Abstract

Geophysical research has been done on mapping distribution of metal deposits in the field "X" PT Newmont Nusa Tenggara using induced polarization geoelectric method pole-dipole configuration. Measurements performed using IRIS intrument type Elrec Pro where measurements of seven lines with length 2.3 km and electrode spacing 100 m. Induced polarization data furtheranalyzed by using Res2dinv version 3.56 and Surfer 10. Interpreted based on the parameters of chrageability and resistivity that correlated with regional geological information from the study area. As a result, the structure of rocks beneath the surface lithology research area consists of five units major rock that is tuffan claystone unit, sandstone tuffan unit, limestone unit, lava-brecciaunit, and andesite-basalt unit. Mineralization zone at the high chargeabilitas at 69.7 to 155 msec range supported by the low resistivity in the range of 4.21 to 26.5 Ωm which straight of anomalies in West-East direction at the depth of ± 50-400 m.

Abstract

Banyu Ajlok is one of the tourist destinations in Purwodadi Village, Tirtuyudo District, Malang Regency. Banyu Anjlok is located in the southern mountainous area, this area shows the existence of ancient volcanic activity from the south of Java which causes Banyu to have a geodiversity that can be used as a geological heritage. The purpose of this study is to identify geodiversity in the Banyu plummeting area as the basis for geological-based tourism development. The methods used include geological surveys and assessments of geological values using the technical guidelines of the Geological Survey Center by the Geological Survey Center which include scientific values, educational values, tourism values and risk of degradation. The results showed that the lithology of Banyu plummeted including andesite, basalt, ryolite, andesite breccia, sandstone, grandiorit and plant fossils. In addition, geological structures that can be found are  joints. The assessment results show a scientific value of 76.25%, an educational value of 75%, a tourism value of 66.25% and a risk of degradation of 235. Based on the results of the assessment, Banyu plummeting has potential as a geological heritage site in terms of geological diversity and risk of degradation.

Abstract

Geoelectrical resistivity method is popular technique for subsurface mapping of groundwater, mining exploration, and structural geology. For case study in Tidar Plateau which characterized by hard rock of volcanic breccia, lava, tuff, and conglomerate,  the groundwater system occurs only by the secondary porosity (faulting, facturing, and weathering). Therefore it becomes difficult task for determine position of good well site in Tidar Plateau. Geoelectrical technique by Schlumberger configuration was choosen to investigated the ground water system in this area. Total 5 Vertical Electrical Sounding (VES) acqusition point (400 m length measurement; spacing 10 m) for data measurement with coverage area about 400 x 400 m2. For data processing was used IP2Win, Progress3, and RockWork 16.  The data processing results showed high accuration with avarage Root Mean Square (RMS) error about 0.3 – 8.3 %. According to resistivity results, the study area has resistivity between  0.3– 2.5x104 . The rocks which have resistivity between 0.3 – 12.52  interpreted as sandy-clay; 12.52 – 50  interpreted as wet sandstone (aquifer); 129 – 178  interpreted as conglomerat; 700 – 1300  interpreted as tuff, sand, and dry gravel; 2600 – 2.5x104  interpreted as volcanic breccia. This geoelectrical results has succesful finding the fresh water at VES 5 after drilled at depth 100 m at wet sandstone formation. To findout distrubution of aquifer layer, a three-dimensional (3D) resistivity model was developed. The 3D resistivity model shows the aquifer layer image look the dome-like structure and image the fracture regions which becomes the pathway of groundwater system.

Abstract

Abstrak Tingginya kasus HIV/AIDS di Indramayu, dengan 4.970 kasus HIV dan 581 kasus AIDS pada tahun 2022, menunjukkan urgensi untuk upaya pencegahan dan penanganan yang efektif, terutama pada kelompok rentan seperti pekerja migran. Program pengembangan kapasitas kader kesehatan dirancang untuk meningkatkan peran kader dalam memberikan edukasi, konseling, dan pendampingan kepada pekerja migran. Tujuannya adalah membekali kader dengan keterampilan komunikasi, pemahaman kebijakan kesehatan, dan metode pencegahan HIV/AIDS, serta mendorong perubahan perilaku sehat pada kelompok sasaran. Metode yang digunakan mencakup pelatihan teknis, komunikasi interpersonal, dan praktik pembuatan media edukasi digital .Hasil pengabdian menunjukkan bahwa sebanyak 65% kader mengalami peningkatan pengetahuan melalui pre-test dan post test. Program ini membuktikan bahwa pemberdayaan kader berbasis komunitas adalah strategi efektif untuk mendukung pencapaian SDGs ke-3 yaitu Kesehatan dan Kesejahteraan. Abstract The high prevalence of HIV/AIDS in Indramayu with 4,970 HIV cases and 581 AIDS cases reported in 2022 underscores the urgent need for effective prevention and intervention strategies, particularly among vulnerable populations such as migrant workers. This community empowerment program was designed to enhance the capacity of community health cadres in delivering education, counseling, and support services to potential and current migrant workers. The program aimed to equip cadres with essential communication skills, knowledge of health policies, and evidence-based HIV/AIDS prevention methods, while also promoting healthy behavioral change among target groups. Implementation methods included technical training, interpersonal communication workshops, and hands-on practice in developing digital educational media. The community service results showed that 65% of the health cadres demonstrated improved knowledge, as measured through pre-test and post-test assessments. This initiative demonstrated that community-based cadre empowerment is an effective strategy to support the achievement of Sustainable Development Goal 3 (Good Health and Well-being).
