Abstract

In facing global challenges related to environmental degradation, schools play a role as strategic institutions in instilling environmental care values in students. Socialization with the theme “Environmentally Friendly Generation” is the first step in building the character of environmental care to provide knowledge and understanding related to environmental care to students at SMP Negeri 1 Kedungbanteng. The socialization was conducted for students in grades VII-IX of SMP Negeri 1 Kedungbanteng on November 22, 2024. An interactive socialization approach was used in community service through this socialization. The results of the socialization showed that students had understood the material given, as indicated by the evaluation results, which showed the average ability of students to answer questions correctly by 88%. As many as 90% of students answered evaluation questions correctly related to basic environmental concepts. However, aspects of the concept of recycling and renewable energy sources still need to be given an understanding.

Abstract

Downy mildew is one of the major patogen limiting maize productivity in Indonesia. Effective mitigation strategies are essential due to the significant yield losses it causes. Biological control is an environmentally viable alternative method of disease management. Bacillus spp. are biological control agent capable of producing metabolic chemicals that can inhibit plant infections, hence holding potential for downy mildew management. This study aimed to evaluate the effectiveness of Bacillus spp. from the maize rhizosphere to manage downy mildew and promote maize plant growth. The research employed a completely randomized block design, consisting of four treatments and six replications. The treatments comprised Bacillus amyloliquefaciens BB.R3, B. subtilis BK.R5, Bacillus spp. BK.R9, fungicides treatment (metalaxyl), and control group for comparison. The observed variables included spore germination, incubation period, disease incidence, disease severity, Area Under Disease Progression Curve (AUDPC), number of leaves, plant height, fresh shoot weight, and fresh root weight. The findings revealed that B. amyloliquefaciens BB.R3, B. subtilis BK.R5, and Bacillus spp. BK.R9 effectively inhibited downy mildew by decreasing spore germination by 80.55-100%, prolonging the incubation period, and inhibiting disease incidence by 20.37-53.70%, disease severity by 25.64-62.56%, and AUDPC by 22.21-63.37%. B. amyloliquefaciens BB.R3 can enhance plant growth by augmenting root weight by 122.63% and maize plant weight by 80.26%.   ABSTRAK   Penyakit bulai merupakan salah satu penyakit utama yang menghambat produksi jagung di Indonesia. Upaya pengelolaan penyakit bulai perlu dilakukan mengingat besarnya kehilangan yang ditimbulkan.  Pengendalian hayati merupakan salah satu alternatif pengendalian yang ramah lingkungan dan berkelanjutan. Bacillus spp. adalah bakteri yang mampu menghasilkan senyawa metabolik, dapat mengendalikan pathogen tanaman sehingga berpotensi sebagai pengendali penyakit bulai.  Penelitian ini bertujuan untuk mengetahui kemampuan Bacillus spp. asal rizosfer untuk mengendalikan penyakit bulai dan mengoptimalkan pertumbuhan tanaman jagung. Penelitian menggunakan Rancangan Acak Kelompok Lengkap, dengan 4 perlakuan dan 6 ulangan. Perlakuan meliputi Bacillus amyloliquefaciens BB.R3, Bacillus subtilis BK.R5, Bacillus spp.. BK.R9, serta fungisida (metalaksil) dan kontrol sebagai pembanding. Variabel yang diamati meliputi perkecambahan spora, masa inkubasi, kejadian penyakit, intensitas penyakit, AUDPC, jumlah daun, tinggi tanaman, bobot tanaman segar, dan bobot akar segar. Hasil penelitian menunjukkan B. amyloliquefaciens BB.R3, B. subtilis BK.R5, Bacillus spp.. BK.R9 mampu menekan penyakit bulai jagung, dengan menurunkan perkecambahan spora 80,55-100 %, menunda masa inkubasi, menurunkan kejadian penyakit sebesar 20,37-53,70 %, intensitas penyakit sebesar 25,64-62,56%, dan AUDPC sebesar 22,21-63,37%. B. amyloliquefaciens BB.R3 dapat memacu pertumbuhan tanaman, dengan meningkatkan bobot akar sebesar 122,63 % dan bobot tanaman jagung sebesar 80,26%.   Kata kunci: Bacillus, jagung, pengendalian hayati,  Peronosclerospora maydis, ramah lingkungan

Abstract

The agricultural sector's future in Indonesia heavily depends on the role of the younger generation. They have the potential to drive agriculture toward progress and sustainability. One group that plays an important role in Junior High School (SMP) students, particularly at SMPN 1 Sumbang in Banyumas Regency. This activity aims to enhance the skills and knowledge of students at SMP Negeri 1 Sumbang in horticultural crop cultivation, especially vegetables, as a strategic step to foster young people's interest in agriculture. The SMP Negeri 1 Sumbang community service activity was held on December 12, 2024. This program targeted 30 ninth-grade students and included counselling sessions, hands-on practice with teachers and students, and activity evaluations—an initial evaluation before counselling and a final evaluation afterwards. The evaluation results indicated an increase in students' understanding of vegetable cultivation techniques, with the initial understanding level rising from 33% to 85% after the final evaluation. This improvement demonstrates the success of the community service program in enhancing students' knowledge and skills in vegetable farming. However, this agricultural practice must be carried out continuously so that students' skills can keep developing.

Abstract

Botrytis cinerea, a fungal pathogen, is largely to blame for the significant decline in cherry tomato prices. Chitosan, a natural biopolymer, has been explored as an alternative coating material to enhance fruit resistance and preserve postharvest quality. This study looks at how well chitosan edible coatings, applied by spraying and dipping, can prevent Botrytis cinerea infection on cherry tomatoes. The fruits were intentionally infected by making cuts and soaking them in a solution containing the pathogen, and then they were treated with chitosan coatings. The coated fruits were incubated at room temperature for 14 days and assessed periodically on days 1, 7, and 14 for weight loss, disease incidence, and sugar content (°Brix). Results showed that the dip coating method significantly reduced weight loss and disease incidence compared to other treatments, with the lowest weight loss recorded at 0.87 grams and disease incidence at 22.22%. The highest sugar content was observed in the uncoated control group (7.23° Brix), indicating that coatings might slightly affect sweetness. Both ways of using chitosan successfully prevented the growth of Botrytis cinerea and kept the quality of cherry tomatoes satisfactory while they were stored. These findings suggest that chitosan edible coatings, especially when applied by dipping, offer a promising, environmentally friendly postharvest treatment to reduce decay and prolong the shelf life of cherry tomatoes.
