Abstract

Robusta coffee (Coffea canephora) is Indonesia's essential leading trade commodity. Robusta coffee is preferred for its bitter taste. However, robusta coffee productivity decreased due to bad agriculture practice. Tissue culture is an alternative to cultivation with various advantages. The plant growth regulators (PGRs) influence tissue culture’s success. Due to its stability, 2,4 dichlorophenoxyacetic acid has become a common synthetic PGRs. PGRs can be obtained from natural ingredients, such as tomatoes. This study aimed to analyze the effect of 2,4-dichlorophenoxyacetic acid and tomato extract addition and its appropriate concentration for callus induction of robusta coffee in vitro. This research was conducted at the Tissue Culture Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Hasanuddin University. This study used a Complete Randomized Design with two factors. The first factor was the concentration of tomato extract (0%; 7.5%; 10%; and 12.5%). Meanwhile, the second factor was the concentration of 2,4 dichlorophenoxyacetic acid (0 ppm; 1 ppm; 2 ppm; and 3 ppm). Observation parameters include the percentage of callus formation, callus growing time, callus fresh weight, callus color, and callus texture. The quantitative data were analyzed by the Kruskal-Wallis test followed by the Mann-Whitney Test to compare the effect of each treatment. The results showed that among other treatment combinations, treatment with the addition of 2 ppm 2,4-D and 10% tomato extract (T2D2) and treatment with the addition of 3 ppm 2,4-D and 10% tomato extract (T2D3) had the best effect in inducing the callus of robusta coffee.

Abstract

Writing scientific work is an important indicator of the development of knowledge and critical thinking. But still, many teachers have difficulty writing scientific papers, including avoiding plagiarism. The dedication to the society conducted by the Bacharuddin Institute of Technology team Jusuf Habibie aims to improve the skills of teachers at 2 Parepare State High School in reducing the risk of plagiarism in the writing of scientific works through optimization of the use of QuillBot and implementation of paraphrase techniques in writing. The method used is ABCD (asset-based community development). The activities include identification of needs, planning based on problem analysis, preparation of training material books, training on paraphrase techniques and QuillBot, and evaluation of writing quality as well as the effectiveness of training by participants. The training was held on June 6, 2024, followed by 26 participants. The average pretest for the Similarity Index (SI) writing percentage of participants was 54.62%, while the average posttest value for the participant's SI writing percent was 37.85%, with an average SI decrease of 16.77%, showing this training has proven to be effective in reducing the rate of plagiarism among participants. A total of 21 of the 26 participants, or 80.8% of the participants, succeeded in reducing the level of plagiarism in their writings. Thus, this dedication program succeeds in helping teachers improve their skills in writing scientific papers to avoid plagiarism.
