Abstract

ABSTRACT This study aims to determine how the behavior of farmers in the implementation of Integrated Pest Management (IPM) in terms of three aspects: the ecological aspects, economic aspects and technological aspects. This research was conducted in two districts in East Mongondow Bolaang. Collecting data in this study conducted at 40 farmers of the District Parent and Modayak Modayak West. All farmers are farmers who have participated in the Field School of Integrated Pest Management. The data collection is done by using a questionnaire. The questionnaire was prepared based on measurement principles Likert Scale. The collected data were analyzed using Multiple Linear Regression Analysis. Based on the research, regression equation: Y = 4.240 + + 0,326X3 0,083X2 0,07X1 + e. Furthermore, based on the results of testing of the F-statistic can be concluded that the ecological aspects, economic aspects and technological aspects together have the same effect on the opinion of the farmer (Y) significantly. This we can see where the F-count is 8,040 and the F-table for 2866, in other words 8,040 F count> F-Table 2866. So the null hypothesis is rejected. It means ecological aspects, economic aspects and technological aspects together have the same effect on the opinion of the farmer (Y). While based on t-test statistics for independent variables namely the ecological aspects, economic aspects and aspects of the technology are as follows: the ecological aspect t calculate equal to 2,422> t table 2028, the economic aspect t calculate equal to 2,083> t table 2,028 and technological aspects t of 2,702> t table 2,028. Thus, ecological aspects, economic aspects and technological aspects of the real effect on the opinion of farmers about IPM.

Abstract

This study aims to: (1) determine the content of sulforaphane in several types of broccoli sprouts. (2) Knowing the difference in sulforaphane content in the combination of NAA, BAP and types of broccoli grown on MS media; (3) knowing the difference in sulforaphane content in the combination of NAA and types of broccoli sprouts grown on MS media; (4) knowing the difference in sulforaphane content in the combination of BAP and the type of broccoli sprouts grown on MS media. This study used a completely randomized design (CRD) arranged in a factorial manner, namely factor A: NAA 0, 0,5, and 1 ppm. B: BAP 0, 1, 2 ppm and C : 2 Types of Broccoli. The variables observed were: germination time, germination weight, and sulforaphane content. The data were analyzed by analysis of variance and continued with the 5% BNT test. The results showed that germination time began to appear on day 3 and all seeds germinated. Sprout weight varied greatly, and the combination of treatments N1, B0 and BR2 gave the highest average weight and calculated concentration (ENT) of sulforaphane, followed by treatments N0B2BR2 and N0,5B0BR1.

Abstract

This study aims to determine the effect of auxin type and concentration on the growth and development of orchid plants. The research was conducted at the Tissue Culture Biotechnology Laboratory, Faculty of Agriculture, Sam Ratulangi University Manado, and was carried out over 2 months from July to August 2023. This study used a factorial experiment in a Completely Randomized Design (CRD) with 5 replications consisting of two factors. The first factor is the type of auxin: IAA (A1), NAA (A2), and IBA (A3), and the second factor is the concentration of each auxin: 1 ml/l (K1), 2 ml/l (K2), and 3 ml/l (K3). The data were analyzed using analysis of variance, and if the results were significant, a 5% Least Significant Difference (LSD) test was conducted. The results showed that there was an interaction between the type and concentration of auxin on variables such as the number of roots, root length, root emergence time, number of leaves, number of shoots, and shoot height. Similarly, there was an effect of auxin concentration on each type of auxin, but there was a significant effect of individual auxin types (IAA, NAA, and IBA) on the root formation of Dendrobium mirbelianum orchids, affecting variables such as the number of roots, root length, root emergence time, number of leaves, number of shoots, and shoot height.
