Abstract

Rice is one of the most important staple crops in Indonesia. Rice is the main source of food for the majority of Indonesia's population, including the Stabat area, which is a small town part of Langkat Regency, North Sumatra Province. Rice itself needs water to grow and develop, and is a plant that is no stranger to pests in the form of birds, mice, javelin, and so on. In dealing with pests, farmers in Stabat usually still use traditional methods by installing scarecrows and using pesticides to kill the pests. The work carried out by always going to the fields takes up a lot of energy and time from farmers. The University of North Sumatra Community Service Team offers a solution, namely making tools to protect rice plants from pests (javelin, aphids, caterpillars, mice, fungi) using pest detection sensors to help farmers in caring for rice to maintain the quality and quantity of rice through spraying pests to reduce losses incurred by farmers, especially during the harvest period. Solar energy-based pest control tool to improve the quality of rice plants to reduce losses. Farmers can also reduce the spraying of rice pests using chemicals so that soil fertility is maintained

Abstract

A tailwind, a wind component in aviation, can pose risks during aircraft takeoff and landing by blowing from the aircraft's rear. At Kualanamu Airport on August 02, 2022, Air Navigation Indonesia (AirNav) reported an incident where an aircraft had to abort landing due to a tailwind on the runway. This study analyzes the atmospheric dynamics contributing to tailwind disruptions on that specific day. The analysis involved various steps, including assessing upper-level air humidity using reanalysis data processed with the GrADS application, evaluating air instability through the computation of TT, KI, and SI indexes using the RaOB application, and examining cloud formation using Himawari-9 EH satellite imagery. The analysis revealed the presence of Cumulonimbus clouds around Deli Serdang Regency on August 02, 2022, which led to tailwind effects at Kualanamu Airport. Cumulonimbus clouds are often associated with unstable atmospheric conditions and can generate severe weather events like thunderstorms, heavy rainfall, and strong winds. Cumulonimbus clouds indicate the likelihood of convective activity and strong winds. The strong winds caused by these clouds probably disrupted the Tailwind on the runway at Kualanamu Airport.
