Abstract

Daerah penelitian secara administratif terletak di Kecamatan Batu Putih, Kabupaten Kolaka Utara, Provinsi Sulawesi Tenggara. Diketahui saat ini perkembangan teknologi dunia mengarah ke industri yang lebih ramah lingkungan, sehingga kebutuhan akan unsur-unsur baru yang ramah lingkungan menjadi perhatian dunia internasional. Kobalt secara global juga meningkat secara signifikan dengan tingkat pertumbuhan sebesar 7-13 % per tahun hingga mencapai 390 ribu ton pada tahun 2030. Berdasarkan penelitian-penelitian sebelumnya Kobalt banyak terdapat pada lapisan profil laterit yang keberadaanya melimpah di Sulawesi Tenggara khususnya di Kabupaten Kolaka Utara. Pada penelitian ini bertujuan untuk mengetahui hubungan karakteristik profil laterit terhadap pengkayaan Kobalt laterit  yang ada di daerah penelitian (1), dan untuk mengetahui persentase keterdapatan Kobalt pada lapisan profil laterit (2). Pengambilan data dilakuan dengan 2 metode yaitu metode test pit dan pemboran. Unsur yang terkandung dalam profil laterit dianalisis menggunakan metode XRF. Hasil uji XRF akan menunjukan profil laterit didapat dibagi menjadi tiga yatu limonit, saprolit dan bedrock. Zona pengkayaan kobalt ditemukan pada lapisan limonit yaitu mencapai 0.278%, sedangkan pada zona saprolit hanya sebesar 0.09%.

Abstract

Area studi terletak pada daerah Laronanga Kecamatan Andowia Kabupaten Konawe Utara, Sulawesi Tenggara. Studi ini bertujuan untuk menentukan karakteristik batuan ultramafik berdasarkan analisis petrografi dan geokimia. Analisis petrografi digunakan untuk menentukan nama batuan sedangkan analisis geokimia dengan XRF (X-Ray Fluorescence) bertujuan untuk menentukan jenis magma, afinitas magma dan lingkungan asal magma. Hasil analisis petrografi menunjukkan bahwa batuan ultramafik area studi merupakan batuan beku ultramafik jenis peridotit-harzburgit. Adapun hasil analisis XRF batuan memperlihatkan bahwa jenis batuan beku di area studi adalah batuan peridotit-gabro dengan tipe afinitas/seri magmanya termasuk ke dalam seri tholeitic series, serta lingkungan asal terbentuk magma adalah berasal dari Oceanic Ridge and Floor atau Mid Oceanic Ridge (MOR).

Abstract

It has been conducted a geomagnetic research in the geothermal area of Sonai Village and its surroundings, Puriala, Konawe Regency, which aims to identify the structure of the subsurface using the pseudo-gravity method. After performing diurnal and IGRF corrections on the measurement data, the residual magnetic field anomaly is obtained around -150 to 90 nT. Furthermore, transformation process using the pseudo-gravity method is carried out, and the anomaly contour density is obtained around -0.07 to 0.06 mGal. The results of 2D modeling of 2 slices on the residual magnetic anomaly map that have undergone pseudo-gravity transformation show that the subsurface layers of the research area are composed of 3 formations. Layers with density values of 1.5 and 2.5 g/cm3 are thought to be Alluvium Deposits in the form of sand and clay, layers with density values of 2.6 and 2.78 g/cm3 are sandstone and conglomerate in the Alangga Formation, and a layer with a density value of 2.84 g/cm3 is peridotite in the Ultramafic Complex (bedrock layer). In addition, several minor faults were also found, and among them 2 minor faults adjacent to geothermal manifestation are located at coordinates of approximately 4o1’16.149” South Latitude dan 122o7’9.609” East Longitude with a distance of ±15 meters, and at coordinates of approximately 4o1’23.388” South Latitude dan 122o7’24.326” East Longitude which is ±28 meters from the manifestation. These minor faults cut through the peridotite layer and the conglomerate layer, and are thought to be the migration path of hot fluids towards the surface.

Tujuan dari penelitian ini untuk mengetahui tingkat kestabilan pantai diperairan Pelabuhan Mawasangka, Kecamatan Mawasangka, Kabupaten Buton Tengah, Sulawesi Tenggara. Metode dalam penelitian ini dengan pengumpulan data dari hasil pengukuran di lapangan, observasi, dan dokumentasi, penelitian. Pengambilan sampel dengan teknik sampling purposive. Metode penentuan kestabilan pantai menggunakan metode Sunamura dan Horikawa karena mampu memberikan estimasi kuantitatif terhadap perubahan garis pantai yang disebabkan oleh gelombang laut, terutama dalam konteks pengaruh arus sejajar pantai terhadap transportasi sedimen. Hasil penelitian menunjukan bahwa terjadi Akresi atau abrasi ringan diperairan Pelabuhan Mawasangka di empat titik Stasiun penelitian Stasiun (1) dengan nilai 0,295289, Stasiun (2) 0,364086, Stasiun (3) 0,364086 dan Stasiun (4) 0,295289. Kondisi penelitian ini dipengaruhi oleh tinggi gelombang, panjang gelombang, kelandaian pantai, serta ukuran butiran sedimen.

Abstract

It has been carried out research with the aim of determining the subsurface structure at the geothermal area of Sonai Village and its surroundings, Konawe Regency. The data used are magnetic data obtained through field measurements at 126 points in the N180oS direction. After the data were subjected to diurnal and IGRF corrections, a residual (local) magnetic field anomaly of around -150 nT to 90 nT was obtained. On the residual magnetic anomaly map which has been reduced to the Pole (RTP), the Euler Deconvolution (ED) method is applied to the Index Structure N=0 to estimate the subsurface structure in the form of the presence of minor faults, and it is known that there are 5 minor faults at a depth of around 9 to 38 meters. Information on the existence of these faults is then used in 2D modeling. Modeling results show that these minor faults cut through two rock layers, which are the layers composed of conglomerate rocks from the Alangga Formation and peridotites as bedrock from the Ultramafic Complex. One of the minor faults closest to the manifestation area (hot spring) is at coordinates around 4o1’12.412” S and 122o7’24.263” E to 4o1’15.532” S and 122o7’19.561” E with a distance of ±15 meters. The existence of these minor faults is thought to be the migration routes for heat flow or conduction to the surface at the geothermal area of Sonai Village and its surroundings.

Abstract

Revegetation based on the ornamental landscape is one of the efforts to reduce the surface of urban heat islands (SUHI), the intensity of which is always influenced by land surface temperature (LST). The focus of the PBM scheme community service program in the scope of PKM is disaster mitigation due to climate change, significantly reducing the risk of disasters due to LST. The program aims to reduce SUHI through vegetation modification using edible and ornamental plants as elements forming the landscape with a public education approach and revegetation actions. The results of PBM-PKM in public education activities show the high enthusiasm of the community in participating in activities and show that the level of partner understanding of the concept of revegetation has reached 100%. As a result of revegetation activities, as many as 342 edible plants and ornamental plant seeds invested in the community were successfully planted in the Asy-Syifaa Mosque, Kendari City landscape. The achievement of increasing the level of community empowerment shows a significant increase in understanding regarding the importance of creating vegetation in the yard landscape to reduce the risk of disasters due to rising LST through vegetation, which has been understood 100% by target partners. The results of monitoring and evaluating the growth of edible plants and ornamental plants as landscape-forming elements were able to grow well in the Asy-Syifaa Mosque area.

Abstract

The research area is administratively located at Toronipa, Soropia District, Konawe Regency, Southeast Sulawesi Province. The purpose of this study was to determine the type of limestone, the diagenes process and the environment of limestone diagenesis in the Meluhu Formation. The method used in this research is the petrographic method. The results showed that the types of limestone in the study area were wackestone and packstone which had undergone a diagenesis process in the form of cementation, microbial micritization, neomorphism, and dissolution. The limestone diagenesis environment in the Meluhu Formation originates from the marine phreatic, meteoric phereatic, and meteoric vadose diagenesis environments.
