Abstract:
[THE EFFECT OF IMMERSION IN GA3 AND SOME KINDS OF TSS ON THE GROWTH OF SHALLOTS (Allium ascalonicum L.)]. Shallots (Allium ascolonicum L.) are very much needed by the community and have become one of the high-value commodities in Indonesia. TSS or True Shallot Seed is an elective that can be created as a wellspring of seeds and is an answer for address the issue for quality shallot seeds. In the utilization of TSS seeds, there are still a few deterrents in low development strength. In the use of TSS seeds, there are still some obstacles in low growth strength. Dormancy can be solved by treatment with growth regulators that can encourage, inhibit or qualitatively alter plant development and advancement. One of the PGRs that is regularly utilized is Gibberellins (GA3). This review meant to get the connection between splashing time with a few TSS seeds on the development of shallots, which included germination, development simultaneously, development speed, germination life, plant length, and the quantity of leaves. This examination was led in Ketindan Town, Lawang Area, Malang Regime, East Java, from February to April 2021. This review was a factorial investigation organized dependent on a Randomized Complete Block Design (RCBD) comprising of 2 factors: the length of inundation and the kind of TSS seeds that were rehashed as much as multiple times. The main variable was the inundation time in a GA3 arrangement with a centralization of 40 ppm comprising of no dousing, 15 minutes, 30 minutes, and 45 minutes of inundation. The seed factor of shallot TSS consists of TSS Sanren, TSS Lokananta, and TSS Bauji. The outcomes showed that the mix of splashing time and TSS seed type fundamentally impacted development speed simultaneously and the quantity of leaves 7 dap.

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:
[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

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:
[JATROPHA SEED POTENTIAL AS A NATURAL RODENTICIDE]. The controlling of rat's pest attacks often use chemical control that adversely affects non-target animals and leaves a residue for the environment. One of the recommended controls is to use natural rodenticides derived from jatropha seeds and do not harm non-target animals that are environmentally friendly. This research aims to determine the interaction and the best combination of bait mixed with jatropha seeds on the death of Mus musculus, as well as the type of bait and the best dose of jatropha seeds on the death of Mus musculus. The design in this study used a completely randomized design consisting of two factors, the first factor was the bait and the second factor was the dose of jatropha seeds. The results showed that there was an interaction between the type of bait and the dose of jatropha seeds on the amount of feed consumed by Mus musculus. The combination of bait type and dose of jatropha seeds that was best for the mortality of Mus musculus was found in the treatment of rice flour with 3.0 g of jatropha seeds, cornflour with 3.0 g of jatropha seeds, and fish meal with 3.0 g of jatropha seeds. The best dose of jatropha seeds in reducing the bodyweight of Mus musculus, accelerating the time of death, and increasing the percentage of death was 3.0 g of jatropha seeds with an average decrease in body weight of Mus musculus reaching 75%, and the fastest death for five days, and able to kill 100% of Mus musculus.

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.
