Abstract

Desa Limbasari secara geografis terletak di Kecamatan Bobotsari Kabupaten Purbalingga. Desa Limbasari merupakan salah satu desa wisata yang baru di Kabupaten Purbalingga. Desa ini mempunyai potensi yang besar untuk dikembangkan sebagai destinasi wisata dalam segi wisata kebumian dan geoheritage. Daya tarik wisata yang ada berupa River Tubing, landscape pegunungan batuan gunung api yang terdapat batu jasper hijau “nogo sui”, dan situs kebudayaan prasejarah. Di samping itu keunikan budaya serta sejarah masyarakat juga menjadi daya tarik bagi masyarakat perkotaan. Tujuan dari pengabdian masyarakat adalah mengulas kelayakan geosite dan geomorphosite di Desa Limbasari sebagai sebuah solusi bagaimana memanfaatkan kekayaan geologi beserta berbagai dinamikanya untuk kegiatan wisata edukasi dan ekonomi yang berwawasan lingkungan. Metode yang digunakan adalah pemetaan potensi geologi sebagai kawasan wisata, inventarisasi pada lokasi yang mempunyai cagar budaya dan sejarah serta wawancara dengan pihak terkait dan studi literatur. Dari hasil kelayakan di kawasan wisata Limbasari mempunyai nilai kelayakan antara 47.5% - 73.5%. Dengan demikian, Kawasan Desa Wisata Limbasari, Kabupaten Purbalingga layak menjadi objek geowisata dengan aspek penilaian didasarkan pada nilai kuantifikasi berbagai keindahan antara alam dan proses geologi yang mengontrol terbentuknya obyek geowisata tersebut.Limbasari Village is geographically located in Bobotsari Subdistrict, Purbalingga Regency. Limbasari Village is one of the new tourism villages in Purbalingga Regency. This village has great potential to be developed as a tourist destination in terms of earth tourism and geoheritage. The tourist attractions are River Tubing, mountainous volcanic mountain landscape with green jasper stone "nogo sui", and prehistoric cultural sites. In addition, the cultural and historical uniqueness of the community is also an attraction for urban communities. The purpose of this study is to review the potential of Geotourism and geoheritage in the Village of Limbasari as a solution to how to utilize the rich geological and cultural sites along with various dynamics for educational activities that are environmentally friendly education and economy. The method used in this study is the mapping of geological potential as a tourist area, an inventory of locations that have cultural and historical reserves as well as interviews with relevant parties and literature studies. From the results of research in the tourist area Limbasari has a feasibility value between 47.5% - 73.5%. Thus, the Limbasari Tourism Village Area, Purbalingga Regency deserves to be a geotourism object with the assessment aspect based on the quantification value of various beauties between nature and the geological process that controls the formation of the geotourism object.

Abstract

Batuan silisiklastik berumur Trias yaitu Formasi Kanikeh, tersebar di Pulau Seram hingga Pulau Kesui dan Teor dari Maluku hingga Maluku Tenggara. Formasi Kanikeh telah lama dikenal memiliki karakteristik batuan induk yang baik. Pemahaman tentang Formasi Kanikeh masih minim, interpretasi lingkungan pengendapan dan korelasi stratigrafi masih ada perbedaan. Tujuan penelitian ini adalah mendapatkan hasil interpretasi lingkungan pengendapan berdasarkan data terbaru. Metode yang digunakan dalam penelitian ini adalah pengukuran penampang stratigrafi pada empat lintasan pengamatan di daerah Seram Bagian Timur dengan menggunakan pendekatan analisis litofasies dan asosiasi fasies. Hasil dari penelitian ini menunjukkan adanya 9 litofasies, yaitu: Litofasies Batupasir Konglomeratan (Sg); Litofasies Batupasir Lapisan Silangsiur Mangkok (Sp); Litofasies Batupasir Bioturbasi (Sb); Litofasies Batupasir Karbonan (Sc); Litofasies Batupasir Bergelombang (Sw); Litofasies Batupasir Flasser (Sf); Litofasies Batupasir Laminasi Sejajar (Sh); Litofasies Batulumpur Lenticular (Fl); Litofasies Batulumpur Berlapis (Fsc). Deskripsi litofasies tersebut termasuk ke dalam suatu sistem pengendapan pasang-surut (intertidal) yaitu tidal channel, tidal sand flat, tidal sand-mud mixed flat, dan tidal mudflat. Formasi Kanikeh terendapkan dengan sistem pengendapan batuan silisiklastik yang dipengaruhi oleh arus pasang-surut pada lingkungan pengendapan transisi. ABSTRACT - Facies and depositional environment of Kanikeh Formation, Bula Basin, Maluku. The Triassic siliciclastic rocks, Kanikeh Formation are spread across Seram, Kesui, and Teor Island from Molucca to Southeast Molucca. The Kanikeh formation has been known as an excellent source rock. However, its interpretation of the depositional environment and stratigraphic correlation are still poorly understood. This study aims to give a better understanding of the depositional environment. This study consists of Lithofacies descriptions and facies associations of four stratigraphy measuring sections in Eastern Seram Island. The results of this study indicate that there are 9 lithofacies, including conglomeratic sandstone (Sc); Through cross bed sandstone (Sp); Bioturbated sandstone (Sb); Carboniferous sandstone (Sc); Wavy Sandstone (Sw); Flasser Sandstone (Sf); parallel laminated sandstone (Sh); lenticular mudstone (Fl); dan laminated mudstone (Fsc). The lithofacies description is included in four facies associations which are included in a tidal deposition system (intertidal) there are tidal channels, tidal sand flat, tidal sand-mud mixed flat, dan tidal mudflat. Based on the results Kanikeh Formation is deposited with a siliciclastic deposition system influenced by tidal currents within transition deposition environments.

Abstract

This study undertakes a comprehensive analysis of the geological conditions within a specific region, with a dual objective. Firstly, it aims to detail the geophysical attributes, structural aspects, and formation processes of the region. Secondly, it strives to establish a connection between the provenance, or origin, of the sedimentary materials in the region and its geological characteristics. The primary subjects of the research are the Waturanda and Penosogan Formations. These formations were selected due to their unique geological properties that offer insights into the geological history of the region. The primary method employed in the study was petrographic analysis. This technique, involving a microscopic examination of rocks, facilitated a detailed investigation into the rock samples from both formations, highlighting their mineralogical constitution and overall textures. The study also involved a thorough examination of the original rock or parent material of the Waturanda and Penosogan Formations. This analysis provided important information about their inherent geological attributes and formation processes. One of the key findings was the identification of the tectonic environment in which these formations were developed. The study revealed that the tectonic setting was a magmatic arc, specifically a dissected arc. This significant insight into the geological conditions has profound implications for understanding the geological evolution and history of the region, thereby enriching our knowledge of Earth's dynamic geological processes.

Abstract

Gunung Slamet adalah gunungapi bertipe stratovulkano yang terletak di Provinsi Jawa Tengah. Gunung Slamet secara umum dibagi menjadi dua bagian yaitu Slamet Tua di bagian barat dan Slamet Muda di bagian timur. Penelitian geologi terdahulu hanya berfokus pada studi tentang petrologi dan geokimia batuan di Gunung Slamet. Studi ini membandingkan kondisi geomorfologi, petrologi, bencana geologi hingga geowisata Gunung Slamet Tua dan Gunung Slamet Muda dengan menggunakan metode citra satelit dan membandingkan data-data dari peneliti terdahulu. Secara geomorfologi Gunung Slamet Tua memiliki morfologi lebih curam dengan lembah yang dalam dan terjal kenampakan tekstur citra satelit lebih terlihat kasar jika dibanding Gunung Slamet Muda di sisi timur yang memiliki tekstur citra satelit yang lebih halus dengan lembah yang tidak terlalu dalam dan pada sisi barat daya Gunung Slamet terdapat morfologi yang disebut Lembah Guci. Slamet Tua memiliki komposisi batuan andesit basalt, pumice endapan piroklastik aliran, piroklastik jatuan dan piroklastik surge dengan komposisi SiO2 lebih tinggi 52,3 – 63,9 wt.%, dan Lembah Guci memiliki komposisi SiO2 yang sama dengan Slamet Muda yaitu 48,5 – 54,1 wt.%. Geowisata di Gunung Slamet terdapat beberapa air terjun baik di Gunung Slamet Tua maupun Gunung Slamet Muda, ada juga wisata berupa manifestasi air panas di Pancuran 7 Kabupaten Banyumas, dan Guci Kabupaten Tegal. Gunung Slamet memiliki tiga zona rawan bencana geologi yaitu zona I, zona II dan zona III. Lembah Guci memiliki ancama bahaya piroklastik aliran dan berada di zona bahaya I dan II.
