“…Shoot on the plants is apical meristem tissue which is considered as auxin production. In this part, cell division and magnification are very high, thus pruning around cut area can stimulate auxin translocation around them and stimulate new branches growth as well [5,6]. Another stimulator compounds, for instance, synthesized sucrose and nitrogen compounds within the leaves then move to cut part.…”

Coffee production success in Indonesia was strongly affected by culture technique, for instance, proper pruning. Pruning Arabica coffee seedling is one of techniques to boost productivity by cutting the plant shoots and stems. This study aims to determine the effectiveness of shoot pruning and 50% pruning on the growth of Arabica coffee seedlings. Data processing was carried out by statistical methods to compare or test the average data of two paired populations using the T test at a level of 0.05. Parameters observed were plant height, number of leaves, stem diameter and number of branches. The results of the arabica coffee seedling experiment with two treatments of pruning on the shoots pruning showed that the average plant height, number of leaves, and number of branches, was higher than pruning at the 50% pruning. Meanwhile, pruning 50% of stem diameter showed a higher average than pruning of shoots. It can be concluded that pruning of Arabica coffee seedlings, especially shoot pruning, has a better effect on the growth of arabica coffee seedlings.

“…To prevent the variation in vegetative and productive growth of coffee plants (bienniality), research using plant growth regulators have been increasingly applied (Hatanaka et al, 1991;Cavalcante Filho et al, 2018;Mwaniki et al, 2019;Muliasari et al, 2021). Growth regulators are synthetic or natural chemical compounds that can modulate and regulate the physiological aspects of plants (Ashikari et al, 2005;Pu et al, 2018).…”

Coffee is one of the main agricultural commodities in the world. Thus, research aimed at reducing the productive risks of the crop has been increasingly encouraged, among which the use of plant hormones stands out. In addition, the objective of this work was to analyze the effect of the application of indole-3-acetic acid on the growth, nutrition and gas exchange of young Coffea arabica L plants. The experiment was carried out in the field in the city of Alegre, Espírito Santo, Brazil. The experimental design used was randomized blocks, testing the effect of the application of five doses of indole-3-acetic acid in young Arabica coffee plants, in four replications. The application of indole-3-acetic acid stimulates the growth rate of the stem diameter at a concentration of 60 mg L -1 , as well as gas exchange in coffee plants, however it did not favor the increase in the substomatic concentration of CO2 instantaneous and intrinsic efficiency in water use and instantaneous carboxylation efficiency. Although the application of EIA was not able to provide direct gains in coffee growth during the experimental period, a longer evaluation of the treatments would possibly provide promising results for the coffee crop. The multivariate analysis showed that higher doses of auxin have a high relationship with the macronutrients studied.

“…In short, the two forms of activity place students in campus partner schools and industries for 6 (six) months to carry out integrated learning. However, there are big problems and obstacles in the implementation of the two forms of MBKM activities during this pandemic (Astri Muliasari et al, 2021;Hidayatullah, 2021;Said & Muslimah, 2021;Wiratraman & Lafrance, 2021).…”

The objectives of this research include (1) developing smart expert system innovation integrated hybrid advisory; and (2) Testing the attractiveness and feasibility of the hybrid advisory integrated smart expert system innovation prototype. The method in this research is in the form of research and development (Re-search and Development). Where the method includes a preliminary study; model design; development of model prototypes; model prototype testing; model prototype revision; validated model prototype results; model prototype experimentation; tested models; and dissemination. all state universities in East Java (students,equipped with lecturers, officials in PT and stakeholders). The research instrument used questionnaires, documents, structured surveys, observations, and in-depth interviews. The results of this study include: (1) the innovations developed have synchronous and asynchronous online guidance features, submit reports and daily assignments, student progress reports, live chat with supervisors and instructors, daily attendance, to review report results; and (2) the Smart Expert System Integrated Hybrid Advisory innovation developed has valid results without revision with an average score of 90.1 (user benefit aspect), an average score of 90.5 (application display aspect), an average score of 93 ,8 (newness of information aspect), average score of 97.6 (content aspect), average score of 90.6 (user-friendliness aspect), average score of 93.8 (competency achievement aspect).
