Studi Geologi Dan Logam Tanah Jarang (RE) Daerah Air Gegas, Bangka Selatan

Tanah Jarang (RE) merupakan komoditas yang sangat berharga baik untuk industri maupun untuk PLTN. Secara kimia RE terdapat dalam dalam ikatan fosfat (P) yang pada mineral monasit, xenotim, zirkon berasosiasi dengan mineral kasiterit, magnetit, ilmenit, rutil, anatas, apatit, kuarsa dan feldspar terdapat dalam endapan pasir aluvial sungai atau plaser pantai. Endapan RE dalam monasit, zirkon, xenotim di daerah Air Gegas, Bangka Selatan merupakan endapan aluvial sungai yang mempunyai kemudahan dalam eksplorasi dan penambangan. Secara geologi mineral monasit, xenotim, zirkon berasal dari Granit Klabat yang berumur Jura. Metode yang dilakukan adalah pengamatan geologi, pengukuran radioaktivitas, pengambilan contoh, analisis laboratorium (mikroskopis dan XRF). Hasil penelitian menunjukkan bahwa geologi daerah Air Gegas Formasi Tanjung Genting terdiri dari batupasir, lempung (Trias Awal), Granit Klabat (Jura Akhir–Trias Awal) dan endapan Aluvial (Kuarter). Endapan aluvial mengandung monasit 0,071–3,574 %, zirkon 0,172–10,376 %, xenotim 0,15–3,023 % dari berat MB 10,73–168,072 gram. Keberadaan logam tanah jarang (RE) berasal dari mineral monasit, xenotim, zirkon yang bersumber dari batuan Granit Klabat. Sebaran tanah jarang (RE) terdistribusi pada bagian timur daerah penelitian yang menempati lembah sungai. Rare Earth (RE) is a valuable commodity both for industry and for the Nuclear Power Plant (NPP). In RE chemical bonds present in the phosphate (P) are the mineral monazite, xenotime, zircon minerals associated with cassiterite, magnetite, ilmenite, rutile, anatase, apatite, quartz and feldspar sand deposits are found in alluvial river or beach placer. RE deposits in monazite, zircon, xenotime in the Air Gegas of South Bangka area is an alluvial river that has the ease of exploration and mining. Geologically, monazite, xenotime and zircon minerals are from Klabat Granite aged Jurassic. The used method are the observation of geology, radioactivity measurement, sampling, laboratory analysis (microscopic and XRF). Results showed that the geology of the area Air Gegas of Tanjung Genting Formation consists of sandstone, clay (Early Triassic), Klabat Granite (Late Jurassic-Early Triassic) and Alluvial sediments (Quaternary). Alluvial monazite containing 0.071 to 3.574%, zircon from 0.172 to 10.376%, xenotime from 0.15 to 3.023% of the weight of MB from 10.73 to 168.072 grams. The presence of rare earth (RE) metals is derived from the mineral monazite, xenotime, zircon that was derived from granitic rocks of Klabat. Rare earth (RE) distributed in the eastern part of the study area which occupies the valley of the river

Strengthening the Managerial Roles of Bank Indonesia as a Lender of Last Resort in Facing National Economic Uncertainty

Indonesia is currently in uncertainty regarding national economic development. The government has taken various preparatory steps to prevent negative impacts on the national economy. However, these efforts still need to be supported by law to provide certainty for policymakers in carrying out their duties and authorities, including Bank Indonesia (BI) as Lender of Last Resort (LoLR). This research explores, discovers, and analyzes legal issues related to BI's role as LoLR in overcoming the economic crisis. Methodologically, this analysis uses normative legal research methods with a conceptual approach and a statutory approach in building its arguments. The findings show the need to strengthen legal certainty regarding BI's authority as LoLR. This includes a Government Regulation instead of Law followed up by issuing a Joint Decree between the Minister of Finance, BI, and Law Enforcement Institutions

A TOUCH OF LOCAL WISDOM: THE STUDENTS’ VOICE

This research aims at designing local culture based digital comics for eighth year students of SMP Negeri 1 Kalipuro, Banyuwangi, East Java, Indonesia.  These are designed based on the English syllabus of reading skill and are developed in order to improve the students’ reading comprehension skill, especially in comprehending narrative texts. Also, it aims at preserving local wisdoms of Banyuwangi through English language teaching. The research and development steps comprise some steps adapted from the pattern developed by Borg and Gall. The researchers administered need analysis to 35 students in class VIII.1 in order to gather information dealing with the materials and media in English language teaching and the need on local culture based digital comics. The data was taken from questionnaire, interview, and document analysis. The results of need analysis reveal that the students need to be taught narrative texts with local culture content and a suitable interesting media in the form of digital comics.Keywords: local wisdom, need analysis, comics, reading

DIALEKTIKA BAHASA JAWA DALAM ADAT PERANG BANGKAT SUKU OSING KECAMATAN SINGOJURUH

ABSTRACTPerang Bangkat Ceremony is one proof of the diversity of cultures in Banyuwangi.

From the explanationabove, the writer would like to examine further the meaning contained in the BangkatCustomary Ceremony as an effort to increase knowledge about Javanese language andcultural heritage which are intended to increase love and care for the BangkatCustomary Customs in the modernization era. Therefore the authors feel the need tofurther study the customs of warfare and conduct research with the title "Dialogue ofJavanese Language in the Form of Osing Tribal War Sing Singuruh Subdistrict" Themethod used in descriptive qualitative data analysis with interactive analysis techniquesand using the checking of findings by triangulation source.Keywords: Javanese dialectic, Perang Bangka

Preserving Local Culture through Digital Comics

Digital environment offers teachers and students with a plethora of information and resources for learning. Nowadays, students who are mostly digital natives are used to utilizing technology in their daily life. This condition should make teachers as technology leaders responsible to provide a good learning environment where the students are involved in their own learning and that best suits to them in in a particular context. Therefore, this study aimed at developing local culture based digital comics for narrative reading comprehension and inserting local culture of Banyuwangi in English language teaching. This study followed the research and development design adapting the pattern developed by Borg and Gall. Based on the result of need analysis administered to students in class VIII of SMPN 1 Kalipuro, Banyuwangi, the product was developed by inserting local culture content into narrative texts in the form of digital comics. The digital comics had two titles: The Dance Competition and The Legend of Banyuwangi. The product was validated by the experts and tried out to the students. The result showed that the local culture based digital comics were applicable to be used in the teaching and learning narrative text reading comprehension

Evaluasi Keseragaman pada Sembilan Galur Jagung Manis (Zea mays L. saccharata Sturt) Generasi S5

Jenis jagung manis atau yang sering disebut sweetcorn banyak dikonsumsi karena memiliki rasa yang lebih manis dibandingkan dengan jagung biasa. Upaya meningkatkan produktivitas jagung manis adalah dengan menggunakan benih hibrida. Hibrida yang berpotensi hasil tinggi dihasilkan dari pasangan galur inbred dari populasi yang memiliki kelompok heterotik yang berbeda. Galur inbred dihasilkan setelah melalui proses silang dalam (selfing) dan seleksi untuk karakter yang diinginkan selama lima sampai tujuh generasi. Selfing yang dilakukan pada tiap generasi, akan menunjukkan nilai keseragaman yang berbeda pada setiap tingkat generasi. Keseragaman generasi berikutnya lebih tinggi dibandingkan generasi sebelumnya. Evaluasi kesera-gaman sebagi bentuk pengembangan inbred tahap pertama, bertujuan untuk menilai nilai keseragaman tanaman. Tujuan dari penelitian ini, yaitu untuk mengetahui keseragaman karakter galur-galur jagung manis dan menentukan galur yang dapat digunakan sebagai calon tetua hibrida. Penelitian dilaksanakan Mei-September 2018 di Desa Areng-areng Kelurahan Dadaprejo, Kota Batu. Berdasarkan hasil penelitian, semua galur menunjukkan nilai yang berbeda nyata pada analisis ragam pada semua variabel kecuali tinggi tongkol, umur panen, panjang biji dan lebar biji. Nilai KKG dan KKF pada variabel yang diamati menunjukkan nilai yang rendah pada hampir seluruh variabel kecuali husk cover dan un-tip filling yang memiliki kriteria sedang. Galur yang berpotensi dalam pembentukan varietas hibrida adalah 3-4-5+69L. Galur tersebut memiliki nilai keseragaman karakter kualitatif yang terbaik dan karakter kuantitatif yang unggul dibandingkan galur lainnya
