Abstract

The use of tofu waste water using the hydroponic technique of the floating raft system is not well known, so it needs to be done as an innovation. The purpose of this research was to determine the effect of tofu liquid waste fermentation on the growth of red lettuce (Lactuca sativa L var. Red rapids) using the floating raft hydroponic technique. The research was carried out in an experimental stage, namely the effect of tofu liquid waste on the growth of red lettuce (Lactuca sativa L var. Red rapids). This research method is an experimental method using a completely randomized design (CRD) consisting of 5 treatments and 3 replications. Parameters observed were plant height, leaf width, number of leaves, root length, wet weight and dry weight. The results of the analysis of variance (Anava) at 5% level, the use of tofu liquid waste showed a significant effect on the growth of red lettuce. Giving a concentration of 2.5 liters of tofu liquid waste with 5 liters of water resulted in the best growth of red lettuce.

Abstract

Corn (Zea mays L.) is one of the most important food crops in the world after rice and wheat.There were various problem in crop production, one of which is the attack of fall armyworms (Spodoptera frugiperda J. E Smith). The alternative technique to control this was using botanical pesticide from forest betel leaf (Piper aduncum L.). This study aimede to obtain an effective concentration of forest betel leaf extract to control fall armyworm. This research was carried out at the Plant Pests Laboratory of the Faculty of Agriculture and the Laboratory of Natural materials and minerals, Faculty of Engineering, Riau University for 3 months from July to September 2021. The study consisted of six treatments 0%, 0.2%, 0.4%, 0.6%, 0.8%, 1% and four replications This research was arranged by Completely Randomized Design (CRD). The results showed that the use of forest betel leaf extract had a significant effect on the mortality of Spodoptera frugiperda larvaeConcentration of 0.8% is effective in controlling Spodoptera frugiperda larvae because it caused mortality at about 80% with an initial time of death  was 1 hour after application and a lethal time of 50 at 13.5 hours after application.

Abstract

Corn (Zea mays L.) is one of the most important food crop in the world after rice and wheat. Yield loss in corn due to armyworm (Spodoptera litura F.) in Indonesia can reach 80%. Clove leaf (Syzygium aromaticum L.) is one of the plants that have the potential as a vegetable insecticide to control pests. This study aims to obtain the concentration of clove leaf extract (S. aromaticum) with ethanol organic solvents. The research was carried out at the Plant Pest Laboratory, Faculty of Agriculture, Riau University from February to April 2022. The study was conducted experimentally using a completely randomized design (CRD) consisting of six treatments with four replications that obtained 24 experimental units. The treatments given were several concentrations of clove leaf extract with ethanol organic solvents, namely 0.0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0%. The results showed that the application of clove leaf extract with an organic solvent concentration of 0.8% (8 ml.l-1 water) was the best concentration for total mortality of S. litura based on BNJ test results at 5% level and was able to cause total mortality of 77.50% with an initial time of death of 8 hours after application and lethal time 50 at 21 hours after application, but it has not been said to be effective because it has not reached 80%. A concentration of 1% was an effective concentration for controlling S. litura. because it was able to cause total mortality of 82.50% with an initial time of death 5 hours after application and a lethal time of 50 at 17.50 hours application.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh umur dan tinggi pemotongan  pada fase vegetatif terhadap pertumbuhan dan hasil tanaman padi (Oryza sativa L.) dan analisis usahatani. Penelitian ini dilaksanakan selama 4 bulan pada tahun 2019 di Kampung Jua, Kelurahan Kampung Jua Nan XX, Kecamatan Lubuk Begalung, Sumatera Barat. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan jarak tanam 25 cm x 25 cm pada luas petak 2 x 2 m, dengan 7 perlakuan yang terdiri dari;  tidak dipotong , dipotong  saat umur 35 hst dan tinggi potong  mulai 5 cm, 10 cm, dan 15 cm. Potong  saat umur 45 hst  mulai dari  tinggi potong  5 cm, 10 cm, dan 15 cm dengan 3 ulangan sehingga terdapat 21 plot percobaan. Data diambil secara acak lengkap apabila berpengaruh nyata maka akan dilanjutkan dengan uji BNT pada taraf nyata 5%. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan terbaik adalah pemotongan  tanaman padi IR42, yang dilakukan saat 45 hst setinggi 5 cm di atas permukaan tanah mampu menghasilkan 23 t ha-1 HPT dan 5,73 t ha-1 GKG, dengan penghasilan bersih sebesar 46,45 juta rupiah untuk 1 kali panen atau 11,6 juta rupiah per bulan.

Abstract

Bacteria is a potential agent in biological organic fertilizer”s process. The rate of decomposition of organic matter in biological organic fertilizers process depends on the role of funtional bacteria, the type of organic matter and the microenvironment.  Bacteria that are inoculated into biological organic fertilizer’s matter must be synergistic among them, so that their role as as bioactivators more efficient.  A compatibility experiment among the bacteria isolates used as bioactivators have to be done in order to  obtain an effective and efficient biological organic fertilizer. The objevctive of the research is to obtain information on the compatible nature of the bacterial isolates. The research was conducted at the Plant Protection Laboratory of the Payakumbuh State Agricultural Polytechnic, West Sumatra from July to August 2022. The research method began with the rejuvenation bacterial isolates of Bacillus cereus, Bacillus subtilis, Bacillus thuringiensis on NA media, then continued with a compatibility experiment  using the dual culture method on NA and King’s B medium, so there were a total of 12 treatments (single and combination) with three replications. The results of the compatibility experiment on the three Bacillus bacteria did not form a halo inhibition zone and were compatible with the compatibility index value (IK) 0.67-1 on NA medium and 0.90-1.00 on King’s B medium, meaning that the growth between the three Bacillus bacteria did not inhibit each other, so that all Bacillus bacteria could be used as a bioactivator simultaneously in biological organic fertilizer’s process.

Abstract

The low productivity and long harvesting period of local black rice causes this plant to be rarely cultivated by farmers in Indonesia. One way to increase the genetic diversity of black rice is by using gamma ray irradiation. This study aims to determine the genetic diversity and heritability value of M2 generation black rice resulting from gamma-ray irradiation. The research was conducted in February - June 2021 at the Screenhouse Universitas Perjuangan Tasikmalaya. The genetic material used was black rice M2 generation resulting from gamma ray irradiation with doses 200 gy and PH5 as a control. The research was conducted in 2 experimental stages. The first experiment was in the nursery where M2 seeds were planted with 1000 seeds and 200 seeds for the control. In the second study, the M2 generation black rice mutant was planted with 250 seedlings without replication and the control 10 plants were repeated three times. The results showed that there was a chlorophyll mutation in the M2 generation lines which produced color variations including albino 0.5%, xantha 42%, viridis 5%, tigrina 0.5%, normal 52% at 21 HSS. The survival ability of the black rice mutant was smaller than that of the control. The heritability values in the broad sense of the high category and high genetic diversity were found in the number of productive tillers, the number of total grain, and the number of empty grain. M2 generation black rice irradiated with 200 gy gamma rays was able to provide a response of longer flowering time, narrower flag leaves, lower weight per plant, less filled grain, and increased number of empty grain compared to control (PH5).
