“…Collective readiness reflects the extent to which individual tendencies approve, accept, and adopt innovative technologies and specific plans aimed at changing current conditions. Meanwhile, Lemos et al (2016) stated that external factors in the adoption process in rural areas have a positive contribution to agricultural development, while Larrasquet, Pilnière, and Jayaratna (2016) stated that understanding and principles in the process of technology adoption are urgently needed by adopters. Thus, the dimension of the role of the government, consisting of socialization, training and counselling, was able to provide a change to the perceived farmer card technology.…”

This study aims to test the model adoption of farmer card innovation by farmers. Data were collected through the use of the survey technique. The respondents were obtained through cluster sampling from six districts that included the greatest numbers of farmer card users in central Java. Data analysis was done through the SEM technique. As a result, from the five variables included, reconstruction and merging of the independent variables were then carried out so that three important antecedent variables appeared regarding influencing the adoption of farmer cards, namely leadership, facility conditions, and the role of government mediated by perceptions of card technology. The application of farmer cards produced such a farmer database, accuracy improvement, and government service to farmers. Future research needs to be directed toward carrying out development research related to increasing the capacity of information technology regarding farmer cards; hence it will bring better welfare to farmers. No previous research has explained how small farmers adopt information technology provided by the government. Many events have transpired, but these dynamics have not been revealed in previous research. This research resulted in an adoption model that enriches the previous Rogers’ innovation adoption theory, especially how leadership factors play an important role in the adoption of information technology innovations

“…However, the spread use of avermectins tends to result in consecutive accumulation in food-producing animals and plants 4 , 5 . To detect avermectins (Abamectin B 1 ), various analytical approaches were employed, involving high-performance liquid chromatography-ultraviolet detection (HPLC–UV) 4 , liquid chromatography-tandem mass spectrometry (LC–MS) 6 , high-performance liquid chromatography-fluorescent detector (HPLC-FLD) 7 , enzyme-linked immunosorbent assay (ELISA) 8 and liquid chromatography-tandem mass spectrometry/mass spectrometry (HPLC–MS/MS) 9 . Whereas, in most case, these approaches either needed a time-consuming process, high-cost accurate instrument, and high professional operators, which makes them difficult to apply in general laboratories 10 .…”

The development of detecting residual level of abamectin B1 in apples is of great importance to public health. Herein, we synthesized a octopus-like azobenzene fluorescent probe 1,3,5-tris (5′-[(E)-(p-phenoxyazo) diazenyl)] benzene-1,3-dicarboxylic acid) benzene (TPB) for preliminary detection of abamectin B1 in apples. The TPB molecule has been characterized by ultraviolet–visible absorption spectrometry, 1H-nuclear magnetic resonance, fourier-transform infrared (FT-IR), electrospray ionization mass spectroscopy (ESI-MS) and fluorescent spectra. A proper determination condition was optimized, with limit of detection and limit of quantification of 1.3 µg L−1 and 4.4 μg L−1, respectively. The mechanism of this probe to identify abamectin B1 was illustrated in terms of undergoing aromatic nucleophilic substitution, by comparing fluorescence changes, FT-IR and ESI-MS. Furthermore, a facile quantitative detection of the residual abamectin B1 in apples was achieved. Good reproducibility was present based on relative standard deviation of 2.2%. Six carboxyl recognition sites, three azo groups and unique fluorescence signal towards abamectin B1 of this fluorescent probe demonstrated reasonable sensitivity, specificity and selectivity. The results indicate that the octopus-like azobenzene fluorescent probe can be expected to be reliable for evaluating abamectin B1 in agricultural foods.

Furthermore, a facile quantitative detection of the residual abamectin B1 in apples was achieved. Good reproducibility was shown based on relative standard deviation of 2.20%. Six carboxyl recognition sites, three azo groups and unique fluorescence signal towards abamectin B1 of this fluorescent probe decided ideal sensitivity, specificity and selectivity. The results show that the octopus-like azobenzene fluorescent probe may be promising for evaluating abamectin B1 in agricultural foods.
