Abstract

Large ruminants, consisting of cattle and buffalo, have played an important role in human life from the past to the present. Information about the utilization of large ruminants was often found in inscriptions in ancient Java. Unfortunately, the diversity of these large ruminants was not described in detail. The reliefs of the temples can be used as a consideration in understanding the diversity of large ruminants based on the morphological characteristics carved in the reliefs. Borobudur Temple, a historical building from the 8th century AD which was rich in reliefs, can be used as a data source to find information about the diversity of the large ruminants in Java. The aims of this study was to find the diversity of the large ruminants in Java in the 8th century based on the reliefs at Borobudur Temple. The research was conducted by observing various large ruminant images contained in the reliefs of Borobudur Temple. The results of the observations were interpreted and clustered based on their morphological characteristics. The results showed that there were ten relief panels containing images of cattle and nine relief panels containing images of buffalo. Based on the observed morphological characteristics, it could be concluded that there was only one breed of cattle and buffalo, respectively zebu (Bos indicus) and wild buffalo (Bubalus arnee).

Abstract

Strawberry (Fragaria sp.) is a horticultural plant originating from the Americas. Strawberries have a distinctive sweet and refreshing taste, and contain lots of vitamins and antioxidants that are useful for body health. But strawberries are also easily damaged. This damage can be caused by spoilage microorganisms such as bacteria and fungi that can grow if conditions permit such as the presence of appropriate temperature and humidity conditions. In this experiment, aims to isolate pathogenic microorganisms that cause disease in symptomatic strawberries and prove that these pathogens actually cause disease using Koch's Postulates method and then descriptive analysis is carried out. From the experimental results, it was found that soft rot disease in strawberries was characterized by rotten fruit parts that looked wet, slightly brownish in color, slimy, there were fine white threads and emitted a foul odor with a percentage of IP (disease occurrence) of 100% and KP (disease severity) of 92.66% where based on the score the damage was the highest.
