Mahameru cultivar is high salinity tolerant cultivar. The previous study result showed Mahameru cultivar could tolerate 140 mM NaCl, but Cilacap Coast salinity levels often reaching 200 mM NaCl. A research of salinity stress on Mahameru cultivar at 200 mM NaCl have not conducted yet. Therefore to conduct the research of Mahameru at high salinity stress to obtained high salinity tolerant soybean cultivar. The observed variables are anatomy (epidermis thickness, the density of stomata and trichomes, palisade thickness) physiology (the dry weight of roots and canopy, the content of chlorophyll a and b) Production (whole pod, total filled pod, total empty pod, weight per one-hundred beans). The salinity treatment was 0, 50,100, 150, 200 mM NaCl given at three days before planting and twenty-one days after planting. The data of anatomy and physiology was taken at forty-five days after planting. The production data was taken when soybean plants turned brown. The result indicates that salinity affects anatomy characteristic of leaf, higher the salinity increasing epidermis thickness and the density of stomata and trichomes. Salinity affected the content of chlorophyll a and b. Higher the salinity increased the content of chlorophyll a and b. Salinity did not affect soybean production. Based on this study Mahameru cultivar is resistant to salinity up to 200 mM NaCl. The benefit of this research help to enhance national soybean production with utilization coastal land for soybean planting Mahameru cultivar.

Abstract. Abbas M, Sukarsa. 2022. Type and size of pollen collected by Tetragonula laeviceps at various altitudes. Biodiversitas 23: 1567-1575. Pollen’s type and size are affected by altitude. No study about pollen types and sizes collected Tetragonula laeviceps at various altitudes in Banyumas District, Central Java, Indonesia. This study was aimed to analyze pollen types and sizes collected at various altitudes in Banyumas District. The pollen samples were collected using a random sampling technique at each altitude, namely 46.7 m asl, 317 m asl, and 912 m asl. The pollen samples were collected from flowers around and inside the nest, then prepared using acetolysis. The parameters include pollen morphology, pollen’s polar (P) diameter, and the pollen's equatorial (E) diameter. The morphological characteristics and pollen diameter were analyzed statistically using analysis of variance. Pollens’ type was not affected by altitudes. However, pollen’s diameter was significantly different among altitudes, with the largest pollen size was observed at the highest altitude and the smallest were observed at the lowest altitude. The data are vital for meliponid culture at various altitudes.

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.
