“…Location 2 epipedons form in the category of ochric epipedons. It is said that the epipedon is okric at this location because the results of the identification of the features and characteristics of the epipedon do not meet the seven epipedons considering the thin thickness of 18 cm and supported by a color value > 3 (bright) (Dengiz et al, 2012;Sitinjak et al, 2019;Ferdeanty et al, 2020). The light color in epipedon location 2 is bright because Corganic has a lower value than endopedon.…”

The total area of irrigated rice fields on the slopes of Mount Argopura is 21,420.02 hectares. Soil that experiences flooding will change the characteristics of the physical, chemical, and soil classification properties. The aim of the study was to examine the soil characteristics and classification system of paddy fields on the slopes of Mount Argpura. The research was conducted in July–September 2022 in paddy fields on the slopes of Mount Raung. Soil analysis in the laboratory of the Faculty of Agriculture, University of Jember This research uses a descriptive exploratory method through field surveys. Parameter research on the chemical-physical characteristics of soil and soil classification The research shows that the average rainfall of paddy fields at the foot of Mount Argopura is 2,275 mm per year with a standard deviation of 514 mm and a coefficient of variance of 23%. The morphological horizons of the genesis results in paddy fields are generally Apg, Adg, Bwg, and Cg. The USDA's classification of soil Hydraquentic Humaquepts (pedon 1), Typic Epiaquepts (pedon 2), Aeric Epiaquepts (pedon 3), Indonesian soil classification Gleisol molik (pedon 1), Gleisol eutric (pedon 2), and Gleisol eutric (pedon 3), according to WRB/FAO Molic epireductic Gleisol (Aphihumic) (pedon 1), ochric reductive gleysol (ochric, clayic) (pedon 2), and ochric siltic reductive gleysol (pedon 3).

“…Lereng Tengah Perbukitan Karst (TP5) memiliki tekstur tanah lempung dengan kedalaman tanah 40 cm dengan satu horizon A. Kesesuaian antara delineasi morfologi dan survei tanah pada lokasi kajian sangat akurat sehingga cukup baik untuk diaplikasikan pada zona transisi geologi atau geomorofologi. Hasil serupa juga diperoleh pada penelitian lainnya berupa terdapat hubungan dan kesesuaian antara morofologi dan karakteristik tanah pada setiap satuan bentuk lahan (Sitinjak et al, 2019;Noviyanto et al, 2020;Aji et al, 2020).…”

The transition zone of the Wonosari and Nglanggran Formation in Purwosari District has the characteristics of thick soil, steep slopes, and no outcrops. The different characteristics found in the Wonosari Formation Zone are characterized by polygonal karst formations with thin soil and limestone rocks, and the Nglanggran Formation in the form of thick soil, andesite rock outcrops, and steep slopes. Geomorphological mapping of the Nglanggran and Wonosari Formation can be done easily through morphological approaches and outcrops. Geomorphological mapping is quite difficult to do in the transition of the Wonosari and Nglanggran Formation because it does not have outcrops and is difficult to interpret from morphology. Soil geomorphological approach needs to be done to define landform units for areas that do not have outcrops dan difficult to interpret through morphology. The purpose of this study was to map the geomorphological distribution of soil characteristics in the geological transition zone. The methods used to identify landform units are morphological delineation and soil survey. The morphological delineation for landform units was obtained from aerial photographs. The results of the delineation of landforms from aerial photographs are detailed by soil surveys. The results of the delineation of landforms using aerial photography produce high resolution, smooth, and firm compared to other sources. The results of the delineation of landforms from aerial photos obtained two units of landforms, limestone karst hills, Wonosari formation and andesitic rocky hills, Nglanggran formation. There is a transitional transition zone in the TP7 soil sample with the color change from dark brown (karst) to light brown (old volcanic). The thickness of the soil in the old volcanic is more than 1 meter and deeper than the karst soil (< 60 cm). The transition zone has three soil horizons A, B, and B/C which are classified as more developed than the karst region (A and B horizons). The soil texture in old volcanic is clay and silt, while the dominant karst area is clay.

One of the sea turtle nesting habitats in Indonesia is located on the southern coast of Java Island. Bajul Mati and Jolangkung coastal areas, Malang Regency are locations of sea turtle nesting that exist in Java Island and already had conservation efforts along with it. The data inventories are nesting area data gathering and the result of sea turtle nesting which is aimed to develop conservation efforts. The purpose of this research is to integrate participation maps with aerial photographs and to identify potentials and challenges of the eco-tourism activity in the coastal area of Malang Regency. The data used are participation maps nesting point, aerial photographs result, and plotting point of nesting. The method in this research includes digital participation maps making which is then integrated with aerial photographs result and plotting point of nesting. The result of this research is integration maps of participation with aerial photographs which show in coastal area zonation as the habitat of sea turtle nesting and conservation area zonation. The conservation area zoning is one form of education for the ecotourism approach. The challenge of eco-tourism activity is to grow the regional government’s trust and commitment to join and participate in sustainable eco-tourism.
