Potalo dextrose and mango leaf extract agar media were found to be the most favourable for mycelial growth of <i>Pestalotia</i> spp. The optimum temperature for growth and sporulation was 25°C. Continuous light promoted mycelial growth and continuous darkness retarded it. The maximum percentage of germinated spores was obtained under intermittent daylight conditions. Germination of <i>Pestalotia</i> spores occurred at various stages of maturity. The percentage of germination decreased with the increase of the storage period in the host tissues, and after 12 months spores lost their viability completely. Mycelia in the same infected tissues, however, were found to be still alive and capable of producing new fructifications till 18 months. Morphological characters of the fungus, and mode of spore germination were also investigated.

The authors have investigated the effect of many media on the development of 10 isolates of <i>Pyricularia oryzae</i> in order to obtain abundant sporulation, to facilitate the determination of physiological races and preparation of phytopathological tested.

In 2008, Indonesia became a member of the G20, and it is estimated that in 2030 it will be in the top seventh economic countries if it can keep growing. Nevertheless, high economic growth was followed by an inequality problem. This study will analyze the wage gap between manufacturing and non-manufacturing workers. Using Sakernas 2020 and the Mincer wage model regression, the result showed that all independent variables: age, level of education, gender, region of residence, marital status, toddler, disability status, and certificate training influence wages for both manufacturing and non-manufacturing workers. Next, the Blinder-Oaxaca method decomposes the wage gap between both groups. It is shown that manufacturing workers get higher wages than non-manufacturing workers because of differences in the characteristic of workers and also industry attributes which, in this case, capital intensity.
