Abstract

Exploration of gold mining in Pangalengan, Bandung is one of traditional and illegal method used by villager there. The exploration gives a lot of environmental damage such as landscape and structure changing, also pollution of nature because there is no control of sewerage system or tailing gold system for the likes of Mercury (Hg) and Lead / Plumbum (Pb). The objective of this research is to know the trend pattern of mining waste distribution in Pangalengan, Bandung using Electricity Method with measurement parameter of conductivity (EC), Total Dissolved Solid (TDS), and acidity level (pH). There were two methods to take the measurement, first, took the soil sample by using coring with 0.3 meters deep with 2 inch diameter at the riverbank and channel from the sewerage places which has heavy metal elements. And second is laboratory test. The increase in heavy metal trend pattern usually has an increase in mining areas, and decrease departs from mining area. Heavy metal hoarding usually take an increase in the area of upper course of the river, it happens allegedly because of he of water flow rate. Keywords: Gold Mine, Heavy Metal, EC, TDS, Environmental Geophysics, Pollutant, Heavy Metal, Hg, Pb.

Abstract

Despite the broadly usage in geophysical fields due to its non-intrusiveness, inexpensiveness and fast deployment, self-potential (SP) method still posses challenges in the interpretation. In this work, quantitative identification of SP parameters such as the shape factor of cylindrical and spherical objects, the depth of burial, the polarization angle and the electric dipole moment is addressed. Three approaches of quantitative interpretation are used, i.e., a derivative method, a least-squares method and an iterative inversion based on the Levenberg-Marquardt method. The above approaches were first tested on a theoretical synthetic model, where a close agreement between the presumed and calculated parameters was obtained. Application to the real data was conducted by analyzing the SP anomaly obtained from a buried cylindrical conductive object at certain depth.

Abstract

Quantitative numerical modeling of self-potential (SP) anomaly associated with subsurface electric current density that is attributed to cross-coupling between fluid flow and electrical conductivity distributions has been conducted. The modeling scheme was applied to an area in the vicinity area of Domas crater, Tangkuban Parahu volcano in West Java. The field surveys at domas were conducted from mid-2008 until mid-2009. The main objective of this researchis to obtain a quantitative model that is possible to explain the shallow convective hydrothermal system in the eastern side of the volcano by making comparison between SP anomaly measured on the surface with theoretical anomaly resulted from modeling. Since the modeling scheme requires information on the subsurface resistivity structure, we performed measurement and interpretation of 2-D resistivity at Domas crater. The measurement of CO2 emission that is commonly associated with magmatic gas migration patterns through fracture system was also carried out on the same SP and resistivity lines. Fluid velocity vector was calculated by solving the coupled Darcy’s and energy equations involving heat transfer terms by both convection and conduction. The subsurface electric current source distribution was calculated by solving the coupled equation of velocity and potential gradients. The results show that the fluid flow patterns around Domas Crater which in addition is controlled by topographic effect; it is also influenced by thermal fluid flows through relatively high permeability zone beneath the Domas Crater.

Abstract

Sungai Citarum merupakan sungai utama yang ada di Provinsi Jawa Barat yang sangat penting bagi kehidupan sosial dan ekonomi. Di bagian hilir, Sungai Citarum ini banyak melewati daerah pemukiman padat penduduk, daerah industri, dan bahkan pesawahan. Oleh karena itu, perlu kajian mengenai kondisi Sungai Citarum salah satunya dengan mengidentifikasi parameter electrical conductivity (EC), total dissolve solid (TDS), pH dan suhu serta karakteristik mineral magnetik pada sedimen melalui analisis sifat magnetik, mineralogi dan morfologi magnetiknya. Pengukuran parameter EC, TDS, pH dan suhu dilakukan secara in situ pada sampel air Sungai Citarum, pengukuran sifat magnetik dilakukan pada sampel sedimen yang telah dipreprasi, sedangkan pengukuran mineralogi dan morfologi dilakukan pada sampel sedimen yang telah diekstraksi. Sifat magnetik sedimen diketahui dari nilai suseptibilitas magnetik dual frekuensi yang diukur menggunakan Bartington Magnetik Susceptibilitymeter, sedangkan mineralogi dan morfologi magnetik diketahui berdasarkan hasil pengukuran scanning electron microscope–energy disperdsive x-ray (SEM-EDS) dan x-ray diffractometer (XRD). Hasil pengukuran secara in situ pada sampel air menunjukkan bahwa rentang nilai EC, TDS, pH dan suhu berturut-turut adalah (200–4120) mS/cm, (100–2060) ppt, 7,34–9,22, dan (26,8–32,6) oC. Sedangkan, hasil pengukuran sifat magnetik menunjukkan bahwa sampel sedimen Sungai Citarum bagian hilir memiliki nilai suseptibilitas magnetik frekuensi rendah (cLF) dengan rentang (65,00–173,80) x 10-8 m3/kg, sedangkan rentang nilai suseptibilitas magnetik frekuensi tinggi (cHF) adalah (64,90–165,70) x 10-8 m3/kg. Dari kedua pengukuran cLF dan cHF diperoleh rentang nilai cFD (%) sebesar 0,15–4,66. Selanjutnya, hasil analisis morfologi dari citra SEM-EDS dan analisis mineralogi berdasarkan pengukuran XRD menunjukkan dominasi jenis mineral magnetik pada sampel sedimen adalah magnetit. Mineral magnetit ini memiliki morfologi berbentuk oktahedral sebagai representasi mineral magnetik alami dan ada pula yang berbentuk spherule sebagai representasi mineral magnetik karena adanya proses oksidasi akibat kehadiran material antropogenik pada sedimen Sungai Citarum bagian hilir.

Abstract

Agricultural technology innovation such as application of low magnetic field and arbuscular mycorrhizal fungi (AMF) could improve growth of some vegetable plants, such as tomatoes.The objectives of the research were to determine: (1) the effect of low magnetic field treatment on germination of tomato seeds, and (2) the combined effect of mycorrhiza and magnetic field treatments on growth of tomato plants. The first experiment was conducted in the laboratory to test the germination of magnetized and non-magnetized seeds on different growing mediums. The second experiment was conducted in a screenhouse using Randomised Blocked Design with the treatments of exposure of magnetic field (0 and 0.2 mT) and AMF (Glomus sp., Gigaspora sp. and Combination of Glomus sp. and Gigaspora sp.). Both treatments were applied as pre-sowing seed treatments. Results revealed the exposure of seeds to magnetic fields increased the seedling germination percentage, especially in the treatments combined with Gigaspora sp. (90%). Further measurement of plant heights showed that magnetized seeds consistently showed a higher plant height compared to non-magnet treatments. Gigaspora sp. which applied either as single or in mixture with Glomus spp. have shown better effect than Gigaspora sp. alone on the growth of tomatoes

Abstract

Juvenile delinquency (such as smoking, drug use, and acts of bullying) is prone to occur after the COVID-19 pandemic and during digitalization, including students in Islamic-based schools. This study aims to examine the perceptions and attitudes of Islamic school students towards smoking, drugs, and bullying, the demographic differences, and the relationship between these variables. The survey was conducted by distributing 26 questions to 94 Islamic school students. Data were processed using descriptive analysis, comparative (t test and ANOVA) and correlation (pearson correlation test). The results showed that almost half of the students had smoked with the male predominance. Perception toward smoking, attitude towards drugs, and bullying were good in each group; shows the contribution of Islamic education to juvenile delinquency. However, perception towards cigarettes and drugs were significantly higher in the upper grade and anti-bullying attitudes were also significantly higher in the group of students who had never smoked. Based on the results of this study, perception towards smoking, attitude towards drugs, and bullying are interrelated so that handling one variable of juvenile delinquency can have an impact on other variables.

Abstract

Regional development in Panimbang District, Banten Province, Indonesia, is executed so that the tourism area is not centered solely on the west coast of Pandeglang but also in the surrounding area. The development is carried out in stages from government offices, education facilities, and public facilities. One of the public facilities to be built is a garden. This study aimed to evaluate the condition of the soil layers and fertility for garden construction. The resistivity method determines the soil layer pattern using dipole configuration. Remote sensing methods are used to assess land suitability and soil fertility. Land suitability based on agro-climatic data soil fertility based on physical and chemical parameters is taken from SoilGrids 250 m. The results of the resistivity method showed various values between 1 – 110 Ωm, and there are three layers of soil up to a depth of 3.58 m The first layer is assumed to be silty clay (15 – 30 Ωm), the second layer is assumed to be clay (1 – 5 Ωm), and the third layer is assumed to be silty and sandy soil (70 – 110 Ωm). Based on the remote sensing data, the first layer had an ideal bulk density and cation exchange value, but the pH value and nitrogen content are less ideal. The second layer had an ideal value of cation exchange capacity and pH, a rather ideal bulk density value, and a low nitrogen content and is considered a fertile layer of soil. Keywords: Remote sensing, resistivity, soil fertility, soil layers, SoilGrids 250 m

Abstract

The acoustic impedance inversion seismic method, carried out at the "EL" well in East Java,provides a description of the physical properties of subsurface rocks. This method involves identifying rocklayers, lithology types, porosity values, the presence of hydrocarbons, and fluids in the target zone usingboth well data and integrated seismic data. The data processing included the cross-plotting of acousticimpedance (AI) with gamma ray logs, porosity logs, and resistivity logs. We integrated seismic and welldata, picked horizons, and created AI inversion models. The based model inversion technique was used tocompare the synthetic model with the seismic data, aiming to obtain an AI value that closely represents theactual model. AI seismic inversion effectively separates lithological boundaries vertically and laterally,based on the selected picking horizon and created model. To enhance understanding of the lithology andhydrocarbon prospect zone in the study area, a cross-plot analysis was used to correlate the seismic inversionmodel. The results reveal that the study area represents a hydrocarbon prospect zone, with reservoir rocksconsist of coral and foram at a depth range of 2320 - 2430 ft.
