Abstract

Chili is one type of vegetable that is often cultivated by farmers because of its high economic value and high nutritional value. Anthracnose (Colletotrichum spp.) is the main disease that often attacks large chili plants which can cause yield loss and destroy all cultivated plants. This study aims to determine the effect of the plant refugia kenikir (Cosmos caudatus) combined with plant spacing to avoid anthracnose disease. The method used was a factorial randomized block design (RAKF) with 2 factors, Refugia kenikir (C. caudatus) (R) and Planting Distance (J), there were 6 treatments and 4 groups so that there were 24 experimental units with each unit planted 4 plants, so we got 96 plants. Which was tested by observing the percentage of disease incidence and wet weight of fruit. The results showed that refugia kenikir (C. caudatus) plant spacing combination had no significant effect on the incidence of anthracnose disease, but the spacing treatment did affect the wet weight of fruit observed on days 105 and 120 with the highest average production in treatment J3R1 (60x120 cm). ; 60 kenikir trees) of 63.5 grams and 91.25 grams.

Abstract

Eggplant (Solanum melongena L.) The demand for eggplant was increasing, but the availability of eggplant is low so it cannot be fulfilled. One of the causes of low eggplant production is due to the attack of wilt disease on eggplant plants caused by Fusarium oxysporum. Symptoms include wilted leaves, yellowing leaves and brown root and stem tissue. Control that is often done is to use pesticides (fungicides) which can cause environmental pollution. One control of Fusarium spp. wilt disease. with microbial antagonists. This research was conducted to determine the ability of isolates of rhizobacteria Pseudomonas fluorescens group (PF) and Bacillus spp. from bamboo, chili and ferns inhibited the growth of Fusarium spp. in vitro. Completely Randomized Design (CRD) with isolates of Pseudomonas fluorescens group and Bacillus spp. each 4 treatments, control. Testing the inhibitory power of isolates of Pseudomonas fluorescens group and Bacillus spp. carried out by the challenge method and in vitro. Observations were made on the percentage of inhibition of rhizosphere bacteria (DH) after incubation for 7 days. All isolates of Pseudomonas fluorescens group and isolates of Bacillus spp. Has different inhibitory power on the fungus Fusarium spp. The isolates of Pseudomonas fluorescens group derived from bamboo roots from the Palem area (KPBP) (81.95%) were isolates that had the highest percentage of inhibition and Bacillus spp. derived from chili roots from the Guntung Manggis area (BGTP1) (70%) was the isolate that had the highest percentage of inhibition.

Abstract

The productivity of mustard (Brassica juncea L.) in Indonesia has increased in 2015-2018, in line with the increasing demand for this vegetable. One of the obstacles in the cultivation of mustard is the attack of leaf destroying pests. An alternative solution to control pests is to use natural ingredients from the galam plant (Melaleuca cajuputi Roxb.). The purpose of this study was to examine the effect of galam leaf insecticide to suppress leaf destroying pests on mustard plants. The study used fresh galam leaf extract as the main ingredient in the manufacture of vegetable insecticides, which were applied in various doses. The research place in a vegetable plantation, Guntung Payung Village, North Loktabat District, Banjarbaru and was carried out for 40 days from seeding to harvesting. This study used an experimental method with a one-factor Completely Randomized Design (CRD) consisting of 5 concentration treatments and 2 controls with 4 replications. The results showed a very significant effect on the intensity of pest attack on the 4th observation. The intensity of the attack of mustard leaf destroying pests from the highest to the lowest was shown by water control (K) treatment of 26.6%, galam leaf extract 10% ( G5) 21.3%, Galam leaf extract 6% (G3) 20.5%, Galam leaf extract 8% (G4) 17.7%, Galam leaf extract 2% (G1) 15.3%, Galam leaf extract 4 % (G2) 14.2% and Chemical control (M) 7.9%.

Abstract

Chili plants are plants that are very popular with farmers because they have high economic prices and are easy to cultivate in the highlands and lowlands. One of the chili pest attacks is the whitefly (Bemisia tabaci Gennadius) which is a virus vector that can reduce chili production. Whitefly pest control (Bemisia tabaci Gennadius) still uses chemical pesticides so that alternative controls are needed using vegetable pesticides, one of which is shallot skin extract. The treatment used in this study consisted of 5 treatments namely water control, chemical control and 3 treatments with shallot skin extract concentrations (2%, 4% and 6%) which were repeated 4 times. This study used two application methods, namely the application of shallot skin extract directly to the plant and the application of shallot skin extract directly to the test insect (Bemisia tabaci Gennadius). The results of the study showed that onion skin extract had the highest mortality, namely 27.5% by direct application to plants and 35% by direct application to test insects (Bemisia tabaci Gennadius). at the concentration of shallot skin extract 6%.

Abstract

This research aims to determine the effect of providing various types of MOL on arthropod diversity in shallot plants in peatlands. This research used a one-factor completely randomized design (CRD), which consisted of four treatments which were repeated five times, so there were 20 experimental units. Each experimental unit consists of 28 plants, so the total number of shallot plants is 560 plants. Treatment consisted of t0: Control, t1: Giving 10 ml MOL leri water, t2: Giving 10 ml MOL leri water+banana stems, t3: Giving 10 ml MOL leri water+fish waste. To determine the diversity of arthropod populations due to MOL administration during observation. Arthropod data resulting from observations or identification are grouped by order and family and presented in tabular form. Next, a diversity analysis was carried out using the species diversity index, species richness, species evenness and dominance. In the observation results, there was no real influence on the diversity of arthropods on shallot plants in peatlands where local microorganisms were applied. The highest diversity of arthropod species was in treatment t2 (1.73), the highest richness of arthropod species was in treatment t1 (2.17), the highest evenness of arthropod species was in treatment t2 (0.94) and the highest dominance was in treatment t0 (0, 25).
