HIMASITA IPB Holds a Professional Study Responding to the Brown Planthopper Pest Attack

The IPB Plant Protection Student Association (HIMASITA) held a Professional Study 1 with the theme of the Peak of Brown Planthopper Attack (Nilaparvata lugens) 2021. This activity is a work program of the HIMASITA Professional Division and was held twice, Professional Study 1 was held on Saturday, March 27 2021 which was attended by 99 IPB University students, 27 Sriwijaya University students, 8 Lampung University students, 1 Hasanuddin University student, 1 person from the People's Coalition for Food Sovereignty and 11 people from the General.

Speakers who attended the Professional Study 1: Peak Attack of Brown Planthopper (Nilaparvata lugens) 2021, namely Dr. Ir. Hermanu Triwidodo, M. Sc, Anik Wiati S.P., and Bayu Aji Krisandi. Dr. Ir. Hermanu Triwidodo He is a WBC Pest Expert Lecturer, Department of Plant Protection, Faculty of Agriculture, IPB University. Anik Wiati S.P. is an alumni of Plant Protection batch 48 and a field practitioner. Bayu Aji Krisandi is a Plant Protection student, batch 53 and the Coordinating Minister for Service and Service for BEM KM IPB in 2019/2020.

The activity was opened with great fanfare by the MC, namely Sri Roro Aminah Adiningtyas, PTN 55 student and Richo Deo Arizona, PTN 56 student, then continued with recitation reading by Vito Montana, PTN 56 student then singing the song Indonesia Raya and Hymne IPB. The Head of Himasita's Report was delivered followed by a speech by Mr. Dr. Ir. Ali Nurmansyah, M.Si, as the Head of the IPB Plant Protection Department, then explained the activities by the Professional division. The event was continued by a moderator, namely Pahmi Idris, a plant protection student, class 54. The first event began with an explanation of material by Ms. Anik Wiati, S.P, regarding the Threats of WBC to the Decrease in Rice Productivity in Tuban. He said that in early 2021 his area, namely Senori sub-district, Tuban regency, was shocked by the brown planthopper attack that occurred in January - February, why was there a scene? This is because the affected rice reaches ± 90 DAS in age. The rice has started to fill and farmers just need to harvest, but the rice is experiencing symptoms such as burning, wilting, brown, and dry. Farmers only allow and do not control because the plants are old. From several images that have been observed, there are 4 points that can be concluded, namely 1) the heaviest symptom of WBC occurs in glutinous rice 2) WBC attacks in my area only occur in rainfed type 3) WBC attacks only occur in rice planted earlier 4 ) In my own plot with a rainfed rice field type, there was no toilet attack because from the start, like the seed treatment using PGPR, the second curing we gave Lecafit, after that we continued to spray the nursery with Lecafit and Beuveria sp. which serves to maintain plant health. At the end of the session, he hoped to find a solution to overcome WBC pests.

The second event was followed by the presentation of material by Bayu Aji Krisandi with a discussion of WBC Threats on decreasing productivity in the Tuban area. he as a trigger in the 1st Professional Study discussed the tragedy of the planthopper attack in Purwabakti Village, Bogor Regency and presented the conditions of attack in the field and based on field observations the tier kebo variety is the preferred variety by WBC compared to the Inpari 30 variety. There are environmental conditions in the rice fields that support the development of brown planthopper attacks. He explained about the threat of WBC on the decline in rice productivity in the Bogor area. The third event presented material on the Prevention and Anticipation of WBC Pest Attacks on Rice Plants. Mr. Hermanu opened with his message that Negligent Blai Sembara Cilaka (forgetting to bring disaster recklessly reaps disaster). The explosion of brown planthopper pests increases if the control carried out in the field uses a lot of synthetic pesticides, the prevention of leafhoppers recommended by Mr. Hermanu, namely returning the straw to the fields, avoiding the use of pesticides, not planting foreign varieties because they are not resistant to pests and diseases plants in Indonesia. The presentation of the material was continued by discussing predictions of brown planthopper attacks and continued with active discussions by the participants. The first question discusses the brown stem planthopper which can be identified by molecular fingerprints because it may have formed tribes in different areas. This WBC attack occurred in early 2021 so farmers were shocked by this phenomenon. The second question discusses that this WBC pest can disappear in a few moments. The loss of WBC pests can be caused by flying to other areas looking for new food sources, namely vegetative stage rice because these insects can fly up to 30 km but are also often carried by the wind. How to avoid planthopper pests by applying a spacing of 30 to 40. The third question was mentioned by Mrs. Siti Herlinda that in the Rawalebak area they had never been attacked by WBC pests, this was due to the inability of farmers to buy synthetic insecticides so that the potential for pest explosions tended to be absent, different from in the region. Banyuasin, with the use of synthetic insecticides at high intensity, actually causes predators and natural enemies to die. The fourth question was discussed by Mr. Ali Nurmansyah that building an early warning system requires data some time before. It must be observed the WBC population, rice varieties, environmental conditions (temperature and humidity), the state of natural enemies, the environment around the rice planting, the distance of the plants and the intensity of insecticide spraying. This can help predict pests and their level of attack. The attack data must be complemented by the attack area. So that it is not enough to build an early warning system because the data is incomplete. So that it is hoped that students can record the data as complete as possible. After the question and answer session, the moderator conveyed the conclusion that the attack of the brown planthopper is getting more violent. The varieties used and the irrigation flow system affect the rate of attack of the brown plant hopper. Rice that is attacked by brown planthopper generally drops 50 DAS. The application of insecticides can not intelligently help the development of the brown planthopper to become more rapid and even become a frightening specter for farmers. After the question and answer session, it was continued with the delivery of certificates to the speakers and documentation of all participants present. The event was closed with recitation reading delivered by Rizki Setiawan, a 56 PTN student and ended with greetings by the MC.

The activity of the Kerofesian Study Webinar 1: The Peak of Brown Planthopper (Nilaparvata lugens) attack in 2021 received a good response from the participants. Participants looked enthusiastic during the webinar activities. Through Webinar Kerofesian Studies 1: Peak Attack of Brown Planthopper (Nilaparvata lugens) in 2021, we hope that participants can increase their understanding and concern for the importance of plant health, increase knowledge about disease prevention efforts that must be carried out appropriately and sustainably from agricultural and economic aspects, and can be a forum for channeling ideas and thoughts on the importance of plant health in Indonesia and preventing the spread of plant pests and diseases through globalization of trade.
