Preliminary Test of Agri-Environmental Scheme Implementation in Farmland in Northern Slope of Mount Slamet

An Agri-Environmental Scheme (AES) was designed to enhance flower availability in crops using local wild plants. The goals of this research were to determine the impact of four wild plants on three cash corps, focusing on the diversity and abundance of insect pollinators, and to test the efficacy of this scheme using farmland on the northern slope of Mount Slamet. This research was done using a split block design, with the three cash crops as blocks (strawberry [Fragaria x ananassa Duchesne], chili pepper [Capsicum spp.], and tomatoes [Solanum lycopersicum L.]) and four wild plant species as treatments (Cleome rutidosperma, Borreria laevicaulis, Euphorbia heterophylla, and Tridax procumbens) at different precentages (0, 5, 10, and 15 %) of cash crop plant density. The results show that growing wild plants with cash crops enhanced the abundance and diversity of insect pollinators. Moreover, the addition of wild plant species to the crops at four densities had significantly different effects on insect pollinators in terms of abundance and diversity. The combination of 15 % C. rutidospermae and tomatoes had the largest population of insect pollinators. From the experiments it concluded that an AES could be implemented in farmland on the northern slope of Mount Slamet

Keragaman Serangga Penyerbuk pada Pertanaman Strawbery yang Diselingi dengan Tanaman Borreria Laevicaulis

The productivity of strawberry (Fragaria sp.) depends on the presence of pollinator insects that need nectar or pollen as their food. The diversity and the population size of pollinator insects can be increased by the companion planting of Borreria laevicaulis among the strawberry. This research aimed to determine the diversity of pollinator insects of strawberry plantation companion by B. laevicaulis and to determine the relationship between the diversity of pollinator insects with the strawberry fruit produced. This research was conducted in the strawberry plantation of Serang Village, of the District Karangreja, Purbalingga, from June to August 2012. The research was designed to determine the effect of companion planting of B. laevicaulis at the 0%, 5%, 10%, and 15% of the total individuals of strawberry. The results showed that the companion planting of B. laevicaulis in the strawberry field did not affect the species diversity of pollinator insects. But the B. laevicaulis companion planting affected the amount of strawberry yielded. The maximum yield was obtained by planting B. laevicaulis at the 10% of the strawberry individuals; it was increased by 76.12% of the control without companion planting
