Abstract

Manifestasi mata air panas di wilayah ini merupakan indikasi adanya sistem panas bumi bertemperatur rendah akibat aktivitas tektonik. Metode penelitian meliputi pengambilan sampel air secara langsung di lapangan untuk dianalisis sifat fisika dan kimianya. Parameter fisik yang diukur meliputi suhu, pH, warna, bau, rasa, TDS, dan debit air, sedangkan analisis kimia dilakukan menggunakan metode Atomic Absorption Spectrophotometry (AAS). Hasil pengamatan menunjukkan bahwa mata air panas Kaongkeongkea memiliki suhu 35,6°C, pH 1,59, TDS sebesar 793 ppm, tidak berwarna, berbau sulfur, dan tidak berasa. Kandungan ion utama yang terdeteksi meliputi Cl⁻ (923 mg/L), HCO₃⁻ (187,2 mg/L), dan SO₄²⁻ (17,26 mg/L). Berdasarkan perbandingan ketiga ion utama tersebut, air panas daerah Kaongkeongkea diklasifikasikan ke dalam tipe klorida (mature water) yang menandakan asal fluida dari reservoir dalam pada sistem panas bumi aktif. Hasil perhitungan geotermometer silika menunjukkan suhu reservoir bawah permukaan sekitar 144°C, yang mengindikasikan sistem panas bumi bertemperatur menengah. Ciri geokimia tersebut memperlihatkan bahwa fluida panas di Kaongkeongkea terbentuk melalui interaksi antara air meteorik dan batuan penyusun sedimen serta dipengaruhi oleh aktivitas struktur tektonik. Kajian ini memberikan kontribusi penting dalam memahami potensi energi panas bumi di Pulau Buton dan mendukung pengembangan pemanfaatan sumber daya panas bumi secara berkelanjutan di wilayah Indonesia bagian timur.

Abstract

Samaenre Village has supergene copper mineralisation in rocks of the Kalamiseng Formation and geographically adjacent to diorite intrusions. The mineralisation outcrops are associated with alteration that changes the volcanic rocks of the Kalamiseng Formation. Previously, research was conducted on the characteristics of hydrothermal alteration and its alteration type in the Tonra area of Bone Regency, South Sulawesi Province. However, the research did not specifically examine the types of copper ore minerals and their associations and did not determine the copper content at the research location. The purpose of this study was to determine the types of copper ore minerals, associated minerals and copper  content in samples in the study area. The analytical method used in this research is first carried out megaskopis analysis to determine the physical properties of the sample. After that, laboratory analyses of mineragraphy, X-Ray Diffraction (XRD) and Atomic Absorption Spectrophotometer (AAS) were carried out. The results of megascopic analysis of the two research samples have a fresh blue colour and a fresh green colour with a brown weathered colour, there are calcite minerals and also tend to oxidise. Copper ore minerals found based on Mineragraphy and XRD analysis are Cuprorhodsite (CuFeRh2S4), Auricuprite (Cu3Au), Tenorite (CuO), Cuprite (Cu2O). The associated minerals found based on the results of Mineragraphy and XRD analysis are Cupalite (Al5Cu5), Diopside (CaMgSi2O6), Siderite (FeCO3), and Diopside (CaMgSi206). The copper (Cu) content in samples from the study area based on AAS analysis results ranged from 0.11 % to 0.17 % Cu

Abstract

Limestone mining for cement plants uses a blasting method to break the material. Blasting production is considered successful when it can achieve production targets based on tonnage of uncovered rock, efficient use of explosives, grain size or rock fragmentation, and environmental impact. This research aims to analyze the blasting geometry on the production results at the research location by knowing the initial design, the actual blasting geometry, and the geometry recommendation using the C.J. Konya method. In addition, researchers also know the explosives used, the production results in the form of material fractionation using the Kuz-Ram method and the tonnage of uncovered rocks. The initial design with a burden of 3.4 m, spacing of 3.4 m, hole depth of 5.9 m, and ANFO explosives per hole of 33 kg produced 147.31 tonnages. The actual geometry with a burden of 1.7 m, spacing of 3.5 m, hole depth of 6.0 m and ANFO explosives per hole of 26.73 kg produced a 77.11 tonnage. The actual geometry resulted in a blasting production of 6,941 tonnes per day, which did not meet the company's production target 10,639. The fragmentation calculation results obtained an average size in the field of 15.29 cm, which meets the required screening or sieve criteria of 0.80 - 1.00 m. The size of the fragments also follows the sieve calculation using the Kuz-Ram method, with a 100 cm sieve passing only 0.01%. Based on this, the company is recommended to make geometry changes to achieve the production tonnage target that has been set.

Abstract

The Teaching Campus is one of the Ministry of Education and Culture's programmes in the form of Merdeka Belajar-Kampus Merdeka (MBKM) activities. Teaching activities at the Teaching Campus include four aspects; literacy and numeracy activities, technology adaptation and school administration. However, this research is more focused on literacy and numeracy based on the conditions of SDN 7 Tekolabbua, which after initial observations found that the literacy and numeracy skills of SDN 7 Tekolabbua students are still minimal, so this Teaching Campus activity is important to do. This study aims to improve the literacy and numeracy skills of students of SDN 7 Tekolabbua. The research method used is observation and planning of literacy and numeracy support activities. These supporting activities are: implementation of additional classes (maths guidance), revamping the reading corner in each class as well as literacy and numeracy media, procurement of mading, revamping the school library, reading activities for 10-15 minutes before class starts, and reading guidance in the library. The results showed that the implementation of literacy and numeracy support activities during the Teaching Campus programme was able to improve literacy and numeracy skills at SDN 7 Tekolabbua. Students who were previously lacking in literacy and numeracy skills are now showing significant improvements in literacy and numeracy skills, so this 4th batch of campus teaching activities has proven effective in improving the literacy and numeracy skills of students at SDN 7 Tekolabbua.
