Abstract

Inkonsistensi teori C merupakan anomali dimana teori C tidak berlaku dalam proses Agitated Leaching. Hal ini menuntut penjelasan sehingga banyak peneliti berspekulasi untuk menjelaskannya. Contohnya teori A yang kontra- intuitif dan teori B yang cenderung menentang teori A. Dalam penelitian ini telah dilakukan penyelidikan terhadap teori A dan B melalui pendekatan tidak-langsung dengan variabel terikat dari proses Agitated Leaching adalah Total Dissolved Solid (TDS), laju pengadukan sebagai variabel bebas dan variabel tetap adalah rasio solid-likuid (1:20 Gr/mL) dan lama pengadukan (10 menit). Proses pelaruran dilakukan pada keadaan STP dan membatasi proses hanya pada tahap pelarutan sampel menggunakan HNO3 5%. Sampel yang digunakan adalah pasir tailing timah. Hasil penelitian menunjukkan bahwa inkonsistensi terjadi pada laju pengadukan 1000 rpm. Teori A1 tidak dapat disimpulkan keberlakuannya dalam proses pelindian tailing timah. Teori A2 berlaku dalam proses pelindian tailing timah. Teori B berlaku dalam proses pelindian tailing timah.

Abstract

As one of unique non-volcanic geothermal field in Indonesia, mapping the groundwater flow in Nyelanding Village, South Bangka is essential as preliminary study for further exploration activity if the geothermal manifestation. In order to achieve this goal, we conduct a research using natural electrical properties of subsurface, Self-Potentials (SP) method. In this study, fixed-based technique was used where the spacing between measurement stations is the multiplication of 10 m along three lines at the study area. Raw field data (potential value) was corrected to diurnal and closure corrections. Further, SP anomaly was plotted and combined with topography data to be analyzed. The result shows potential value raging from -25mV to 100mV which in agreement with the lowest and highest elevation in topography map, respectively. This means, these values are controlled by topographic feature in the study area. Thus, in conclusion, the groundwater flows from the West to North East and South East part of the study area

Abstract

Covid-19 merupakan salah satu permasalahan yang melanda di seluruh Dunia. Perlahan Covid-19 menyebar ke seluruh Negara, serta kota-kotanya. Kepulauan Bangka Belitung merupakan salah satu provinsi di Indonesia yang mulai terpapar Covid-19. Permasalahan tersebut ternyata menimbulkan dampak yang sangat buruk termasuk di Desa Penyak. Melihat beberapa permasalahan yang ada, Tim pelaksana pengabdian Universitas Bangka Belitung melakukan beberapa langkah untuk membantu warga dan perangkat Desa untuk mengatasi beberapa permasalahan. Beberapa hal yang dilakukan antara lain Sosialisasi dan Pembagian Sembako. Berdasarkan hasil respon bebrapa warga dapat dikatakan bahwa kegiatan-kegiatan yang dilaksanakan banyak informasi baru bagi warga.

Abstract

Central Bangka is one area that has geothermal potential such as the Terak and Keretak area. These area have hot spring manifestation. Geothermal manifestations in Bangka is the type of non-volcanic radiogenic geothermal. Origin sources of this manifestation suspected from rocks run into the crack, folds and faults. The purpose of this study was to identify rock speading in geothermal area and it’s correlation between geothermal manifestation in Terak and Keretak. The data obtained from the TOPEX/Poseidon satellite is in the form of FAA (Free Air Anomaly) data. The data is then corrected using Burger correction and field correction. Spectral analysis was performed by Fourier transform with moving average filter. The results showed that Complete Bouger Anomaly has 13 mGal-39 mGal. Regional anomaly has 5,4 mGal - 9.8 mGal. Residual anomaly has 7 mGal sampai 29 mGal. There area was consist of intrusive granite rock from the Granite Klabat formation, clas and sandstone from Tanjung Genting Formation. Gravity anomaly shown Geothermal Terak and Keretak are composed of the same distribution of rock.

Abstract

Padang Mulya Village, Koba District is part of the Koba Groundwater Basin area. This area has the potential of abundant aquifer layers. An aquifer is a layer of rock that can store water in large quantities. However, the continued increase in exploration of the aquifer layer will result in damage to the aquifer environment. In this case it is necessary to identify the aquifer layers to determine the depth and lithology of the constituent rocks. The resistivity geoelectric method of the dipole-dipole configuration is the most sensitive geophysical method for identifying aquifer layers. Measurements were made on six tracks to obtain data variations on current strength and potential difference. From these data variations in apparent resistivity values will be obtained. 2D modeling of the apparent resistivity value using the backward modeling method is carried out on each track in order to obtain a 2D cross-section of the subsurface structure. The 2D section of each track has an aquifer layer with a depth of 0 meters to 20 meters and is composed of clay, loamy sand, rather dense gravel sand and sandstone.
