This study aims to determine the relationship of the amount of water flow from the boom irrigation system with an attack of bacterial leaf blight in seedlings A. crassicarpa. This research has been conducted in Kerinci Central Nursery (KCN) Plant Nursery Acacia PT Riau Andalan Pulp and Paper (RAPP) in the District of Pangkalan Kerinci, Pelalawan Riau from September to November 2014. The study was conducted experimentally using correlation method to determine the relationship of the amount of water flow irrigation systems boom (x) with an attack of bacterial leaf blight (y). The research was done by measuring the amount of water flow from irrigation boom during watering. Data were statistically analyzed by simple linear regression analysis. The results showed that the relationship the amount of water flow from the irrigation system is positively correlated boom of 36.8% (increases linearly and have not yet reached the optimum point) to the emergence of the first symptoms of bacterial leaf Keywords: A. crassicarpa, the amount of irrigation water flow and bacterial leaf blight boom

The purpose of this community service activity is to transfer knowledge and technology about artificial spawning of Mutiara Strain (Clarias gariepinus Burchell, 1822) to the Unggul Farm fish hatchery unit in Pangkalan Baru Village, Kec. Siak Hulu Regency. Kampar. This activity will be held on July 12 – August 12, 2021. The method used is direct demonstration and active participation. The spawning-stimulating hormone was Ovaprim with a dose of 0.5 ml/kg female broodstock and 0.3 ml/kg male broodstock. Artificial spawning, which is the process of removing eggs and sperm by stripping and surgery, so that the maximum number of eggs and sperm is obtained. Then fertilization is carried out, and then the eggs are incubated until they hatch which are called larvae. Artificial spawning produces larvae as many as 3 tanks with a size of 1 X 5.5 m. Natural spawning is carried out by the Unggul Farm fish hatchery unit each spawning period producing one larval tank with a size of 1 X 5.5 m. The benefits of artificial spawning are to increase the production of Mutiara strain seeds and improve the welfare of members of the Unggul Farm fish hatchery unit

Pineapple (Ananai cnmo.ms L.) is a fmit, whicli has high economic value because of its wide variety of uses. Itis not only consumed fresh, but also made into syrup, taffy, andother candies, Jam and dried into chips. Thecultivation pineapple in the Rinibo Panjang Village, Tambang District, Subprovince of Kampar, Province ofRiau still uses traditional growing and culUvication methods, which result in low productivity. Conservationand diseases control are areas that need to be iraprovcd.Thc purpose of this research Ls to identifify the diseasesbased on characteristic morphology and that attack stage at the pineapple. The research was conducted in Pestand Plant diseases Laboratory of Agricultural Faculty at Riau University.This research used survey methodbased on field area, quantity of population, and plants were produced. The results of the research indicated thatsire two type of diseases attacking the pineapple crops. The First is a leaf spot caused Curvulariamaculans,infecting some 34.6 % in the field 4, The second is decay the fruits caused Thiehviopsis paradoxa, and wasfound in 32 % of the crop in field 2.

Trichoderma pseudokoningii fungus has been tested as biological control agents against several pathogenic fungi, including the Ganoderma boninense fungus which causes basal stem rot disease on oil palm. However, in-field testing, the efficacy of antagonistic microbes still showed unstable results. Therefore, it is necessary to package antagonistic microbes in the form of formulations. This study aimed to determine the effect of storage time of flour biofungicide formulations on the viability and antagonism of T. pseudokoningii Rifai in inhibiting the G. boninense pathogenic fungus in vitro. The study was arranged in a Completely Randomized Design with 4 treatments: bagasse (F1), rice husks (F2), dregs (F4) and combinations of bagasse, rice husks and dregs (F12), with three replications. The results showed that the powder biofungicide formulation of F2 (rice husk) was able to maintain the viability of the T. pseudokoningii fungus as indicated by the high number of conidia and high growth rate compared to the other formulations. The T. pseudokoningii fungus in F2 formulation also showed the highest inhibition compared to other formulations after storage for 1 and 2 months. Keywords: biofungicide, formulation, Ganoderma boninense, Trichoderma pseudokoningii ABSTRAK Jamur Trichoderma pseudokoningii telah banyak diuji sebagai jamur antagonis pada beberapa jamur patogen termasuk jamur Ganoderma boninense yang menyebabkan penyakit busuk pangkal batang tanaman kelapa sawit. Namun, pada pengujian di lapangan, efikasi mikroba antagonis masih menunjukkan hasil yang tidak stabil. Oleh karenaya perlu pengemasan mikroba antagonis dalam bentuk formulasi. Penelitian ini bertujuan untuk mengetahui pengaruh waktu penyimpanan formulasi biofungisida tepung terhadap viabilitas dan daya antagonis T. Pseudokoningii Rifai dalam menghambat jamur G. boninense Pat. secara in vitro. Penelitian disusun dengan menggunakan rancangan acak lengkap dengan empat perlakuan: ampas tebu (F1), sekam padi (F2), dregs (F4) dan kombinasi ampas tebu, sekam padi dan dregs (F12), dengan tiga ulangan. Hasil penelitian menunjukkan bahwa formulasi biofungisida tepung F2 (sekam padi) mampu menjaga viabilitas jamur T. pseudokoningii yang ditunjukkan dengan banyaknya jumlah konidia dan tingginya kecepatan pertumbuhan dibandingkan dengan formulasi lainnya. Jamur T. pseudokoningii pada formulasi F2 juga menunjukkan daya hambat tertinggi dibandingkan dengan formulasi lainnya setelah penyimpanan 1 dan 2 bulan. Kata kunci: biofungisida, formulasi, Ganoderma boninense, Trichoderma pseudokoningii
