Ariadi Z, Nurwahyudi MA, Efriandi E, Defriyanti WT. 2022. The determination of horticultural clusters using superior commodity approach in South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 954-962. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The implementation of horticultural development by regional governments in South Sumatra still has various obstacles, such as a large number of production centers with the same commodity, production adequacy, and budget constraints. Therefore, it is important to focus on the development of horticultural clusters. This study aimed to determine the horticultural clusters using the superior commodity approach in South Sumatra. We use horticultural production data series as data sources. We also use Location Quotient (LQ), Shift Share analysis, and Klassen Typology as analysis methods. The results showed that each horticultural commodity tested had a comparative advantage and was spread over the districts/cities. The same conditions also occurred for competitive advantage. Another result showed that only 8 (eight) commodities simultaneously had comparative and competitive advantages in a district/city. Thus, it was determined that the district/city area where the two advantages are located is designated as a horticultural cluster. These clusters were the shallot clusters in Ogan Komering Ulu and Pagar Alam, the chili cluster in Ogan Komering Ilir, the potato cluster in Pagaralam, the duku clusters in Musi Rawas Utara, the durian cluster in Musi Rawas, Ogan Komering Ulu Selatan, and Musi Rawas Utara, the citrus clusters in Ogan Komering Ulu, Musi Rawas Utara, and Pagar Alam. mango cluster in Musi Rawas Utara and banana cluster in Muara Enim.

Efriandi E, Nurwahyudi MA, Ariadi Z, Karenina T, Defriyanti WT.  2022. Relationship between some physical properties of soil inceptisol post soil mining. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 1067-1072.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Research to know and observes change of morphology after done soil mining for brick industry. The purpose of this study is to find out and observe changes in the physical properties of the soil after taah mining for the brick industry.Research is done by observing 4 soil profile that is (1) soil that is not is mined (control); (2) soil which have been mined and leaved more than 10 years; (3) soil which have been mined and leaved ± 5 year; (4) soil which have been mined and leaved between 1-3 years. Inceptisol soil has limited physical properties for the development of the root system and soil roots, has a thin effective depth for tillage, has a larger density due to some of the pores filled with dust particles. Based on the distribution of each soil order on the earth's surface, inceptisols have an area of about 15% of the earth's surface area. Classified as fertile land for agricultural land. Result of research indicates that Inceptisol experience change of morphology soil colour, structure, consistency, root, horizon boundary. Inceptisol which has been mined for brick base material experiences change of morphology and soil physical properties. The need of doing of research that is further about land rehabilitation technique so that serve the purpose of consideration in doing repair of area ex-mined.
