Abstract

[TUNGRO DISEASE ON RICE PLANT (Oryza sativa) IN TABA PENANJUNG DISTRICT: DISEASE INCIDENCE AND MOLECULAR DETECTION OF VIRUSES]. Tungro is one of the important diseases of rice plants. Tungro disease caused by Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). This research aims to obtain information on the spread of the disease, vector population, and molecular detection by polymerase chain reaction method. This research was conducted from December 2019 to April 2020 in rice fields in Taba Penanjung sub-district, Bengkulu Tengah district at ± 540 meters above sea level and virus detection in the Laboratory of Biotechnology and Genetics Department of Biology Faculty of Mathematics and Natural Sciences (MIPA) and Laboratory of Plant Protection, Agriculture Faculty, Bengkulu University. Data analysis used descriptive analysis. The results showed that the highest disease incidence on the seven weeks after planting (wap) is 1.7% and the highest population of the vector on the 7 wap with an average of 7.7 vector/100m2 in the village of Taba Penanjung. Detection of viruses with the PCR method with the specific primer DAF/DAR succeeded in amplification of DNA band measuring 1,400 bp. RTSV was not detected by RT- PCR using a specific primer or RTSV. The result of this detection shows that the symptoms of tungro on rice plants in the cultivation of Taba Penanjung district associated with RTBV infection. RTSV unable to detect can be caused by many factors in the detection process, including total RNA extraction, cDNA synthesis, DNA amplification, and DNA visualization of PCR products.

Abstract

[GROWTH AND YIELD OF FOUR VARIETIES OF MUNG BEAN (Vigna radiata L.) IN INTERCROPPING SYSTEM WITH VARIOUS CORN PLANT SPACING]. Efforts to increase the productivity of mung beans (Vigna radiata L.) can be done by implementing an intercropping system and using superior varieties. Corn plants need high nitrogen and mung bean plants can fix nitrogen from the free air so that corn plants can take advantage of the excess nitrogen from mung beans. The purpose of this study was to determine the best mung bean varieties in the intercropping system with a various spacing of maize. The research was conducted in October-December 2018, in Pematang Gubernur village, Muara Bangkahulu, Bengkulu. The experiment in this study used a split-plot design with the main plot spacing of maize that was 60 cm x 30 cm, 90 cm x 30 cm, 120 cm x 30 cm, subplots were mung bean varieties (Vima-1, Vima- 2, Vima-3, and Kutilang) with 3 repetitions. Repeated 3 times, then 36 experimental units were obtained. The results showed that the four varieties of mung beans planted intercropping with a various spacing of maize showed different yield responses. Varieties of Vima-1 and Vima-3 gave the highest seed yields at a maize spacing of 60 cm x 30 cm. The Vima-2 variety was at a spacing of 90 cm x 30 cm, while the Kutilang variety was at 120 cm x 30 cm spacing. The four mung bean varieties were suitable for intercropping with maize with a yield/plot (NYi)> 0.5.

Abstract

[THE EFFECT OF LEMONGRASS (Cymbopogon citratus (DC.) Stapf) LEAVES EXTRACT ON RICE WEEVIL (Sitophilus oryzae L.) REPRODUCTION]. Rice weevil (Sitophilus oryzae) is the most destructive pest of rice. S. oryzae can be controlled with lemongrass (Cymbopogon citratus). C. citratus leaves extract can be used as pests control because it contains potential active compounds. This study aims to determine the effect of the several concentrations of C. citratus extract from fresh and dry leaves on S. oryzae reproduction. This study was used factorial RAL with two factors. The first factor was concentrations which were divided into 5%, 10%, 20%, as well as the positive control group (alfamethrin 1%) and the negative control group (aqua dest). The second factor was the use of C. citratus leaves which were divided into fresh and dry leaves. Parameters observed were the repellent of S. oryzae, the number of new adults, the damaged rice percentage, and the rice organoleptic. The rice organoleptic was conducted to observe color, texture, smell, and taste. The data were analyzed using a two-way ANOVA test. The best result has been found in the concentration of 20% from fresh C. citratus treatment with an average repellency of 68.50±14.45%, the number of new adults of 29±4.99, and the damaged rice percentage of 24.75±4.113%. The result of the organoleptic test with the highest average value was found in the concentration 5% from fresh C. citratus treatment. The results of the organoleptic test with Kruskal-Wallis showed that there were no significant differences in the color, texture, smell, and taste of rice. The conclusion of this study showed that C. citratus can be used effectively against S. oryzae.

Abstract

[EFFECT OF CONCENTRATION AND TIME INTERVAL OF BABANDOTAN BIOPESTICIDE SPRAYING ON THE INTENSITY OF DAMAGE AND YIELD OF KAILAN]. Biopesticides from Ageratum conyzoides plants are used as an alternative in pest control. The used of synthetic pesticides was widespread as an effort in pest and disease control because it worked effectively and quickly, but caused resistance and resurgence of pests were bad impact on the environment for long term. The content of active compounds in Ageratum conyzoides plants such as flavonoids, anthraquinone, tannins, terpenes, phenols, saponins, alkaloids and steroids worked as controllers of various cultivated plant pests. This study aims to determine the spraying concentration and interval of spraying Ageratum conyzoides on the intensity of damage and yield of kailan plants. This research was conducted in November 2020 - January 2021 at Agroecotechnopark research land, Diponegoro University, Semarang. The experimental design used was a factorial Randomized Complete Block Design with 3 replications. The first factor was spraying concentration (10%, 30% and 50%) and the second factor was interval of spraying (once every 5 days, 10 days and 15 days). The variables observed were absolute damage rate, relative damage rate, plant height, number of leaves and fresh weight of kailan. Data were analyzed by Analysis of Variance followed by DMRT (Duncan's Multiple Range Test). The results showed that Ageratum conyzoides biopesticide was able to control pests and and to support kailan growth. Spraying babandotan biopesticide at a concentration of 50% has been able to reduce the rate of crop damage by pests, supported vegetative growth, and increased kailan growth to provide optimal yield. Spraying time interval did not affect all variables.

Abstract

[EFFECT OF PLANTING MEDIA COMPOSITION AND ATONIC GCS ON THE GROWTH OF COCOA SEEDS (Theobroma cacao L.)]. Cocoa (Theobroma cacao L.) is one of the essential crop commodities which is prospective and provides an excellent opportunity to improve community welfare. This study aimed to determine the effect of combination planting media and atonic growth control substances (GCS) on the growth of cocoa seedlings (Theobroma cacao L.). The research was conducted at Jalan Harmonika Baru Pasar 2, Tanjung Sari Medan in March -June 2019. The research was carried out using factorial randomized block design (RBD) with two factors: planting media (manure, ultisol soil, sand) and atonic GCS (0, 1, 2, 3 cc/L water). The first factor is the composition of the growing media in the form of manure, ultisol soil, and sand which consists of 4 fields, namely control, ratio 1:1:1, ratio 1:2:1, and ratio 1: 3:1. The second factor is the dose of atonic GCS application, which consists of 4 levels, namely without atonic GCS application, 1 cc/L, 2 cc/L water, and 3 cc/L water. The results showed that the combination of planting media consisting of manure, ultisol, and sand with a ratio of 1: 3: 1 has a significant effect on increasing plant height, stem diameter, number of leaves, and leaf area of cocoa seedlings. The atonic growth control substances of 3 cc/L water significantly increased plant height, stem diameter, number of leaves, and leaf area of cocoa seeds. The interaction between the growing media composition and the concentration of GCS atonic significantly affected the number of leaves. However, it was not significant for plant height, stem diameter, and leaf area of cocoa seeds. To conclude, the composition of the planting medium and atonic growth control substances significantly affect the growth of cocoa seedlings (Theobroma cacao L.)

Abstract

[ALLELOCHEMICAL POTENTIAL OF AQUEOUS EXTRACT AND MULCH OF PLANT BIOMASS OF SORGHUM (Sorgum bicolor L. Moench)]. This study was aimed to examine the allelopathic potential of sorghum through aqueous extract and mulch from biomass on seed germination and early growth of three tested plants, namely rice, mustard and cucumber. The results showed that the aqueous extract of the sorghum biomass significantly inhibited the germination of mustard and cucumber seeds, reduced the vigor-index of the germination of rice, mustard and cucumber seeds, and suppressed the growth of radicle length of mustard sprouts. The same thing was seen when sorghum biomass was tested as mulch which also suppressed the early growth of the tested plants on the variables of stem height, fresh and dry weight of biomass of rice, mustard and cucumber. The higher the concentration of allelochemicals extract or sorghum mulch, the stronger the inhibition on germination and early growth of the three test plants. At a concentration of 10% allelochemicals suppressed the germination of mustard and cucumber to 76 and 79%, respectively, while a dose of 10% mulch suppressed early growth in the height of rice, mustard, and cucumber to 56, 55, and 68%; and dry weight to 53, 30 and 60%. The results of this study are important information about the allelochemical potential of sorghum as a natural herbicide in integrated weed management
