Abstract

Hydroponic cultivation is an alternative choice for people who plant various types of plants that can be consumed by themselves every day. In addition, hydroponics is one way to grow crops on a large scale without requiring land that is very suitable for cultivation in urban areas. However, this system has several drawbacks, namely, hydroponics really requires a controlled environment, such as monitoring the degree of water acidity, water temperature, and water nutrient density. It needs to be monitored and controlled to avoid a decrease in plant quality. Several ways can be done by using manual measuring tools which actually take time if the hydroponic system is on a large scale, the alternative is to use an Android-based control and monitoring system. This study aims to examine the effect of the best AB Mix nutrient concentration on the growth and production of Sawi Pagoda with the NFT hydroponic system and to control pH, temperature, humidity and nutrients automatically using the Ardiuno Uno sensor. This research was conducted at Rootop PS. Plantation Cultivation from August to October 2020. The design used was a completely randomized design consisting of one factor, namely the concentration of AB mix nutrients consisting of 2 levels: A1: 1000 ppm: 1200 ppm: 1400 ppm (given according to the age of the plant per / week) and A2: 1100 ppm: 1300 ppm: 1500 ppm (given according to plant age per / week). The research was repeated as many as 20 replications so that there were 40 experimental units. The results showed that the A1 treatment level with the concentration of AB Mix nutrient solution (1000 ppm: 1200 ppm: 1400 ppm) was the best treatment level for the increase in plant height and number of leaves on the 2nd and 3rd week and the final plant weight. The hydroponic Nutrient Film Technique system can be monitored and controlled automatically by Arduino, making it easier to control temperature, humidity, ppm of nutrients, and nutrient pH.

Abstract

The use of insecticides is often unavoidable in the production of vegetable crops, but on the other hand it can lead to the presence of harmful substances in vegetables. In this regard, the aims of this study is to determine the relation of Insecticides active substance i.e fipronil toward the reduction of Vitamin C in Hyperaccumulator vegetable i.e Spinach (amaranthus hybridus), Caisim (Brassica juncea) and Kangkung (ipomea raptans) with ex pose facto method, and the samples taken by Completly Random Design (CDR) and tested in Laboratory. The regression test results show the sig value of 0.07> 0.05, the R square value of 0.871 means that it has a significant correlation with the percentage of the correlation of 87.10% on the decrease in vitamin C in vegetables. Vitamin C acts as an antioxidant to ward off free radicals. Insecticide Active Substances made the contains of vitamin in hyperaccumulator vegetable tissue being decrease. Based on the research conducted, it was concluded that there was a negative relationship between the residue of the active substance of the insecticide fipronil and a decrease in vitamin C in hyperaccumulator vegetables, in other words, when the residue of the active substance of the insecticide fipronil increased, the vitamin C content in the vegetables decreased.

Abstract

Seed germination in ultisol is a problem. Ultisol has a low pH, poor in nutrients and organic matter, and high Al content. The low physiological quality of seeds is also a limiting factor. The purpose of this study was to determine the effect of priming on the seed vigor of two chili varieties whose seeds have expired and have not expired. This experiment consisted of 2 experiments, namely Experiment 1, which used seeds that had expired (deteriorating), and Experiment II, which used seeds that had not expired (non-deteriorating). This study was structured using a completely randomized design (CRD) which was repeated three times. This experiment is factorial. The first factor is priming, consisting of five levels: control, immersion in water, 30% PEG, 50 ppm GA3, and 1% KNO3. At the same time, the second factor in the first experiment was the seeds of the Tanjung 2 and Kencana varieties that had expired (deteriorating). In the second experiment, the second factor was the seeds of the Tanjung 2 and Kencana varieties that had not expired (non-deteriorating). The data obtained were analyzed using the R statistic program with a 5% HSD test. The results showed that priming with 50 ppm GA3 and 1% KNO3 increased the vigor of seeds that had expired (deteriorating). Meanwhile, priming with water and 1% KNO3 increased the vigor of seeds that had not yet expired (deterioration). The Kencana variety has a higher vigor than the Tanjung 2 variety on expired seeds. In seeds that have not yet expired, both varieties have the same good vigor.

Abstract

Recent co-evolutionary studies of insect-pathogens have shown that entomopathogenic fungi have a greater potential for oral toxicity in terms of virulence in the mouth infection of insect pests. Therefore, it is necessary to conduct research on finding the route of infection of B. bassiana and M. anisopliae through the mouth in the larvae of the rhinoceros beetle O. rhinoceros. The purpose of this study was to analyze the path of infection of B. bassiana and M. anisopliae in O. rhinoceros larvae through exposure to the entompotagen fungus. The study was conducted at the Plant Protection Laboratory Politeknik Negeri Jember using a single factor Completely Randomized Design (CRD) with B. bassiana and M. anisopliae isolates from Temanggung, Jember and Jombang. Data analysis used Analysis of Variance and further analysis used Least Significant Difference Test at 5% level. The results showed that all isolates were able to infect and cause mortality in the test insects. MJb isolate had the highest effectiveness with the mortality rate of the test insects reaching 100% and the highest spore density with an average of 8.9 x 109 conidia/ml on day 6 after application. The hyphae that were abundant in the abdomen of cadaveric infected with M. anisopliae were different from the hyphae which grew more on the head of insects infected with B. bassiana, confirming previous research on the route of B. bassiana infection through oral toxicity. These results will be useful in providing new information regarding potential pathways of infection of B. bassiana in O. rhinoceros larvae through oral toxicity mechanisms, which until now have been very little reported.

Abstract

TG4 and SR2 were isolates of indigenous bacteria from cassava roots from Banyumas Regency, Central Java. Both are local isolates from marginal lands that can be developed as biofertilizers. This study aimed to determine the potential characteristics of bacterial isolates TG4 and SR2 in supporting the growth of superior upland rice and determining species identity based on the molecular analysis of 16S rRNA. Bacterial isolates TG4 and SR2 were determined for their potency of Plant Growth Promoting Rhizobacteria (PGPR) by fixing N2, dissolving phosphate, and producing Indole Acetic acid (IAA). Bioassays were carried out on TG4 and SR2 isolates by application of bacterial isolates (B0 = control, B1 = TG4, B2 = isolates SR2, B3 = isolates TG4 and SR2) on superior upland rice (V1 = INPAGO UNSOED 1, V2 = UNSOED PARIMAS, V3 = INPAGO 8) in sterile ultisol soil. The F test was used for bioassay data analysis, and if there was a significant difference, it was further tested with Duncan's Multiple Range Test (DMRT) with an error rate of 5%. The identity of bacterial species TG4 and SR2 was obtained by analyzing 16S rRNA sequences and genetic relationships through phylogenetic trees. The results showed that the isolates of TG4 were phosphate solubilizing bacteria and producers of IAA, while the isolates of SR2 were nitrogen fixing, phosphate solubilizing, and IAA producers. The application of bacterial isolates TG4 and SR2 significantly affected root length wet and dry weight of upland rice plants, with the highest value obtained from using a consortium of TG4 and SR2 bacteria. Bacterial isolates TG4 were identified as Bacillus albus, while SR2 as B. Paramycoides. Bacterial isolates TG4 and SR2 can be used as biofertilizers to support superior upland rice growth.

Abstract

Innovation is an important aspect in the nation's competitiveness. Technology transfer is required to bring invention into innovation. However, the implementation technology transfer, especially commercialization technology is still considerably low. This challenge is faced by Indonesian Agency for Agricultural Research and Development (IAARD) to commercialize Indonesian rice varieties. Adoption and interest of Industry in the commercialization of varieties invented by IAARD in 2019 was only 11%. This study aims to build roadmap business strategy for commercialization rice varieties invented by IAARD. The method used in this research was a business model canvas approach, SWOT analysis, and a strategic roadmap. The results showed that there were 11 strategies that can be applied in four approaches , namely a) intensive strategy: expanding and mapping new customer segmentation, optimizing promotion mechanisms and attracting new partners, and strengthening the organizational structure of implementing technology transfer, b) turn-around strategy: adding and increasing HR competence, planning R&D activities by measuring Technology Readiness Level (TRL or TKT), and increasing the capacity of facilities and infrastructure, c) diversification strategy: improving the quality of rice varieties and commercial technology transfer services, pre-licensing, and d) consolidation strategy: building information systems, collaborative alliances with stakeholders, and valuation of intangible assets. The strategies were described in 19 programs mapped on a strategy roadmap of transfer of technology on commercialization rice variety invented by IAARD.
