Abstract

Trichoderma sp. is a type of fungus that exists in the root zone of plants and is able to protect plants from disease. This biological agent is known to be able to overcome the attack of fusarium wilt which often attacks chili plants. Tuban Regency became a chili center area because in 2022 it managed to produce 36,528 tons of cayenne pepper and 6,760.98 tons of large chili. One of the sub-districts in Tuban Regency that has the highest chili production rate is Grabagan Sub-district with a production rate of 81.91%. The high rate of chili production, both cayenne pepper and large chili, is proportional to the increasing challenges of chili cultivation. This community service activity has the main objective of introducing biopesticides from the biological agent Trichoderma sp. to chili farmers in Grabagan District, Tuban Regency as a solution to chili wilt disease caused by the fungus Fusarium sp. Community Service activities initiated by the Faculty of Agriculture Lecturer Team of Sunan Bonang University Tuban have been carried out by involving 13 chili farmers in Grabagan District at the Grabagan District Extension and Food Security Center (BPKP). This activity contains counseling related to the propagation of Trichoderma sp. fungi in a simple way and sustainable agriculture with the concept of Back to Nature. The activity was complemented by hands-on practice of Trichoderma sp. fungi propagation using rice as a substrate. Based on the questionnaire distributed to the participants, it was found that 10 out of 13 chili farmers in Grabagan sub-district still depend on the use of synthetic pesticides. After receiving the counseling, 12 out of 13 chili farmers expressed their willingness to implement environmentally friendly agriculture by utilizing biological agents Trichoderma sp.

Abstract

Bacillus sp. is well known for its functional capabilities such as solubilizing phosphorus (P) and potassium (K), and fixing nitrogen (N2). These bacteria can form endospores under stressed conditions, allowing long-term survival and application in biotechnological fields. This study aims to isolate Bacillus sp. capable of forming endospores and evaluates their viability on different carriers, specifically biochar and oil spill dispersant (OSD), to enhance biodegradation in contaminated environments. Soil samples from the bamboo rhizosphere were heat-shocked to isolate endospore-forming Bacillus strains, with the isolate identified as Bacillus pseudomycoides RAY21 through 16S rRNA sequencing. This strain exhibited Gram-positive characteristics, formed endospores, and demonstrated potential on various media such as Pikovskaya, Alexandrov, and N-Free Mannitol. The physiological characterization indicated optimal growth in a pH range of 6-8, salinity up to 3.5%, and thermophilic properties. Endospores from B. pseudomycoides RAY21 and B. subtilis CYA27 were tested on biochar and OSD as carriers. The results showed that endospores adhered better to biochar, but their viability was more stable in OSD over time. Notably, B. pseudomycoides RAY21 on OSD degraded 23.43% of total petroleum hydrocarbons (TPH), outperforming B. subtilis CYA27 (21.62%). In conclusion, the study demonstrates the potential of using Bacillus endospores on OSD as an effective carrier for bioremediation, particularly in degrading petroleum hydrocarbons. Future research should focus on optimizing carrier materials and exploring field-scale applications for enhanced environmental cleanup.

Abstract

Dampak perubahan iklim terhadap berbagai aspek kehidupan telah dirasakan oleh masyarakat global, termasuk Kabupaten Tuban, Jawa Timur. Dalam hal ini, kontribusi sektor pertanian terhadap emisi gas rumah kaca sebagai penyumbang perubahan iklim di Kabupaten Tuban cukup besar. Jika tidak diimbangi dengan upaya mitigasi, maka emisi gas rumah kaca akan semakin meningkat setiap tahunnya. Memperbanyak vegetasi, terutama pohon yang berfungsi sebagai penyerap karbon di atmosfer, merupakan salah satu upaya mitigasi yang dapat dilakukan. Namun, Kabupaten Tuban justru kehilangan beberapa lahan hutan. Universitas Sunan Bonang Tuban terletak di daerah perkotaan, namun spesies pohon di area kampus masih tetap dipertahankan. Hal ini merupakan salah satu upaya pelestarian lingkungan yang dilakukan oleh pihak kampus. Sebagai bentuk partisipasi kampus dalam mengurangi pemanasan global, maka perlu dilakukan identifikasi jenis pohon yang ada di dalam kampus, stok karbon, maupun jumlah karbon yang diserap dari atmosfer. Penelitian ini dilakukan pada bulan Mei hingga Juli 2022 di area kampus Universitas Sunan Bonang Tuban. Semua jenis spesies pohon akan dievaluasi berdasarkan biomassa per diameter pohon dan estimasi jumlah karbon yang diserap oleh tegakan. Berdasarkan hasil penelitian, terdapat sebanyak 66 pohon jati di kampus Universitas Sunan Bonang. Pohon mimba menyumbangkan cadangan karbon paling banyak, yaitu 239,34 kg atau 41 persen dari total cadangan karbon di Universitas Sunan Bonang, yaitu 581,27 kg atau 2,1 ton CO2 yang diserap dari atmosfer.

Abstract

Tanaman memerlukan nutrisi yang cukup untuk pertumbuhan dan perkembangan, salah satunya yaitu fosfor (P). Namun tanaman hanya dapat menyerap P dari tanah dalam bentuk ion fosfat (H2PO4- dan HPO42-). Tantangan besar yang dilakukan untuk menyediakan P terlarut atau tersedia, terjawab oleh penemuan Bakteri Pelarut Fosfat (BPF). Mikrob ini menghasilkan asam-asam organik yang dapat melarutkan senyawa fosfat kompleks dan atau mengikat kation dari ion (PO43-) untuk melepaskan P tersedia dalam tanah. Areal rhizosfer tanah memiliki potensi keragaman mikrob yang tinggi karena menyediakan sumber makanan (eksudat) yang dikeluarkan dari akar tanaman. Penelitian ini bertujuan menentukan kualitas isolat BPF dari ekosistem perkebunan singkong dan hutan Kampus IPB Dramaga dengan Indeks Pelarut Fosfat (IPF) tertinggi pada berbagai sumber P dan variasi pH serta menentukan isolat BPF yang bersifat non-patogenik terhadap manusia, hewan, dan tanaman. Penelitian ini diawali dengan mengisolasi BPF dari areal rhizosfer, menumbuhkannya pada media selektif Pikovskaya, identifikasi morfologi koloni secara makroskopis, seleksi koloni BPF yang menghasilkan halozone (zona bening), mengukur IPF, dan mengujinya pada media Pikovskaya dengan berbagai sumber P dan tingkatan pH. Hasil isolasi menunjukkan adanya 9 isolat 2 diantaranya dari tegakan hutan dan 7 dari perkebunan singkong yang menghasilkan halozone. Isolat 6P dan 7P dari tegakan hutan memiliki IPF tertinggi berturut-turut sebesar 3,10 dan 3,33. Adapun isolat BPF hanya dapat mengasilkan halozone pada media sumber P dari kompleks Ca-P dengan kondisi pH basa dan pH tanah. Dari 9 isolat terpilih, 6 diantaranya yaitu isolat 1P, 3P, 4P, 6P, 7P, dan 9P teruji bersifat non-patogen terhadap sel manusia, hewan, maupun tanaman.

Abstract

Tomatoes are one of the most widely cultivated horticultural crops in the region Tuban Regency. One of the women farmer groups that often cultivate tomatoes is the Farmers Women’s Group in is the Farmers Women’s Group in Widang Subdistrict. The Farmers Women’s Group has tomato plants with high yields. But sometimes the price of tomatoes is very low causing the Farmers Women’s Group to experience significant losses. The author sees this condition as an opportunity to increase the use value of tomatoes so that they have a higher price. One of the efforts that can be done is by using tomatoes as raw material for making candied dried tomatoes. Candied dried tomatoes are a very popular food and have wide market opportunities. This has been proven by the high sales of candied dried tomatoes in several regions in Indonesia. The author sincerely hopes that this community service activity will be able to increase the income of the Farmers Women’s Group in Widang District. The Farmer Women's Group is able to make candied dried tomatoes into one of the foods and souvenirs that are in demand by tourists visiting the Tuban Regency area. Community service activities were carried out at the Agricultural Extension Center of Widang District, Tuban Regency, which was attended by around 15 farm women. This activity contains counseling related to the innovation of candied tomatoes, followed by planning and implementing activities to make sweets made from tomato fruit. Armed with knowledge and practice, participants from the Widang District Women Farmers Group were interested and planned to apply the idea and innovation of candied dried tomatoes during the next harvest season.
