Abstract

Probolinggo Regency has a low literacy rate (78.09%) which is below the average of the East Java Province (88.34%). This data is supported by the recapitulation results of the Directorate of Literacy and Equality Education in 2014 which states that the illiteracy rate in Probolinggo Regency is 64.163 people. Meanwhile, this regency is considered having a high potential in the field of fisheries through catfish farming, located in Sumberasih District. This article discusses the results of the dissemination of illiteracy eradication using instructional book of catfish cultivation. The empowerment method implemented was Empowerment and Development. The instruments used were interview, observation, document, questionnaire, and test. On trial phase, a mentoring was done to the learning community that was called WB. Prior to the mentoring session, pretest was implemented then posttest afterwards which were all done to the WB. Results show that there was an improvement on class average grade, previously it was 58,5 subsequently after the use of illiteracy eradication book, the average grade has improved to 79. The responses gathered from the WB towards the instructional book were very positive. Thus, instructional book of catfish cultivation can be used as a textbook in illiteracy tutorial in minapolitan area.

Abstract

Acehnese Patchouli var. Sidikalang can produce patchouli oil, one of the country's sources of foreign exchange, and it is advantageous in many industries. However, patchouli alcohol (PA) content in patchouli oil is still low. The higher PA content determines the better quality of patchouli oil. So, delignification with Trichoderma viride was carried out to increase PA and yield of patchouli oil. The duration of delignification patchouli leaves is one factor affecting the increase in PA and yield. This study aimed to determine the effect of delignification duration on PA content and yield. The research method was completely randomized with 8 treatments (a combination of 2 treatments: with and without delignification, and 4 delignification durations: 0, 3, 6, and 9 days). The inoculum used for delignification was an inoculum ball, and then patchouli leaf samples were extracted using microwave-assisted extraction (MAE). Gas chromatography was carried out for PA analysis. Delignification of patchouli leaves, with a delignification time of 9 days, showed high PA and yield, which were (0.3129 ± 0.1557)% and (1.4543 ± 0.7717)%, respectively. The success of delignification at  9 days was also shown by increased phenolic content. Trichoderma viride is often utilized in delignification process, but the optimal duration of its delignification of Aceh patchouli leaves that can help improve patchouli oil quality is not yet known. This research is hoped to help related industries improve the secondary metabolites of plants, which has many benefits for the community. Implication/benefit for science development/society.
