In terms of geology, most areas in south of the Gunungkidul District in Central Java consist of the Wonosari formation limestone. The land is generally very dry and source of raw water is also difficult to reach. Findings on the existence of underground river in caves, however, indicate the potential amount of water within the area, especially in the eastern part of the Gunungkidul District. Although limited information available, some fishermen have discovered that Seropan cave contains fresh water source. This cave is situated at 65 m below the cliff. Initial exploration, which done using a multichannel resistivity method, confirmed the availability of freshwater in the cave and underground river. The isopach of cave depth is found in ranges of 80 200 m below the ground surface. The water of Seropan cave can be utilized by implementing pipeline or by drilling at the suggested point based on the interpretation results, i.e. 110o2223.6388 EL 8o42.874 SL.

Specimens identified as Oreonectes jiarongensis (Cypriniformes: Nemacheilidae) were collected from a karst cave in Jiarong Town and Banzhai Township, Libo County, Guizhou, China. Several lines of morphological and molecular evidence suggested that this species was similar to species of Oreonectes Günther 1868 and not closely related to species of Triplophysa Rendal, 1933. The anterior and posterior nostrils of 'Triplophysa' jiarongensis were separated by a short distance, and there was no secondary sexual dimorphism in male specimens. The Bayesian phylogenetic analysis based on cytochrome b recovered 'T.' jiarongensis in a well-supported clade with Oreonectes daqikongensis, O. shuilongensis, O. furcocaudalis and O. platycephalus, sister to the Triplophysa clade. In addition, the genetic distances between 'T.' jiarongensis and species of Oreonectes were low (O. daqikongensis: 0.114; O. shuilongensis: 0.106; O. platycephalus: 0.180), while distances to species of Triplophysa were higher (T. dorsalis: 0.233; T. yarkandensis: 0.282). Therefore, we reassign 'T.' jiarongensis to Oreonectes. Based on this result, it is now clear that species of both Oreonectes and Triplophysa inhabit the same underground river system in Guizhou. However, as species of Oreonectes are only known from the southern part of Guizhou, it may be that O. jiarongensis inhabits the most northerly part of the range of this genus.

The Kiskendo Cave System is a system that has many benefits, including as a tourist site and water source. One of the systems in the upstream of Kiskendo Cave is the Semar-Kiskendo Caves system. This system is estimated to greatly affect the condition of the Kiskendo cave system because it is connected to the allogenic river which contributes to recharge from outside Jonggrangan Karst Area. The purpose of this research was 1) to find out the characteristics of the Semar Cave cavities and 2) to analyze the connectivity and characteristics of cavities in the Semar - Kiskendo Caves system. This research employed a survey method by mapping the cave to answer the first problem and conducting a tracer test of underground river stream to answer the second problem. The results showed that the Semar Cave cavity that could be mapped was 158.2 meters long, the total volume of the cave was 1,220.6 m3, and the average diameter of the cave cavity was 2.8 meters. The results of second study using the tracer test showed the connection between Semar Cave and the underground river in Kiskendo Cave, and the cavities had a characteristic of a single conduit which was sufficiently developed.
