Abstract

One of the efforts to facilitate the way of taking rice seeds from the nursery media is to use plastic sacks instead of  directly from the soil.  To obtain the best planting media, experiments have been carried out on the no tidal swamp Rice   Fields, Pemulutan Village (3°05'42.7"S, 104°44'01.7"E), Ogan Ilir Regency, South Sumatra Province from June to August 2022.  The design method used was a Randomized Block Design. The treatments tested were four compositions of planting media mixtures, namely a mixture of soil with chicken manure, a mixture of black sand and chicken manure, a mixture of white sand and chicken manure, and black sand. The media composition ratio was 1:1 (V/V). All treatments were replicated three times to obtain 12 units. The seeds used are rice seeds of the Inpari 32 variety. The size of the seeding media made from plastic sacks was 160 cm x 100 cm, and the thickness of the entire planting media composition was 3 cm.  The plastic sacks used had a length of 180 cm and a width of 112 cm, and were used as a pad for a rice nursery which were 160 cm x 100 cm, and the thickness of all media compositions was 3 cm. The composition of the four treatments prior to the study showed that the pH was relatively the same (6.9-7.0) and the EC valuesvaried greatly (207-7734 mS), and at 14 day after plant (DAP) there was a decrease in pH to 4.3-5.3 and EC decreased drastically with narrow variations being (170-384 dS/cm).  Changes in the chemical properties of the media certainly had an impact on seed germination (70-90%) at 14 DAP of each media, and it turned out that the composiion of the type of planting media had  significant effect on sprout height, number of leaves, leaf length and sprout root length. In general, it can be concluded that the best media composition for rice germination is soil and chicken manure.

Abstract

This research was aimed to know the effect of Physical Scarification and Soaking Time of Coconut Water to Viability of Soursop Seed (Annona muricata L.). This research was carried out from March until April 2022 at the Greenhouse of Faculty of Agriculture University of Sultan Ageng Tirtayasa. The research used a Completely Randomized Design (CRD) consisting of two factors. The first factor was the physical scarification, which consists of 3 levels namely S0 (Without scarification), S1 (Sanding one side of the seed), and S2 (Sanding two sides seed). The second factor was soaking time of coconut water, which consists of 3 levels namely L0 (Without soaking), L1 (Soaking time 12 hours), and L2 (Soaking time 24 hours). The combination of the two factors was repeated three times, so that 27 experimental units are obtained. The result showed that the scarification treatment with sanding one side of the seed (S1) gave the best effect on the parameters of germination age (18.22 days), maximum growth potential (58.89%), power of germination (55.56%), normal sprout (51.11%), growth rate (1.70%/day), and seeds that did not grow (44.44%). The soaking time of coconut water 24 hours (L2) gave the best effect on the parameters of germination age (17 days), maximum growth potential (61.11%), power of germination (63.33%), normal sprout (54.44%), growth rate (1.81%/day), and seeds that did not grow (38.89%). There was no interaction between the physical scarification  and the soaking time of coconut water for all parameters of observed.

Abstract

Success in cultivating potatoes is the use of good quality potato seeds. Good quality potato seeds are produced through several stages starting from in vitro culture to extension seed production. One of the important stages in potato seed production is the production of first generation (G1) potato seeds. Efforts to increase the yield of G1 tubers can be made through modifying the planting media and applying growth regulators. This research aims to produce G1 potato tubers by adjusting the composition of the planting media (cocopeat, cocofiber, charcoal husk) and applying a growth inhibitor (Daminozide). The research consisted of four series of experiments. Each experiment was carried out using a Completely Randomized Design (CRD) with six treatments, each repeated four times. Experiment 1 (a. Cocopeat 100% + 0% husk charcoal; b. Cocopeat 20% + 80% husk charcoal; c. Cocopeat 40% + 60% husk charcoal; d. Cocopeat 60% + 40% husk charcoal; e. Cocopeat 80% + Charcoal Husk 20%; f. Cocopeat 0% + Charcoal Husk 100%. Experiment 2 (a. Cocofiber 100%; b. Cocopeat 100%; c. Cocopeat 20% + Cocofiber 80%; d. Cocopeat 40% + Cocofiber 60%; e. Cocopeat 60% + Cocofiber 40%; f. Cocopeat 80% + Cocofiber 20%. Experiment 3 (a. Cocopeat + Cocofiber + husk charcoal (1 : 1 : 1); b. Cocopeat + Cocofiber + charcoal husk (1 : 1 : 2); c. Cocopeat + Cocofiber + husk charcoal (1 : 2 : 1); d. Cocopeat + Cocofiber + husk charcoal (2 : 1 : 1). Experiment 4 (a. Daminozide 0 ppm; b. Daminozide 500 ppm; c. Daminozide 1000 ppm; d. Daminozide 1500 ppm). From the research results it can be concluded: 1) The combination treatment of 80% cocopeat + 20% cocofiber is the best treatment combination in the vegetative growth phase; 2) Composition treatment 60% cocopeat + 40% husk charcoal is the best treatment for the growth and number of G1 potato tubers; 3) Treatment of the composition of the planting media with cocopeat, cocofiber, and husk charcoal with a composition of 1:1:1 produces the highest number of tubers; 4) The best concentration of daminozide for the growth and production of G1 potato seed tubers is 3500 ppm.

Abstract

The response of plants to environmental stress depends on the type of plant, the level, and the duration of stress. Drought stress affects growth, development, and the content of secondary metabolites produced by the plant. Kumis kucing (Orthosiphon aristatus (Blume) Miq.) is one example of a tolerant plant to drought stress. A study was conducted to compare the effect of several drought stress levels on plant growth and its sinensetin content. For this purpose, the experiment was carried out in a greenhouse with a one-factor complete randomized design, namely the level of water availability. The treatment tested consisted of: 100; 50; 37.5; 25; 12.5 percent of field capacity. Data were analyzed using analysis of variance and further tested with the Duncan Multiple Range Test level of 5% on significant results. The High-Performance Liquid Chromatography method was employed to test the sinensetin content (in percentage). The results showed that low water availability (50-12.5% field capacity) harmed plant growth and negatively affected leaf, stem, and root dry weight. The reduction in growth was highly significant in plants with water availability of 12.5% of field capacity. In low water availability, the plant that experience drought stress produced greater sinensetin content (0.0133%). Increased sinensetin in drought stress condition is a biochemical and physiological response of plants to unfavourable conditions.

Abstract

Fungi Dreschslera oryzae or Helminthosporium oryzae often found in rice seeds and causes brown spot disease (brown spot disease). Symptoms of attack can be seen in nurseries and on mature plants. The aim of the research is to determine the effect of a consortium of biological control agents and secondary metabolites Trichoderma harzianum which is used as biopriming on rice seeds contaminated with D. oryzae. The treatment tried was without biological control agents as a control, consortium T. harzianum and A. chrococcum, consortia of three isolates Bacillus sp, consortium A. chrococcum, A. vinelandi, Azospirillum sp, Pseudomaonas cepacia, Penicillium sp, Acinetobacter sp, and secondary metabolites T. harzianum, designed using a Completely Randomized Design with five replications. The experiment used two methods, namely germinating rice seeds on gauze media and on soil media. The research results found that biopriming with the biological control agents and secondary metabolites T. harzianum on rice seeds, it has the effect of increasing shoot height, shoot fresh weight, seedling fresh weight, root length, and reducing disease intensity. In general, the use of the biological control agents and secondary metabolites T. harzianum has the same effect. The presence of chitinase enzymes and siderophore compounds in biological control agents and secondary metabolites T. harzianum has an effect on reducing disease intensity, while the hormones auxin and gibberellin have an effect on increasing shoot height, shoot fresh weight, seedling fresh weight and root length.

Abstract

ABSTRACT Red chilli (Capsicum annuum L.) is a important commodity and has high economic value in Indonesia. Obstacles in cultivating red chilli are pest attacks, namely aphids (Aphis gossypii Glover) and whitefly (Bemisia tabaci Genn.). The use of predator (Coccinella transversalis Fabricius.) can be alternative to controlling A. gossypii and B. tabaci in a safe way. This research aims to know the ability of predator C. transversalis to prey nymph of A. gossypii and nymph of B. tabaci. This research was carried out at the Plant Pests Laboratory and Green House of the Faculty of Agriculture, Riau University which was carried out for three months from Maret to Mei 2022. The study was carried out experimentally using a completely randomized design (CRD), which consisted of six treatments and four replications. The treatments used was preying ability of the predator C. transversalis against A. gossypii and B. tabaci as prey. The results showed that the C. transversalis preferred the prey of the nymph A. gossypii compared to the prey of the nymph B. tabaci. Predator C. transversalis are able to prey on 46-48 A. gossypii nymphs per day and are able to prey on 43-44 B. tabaci nymphs per day. Preying ability of predator C. transversalis as biological agents with prey A. gossypii and B. tabaci between one male, one female and one pairs predator showed no difference in predation ability.Keywords : Coccinella transversalis Fabricius., Aphis gossypii Glover., Bemisia tabaci Genn., Preying ability

Abstract

Kawista Fruits, which originates from India, were found in Pasinan village, Lekok, Pasuruan, East Java. People generally use this plant as med-icine, one of which is to cure diarrhea. That fuits has been consumed leaves quite a lot of fruit peel. One effort to utilize kawista fruit peel waste is to process into a useful material. Based on the research results, Kawista fruit peel extract at a concentration of 100% was effective in inhibiting the growth of Salmonella sp bacterial colonies. The characteristics of the raw materials for using kawista fruit peel as an antibacterial are very important to maintain the quality of the ingredients and to ensure the uniformity of their properties. Despite of that, information on the secondary metabolite content of kawista peel is also very important to know what compounds are useful as antibacterials. Based on the results of research using phytochemical analysis, the results obtained were that the secondary metabolite compounds contained in kawista fruit skin were flavonoid, terpenoid, alkaloid, saponin and tannin. Meanwhile, the results of the simplicia characterization showed that the drying shrinkage level was 10.516%, the air content was 4.778%, the ash total content was 10.918%, the air soluble essence content was 23.673%, and the ethanol soluble essence content was 12.756%. Based on standard parameter conditions, the drying shrinkage content, water content, air soluble essence content, and ethanol soluble essence content have met the standard parameters. Meanwhile, the total ash content does not meet the standard parameter requirements.
