Abstract

The success of education is greatly influenced by the role of teachers, not only as educators but also as professionals who continuously improve their competencies through reflection and research, one of which is through Classroom Action Research (CAR). This CAR is conducted by teachers to improve the quality of learning and solve problems in the classroom. Despite its importance, many teachers still experience difficulties in writing CAR articles, mainly due to a lack of training in scientific writing. Therefore, this workshop was held to improve academic skills and encourage active participation in scientific writing. This workshop was held offline with 10 teachers. The activity included four main stages: initial planning, socialization, presentation of material by resource persons, discussion and question and answer sessions, and evaluation through post-tests and participant testimonials. The results showed that this workshop was effective in improving teachers' understanding and skills in writing CAR articles.

Abstract

Efficacy wood vinegar produced from wood laban (Vitex pubescens) against Ophiostoma piliferum fungus was evaluated. The objectives of this research to perform in vitro antifungal of wood vinegar from laban wood against O. piliferum. The source of lignocelluloses biomass was carbonization process used three temperature i.e. 350, 400 and 450 °C.  Efficacy of wood vinegar to the fungus carried on PDA (potato dextrose agar) in a Petri dish that has been mixed with the wood vinegar with a concentration of 0, 0.5, 1.0, 1.5, and 2.0 % (v/v). Antifungal test was a factorial 3 by 5 in a completely randomized design. The means were seperated using using Tukey’s test at p = 0.05. All data were analyzed using the SAS softwere (version 8.2, SAS Institute Inc., NC. USA). The test results showed that the pyrolysis suhue effect and concentration of wood vinegar on the inhibition of fungal growth. The higher pyrolysis temperature and concentration the inhibition of fungal growth was increased.Efikasi asap cair dari kayu laban (Vitex pubescens)terhadap Ophiostoma piliferum telah dilakukan.Penelitian ini bertujuan mengevaluasi kemampuan asap cair sebagai antijamur (O. piliferum) secara in vitro. Asap cair yang digunakan diperoleh dengan cara pirolisis pada suhu produksi asap cair dan konsentrasi asap cair yang berbeda. Efikasi asap cair terhadap jamur dilakukan pada media PDA (potato dextrose agar) dalam cawan Petri dengan campuran asap cair pada konsentrasi 0, 0,5, 1,5, dan 2,0 (v/v).Pengujian aktivitas antijamur dilakukan menggunakan rancangan acak lengkap tipe faktorial.Data yang diperoleh dianalisis dengan sidik ragam.Pengaruh  antarperlakuan dilakukan uji BNJ pada taraf nyata 5%. Analisis data menggunakan SAS versi 9.13. Hasil pengujian menunjukkan bahwa suhu pirolisis produksi asap cair dan konsentrasi asap cair berpengaruh terhadap daya penghambatan pertumbuhan jamur. Makin tinggi suhu pirolisis produksi asap cair dan konsentrasinya dan makin tinggi daya penghambatan terhadap pertumbuhan jamur, O. piliferum.

Abstract

AbstractEfforts to overcome wood damage caused by wood decay fungi generally use synthetic fungicides that contain chemical substances that are difficult to degrade in nature. Efforts to reduce acacia wood waste by utilizing acacia bark and twigs as liquid smoke materials. This study aims to evaluate the effect of liquid smoke of bark and acacia twigs with different concentrations on the growth of Shizophyllum commune fungi and determine the optimal concentration of liquid smoke that can inhibit the growth of S.commune. The method used is a Factorial pattern Complete Random Design (RAL) experimental design. The results of the study showed that the liquid smoke of bark and acacia branches had the potential for the growth of S. commune fungus, this was seen from the inability of the fungus to grow on PDA media that had been treated with liquid smoke concentration. The optimal concentration of acacia bark liquid smoke is a concentration of 3% has an Anti Fungal Activity (AFA) value of 100%, but in contrast to acacia branch liquid smoke, the optimal concentration is 4.5% with an AFA value of 75.63% is included in the very strong category. The level of fungal activity is very strong when the AFA value is 75%.Keywords: Anti Fungal Activity (AFA), Liquid Smoke, Schizopyllum commune  AbstrakUsaha untuk mengatasi kerusakan kayu yang disebabkan oleh jamur pelapuk kayu pada umumnya menggunakan fungisida sintesis yang mengandung zat-zat kimia yang sulit terdegradasi di alam. Upaya mengurangi limbah kayu akasia dengan memanfaatkan kulit dan ranting akasia sebagai bahan pembutan asap cair. Penelitian ini bertujuan untuk mengevaluasi pengaruh asap cair kulit kayu dan ranting akasia dengan konsentrasi yang berbeda terhadap pertumbuhan jamur Shizophyllum commune dan  menentukan konsentrasi optimal asap cair yang dapat menghambat terhadap pertumbuhan S.commune. Metode yang digunakan ialah rancangan percobaan Rancangan Acak  Lengkap (RAL) pola Faktorial. Hasil penelitian menunjukan bahwa asap cair kulit kayu dan ranting akasia memiliki potensi terhadap pertumbuhan jamur S. commune, hal tersebut dilihat dari ketidakmampuan jamur untuk tumbuh pada media PDA yang sudah diberi perlakuan konsentrasi asap cair. Konsentrasi optimal asap cair kulit kayu akasia I alah konsentrasi 3% memiliki nilai Anti Fungal Activity (AFA) 100%, akan tetapi berbeda dengan asap cair ranting akasia konsentrasi optimal ialah 4,5% dengan nilai AFA 75,63% sudah termasuk dalam kategori sangat kuat. Tingkat aktivitas jamur sangat kuat apabila nilai AFA 75%.Kata kunci: Anti Fungal Activity (AFA), Asap Cair, Schizopyllum commune
