This study aims to determine the concentration of nutrients AB mix liquid biological fertilizer combination will affect the growth and production of three varieties of mustard hydroponic DFT system. This research was conducted at Bedadung Indah AA8 Housing, Jl. Teuku Umar, Tegal Besar Village, Kaliwates District, Jember Regency, which will be held from January 1, 2022 to February 23, 2022 at an altitude of ±89 meters above sea level. This research was conducted using a factorial 2 x 3 Completely Randomized Design (CRD) with 5 replications. The first factor is nutrition (N) consisting of two levels of treatment, nutrient concentration AB mix 1000 ppm (N1) and nutrient concentration AB mix 1000 ppm combination of liquid biological fertilizer 2 ml/lt water (N2). The second factor was variety (V) which consisted of three levels of treatment, Pagoda mustard (V1), mustard green (V2) and mustard kailan (V3). The data obtained were then analyzed by uij F using the help of IBM SPSS Statistic 26 software for Windows, the significantly different results were further tested with Duncan at a level of 0.05. The results showed that the nutrient concentration of AB mix 1000 ppm with a combination of 2 ml/lt water (N2) liquid biological fertilizer gave the best response to the number of leaves and the fresh weight of mustard greens.. The interaction of nutrient concentration of AB mix and its combination with liquid biological fertilizer (N) and variety treatment (V) was not significantly different on the growth and production of three hydroponic mustard varieties using the DFT system.

This research is a qualitative descriptive research carried out at the Experimental Garden in Pancakarya Village, Ajung District, Jember Regency with a height ranging from 50 meters above sea level. To describe and find out the facts or events that will be examined or research conducted to make it easier for researchers to obtain objective data. This research used 27 honey gourd plants cultivated by Siti Masruroh's sister. Observations were made from June to August 2022. Observations were made using variables that were analyzed descriptively, namely: the number of branching, the appearance of male and female flowers, the presence of flowers and fruits in the plant structure, the percentage of flowers turning into fruit, the percentage of fruit until harvest. Observations were made when the honey gourd plants entered the generative phase, around 18 days after planting until harvest. Supporting observations were carried out on types of pests and diseases, as well as pearl NPK fertilizer analysis. The results of the study stated that the composition of NPK 1:2:3 (K3) had a good effect on the number of branches, the appearance of male and female flowers, the presence of fruit in plant structure, and the percentage of flowers turning into fruit. And the pattern of generative growth of honey gourd with various compositions of NPK fertilizer produces optimal results and is in line with the success of vegetative propagation of honey gourd seedlings.

Hybrid honey gourd is an exclusive commodity because of its fruit shape, appearance, nutritional content, benefits and also the high price. Cultivation of hybrid honey gourd is not too difficult, one of the problems is the procurement of expensive seeds. This can be overcome by vegetative propagation using adventitious shoots which are usually removed. In research, innovations emerged to stimulate adventitious shoots to be successfully developed for vegetative propagation. This study aims to obtain a hybrid honey pumpkin vegetative propagation method, to describe the growth and development of honey pumpkin seeds from vegetative propagation. The design used was a factorial 3x3 randomized block design (RAK) with 3 replications. The first factor is the internode position of the shoot (D) which consists of three segments (D1); four segments(D2); five segments (D3). The second factor is a stimulant (S) consisting of 6 grams of pearl NPK fertilizer per one liter of water combined with 1.5 ml atonic atonic (S1); 3 ml (S2); 4.5 ml (S3). In total there were 9 treatments, namely D1S1, D1S2, D1S3, D2S1, D2S2, D2S3, D3S1, D3S2, D3S3. The collected data were analyzed by analysis of variance and F-test if significantly different, followed by the DMRT 5% test. Inter-unit parameters in one individual (section length) were analyzed by student's t-test.

The aim of the study was to determine the content of bioactive compounds in soursop leaf bioinsecticides and their effect on the diversity of arthropods in rice. This research began from July to October 2022 at the Plant Protection Laboratory and Bioscience Laboratory of the Jember State Polytechnic and Rice Cultivation Land in Balung Lor Village, Balung District, Jember Regency. Arthropod samples were observed visually using Sweep Net Trap, Yellow Pan Trap, Sticky Trap and Pitfall Trap. The GCMS test results detected 29 compounds in soursop leaves. The highest compounds as repellent and antifeedant detected were palmitic acid, oleic acid and acetic acid at 18.39%, 17.40%, 13.83%. The result of probit analysis of LC95 toxicity was 28.92%. The number of individuals in the bioinsecticide treatment was 2036 individuals, 32 species consisting of: 10 herbivores, 13 predators, 3 parasitoids, 4 pollinators, and 3 detrivores. Fipronil numbered 1198 individuals, 26 species consisting of: 10 herbivores, 10 predators, 2 parasitoids, 3 pollinators, and 1 detrivore. Diversity index (H`) shows moderate category in both treatments, dominance index (C`) does not show dominance in both treatments, species richness index (R) in both treatments is moderate, species evenness index (E) is evenly distributed in both treatments and Sorensen The Similarity Index (ISS) is classified as the same with a value of 89.66%. The yield of dry grain in the soursop leaf bioinsecticide treatment was higher (38.25 g per clump) than Fipronil 33.29 gr per clump.

This study aims to determine the mole dosage of soybean stew and the 3 best varieties for the growth and production of mustard greens. This research was conducted in Krajan Hamlet, Sukorambi Village, Sukorambi District, Jember, East Java. from November 2022 to January 2023. The study was conducted using a factorial pattern with a randomized block design (RBD) consisting of 2 factors and 3 replications. The first factor is the fertilization dose treatment (D), which consists of 5 levels, namely (control) D0= 0 m1/1, D1= 25 m1/1, D2= 50 m1/1, D3= 75 m1/1, D4= 100 m1/1 1, and the second factor was 3 different mustard varieties (V) which consisted of 3 levels, namely V1= caisim green mustard, V2= pakcoy mustard, V3= chicory. Parameters observed were number of leaves, plant height, leaf width, leaf length, fresh weight, and root length. The collected data were analyzed by means of variance (Anova), if significantly different it was continued with Duncan's test at the 5% level using Microsoft Excel. The results showed that the mole dose treatment of soybean stew showed no significant difference and the treatment of 3 different varieties showed significantly different results on plant height and fresh weight parameters.

The purpose of this study was to examine the effect of the application of photosynthetic bacteria with chemical fertilizers on the productivity of cayenne pepper. The research was conducted in Pancakarya Village, Ajung District, Jember Regency from September to December 2022 with an altitude of 50 meters above sea level. This study used a non factoria randomized block design (RAK) with six treatments and four replications for a total of twenty four plants. The treatments observed were P0 = control; P1 = 5 ml/L PSB; P2 = 5 ml/L PSB and 2 g NPKCaMg fertilizers (16:16;16:6:0,5); P3 = 5 ml/L PSB and 2 g NPKSCaMg fertilizers (20:4:4:18:1:1); P4 = 5 ml/L PSB and 2 g NPKSCaMg fertilizers (17:12:12:6:4:2); P5 = 5 ml/L PSB and 2 g NPKSCaMg fertilizers (20:30:23:2:3:2). The results showed that the administration of a single application of photosynthetic bacteria did not have a significant effect on all observed parameters. The application of 5 ml/L PSB and 2 g NPKSCaMg fertilizers (20:4:4:18:1:1) had the best effect on stem diameter (7,63 mm), fruit weight planted (52,7 g) and number of fruit planted (25,5 fruit). Give a significant effect on the increase in fruit diameter (12,2 mm) from the control plant (8,1 mm).
