Abstract

Pandemic conditions, which require people to limit their space, have increased their need for information. This pandemic has also had a major impact on libraries. The most pronounced impact is the service that is not optimal because there are rarely visitors and savings so that it only serves borrowing and book services. This pandemic also makes regional libraries a digital library application and provides education about libraries via radio. This study aims to examine the library during the pandemic, how the benefits of using the digital library application “Perpusda Wonosobo”, and the analysis of having radio mass media in providing educational information about the library. This research uses the descriptive qualitative method. How to obtain data is structured interviews and observations. Researchers see what, where, and how the subject will be extracted information. The results of this study indicate that marketing through promotion makes the use of the digital library application “Perpusda Wonosobo” statistically increased during the pandemic. More and more people are using this digital library application to meet their information needs without having to interfere with the mobility of life during a pandemic. The use of radio media is also an effective secret to introduce to the general public about libraries and education from the library itself. Strong radio makes educational broadcasts more attractive and can reach the public. Furthermore, from this study, more and more people are using digital library applications because they are available in access and use. In the use of radio, information about the library can reach rural areas so that listeners from various backgrounds can listen to it because it is delivered in a language that is easily recognized. Introduction to libraries can also reach areas that have difficulty accessing the internet.

Abstract

Daerah penyelidikan terletak di Kecamatan Rao, Kabupaten Pasaman, Provinsi Sumatera Barat, secara geologi disusun oleh batuan metamorf (sabak, gneis), granodiorit, batuan vulkanik (lava andesit, breksi vulkanik), batuan sedimen dan endapan aluvium. Secara tektonik wilayah Rao berada dalam zona sesar Semangko yang berarah baratlaut-tenggara, sedangkan pola struktur lokal berarah timurlaut-baratdaya. Alterasi yang yang teramati pada batugamping marmeran ditandai dengan hadirnya epidot, garnet, karbonat dan urat-urat kuarsa akibat dari adanya intrusi granodiorit. Kehadiran mineral tersebut menunjukkan bahwa mineralisasi yang terbentuk mempunyai tipe skarn. Asosiasi mineralisasi logam berdasarkan analisis mineragrafi terdiri dari magnetit, hematit, kalkopirit, bornit, kovelit, kalkosit dan pirit dengan tekstur mineral yang beragam. Mineral mangan teridentifikasi secara megaskopis. Hasil pengamatan dengan menggunakan Scanning Electron Microscope (SEM) menunjukkan bahwa jenis mineral garnet di daerah Tarung Tarung diinterpretasikan berupa spessartit (Mn3Al2(SiO4)3) dan andradit (Ca3Fe(SiO4)3). Di bagian barat intrusi dijumpai kandungan besi tinggi dengan Fe total antara 59,39% s.d. 64,04%, nilai P sangat rendah (0,1%), TiO2 nilai tertinggi 0,84%. Magnetit yang berasosiasi dengan garnet ditemukan pada zona kontak antara intrusi granodiorit dengan batugamping marmeran di Bukit Gadang Lange. Hal ini menunjukkan adanya pengaruh larutan hidrotermal bersuhu tinggi yang masuk ke dalam batuan karbonat sehingga terbentuk mineralisasi tipe skarn.
