Counseling is a process of education outside the school which is systematically organized aimed at adults (the community) so that they are willing, able and self-sufficient in improving or improving the welfare of their families and the wider community. The concept of counseling that will be taken is interest as the participation of a person (farmer) or community group in the development process both in the form of statements and in the form of activities by providing input of thought, energy, time, expertise, capital or material, as well as participating in and enjoying the results. development results. With the negative impact of pesticides, alternative technologies are needed to increase safer agricultural production, namely the use of Plant Growth Promoting Rhizobacteria (PGPR). The analysis used in this thesis research is to use descriptive analysis, the level of interest of chilli farmers in the application of PGPR is analyzed by means of tabulating the data then the average value of the total questions on each indicator item. The assessment of the question is obtained based on the respondent's answer. Then using Simple Regression analysis is a linear relationship between one independent variable (X) and the dependent variable (Y). Then by using Kendall's W Analysis, which is devising a strategy to increase the change in the behavior of chilli farmers' interest in implementing PGPR from the lowest to the highest.

Plant growth-promoting rhizobacteria with multiple growth-promoting traits play a significant role in soil to improve soil health, crop growth and yield. Recent research studies have focused on the integration of organic amendments with plant growth-promoting rhizobacteria (PGPR) to enhance soil fertility and reduce the hazardous effects of chemical fertilizers. This study aims to evaluate the integrated application of biochar, compost, fruit and vegetable waste, and Bacillus subtilis (SMBL 1) to soil in sole application and in combined form. The study comprises eight treatments—four treatments without inoculation and four treatments with SMBL 1 inoculation in a completely randomized design (CRD), under factorial settings with four replications. The results indicate that the integrated treatments significantly improved okra growth and yield compared with sole applications. The integration of SMBL 1 with biochar showed significant improvements in plant height, root length, leaf chlorophyll a and b, leaf relative water content, fruit weight, diameter and length by 29, 29, 50, 53.3, 4.3, 44.7 and 40.4%, respectively, compared with control. Similarly, fruit N, P and K contents were improved by 33, 52.7 and 25.6% and Fe and Zn in shoot were 37.1 and 35.6%, respectively, compared with control. The results of this study reveal that the integration of SMBL 1 with organic amendments is an effective approach to the sustainable production of okra.

Global climate change is leading to a series of frequent onset of environmental stresses such as prolonged drought periods, dynamic precipitation patterns, heat stress, and cold stress on plants and commercial crops. The increasing severity of such stresses is not only making agriculture and related economic sector vulnerable but also negatively influences plant diversity patterns. The global temperature of planet Earth has risen to 1.1°C since the last 19th century. An increase in surface temperature leads to an increase in soil temperature which ultimately reduces water content in the soil, thereby, reducing crop growth and yield. Moreover, this situation is becoming more intense for agricultural practices in arid and semi-arid regions. To overcome climatically induced stresses, acclimatization of plant species via bioinoculation with Plant Growth Promoting Rhizobacteria (PGPR) is becoming an effective approach. The PGPR are capable of colonizing rhizosphere (exophytes) as well as plant organs (endophytes), where they trigger an accumulation of osmolytes for osmoregulation or improving gene expression of heat or cold stress proteins, or by signaling the synthesis of phytohormones, metabolites, proteins, and antioxidants to scavenge reactive oxygen species. Thus, PGPR exhibiting multiple plant growth-promoting traits can be employed via bioinoculants to improve the plant’s tolerance against unfavorable stress conditions.

Bawang dayak is the important medicinal plant that need to be developed in cultivation techniques and production. The use of Plant Growth Promoting Rhizobacteria (PGPR) recently known to be effective to increase plant growth and yield. The research aimed to determine the optimal concentration and immersion time of PGPR on the growth and yield of bawang dayak. The experiment was arrange in complete randomized block design (RCBD) consisting of two factors. The first factor is the concentration of PGPR with 4 levels namely K0 = 0 g L-1, K1 = 5 g L-1, K2 = 10 g L-1 and K3 = 15 g L-1.  The second factor is immersion time of seed, namely P1 = 10 minutes, P2 = 20 minutes, P3 = 30 minutes and P4 = 40 minutes.  The results showed that there was an interaction between concentration and immersion time of PGPR giving effect to the number of leaves and the number of tillers. The immersion time of PGPR for 10 minutes with a concentration of 15 g L-1produced the highest number of leaves (58 leaves) and produced the highest number of tillers (27.67 tillers).  The treatment of PGPR concentration or immersion time of PGPR singly did not affect all observed variables of growth and yield of bawang dayak.
