Cuaca Ekstrim Mengubah Nilai Indeks Ketahanan Tanaman Padi Terhadap Rebah
Get PDFKetahanan rebah varietas padi ditentukan berdasarkan indeks kerebahan IRRI (1988) yang terdiri dari : 0, 1, 3, 5, 7, dan 9. Nilai indeks 0 : sangat tahan rebah (tidak ada tanaman yang rebah), 1 : tahan rebah (tanaman rebah kurang dari 20%), 3 : agak tahan rebah (tanaman rebah 21 ̶ 40%), 5 : sedang (tanaman rebah 41 ̶ 60%), 7 : agak peka (tanaman rebah 61 ̶ 80%), dan 9 : peka (tanaman rebah lebih dari 80%). Evaluasi karakter kerebahan (Krb) tanaman padi dilakukan mengikuti Panduan Sistem Karakterisasi dan Evaluasi Tanaman Padi Kementan (2014). Kreteria dan metode evaluasi varietas padi terhadap ketahanan rebah tidak diukur untuk menghadapi kondisi cuaca ekstrim. Nilai indeks kerebahan berubah dengan terjadinya insiden cuaca ekstrim sehingga perlu dilakukan evaluasi terhadap kreteria ketahanan rebah suatu varietas bila akan ditanam di daerah yang rawan insiden cuaca ekstrim

JALUR INFEKSI Beauveria bassiana DAN Metarhizium anisopliae SEBAGAI PENGENDALI HAYATI COLEOPTERA:Oryctes rhinoceros L.
No full textRecent co-evolutionary studies of insect-pathogens have shown that entomopathogenic fungi have a greater potential for oral toxicity in terms of virulence in the mouth infection of insect pests. Therefore, it is necessary to conduct research on finding the route of infection of B. bassiana and M. anisopliae through the mouth in the larvae of the rhinoceros beetle O. rhinoceros. The purpose of this study was to analyze the path of infection of B. bassiana and M. anisopliae in O. rhinoceros larvae through exposure to the entompotagen fungus. The study was conducted at the Plant Protection Laboratory Politeknik Negeri Jember using a single factor Completely Randomized Design (CRD) with B. bassiana and M. anisopliae isolates from Temanggung, Jember and Jombang. Data analysis used Analysis of Variance and further analysis used Least Significant Difference Test at 5% level. The results showed that all isolates were able to infect and cause mortality in the test insects. MJb isolate had the highest effectiveness with the mortality rate of the test insects reaching 100% and the highest spore density with an average of 8.9 x 109 conidia/ml on day 6 after application. The hyphae that were abundant in the abdomen of cadaveric infected with M. anisopliae were different from the hyphae which grew more on the head of insects infected with B. bassiana, confirming previous research on the route of B. bassiana infection through oral toxicity. These results will be useful in providing new information regarding potential pathways of infection of B. bassiana in O. rhinoceros larvae through oral toxicity mechanisms, which until now have been very little reported.

Get PDFFixed assets have an important role for the smooth running of cooperative operations. Proper policy in the treatment of fixed asset accounting is needed in maximizing that important role. Users of financial statements urgently need information in accordance with the Financial Accounting Standards of Entities Without Public Accountability (SAK ETAP) so that an analysis of fixed asset treatment needs to be done to ensure whether the treatment of fixed assets has been in accordance with the ETAP SAK. The data used is secondary data consisting of the financial statements (balance sheet) of THE HMS Cooperative in 2018, data on ownership of the 2018 HMS Cooperative fixed assets (list of equipment, vehicles and furniture) along with the list of depreciation of cooperative fixed assets 2018. In data analysis the methods used are qualitative and quantitative methods. Based on the results of the analysis, it can be concluded that the fixed assets in the HMS Cooperative have been in accordance with SAK ETAP No. 15. In the recognition of fixed assets, cooperatives recognize the type of fixed assets by means of their acquisition, namely by cash purchase. Hms's cooperative fixed assets are depreciated using the straight line method. In termination, the HMS Co-operative has never stopped its fixed assets. HMS cooperative complies with SAK ETAP in its presentation, where fixed assets are presented in the balance sheet. However, HMS Cooperative does not disclose fixed assets because the cooperative does not make CAL
