Curly chili is a horticultural product with high nutritional value, greatly demanded as a distinctive complement or flavoring for dishes due to its unique taste and aroma. Despite the increasing ...demand for chilies, production has not followed suit, mainly due to disruption caused by viruses transmitted by Bemisia tabaci and Thrips sp. This study aimed to investigate the effect of tobacco extract on the growth and development of viral diseases in curly chili. Conducted at Kwangsang Village, Jumapolo District, Karanganyar Regency, from September to December 2021, the research was designed using a completely randomized block design, with treatment doses of tobacco extract at 0 mL/L, 1 mL/L, 2 mL/L, 3 mL/L, and 4 mL/L, labeled J0, J1, J2, J3, and J4, respectively. The results indicated that the variabels, i.e. plant height, number of leaves, number of fruits, and fruit weight per plant, were significantly affected by the tobacco extract. Similarly, the disease incidence and severity of viral infection were significantly influenced by the tobacco extract application. The yield decrease in curly chili was attributed to virus infection by Bemisia tabaci and Thrips sp., which caused chlorosis and mosaic symptoms on the leaves. Although the affected plants did not die, they experienced a yield reduction. The application of tobacco extract significantly reduced the percentage of incidence and severityof virus infection on curly chili. The highest disease incidence was 35.42% (J0) and disease severity was 70.92% (J0), while the lowest disease incidence was 14.58% (J4) and disease severity was 20.58% (J4).
Sugarcane (Saccharum officinarum) is a high-value economical crops, only grows in tropical climates of Java and parts of Sumatra. Ratoon stunting disease (RSD) is a vascular disease in sugarcane ...which its visual symptoms is difficult to detect. The disease has spread across the sugarcane plantations in Indonesia with the percentage of attacks 10-100%. The use of buds chips treatment of seedling plant is an act of reducing pathogen development. The research effect of hot water treatment / HWT (0, 30, 60, and 90 min) and dose application of Trichoderma sp. (0, 25, and 50 g) using 864 varieties, is designed with a completely randomized factorial design. The results showed that Trichoderma sp. able to infect the roots and stems of seedling age 3 months, part of plant tissue increase of protein and proline content, decrease of glucose content so that increase resistance and health in the growth of sugarcane seedling before planting in the land.Tanaman tebu (Saccharum officinarum) adalah tanaman yang bernilai ekonomi tinggi, hanya tumbuh di daerah beriklim tropis terutama di Jawa dan sebagian Sumatra. Penyakit ratoon stunting disease (RSD) merupakan penyakit pembuluh pada tebu yang sulit dideteksi gejala visualnya. Penyakit tersebut telah tersebar di seluruh pertanaman tebu di Indonesia dengan presentase serangan mencapai 10-100%. Penggunaan bahan tanam benih asal mata tunas (bud chip) dapat mengurangi perkembangan patogen. Penelitian pengaruh waktu perendaman air panas (0, 30, 60, dan 90 menit) dan aplikasi dosis jamur Trichoderma sp (0, 25, dan 50 g) terhadap pertumbuhan benih tebu klon 864, dirancang dengan menggunakan rancangan acak lengkap faktorial. Hasil penelitian menunjukkan bahwa jamur Trichoderma sp mampu menginfeksi bagian akar dan batang benih umur 3 bulan, pada bagian jaringan tanaman terjadi peningkatan kadar protein dan prolin serta penurunan kadar glukosa sehingga meningkatkan ketahanan dan kesehatan pada pertumbuhan awal benih tebu sebelum ditanam di lahan.

Tujuan penelitian ini adalah menguji perbaikan pertumbuhan dan hasil stevia (Stevia rebaudiana Bertoni M) melalui penggunaan Trichoderma sp. Perbanyakan Trichoderma sp. dilakukan di ...laboratorium Balai Proteksi Perkebunan di Salatiga Jawa Tengah. Penelitian dirancang menggunakan rancangan factorial dengan dua faktor. Faktor pertama adalah inokulasi Trichoderma sp (To = tanpa Trichoderma sp. & T1 = menggunakan Trichoderma sp. 100 g. Faktor kedua adalah variasi aplikasi perlakuan yaitu: 1). S0 = tanpa perlakuan, 2). S1 = 10 hari sebelum tanam, 3). S3 = tanama dan 4). S3 = 10 hari setelah tanam. Tiap perlakuan diulang tiga ulangan, tiap ulangan terdiri dari 16 tanaman. Hasil penelitian menunjukkan bahwa inokulasi Trichoderma sp. dan aplikasi perlakuan S3 = 10 hari setelah tanam dapat meningkatkan pertumbuhan dan hasil dari tanaman tevia. Abstract
The object of this research was examine to repair of growth and yield of stevia (Stevia rebaudiana Bertoni M) by Trichoderma sp. application. Reproduction of Trichoderma sp. performed in the laboratory center of Protection plantation Central of Java at Salatiga.The experiment was arranged in a completely randomized completely factorial design, consisted of two factors. The first factor was Trichoderma sp inoculation which were To = without Trichoderma sp. and T1 = Trichoderma sp. 100 g. The second factor was variation of plant application treatment, which were 1). S0 = without treatment, 2). S1 = 10 days before of planting , 3). S3 = planting and 4). S3 = 10 days after planting. Each treatment was repeated three times and each replicate consisted of 16 plants. The result showed that that the inoculation of Trichoderma sp. and application of treatmen 4 is S3= 10 days after planting increases plant growth and yields of stevia.

The ligand-induced internalization of epidermal growth factor receptor (EGFR) is generally considered to attenuate downstream signaling via its endosomal degradation. However, the endocytosis of an ...oncogenic EGFR variant III (EGFRvIII) is impaired, which leads to persistent signaling from the cell surface, thereby promoting the proliferation and survival of glioblastoma multiforme (GBM) cells. Cellular stress triggers the non-canonical endocytosis-recycling of EGFR by p38-mediated phosphorylation. In the present study, we used temozolomide (TMZ), the standard chemotherapeutic agent for the treatment of GBM patients, to examine whether EGFRvIII is controlled by a non-canonical mechanism. TMZ triggered the endocytic trafficking of serine phosphorylated EGFRvIII. Moreover, phosphorylation and endocytosis were abrogated by the selective p38 inhibitor SB203580, but not gefitinib, indicating that EGFRvIII is recruited to p38-mediated non-canonical endocytosis. The combination of TMZ and SB203580 also showed potential inhibitory effects on the proliferation and motility of glioblastoma cells.

Binucleate Rhizoctonia (BNR) fungi are essential for the germination of vanilla seeds. Chemical control of the soil-borne pathogen might adversely affect BNR. The purpose of this study is to ...determine the effect of Nicotiana tabacum extract biopesticides and Fusarium oxysporum f.sp. vanillae (Fusarium) on vanilla plant nutrient content induced by BNR. Materials and Methods. The research design was completely randomized design with two factors and three replications. The first factor was biopesticide (dosage of 0, 10, 20, and 30 ml/seedling), and the second factor was the application of Fusarium. Results. The increase in the nitrogen, phosphorus, and potassium content of vanilla was affected by biopesticides and Fusarium inoculation. Fusarium inoculation has no significant effect on nitrogen and phosphorus levels but significantly affects potassium levels. The biopesticide dosage is significant for nitrogen, phosphorus, and potassium. The interaction of biopesticides with Fusarium inoculation did not significantly affect the parameters of nitrogen and phosphorus content, but significantly affected potassium content. Conclusion. The application of biopesticides and Fusarium inoculation after induction of BNR can increase nitrogen, phosphorus, and potassium content of vanilla plants.

ABSTRACT
The purpose of this analysis is to map the contribution of methane gas and nitrous oxide from the livestock sector in each region in East Java Province as a basis for planning in the development of sustainable and environmentally friendly livestock areas. The analysis method uses a Tier 1 analysis approach. The data used is secondary data from the BPS East Java in 2021. The results of the analysis show that the greenhouse gas load in East Java Province is CH4 as much as 221.80 Gg CH4 per year and N2O as much as 168.42 Gg N2O per year where the load profile is uneven for each district/city. The highest greenhouse gas load was found in Malang Regency. The highest greenhouse gas contributor from the livestock sub-sector is beef cattle with 75.20% CH4 and 52.30% N2O of the total livestock sector.
