Abstrak: The Government through the Ministry of Agriculture has released more than 72 soybean varieties. High yielding varieties is one of the factors that play an important role in increasing the productivity of soybean. Lack of access the information on soybean high yielding varieties led to the knowledge level of farmers about soybean varieties are also low. This is demonstrated by the habits of farmers who did not use high yielding varieties of soybean. Farmers were not using varieties in rotation. They use varieties based on experience and not based on the knowledge or the results of the valid study. It causes decreased productivity and resilience of soybeans. Limitations of experts to disseminate information about soybean varieties and information on pests and diseases, it is necessary to build a system that can manage and store information that can be accessed easily by farmers. Soybean varieties electoral system (SIPEKSOY) is one of the systems that can be used to overcome these limitations. The purpose of this study was developed a system of the selection of soybean high yielding varieties based on online. The method used adopted SDLC method including planning, analysis, design, implementation, testing, and evaluation. The implementation of this system is using PHP and MySQL. The electoral system of soybean high yielding varieties produced was presented in three form, namely the selection of soybean varieties in the search of varieties; searching of varieties by category determination, namely potential yield category, ripe pod age, seed coat color, seed size, the adaptation of land or area, plant height, security to pests or diseases; and the search based on the keywords entered by the user. This soybean varieties electoral system simplifies and speeds up the user, e.g. extension workers, farmers, society, and experts in obtaining information about high yielding varieties of soybean.

Abstrak: Soybean is one of the commodities that is instrumental in food needs. However, Indonesia has not been able to fulfill its own need of soybean. Some problems faced by soybean farmers include the selection of good varieties, disruption of pest and diseases. Because of the limitations of experts to disseminate information about soybeans, it is necessary to build a system that can manage and store information so that the information can be easily accessed. To this end, we utilize the system development life cycle to develop information of soybean pests and diseases into an information system kedelai.ipb.ac.id. This method consists of five stages, namely: planning, analysis, design, implementation, and support. A Drupal core is used in the implementation of the information system in this research. The research result consists of two parts namely the information of pest and disease. The information of pest consists of the pest characteristics, indications, and controls. The disease information consists of disease characteristics, indications, and controls.

Judul: Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana), Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana
Abstrak: I reevaluated taxonomic of subgenus Papurana position from Halmahera based on morphological and molecular analyses. My results show that two separate species occur on the Halmahera Island, each nested within two distinct clades (hereafter papua clade and celebensis clade), one of which corresponds to H. moluccana (celebensis clade) and the other to an unidentified species (papua clade). By p-distance ranging from 6.9 to 11.5% on the 16S rRNA gene, the unidentified species (Hylarana sp.) is genetically different from all congeners of the papua clade. The Hylarana sp. can be distinguished from all congeners by following combination of charactes: vomer teeth in two oblique rows with narrow inter-vomer distance; snout rounded dorsally; dorsum with few scattered cone-shaped tubercles that are black with white tips; distinct skin folds (ridges) on the dorsal side of the thigh coinciding with dark brown cross bars; a marbled pattern on the ventral side of the thigh and yellowish groin. I also present new data for H. daemeli, H. volkerjane, and H. arfaki from the western region of Papua. Furthermore, I found that H. celebensis has numerous mtDNA lineages, indicating cryptic diversity within the celebensis clade. The discovery of two separate species on Halmahera necessitates more research into the biogeographic history of Hylarana in Northern Moluccas.
