Abstract

Sustainable agriculture always utilises natural materials and avoids the use of synthetic materials in an effort to increase agricultural production, without damaging the environment. Understanding the meaning of sustainable agriculture to farmers is still not much done. Farmers of Cinanjung village, Tanjungsari sub-district, Sumedang Regency, are conventional horticultural farmers who mostly do not understand the concept of sustainable agriculture so that there are still many farmers who use synthetic fertilisers and synthetic pesticides in an effort to increase their production, without realising that it can harm the environment. The SITH ITB Community Service Team tried to provide an understanding of the importance of sustainable agriculture and training in the identification of plant pest organisms (OPT) and the production of biopesticides from surrounding plants, so that they could support the programme. The results of the Community Service Activities show that the existence of this community service programme is able to increase knowledge and understanding of sustainable agriculture and the skills of identification of plant pest organisms and biopesticide production skills from microbial resources and surrounding plants

Abstract

The biosynthesis of lovastatin, the anti-cholesterol compound, in oyster mushrooms (Pleurotus ostreatus), has the potential to be enhanced by utilizing phytohormones, which activate the expression of certain genes. This research aimed to determine the best type and concentration of phytohormone among auxin, gibberellin, and cytokinin, as well as the best mycelial colonization percentage in F2 medium to realize the greatest increase in lovastatin biosynthesis in oyster mushrooms. Lovastatin was extracted from the fruiting bodies and mycelia and analyzed by spectrophotometry. The analysis of CYP450 linked to lovastatin biosynthesis was conducted by quantitative polymerase chain reaction (qPCR) using samples containing the highest concentration of lovastatin. The results showed that adding phytohormones increased the lovastatin concentration in the fruiting bodies and mycelia of P. ostreatus. The highest lovastatin content was observed in the 10 ppm gibberellin treatment by applying 75% mycelial colonization in the F2 medium. Furthermore, this gibberellin treatment also demonstrated increased expression of the CYP450 gene in the fruiting bodies and mycelia. In conclusion, phytohormone treatments with the right timing and appropriate concentration increased lovastatin biosynthesis in P. ostreatus as well as related gene expression.

Abstract

Pertanian berkelanjutan adalah kegiatan yang memanfaatkan bahan alam seperti biofertilizer dan pupuk organik dengan meminimalkan penggunaan pupuk sintetik, untuk menjaga kesuburan alami tanah dan menghasilkan panen tinggi tanpa merusak lingkungan. Para petani di Desa Cinanjung, Kecamatan Tanjungsari, Kabupaten Sumedang, dilatih membuat biofertilizer dan pupuk organik dari limbah pertanian untuk diaplikasikan pada tanaman sayuran di pekarangan mereka. Kegiatan ini didasarkan pada hasil survei kondisi desa Cinanjung serta permasalahan dan solusi yang mungkin diterapkan. Hasil survei menunjukkan bahwa masyarakat setempat terbiasa menggunakan pupuk sintetik, padahal limbah pertanian dan rumah tangga memiliki potensi besar sebagai sumber daya untuk dijadikan pupuk hayati dan organik. Maka, ditetapkanlah kegiatan pelatihan pembuatan biofertilizer dan pupuk organik bagi petani Cinanjung yang tergabung dalam kelompok tani Nanjung Jaya. Pelatihan ini dihadiri sekitar 25 peserta dan dilakukan di balai pertemuan warga Desa Cinanjung. Hasil pelatihan menunjukkan peningkatan pemahaman peserta tentang pentingnya biofertilizer dan pupuk organik dalam pertanian berkelanjutan serta peningkatan keterampilan dalam membuat biofertilizer dan pupuk organik dengan memanfaatkan sumber daya setempat. Kesimpulan dari kegiatan ini adalah bahwa kegiatan pengabdian masyarakat yang dilakukan oleh Tim PPM dosen dan mahasiswa SITH ITB telah meningkatkan pemahaman tentang pentingnya pertanian berkelanjutan dengan memanfaatkan bahan-bahan alami. Upaya ini berhasil meningkatkan produksi tanpa menyebabkan kerusakan lingkungan bagi para petani di Desa Cinanjung, Kecamatan Tanjungsari, Kabupaten Sumedang.
