elicitors, and N-ZEO-SR Plus on rice plant physiology. The use of N-ZEO-SR Plus fertilizer and bio-elicitors on two rice varieties did not affect plant health.
