No full textABSTRAK Labib, Mohammad Ainul. 2013. Karakteristik Morfologi Lorong Sistem Perguaan Bagus-Jebrot Di Desa Mentaraman Kecamatan Donomulyo. Skripsi, Jurusan Geografi FIS Universitas Negeri Malang. Pembimbing: (1) Drs. Sudarno Herlambang, M.Si (II) Drs. J.P. Buranda M.Si Kata kunci: Karakteristik, Morfologi lorong, Sistem Perguaan Malang Selatan yang sebagai besar berupa daerah pantai sangat sesuai digunakan sebagai kawasan pariwisata. Namun pengembangan kawasan pantai di Malang Selatan masih sangat kurang sehingga dalam pengembangannya masih terhambat. Dengan temuan yang ada di dalam gua dapat meningkatkan kualitas dan kuantitas pengunjung yang ada. Temuan-temuan tersebut berupa ornamen gua dan bentukan lorong gua. Sistem perguaan Bagus-Jebrot tidak hanya sebatas penelusuran gua saja, namun dapat pula dijadikan sebagai kawasan ekowisata mengingat sistem perguaan ini dapat menunjang pariwisata di Pantai Jonggring Salaka. Sistem perguaan ini terdapat keberagaman ornament yang ada di dalam gua tersebut. Keberagaman tersebut dapat terlihat dari lorong sistem perguaan Bagus-Jebrot. Dengan demikian terlihat jelas terdapat keberagaman yang ada pada lorong gua berupa ornamen, ukuran dan karakteristik bentukan lorong Gua Bagus dan Gua Jebrot yang dapat menunjang kawasan ekowisata di gua tersebut. Namun, permasalahan data dan informasi mengenai keberagaman ornamen, ukuran, dan karakteristik bentukan lorong gua pada sistem perguaan Bagus-Jebrot masih sangat terbatas. Penelitian ini bertujuan mendeskiripsikan karakteristik morfologi lorong Sistem Perguaan Bagus-Jebrot. Diskripsi bentukan lorong-lorong gua, perhitungan mengenai lorong gua serta sebaran ornament yang ada di Gua Bagus-Jebrot Metode penelitian yang digunakan adalah survey. Berdasarkan jenisnya penelitian ini kualitatif dengan analisis spasial dan deskriptif. Sampel penelitian di dalam gua diambil pada setiap stasiun, sampel yang akan diambil meliputi tinggi lorong, lebar lorong pada setiap stasiun, kedalaman/kemiringan, ornamen gua dan panjang lorong. Hasil penelitian menunjukkan Sistem Perguaan Bagus-Jebrot merupakan gabungan dari Gua Bagus dan Gua Jebrot dengan enterence berupa lorong horizontal yang berada di lembahan. Elemen lorong yang dimiliki Sistem Perguaan Bagus-Jebrot berupa Single Conduit Passage dengan jenis elemen lorong Angulate Passage. Chamber yang terdapat pada Sistem Perguaan Bagus-Jebrot terdapat pada Gua Bagus dengan ketinggian 6,42 m dan 4 m. Sistem Perguaan Bagus-Jebrot berdasarkan klasifikasi Palmer (2003) memiliki pola morfologi lorong Curvilinear Branchwork. Berdasarkan klasifikasi Sweeting (1972) Sistem Perguaan Bagus-Jebrot merupakan gua yang termasuk ke dalam tipe Vadose Cave. Bedasarkan kondisi hidrologis lorong, Sistem Perguaan Bagus-Jebrot dapat dibagi menjadi 2 segmen yaitu lorong fosil dan vadose. Morfometri lorong Sistem Perguaan Bagus-Jebrot memiliki panjang Gua Bagus yang terpetakan 123,06 m dan Gua Jebrot yang terpetakan 289,73 m. Luas lorong Gua Bagus 548,54 m² dan Gua Jebrot 527,84 m². Volume Gua Bagus 4083,82 m³ dan Gua Jebrot 3575,43 m³. Luas area Gua Bagus 6347,43 m² dan Gua Jebrot 16937,62 m². volume spesifik Gua Bagus 33,19 m³/m dan 12,34 m³/m, kerapatan jaringan lorong Gua Bagus 51,58 m/m² dan Gua Jebrot 58,46 m/m², cakupan area Gua Bagus dan gua Jebrot sebesar 3,1%. Ornamen yang dapat ditemui di Gua Bagus yaitu Stalagmite, Stalactite, Coulumn/pillar, Flowstone, Gourdam, dan Soda straw. Gua Jebrot yaitu stalagtit, flowstone, dan gourdam
THE EFFECTIVENESS OF ROUNDTABLE TECHNIQUE ON STUDENT’S WRITING SKILLS IN DESCRIPTIVE TEXT
No full textThis research aimed to assess the effectiveness of implementing the roundtable technique in enhancing descriptive writing skills among eighth-grade students at SMP Simanjaya Lamongan. The research utilized a pre-experimental one-group pretest-posttest design. Data analysis involved the application of a paired sample t-test to ascertain the presence of a significant effect before and after the intervention. This research included a sample of 30 students from the eighth grade at SMP Simanjaya Lamongan. The findings of the research indicated a notable improvement in students' writing skills when employing the roundtable technique. This was evident in the average scores obtained by students on both the pretest and posttest. The mean score increased from 73.60 during the pretest to 83.03 in the posttest. The researcher then conducted a paired sample t-test to address the research question. The results of the t-test analysis revealed that the p-value (probability value) was below the significance level α (0.00 < 0.05). Consequently, the null hypothesis (Ho), asserting no significant effect of the roundtable technique on students' descriptive writing skills, was rejected. The acceptance of the alternative hypothesis led to the conclusion that the roundtable technique had a significant positive effect on the students' writing skills in producing descriptive texts
The Effect of Game-Based Learning Through the Snake and Ladder Game on Students’ Speaking Skills
No full textSpeaking was crucial skill to be learnt by student in order to talk with others from around the world. Students would need to rehearse to be able to express their ideas in English. The students’ Speaking skill was developed in the classroom when they have English class though in daily activities, they did not speak English. It made speaking as one of the most challenging things for students to grasp. The use of a good teaching method or media was really important in the teaching speaking process. The snake and ladder game was used as a medium by the researcher. This research was using experimental research with pre-experimental design (one group pretest-posttest). The data itself was analysed by using statistical through SPSS program. The participants of the research were the eleventh grades students of MA Falahiyah Lamongan. The data showed the students’ basic speaking skill of eleventh grades students in MA Falahiyah Lamongan were poor, because most of the students score were under the minimum score criteria. There were only 13% students passed the test. After getting the treatment, the result of the finding of post-test, the data showed the students’ speaking skill were improved because most of the students got enough score to complete the test. The result of the calcutaion of paired sample t-test with the sign (2 tailed) the result was .000, it was lower than 0.05 as level of significant. It means that the use of game-based learning through the snake and ladder game to teach speaking gave significant effect on students’ speaking skills

Karakterisasi Lorong Gua di Geosite Gua Pindul, Geopark Gunungsewu, Kabupaten Gunungkidul
No full textGeopark Gunungsewu memiliki Geosite yang tersebar di Kabupaten Pacitan, Wonogiri, dan Gunungkidul. Salah satu geosite yang berkembang dengan cepat salah satunya terdapat di Kabupaten Gunungkidul, yaitu geosite Gua Pindul. Kajian ini bertujuan untuk menganalisis karakteristik lorong gua dan faktor-faktor yang mempengaruhi pembentukannya (speleogenesis) pada beberapa gua di geosite Gua Pindul dan sekitarnya. Metode yang digunakan yaitu dengan survei lapangan dengan melakukan pemetaan gua dan menganalisis bentuk lorong gua di lokasi kajian. Hasil kajian memperlihatkan pola lorong gua berupa curvilinear branchwork, sinuous passage, dan linier passage. Kenampakan lorong gua dipengaruhi oleh adanya kondisi tidak tertekan dan adanya air meteorik yang melarutkan batugamping, sehingga membentuk elliptical tube, keyhole, gorge-shaped passage, cupola, ceiling half tube, solutions notch, potholes, dan solutions pocket. Selain itu, adanya pengaruh kontrol struktural mempengaruhi arah perkembangan lorong gua sedangkan bentukan akibat adanya kontrol struktural berupa joint control passage, shaft, dan canyon
Hydrogeology of Mangsri Cave, Gunungsewu Karst Area, Java Island, Indonesia
No full textThe Gunungsewu karst area is not only known for its unique landscape but also its recurring drought events. To meet the water supply, the local population utilizes several water potentials, namely doline pond, spring, and underground river. This study was designed to analyze the hydrogeological conditions of Mbangsri Cave, following its accidental discovery by the community at the end of 2018. The hydrogeological analysis was conducted by geological surveys, which consisted of rocks collection and structural measurements, cave mapping, and recharge area delineation based on remote sensing images acquired by unmanned aerial vehicles. The results showed that Mbangsri Cave, in the hydrogeological perspective, had low water resources potential. It is believed to be the result of (1) relatively small catchment area, (2) a fault in the southern part of Mbangsri Cave, creating a small groundwater basin, and (3) the thin epikarst layer, limiting the water storage
