Abstract

The aim of this study the first is to know the different effects of treatment with red-blue LED and then compare it to treatment with white fluorescent light for green mustard growth, and the second is for determined the composition from each different treatment to reach the optimum growth of green mustard in the plant factory environment. In this case, treatment with fluorescent light will be used as a control variable for the observation. The research parameter is air temperature, light intensity, and the plant's physical measurements such as diameter and height. This study used a Single Plant Design, the treatment specified in this research was a planting model consisting of the first indoor hydroponic planting model or Plant Factory by applying LED (M1) irradiation, the second outdoor planting model in a greenhouse using full sun irradiation. (M2), and the third cropping model uses direct planting in the field (M3), and the fourth cropping model uses hydroponic planting in open spaces (M4). The result showed that cultivation with the plant factory model produced the best stover wet weight, which was 165.33 g, in contrast to the greenhouse planting model which produced a wet stover weight of 97.33 g and was different from the conventional model, which was 47.33 g. Vegetable wet weight is decent. Consumption also produced the highest with the plant factory planting model, which was 159.67 g per plant, followed by the greenhouse planting model, which was 92.33 g, and different from the conventional model, which was 46.67 g. Whereas if the method converted per ha, the best yields found in the plant factory cultivation model produce caisim vegetables of 27.56 tons/ha, different from the greenhouse planting model is 16.22 tons ha and significantly different from the conventional model which is 7.89 tons/ha.

Abstract

Shallots are one of the important strategies for commodities whose price fluctuation is considered as a commodity that can affect inflation. Therefore, shallot farming is important to note. This study aims to analyze the income and feasibility of shallot farming before and during the Covid-19 pandemic. The research location was determined purposively, with a total sample of 45 people selected based on the census method. Methods of data analysis using farming analysis. The results showed that shallot farming in Torongrejo Village, Junrejo District, Batu City before and during the Covid-19 pandemic provided farmers with an average income of IDR 66,424,807.05 per hectare and IDR 152,732,757.00 per hectare. With this income, shallot farming is feasible to develop based on the R/C value of 3,796 before the Covid-19 pandemic and 6,682 during the Covid-19 pandemic. In addition, the price BEP value was IDR 3,906.92 per kg before the Covid-19 pandemic and IDR 3,741.26 per kg during the Covid-19 pandemic. BEP output was 1,559.63 kg per hectare before the Covid-19 pandemic and 1,075.16 kg per hectare during the Covid-19 pandemic. Thus the Covid-19 pandemic does not harm shallot farming at the research location.

Abstract

Biological control by using entomopathogenic bacteria shows potential to be developed as an alternative technique to control Spodoptera litura. Bacteria that can live in extreme environments are reported to have high efficiency and the ability to survive in various environmental conditions, such as in the area of Sidoarjo mud. Related to the issue, this research aimed to find out bacteria that can survive in extreme conditions and are potentially entomopathogenic to control S. litura. The study was conducted from January until July 2021 in the Sidoarjo mud area and laboratory of Biological Control, Faculty of Agriculture, University of Brawijaya. The research was conducted using methods including consist of a sampling of Sidoarjo hot mud, isolation, and screening of bacteria that is potential as entomopathogenic bacteria, bioassay of mortality S. litura, development of larvae and pupal using Completely Randomized Design with 11 treatments and 4 replications, and molecular identification by 16S rRNA. Data for mortality and development of larvae and pupal were submitted to variance analysis, followed in comparison to the averages of the Duncan test at a 5% level of significance. The results showed that 43 colony bacteria from Sidoarjo hot mud have been successfully isolated and obtained 9 isolates selected as entomopathogenic bacteria against S. litura with a percentage of mortality larvae reached 60%. Moreover, bacteria have the potential to inhibit the development of larvae and pupal S. litura. Molecular identification showed that potential isolates are Bacillus subtilis strain 15A-B92, Bacillus thuringiensis strain GTG-29, and Bacillus anthracis strain BA1035.

Abstract

This study aims to determine whether there is a significant difference in the composting time of teak sawdust and the dose of teak sawdust on the growth and yield of shallots of the lancor blue variety. This research was conducted in Tidu Village, Pohjentrek District, Pasuruan Regency. This study used a factorial randomized block design (RBD) method consisting of two factors repeated three times. The first factor is the composting time (L) with L1: 4 weeks, L2: 6 weeks, and L3: 8 weeks. The second factor was the dose of teak sawdust (M) with doses of M1: 5 tonnes ha-1 , M2: 10 tonnes ha-1 , and M3: 15 tonnes ha1 . Overall there were nine treatment combinations. The results showed that composting time of 8 weeks and sawdust dosage of 15 tonnes ha1 resulted in a dry weight of wind on shallot bulbs of 10.74 tonnes ha-1

Abstract

Mahogany plants have many benefits, one of which is the seeds of the mahogany tree. The content of flavonoids in mahogany seeds is high and used as antioxidants. This study aimed to know antioxidant and flavonoid content of mahogany seed extract.The extraction method used in this study is the maceration method and antioxidant test using the DPPH method. DPPH solution was prepared by dissolving DPPH powder dissolved in ethanol p.a. Antioxidant inhibition test with several variations of concentration and inhibition values, namely 7500 ppm at 76.41%, 3750 ppm at 67.07%, 1875 ppm at 42.54%, 937.5 ppm at 22.13% and 468.75 ppm by 9.95%. The highest inhibition was at a concentration of 7500 ppm with an inhibition value of 76.41% and the lowest at a concentration of 468.75 ppm with an inhibition value of 9.95%. The result showed that mahogany seeds have high antioxidant levels with an IC50 value of 64.07 mg/ml. The content of flavonoids in mahogany seeds showed high levels with a value of 17.7 QE with an extract concentration of 100 ppm.

Abstract

This study aimed to identify and know the associated insects and their role in sweet corn plants. This study used a non-factorial randomized block design (RBD) with three kinds of treatment; yellow traps, net traps, and ground traps. Each treatment was repeated nine times so that there were 27 experimental units. In each treatment plot, the sample size is 3m x 1m. Sampling of insects on corn plants using net traps, yellow traps, and soil traps. The result showed that found 1,012 insects, from 8 Ordo and 25 families in sweet corn plants. In the vegetative phase found 636 insects in various roles. 408 insects are pests and 228 insects that are natural enemies. A total of 406 insects were found in the generative phase, 196 of which were pests and 210 were natural enemies.
