Abstract

Anthracnose disease is one of the diseases in chili plants that can reduce yields by up to 80%. This study aims to determine the effectiveness and optimal concentration of natural fungicides from cloves and cumin in reducing the incidence and intensity of anthracnose disease (Colletotrichum sp.) attack directly on large chili plants in the field. The research was conducted in Sumberejo Village, Ngablak District, Magelang Regency. The study used a completely randomized design (CRD) with eight treatments and four replications. The extract treatments used clove leaves and cumin leaves with concentrations of 1%, 2%, and 3%, and no treatment and synthetic fungicides. The variables observed in this study were disease incidence, intensity of attack, and total fruit weight at harvest. The use of pesticides in the study showed significant differences from that of the control. The best natural fungicides for disease incidence in this study were CK3 (1,79%) and JK3 (2,94%), while the best natural fungicide treatments for attack intensity in this study were CK3 (11,25%) and JK3 (16,25%). Applying clove and cumin leaf fungicides to plants does not reduce crop yields.

Abstract

Fruit flies (Bactrocera spp.) are pests that attack cayenne peppers, with attacks reaching 100%. Generally, farmers use synthetic insecticides, but in the long term this can disrupt the balance of the ecosystem and trigger pest outbreaks and resistance—integrated pest control by planting refugia as a micro-habitat for natural enemies. Marigolds and zinnias were chosen as refugia plants. The aim of the research was to determine the types of fruit flies that attack chili plants, the symptoms of fruit fly attacks on chili fruit, the effectiveness of marigold and zinnia plants in reducing the intensity of chili plant attacks, and external factors that influence the efficacy of refugia marigold and zinnia plants. The research was conducted in July – October 2023 in Jlarem Village, Gladaksari District, Boyolali Regency, using a Randomized Block Design (RAK) with four treatments, namely control, marigold, zinnia, and a combination of both, using six replications so that there were 24 experimental units with ten plants in each experimental unit. This research used a hygrometer thermometer (HTC2), camera, net, and binocular microscope. Observation variables include the type of fruit fly, attack symptoms, attack intensity, and external factors. The types of fruit flies found in the study area were Bactrocera dorsalis, Bactrocera umbrosa, and Bactrocera carambolae. Symptoms that arise due to fruit fly attacks on chili fruit are black spots on the skin of the fruit, which become more expansive over time, causing the fruit to rot and fall prematurely. Refugia planting effectively reduced the intensity of fruit fly attacks, with the lowest attack intensity in the combination treatment of marigold and zinnia at 22.16%. Several external factors influence the effectiveness of refugia in controlling fruit flies, namely environmental temperature and humidity and the types of plants growing around the cultivated land.

Abstract

Hawar daun bakteri (HDB) merupakan penyakit yang menyerang tanaman padi dan disebabkan oleh bakteri Xanthomonas oryzae.Selama ini petani menanggulangi penyakit HDB ini dengan cara  menyemprotkan bakterisida,  pergiliran tanaman yang bukan inang patogen, dan menanam varietas tahan penyakit. Akan tetapi, pengendalian tersebut belum memberikan hasil yang maksimal, karena keragaman strain bakteri Xanthomonas oryzae. Pemberian bakterisida ini masih belum bisa menekan pertumbuhan bakteri sepenuhnya melainkan, hanya bisa memperlambat laju pertumbuhan bakteri Xanthomonas oryzae dan kemungkinan beresiko membunuh bakteri yang menguntungkan. Oleh karena itu, perlu dilakukan upaya untuk mengendalikan bakteri Xanthomonas oryzae dengan mempertimbangkan bakteriofag sebagai agen biokontrol untuk menginfeksi bakteri Xanthomonas oryzae. Metode untuk mengisolasi bakteriofag Xanthomonas oryzae  diawali dengan  pengambilan sampel tanah di lahan sawah dengan cara transek sampling, isolasi, purifikasi, dan propagasi bakteriofag. Pengujian stabilitas bakteriofag berfungsi untuk mengetahui kekuatan partikel bakteriofag dapat bertahan terhadap pH asam dan basa. Hasil penelitian menunjukkan bahwa terdapat 3 sampel bakteriofag yang berhasil diisolasi yaitu K1 (Kecandran 1), K2 (Kecandran 2), dan K3  (Kecandran 3). Hasil uji stabilitas bakteriofag terhadap pH menunjukan ketiga sampel diperoleh titer bakteriofag stabil pada pH 7 dan pH 9, sedangkan pada pH 2 dan pH 5 bakteriofag cenderung mengalami penurunan titer dan menunjukkan tidak mampu bertahan pada kondisi asam. Dari ketiga sampel tersebut, pada pH 12 menunjukkan adanya penurunan titer yang mengakibatkan sebagian besar partikel bakteriofag tidak tahan terhadap kondisi basa.

Abstract

The excessive use of synthetic chemical pesticides in controlling plant diseases poses significant challenges to sustainable agriculture. As an environmentally friendly alternative, plant growth-promoting rhizobacteria (PGPR) have shown promise by colonizing plant roots and forming symbiotic relationships that enhance plant growth and suppress plant pathogens. Research on the isolation of PGPR from ginger (Zingiber officinale) rhizosphere in Indonesia remains limited, highlighting the need for further exploration to support genetic resource conservation and sustainable agricultural practices. This study aims to evaluate the potential of PGPR isolates from Z. officinale rhizosphere in Semarang, Indonesia, as biological control agents. Isolates were characterized based on morphology, biochemical traits, and their antagonistic activity against fungal pathogens, including Fusarium oxysporum, Colletotrichum sp., and Alternaria sp. A total of 14 isolates were obtained, exhibiting diverse morphological, biochemical, and antagonistic properties. Among them, isolate 235A2 demonstrated the highest potential as a biological control agent, with capabilities including phosphate solubilization, nitrogen fixation, protease enzyme production, and significant inhibition rates of F. oxysporum (13.79%), Colletotrichum sp. (55.56%), and Alternaria sp. (35.61%) in vitro. These findings underscore the potential of PGPR as a sustainable alternative for biological control of plant pathogens, supporting both enhanced plant productivity and environmental conservation.

Abstract

The use of synthetic pesticides is not effective in reducing the prevalence of disease because it produces residues and does not support biodiversity. This is an unwise practice and can cause problems in the future.  The use of endophytic microorganisms is widely used to control plant diseases and pests, because it is known to have various pathogen inhibition mechanisms. Biological agents that are used to inhibit plant pathogens and have been widely developed, one of which is endophytic bacteria. The purpose of the research was to evaluate the potential of endophytic bacterial isolate from ginger plants as biological control agents. The type of research used is descriptive and exploratory. Sampling of healthy ginger plants was carried out at 5 points in two sub-districts, namely Getasan and Sumowono, Semarang Regency. Isolation is carried out by taking healthy ginger plants from the roots, rhizomes, fronds, and leaves. Characterization and selection of isolates were carried out by testing their phosphate dissolving ability, nitrogen anchoring, amylase and protease activities, and antagonist tests with Fusarium oxysporum in vitro. The results of this study are that (1) 20 pure isolates were successfully isolated consisting of 2 isolates derived from leaves, 4 isolates from fronds, 8 isolates from roots, and 6 isolates from rhizomes; (2) D91 isolate has the potential as a biological agent with an antagonist mechanism of 86.91% supported by protease enzyme activity, able to dissolve phosphate and anchor nitrogen.

Abstract

Sri Lankan Cassava Mosaic Virus (SLCMV) has emerged as a significant threat to cassava production in Southeast Asia since its initial detection in Cambodia in 2015, with recent outbreaks in Vietnam and Thailand and its first detection in Australia in 2024. This viral disease, transmitted by the whitefly Bemisia tabaci and infected planting materials, poses a substantial risk to Indonesia's cassava industry. Studies from affected countries demonstrate yield losses of 16-33% and starch content reductions of 22-38% in infected plants. This review analyzes SLCMV's current status and potential impacts on Indonesian cassava production and proposes management strategies based on regional experiences. We identify critical risk factors, including widespread vector presence and informal planting material exchange networks. Recommended preventive measures include strengthening quarantine systems, implementing enhanced surveillance programs, developing rapid diagnostic capabilities, and establishing clean seed certification systems. Our findings emphasize the urgent need for coordinated action to protect Indonesia's cassava industry from this emerging pathogen.

Abstract

Rice is Indonesia’s first staple food crop, planted throughout the year in irrigated rice fields. Finding an efficient method of producing rice seedlings outside the paddy fields is necessary. This research aims to determine the optimal shelf levels in open fields to support seedling rice growth and chlorophyll content and identify suitable lighting alternatives to light-emitting diode (LED) growth lights for supporting indoor seedling rice growth. This study used thirteen treatment variations, each repeated five times in a Randomized Block Design. The observational data were analyzed utilizing ANOVA, standard deviation, correlation, and the Honesty Significant Differences (HSD) test at a 5% significance level. The study's results were in the open field. The seedlings on the third level of shelves received the highest intensity of sunlight so that the chlorophyll content, seedling height, and number of leaves were relatively higher than those on the second and first level shelves. In greenhouse cultivation, the substitution for LED grows light until 150 Watts between 12 and 14 hours, causing low light intensity, chlorophyll levels, seedling height, and fewer leaves than in open fields.

Abstract

Desa Purworejo adalah satu dari 17 desa di Kecamatan Suruh Kabupaten Semarang, terletak di antara Kota Salatiga dengan Kabupaten Boyolali, dengan luas wilayah 169,52 ha terdiri atas lahan sawah 101,14 ha, tegalan 9,70 ha dan non pertanian 58,68 ha. Permasalahan pertanian yang dihadapi antara lain: luas kepemilikan lahan sekitar 0,32 ha/kk; penggunaan pupuk kimiawi/anorganik sangat tinggi sehingga lahan pertanian menjadi semakin “sakit”; penggunaan pembasmi hama dan penyakit berbahan kimia yang tinggi; ancaman hama tikus; pengetahuan petani masih sangat terbatas; serta keterlibatan petani dalam kegiatan-kegiatan kelompok tani masih sangat terbatas. Di pihak lain pengetahuan para pengurus kelompok tani juga masih kurang; serta jenis padi yang dihasilkan kualitas medium sehingga harganya relatif murah di pasar. Karena produktivitas rencah maka sebagian besar hasil padi masih untuk memenuhi kebutuhan keluarga. Petani belum mampu dan tidak berani menanam padi organik dengan kualitas premium yang sebenarnya memiliki harga lebih tinggi di pasar. Solusi permasalahan pertanian dilaksanakan melalui program Program Kemitraan Masyarakat dengan Peningkatan Keberdayaan dan Pendapatan Kelompok Tani Dompon Melalui Penanaman Padi Organik Premium dan Penangkaran Burung Hantu (Tyto Alba). Melalui kegiatan PKM ini terjadi perubahan perilaku petani di kelompok tani Dompon untuk mulai menanam tanaman organik dan penangkaran burung hantu sehingga hama tikus bisa dihindari. Anggota Kelompok Tani Dompon dapat: 1) belajar dan menerapkan teknologi pertanian terpadu yang ramah lingkungan; 2) produktivitas dan produksi lahan sawahnya meningkat; 3) menghasilkan produk beras organik kualitas premium; serta 4) membasmi hama tikus dengan cara yang lebih ramah lingkungan menggunakan burung hantu (Tyto alba) yang menjadi musuh alami tikus.
