Abstract. Yulita KS, Atikah TD, Wardani W, Susila. 2020. Unraveling genetic variations of Dalbergia latifolia (Fabaceae) from Yogyakarta and Lombok Island, Indonesia. Biodiversitas 21: 833-841. Dalbergia latifolia Roxb. (Fabaceae) or sonokeling is a timber species extracted for its beautiful heartwood used mainly for musical instruments. D. latifolia was listed in Appendix 2 of CITES since 1997, and the demand for its timber is increasing. The species is considered vulnerable (VU A1cd ver 2.3) to extinction according to the IUCN Red List, while cultivations were mainly done from a root cutting. To anticipate the further loss of population size while maintaining sustainable use of the species, it is essential to evaluate the genetic diversity since the genetic diversity level could serve as an indicator of plant adaptability to its environment. This present study was the first to report the genetic diversity of five populations of D. latifolia from Yogyakarta and Lombok Island, West Nusa Tenggara, Indonesia. Ten combinations of Sequence Random Amplified Polymorphism (SRAP) primers were used to amplify 48 samples of D. latifolia from five populations in Yogyakarta and Lombok Island. The 137 SRAP loci were used for a cluster, and population genetic analysis, with mean NPL, was of 13.6/locus, PLP of 56.18%, H of 0.16, and PIC for all population was of 0.28. The lowest gene diversity (H = 0.11) was observed in population WL 1 of Lombok Island, while the highest (H = 0.20) was recorded for population KP of Yogyakarta. The Yogyakarta and Lombok populations were genetically structured at a medium level (Gst = 0.27), with low genetic distance (0.0310-0.1281), and a moderate level of variation observed among individual trees (ca. 0.5 coefficient similarity). The results of this present study were expected to provide necessary information on further research of D. latifolia from Indonesia to support the sustainable use of D. latifolia in Indonesia and the preservation of this species.

In today's era, humans prioritize systems and business, but along with Islamic progress, Sharia-based economy and business are now starting to develop.  To meet daily needs, transportation is currently the urgent need for everyone. This is because transportation can support all activities in the community. This type of transportation too affects the rotation of activities that can be utilized in the economic sector, delivery of goods or services, and passenger transportation. This study aims to analyze the position of online ojek based on the perspective of Islamic law. Looking at the current development of the Islamic economy, many do not follow Islamic law in economic and business development. In this case, a compelling case for research is the development of the online transportation business. This study uses the normative juridical method. In normative research, to obtain data, you must use secondary data sources or library data and abuse laws and Hadith, or Al'qur'an as a writing reference.  So, from the discussion, we can see that online transportation service companies have succeeded in achieving Sharia business principles. This is all proven by economic progress and has created community welfare.
