Berdasarkan statistik BNPB, Jawa Tengah menjadi Provinsi dengan bencana longsor terbanyak di Indonesia sepanjang tahun 2021–2023 sebanyak 1283 peristiwa, dengan 427 di antaranya terjadi di Kebumen. Pada Kampus Lapangan Geologi Karangsambung, Kab. Kebumen, Jawa Tengah sejumlah lahan telah ditimbun tanah untuk rencana pembangunan dengan longsoran rotasi yang pernah terjadi. Oleh karena itu, dilakukan identifikasi potensi longsor beserta geologinya di daerah Karangsambung pada area timbunan tanah baru. Penelitian ini melibatkan studi lapangan dengan metode geolistrik resistivitas dan data SPT untuk mengetahui kekuatan daya dukung tanah. Penelitian mencakup enam lintasan sepanjang 195–245 meter dengan spasi elektroda 5 meter dan konfigurasi Wenner-Schlumberger. Keluaran yang diperoleh berupa penampang resistivitas 2D yang dikorelasikan dengan data SPT, plan map 3D, serta model resistivitas 3D. Hasil penampang resistivitas 2D menunjukkan bahwa terdapat zona resistivitas tinggi 270–13.293 Ωm di daerah timur laut penelitian. Zona resistivitas tinggi ini merupakan rekahan batulempung selebar 5–13 meter di permukaan dengan ketebalan 10–15 meter yang di bawahnya merupakan intrusi batu andesit. Selain itu umumnya daerah penelitian terdiri atas lempung lanauan padat di permukaan dengan ketebalan 3–33 meter dan resistivitas 0,5–90 Ωm, serta lempung pasiran yang sangat padat di bawahnya dengan ketebalan lebih dari 15 meter dan resistivitas 0,01–30 Ωm. Berdasarkan hasil tersebut terdapat potensi longsor di timur laut daerah penelitian yang melewati lintasan LKR01, LKR02, dan LKR03, tepatnya pada zona resistivitas tinggi. Keberadaan potensi longsor ini diharapkan dapat menjadi acuan terkait pengawasan pembangunan di Kampus Lapangan Geologi Karangsambung. ...... Based on BNPB statistics, Central Java is the province with the most landslide disasters in Indonesia throughout 2021-2023 with 1283 events, 427 of which occurred in Kebumen. At the Karangsambung Geological Field Campus, Kebumen Regency, Central Java, a number of lands have been stockpiled for development plans with rotational landslides that have occurred. Therefore, an identification of landslide potential and its geology in Karangsambung area in the area of new landfill was conducted. This research involved field study using geo-electrical resistivity method and SPT data to determine the bearing capacity of the soil. The research included six passes along 195-245 meters with 5 meters electrode spacing and Wenner-Schlumberger configuration. The output is 2D resistivity cross section correlated with SPT data, 3D plan map, and 3D resistivity model. The 2D resistivity cross section results show that there is a high resistivity zone of 270-13,293 Ωm in the northeast area of the study. This high resistivity zone is a fractured claystone 5-13 meters wide at the surface with a thickness of 10-15 meters under which is an andesite intrusion. In addition, the study area generally consists of dense silt loam at the surface with a thickness of 3-33 meters and a resistivity of 0.5-90 Ωm, and very dense passive loam underneath with a thickness of more than 15 meters and a resistivity of 0.01-30 Ωm. Based on these results, there is a potential for landslides in the northeast of the research area that passes through the LKR01, LKR02, and LKR03 tracks, precisely in the high resistivity zone. The existence of this landslide potential is expected to be a reference related to development supervision in Karangsambung Geological Field Campus.

ABSTRACT
Marasmiellus is a tropical and subtropical genus which consists of more than 400 species. The genus plays important roles in ecosystem as a decomposer, and not many information on its economic value. Several monographs of the genus have been published based on morphological data from several tropical forests (neotropics, Africa, Srilanka), and no report on the Indonesian Marasmiellus. At present, taxonomic problem occurs in the genus related to the position of Marasmiellus juniperinus as a type genus in the phylogenetic tree based on Internal Transcribed Spacer (ITS) region. Marasmiellus juniperinus nested into different clade from other Marasmiellus species, and it was clustered in Gymnopus clade. Since Marasmiellus has never been reported from Indonesia and the taxonomic problem occurs at the genus, thus the objectives of this study are 1) To describe the species of Marasmiellus found in Java and Bali; 2) To provide an identification key to sections and species; 3) To analyse the phylogenetic relationship within the genus Marasmiellus in Java and Bali based on morphological and molecular characters performed by Maximum Parsimony method; 4) To clarify the relationship of the genus Marasmiellus and M. juniperinus to its closely related genera with inclusion of more Marasmiellus spp. based on ITS region of rDNA sequence data; and 5) To describe novel species of Marasmiellus based on morphological and molecular data. Java and Bali were chosen as research sites in this study due to several reasons. First, historically most of Indonesian reported agarics were collected from Java, particularly from Mount Gede-Pangrango, Cibodas and Bogor Botanical Gardens. Second, forest degradation is going rapidly in Java and Bali. As a result Indonesia is loosing habitats of Marasmiellus. This study was divided into three topics according to the purposes of this study. The first topic entitled Species of Marasmiellus in Java and Bali. The study was carried out in Herbarium Bogoriense, The Botany Division, Research Center for Biology, The Indonesian Institute of Sciences (LIPI). Herbarium materials are kept in Herbarium Bogoriense (BO) and Harry D. Thiers Herbarium, San Francisco State University (SFSU), SF, CA, USA. Materials used in this research were collected in 1998-2010 from 10 different locations in Java and Bali which consisted of 22 sites. A representative material of Marasmiellus juniperinus, as a type genus, was borrowed from the Herbarium of the University of Tennessee, Knoxville, Tennessee, USA (TENN). The identification results revealed that there were 35 known species; one species as a new combination; 17 undescribed species. Those 35 species consist of 25 species of Marasmiellus found in Java, 7 species found in Bali, and 3 species found both in Java and Bali. All described species were treated based on infrageneric classification of Singer (1973) which divided the genus into 10 sections based on morphological characters. Based on Singer?s infrageneric classification Marasmiellus in Java and Bali belonged to 5 sections, i.e sect. Marasmiellus, sect. Rameales, sect. Dealbati, sect. Candidi, and sect. Stenophylloides. The second topic entitled Phylogenetic study of the genus Marasmiellus based on morphological and molecular analysis. Thirty five morphological characters of 37 taxa were scored manually for phylogenetic analysis based on morphological characters. Those taxa consisted of 35 species of Marasmiellus in Java and Bali found (topic 1), a type species of Marasmiellus (M. juniperinus), and Crinipellis brunneipurpurea as an outgroup. Matrix data was analyzed by Phylogenetic Analysis Using Parsimony (PAUP) program. The topology of phylogenetic tree based on morphological data was compared to topology of phylogenetic tree based on molecular data. The phylogenetic tree based on morphological and molecular characters showed that Marasmiellus spp. were divided into four major clades. Each clade consisted of several Singer?s sections. This result indicated that the sections within Singer?s infrageneric classification were polyphyletic. Morphological and molecular phylogenies resulted in this study did not support traditional classification, i.e. Singer?s classification of Marasmiellus. The phylogenetic relationship of Marasmiellus taxa, Gymnopus and its closely related genera were analyzed using molecular data of ITS rDNA. Forty one sequences based on ITS region representing of 36 species of Marasmiellus were used for phylogenetic analysis. Nine sequences of Marasmiellus were generated from this study, and 32 sequences were obtained from the international DNA database (GenBank). The phylogenetic tree showed that Marasmiellus taxa were divided into 4 clades. The taxa of Marasmiellus and Gymnopus were clustered together in three of four clades. The type species, Marasmiellus juniperinus was located within the same clade as Gymnopus fusipes. This result indicated that the genus Marasmiellus was polyphyletic. The third topic entitled Description of a novel species, Marasmiellus javanicus, based on morphological and molecular analysis. Marasmiellus javanicus is one of the 17 new species in this study, and it was described by using the integrated morphological and molecular data. Marasmiellus javanicus was described as a new species based on 5 specimens found in Bogor Botanical Garden, West Java. Morphologically it was similar to M. hondurensis (Murrill) Singer which was collected from Belice in 1906 by Peck (Singer 1973). The characters similarities of M. javanicus and M. hondurensis were off-white, same size of width, convex with flattened disc of pileus; subdistant lamellae; tomentose and insititious stipe; cutis with diverticulate of pileipellis, and presence of stipe vesture. Marasmiellus hondurensis was different from M. javanicus in having longer stipe (6?22 mm diam), fusoid basidiospores, Rotalis-type of cheilocystidia, and M. hondurensis was found on dicotyledon plant. At present, there is no sequence based on ITS rDNA of M. hondurensis. Thus, genetically M. hondurensis was unable to be compared to M. javanicus. To know the closest species of M. javanicus, phylogenetic tree of Marasmiellus was constructed. Phylogenetic tree showed that the most closely related species to M. javanicus was M. mesosporus. Marasmiellus javanicus and M. mesosporus have ITS rDNA 94% sequence similarity. They differ in 27 nucleotides which were 7 insertion and deletion, and 24 of substitution (A↔G=11, C↔T=13). This study showed that integrated morphological and molecular data are required to identify the Marasmiellus.
