Abstract
Usage of true shallot seed (TSS) can increase onion production. TSS production in the lowlands is still an obstacle by suboptimal flowering of shallots propagated through seed tubers. There are several varieties of shallots that have not been successfully flowered. The treatments of vernalization and administering GA3 are expected to stimulate the flowering of Bauji variety. The purpose of this study was to improve the flowering of the onion varieties of Bauji in the Jember lowlands (89 m asl). The study was conducted from June to October 2019. The study used a factorial completely randomized block design (CRBD), namely vernalization as the first factor and GA3 concentration as the second factor with four replications. Data were analyzed using analysis of variance and continued with the Duncan Multiple Range Test (DMRT) at a 5% level. The results showed that independently, vernalization had a significant effect on the parameters of the time the umbel appeared, the percentage of flowering plants, and the number of umbles per plant. Also, vernalization treatment had significantly affected the parameters of the number of flowers per umbel, the number of capsules per umbel, and the percentage of capsule formation per umbel.

Abstract
Some organic ingredients are known to contain nutrients and natural plant growth regulators (PGR), such as coconut water, young corn, sprouts, banana weevil, bamboo shoots. These materials are also a substrate for multiplying local microorganisms that are good for the soil. Therefore, the purpose of community service activities in the Exemplary Farmers Group, Sumberjambe Jember is to introduce, improve skills and implement local microorganism fermentation technologies (bio activators) using organic materials that contain natural plant growth regulators. This activity uses direct methods and practices for making natural PGR. The results achieved based on the indicators of the implementation of this training include the response of the attendance of the training participants attended by 30 people or 100% invited to attend the training event. Besides, during the extraction and fermentation activities of organic materials, it was seen that participants knew the sequence of procedures for making Natural PGR from the results of discussions and questions and answers. Also, a quantitative assessment of the success of the briefing activity was carried out through pre-test and post-test. The results obtained in the initial test mean the understanding of natural PGR is 25, while the post-test mean score after implementation is 75. Based on the pre-test and post-test results, there is a significant increase in participants knowledge about organic growth regulators. These results can also indicate that this activity can increase participants knowledge. In practice, about 80% of participants have been able to extract and mix ingredients for the fermentation process. The indicator of success is evident from the well-fermented natural PGR material which is characterized by a brown color and acidic odor resembling fermentation results.

Abstract
Indonesia is an agrarian country where farming is the main occupation of its people. Therefore fertiliser becomes an indispensable item. At present, the majority of fertilisers are met by chemical fertilisers. The low content of micronutrients in chemical fertilisers causes quality degradation to the chemical, physical, and biological properties of the soil. Organic fertiliser is one of the strategic solutions to overcome these problems. Agricultural and livestock waste, including coconut husk, goat manure, and chicken excreta can be used as raw material for liquid organic fertiliser. Experiments were comparing various compositions of coconut husk used, namely 0, 0.65, 1.25, 2.5, and 5%. The analysis design used is One-Way Anova. Fermentation was carried out for one week in anaerobic conditions. Ammonium, nitrate, and nitrite levels of bioculture with the addition of 5% young coconut husk were significantly higher than other treatments, obtained values, 0.193; 0.705; and 0.523%, respectively. The bioculture made has met the quality of liquid fertiliser as in Standar Nasional Indonesia (SNI).

Abstract
As a raw material for the food industry, spinach quality standards are considered both physical and chemical quality, including the nitrate contains. Nitrates that are consumed by humans will be very dangerous because can cause methaemoglobinemia. The nitrate content in spinach comes from the chemical nitrogen fertilizer used, while Azolla compost contains a lot of nitrogen, so the use of Azolla compost can replace nitrogen fertilizer and reduce the nitrate content of spinach. This study aims to determine the effect of Azolla liquid organic fertilizer concentration and nitrogen fertilizer on the growth, yield and quality of spinach, in order to obtain high quality spinach production both physically and chemically. The research used factorial randomized block design, Factor I: Azolla Liquid Organic Fertilizer (LOF) consisting of: A0 = No LOF, A1 = LOF 10 m/liter, A2 = LOF 20 ml/liter. Factor II: Urea fertilizer dosage of: U1 = Urea 50 kg/ha, U2 = Urea 100 kg/ha, U3 = Urea 150 kg/ha, U4 = Urea 200 kg/ha. The parameters observed were: 1) Plant height, 2) Number of leaves, 3) wet weight, 4) dry weight, 5) Plant weight, 6) Soil Analysis, 7) Analysis of Nitrate, 8) Analysis of Protein

Abstract
Prancak 95 tobacco has the potential to be developed in Indonesia because it has a distinctive aroma and a nicotine content of 2.13%. The quality of this tobacco raw material must be improved and started from the use of quality seeds through in vitro culture techniques. However, several things that must be considered are the acclimatization stages. One of the efforts to increase the growth of seedlings during the acclimation can be done by providing natural plant growth regulators (PGR) from extracts of organic materials such as coconut water, young corn, sprouts, and banana weevil that has been fermented in advance using EM-4 bioactivators . Based on this, the purpose of this study was to determine the optimal concentration of natural growth regulators in the acclimatization of Prancak -95 tobacco. This study uses a non factorial randomized block design with four treatments concentrated solution of natural growth regulators, which include: Control (no treatment), 10; 25; and 50 ml/L. The observed variables included the number of leaves, leaf area, plant height, and root length. Data analysis using ANOVA Test and continued with DMRT Test at 95% confidence level to find out the best treatment. Based on the results of research that has been carried out for 60 days of observation, it can be concluded that the application of natural PGR is able to spur the growth of seedlings during the acclimatization period. Spraying application at a concentration of 10 ml / L can increase the number of leaves, leaf area, number of roots and height of Prancak 95 tobacco seedlings.

Abstract
Rhizobium is one of the important microorganisms in free nitrogen fixation. The study aims to determine the use of Rhizobium spp as substitute for chemical fertilizer Nitrogen on soybean cultivation. The study was conducted in the village of Sukorejo, Bangsalsari Subdistrict, Jember Regency from May to August 2019. The experiment design was a randomized complete block with four replications, using Rhizobium isolate in granule and powder media with spraying volume 600cc/kg granules and 400cc/kg of powder. The composition of the granules and powder media consists of edamame soybean waste, zeolite, phosphatealam, kaptan and tapioca. Rhizobium isolates were obtained from Protection Laboratory of Politeknik Negeri Jember. The treatment dosage consisted of 3 g; 4 g; 5g and 6 g/plant, while the control was Phonska fertilizer 1,5 g/plant (180 kg/ha equivalent). Research data were analyzed by Anova and Dunnet test. The results showed that 1) The use of rhizobium granules and powder as much as 4.0 g / plant was not significantly different in the formation of root nodules compared with 1.5 g / plant fertilization at 56 DAP and 70 DAP; 2) Number of root nodules 56 DAP with 4 g/plant was 23.66 (granules), 23.25 (powder) and 20.60 (control); 3) The number of 70 DAP root nodules with granular fertilizer and powder of 4 g/plant respectively was 24.20; 23.96; and control 22.90; 4) The use of Rhizobium in granule media 6 g/plant for the number of pods did not show a significant difference compared to controls (180 kg Phonska/ha); 5) The use of granules of 4 g - 6 g/plant produced significantly different seed weights compared to controls, namely 13.67 g and 13.95 g. The use of Rhizobium isolates 600cc/kg granules and 400cc/kg of powder applied to 4-6 g/plant can be used to replace the use of chemical fertilizer Nitrogen Phonska as much as 180 kg/ha in soybean cultivation.
