Abstract

Various vegetables are widely cultivated in Serang Village, District of Karangreja, Purbalingga Regency. This village is located at 1350 above sea level. Vegetable productions in Serang are often constrained by the presence of diseases caused by pathogenic fungi Colletotrichum sp. called anthracnose. However, there was no data regarding anthracnose attack in vegetable crops in Serang. This study aimed to find out the types of vegetable that were attacked by anthracnose disease as well as the intensity of the attack in a vegetable crops in Serang Village, Karangreja District, Purbalingga Regency. Vegetables with anthracnose were purposively selected from 10 different locations. The anthracnose disease was identified based on their symptoms and analyzed descriptively. The results showed that five different vegetable crops suffer from anthracnose, and the intensity of anthracnose ranges from 32% up to 52%. Those intensity percentages indicate that large part of vegetable crops in Serang Village was attacked by anthracnose and possibly cause a significant decrease in vegetable production in that village. Our results provide the first scientific data about anthracnose attack in Serang Village. The data is essential for the management of vegetable crops in Serang Village.

Abstract

Trigona bees' food resources can be determined either directly based on flowering plants live closed to the nest or based on pollen diversity inside the nest. There is no study about Trogona bee's food resources determination based on pollen diversity inside the bee colony's nest. This study aimed to determine plant food resources based on pollen diversity found inside the Trigona nest. This research was conducted in Serang village, sub-district of Karangreja, Purbalingga Regency. Pollen samples were taken from flowering plants lives around the nest and those in the nest and then were prepared using the acetolysis method. The variables observed were pollen morphology, with parameters such as unit, shape, size, aperture, and ornamentation. The data obtained were analyzed descriptively. Based on pollen diversity, 43 species and 22 plant families were live around Trigonanest in Serang Village. Forty-one pollen types were found inside the Trigonas' nest, with 37 of them are identic to the pollen collected from flowers around the nest. It can be concluded that 37 species of flowering plants could be determined as food resources for the Trigona bee based on pollen diversity inside the nest. This research provides the first data about feed resources for Trigona bee in Serang Village based on pollen diversity. The results provide essential information about food resources, which is vital for the development of Trigona bee cultivation.

Abstract

Vegetables polyculture system is potentially increasing pathogenic fungi diversity because various plant hosts are available. There is no data about patogenic fungi diversity at polyculture vegetable farming in Serang village, District of Karangreja, Purbalingga Regency. This study aimed to determine patogenic fungal diversity and disease percentage caused by the fungi at polyculture vegetable farming in Serang village, District of Karangreja, Purbalingga Regency. This research used purposive random sampling. Infected plants were collected at ten polyculture farming locations and fungal identification was performed at the laboratory. Fungi were identified morphologically based on the signs, symptoms, as well as macroscopic and microscopic characters. The fungi's pathogenity was determined by applying Koch's postulate test. The data were analyzed descriptively through literature comparison. The results showed that seven fungal species were found at polyculture farms in Serang Village. The obtained fungi were Colletotrichum sp., Fusarium sp., Alternaria sp., Septoria sp., Cercospora sp., Botryodiplodia sp., and Nigrospora sp. The lowest damage was 18.24% on tomato fruit infected by Fusarium sp. and the highest was on chili plants which was caused by Colletotrichum sp. The data is the first report for polycuture system. The obtained data has important implication for the management of vegetables farming in Serang Village.
