MORPHOLOGY AND CLASSIFICATION OF SOIL IN VARIOUS KINDS OF KARST SUBLANDFORMS IN THE WONOSARI FORMATION, GEDANGAN DISTRICT, MALANG REGENCY • Journal title: MORPHOLOGY AND CLASSIFICATION OF SOIL IN VARIOUS KINDS OF KARST SUB-LANDFORMS IN THE WONOSARI FORMATION, GEDANGAN DISTRICT, MALANG REGENCY • Author's name: Andre E.S. Sitinjak, Mochtar Lutfi Rayes, Christanti Agustina • Journal Name: Journal of Land and Land Resources • Year and Page: 2019, Vol. 6 No.1:1055-1064 • Research Objectives: This study aims to evaluate the morphological characteristics and soil classification in various kinds of karst sub-landforms in the Wonosari Formation, Gedangan District, Malang Regency. • Research Hypothesis:• Research Framework: This study uses a quantitative descriptive approach with field and laboratory survey techniques. • Thought Frame: This study was conducted to obtain a better understanding of the morphological characteristics and soil classification in different karst sub-landforms in the study area. • Population and Sample: The population in this study is soil in various kinds of karst sub-landforms in the Wonosari Formation, Gedangan District, Malang Regency. Samples were taken using the purposive sampling method by considering morphological and vegetation variations in each sublandform. • Sampling Method: Identification of soil morphology to obtain soil range data was carried out using minipits at 54 observation points and determination of soil morphology and classification in detail identified on 6 (six) representative pedons, namely P1 sub-landform puthuk karst on karst hills, P2, P3 and P4 sub-landform of karst backs on karst hills, P5 karst reclamation on karst plains and P6 karst reclamation on karst hills. Representative pedon was selected from the similarity of characteristics and soil classification of 54 minipits spread across the research site. • Research Methods: • • • • The research methods used are field and laboratory survey techniques, which include observation of soil morphology, physical and chemical analysis of soil, and statistical analysis. Results and Discussion: The results showed that there were significant differences in morphological characteristics and soil classification in various sub-landforms of karst in the Wonosari Formation, Gedangan District, Malang Regency. This is due to differences in the influence of geological and geomorphological processes on the formation of sub-landforms of karst, as well as other biotic and abiotic factors. Conclusion: Based on the results of the study, it can be concluded that the morphological characteristics and soil classification in karst sub-landforms vary depending on the influence of geological processes, geomorphology, and other biotic and abiotic factors. Advantages: This study provides a better understanding of the morphological characteristics and soil classification in different karst sub-landforms in the Wonosari Formation, Gedangan District, Malang Regency, so that it can help in more effective land management and development. Cons: There are no hypotheses in the journal.
